fsevent_watch

The tool allows you to watch filesystem events on a Mac.

This is a standalone fork the C tool inside https://github.com/thibaudgg/rb-fsevent focused on usability and composability with other tools.

Awesomeness

• fsevent_watch has a damn simple parseable output (tab-delimited)

• fsevent_watch does line-buffering so you can even develop the tool with itself!

% ./fsevent_watch -F . | egrep --line-buffered '\.[ch]$' | xargs -t -n1 -I% make
make
clang -c -DCLI_VERSION="\"f785a34\"" -Wno-deprecated-declarations main.c -o main.o
clang -framework CoreFoundation -framework CoreServices cli.o compat.o main.o -o fsevent_watch
make
make: `fsevent_watch' is up to date.
make

^C

• or, for example, authoring a Markdown file with vim and redcarpet

% fsevent_watch -F | grep --line-buffered README.md'$' | xargs -I% -n1 sh -c 'redcarpet --parse-fenced-code-blocks --parse-autolink --render-prettify README.md > README.html'

Building

• just run make install (and make sure you have a compiler)

Caveats

• fsevents API does not follow symlinks
