Subject: [PATCH v6 0/7] Teach '--column' to 'git-grep(1)'
Date: Fri, 11 May 2018 20:10:57 -0700 [thread overview]
Message-ID: <cover.1526094383.git.me@ttaylorr.com> (raw)
In-Reply-To: <20180421034530.GB24606@syl.local>
Hi,
Attached is my sixth re-roll of a series to add '--column' to 'git
grep'.
The main change since v5 is supporting --column with queries containing
--and, --or, or --not. Previously, I had chosen to die() in this case
since there isn't always a good answer to "what is the first column of
<complicated expression>?" but have gone back on this for two reasons:
1. It is important not to regress calls to git-jump/contrib/git-jump
that contain --and, --or, or --not.
2. It is not that hard to detect the absence of column data in scripts.
Likewise, git-jump will happily accept lines with or without
columnar information, and Vim will accept it as-is.
So, let's support --column and only die() when also given
--invert-match. When we don't have a good answer, print nothing.
Thanks,
Taylor
