[PATCH 0/2] ls-files: align format atoms with git ls-tree

[ZheNing Hu via GitGitGadget]

Users sometimes want all format atoms of git ls-files --format to be
compatible with the format atoms of git ls-tree --format [1]. However, git
ls-files --format lacks the %(objecttype) and %(objectsize),
%(objectsize:padded) atoms compared to git ls-tree --format, causing
incompatibility. Therefore, these atoms are added to the --format of git
ls-files to resolve the issue of incompatibility.

%(objecttype): get the object type of the file which is recorded in the
index. %(objectsize): get the object size of the file which is recorded in
the index, ("-" if the object is a commit or tree). %(objectsize:padded):
same as %(objectsize), but with a padded format.

v1: add %(objecttype) and %(objectsize) atos to git ls-files --format.

[PATCH 1/2] ls-files: add %(objecttype) atom to format option

[ZheNing Hu via GitGitGadget]

From: ZheNing Hu <adlternative@gmail.com>

Sometimes users may want to align the feature of
`git ls-files --format` with that of `git ls-tree --format`,
but the %(objecttype) atom is missing in the format option
of git ls-files compared to git ls-tree.

Therefore, the %(objecttype) atom is added to the format option
of git ls-files, which can be used to obtain the object type
of the file which is recorded in the index.

"Sometimes users may want to" sounds a bit awkward; even if no user
notices that the two very similar commands supports different subset
of the vocabulary without good reason, wouldn't we want to align the
feature set of these two commands?

And from that point of view, this conclusion has a bit more to think
about.  Is the %(objecttype) singled out here only because somebody
happened to have complained on the list, or did somebody went into
the list of supported atoms between two commands and considered what
is missing from one but is supported by the other, and concluded that
only adding this one atom to ls-files would make the two consistent?

I would not complain if it were the former, but it must be explained
here in the proposed log message.  That would encourage others to do
a follow-on work to complete the comparison to fill the gaps on the
both sides.  If it were the former, saying so explicitly in the
proposed log message will save others---otherwise they may try to do
the comparison themselves only to find that this was the last one
remaining discrepancy.

I think the original requirement is that users wanted to obtain a similar
output format to the default output format of git ls-tree directly through
git ls-files --format="%(objectmode) %(objecttype) %(objectname)%x09%(path)",
but found that the corresponding functionality was missing.

However, from a deeper perspective, the results displayed by git ls-files
for the index and git ls-tree -r for the tree are very similar. Making
git ls-files compatible with the atoms of git ls-tree can provide a
unified view here,
and can also be used for some conversion between the index and tree, such as
git ls-files --format | git mktree.

[PATCH 2/2] ls-files: add %(objectsize) atom to format option

[ZheNing Hu via GitGitGadget]

From: ZheNing Hu <adlternative@gmail.com>

Sometimes users may want to align the feature of
`git ls-files --format` with that of `git ls-tree --format`,
but the %(objectsize) and %(objectsize:padded) are missing
in the format option of git ls-files compared to git ls-tree.

Therefore, the %(objecttsize) atom is added to the format
option of git ls-files, which can be used to obtain the
object size of the file which is recorded in the index.
("-" if the object is a `commit` or `tree`) It also
supports a padded format of size with %(objectsize:padded).

Exactly the same comment applies here to this patch.

If these two are the only ones missing and after these patches
ls-files and ls-tree become equivalent in the support of atoms,
then explaining that in the log message and do these in a single
patch would make the most sense.

Thanks.

[PATCH v2] ls-files: aligin format atoms wtih ls-tree

[ZheNing Hu via GitGitGadget]

From: ZheNing Hu <adlternative@gmail.com>

"git ls-files --format" can be used to format the output of
multiple file entries in the index, while "git ls-tree --format"
can be used to format the contents of a tree object. However,
the current set of %(objecttype), "(objectsize)", and
"%(objectsize:padded)" atoms supported by "git ls-files --format"
is a subset of what is available in "git ls-tree --format".

Users sometimes need to establish a unified view between the index
and tree, which can help with comparison or conversion between the two.

Therefore, this patch adds the missing atoms to "git ls-files --format".
"%(objecttype)" can be used to retrieve the object type corresponding
to a file in the index, "(objectsize)" can be used to retrieve the
object size corresponding to a file in the index, and "%(objectsize:padded)"
is the same as "(objectsize)", except with padded format.
