Localization through Internationalization (or l10n via i18n)
I just now cleaned up the last bit of code that required me to maintain
multiple copies of mod_blog [1], depending upon the user. The problem
revolved around the month of December [2] and how I feel about it.
Last year around this time I added the following to mod_blog:
> if (day.tm_mon == 11)
> {
> char dayname[BUFSIZ];
>
> strftime(dayname,BUFSIZ,"%A",&day);
> fprintf(
> fpout,
> "%s, Debtember %02d, %d",
> dayname,
> day.tm_mday,
> day.tm_year + 1900
> );
> return;
> }

If you look closely, you'll notice that I render a date like “Wednesday,
December 04, 2002” as “Wednesday, **Debtember** 04, 2002” as a personal
protest to the extreme messages of mass consumerism consumption we are
bombarded with during that month.
Although the other user (Hi, Mark [3]!) didn't like that feature, so it was a
simple matter of making that code conditional and I did it at compile time,
not run time (as a matter of personal preference on my part) but in
retrospect, it would have been easier to make it a runtime option, but one
that I was relunctant to do since it was so specific.
But over the year it meant I had to compile the program twice—once for me,
once for Mark (there was another aspect that was different between my version
and Mark's that was amplified when Gregory [4] decided to use mod_blog but
that aspect as since been fixed) which gets to be a pain. And yet I still
resisted making this a runtime decision.
I could have made this a general feature, the ability to specify alternative
names for months, but then why stop there? Why not the days of the week [5]?
But what galls me is that adding such features mean I have to forego using
strftime() to format the dates (well, not that there aren't problems with the
routines in time.h already) and duplicate pretty much what I'm already using.
It was today when I figured out a solution. It may not be the best solution
but it does mean I can rip out the above code, meaning I only have to compile
once, and I can still use strftime() to format the date, and I can have
Debtember, and Mark (and Gregory) can have December.
Locales.
Like I said, it may not be the best of solutions, but it does work.
ANSI-C has the concept of a “locale” which specifies such details of output
as the currency symbol, decimal point, number group separators as well as the
names of the weekdays and months. Usually this defaults to the C or POSIX
locale (which is another word for US (United States) hegemony on the
computing world) but it can be changed with setlocale()—all that remains is
to figure out how to create a new locale for my own use.
There isn't much information about doing this, but I was able to munge my way
through. Under Linux (at least Gentoo [6] and RedHat [7] from what I can
tell), it meant creating a file under /usr/share/i18n/locales (I created one
called en_SPC for ENglish, SPC variant with “Debtember”) and then doing
localedef -i en_SPC en_SPC to actually add it to the system.
So I did have to add an option to the configuration file, but now it
specifies the locale to use, which, generally speaking, is a better hack than
what I had before.
