Nimplate Build System

Overview

The Nimplate build system provides type-safe, isolated, and cacheable source compilation for NexusOS packages. It supports multiple build systems through a unified template interface.

Features

Type-Safe Templates: Compile-time validated build configurations
Environment Isolation: Sandboxed builds prevent system contamination
Build Caching: Hash-based incremental compilation
Multi-System Support: CMake, Autotools, Meson, Cargo, Nim, and custom builds
Artifact Tracking: Complete build result and artifact management

Supported Build Systems

System	Status	Description
CMake	✅ Full	Modern C/C++ builds with configure/build/install
Autotools	✅ Full	Traditional configure/make/install workflow
Meson	🔧 Framework	Modern build system (implementation ready)
Cargo	🔧 Framework	Rust package builds (implementation ready)
Nim	🔧 Framework	Native Nim compilation (implementation ready)
Custom	🔧 Framework	User-defined build scripts

Usage

import nimpak/build_system

# Create build template
let buildTmpl = BuildTemplate(
  system: CMake,
  configureArgs: @["-DCMAKE_BUILD_TYPE=Release"],
  buildArgs: @["--parallel"],
  installArgs: @["--prefix", "/usr"]
)

# Execute build
let result = buildFromTemplate(buildTmpl, "/path/to/source")

if result.success:
  echo "Build completed in ", result.buildTime, "s"
  echo "Artifacts: ", result.artifacts.len
else:
  echo "Build failed: ", result.buildLog

Architecture

NimplateExecutor: Main execution engine
BuildEnvironment: Isolated build environment management
BuildResult: Comprehensive result tracking
Build Caching: Hash-based incremental compilation

Testing

Run the build system tests:

nim c --hints:off nip/tests/test_build_system_simple.nim
./nip/tests/test_build_system_simple

Next Steps

Task 13.2: Integration with CAS and packaging
Enhanced build system implementations
Container-based isolation
Advanced caching strategies
