Introduction

DCR (Dexoron Cargo Realization) is a Cargo-style CLI for C/C++ projects.

Current DCR focuses on a simple, predictable workflow:

  • create or initialize a project (dcr new, dcr init)
  • build with debug or release profiles (dcr build)
  • run binaries (dcr run)
  • clean artifacts (dcr clean)
  • update the installed binary (dcr --update)

What is implemented in this version

  • Project configuration in dcr.toml with [package], [build], [dependencies].
  • Recursive source discovery in src/:
    • C: *.c
    • C++: *.cpp, *.cxx, *.cc
  • Compiler selection from dcr.toml (clang, gcc, cl, clang-cl, etc.).
  • ASM support via language = "asm" (GCC/Clang, NASM, GAS).
  • Mixed language builds via language = ["c", "asm"] and similar combinations.
  • Three build kinds:
    • bin (default)
    • staticlib
    • sharedlib
  • Optional custom output directory via build.target.
  • Optional build.platform to pass architecture hints (-march / /arch).
  • Optional build.exclude/build.include for source/header selection.
  • Optional build.roots/build.src_disable to replace the default src/ root.
  • Optional build steps with build.steps and build.post_steps.
  • Optional build.pkg_config integration.
  • Optional build.clean and build.expect.
  • Optional [run].cmd to override run command.
  • Workspace builds via [workspace] with per-project dcr.toml.
  • Path dependencies with include/lib resolution and dcr.lock generation.

Important behavior notes

  • dcr.toml is required for build, run, and clean.
  • run works only with build.kind = "bin".
  • Incremental rebuild tracks source file timestamps and header dependencies (rebuilds when either source or included headers change).
  • Object files are always created under target/<profile>/obj/.
