rlgl

Play red light, green light with files.

rlgl allows you to run a command when files change.

Installation

You will need to have git and cargo installed to install rlgl.

$ git clone https://github.com/wafelack/rlgl.git
$ cd rlgl/
$ make
$ make install [PREFIX=/wherever/you/want]

Usage

rlgl reads a files list on the standard input and takes a command to run as argument.

Read rlgl --help for more information about possible flags.

Examples

Recompile your project each time a file is edited:

$ find -name *.rs | rlgl -qs cargo build

Link your dotfiles when they are edited (with rdfm):

$ sed '/^#/d' ~/.config/.dotfiles/dotfiles.rdfm \ # Remove comments from dotfiles.rdfm
  | sed -r '/^\s*$/d' \ # Remove blank lines
  | awk -F'=' '{ print $1 }' \ # Split on '=' and take the first part.
  | rlgl -qs rdfm link
