C

The c repository implements the curriculum in C.

Summary

Property Value
Repository dialectic-playground/c
Status Active: Project 00 implemented
File extension .c
Release line C17 (GCC 16 in the container)
Build / package tool make
Curriculum Submodule pinned to v1.5.0
Brand accent #A3A3A3, glyph c; GitHub Linguist #555555 (lightened for contrast on the dark background)

Language characteristics

Aspect C
CLI classification Included
Image category Native Toolchain
Access to OS primitives Absolute & Direct (POSIX system calls)
Entry-point mechanism Kernel drops argc and argv pointers directly into main()

Toolchain

Environment Toolchain
Container gcc:16-trixie, pinned by digest in Containerfile, plus make, python3, and clang-format (19.1.7, Debian trixie)
Native CI GCC on Linux, Apple Clang on macOS, MinGW-w64 GCC on Windows; clang-format==19.1.7 from PyPI on all three

make toolchain verifies both environments. For C, the native compiler differs by OS, so it runs a language-standard compile-and-run probe. It also checks that clang-format is version 19.1.7 everywhere.

Project tooling

What each project's Makefile hooks run. Versions are the ones pinned in the repository (lockfile, Containerfile, or CI).

Purpose Tool
Unit tests Plain C checks with the repository's own small runner (src/tests/unit_test.[ch])
Lint Warning-free build (-std=c17 -Wall -Wextra -Wpedantic -Wshadow -Wstrict-prototypes -Wconversion -Werror) and clang-format --dry-run --Werror
Format clang-format -i, clang-format 19.1.7 (Google style, 100 columns; one .clang-format shared with C++ and Objective-C)
Dependencies None (no package manager)
Build output (BIN_DIR) build/bin/: the native executable (dp-hello.exe on Windows)
Install Copies the executable to $(BINDIR)

Implemented projects

A project is implemented once it is listed in IMPLEMENTED in the repository's root Makefile. CI then builds, lints, and tests it in the container and natively on Linux, macOS, and Windows.

Notes

  • Windows (MinGW-w64): the tools enter through wmain (-municode), convert the UTF-16 command line to UTF-8, and switch stdout and stderr to binary mode, so arguments and output bytes match Linux and macOS.
