From 52fd972d5922c95b44e49cd736f67d495a0175f1 Mon Sep 17 00:00:00 2001 From: Felipe Contreras Date: Tue, 10 May 2011 15:20:39 +0300 Subject: [PATCH] git-completion: fix regression in zsh support MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The zsh support of git-completion script in contrib/ is broken for current versions of zsh, and does not notice when there's a subcommand. For example: "git log origi" gives no completions because it would try to find a "git origi..." command. This will be fixed by zsh 4.3.12, but for now we can workaround it by backporting the same fix as zsh folks implemented. The problem started after commit v1.7.4-rc0~11^2~2 (bash: get --pretty=m completion to work with bash v4), which introduced _get_comp_words_by_ref() that comes from bash-completion[1] scripts, and relies on the 'words' variable. However, it turns out 'words' is a special variable used by zsh completion. From zshcompwid(1): [...] the parameters are reset on each function exit (including nested function calls from within the completion widget) to the values they had when the function was entered. As a result, subcommand words are lost. Ouch. This is now fixed in the latest master branch of zsh[2] by simply defining 'words' as hidden (typeset -h), which removes the special meaning inside the emulated bash function. So let's do the same. Jonathan Nieder helped on the commit message.
