Continuous build on the cheap, using inotify, cmake and a terminal

inotify-cmake.sh

#!/bin/bash
# Watch paths (given as arguments), automatically build when something changes.
# The script does a couple opinionated things to make my life easier:
#
#  * Terminal scrollbuffer is reset before each iteration, simplifying scrolling.
#  * I use a filter script to colorize gcc output (clang errors would be nicer).
#  * Output is copied to a log file (/tmp/build.log).
#    - I open this file in Sublime or vim, which reloads the file on change (each build).
#
# Usage:
#
# devbox:myproject$ mkdir -p build && cd build
# devbox:build$ cmake ..
# devbox:build$ inotify-cmake ../src ../test ../CMakeLists.txt
# ... Profit!
#
# Note: highlight-gcc.py comes from https://gist.github.com/2189147
