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.
fsevent_watchhas a damn simple parseable output (tab-delimited)

fsevent_watchdoes 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

- 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'
- just run
make install(and make sure you have a compiler)
- fsevents API does not follow symlinks
