i’m trying to slim things down — it’s easy to fill a 256gb hard drive on a mac when you like poking around other people’s source code on github. and, perhaps, 100 of your own repos.

i wrote two commands for git in bash to supplement git.

git size

as run on my mac (after i zapped 50gb of git repos):

the ‘git size’ sub-command: https://github.com/paul-hammant/git-size (~patches~ prs welome).

running it

$ git size jbehave/jbehave-core/
jbehave/jbehave-core: git size:
  .git folder:  31m
  checkout: 11.6m
  ignored: 8.1m
  total:  50m 

or, recursive and csv:

$ git size --csv --csv-headers --recursive .
directory_name,dot_git_folder_size,checkout_size,ignored_size,total_size
"jbehave/jbehave-core",31320,11924,8344,51588
"jbehave/jbehave-tutorial",728,220,0,948
"jbehave/jbehave-web",1772,1396,920,4088
"maven-hpi-plugin",1784,620,1328,3732
"xunit-plugin",1416,3588,14928,19932

installation

visualizations

the site for visualizations: https://paul-hammant.github.io/git-size/ . it is the gh-pages branch of the git-size repo, of course.

that pic is the example linked to from the homepage, above. the link itself (so you can see):

yes, that’s a long url. it’s ok the browser can handle it. note that the stuff to the right of the # will not be sent to the github web-server hosting the files. the stuff to the right of the # is a base64 encoded form of the csv above, or course.

git slim

this might be buggy, but it works for me - a way to reduce the depth of a clone in-situ.

the ‘git slim’ sub-command: https://github.com/paul-hammant/git-slim

$ cd jbehave/jbehave-core
$ git slim
size of .git folder before:  31m, best case size after: 3.4m (approx).

installation

thoughts after making these

bash is quite picky generally, but there’s a particular snafu that bogged me down quite a bit:

unix command xargs can blow up when using it to calculate the size of a list of files. i had to drop it, and iterate over files adding up kb sizes. there’s a -a option but it’s not available installed on base os x.

i could have installed gnu’s xargs like so brew install findutils , but it would be gxargs instead of xargs and though still possible, it would be harder to keep git-size linux compatible.

the d3-using sunburst chart really has to stay online - it is too much for a simple bash-script to handle. it is also a fork of something pre-existing , and i had trouble making it into a single page that could switch between the four size types passed in via csv (the four radio buttons at the top).

lastly, i really wanted to do a treemap , but nothing in javascript/svg was quite as pretty as the treemap of the fabled disk inventory x . so sunburst it was.
