cw

A generic command wrapper

TODOs

• use CreateProcessW
• nested .cw script
• .secret file (as a replacement for hardcoded .bat / .sh)
• basic string functions
  • slash conversion
  • string part extraction
• built-in
  • IO
    • replace content (template file)
  • http curl client
  • multiple instance mutex
    • https://github.com/dirkarnez/cpp-mutex-playground
• child process stdin + stdout Redirection
• ohmyzsh/ohmyzsh
• malxau/yori: Yori is a CMD replacement shell that supports backquotes, job control, and improves tab completion, file matching, aliases, command history, and more.
• walterschell/Lua: CMake based build of Lua (5.4.3 and 5.3.3)
• GUI for command list with tags
• Repl mode
• Variables
  • dirkarnez/string-substitutions-playground
  • adeharo9/cpp-dotenv: Loads environment variables from .env files for C++ projects.
  • dirkarnez/boost-env-boilerplate
  • passing variable or return value between steps
  • session-like variable (like docker container id) for random access
  • conditional step (like github workflow)
    • prerequisites
• Profiles (e.g. for C++ development)
  • environment settings with execution placeholder(s)?
• Autocompletion
  • say typing "docker" will show all things related to docker
  • .cw scripts and their usage are not meant to be memorized
  • fuzzy search on .cw script contents and tags
• Should support cli (for CICD environment)
• timeout

  • #include <iostream>
    #include <boost/process.hpp>
    #include <boost/asio.hpp>
    
    namespace bp = boost::process;
    
    int main() {
        boost::asio::io_context io_context;
        bp::child c("sleep 5", bp::std_out > stdout, bp::std_err > stderr, io_context);
    
        // Set a 5-second timeout
        io_context.run_for(std::chrono::seconds(5));
    
        // Check if the child process has finished
        if (c.running()) {
            // If the child process is still running after 5 seconds, terminate it
            c.terminate();
        }
    
        return 0;
    }

Grammar

import default_env;

export const name: string = "";
export const (): error => {
  var hour: int = prompt("", 0);
  var minute: int = prompt("", 0);
  var second: int = prompt("", 0);

  synchronized download_movie(), download_music()

  return exec({
      ...default_env,
      "PATH": Path(C:/Windows/System32)
    },
    this_script_location, //working_directory
    "shutdown -s -f -t ${(hour * 60 * 60) + (minute * 60) + second}",
    5
  );
}

Notes

• Should not touch %PATH%, including this software
  • pin to taskbar is ok
