rooki

A stupid simple script runner supporting c, c++, rust, haskell and virtually anything

Rooki is written in 20 lines of bash, and has a very flexible functionality.

How does it work?

You just write comments as rooki instructions, the only instruction that you have to define is the rooki:spell, which will be run in the shell. Otherwise you can define any flag you want with the name you want for instance in a c file, the following

// rooki:someflag -I$(pwd)
// rooki:someflag -I$HOME

will define a shell variable someflag with the value

someflag="-I$(pwd) -I$HOME"

which later can be used in the rooki:spell section as

// rooki:someflag -I$(pwd)
// rooki:someflag -I$HOME
// rooki:spell cc $someflag $f -o $bin

There are some general variables already defined:

Variable Explanation Example
bin Path to the created binary rooki:spell gcc $f -o $bin
f Path to the temporary source file that will be compiled // rooki:spell gcc $f -o $bin
src Path to the source file, the caller rooki:include -I$(dirname $src)/include
config_folder Path to rooki config folder

What rooki does when you do rooki yourscript is the following

  • Create a temporal file and save the path in the variable f.
  • Create a bin path out of the md5 hash of the source script, the bin will be stored in $XDG_CONFIG_HOME/rooki/. In the case that your XDG_CONFIG_HOME is not defined, it will be stored in ~/.config/rooki/.
  • Remove the shbang (#!/usr/bin/env rooki) on top of your script (if there is any) and copy the script to $f without the shbang.
  • Read the rooki: flags stored in text in your script.
  • Expand shell constructs within these flags, environment variables and general shell commands within.
  • Run the rooki:spell construct, which should be creating a binary in the path $bin.

Quick start

For instance to write a c++ script called hello.cxx just create an executable file hello.cxx and write

#!/usr/bin/env rooki
// rooki:flags -pedantic -std=c++11
// rooki:flags -x c++
// rooki:include -I/usr/include
// rooki:include -I$HOME/.local/include
// rooki:spell g++ $flags $include $f -o $bin

#include <iostream>

int main(int argc, char *argv[])
{
  std::cout << "Hello world" << std::endl;
  return 0;
}

then do

./test.cxx
# or
rooki test.cxx

if you want to see exactly what rooki is doing then set the environment variable ROOKI_DEBUG like this

ROOKI_DEBUG=1 ./test.cxx
