inspiration

• tilir
• introduction to C (ru)
• practice C bash/linux/gcc (ru)

vision

• managed (C programming language model)
• safe
• friendly
• extensibe
• simple
• tested (100% code coverage)

brief

• VM managed types / C API

• user defined types / extensibility system

  1. C API
  2. memory management
  3. garbage collection

• development environment:

  1. WSL2/devcontainers
  2. Ubuntu 22.04.3 LTS

• C API generated docs (doxygen):

  1. docs

media links

• streaming channels

updates

• 2023

  1. added v1 core Virtual Machine (vm1) with types:

  2. added support including:

     1. file IO
     2. string manupulation methods
     3. search

features

• List<T> implementations
• code coverage
• coverage hot-reload

• automatic garbage collection implementation (GC)
• GTK GUI app demo ready to run on containerized environment

readme

repo is ready to run on containers, WSL, remote hosts.

remote development

• installation from git repo (manually)

Installs sources from git repo

eval `ssh-agent -s`
git config --global user.name "$USER_NAME"
git config --global user.email "$USER_EMAIL"
git clone https://github.com/default-writer/c.git

clang

docs

containers

manual installation (minimal install)

• init

Sets up primary/optional tools and git hooks

./bin/init.sh --setup
./bin/init.sh --optional
./bin/init.sh --hooks

• rexo

./bin/utils/install.sh --submodule-rexo

GTK GUI app development

setup

• add/update Visual Studio Code environment settings:

"environment": [
  {
    "name": "UI_MODE",
    "value": "--ui"
  }
]

• run command line build

cd gtk
./bin/build.sh --target gtk-experiment1 --clean
UI_MODE=--ui ./build/gtk-experiment1

shell scripting documentation

all shell scripts

• are self-documented
• placed in ./bin folders
• detects execution as user or root (sudo)
• runs with required and optional command-line parameters

history

local repos

Use CLI or git.
