Back in 2012 I argued [1] for the introduction of a helper that would allow users to specify aliases like: git_complete gf git_fetch There was pushback because there was no clear guideline for public functions (git_complete vs. _git_complete vs. _GIT_complete), and some aliases didn't actually work. Fast-forward to 2020, and there's still no guideline for public functions, and those aliases still don't work (even though I sent the fixes). This has not prevented people from using this function that is clearly needed to setup custom aliases [2], and in fact that's the recommended way since there's no other. But it is cumbersome that the user must type: __git_complete gf _git_fetch Or worse: __git_complete gk __gitk_main 8 years is more than enough time to stop waiting for the perfect to come; let's define a public function (with the same name) that is actually user-friendly: __git_complete gf git_fetch __git_complete gk gitk While also maintaining backwards compatibility. Changes since v2: * Improved the safety of __git_have_func with suggestions from René Scharfe * Added documentation to the top of git-completion.bash [1] https://lore.kernel.org/git/1334524814-13581-1-git-send-email-felipe.contreras@xxxxxxxxx/ [2] https://stackoverflow.com/questions/342969/how-do-i-get-bash-completion-to-work-with-aliases Felipe Contreras (4): completion: bash: add __git_have_func helper completion: bash: improve function detection test: completion: add tests for __git_complete completion: add proper public __git_complete contrib/completion/git-completion.bash | 50 ++++++++++++++++++++------ t/t9902-completion.sh | 20 +++++++++++ 2 files changed, 60 insertions(+), 10 deletions(-) Range-diff against v2: 1: 0993732142 = 1: 0993732142 completion: bash: add __git_have_func helper -: ---------- > 2: 6a3fe8b79b completion: bash: improve function detection 2: 7918c34d0e = 3: b211eebc0d test: completion: add tests for __git_complete 3: 8a6cc52063 ! 4: a5bfe5376b completion: add proper public __git_complete @@ Commit message Signed-off-by: Felipe Contreras <felipe.contreras@xxxxxxxxx> ## contrib/completion/git-completion.bash ## +@@ + # tell the completion to use commit completion.
