Bugs
|
||||
|
||||
Plural-forms field in MO header (translation for empty string,
|
||||
i.e. "") is treated according to PHP syntactic rules (it's
|
||||
eval()ed). Since these should actually follow C syntax, there are
|
||||
some problems.
|
||||
|
||||
For instance, I'm used to using this:
|
||||
Plural-Forms: nplurals=3; plural=n%10==1 && n%100!=11 ? 0 : \
|
||||
n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2;
|
||||
but it fails with PHP (it sets $plural=2 instead of 0 for $n==1).
|
||||
|
||||
The fix is usually simple, but I'm lazy to go into the details of
|
||||
PHP operator precedence, and maybe try to fix it. In here, I had
|
||||
to put everything after the first ':' in parenthesis:
|
||||
Plural-Forms: nplurals=3; plural=n%10==1 && n%100!=11 ? 0 : \
|
||||
(n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2);
|
||||
That works, and I'm satisfied.
|
||||
|
||||
Besides this one, there are probably a bunch of other bugs, since
|
||||
I hate PHP (did I mention it already? no? strange), and don't
|
||||
know it very well. So, feel free to fix any of those and report
|
||||
them back to me at <danilo@kvota.net>.

Interesting TODO:
|

TODO:
|
||||
|
||||
o Try to parse "plural-forms" header field, and to follow C syntax
|
||||
rules. This won't be easy.
|
||||
|
||||
Boring TODO:
|
||||
|
||||
o Learn PHP and fix bugs, slowness and other stuff resulting from
|
||||
my lack of knowledge (but *maybe*, it's not my knowledge that is
|
||||
bad, but PHP itself ;-).
|
||||
|
||||
(This is mostly done thanks to Nico Kaiser.)
|
||||
o Improve speed to be even more comparable to the native gettext
|
||||
implementation.
|
||||
|
||||
o Try to use hash tables in MO files: with pre-loading, would it
|
||||
be useful at all?
