[PATCH] [GSOC] pretty: provide human date format

[ZheNing Hu via GitGitGadget]

From: ZheNing Hu <adlternative@gmail.com>

Add the placeholders %ah and %ch to format author date and committer
date, like --date=human does, which provides more humanity date output.

    [GSOC] pretty: provide human date format
    
    Reasons for making this patch: --date=human has no corresponding
    --pretty option.
    
    Although --date=human with --pretty="%(a|c)d" can achieve the same
    effect with --pretty="%(a|c)h", but it can be noticed that most time
    formats implement the corresponding option of --pretty, such as
    --date=iso8601 can be replaced by --pretty=%(a|c)i, so add
    "--pretty=%(a|c)h" seems to be a very reasonable thing.

I don't see a reason why this shouldn't exist, and the patch that you
wrote below looks pretty good to me.

To refresh my memory on if you had missed any spots, I followed
0df621172d (pretty: provide short date format, 2019-11-19) as an
example. You did a fine job here, and I don't think this patch is
missing anything.

Just to make sure I understand what you wrote: you're saying that the
pretty formats "%ah" and "%ch" that you propose here could be achieved
with --date=human and --pretty="%ad". Makes sense, but I agree that your
point about --date=iso8601 having a built-in pretty atom makes the case
for having "%ah" and "%ch".

There's no sorting here, so this place (at the bottom of the author-date
placeholders) seems just as good as any.

Likewise. The rest all looks good to me, too.

Yes, I saw René Scharfe's (have --cc) patch and learned handle way from it.

Yes, I tried to explain that "%(a|c)h" makes sense.

An example may be useful. There's no other mention of human date style
in the pretty-formats doc. Or a link to the definitive man page.

Thanks for the suggestion. Note that the explanation here is relatively small,
and human style has many different situations, so I may just go to link it to
`rev-list-option.txt`, This is more convenient than showing multiple situations'
examples.

[PATCH v2] [GSOC] pretty: provide human date format

[ZheNing Hu via GitGitGadget]

From: ZheNing Hu <adlternative@gmail.com>

Add the placeholders %ah and %ch to format author date and committer
date, like --date=human does, which provides more humanity date output.

    [GSOC] pretty: provide human date format
    
    Reasons for making this patch: --date=human has no corresponding
    --pretty option.
    
    Although --date=human with --pretty="%(a|c)d" can achieve the same
    effect with --pretty="%(a|c)h", but it can be noticed that most time
    formats implement the corresponding option of --pretty, such as
    --date=iso8601 can be replaced by --pretty=%(a|c)i, so add
    "--pretty=%(a|c)h" seems to be a very reasonable thing.
    
    Change from v1: add %(a|c)h link to rev-list-options.txt.

Also. Is this right? Shouldn't it just link to the dashed git- command's
man page, rather than the file, i.e.

[PATCH 0/2] pretty tests: --date/format test improvements

[Ævar Arnfjörð Bjarmason]

A couple of trivial changes noticed when reviewing the "pretty:
provide human date format" series.

Ævar Arnfjörð Bjarmason (2):
  pretty tests: simplify %aI/%cI date format test
  pretty tests: give --date/format tests a better description

[PATCH 1/2] pretty tests: simplify %aI/%cI date format test

[Ævar Arnfjörð Bjarmason]

Change a needlessly complex test for the %aI/%cI date
formats (iso-strict) added in 466fb6742d7 (pretty: provide a strict
ISO 8601 date format, 2014-08-29) to instead use the same pattern used
to test %as/%cs since 0df621172d8 (pretty: provide short date format,
2019-11-19).

LGTM.

I wonder if these format shortcut tests that now look so regular should
be put into a loop with a few suitable loop parameters?

While these two must show the same output, I wonder how much value
we are getting out of them.  Don't they end up exercising pretty
much the same codepath?

Not that I think the original is any better at all, though ;-)

[PATCH 2/2] pretty tests: give --date/format tests a better description

[Ævar Arnfjörð Bjarmason]

Change the description for the --date/format equivalency tests added
in 466fb6742d7 (pretty: provide a strict ISO 8601 date format,
2014-08-29) and 0df621172d8 (pretty: provide short date format,
2019-11-19) to be more meaningful.

This allows us to reword the comment added in the former commit to
refer to both tests, and any other future test, such as the in-flight
--date=human format being proposed in [1].

Notice that you modified the title of the test
`short date`--->  `--date=short %ad%cd is the same as %as%cs`,
then the `human date` patch I am working should also do the similar
things as you do here?

[PATCH v3] [GSOC] pretty: provide human date format

[ZheNing Hu via GitGitGadget]

From: ZheNing Hu <adlternative@gmail.com>

Add the placeholders %ah and %ch to format author date and committer
date, like --date=human does, which provides more humanity date output.

Signed-off-by: ZheNing Hu <adlternative@gmail.com>
---
    [GSOC] pretty: provide human date format
    
    Reasons for making this patch: --date=human has no corresponding
    --pretty option.
    
    Although --date=human with --pretty="%(a|c)d" can achieve the same
    effect with --pretty="%(a|c)h", but it can be noticed that most time
    formats implement the corresponding option of --pretty, such as
    --date=iso8601 can be replaced by --pretty=%(a|c)i, so add
    --pretty=%(a|c)h seems to be a very reasonable thing.
    
    Change from v2: change %(a|c)h link to git-rev-list and change to more
    suitable test title.

[PATCH v4] [GSOC] pretty: provide human date format

[ZheNing Hu via GitGitGadget]

From: ZheNing Hu <adlternative@gmail.com>

Add the placeholders %ah and %ch to format author date and committer
date, like --date=human does, which provides more humanity date output.

    [GSOC] pretty: provide human date format
    
    Reasons for making this patch: --date=human has no corresponding
    --pretty option.
    
    Although --date=human with --pretty="%(a|c)d" can achieve the same
    effect with --pretty="%(a|c)h", but it can be noticed that most time
    formats implement the corresponding option of --pretty, such as
    --date=iso8601 can be replaced by --pretty=%(a|c)i, so add
    --pretty=%(a|c)h seems to be a very reasonable thing.
    
    Change from v3: Fix format errors.
