File watcher

Lightweight file watcher. Listens for file changes specified in config file and then executing commands also specified in config file. It is intended to run as root if users are specified for executing commands.

Example of toml file:

# .watch.toml
# list here all events and commands that it should execute

[[rules]]
name = 'run live preview on file change'
dir = '/path/to/dir'
watch_patterns = ['**/filename']
recursive = true # not required
[rules.command]
command = '/path/to/command'
user = 'user' # not required
group = 'group' # not required
working_dir = '/path/to/cwd/' # not required
env = [
	['MY_ENV', 'value']
] # in form of ['key', 'value'], not required

# another rule which will exectue commands as user who executed this program
[[rules]]
name = 'some other rule'
dir = '/path/to/dir'
watch_patterns = ['**/filename']
[rules.command]
command = '/path/to/command'

This will create two rules, one will execute commands as specidied user, group and working dir, other will execute commands as user and group who executed watcher and in current working dir.
