[PATCH v1 5/5] Add a sample query-fsmonitor hook script that integrates with the cross platform Watchman file watching service.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



To use the script:

Download and install Watchman from https://facebook.github.io/watchman/
and instruct Watchman to watch your working directory for changes
('watchman watch-project /usr/src/git').

Rename the sample integration hook from query-fsmonitor.sample to
query-fsmonitor.

Configure git to use the extension ('git config core.fsmonitor true')
and optionally turn on the untracked cache for optimal performance
('git config core.untrackedcache true').
