Overlook

A commandline app that will watch your folder and monitor any changes. When a change occurs, Overlook will execute (or restart) a command you specify. Overlook is platform independent and will work with anything from writing a README file, to developing a service.

Build It Yourself

Usage

There are 2 ways to use Overlook. You can either use it completely on the command line, or setup a .overlook config file.

.overlook

The .overlook file is a configuration file that defines environment variables, what to ignore, what to watch and what to excute on change. To create a .overlook file in your current directory, simply run:

$ overlook init

This will generate the following file:

{
  "ignore" : [
    ".git",
    ".gitignore",
    ".overlook"
  ],
  "env" : {
    "example" : "variable"
  },
  "execute" : "ls -la",
  "directories" : [
    "build",
    "tests"
  ]
}

Available

• ignore : A list of files or folders that Overlook should ignore changes on.

• env : Environment variables overlook can set for you when running/restarting.

• execute : A list of commands for overlook to run when a change has been observed.

• directories : Directories that should be watched for changes.

Commandline

Overlook can run without a .overlook file. You can run overlook help for a list of available commands

The main command you will use with overlook will be watch. This command is what tells overlook what to watch for changes and what to execute.

The required flags for overlook watch are:

• e, execute What is executed when targets are changed.

• h, help Show help information for this command.

• i, ignore Comma separated list of files or directories to ignore.

• t, target Comma separated list of directory or files to monitor.

Example:

$ overlook watch -t /folder/to/watch -e /script/to/execute

To Do

• Parallel observations/executions
• Task running
