[PATCH v11 0/5][BZ 10871] Month names in alternative grammatical case

[Rafal Luzynski]

As requested by Carlos, [1] this is the 11th version of my patches.
This version is actually the same as the previous one, [2] it is only
rebased to the current master.

Again, note that this set contains only patches 1/5, 3/5, and 5/5.
The patches 2/5 and 4/5 contain updates to the generated files and
ChangeLog, they should be eventually squashed but not posted to this list.

As we are short of time, these patches are not attached to bugzilla. [3]

Additionally, I'm adding the locale data patch for pl_PL.  It may be
considered as a separate patch but I am going to push it as soon as all
other patches are accepted.  This patch is already accepted by the Polish
translation team.  Note that the change introduced by this set of patches
will be visible only in locales which actually contain different "mon"
and "alt_mon" arrays.

Regards,

Rafal

[PATCH v11 1/5] Implement alternative month names (bug 10871).

[Rafal Luzynski]

Some languages (Slavic, Baltic, etc.) require a genitive case of the
month name when formatting a full date (with the day number) while
they require a nominative case when referring to the month standalone.
This requirement cannot be fulfilled without providing two forms for
each month name.  From now it is precised that nl_langinfo(MON_1)
series (up to MON_12) and strftime("%B") generate the month names in
the grammatical form used when the month forms part of a complete date.
If the grammatical form used when the month is named by itself is needed,
the new values nl_langinfo(ALTMON_1) (up to ALTMON_12) and
strftime("%OB") are supported.  This new feature is optional so the
languages which do not need it or do not yet provide the updated
locales simply do not use it and their behaviour is unchanged.

	[BZ #10871]
	* locale/C-time.c: Add alternative month names, define them as the
	same as mon explicitly.
	* locale/categories.def: alt_mon and wide-alt_mon added.
	* locale/langinfo.h [__USE_GNU]: New public symbols ALTMON_1,
	ALTMON_2, ALTMON_3, ALTMON_4, ALTMON_5, ALTMON_6, ALTMON_7,
	ALTMON_8, ALTMON_9, ALTMON_10, ALTMON_11, ALTMON_12,
	_NL_WALTMON_1, _NL_WALTMON_2, _NL_WALTMON_3, _NL_WALTMON_4,
	_NL_WALTMON_5, _NL_WALTMON_6, _NL_WALTMON_7, _NL_WALTMON_8,
	_NL_WALTMON_9, _NL_WALTMON_10, _NL_WALTMON_11, _NL_WALTMON_12.
	* locale/programs/ld-time.c: Alternative month names support
	added, they are a copy of mon if not specified explicitly.
	* locale/programs/locfile-kw.gperf: alt_mon defined.
	* locale/programs/locfile-token.h: tok_alt_mon defined.
	* localedata/tst-langinfo.c: Add tests for the new constants
	ALTMON_1 .. ALTMON_12.
	* time/Makefile (LOCALES): Add pl_PL.UTF-8 for tests.
	* time/strftime_l.c: %OB format for alternative month names
	added.
	* time/strptime_l.c: Alternative month names also recognized.
	* time/tst-strptime.c: Add tests to parse different forms of
	month names including the new %OB format specifier.

Carlos, what do you think about splitting this into:

	* locale/langinfo.h: New public symbols _NL_WALTMON_1,
	_NL_WALTMON_2, _NL_WALTMON_3, _NL_WALTMON_4, _NL_WALTMON_5,
	_NL_WALTMON_6, _NL_WALTMON_7, _NL_WALTMON_8, _NL_WALTMON_9,
	_NL_WALTMON_10, _NL_WALTMON_11, _NL_WALTMON_12.
	[__USE_GNU]: New public symbols ALTMON_1, ALTMON_2, ALTMON_3,
	ALTMON_4, ALTMON_5, ALTMON_6, ALTMON_7, ALTMON_8, ALTMON_9,
	ALTMON_10, ALTMON_11, ALTMON_12.

or even:

	* locale/langinfo.h: New public symbols __ALTMON_1,
	__ALTMON_2, __ALTMON_3, __ALTMON_4, __ALTMON_5, __ALTMON_6,
	__ALTMON_7, __ALTMON_8, __ALTMON_9, __ALTMON_10, __ALTMON_11,

	_NL_WALTMON_8, _NL_WALTMON_9, _NL_WALTMON_10, _NL_WALTMON_11,

I think Dmitry has given a good suggestion here, and I would follow
what he recommends. The ChangeLog is a bit messy with complex macros
like this, and you have done a great job with it.

High level:

Overall the idea you have proposed makes perfect sense. I'm excited to see
someone pushing a new interface design like this to solve real language
problems with the interfaces. I look forward to the POSIX standardization.
My obvious worry remains that POSIX does not standardize %OB/%Ob, but all
we can do is lead by example and solve user problems. Thank you for this
work.

Design:

By the very definition of the %O* variants, if the locale does not 
provide ALTMON_* then it must revert back to the non-%O* variant e.g. %B. 
I see this implemented in the parser which is good.

I also see that strftime is relaxed in what it accepts and that is also
good and required.

One oddity I noticed in patch 3 is the missing ABALTMON_* definitions
for the _GNU_SOURCE case, is that on purpose and why? It's not needed,
but it seems like a missing useful feature that completes the API.

Implementation:

My only request here is additional tests that verify, for locales
that don't have ALTMON or ABALTMON specified, thus verifying the fallback
works. With that added I think you can commit this change squashed together
with the pl_PL and ru_RU changes and the test cases fixed up to pass.

Here we need examples of %OB for langauges that do *not* have genitive names
in order to test the conversion of %OB for locales that would have this
definition missing (tests that %OB does fall back to %B).

I guess you meant __USE_GNU because that's what my patch uses.  So does
/usr/include/langinfo.h everywhere.  Should I use _GNU_SOURCE instead?

OK, I'm adding en_US.ISO-8859-1 for %B, de_DE.ISO-8859-1 for %b
(those locales look weird but they are already used in this file so
we don't need to add them), fr_FR.UTF-8 for %OB, and then I'll also
add es_ES.UTF-8 for %Ob in another patch which adds %Ob.

Your use of __USE_GNU is *correct*, that is the internal macro that glibc
uses when enabling GNU extensions.

The user or developer will not use __USE_GNU, instead they will define
_GNU_SOURCE (feature test macro), and that will under the hood define
__USE_GNU (see include/features.h).

Again, you don't need to change anything here, my "OK." indicates that
I saw everything correct. My subsequent comment is designed to educate
those reading the review and provide insight into what I was looking
for in my review.

Initially I had an idea to add the alternative month names but
initialize them all to empty strings ("") and rely on the mechanism
which falls back to the regular month names if the alternative ones
are empty.  Then this has been changed to initialize them just "January",
"February", etc.  How to name those month names?  Regular?  Nominative?
Basic?  Non-alternative?

This is OK but shouldn't we mention that alt_mon content is copied
from mon (and walt_mon from wmon) if not specified explicitly in the
locale data file?

I'm confused.  Actually alt_month_name has been added globally
in the #ifdef _LIBC section so I think this makes sense:

* time/strptime_l.c [_LIBC] (alt_month_name): New macro.

But I don't understand what do you mean by "(__strptime_internal)
[_LIBC]: Add ... (whatever is being added)."  It's "Handle %OB format"
what has been added.  And it's not really conditional [_LIBC]; the
difference is that if _LIBC is not defined then %OB format is accepted
but alternative month names are not checked (because alt_month_name does
not exist).  Is this a copy-paste typo?  What else do I miss?

Does the question mark mean that you are not sure?  Well, this comment
has been provided by Zack Weinberg who is a native English speaker.
We both are not native speakers so I'd rather trust Zack here.  So far
I don't change this comment unless other native speakers tell me to change.

Whatever you like, I'd just use "month names":

* locale/C-time.c (_nl_C_LC_TIME): Update nstrings.  Add alternative month
names defined to the same string values as month names.

If it's not conditional, than [_LIBC] is not needed.

I read this as "month is a part of a part of a complete date" which
is too complex unless your intention is to highlight that month name
is a subpart.

I did not mean this sentence to be a definitive native-speaker
pronouncement on How To Say This In English.  That _anyone_ finds it
confusing is enough reason to revise it.

But I'm having trouble revising it - I'm sure it should begin with

/* Long month names, in the grammatical form used when ...

but I don't know what to put after "when" anymore.  Perhaps the
problem is that I don't speak any language that needs this feature!
How would *you* describe it?

/* Long month names, in the grammatical form used when the month is a part
   of a complete date. */

The closes analogy in English I could think of is "of January" in phrase
"11th of January".

Sounds good to me!  And I think I understand where the confusion came
from now.  In "the month forms part", "forms" was meant to be read as
a _verb_, with essentially the same meaning as your "the month is a
part", but because of the earlier "grammatical form", it sounded like
it was another use of the _noun_ "form", in the plural.  I shall
remember that for future wordsmithing.

While iterating over your remarks I have found more symbols which
have not been mentioned so I will review and add them.  For example,
the same changes should be applied to the next patch which adds
abbreviated alternative month names.  But now as I got the pattern
of the ChangeLog style then I'll just follow it rather than copy
and paste your comments blindly.

Zack has already explained this and AFAIUC he kinda agrees with you.

[PATCH v11 3/5] Abbreviated alternative month names (%Ob) also added (bug 10871).

[Rafal Luzynski]

All the previous changes also repeated to support abbreviated
alternative month names.  In most languages which have declension and
need nominative/genitive month names the abbreviated forms for both
cases are the same.  An example where they do differ is May in Russian:
this name is too short to be abbreviated so even the abbreviated form
features the declension suffixes.

	[BZ #10871]
	* locale/C-time.c: Add abbreviated alternative month names, define
	them as the same as abbreviated month names explicitly.
	* locale/categories.def: ab_alt_mon and wide-ab_alt_mon added.
	* locale/langinfo.h: New public symbols _NL_ABALTMON_1,
	_NL_ABALTMON_2, _NL_ABALTMON_3, _NL_ABALTMON_4, _NL_ABALTMON_5,
	_NL_ABALTMON_6, _NL_ABALTMON_7, _NL_ABALTMON_8, _NL_ABALTMON_9,
	_NL_ABALTMON_10, _NL_ABALTMON_11, _NL_ABALTMON_12,
	_NL_WABALTMON_1, _NL_WABALTMON_2, _NL_WABALTMON_3, _NL_WABALTMON_4,
	_NL_WABALTMON_5, _NL_WABALTMON_6, _NL_WABALTMON_7, _NL_WABALTMON_8,
	_NL_WABALTMON_9, _NL_WABALTMON_10, _NL_WABALTMON_11, _NL_WABALTMON_12.
	* locale/programs/ld-time.c: Abbreviated alternative month names
	support added, they are a copy of abmon if not provided
	explicitly.
	* locale/programs/locfile-kw.gperf: ab_alt_mon defined.
	* locale/programs/locfile-token.h: tok_ab_alt_mon defined.
	* time/Makefile (LOCALES): Add ru_RU.UTF-8 for tests.
	* time/strftime_l.c: %Ob (%Oh) format for abbreviated
	alternative month names added.
	* time/strptime_l.c: Abbreviated alternative month names also
	recognized.
	* time/tst-strptime.c: Add more tests to parse different forms of
	month names including the new %Ob format specifier.

Short answer: the idea to define ABALTMON_* did not yet exist when
I was implementing this.  And even now I'm not sure this is the right
moment to add this already.

Long answer: the reason behind defining ALTMON_ via #ifdef __USE_GNU is
that this standard already exists somewhere (in BSD and as accepted but
not yet published future change in POSIX) but while it is not yet officially
specified by POSIX we treat it as a GNU extension (hence #ifdef __USE_GNU)
while __ALTMON_* symbols are defined unconditionally.  But the idea of
introducing abbreviated alternative month names to glibc is originally
mine (although it already exists in other libraries, like ICU) and I did
not think it would be standardized.  So I have defined them as _NL_ABALTMON_*
(as a forever private GNU extension).  However, the idea has been filed
as a POSIX update proposal only on October 27, 2017. [1] I don't think
it will be accepted and published soon.

So, do you guys want me to use a different naming pattern already?

I am going to publish another set of patches, mostly due to the changes

Please keep the code as-is. Thank you for explaining the situation, it clarifies
the point. The code is OK to go in as-is.

Yes, it applies also to the new patches, as long as no substantive changes
are made to the code. I don't count the ChangeLog as being substantive.

+* Support for two grammatical forms of month name has been added.
+  In a call to strftime, the "%B" and "%b" format specifiers will now
+  produce the grammatical form required when the month is used as part
+  of a complete date.  New "%OB" and "%Ob" specifiers produce the form

+  are all valid and will all accept any known form of month
+  name---standalone or complete, abbreviated or full.  In a call to

Re: [PATCH] pl_PL: Add alternative month names (bug 10871).

[Rafal Luzynski]

Now I think that maybe this patch should also change these lines
from the first patch:

+  /* TODO: Use the genitive case here as soon as it is added to localedata.  */
+  { "pl_PL.UTF-8", "23 listopad 2017", "%d %B %Y", 4, 326, 10, 23 },

into something like:

-  /* TODO: Use the genitive case here as soon as it is added to localedata.  */
-  { "pl_PL.UTF-8", "23 listopad 2017", "%d %B %Y", 4, 326, 10, 23 },
+  { "pl_PL.UTF-8", "23 listopada 2017", "%d %B %Y", 4, 326, 10, 23 },

I don't mean that the first patch is wrong but it contains a placeholder
for a test which should be added as soon as pl_PL localedata contains
both mon and alt_mon arrays.

Regards,

Rafal
