[PATCH] completion: Make sed command that generates config-list.h portable.

[Collin Funk]

The OpenBSD 'sed' command does not support '\n' to represent newlines in
sed expressions. This leads to the follow compiler error:

    In file included from builtin/help.c:15:
    ./config-list.h:282:18: error: use of undeclared identifier 'n'
            "gitcvs.dbUser",n       "gitcvs.dbPass",
                            ^
    1 error generated.
    gmake: *** [Makefile:2821: builtin/help.o] Error 1

We can use a variable that expands to a newline to do this portably.

This portably issue was introduced in e1b81f54da (completion: take into
account the formatting backticks for options, 2025-03-19)

Thanks. This was the last piece I was just going to look into, but you

Hello,

I was on this issue here: 
https://github.com/git/git/commit/e1b81f54da80267edee2cb8fd0d0f75f03023019

Your proposed fix is interesting in that it does not spawn an additional 
process, but it does not work for me (debian sh = dash).

If you'd like to test your patch on different systems and happen to have a

builds on several targets.

Thank you very much for checking! On my system /bin/sh is linked to
/bin/bash, so I did not notice.

I will send a V2 that works with the dash packaged by Fedora 42. It
produces the same output as bash and works on OpenBSD.

The OpenBSD 'sed' command does not support '\n' to represent newlines in

FYI I pushed your patch to 
https://github.com/gitgitgadget/git/pull/1930/

It seems to be passing, although it's not very readable.

Your commit message has some issues:

 * upper case in "Make": prefixed commits message must be lower case
 * to be correct, the bug was already there at the first introduction of the 
generate-configlist.sh script (3ac68a9). The '\n' was there, and the generated 
.h file had two wrong strings such as
"gitcvs.dbUserngitcvs.dbPass" . My patch only put it in light by breaking the 
build.

Maybe an alternative way of fixing the issue is to just rework the 
documentation on the two spots where a comma is used and put each config 
variable on its own line.

What do you think?

Regarding readability, it is not any worse than it was originally. But
maybe that is because you are much better at sed than me. :)

But we could put configurations on seperate lines like so:

    	and 'tformat:<string>'.  When '<format>' is none of the above,
    	and has '%placeholder' in it, it acts as if
    	'--pretty=tformat:<format>' were given.

Then go back to the simpler sed expression before your most recent
commit. I will wait for others thoughts before posting v3.

Thanks,
Collin

Thanks for checking.

Although, I now realize my explination was slightly incorrect. Some of
the referenced commit is still needed for formatting, but we can remove
part of the expression that causes the problem.

I posted V3 so others can check.

As long as we warn our documenters that comma separated entries are
forbidden in our documentation (even though AsciiDoc and Asciidoctor
may allow them), it would be the simplest.  The question is where.

Perhaps the tail end of the CodingGuidelines document where we
already have write-up for markups?

Thanks.

[PATCH] CodingGuidelines: document formatting required by generate-configlist.sh.

Document that related `git config` variables should be placed

As `core.varN` in the above example are all what the end-user would
give literally, just like `git config` command name in the first
sentence, they should be marked up as literal strings, i.e.

    ... For example, do not write this:

    `core.var1`, `core.var2`::
	Description common to `core.var1` and `core.var2`.
	
    Instead write this:

    `core.var1`::
    `core.var2`::
	Description common to `core.var1` and `core.var2`.

> +This format is required for the `generate-configlist.sh` script to

It is not wrong per-se, but this tempts people to "fix" the
generate-configlist.sh script so that it can grok the comma
separated list "again".  And when that fix is done and reviewed
carelessly, we'd again break some implementations of sed the same
way and we will come back full circle ;-)


When we standardized writing negatable options this way

    `--option`::
    `--no-option`::
	Description of `--option` that can be turned off with
	`--no-option`.

instead of

    `--[no-]option`::
	Description of `--option` that can be turned off with
	`--no-option`.

we explained that the reason why we want to do so is because it is
easier to "grep".  Does this "do not comma-list variables, but list
them one per line" also give us better greppability, and if so we
want to explain that way, perhaps?

    $ git grep '`core\.var1`::' Documentation/config/

Thanks.

This markup is different than what is used in
Documentation/config/*.adoc though. Here is just one example:

    $ head -n 3 Documentation/config/core.adoc 
    core.fileMode::
    	Tells Git if the executable bit of files in the working tree
    	is to be honored.

That was my reasoning for writing it how I did in the patch. Are you
saying that all of these should be changed? I do not have any experience
with AsciiDoc so I am not sure if that is correct.

Yes, that is a good side affect of the change that can be documented.

I will send V2 after clarification on the other point.

We are updating them gradually while avoiding collisions with
patches that do other "real" work; see many recent patches to
Documentation/config/ area by Jean-Noël Avila for more, e.g.
d30c5cc4 (doc: convert git-mergetool options to new synopsis style,
2025-05-25).

Thanks.

Ah, okay. I must have just looked at files that have not been touched in
some time.

I sent V2 which uses the example you sent [1]. Feel free to add yourself
as 'Co-authored-by:'.

Thanks,

[PATCH v2] CodingGuidelines: document formatting of similar config variables.

[Collin Funk]

Document that related `git config` variables should be placed
one-per-line instead of separated by commas.

[PATCH v3] completion: make sed command that generates config-list.h portable.

[Collin Funk]

The OpenBSD 'sed' command does not support '\n' to represent newlines in
sed expressions. This leads to the follow compiler error:

    In file included from builtin/help.c:15:
    ./config-list.h:282:18: error: use of undeclared identifier 'n'
            "gitcvs.dbUser",n       "gitcvs.dbPass",
                            ^
    1 error generated.
    gmake: *** [Makefile:2821: builtin/help.o] Error 1

We can fix this by documenting related configuration variables
one-per-line instead of listing them separated by commas. This allows us
to remove the unportable part of the sed expression in
generate-configlist.sh.
