A watchman for your directories. Rorshach allows you to watch your directories for changes and trigger certain commands when these events occur.
At the moment the only way to install is from crates.io (https://crates.io/crates/rorshach).
Run cargo install rorshach to install it on a linux machine.
./rorshach -f <dir> [-config <config_path>] [-t <seconds_to_wait_before_reload>]
The default config file lies at ~/.rorshach.conf
The config file has rules of the following form
EVENT PATTERN ACTION
... ... ...
EVENTS can be CREATE, DELETE RENAME or MODIFY. Each event is trigger when a file in the directory being watched is CREATED, DELETED, MODIFIED or RENAMED respectively.
PATTERNS are patterns to match the files in a directory. Example *.cpp matches all the C++ files in a directory.
ACTIONS are commands that can be executed when a EVENT occures
There are following environment variable available while executing an action, they are :-
{FULLPATH} - Full path to the file,
{BASEDIR} - Path to the directory that rorshach is watching
{NEWFULLPATH} - New Path to the file, when a file is renamed else empty.
CREATE * echo " New file named ${FULLPATH} created"
The above will print a line of the form New file named <file-name> created every time a new file is created.
MODIFY *.cpp g++ ${FULLPATH} {BASEDIR}/test
Whenver a change is detected in a c++ file, rorshach will compile that file and create an executable named test in the base directory
- Add more events to listen like
Rename - Support execution of a chain of commands for a single event
- Move Command Line passing to a different struct
-
Add a threadpool to execute each task once an event is spawned - Add a pub-sub mechanism for events
- Add Tests?
- Move parse_rules to an enclosing struct
- Use
logcreate for logging. - Provide better messages for errors.
- Add a pub sub mechanism to listening to events and consuming them
