Subject: [PATCH v3 2/8] config: replace 'value_regex' with 'value_pattern'
Date: Wed, 25 Nov 2020 22:12:50 +0000	[thread overview]
Message-ID: <f135b001ad911c079b0754c61e2179277ce37e0f.1606342377.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.796.v3.git.1606342376.gitgitgadget@gmail.com>

From: Derrick Stolee <dstolee@microsoft.com>

The 'value_regex' argument in the 'git config' builtin is poorly named,
especially related to an upcoming change that allows exact string
matches instead of ERE pattern matches.

Perform a mostly mechanical change of every instance of 'value_regex' to
'value_pattern' in the codebase. This is only critical for documentation
and error messages, but it is best to be consistent inside the codebase,
too.

For documentation, use 'value-pattern' which is better punctuation. This
affects Documentation/git-config.txt and the usage in builtin/config.c,
which was already mixed between 'value_regex' and 'value-regex'.

I gave some thought to leaving the value_regex variables inside config.c
that are regex_t pointers. However, it is probably best to keep the name
consistent with the rest of the variables.

This does not update the translations inside the po/ directory, as that
creates conflicts with ongoing work. The input strings should
automatically update through automation, and a few of the output strings
currently use "[value_regex]" directly.

 Multiple lines can be added to an option by using the `--add` option.
