# DESCRIPTION:
# make-test-file is a script to ease development of the Elixir programming code
# base. Allowing the developer to run selected tests.
#
# INTRODUCTION:
# This script will only be useful if you are hacking into the source code of the
# Elixir programming language itself.
# It eases the process of running a test of a single or multiple test files,
# without the need to have to run all the test in the project.
#
# Normally, if you are editing a file in the elixir project, you will have to
# run the test by doing:
# $ make test_stdlib
# and all the tests in the elixir project will be executed,
# while if you know the test you need to check, you can just do for example:
# $ ./make-test-file lib/elixir/test/elixir/integer_test.exs
# or you can run multiple tests:
# $ ./make-test-file lib/elixir/test/elixir/range_test.exs \
#   lib/elixir/test/elixir/kernel_test.exs \
#   lib/elixir/test/elixir/kernel/*_test.exs
#
# USAGE:
# $ ./make-test-file TEST_FILE [TEST_FILE ...]
#
# INSTALLATION:
# 1. Enter to the root folder of Elixir.
#    $ cd ~/git/elixir
#
# 2. Download this script and make it executable
#    $ curl -o make-test-file -sSfL https://git.io/make-test-file_raw
#    $ chmod +x make-test-file
#
# 3. Add this script to the files that you want to ignore in this project
#    $ git config --local --add core.excludesfile ~/.gitignore_elixir
#    $ echo "/make-test-file" >> ~/.gitignore_elixir
