[Haskell-cafe] Announcement: Gipeda, the git performance dashboard

a while ago, I set up a performance dashboard¹ for GHC, based on
codespeed², but I was dissatisfied, so in the end, I wrote a new one,
for “Git Performance Dashboard”. The git in the name as, in contrast to
codespeed, I do not try to be VCS-agnostic but do want to use and expose
the structure of your project’s git repository in the output.
You can have a look at http://perf.haskell.org/ghc. It should be
relatively self-explanatory. Just note that by default it hides boring
stuff (commits and results with no significant change), you can select
what to show in the top-right corner.
The idea behind gipeda is relatively simple. Starting with a directory
with one file for each of your project’s benchmarked commit, gipeda
digests this to produce a bunch of JSON files. It uses shake³ to avoid
(using handlebars as a templating engine, and other JS libraries like
jQuery and flot) then presents this data, in a hopefully snappy and
I have announced the GHC instance on the ghc-dev mailing list⁴, so why
do I write here as well? Because you can use gipeda for your own
projects! And because you can contribute!
The program is not GHC-specific, so if you have a way to produce
benchmark numbers (or any other kind of metric) for your project, you
can feed them to gipeda to be visualized. See the README at
https://github.com/nomeata/gipeda for instructions (and ask me if you
are stuck). If it makes sense we can host the result at
http://perf.haskell.org/ (but you still need to run the benchmarks
And although it is quite nice so far, there are a lot of things it
should also be able to do. Here are a few ideas:
* Integrate data from multiple build hosts.
* Compare the results from arbitrary two commits.
* Visualize non-linear git histories, e.g. due to branches.
* Know about named branches and tags.
* RSS feeds and email notifications.
* Find a way to efficiently run gipeda on travis.
* General UI polishing.
touching any Haskell, so if you want to contribute, I’m sure you’ll find
I plan to work on that during ZuriHac⁵ (only two more weeks), so if you
are there and looking for a project, please join me!
