Subject: [PATCH v2 6/6] fsmonitor: add a sample query-fsmonitor hook script for Watchman
Date: Thu, 18 May 2017 16:13:33 -0400 [thread overview]
Message-ID: <20170518201333.13088-7-benpeart@microsoft.com> (raw)
In-Reply-To: <20170518201333.13088-1-benpeart@microsoft.com>
This hook script integrates the new fsmonitor capabilities of git with
the cross platform Watchman file watching service. 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').
