grackle

Grackle is a recursive directory synchronization tool that watches a file and triggers when it changes.

usage

git clone https://github.com/peterwhitesell/grackle.git
cd grackle
npm install
chmod +x grackle
./grackle path/to/config.json

config.json should look like this with as many entries as you'd like:

{
    "test1": {
        "exclude": "/home/peter/webdev/grackle/tests/exclude_git",
        "watch"  : "/home/peter/webdev/grackle/tests/watch",
        "source" : "/home/peter/webdev/grackle/tests/test_dir/",
        "target" : "/home/peter/webdev/grackle/tests/test_dest/"
    },
    "test2": {
        "watch" : "/home/peter/webdev/grackle/index.js",
        "source": "/home/peter/webdev/grackle/tests/test_dir/test_inner_dir/",
        "target": "/home/peter/webdev/grackle/tests/test_dest/"
    }
}

For each entry, exclude is an optional file that lists patterns to exclude in the synchronization. watch is the file Grackle watches. When that file changes, Grackle uses rsync to copy source into target.

For instance, if you have path/to/a and path/to/b/ and you want to have path/to/b/a/, config.json should include:

{
    ...: {
        ...
        "source": "path/to/a/",
        "target": "path/to/b/"
    },
    ...
}

Grackle overwrites any conflicting files in the target. It also deletes any files previously in target that are not in source and any files matchced in exclude.
