# ccshell A complex (or simple?) shell implemented in C++ (some C codes (job control) will be replaced by C++ soon, but anyway C is still subset of C++) NO vibe coding / AI / Codex / Claude Code / Antigravity / Cursor / Kiro Only the very traditional methods (stack overflow, man, cpp reference, etc.) are used 👉 I am just learning these stuff as doing this project, so if you find something stupid, please just open issue/PR 😭 ~~Very simple and boring things (just job CRUD, really) are copied from CS:APP (I did that lab, so they're here), but will be refactored soon~~ 👉 Job system will be rewritten, because CSAPP job model is not how sh/bash/zsh works, and then it will be in C++ ## Feature Support very complex syntax with a systematic language analysis system (it is implemented with recursion, thus it would not have any problems with long command) - async command (aka background) - logic operators based on exit value - brackets - multiple commands - TODO: pipeline, expansion, etc. - Limit: terminal reflow is being done, but it may take some time A fantastic line editor has been DONE, and the only things left are pipeline and async! 😘 ## Build 👉 ISO C++26 is used, please make sure gcc-14 or above is installed, and gcc-15/16 is most recommended (clang doesn't work well, don't use it!) ```sh make magic-enum # download dependencies make # build project ``` ## Usage Valid options can be found here `include/option.h` Or just run without any options ```sh build/ccshell ``` ## Development ignore the test file (deprecated) ```sh git update-index --skip-worktree src/test.cc ``` ## Legal info Copyright (C) _ov4 This is free software; see the source for copying conditions.
