Hey everyone! It’s my enormous pleasure to present Hex Diff, an official hex.pm service for generating web-based diffs between package versions on Hex. You can find it at https://diff.hex.pm.
Read more about it and why it’s a great tool for the community on the announcement blog post!

Thanks, for the great work done , I have tested on cowboy lib and it highlighted the major difference between version thanks great work !!!

The amount of just cool stuff the Elixir community builds is astounding. Thanks for yet another very productive feature! This will make upgrading our older dependencies a little less scary.

Very useful tool, thanks! Would it be possible to add some information like a total
X files changed, Y lines added, Z lines removedand then+X lines, -Y linesper file?And what about a link on
hex.pm/packageto the latest diff?jola
That’s something we can look into, don’t hesitate to make an issue on the diff repo with your ideas and examples of what it would look like!
There are links to the diffs, but they might be a bit tricky to see
If you have ideas for how to improve the UI and make the diffs easier to see, please make an issue on the hexpm repo

I have checked it out, and for now one thing brought my attention - why fire
git diffto compare two projects? Now I am thinking about writing diff algorithm in Elixir or to bring it via NIF toxdiff.wojtekmach
Using
git diffwas a pragmatic choice with libraries support (we use git_diff | Hex to parse hunks to provide better user experience).I think a pure Elixir solution would be interesting and in fact that could be a great default for another tool:
mix hex.package diff(we couldn’t use a NIF there)hauleth
xdiffis library used by Git, so there should be no difference. By the way, do you use regular algorithm or patience? Patience one should give slightly better results while being slightly more computationally expensive (but caching should made it neglible difference).I will try to write something like that in some spare time.
