Currently `git fast-import -h` shows the following on a single line:
usage : git fast-import [--date-format=<f>] [--max-pack-size=<n>] \
[--big-file-threshold=<n>] [--depth=<n>] \
[--active-branches=<n>] \
[--export-marks=<marks.file>]
This output has a number of issues like:
- It's missing a lot of options.
- It's not consistent with the SYNOPSIS section of the doc.
- With `--help-all` instead of `-h` additional hidden options should
be shown, but that's not the case.
- It's not standard style anymore.
- Most other Git commands show additional lines for most of the
options they support.
Also while most commands use the parse-options API to handle their
options, "builtin/fast-import.c" still doesn't use it.
Let's improve on that by using the parse-options API to display the
options when `-h` and `--help-all` are used.
While at it, let's make the SYNOPSIS section of
"Documentation/git-fast-import.adoc" consistent with the new usage
string.
This deliberately leaves it to future work to also use the
parse-options API to actually parse the options.

The output of `git fast-export -h` currently starts with:
usage: git fast-export [<rev-list-opts>]
while the SYNOPSIS section in this command's documentation shows:
'git fast-export' [<options>] | 'git fast-import'
Let's make both of these consistent with each other and with other Git
commands by describing the arguments with:
[<options>] [<revision-range>] [[--] <path>...]
This takes into account the following:
- `git fast-export` accepts both rev-list arguments and a number of
genuine options of its own (--[no-]progress, --[no-]signed-tags,
--[no-]signed-commits, etc).
- `git fast-export` was the only command using `[<rev-list-opts>]`
while many other commands describe their revision arguments as
`[<revision-range>] [[--] <path>...]`.
- In the DESCRIPTION section of the documentation, it's already
mentioned several times that the output should eventually be fed to
`git fast-import`.
This also enables us to remove fast-export from
"t/t0450/adoc-help-mismatches".

Since c39fffc1c90 (tests: start asserting that *.txt SYNOPSIS matches -h
output, 2022-10-13), the manual page for 'git multi-pack-index' has a
SYNOPSIS section which differs from 'git multi-pack-index -h'.
Correct this while also documenting additional options accepted by the
'write' sub-command.

Update the usage string of `git bisect` and documentation to match each
other. While at it, also:
1. Move the synopsis of `git bisect` subcommands to the synopsis
section, so that the test `t0450-txt-doc-vs-help.sh` can pass.
2. Document the `git bisect next` subcommand, which exists in the code
but is missing from the documentation.

Test updates.
* tc/t0450-harden:
t0450: add allowlist for builtins with missing .adoc
t0450: fix test for out-of-tree builds
|
|
Before we were silently skipping all builtins that don't have a matching
.adoc file. This is overly loose and might skip documentation files
when it shouldn't, for example when there was a typo in the filename.
To ensure no new builtins are added without documentation, add an
allowlist: t0450/adoc-missing. In this file only builtin commands that
do *not* have a corresponding .adoc file shall be listed. If there is a
mismatch, fail the test. This should force future contributions to
either add an .adoc, or add the builtin name to the allowlist file.

Usage string for `git for-each-ref` was out of sync with its official
documentation. The test `t0450-txt-doc-vs-help.sh` was marked as broken
due to this.
Update the usage string to match the documentation. This allows the test
to pass, so remove the corresponding 'known breakage' marker from the
test file.

The t0450 test script verifies that builtin usage matches the synopsis
in the documentation. Adjust the builtin to match and then remove 'git
pack-objects' from the exception list.

After 1f010d6bdf (doc: use .adoc extension for AsciiDoc files,
2025-01-20), we no longer matched any files in this test. The result is
that we did not test for mismatches in the documentation and --help
output.
Adjust the test to look at the renamed *.adoc files.

The new '--name-hash-version' option for 'git repack' is a simple
pass-through to the underlying 'git pack-objects' subcommand. However,
this subcommand may have other options and a temporary filename as part
of the subcommand execution that may not be predictable or could change
over time.
The existing test_subcommand method requires an exact list of arguments
for the subcommand. This is too rigid for our needs here, so create a
new method, test_subcommand_flex. Use it to check that the
--name-hash-version option is passing through.
Since we are modifying the 'git repack' command, let's bring its usage
in line with the Documentation's synopsis. This removes it from the
allow list in t0450 so it will remain in sync in the future.

Until now, `git config -h` would have printed help for the old-style
syntax. Now that all modes have proper subcommands though it is
preferable to instead display the subcommand help.
Drop the `NO_INTERNAL_HELP` flag to do so. While at it, drop the help
mismatch in t0450 and add the `--get-colorbool` option to the usage such
that git-config(1)'s synopsis and `git config -h` match.

There's been a lot of incremental effort to make the SYNOPSIS output
in our documentation consistent with the -h output,
e.g. cbe485298bf (git reflog [expire|delete]: make -h output
consistent with SYNOPSIS, 2022-03-17) is one recent example, but that
effort has been an uphill battle due to the lack of regression
testing.
This adds such regression testing, we can parse out the SYNOPSIS
output with "sed", and it turns out it's relatively easy to normalize
it and the "-h" output to match on another.
We now ensure that we won't have regressions when it comes to the list
of commands in "expect_help_to_match_txt" below, and in subsequent
commits we'll make more of them consistent.
The naïve parser here gets quite a few things wrong, but it doesn't
need to be perfect, just good enough that we can compare /some/ of
this help output. There's no cases where the output would match except
for the parser's stupidity, it's all cases of e.g. comparing the *.txt
to non-parse_options() output.
Since that output is wildly different than the *.txt anyway let's
leave this for now, we can fix the parser some other time, or it won't
become necessary as we'll e.g. convert more things to using
parse_options().
Having a special-case for "merge-tree"'s 1f0c3a29da3 (merge-tree:
implement real merges, 2022-06-18) is a bit ugly, but preferred to
blessing that " (deprecated)" pattern for other commands. We'd
probably want to add some other way of marking deprecated commands in
the SYNOPSIS syntax. Syntactically 1f0c3a29da3's way of doing it is
indistinguishable from the command taking an optional literal
"deprecated" string as an argument.
Some of the issues that are left:
* "git show -h", "git whatchanged -h" and "git reflog --oneline -h"
all showing "git log" and "git show" usage output. I.e. the
"builtin_log_usage" in builtin/log.c doesn't take into account what
command we're running.
* Commands which implement subcommands such as like
"multi-pack-index", "notes", "remote" etc. having their subcommands
in a very different order in the *.txt and *.c. Fixing it would
require some verbose diffs, so it's been left alone for now.
* Commands such as "format-patch" have a very long argument list in
the *.txt, but just "[<options>]" in the *.c.
What to do about these has been left out of this series, except to
the extent that preceding commits changed "[<options>]" (or
equivalent) to the list of options in cases where that list of
options was tiny, or we clearly meant to exhaustively list the
options in both *.txt and *.c.
