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 $src)/include |
config_folder |
Path to rooki config folder |
What rooki
does when you do rooki yourscript
is the following
- Create a temporal file and save the path in the variable
f
. - Create a
bin
path out of themd5
hash of the source script, the bin will be stored in$XDG_CONFIG_HOME/rooki/
. In the case that yourXDG_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
