Usage

$ guardian --init

It will create a guardian.yml file to use by Guardian.

guardian.yml

guardian.yml is a simple YAML file.

Simply it has YAML documents with seperated by --- line and each document has files and run keys.

files key needs a glob pattern, and run is a shell command what to run.

files: ./**/*.cr
run: crystal build ./src/guardian.cr
---
files: ./shard.yml
run: shards install

%file% Variable

Guardian replaces %file% variable in commands with the changed file.

files: ./**/*.txt
run: echo "%file% is changed"

Think you have a hello.txt in your directory, and Guardian will run echo "hello.txt is changed" command when it's changed.
