Jans is a tiny language-agnostic tool to automate compilation. Feed it with a json structure to describe your project and it will compile it automatically when it sees a change. Change detection of a file is based on the last modification date, so saving with no changes also counts.

First, type the command jans --init that will create a json file named jans.config.json with a content like this:

{
	"rules": [
		{
			"name": "the rule name",
			"path": "the path to check",
			"excludes": ["file to exclude 1", "directory to exclude 1"],
			"extensions": [
				"your file extension 1",
				"your file extension 2"
			],
			"command": [
				"your command",
				"your command parameter 1",
				"your command parameter 2"
			]
		}
	],
	"delay": 1
}

Then change it depending of your project requirements. you can have as much rules as you want. The delay parameter sets the sleep time between each check, in seconds.

Then jans --run your-config.json.

Alternatively, you can run jans through haxelib like this.

haxelib install jans
haxelib run jans --init #to init your config
haxelib run jans --run your-config.json #to run your compilation

With no config file provided, jans will try to open jans.config.json in the current directory.

Jans is complied with the use of jans itself, so if you have haxe, you can try it on this repo alone.
