Subject: bug#28615: 25.3; rgrep, grep-read-files confusingly completes file names
Date: Wed, 27 Sep 2017 00:01:56 -0700 [thread overview]
Message-ID: <CAJr1M6fy+wRfbHn=iXDWAaX7zmqJ72VWRy-pOHuDkca5=Cr6ig@mail.gmail.com> (raw)
rgrep uses grep-read-files to read a filename as the second argument.
However, rgrep cannot actually accept a filename as the second argument.
For example, this is a normal rgrep call
(rgrep "foo" "*.el" "/some/dir/" nil)
"*.el" is read with grep-read-files, which uses filename completion.
However, actually entering a filename doesn’t really work
(rgrep "foo" "foo/*.el" "/some/dir/" nil)
(rgrep "foo" "foo/bar.el" "/some/dir/" nil)
The second argument is passed to the find program as an -iname argument
as a glob, which matches against strictly the filename (e.g., like
file-name-nondirectory) and not the path.
There are a few points that could be improved here.
1. The grep-read-files prompt is confusing. The prompt is: "Search for
\"foo\" in files: ". It is not clear that this is asking for a filename
glob.
2. grep-read-files uses filename completion, which suggests that the
user should enter a filename. This is very misleading as most paths
will fail to work, passing a filename without a slash will likely not
work as the user would expect, and almost certainly a glob would be the
desired input.
