I am so happy that this is really comming true: A zero-install* locally
running Apertium translator :-)
Let me add that Mikel has also upgraded Apertium-viewer to use the new
stuff (its not zero-install yet, but that'll probably come), giving
teachers, students and curious people a great and easy opportunity to peek
at and play with the inner workings of rule base maching translation,
without using any time/energy on installation or setup.
You'll just point the students to a web page, a Java program will open, and
they can edit input (or or any stage of the translation), and follow how
translation is done, with zero setup or installation effort.
* yes yes I know the limitations:
- you need a Java runtime installed, and
- only the pairs using core Apertium is zero-install, you'd still need to
install HFST, constraint grammar and other external stuff.

If its 'just' 1MB I think we should just make it easy for people and let
them forget about installing the Android SDK: Just add
it to the libs/ folder of lttoolbox-java.

I'd like everyone to take a look at the language pair packs at:
https://apertium.svn.sourceforge.net/svnroot/apertium/branches/gsoc2012/artetxem/packages/jars/
The JAR files are actually ZIP files. If you take a look inside for
example ca-es,es-ca.jar, it contains the language pair, plus some extra
stuff:
$ unzip -l ca-es,es-ca.jar
Archive: ca-es,es-ca.jar

The first is the language pair as it would be installed. The last 2 entries
are the Android specific and the lttoolbox-java runtime specific stuff.
This could be deleted and the pair would *still* work from a C++ Apertium
installation.
The original file size is 2629328 bytes. If we delete the last 2 entries
the file size is 2339996 bytes.
That means that embedding the part that makes it runnable as a standalone
program (lttoolbox-java) AND Android classes only makes the total file size
12% bigger (each one is about 6% of the file size).
Further, the extra 'java bloat' can very easily be deleted by deleting the
2 entries (classes.dex and the org/ directory).
Therefore I think we should consider if we can live with 6-12% 'java bloat'
and if this new, easy format could be an easier and more flexible
alternative for distribution and installation of language pairs for end
users than downloading sourceforge packages ?
Yours,
Jacob
