Trouble Creating Diff for Tmux 2.1 Patch

[indiesquidge]

The Tmux 2.1 update broke a few things that I regularly use, and I would like to create my own patch/diff for my installed package.

I have been reading about creating patches, but I don't know if I fully understand what to do with this diff to fix the issue. I have created the diff, but every time I run

brew install --interactive --git tmux 

make the diff changes, and

git diff >> /usr/local/Library/Formula/tmux.rb 

I get Error: Empty installation when I exit, and the package is nowhere to be found. What am I missing that is causing this issue?

I have downloaded the Tmux 2.0 tar file and gotten that to work manually based on Tmux's readme, but I would rather use Homebrew to install tmux 2.1 and patch this one thing. Any help would be appreciated.

The brew install --interactive --git tmux is used to create the diff; if you already have one you don’t need this.

At the end of the formula add a line with __END__ followed by the patch. See an example here.

Then at the top of the formula, before def install, add patch :DATA. You can then try to brew install tmux. If it works, add a comment above patch :DATA explaining why it’s necessary and submit a pull-request 😉

@bfontaine, ah, that makes sense. Thank you for explaining. Unfortunately, after I created the correct diff and installed tmux, it seems that nothing has changed :(

I'm guessing it's a problem with the diff itself, so I'd have to take my issue back over to the tmux issue page?

@bfontaine, so I got it to work with brew install --build-from-source tmux. I will update the file with a comment on the patch and create a PR. Thank you for your help :)
