Finding code changes the easy way

I just did an update to my Redmine hours. It hadn’t been done in way too long and thus took me way to long to do it. I needed some way to automatically browse all of the code commits that I have done in a particular time, in all of the different repos that our development is spread across. Turns out that all of the pieces to do this are already in place… one just need to read a few man pages to put them all together.

First of all, let’s find all of my hg repositories:

james@basalt ~ $ find ./ -name .hg
./code/hg/pydap-3.1/.hg
./code/hg/pydap.git/.hg
./code/hg/analytics/.hg
./code/hg/pydap.responses.netcdf/.hg
./code/hg/gpstools/.hg
./code/hg/rat2/.hg
./code/hg/pydap.handlers.hdf5/.hg
./code/hg/PyCDS/.hg
./code/hg/ziperator/.hg
./code/hg/pupynere_bitbucket/.hg
./code/hg/crmprtd/.hg
./code/hg/data_portal_dev/.hg
./code/hg/pgraster/.hg
./code/hg/pydap.responses.html/.hg
./code/hg/py_modelmeta/.hg
./code/hg/pydap.handlers.pcic/.hg
./code/hg/pydap.handlers.sql/.hg
./code/hg/pydap_leftovers-3.2/.hg
./code/hg/pydap.responses.xls/.hg
./code/hg/pydap-3.2/.hg
./code/hg/crmp/.hg
./code/hg/pdp_util/.hg
./code/hg/pupynere/.hg
./code/hg/naggerbot/.hg
./code/hg/pydap.handlers.csv/.hg
./code/hg/data_portal_pycharm/.hg
./code/hg/openid2rp/.hg
./code/hg/pdp/.hg
./code/hg/pydap-3.2-rob/.hg
./code/hg/data_portal-2.0/bootstrap/src/modelmeta/.hg
./code/hg/data_portal-2.0/pydap-3.2/.hg
./code/hg/data_portal-2.0/pydap/.hg
./code/hg/data_portal-2.0/.hg
./code/hg/pydap.responses.aaigrid/.hg

That was easy. So I want to run “hg log” in each of those directories. I could try to use cut or something to pull the “.hg” off of each directory, but hey, it turns out that find has a -execdir option which allows you to run a command in the directory where each file is found. Perfect.

Now to craft the hg log command. I want all of my commits within a certain date range and those options already exist. So, putting it all together:

james@basalt ~/code/hg $ find ./ -name ".hg" -execdir hg log -v -d "2014-01-20 to 2014-01-27" -u "James Hiebert <hiebert@uvic.ca>" \; | head -50
