List only local branches when autocompleting git checkout (Zsh)

git-zsh-checkout-autocomplete-local-only.md

git config --global alias.checkoutr checkout
$EDITOR /usr/local/share/zsh/site-functions/git-completion.bash

...and then modify the file as follows...

-__gitcomp_nl "$(__git_refs '' $track)"
+if [ "$command" = "checkoutr" ]; then
+    __gitcomp_nl "$(__git_refs '' $track)"
+else
+    __gitcomp_nl "$(__git_heads '' $track)"
+fi

... and source your shell (source ~/.bashrc / source ~/.zshrc...).

Use git checkoutr for the default behavior and git checkout (or just gco) for browsing only local branches. Credits to http://cmetcalfe.ca/blog/git-checkout-autocomplete-local-branches-only.html.

git config --global --type=bool checkout.guess false

That does the trick, thanks!

I finally figured this out for anyone wondering. I had to change the implementation defined within the gitfast plugin directory.

For me this was located here:
~/.oh-my-zsh/plugins/gitfast/git-completion.bash

Changes that work

The suggestion by @ekoneko to remove $dwim_opt

                else
-                       __git_complete_refs $dwim_opt --mode="refs"
+                       __git_complete_refs --mode="heads"
                fi

Changes that do not work

Note you do NOT need to set checkout.guess = false in your .gitconfig. I found by doing so, it actually broke the ability to use git checkout for local search and git checkoutr for remote search.
