Compare without args

[eitah]

Could it assume current branch and current default if not supplied? I made an alias on my local machine but maybe i didn't understand what your intention was here.

you need to install the gh-browse-compare extension

compare() {
echo gh compare "$(git config --get init.defaultBranch)" to "$(git branch --show-current)"
gh compare "$(git config --get init.defaultBranch)".."$(git branch --show-current)"
}
