file data, I used imaginary abstract class StreamReader to do all

provided two classes for reading files: FileReader and
- StringReader (CachedFileReader is a combination of the two: it
- loads entire file contents into a string, and then works on that).
- See example below for usage. You can for instance use StringReader

-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.
+Bugs
- 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>.

Usage
Then, use that as a parameter to gettext_reader constructor:
$wohoo = new gettext_reader($streamer);
- If you want to disable pre-loading of entire message catalog in
- memory (if, for example, you have a multi-thousand message catalog
- which you'll use only occasionally), use "false" for second

From now on, you have all the benefits of gettext data at your
- disposal, so may run:
+ disposal, so may run:
print $wohoo->translate("This is a test");

xgettext -ktranslate -kngettext:1,2 file.php
what should create messages.po which contains two messages for
translation.

POT file and to update the translation using msgmerge.
-Interesting TODO:
+TODO:
- o Try to parse "plural-forms" header field, and to follow C syntax
- rules. This won't be easy.
+ o Improve speed to be even more comparable to the native gettext

-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 ;-).
