If the Work is provided as +Executable Code, the Licensor provides in addition a machine-readable copy of the Source Code of the Work along with +each copy of the Work that the Licensor distributes or indicates, in a notice following the copyright notice attached to +the Work, a repository where the Source Code is easily and freely accessible for as long as the Licensor continues to +distribute or communicate the Work. + +4.Limitations on copyright +Nothing in this Licence is intended to deprive the Licensee of the benefits from any exception or limitation to the +exclusive rights of the rights owners in the Work, of the exhaustion of those rights or of other applicable limitations +thereto. + +5.Obligations of the Licensee +The grant of the rights mentioned above is subject to some restrictions and obligations imposed on the Licensee. Those +obligations are the following: + +Attribution right: The Licensee shall keep intact all copyright, patent or trademarks notices and all notices that refer to +the Licence and to the disclaimer of warranties. The Licensee must include a copy of such notices and a copy of the +Licence with every copy of the Work he/she distributes or communicates. The Licensee must cause any Derivative Work +to carry prominent notices stating that the Work has been modified and the date of modification. + +Copyleft clause: If the Licensee distributes or communicates copies of the Original Works or Derivative Works, this +Distribution or Communication will be done under the terms of this Licence or of a later version of this Licence unless +the Original Work is expressly distributed only under this version of the Licence — for example by communicating +‘EUPL v. 1.2 only’. The Licensee (becoming Licensor) cannot offer or impose any additional terms or conditions on the +Work or Derivative Work that alter or restrict the terms of the Licence. + +Compatibility clause: If the Licensee Distributes or Communicates Derivative Works or copies thereof based upon both +the Work and another work licensed under a Compatible Licence, this Distribution or Communication can be done +under the terms of this Compatible Licence. For the sake of this clause, ‘Compatible Licence’ refers to the licences listed +in the appendix attached to this Licence. Should the Licensee's obligations under the Compatible Licence conflict with +his/her obligations under this Licence, the obligations of the Compatible Licence shall prevail. + +Provision of Source Code: When distributing or communicating copies of the Work, the Licensee will provide +a machine-readable copy of the Source Code or indicate a repository where this Source will be easily and freely available +for as long as the Licensee continues to distribute or communicate the Work. +Legal Protection: This Licence does not grant permission to use the trade names, trademarks, service marks, or names +of the Licensor, except as required for reasonable and customary use in describing the origin of the Work and +reproducing the content of the copyright notice. + +6.Chain of Authorship +The original Licensor warrants that the copyright in the Original Work granted hereunder is owned by him/her or +licensed to him/her and that he/she has the power and authority to grant the Licence. +Each Contributor warrants that the copyright in the modifications he/she brings to the Work are owned by him/her or +licensed to him/her and that he/she has the power and authority to grant the Licence. +Each time You accept the Licence, the original Licensor and subsequent Contributors grant You a licence to their contributions +to the Work, under the terms of this Licence. + +7.Disclaimer of Warranty +The Work is a work in progress, which is continuously improved by numerous Contributors. It is not a finished work +and may therefore contain defects or ‘bugs’ inherent to this type of development. +For the above reason, the Work is provided under the Licence on an ‘as is’ basis and without warranties of any kind +concerning the Work, including without limitation merchantability, fitness for a particular purpose, absence of defects or +errors, accuracy, non-infringement of intellectual property rights other than copyright as stated in Article 6 of this +Licence. +This disclaimer of warranty is an essential part of the Licence and a condition for the grant of any rights to the Work. + +8.Disclaimer of Liability +Except in the cases of wilful misconduct or damages directly caused to natural persons, the Licensor will in no event be +liable for any direct or indirect, material or moral, damages of any kind, arising out of the Licence or of the use of the +Work, including without limitation, damages for loss of goodwill, work stoppage, computer failure or malfunction, loss +of data or any commercial damage, even if the Licensor has been advised of the possibility of such damage. However, +the Licensor will be liable under statutory product liability laws as far such laws apply to the Work. + +9.Additional agreements +While distributing the Work, You may choose to conclude an additional agreement, defining obligations or services +consistent with this Licence. However, if accepting obligations, You may act only on your own behalf and on your sole +responsibility, not on behalf of the original Licensor or any other Contributor, and only if You agree to indemnify, +defend, and hold each Contributor harmless for any liability incurred by, or claims asserted against such Contributor by +the fact You have accepted any warranty or additional liability. + +10.Acceptance of the Licence +The provisions of this Licence can be accepted by clicking on an icon ‘I agree’ placed under the bottom of a window +displaying the text of this Licence or by affirming consent in any other similar way, in accordance with the rules of +applicable law. Clicking on that icon indicates your clear and irrevocable acceptance of this Licence and all of its terms +and conditions. +Similarly, you irrevocably accept this Licence and all of its terms and conditions by exercising any rights granted to You +by Article 2 of this Licence, such as the use of the Work, the creation by You of a Derivative Work or the Distribution +or Communication by You of the Work or copies thereof. + +11.Information to the public +In case of any Distribution or Communication of the Work by means of electronic communication by You (for example, +by offering to download the Work from a remote location) the distribution channel or media (for example, a website) +must at least provide to the public the information requested by the applicable law regarding the Licensor, the Licence +and the way it may be accessible, concluded, stored and reproduced by the Licensee. + +12.Termination of the Licence +The Licence and the rights granted hereunder will terminate automatically upon any breach by the Licensee of the terms +of the Licence. +Such a termination will not terminate the licences of any person who has received the Work from the Licensee under +the Licence, provided such persons remain in full compliance with the Licence. + +13.Miscellaneous +Without prejudice of Article 9 above, the Licence represents the complete agreement between the Parties as to the +Work. +If any provision of the Licence is invalid or unenforceable under applicable law, this will not affect the validity or +enforceability of the Licence as a whole. Such provision will be construed or reformed so as necessary to make it valid +and enforceable. +The European Commission may publish other linguistic versions or new versions of this Licence or updated versions of +the Appendix, so far this is required and reasonable, without reducing the scope of the rights granted by the Licence. +New versions of the Licence will be published with a unique version number. +All linguistic versions of this Licence, approved by the European Commission, have identical value. Parties can take +advantage of the linguistic version of their choice. + +14.Jurisdiction +Without prejudice to specific agreement between parties, +— any litigation resulting from the interpretation of this License, arising between the European Union institutions, +bodies, offices or agencies, as a Licensor, and any Licensee, will be subject to the jurisdiction of the Court of Justice +of the European Union, as laid down in article 272 of the Treaty on the Functioning of the European Union, +— any litigation arising between other parties and resulting from the interpretation of this License, will be subject to +the exclusive jurisdiction of the competent court where the Licensor resides or conducts its primary business. + +15.Applicable Law +Without prejudice to specific agreement between parties, +— this Licence shall be governed by the law of the European Union Member State where the Licensor has his seat, +resides or has his registered office, +— this licence shall be governed by Belgian law if the Licensor has no seat, residence or registered office inside +a European Union Member State. + + + Appendix + +‘Compatible Licences’ according to Article 5 EUPL are: +— GNU General Public License (GPL) v. 2, v. 3 +— GNU Affero General Public License (AGPL) v. 3 +— Open Software License (OSL) v. 2.1, v. 3.0 +— Eclipse Public License (EPL) v. 1.0 +— CeCILL v. 2.0, v. 2.1 +— Mozilla Public Licence (MPL) v. 2 +— GNU Lesser General Public Licence (LGPL) v. 2.1, v. 3 +— Creative Commons Attribution-ShareAlike v. 3.0 Unported (CC BY-SA 3.0) for works other than software +— European Union Public Licence (EUPL) v. 1.1, v. 1.2 +— Québec Free and Open-Source Licence — Reciprocity (LiLiQ-R) or Strong Reciprocity (LiLiQ-R+). + +The European Commission may update this Appendix to later versions of the above licences without producing +a new version of the EUPL, as long as they provide the rights granted in Article 2 of this Licence and protect the +covered Source Code from exclusive appropriation. +All other changes or additions to this Appendix require the production of a new EUPL version. diff --git a/LICENSE-APACHE-2.0.txt b/LICENSE-APACHE-2.0.txt new file mode 100644 index 0000000..b1a313f --- /dev/null +++ b/LICENSE-APACHE-2.0.txt @@ -0,0 +1,201 @@ + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

It leverages the power of the Nexus toolkit and the clarity of KDL recipes to solve the core challenges of modern software development. + +## **🦅 The Vision: Solving the "It Works on My Machine" Problem, For Good** + +In today's development landscape, a git clone is not enough. Developers working on lightweight clients like a MacBook Air or a Samsung DeX setup need a way to bootstrap a complete, consistent, and ready-to-code environment without manual configuration. Existing solutions like VS Code Devcontainers, Gitpod, and Codespaces have paved the way, but they represent a compromise between convenience, reproducibility, and security. + +The Nexus toolkit introduces **devcell**, a new target for the nexus command that provides a quantum leap forward. It embraces the open devcontainer.json standard for familiarity while layering on a set of powerful, philosophically consistent features that are unique to the Nexus ecosystem: + +1. **Verifiable Reproducibility:** We move beyond "best-effort" reproducibility. A devcell can be compiled into a **Verifiable Devcell Artifact (VDA)**, a cryptographically signed manifest that guarantees an environment is bit-for-bit identical, every time, on every machine. This is a core tenet of our **Anomaly Commercial Use License (ACUL)**, transformed into a powerful technical feature. +2. **Secure-by-Default Secrets Management:** We address a critical weakness in the current ecosystem. devcell integrates with a platform-native secrets vault, injecting credentials as temporary files by default—not as leaky environment variables. Security is the baseline, not an afterthought. +3. **A Sustainable Ecosystem:** Our dual-license model (permissive MIT for open-source, ACUL for commercial use) creates a "flywheel" that funds the Nexus Foundation, ensuring the long-term health and innovation of the project. + +## **📐 How It Works: Familiar Standards, Superior Engine** + +The devcell architecture is designed to be both familiar and revolutionary. + +### **1\. The Manifest: Full devcontainer.json Compatibility** + +\[cite\_start\]We embrace the open **Development Container Specification** as our foundation\[cite: 1, 2\]. There is no proprietary lock-in. \[cite\_start\]Any project already using a devcontainer.json file for VS Code or GitHub Codespaces is ready for devcell\[cite: 5\]. + +The nexus runtime will parse and honor all standard properties, including: + +* \[cite\_start\]image or build for defining the base environment\[cite: 5\]. +* \[cite\_start\]features for declaratively adding tools and runtimes from OCI registries\[cite: 7\]. +* \[cite\_start\]postCreateCommand and other lifecycle hooks for automating setup\[cite: 1\]. + +### **2\. The Nexus Enhancement: Verifiable Reproducibility & Security** + +The true power of devcell is unlocked through a Nexus-specific block within the devcontainer.json customizations section. + +"customizations": { + "nexus": { + "reproducibility": { + "level": "strict", + "logPath": ".nexus/build.npk" + }, + "secrets": { + "DATABASE\_PASSWORD": {}, + "LEGACY\_API\_KEY": { "env": "API\_KEY\_VAR" } + } + } +} + +* **reproducibility**: When set to strict, the nexus CLI initiates a specialized build process. It deterministically pins all dependencies (e.g., resolving apt-get install curl to a specific version like curl=7.81.0-1ubuntu1.15), logs every step into the .npk file, and generates a cryptographically signed **Verifiable Devcell Artifact (VDA)**. This transforms the ACUL license requirement for reproducibility into a tangible, verifiable feature, inspired by the power of Nix. +* **secrets**: This block defines which secrets from the Nexus platform vault should be injected. + * DATABASE\_PASSWORD: Injected securely as a file at /var/run/secrets/nexus/DATABASE\_PASSWORD by default. + * LEGACY\_API\_KEY: Injected as both a file and, via an explicit opt-in, as an environment variable for legacy compatibility. This "secure by default" posture is a vast improvement over the standard, environment-variable-first approach. + +### **3\. The CLI: A Simple, Powerful Workflow** + +The nexus target devcell command provides the primary interface for managing the environment lifecycle. + +\# Bring up the environment defined in the local devcontainer.json +nexus target devcell up + +\# Tear down the environment +nexus target devcell down + +\# Perform a fresh build, ensuring a clean state +nexus target devcell rebuild + +\# For commercial use, publish a verifiable artifact +nexus target devcell publish \--commercial + +## **競争力分析: Why devcell Wins** + +devcell is not designed to be just another CDE.

It will include the core nexus target devcell up/down commands, full support for the standard devcontainer.json specification, and the initial version of our secure, file-based secrets vault. All components will be released under the permissive MIT license to build a strong user base. +* Phase 2: Beta + The Beta release will introduce our key differentiators. We will implement the Verifiable Reproducibility engine, expand the secrets vault with project/organization scopes, and integrate the CLI with the Nexus Foundation membership API. A cohort of commercial partners will be onboarded to test the end-to-end ACUL workflow. +* Phase 3: General Availability (GA) + The GA release will mark the full public launch. We will enable hard enforcement for ACUL compliance on the publish \--commercial command, polish the user experience, and release official CI/CD integrations for platforms like GitHub Actions and GitLab CI. + +## **🎖️ Conclusion: The Future of Development Environments** + +nexus target devcell is more than just a new feature; it is a strategic initiative to define the future of development environments. It provides a holistic platform that delivers the convenience of containers, the determinism of functional systems, and a security model that is second to none. + +By integrating our unique dual-license business model directly into the product's workflow, devcell creates a powerful flywheel that provides immense value to both open-source and commercial developers while securing the long-term financial health and innovative capacity of the entire NexusOS Project. + +We are not just building another CDE.

They're designed to work together. Use packages for system tools and Nippels for isolated apps. + +### Q: Do Nippels slow down my applications? +**A:** No! Nippels add < 10ms startup overhead and zero memory overhead. They're faster than Flatpak or Docker. + +### Q: Can I backup my Nippels? +**A:** Yes! In portable mode, just copy `~/.nip/cells//` and you're done. The entire environment is self-contained. + +### Q: Do Nippels work with all applications? +**A:** Yes! Any Linux application works. GUI apps get perfect desktop integration (themes, fonts, clipboard). + +### Q: Can I share files between Nippels? +**A:** By design, Nippels are isolated. But you can mount shared directories if needed (with appropriate permissions). + +### Q: Are Nippels secure? +**A:** Yes! They use Linux kernel namespaces for isolation. Strict mode provides strong security boundaries. + +### Q: How much disk space do Nippels use? +**A:** Very little! Files are deduplicated via CAS.

The Core Principle: Immutability as a Compilation Target** + +The fundamental design philosophy of NexusOS treats immutability not as a feature to be added, but as an inherent property of the system compilation process. Rather than retrofitting atomicity onto an existing mutable system, NexusOS produces immutable systems by design through its build orchestration. + +An "Immutable NexusOS" deployment is the artifact produced when the nexus build orchestrator compiles a system definition (`system.nexus.nim`) with the explicit intent of creating a hermetic, read-only, and cryptographically verifiable system image. This approach eliminates dependency on external tools like rpm-ostree, as the entire stack—from NimPak package management to Generation lifecycle management—is architected around immutability from the ground up. + +## **2\. The Pillars of NexusOS Immutability** + +The immutable system architecture is built upon four foundational pillars: + +### **Pillar 1: The Declarative Single Source of Truth** + +Every aspect of the system—kernel parameters, installed packages, configuration files, and system policies—is declared in a single, version-controlled `system.nexus.nim` file. This eliminates hidden state and prevents manual, out-of-band modifications that could compromise system integrity or reproducibility. + +### **Pillar 2: The nexus Compiler as System Orchestrator** + +The `nexus` command functions as a system compiler. It parses the declarative system definition and executes a deterministic build process that produces a complete, bootable system image. A critical step in this compilation process is setting the **read-only flag for the root filesystem**, ensuring that the deployed system cannot be modified at runtime. + +### **Pillar 3: The GoboLinux Architecture for Physical Separation** + +The root filesystem (`/`) of an immutable NexusOS deployment consists almost exclusively of **symlinks** pointing to specific, versioned, read-only directories under `/Programs`. This architecture provides: + +* **Version isolation:** `/usr/bin/nginx` → `/Programs/Nginx/1.2.3/bin/nginx` +* **Library pinning:** `/lib/libssl.so` → `/Programs/OpenSSL/3.0.1/lib/libssl.so` + +The base system is a curated collection of read-only symbolic links. Security hardening measures are essential: + +- Use of relative symlinks where possible +- Rejection of path traversal attempts +- Optional `noexec,nodev` mount flags for `/Programs` +- Symlink ownership and permission validation + +### **Pillar 4: Atomic Updates via Symlink Transactions** + +System updates never modify files in the running system. The update process follows these steps: + +1. **Build Phase:** The nexus updater constructs the new system Generation in an isolated temporary area, creating new versioned directories under `/Programs` (e.g., `/Programs/Nginx/1.2.4/`) +2. **Verification Phase:** The build is validated for completeness and integrity before deployment +3. **Atomic Transaction:** A single, atomic operation re-points all root filesystem symlinks to the new program versions +4. **Boot Manager Update:** NexusBoot is updated to offer the new Generation as a boot option + +This process is inherently atomic—either the entire transaction succeeds, or the system remains in its previous state. There are no partial updates. + +## **3\. User Interaction Model in Immutable Deployments** + +In an immutable NexusOS deployment, user freedom is not restricted but rather **channeled into designated, safe areas**. This enforces operational discipline while maintaining system stability. + +### **Package Installation Behavior** + +**Attempting global installation:** +```bash +$ nip install htop +Error: System is immutable. To install for your user only, specify a target cell: + nip install --cell=my-tools htop +``` + +The `nip` client detects write permission restrictions on `/Programs` and provides clear guidance. + +### **NexusCell Enforcement** + +The system enforces isolation by requiring users to explicitly declare their intent to install software into their own isolated NexusCell. This ensures: + +- The base system remains untouched and guaranteed stable +- User-installed software is isolated and does not affect system-level operations +- Troubleshooting is simplified by clear separation of system and user software + +### **System Modifications via Declarative Overlays** + +Administrators requiring base system changes do not execute imperative commands. Instead, they: + +1. Write a declarative **Overlay Fragment** specifying the desired changes +2. Submit the fragment to the nexus system for compilation +3. Allow nexus to compile a new, official Generation +4. Deploy the new Generation to the fleet through standard update mechanisms + +This workflow ensures all system changes are: +- Version controlled +- Auditable +- Reproducible +- Testable before deployment + +## **4\. Declarative System Definition** + +The following example demonstrates how an immutable system is declared in a Fragment file: + +```nim +# secure_appliance.fragment.nim + +# Define a system artifact named "secure-medical-terminal" +systemArtifact "secure-medical-terminal" do + version "2025.07.1" + + # Immutability configuration + target do + osType "immutable" + rootFs "read-only" + bootloader "NexusBoot" + defaultGeneration true + + # System composition + baseStream "nexusos-lts-2025.04" + installPackages "medical-viewer-app", "secure-browser" + + # User policy enforcement + userPolicy do + allowNipCells true # Users may install software in their cells + globalPackageInstall "denied" # System-level 'nip install' is blocked +``` + +## **5\. Operational Advantages** + +NexusOS achieves immutability through architectural design rather than external tooling. This provides several operational benefits: + +### **Compared to Traditional Approaches** + +- **rpm-ostree, Valve SteamOS:** Attempt to retrofit immutability onto existing mutable distributions +- **NexusOS:** Immutability is a compilation target, not a post-processing step + +### **Key Benefits for System Administrators** + +1. **Predictable State:** Every deployed system is bit-for-bit reproducible from its declaration +2. **Atomic Rollback:** Failed updates can be instantly reverted by selecting a previous Generation at boot +3. **Fleet Consistency:** All systems built from the same declaration are identical +4. **Simplified Troubleshooting:** Clear separation between system and user modifications +5. **Security Hardening:** Read-only root filesystem prevents entire classes of attacks +6. **Compliance:** Immutable systems simplify audit and compliance requirements + +--- + +## **Conclusion** + +The ability to deliver atomic, immutable systems is not a feature bolted onto NexusOS—it is the logical consequence of fundamental architectural decisions. By treating system deployment as a compilation process with immutability as a first-class property, NexusOS provides system administrators with unprecedented control, predictability, and operational safety. diff --git a/docs/automatic-updates.md b/docs/automatic-updates.md new file mode 100644 index 0000000..2277221 --- /dev/null +++ b/docs/automatic-updates.md @@ -0,0 +1,635 @@ +# Automatic Updates Guide + +## Overview + +NIP's automatic update system keeps your recipes, build tools, and NIP itself up to date with minimal user intervention.

It merges the initial project plan with a content-addressed, Merkle-based architecture for maximum efficiency, verifiability, and reproducibility. + +--- + +## 1. Core Principles + +- **Content-Addressable:** All data is stored based on its content hash, providing automatic deduplication. +- **Cryptographically Verifiable:** The entire system state can be verified with a single cryptographic hash. +- **Immutable & Atomic:** Installations and updates are atomic operations, ensuring system consistency. +- **Declarative:** The system state is defined by declarative manifest files. + +### 1.1. Trust and Authenticity + +To ensure not just integrity but also authenticity, `nip` incorporates a trust layer based on Ed25519 signatures. + +- **Manifest Signatures:** Each `.npk` manifest can be signed using Ed25519 keys (e.g., OpenSSH keys). Signatures can be detached or inline within the manifest. This allows verification of the package's origin. Multiple signatures (e.g., personal, CI, Foundation) are supported. +- **Root-of-Trust for `nip.lock`:** The `nip.lock` file, representing a complete system generation, can be signed. A single signature over the lockfile transforms the Merkle root into a tamper-evident release artifact. +- **Key Management:** Support for `keyid`, `created`, and `expires` metadata for keys facilitates revocation and rotation without requiring every package to be rebuilt. This lays the groundwork for future TUF-style metadata integration. + +## 2. Hashing Algorithms + +- **Cryptographic Hashing:** The default hash algorithm is **BLAKE2b-512** until BLAKE3 becomes available in Nimble. The digest is encoded as **Multihash** (varint ``) to ensure future-proofing, allowing for easy transitions to other algorithms like BLAKE3, SHA-512 or KangarooTwelve without redesigning the CAS. +- **Non-Cryptographic Hashing:** **SipHash** is recommended for internal data structures. + +## 3. Storage Architecture + +### 3.1. The Content-Addressable Store (CAS) + +The CAS is the canonical source of all file data. + +- **Locations:** `~/.nip/cas/` (user) and `/var/lib/nip/cas/` (system). +- **Compression:** To conserve disk space, objects are stored compressed by default using `zstd`. However, the canonical hash of an object is **always the hash of its uncompressed content** using the configured algorithm (BLAKE2b-512 by default). Integrity is always verified against the true data. This behavior can be configured in `nip.conf` (e.g., `cas.compress = true`, `cas.compression_level = 19`). +- **Structure:** Objects are stored by their multihash (hex-encoded), sharded by the first two hex characters (e.g., `cas/ab/cdef1234...`). For large fleets, sharding can extend to more levels (e.g., `cas/ab/cd/efgh...` for 4-level fan-out after 16k objects). +- **Garbage Collection:** A **reference-counted garbage collector** (`nip gc`) reclaims space by scanning every reachable manifest hash in all live `nip.lock` files (system + user cells) and marking CAS objects reachable via those manifests. Unmarked blobs are then deleted. Optionally, **"pin sets"** (named live roots, à la Docker) can be added to prevent specific objects from being collected. + +### 3.2. The Manifest Store + +- **Locations:** `~/.nip/manifests/` (user) and `/var/lib/nip/manifests/` (system). +- **Structure:** Stores `.npk` manifest files, whose own BLAKE3 hashes serve as their unique IDs. + +## 4. The `.npk` Manifest Format + +A single, self-contained KDL document. Its BLAKE3 hash is the package's unique identifier. + +### 4.1. KDL Schema for `.npk` + +```kdl +package "htop" { + version "3.3.0" + description "Interactive process viewer" + channels { stable, testing } # Lets one manifest live in multiple Streams without duplication. + + source "pacman" { /* ... */ } + dependencies { /* ... */ } + + build { + system "x86_64-linux" + compiler "nim-2.2.4" + env_hash "blake3-d34db33f..." # Stores the deterministic build fingerprint—needed for exact rebuilds & `nip verify --rebuild`. + } + + snapshots { + created "2025-07-16T20:00:00Z" # Easy human audit; ISO 8601 timestamp. + } + + files { + file "/Programs/Htop/3.3.0/bin/htop" "blake3-f4e5d6..." "755" + file "/Programs/Htop/3.3.0/share/man/man1/htop.1.gz" "blake3-a9b8c7..." "644" + } + + artifacts { /* ... */ } + services { + systemd "htop.service" "blake3-unit..." # For packages that ship systemd units. + } + signatures { + # Ed25519 signatures on each .npk manifest (detached, or inline `signature "ed25519" ""`). + # Supports multiple keys (personal, CI, Foundation). + # Record `keyid`, `created`, `expires`. + } +} +``` + +## 5. The System Lockfile: `nip.lock` + +The **System Generation Manifest**, defining the complete state of installed packages. + +### 5.1. KDL Schema for `nip.lock` + +```kdl +lockfile_version 1.2 + +generation { + id "blake3-d34db33f..." # The hash of this file. + created "2025-07-16T20:05:17Z" # ISO 8601 timestamp. + previous "blake3-abcdef..." # Hash of the previous generation's lockfile, forming a hash-chained log. +} + +packages { + package "htop-3.3.0.npk" "blake3-htophash..." + package "ncurses-6.4.npk" "blake3-ncurseshash..." +} + +signature "ed25519" "" # Root-of-trust for `nip.lock` (system generation). `nip sign lock --key ~/.ssh/nip_ed25519` +``` + +## 6. The Installation Filesystem + +### 6.1. GoboLinux-style Hierarchy (`/Programs`) + +A human-readable hierarchy of symlinks pointing to the CAS, providing a view of an immutable backend. + +### 6.2. `PATH` Management via Active Index + +To expose executables to the user's shell, `nip` uses an "Active Index" directory. This is a single, stable location the user adds to their `PATH`. + +- **System-wide:** `/System/Index/bin` +- **User-specific:** `~/.nip/profile/bin` + +When a new generation is activated via `nip switch`, `nip` atomically repopulates this directory with symlinks to the executables of the new generation. This provides fast shell startup and race-free activation. + +## 7. Cross-Platform Compatibility & Security + +### 7.1. Path Separators + +- **Manifests must use POSIX forward slashes (`/`) for all paths.** This is the canonical format. +- The `nip` client is responsible for translating paths to the native format (e.g., `\` on Windows) at runtime. +- Manifests containing backslashes will be rejected by `nip verify`. + +### 7.2. Symlink Security & Hardening + +- Only **relative symlinks** are created and verified before writing to prevent filesystem escapes. +- Manifests attempting path traversals (e.g., `../../etc/passwd`) are rejected during verification. +- Optionally, `/Programs` can be mounted as `noexec,nodev` and rely on a "programs overlay" bind mount that flips execute bits only for whitelisted directories, enhancing security. +- On older Windows versions, `nip` will fall back to using junctions or hard-links if developer-mode symlinks are unavailable. + +## 8. Remote Operations & Caching + +`nip` supports fetching missing objects from remote binary caches (e.g., a static HTTP server or S3 bucket). Since objects are content-addressed, a remote cache is a simple key-value store, mirroring Nix's binary cache feature. + +- **`nip remote add `:** Adds a remote cache (e.g., `nip remote add origin https://cache.nexushub.io`). Missing objects/manifests can then be fetched via HTTP range GET. +- **`nip remote push `:** Uploads missing CAS blobs + manifest to the remote cache, returning content URIs. +- **`nip remote serve --path /var/lib/nip`:** Starts a read-only cache server, trivial for air-gapped labs. + +## 9. Advanced CAS Concepts: Delta & Chunk-level Deduplication (Phase 2) + +To further optimize bandwidth and storage, `nip` is designed to support a future phase of delta and chunk-level deduplication. + +- **Fixed-size "Merkle-chunk" layer:** Large binaries often compress poorly across versions, but chunk hashes can deduplicate a significant portion (e.g., ~90% of same-version-family kernels). +- **Implementation:** This would involve a `files` node in the `.npk` manifest referencing a list of chunk hashes instead of a single file hash, allowing for efficient storage and transfer of only changed chunks. + +## 10. Proposed CLI Tooling + +- **`nip cat `:** Dumps a CAS blob to stdout. Great for debugging. Use `--raw` flag for uncompressed stream. +- **`nip fsck`:** Verifies that every symlink in `/Programs` targets a valid CAS object referenced in *some* manifest; repairs stray links. +- **`nip doctor`:** Runs `fsck`, `gc --dry-run`, and prints actionable suggestions for system health. +- **`nip diff `:** Compares two lockfiles; outputs added/removed/changed manifests (with semantic version bump hints). diff --git a/docs/gentoo-nix-guide.md b/docs/gentoo-nix-guide.md new file mode 100644 index 0000000..88ea872 --- /dev/null +++ b/docs/gentoo-nix-guide.md @@ -0,0 +1,673 @@ +# Using Nix Packages on Gentoo + +## Overview + +This guide shows Gentoo users how to use NIP to access Nix's vast package repository while keeping their Gentoo system intact.

Hier ist, warum dieser Ansatz architektonisch so stark ist: + +1. **Pragmatismus am Start (`systemd` für die LiveCD):** Wir erkennen an, dass das "perfekte" System nicht das "sofortige" System blockieren darf. Indem wir für die anfängliche Arbeitsumgebung auf `systemd` setzen, kaufen wir uns Geschwindigkeit und eliminieren eine massive Hürde, die uns monatelang aufhalten könnte. Wir können uns sofort auf unsere Kerninnovationen (`nip`, `nexus`, `NimPak`) konzentrieren. + +2. **Philosophische Klarheit im Ziel (`dinit`, `runit`, `s6`):** Wir halten an unserer Vision fest. Das Endziel ist ein GNU-freies, schlankes und sauberes System. Deine Auswahl deckt die Anwendungsfälle perfekt ab: + * **`dinit` für Server:** Der pragmatische, moderne Mittelweg. Mächtig genug für Abhängigkeiten, aber schlank und sauber. Das ideale Standard-Init für die meisten NexusOS-Server-Deployments. + * **`runit` für Embedded:** Die minimalistischste, robusteste Wahl. Wenn jeder CPU-Zyklus und jedes Byte zählt und die Service-Struktur einfach ist, ist `runit` unschlagbar. + * **`s6-rc` für komplexe Setups:** Für den "Mastery Mode"-Anwender, der die absolute Kontrolle und Modularität eines vollständigen Tool-Ökosystems benötigt. + +3. **Es stärkt die Vision von "Nexus as a Compiler":** Diese Entscheidung passt perfekt in unsere übergeordnete Vision. Das Init-System wird zu einem weiteren `target`-Parameter im Build-Prozess. Der Benutzer deklariert sein Ziel, und der `nexus`-Compiler wählt das passende Fundament aus: + * `nexus build my-appliance --target=embedded` → verwendet `runit`. + * `nexus build my-api-server --target=server` → verwendet `dinit`. + * `nexus build my-complex-service-mesh --target=enterprise` → verwendet `s6-rc`. + +Damit haben wir eine klare Marschrichtung für die Systeminitialisierung. Die Entscheidung ist getroffen. Der Plan, mit einer `systemd`-basierten ArchISO zu beginnen, ist der pragmatischste und schnellste Weg nach vorn. \ No newline at end of file diff --git a/docs/json-output.md b/docs/json-output.md new file mode 100644 index 0000000..c07178d --- /dev/null +++ b/docs/json-output.md @@ -0,0 +1,134 @@ +# JSON Output Support + +## Overview + +NIP provides comprehensive machine-readable output in multiple structured formats (JSON, YAML, KDL) for automation, tooling integration, and AI-friendly interfaces. + +## Output Formats + +### JSON Output +```bash +nip search firefox --json +nip list --json +nip show firefox --json +``` + +### YAML Output +```bash +nip search firefox --yaml +nip list --yaml +nip show firefox --yaml +``` + +### KDL Output +```bash +nip search firefox --kdl +nip list --kdl +nip show firefox --kdl +``` + +## JSON Schema + +### Search Results +```json +{ + "query": "firefox", + "results": [ + { + "name": "firefox", + "version": "118.0", + "description": "Mozilla Firefox web browser", + "stream": "stable", + "repository": "nexusos-stable", + "install_status": "NotInstalled", + "integrity_status": "Unknown", + "size": 250000000, + "install_date": null, + "variants": [ + { + "cid": "blake3-F21194C0A7BC", + "cas_path": "/Programs/firefox/118.0-F21194C0A7BC/", + "features": {}, + "build_flags": {}, + "toolchain": "gcc-13", + "target": "x86_64-linux-gnu", + "integrity_status": "Unknown" + } + ], + "tags": ["browser", "gui"] + } + ], + "total_found": 1, + "cas_enabled": true, + "variant_fingerprints": true +} +``` + +### Package Information +```json +{ + "name": "firefox", + "version": "3.2.2", + "description": "Interactive process viewer for Unix systems", + "homepage": "https://htop.dev", + "license": "GPL-2.0", + "stream": "stable", + "architecture": "x86_64", + "installed": true, + "install_date": "2025-08-05T10:30:00Z", + "size": { + "installed": 2048576, + "download": 512000 + }, + "dependencies": [ + { + "name": "libc", + "version": ">=2.17", + "type": "runtime" + } + ], + "files": [ + "/System/Index/bin/htop" + ], + "build_hash": "blake3-abc123def456...", + "acul_compliant": true +} +``` + +## Integration Examples + +### Shell Scripting +```bash +# Get package count +PACKAGE_COUNT=$(nip list --json | jq '.total') + +# Check if package is installed +IS_INSTALLED=$(nip show firefox --json | jq '.installed') + +# Get CAS path +CAS_PATH=$(nip show firefox --json | jq -r '.variants[0].cas_path') +``` + +### Python Integration +```python +import subprocess +import json + +def get_package_info(package_name): + result = subprocess.run(['nip', 'show', package_name, '--json'], + capture_output=True, text=True) + return json.loads(result.stdout) + +package = get_package_info('firefox') +print(f"Package: {package['name']} v{package['version']}") +print(f"CAS Path: {package['variants'][0]['cas_path']}") +``` + +## Use Cases + +- **CI/CD Integration**: Automated package management in pipelines +- **Infrastructure as Code**: Declarative system configuration +- **Monitoring**: Package status and integrity monitoring +- **AI Integration**: Machine-readable package information +- **Custom Tooling**: Building package management tools +- **Reporting**: System inventory and compliance reporting \ No newline at end of file diff --git a/docs/learning-nim.md b/docs/learning-nim.md new file mode 100644 index 0000000..111357e --- /dev/null +++ b/docs/learning-nim.md @@ -0,0 +1,6 @@ +# Learning Nim for NexusOS +## Session 1: osproc and Types (17 July 2025) +- Learned `osproc.execCmd` for running external commands. +- Explored `object`, `enum`, `seq` for package data. +- Created `osproc_example.nim` and `types_example.nim`. +- Key takeaway: Nim can control system tools and structure data cleanly. diff --git a/docs/license_json_examples.md b/docs/license_json_examples.md new file mode 100644 index 0000000..cd3078f --- /dev/null +++ b/docs/license_json_examples.md @@ -0,0 +1,32 @@ +### **Example 1: Core Tooling (nexus, nip)** + +This file declares that the project is available under the dual-license scheme.

| ------------------------------------------------------------------------------------------------- | ----------------- | -------------------------- | +| **Source Recipes** (Fragments, purely declarative) | `.npr` (*Nexus Package Recipe*) | **KDL** metadata describing build instructions; minimal logs; no binaries. | None (plain text) | Signed metadata (Ed25519) | +| **Compiled Binary

configurations in KDL | None (plain text) | Signed metadata (Ed25519) | + +--- + +## 🧠 **Reasoning & Justification** + +### Why `.npk.zst` explicitly? + +* Aligns clearly with **Arch Linux conventions**, explicitly indicating Zstandard compression. +* Immediately recognizable to sysadmins familiar with modern Linux distributions. +* Avoids ambiguity and clearly communicates the compression method at a glance. + +**Example:** + +``` +neofetch-7.1.0.npk.zst +``` + +### Why `.npr` (recipe format)? + +* Clearly distinguishes source-level recipes (KDL) from binary packages. +* Explicitly uncompressed for easy human readability, version control (Git-friendly). + +**Example:** + +``` +neofetch-7.1.0.npr +``` + +### Why `.nca` (CAS archives)? + +* Clearly indicates the file is part of NexusOS’s content-addressable storage. +* Binary blobs optimized for high deduplication rates and rapid verification. + +### Why `.nss.zst` (system snapshots)? + +* Identifies clearly as a snapshot artifact for reproducible environments. +* Explicit Zstandard compression for storage efficiency and decompression speed. + +### Why `.nof` (Overlay fragments)? + +* Short, clear, distinctive naming. +* Explicitly uncompressed, easily readable and editable in immutable configuration management workflows. + +--- + +## 🔐 **Future-Proofing & Quantum-Resilience** + +To ensure long-term future-proofing (quantum-resistant hashing/signatures): + +* **Short Term** (now → 2026): + + * Standardize **BLAKE3** hashing for all integrity checks (currently strongest practical hash). + * **Ed25519** for digital signatures (fast, secure, widely used). + +* **Medium Term** (2026+ → quantum era): + + * Prepare a transparent upgrade path to quantum-resistant algorithms like **Dilithium** (post-quantum signatures) or similar NIST PQC standards. + * Package format includes a “version field” in KDL metadata, explicitly stating cryptographic algorithms used for hashing and signing, allowing graceful transitions without format breaks. + +Example metadata snippet (future-proof): + +```kdl +package "neofetch" { + version "7.1.0" + + integrity { + hash "blake3-abcdef1234567890..." + signature "ed25519-abcdef1234567890..." + algorithm "BLAKE3" + signingAlgorithm "Ed25519" + } +} +``` + +When transitioning: + +```kdl +integrity { + hash "sha3-512-abcdef1234567890..." + signature "dilithium-abcdef1234567890..." + algorithm "SHA3-512" + signingAlgorithm "Dilithium" +} +``` + +This approach ensures clarity, auditability, and forward compatibility. + +--- + +## 📌 **Final Recommended Structure** + +A clearly summarized and recommended standard moving forward: + +| Type | Extension | Compression | Integrity | Quantum-Ready | +| ---------------------- | ---------- | ------------- | ------------------------- | --------------------------- | +| **Package Recipes** | `.npr` | None | Signed metadata (Ed25519) | ✅ Yes (metadata upgradable) | +| **Binary Packages** |

Nim-Powered Core & Hybrid DSL** + +* A robust, statically-typed foundation built in Nim, ensuring performance and reliability. +* **Hybrid Recipe Approach:** + * An elegant, high-level Nim-based Domain Specific Language (DSL) leveraging metaprogramming for concise, powerful, and type-safe package definitions and system configurations ("Mastery Mode"). + * A simplified, declarative recipe format (e.g., YAML-like or a restricted Nim syntax, inspired by AerynOS "stones") for common use cases and as a target for imported recipes. This "Easy Mode" format translates internally to the full Nim DSL, ensuring clarity and human-readability for basic package maintenance. +* **Direct NimScripting Capability:** Alongside the DSL, NexusOS provides the ability to use NimScript directly for highly sophisticated or bespoke package and system building tasks. This offers maximum flexibility and an immediate power ramp, especially during early development phases. + +### **2\. Universal Recipe Ingestion & Translation** + +* Strategic ingestion and translation of package definitions from established ecosystems, primarily **Nixpkgs** (treating .nix as a declarative "Kalkül") and **Arch PKGBUILDs**. +* Ensures immediate, vast software availability, bootstrapping a rich ecosystem from day one. + +### **3\. GoboLinux-Inspired Filesystem Model** + +* Intuitive, versioned application directories (e.g., /Programs/AppName/Version), enhancing clarity and simplifying manual inspection. +* Effortless activation and rollback of application versions via managed Current symlinks. + +### **4\. Atomic Transactions, System Generations & Bootloader Integration** + +* Default transactional integrity for all system modifications, creating immutable "generations" (inspired by NixOS/Guix/AerynOS). +* Guarantees system consistency: operations complete fully or not at all. +* **Bootloader Integration:** Native support for Limine to list and boot into previous system generations, enabling seamless A/B style rollbacks at boot time for maximum system recovery capability. +* Pragmatic overrides (e.g., --allow-partial-update) for expert-driven, targeted operations. + +### **5\. Sophisticated Version, Channel & Retention Management** + +* Native support for distinct software channels (stable, LTS, testing, git-dev). +* User-configurable, fine-grained retention policies (defined in the Nim DSL) for managing package versions and disk space intelligently. + +### **6\. Programmable, Guix-Inspired Build System with Type-Safe "Macros"** + +* Moving beyond shell-script dominance, build logic is expressed directly in typed Nim. +* Define reusable "build systems" (for Autotools, CMake, Meson, Cargo etc.) as Nim modules. +* **Type-Safe Build Templates (Nim Metaprogramming):** Instead of simple text-based macros (like AerynOS's %make), NexusOS will utilize Nim's templates and macros to create structured, type-safe, and highly maintainable build abstractions. This captures the simplicity and standardization benefits while adding compile-time checking and greater extensibility. + * Example (Conceptual Nim DSL): + buildPackage("zlib", "1.3.1"): + source("https://zlib.net/zlib-1.3.1.tar.gz", sha256 = "...") + useCMake(opts = ["-DBUILD_TESTING=OFF"]) // Type-safe template + +* Offers deep customization and control akin to Guix, but with Nim's paradigms. + +## + +## + +## **🛠️ Core Engine Architecture: Leveraging Nim's Advanced Capabilities** + +The choice of Nim as the foundational language for NexusOS is a deliberate, strategic decision rooted in its unique and powerful capabilities. The nexus and nip tools are not simple scripts; they are sophisticated, high-performance pieces of system infrastructure. Their architecture is designed to leverage Nim's most advanced features to deliver deterministic performance and massive concurrency. + +### **1\. Memory Management: Determinism via ARC/ORC** + +This choice is about performance predictability and suitability for systems programming. + +* Garbage Collection (GC): The default, traditional GC prioritizes developer convenience. While robust, it can introduce non-deterministic "stop-the-world" pauses to clean up memory. For a simple command-line tool that runs and exits, this is often acceptable. For a long-running daemon or a core system utility where responsiveness is key, these pauses are a liability. +* ARC/ORC (Automatic Reference Counting / Ownership): This is our choice for NexusOS. It is about deterministic performance. Memory is freed the instant it is no longer referenced, similar to the RAII model in C++ or Rust's ownership system, but without the manual memory management or the complexity of a borrow checker. This eliminates unpredictable pauses, resulting in smoother, more consistent performance. The trade-off—a tiny, constant overhead for updating reference counts and the need to manually break rare reference cycles—is a worthwhile price for the robustness and predictability required of core system infrastructure. + +Verdict for NexusOS: We will build with ARC/ORC from the start (--gc:orc). A package manager and system orchestrator must be as predictable and real-time as possible. The deterministic nature of ARC/ORC is a perfect match for the low-level, high-performance tasks we will implement, such as file hashing, process management, and data deduplication. + +### + +### **2\. Concurrency: A Hybrid Model for Maximum Throughput** + +This is not an "either/or" question. The correct architecture uses both of Nim's concurrency models strategically for different tasks. + +* async is for I/O-bound work. + * Use Case: Fetching dozens of source tarballs from the network, downloading pre-built .npk binaries, checking hashes of large files on disk. + * Why: These tasks spend most of their time *waiting* for the network or disk. async allows a single OS thread to efficiently juggle hundreds of these waiting operations without the heavy overhead of creating a dedicated thread for each one. It's about maximizing throughput when the CPU is not the bottleneck. +* spawn is for CPU-bound work. + * Use Case: Compiling source code (e.g., running GCC on a large C++ project), compressing final .npk packages. + * Why: These tasks will max out a CPU core. Running them in an async context would block the entire event loop, freezing all other I/O operations. spawn creates a true OS-level thread that the kernel can schedule on a separate CPU core. This allows for true parallelism, enabling us to build multiple packages simultaneously and fully utilize a multi-core processor (the equivalent of make -j8). + +### **3\. The Hybrid Architecture in Practice** + +The nexus build orchestrator will be architected as follows: + +1. The Orchestrator (Main Thread using async): The main nexus process runs an async event loop. Its job is to manage the overall workflow. It will parse the dependency graph and use a pool of async workers to fetch all sources and check all hashes concurrently. This phase is all about I/O saturation. +2. The Build Farm (Thread Pool using spawn): Once the sources for a package are ready, the async orchestrator will *not* build it directly. Instead, it will submit a "build job" to a thread pool. This pool will consist of a fixed number of worker threads (e.g., matching the number of CPU cores). Each worker thread will pull a job from the queue, spawn the compilation process, and wait for it to finish. This phase is all about CPU saturation. +3. Deployment (Back to async): Once a build is complete, the worker thread notifies the main orchestrator. The orchestrator can then handle the final deployment—atomically moving the build output to the final GoboLinux-style path—using async file I/O. + +This hybrid model gives us the best of all worlds: maximum I/O throughput for fetching and maximum CPU parallelism for building, all orchestrated cleanly by a single, responsive main process. Nim is exceptionally well-suited for building exactly this kind of sophisticated, multi-paradigm system. + +## + +## **🛠️ Core Engine Architecture: The Nim & Janet Duality** + +NexusOS is built on a principle of architectural integrity: using the right tool for the right job. While the core engine, build orchestrator, and the primary NimPak EDSL are forged in statically-typed Nim for maximum performance and compile-time correctness, we explicitly recognize that not all system logic is static or predictable. For this, we embed Janet—a modern, lightweight, and powerful Lisp—as a first-class citizen within our toolchain from the very beginning. + +Janet serves as the dynamic superglue of the system, the designated successor to fragile and opaque Bash scripts for handling runtime logic. Its role is to manage tasks where the inputs are "fuzzy," unclear, or only available at execution time. This includes fetching dynamic configuration values from a web service, interfacing with non-standard APIs, or executing conditional deployment logic based on live system state that cannot be known at compile time. Unlike shelling out to Bash, the embedded Janet interpreter operates within a controlled context, allowing for structured data exchange (not just text streams) with the core Nim engine and offering a safer, more robust, and debuggable environment for dynamic tasks. + +Nim provides the immutable, verifiable skeleton of the system, while Janet provides the adaptive, intelligent nervous system that allows it to react dynamically. This hybrid approach is not a compromise; it is a deliberate design for creating a system that is both resilient and responsive from day one. + +## + +## **📦 Additional NexusOS Capabilities & Strategic Features** + +The following concepts, inspired by the best aspects of Guix and the potential for Nim-centric packaging (conceptualized as "NimPak"), will significantly enhance NexusOS’s practicality, usability, and user autonomy, offering paths for broader adoption. + +### **1\. Per-User Package Management (Guix-inspired)** + +By default, NexusOS empowers every user on the same machine to independently manage their own software environment without the need for superuser privileges: + +* **User-Level Autonomy:** Users can safely install, upgrade, and manage packages in their own namespace, entirely isolated from the global system and other users. +* **No Root Required for User Packages:** Eliminates security risks and administrative friction associated with global privilege escalations for routine user-specific package operations. +* **Ideal for Multi-User Environments:** Facilitates shared server scenarios, research clusters, and academic environments where user software autonomy and system stability are paramount. + +### **2\. Robust Reproducible Environments (Guix-inspired)** + +NexusOS guarantees reliable reproducibility of computing environments, critical for software developers, researchers, and system administrators alike: + +* **Environment Snapshots:** Easily build and capture complete software environments that include applications, libraries, runtime configurations, and their precise dependencies. +* **Reproduce in Time:** Restore an exact snapshot of your software environment at any future point, ensuring the same outcomes years from now, regardless of intervening system changes. +* **Containers & Virtualization:** Seamlessly create and deploy containerized environments (e.g., OCI images) or VM images based on reproducible NexusOS definitions, significantly enhancing CI/CD pipelines and reproducible research. +* **Example Usage:** + * Build an environment today. + * Reproduce precisely the same environment years from now. + * Guarantee consistent results regardless of system updates or underlying hardware changes. + +### **3\. NimPak — Unified Nim-Centric Package Management (Portable Core)** + +"NimPak" embodies NexusOS’s powerful Nim-native package management vision, designed as a robust, unified API ecosystem within the Nim language, with potential for portability: + +* **Single Language, Infinite Possibilities:** Leverage NimPak’s APIs, including high-level embedded domain-specific languages (EDSLs), to define and manage packages, dependencies, and even whole-system configurations with exceptional clarity and type safety. +* **Potential Integration with Existing Distros:** The core NimPak tooling could be designed to integrate atop any UNIX/Linux distribution without interference or conflicts with the host distribution’s native package manager (APT, DNF, Pacman, etc.). +* **Cross-Distribution Utility:** This portability simplifies adoption by allowing users and developers to experience NimPak's benefits (e.g., for managing development projects or specific application stacks) on existing systems, rather than requiring an immediate wholesale migration to NexusOS. +* **Example Conceptual Usage (NimPak API):** + # Conceptual NimPak definition + definePackage("myapp", "1.0.0"): + source(git = "https://github.com/example/myapp.git", tag = "v1.0.0") + dependencies: + useCMake(["-DBUILD_EXAMPLES=ON"]) # A type-safe build system template + # This definition could potentially be built and managed by NimPak tools + # on Ubuntu, Fedora, Arch, or NexusOS. + +### **🚩 Integration & Advantages of These Additional Features for NexusOS** + +By incorporating these powerful ideas, NexusOS uniquely combines: + +* User-level autonomy and isolated environments (Guix-inspired). +* Deep reproducibility and environmental consistency (Guix-inspired). +* Elegant Nim-native interfaces and a unified tooling vision (NimPak concept). +* A potential path for seamless compatibility and integration of its core package management technology across existing Linux/UNIX distributions. + +This holistic approach enables a gentle, incremental transition path toward full NexusOS adoption for users, encourages immediate experimentation and use of its package management features on current systems, and offers clear value propositions for both end-users and system administrators from the outset. + +### **🛠️ Proposed Early R&D for Additional Features** + +These prototyping efforts can run in parallel or be integrated into early phases of the main roadmap: + +* **Prototype User-Level Package Management:** Investigate and implement initial Nim-based mechanisms for isolated user environments without requiring root privileges, leveraging the GoboLinux-style paths. +* **Snapshot & Reproducibility Prototyping:** Develop a NimPak-based toolset (or extend the core DSL) to capture, reproduce, and manage reproducible environment snapshots. +* **Portability Layer for NimPak (Feasibility Study):** Research and prototype NimPak’s initial compatibility tooling and APIs to ensure its core package management logic can operate effectively atop popular distributions (e.g., Ubuntu, Fedora, Arch) for managing user-level or project-specific environments. + +### **🎖️ Conclusion for Additional Features** + +These additional features significantly enrich NexusOS’s initial vision, enhancing usability, autonomy, reproducibility, and compatibility. This ensures NexusOS not only serves as a next-generation OS and package manager but also positions its core "NimPak" technology to deliver concrete value in existing Linux ecosystems, accelerating adoption and practical usage.

If remote is slow or unavailable, it falls back to local cache or building from source. + +**Q: How much bandwidth does remote cache use?** +A: Only when downloading artifacts. A typical package is 10-100MB. With good cache hit rates, bandwidth usage is minimal. + +**Q: Can I use remote cache without local cache?** +A: No, local cache is always used. Remote cache supplements local cache for team sharing. + +**Q: What happens if remote cache is down?** +A: Builds continue normally using local cache or building from source. Remote cache is optional and non-blocking. + +**Q: How do I clear remote cache?** +A: Contact your cache server administrator. Remote cache clearing is typically done server-side with retention policies. + +**Q: Can I host my own cache server?** +A: Yes!

Verifiable artifacts. Runtime predictability. Government architecture. Layered policy via .npk. Immutable roots. Declarative runtime control. Philosophical payload.

Nim-Powered Core & Hybrid DSL + +* A robust, statically-typed foundation built in Nim, ensuring performance and reliability. +* **Hybrid Recipe Approach:** + * An elegant, high-level Nim-based Domain Specific Language (DSL) leveraging metaprogramming for concise, powerful, and type-safe package definitions and system configurations ("Mastery Mode"). + * A simplified, declarative recipe format (e.g., YAML-like or a restricted Nim syntax, inspired by AerynOS "stones") for common use cases and as a target for imported recipes. This "Easy Mode" format translates internally to the full Nim DSL, ensuring clarity and human-readability for basic package maintenance. +* **Direct NimScripting Capability:** Alongside the DSL, NexusOS provides the ability to use NimScript directly for highly sophisticated or bespoke package and system building tasks. This offers maximum flexibility and an immediate power ramp, especially during early development phases. + +### 2. Universal Recipe Ingestion & Translation + +* Strategic ingestion and translation of package definitions from established ecosystems, primarily **Nixpkgs** (treating .nix as a declarative "Kalkül") and **Arch PKGBUILDs**. +* Ensures immediate, vast software availability, bootstrapping a rich ecosystem from day one. + +### 3. GoboLinux-Inspired Filesystem Model + +* Intuitive, versioned application directories (e.g., /Programs/AppName/Version), enhancing clarity and simplifying manual inspection. +* Effortless activation and rollback of application versions via managed Current symlinks. + +### 4. Atomic Transactions, System Generations & Bootloader Integration + +* Default transactional integrity for all system modifications, creating immutable "generations" (inspired by NixOS/Guix/AerynOS). +* Guarantees system consistency: operations complete fully or not at all. +* **Bootloader Integration:** Native support for Limine to list and boot into previous system generations, enabling seamless A/B style rollbacks at boot time for maximum system recovery capability. +* Pragmatic overrides (e.g., --allow-partial-update) for expert-driven, targeted operations. + +### 5. Sophisticated Version, Channel & Retention Management + +* Native support for distinct software channels (stable, LTS, testing, git-dev). +* User-configurable, fine-grained retention policies (defined in the Nim DSL) for managing package versions and disk space intelligently. + +### 6. Programmable, Guix-Inspired Build System with Type-Safe "Macros" + +* Moving beyond shell-script dominance, build logic is expressed directly in typed Nim. +* Define reusable "build systems" (for Autotools, CMake, Meson, Cargo etc.) as Nim modules. +* **Type-Safe Build Templates (Nim Metaprogramming):** Instead of simple text-based macros (like AerynOS's %make), NexusOS will utilize Nim's templates and macros to create structured, type-safe, and highly maintainable build abstractions. This captures the simplicity and standardization benefits while adding compile-time checking and greater extensibility. + * Example (Conceptual Nim DSL): + buildPackage("zlib", "1.3.1"): + source("https://zlib.net/zlib-1.3.1.tar.gz", sha256 = "...") + useCMake(opts = ["-DBUILD_TESTING=OFF"]) // Type-safe template + +* Offers deep customization and control akin to Guix, but with Nim's paradigms. + +## 🛠️ Core Engine Architecture: Leveraging Nim's Advanced Capabilities + +The choice of Nim as the foundational language for NexusOS is a deliberate, strategic decision rooted in its unique and powerful capabilities. The nexus and nip tools are not simple scripts; they are sophisticated, high-performance pieces of system infrastructure. Their architecture is designed to leverage Nim's most advanced features to deliver deterministic performance and massive concurrency. + +### 1. Memory Management: Determinism via ARC/ORC + +This choice is about performance predictability and suitability for systems programming. + +* Garbage Collection (GC): The default, traditional GC prioritizes developer convenience. While robust, it can introduce non-deterministic "stop-the-world" pauses to clean up memory. For a simple command-line tool that runs and exits, this is often acceptable. For a long-running daemon or a core system utility where responsiveness is key, these pauses are a liability. +* ARC/ORC (Automatic Reference Counting / Ownership): This is our choice for NexusOS. It is about deterministic performance. Memory is freed the instant it is no longer referenced, similar to the RAII model in C++ or Rust's ownership system, but without the manual memory management or the complexity of a borrow checker. This eliminates unpredictable pauses, resulting in smoother, more consistent performance. The trade-off—a tiny, constant overhead for updating reference counts and the need to manually break rare reference cycles—is a worthwhile price for the robustness and predictability required of core system infrastructure. + +Verdict for NexusOS: We will build with ARC/ORC from the start (--gc:orc). A package manager and system orchestrator must be as predictable and real-time as possible. The deterministic nature of ARC/ORC is a perfect match for the low-level, high-performance tasks we will implement, such as file hashing, process management, and data deduplication. + +### 2. Concurrency: A Hybrid Model for Maximum Throughput + +This is not an "either/or" question. The correct architecture uses both of Nim's concurrency models strategically for different tasks. + +* async is for I/O-bound work. + * Use Case: Fetching dozens of source tarballs from the network, downloading pre-built .npk binaries, checking hashes of large files on disk. + * Why: These tasks spend most of their time *waiting* for the network or disk. async allows a single OS thread to efficiently juggle hundreds of these waiting operations without the heavy overhead of creating a dedicated thread for each one. It's about maximizing throughput when the CPU is not the bottleneck. +* spawn is for CPU-bound work. + * Use Case: Compiling source code (e.g., running GCC on a large C++ project), compressing final .npk packages. + * Why: These tasks will max out a CPU core. Running them in an async context would block the entire event loop, freezing all other I/O operations. spawn creates a true OS-level thread that the kernel can schedule on a separate CPU core. This allows for true parallelism, enabling us to build multiple packages simultaneously and fully utilize a multi-core processor (the equivalent of make -j8). + +### 3. The Hybrid Architecture in Practice + +The nexus build orchestrator will be architected as follows: + +1. The Orchestrator (Main Thread using async): The main nexus process runs an async event loop. Its job is to manage the overall workflow. It will parse the dependency graph and use a pool of async workers to fetch all sources and check all hashes concurrently. This phase is all about I/O saturation. +2. The Build Farm (Thread Pool using spawn): Once the sources for a package are ready, the async orchestrator will *not* build it directly. Instead, it will submit a "build job" to a thread pool. This pool will consist of a fixed number of worker threads (e.g., matching the number of CPU cores). Each worker thread will pull a job from the queue, spawn the compilation process, and wait for it to finish. This phase is all about CPU saturation. +3. Deployment (Back to async): Once a build is complete, the worker thread notifies the main orchestrator. The orchestrator can then handle the final deployment—atomically moving the build output to the final GoboLinux-style path—using async file I/O. + +This hybrid model gives us the best of all worlds: maximum I/O throughput for fetching and maximum CPU parallelism for building, all orchestrated cleanly by a single, responsive main process. Nim is exceptionally well-suited for building exactly this kind of sophisticated, multi-paradigm system. + +## 🛠️ Core Engine Architecture: The Nim & Janet Duality + +NexusOS is built on a principle of architectural integrity: using the right tool for the right job. While the core engine, build orchestrator, and the primary NimPak EDSL are forged in statically-typed Nim for maximum performance and compile-time correctness, we explicitly recognize that not all system logic is static or predictable. For this, we embed Janet—a modern, lightweight, and powerful Lisp—as a first-class citizen within our toolchain from the very beginning. + +Janet serves as the dynamic superglue of the system, the designated successor to fragile and opaque Bash scripts for handling runtime logic. Its role is to manage tasks where the inputs are "fuzzy," unclear, or only available at execution time. This includes fetching dynamic configuration values from a web service, interfacing with non-standard APIs, or executing conditional deployment logic based on live system state that cannot be known at compile time. Unlike shelling out to Bash, the embedded Janet interpreter operates within a controlled context, allowing for structured data exchange (not just text streams) with the core Nim engine and offering a safer, more robust, and debuggable environment for dynamic tasks. + +Nim provides the immutable, verifiable skeleton of the system, while Janet provides the adaptive, intelligent nervous system that allows it to react dynamically. This hybrid approach is not a compromise; it is a deliberate design for creating a system that is both resilient and responsive from day one. + +## 📦 Additional NexusOS Capabilities & Strategic Features + +The following concepts, inspired by the best aspects of Guix and the potential for Nim-centric packaging (conceptualized as "NimPak"), will significantly enhance NexusOS’s practicality, usability, and user autonomy, offering paths for broader adoption. + +### 1. Per-User Package Management (Guix-inspired) + +By default, NexusOS empowers every user on the same machine to independently manage their own software environment without the need for superuser privileges: + +* **User-Level Autonomy:** Users can safely install, upgrade, and manage packages in their own namespace, entirely isolated from the global system and other users. +* **No Root Required for User Packages:** Eliminates security risks and administrative friction associated with global privilege escalations for routine user-specific package operations. +* **Ideal for Multi-User Environments:** Facilitates shared server scenarios, research clusters, and academic environments where user software autonomy and system stability are paramount. + +### 2. Robust Reproducible Environments (Guix-inspired) + +NexusOS guarantees reliable reproducibility of computing environments, critical for software developers, researchers, and system administrators alike: + +* **Environment Snapshots:** Easily build and capture complete software environments that include applications, libraries, runtime configurations, and their precise dependencies. +* **Reproduce in Time:** Restore an exact snapshot of your software environment at any future point, ensuring the same outcomes years from now, regardless of intervening system changes. +* **Containers & Virtualization:** Seamlessly create and deploy containerized environments (e.g., OCI images) or VM images based on reproducible NexusOS definitions, significantly enhancing CI/CD pipelines and reproducible research. +* **Example Usage:** + * Build an environment today. + * Reproduce precisely the same environment years from now. + * Guarantee consistent results regardless of system updates or underlying hardware changes. + +### 3. NimPak — Unified Nim-Centric Package Management (Portable Core) + +"NimPak" embodies NexusOS’s powerful Nim-native package management vision, designed as a robust, unified API ecosystem within the Nim language, with potential for portability: + +* **Single Language, Infinite Possibilities:** Leverage NimPak’s APIs, including high-level embedded domain-specific languages (EDSLs), to define and manage packages, dependencies, and even whole-system configurations with exceptional clarity and type safety. +* **Potential Integration with Existing Distros:** The core NimPak tooling could be designed to integrate atop any UNIX/Linux distribution without interference or conflicts with the host distribution’s native package manager (APT, DNF, Pacman, etc.). +* **Cross-Distribution Utility:** This portability simplifies adoption by allowing users and developers to experience NimPak's benefits (e.g., for managing development projects or specific application stacks) on existing systems, rather than requiring an immediate wholesale migration to NexusOS. +* **Example Conceptual Usage (NimPak API):** + # Conceptual NimPak definition + definePackage("myapp", "1.0.0"): + source(git = "https://github.com/example/myapp.git", tag = "v1.0.0") + dependencies: + useCMake(["-DBUILD_EXAMPLES=ON"]) # A type-safe build system template + # This definition could potentially be built and managed by NimPak tools + # on Ubuntu, Fedora, Arch, or NexusOS. + +### 🚩 Integration & Advantages of These Additional Features for NexusOS + +By incorporating these powerful ideas, NexusOS uniquely combines: + +* User-level autonomy and isolated environments (Guix-inspired). +* Deep reproducibility and environmental consistency (Guix-inspired). +* Elegant Nim-native interfaces and a unified tooling vision (NimPak concept). +* A potential path for seamless compatibility and integration of its core package management technology across existing Linux/UNIX distributions. + +This holistic approach enables a gentle, incremental transition path toward full NexusOS adoption for users, encourages immediate experimentation and use of its package management features on current systems, and offers clear value propositions for both end-users and system administrators from the outset. + +## 🎛️ Layered User Experience + +NexusOS caters to diverse expertise through a tiered interface: + +| User Level | Target Audience | Primary Interaction & Capability Focus | +| :---- | :---- | :---- | +| **Easy Mode** | End-Users, Basic Maintainers | Simple CLI (ni install nginx, nu upgrade-system).
