[PATCH 00/22] Mark more strings for translation

[PATCH 00/22] Mark more strings for translation

[Nguyễn Thái Ngọc Duy]

I originally wanted to have a look regularly at what's in 'pu', catch
translatable strings that are not marked so and ask for updates. But I
failed horribly at that, so for this cycle I just looked at all the
changes between the last release and master and marked strings.

This series probably won't end up in 2.18 because now is probably too
late for big changes, which is fine.

[PATCH 02/22] archive-zip.c: mark more strings for translation

[Nguyễn Thái Ngọc Duy]

One 'P' is lower cased because we normally start an error message with
lowercase.

Off topic. Brian, do we have a common term to use here (i.e. in user
facing messages) instead of "SHA1" after we move away from it? Is it
still "object name", or "hash" or some other fancy term?

You could say "object ID" or "object" here.  It should be clear from
context what that means.  I tend to use "hash" for things which are not
necessarily object IDs (e.g. pack hash).

Perhaps?

    cannot overwrite multiple values with a single value;
    use a regexp, --add or --replace-all to change %s

In other patches, you dropped the trailing "!"; perhaps do so for
these two also?

Maybe even:

    die(_("no such section: %s", whatever);

Though, that may be out of scope of this patch series.

I'll probably leave these multi sentence errors alone. There's some
work going on about these multiple sentence messages. We can come back
after that series settles.

Might as well do it while I'm at it. I'll do it in a separate patch
though and try to keep these i18n patches about _() only.

[PATCH 05/22] builtin/pack-objects.c: mark more strings for translation

[Nguyễn Thái Ngọc Duy]

Most of these are straight forward. GETTEXT_POISON does catch the last
string in cmd_pack_objects(), but since this is --progress output, it's
not supposed to be machine-readable.

It's kind of weird to drop capitalization of the first sentence but
not the second. Also, you dropped trailing "!" in some other patches;

    the original commit '%s' has a gpg signature;
    the signature will be removed in the replacement commit

In other messages in this patch, you dropped the period at the end of
the message. Perhaps do so here too.

The change from '$(cat e)' to bare 'e' caught me off guard for a
moment, but use of test_i18ngrep explains it. Okay.

I hadn't seen test_i18ngrep take argument -q elsewhere, so I wondered
if it handled it correctly. Checking the implementation, I see that it
does pass it along to the underlying grep. Okay.

I also wondered briefly if it made sense to drop -q here since it
doesn't necessarily help debugging the test upon failure, but I
suppose such a change is outside the scope of this patch series, so
probably better not to.

Did you want to downcase "Could" for consistency with other error
messages, or was this left as-is intentionally?

I'm not sure. Others start with a prefix (like "error:",
"warning:"....). This is a bit different and makes me hesitate.

Yep, I realized after hitting Send that this wasn't an error/warning
message so probably shouldn't be changed.

The above three are indicative of programmer error, aren't they? If
so, they ought not be translated (and perhaps changed to BUG at some
point).

Perhaps drop the trailing period as you did in other cases.

Did you want to downcase "No" or just didn't bother since it's not
intended for end-user?

It looks like most callers of transport_get() won't pass NULL for
'remote' so this makes sense as a BUG(). A couple callers,
archive.c:run_remote_archiver() and fetch-object.c:fetch_refs(), get
the remote via remote_get() but don't check for NULL before
dereferencing it (before even calling this function), so will crash if
remote_get() ever returns NULL (assuming that it ever could in those
cases).

    unknown mandatory capability '%s'; this remote
    helper probably needs newer version of Git

[PATCH v2 00/23] Mark strings for translation

[Nguyễn Thái Ngọc Duy]

v2 changes

- fix one _() (was "()" by accident)
- improve some error messages while i'm making changes
- restore some multi-sentence messages back

All non-_() changes are now collected in the first patch.

[PATCH v2 01/23] Update messages in preparation for i18n

[Nguyễn Thái Ngọc Duy]

Many messages will be marked for translation in the following
commits. This commit updates some of them to be more consistent and
reduce diff noise in those commits. Changes are

- keep the first letter of die(), error() and warning() in lowercase
- no full stop in die(), error() or warning() if it's single sentence
  messages
- indentation
- some messages are turned to BUG(), or prefixed with "BUG:" and will
  not be marked for i18n
- some messages are improved to give more information
- some messages are broken down by sentence to be i18n friendly
- the trailing \n is converted to printf_ln if possible
- errno_errno() is used instead of explicit strerror()
