How to bootstrap a new pair

How to use apertium-init to bootstrap a new language pair (optionally with new monolingual data packages as well).

Prerequisites

You need to get this installed first:

• apertium/lttoolbox/hfst, see Installation, in particular the prerequisites parts. (You most likely don't need to go all the way to "minimal installation from svn", since you should get this stuff from Tino's repositories. If you're on Windows, get the virtualbox)
• apertium-init – put this script in your working directory where you will be downloading language data

With two existing monolingual packages

Do the two languagues you're making a pair of already have monolingual modules in https://svn.code.sf.net/p/apertium/svn/languages/ (or perhaps https://svn.code.sf.net/p/apertium/svn/incubator )?

Then follow this part, replacing LANG1 and LANG2 for the ISO 639-3 codes of your languages:

First compile the monolingual packages:

svn co https://svn.code.sf.net/p/apertium/svn/languages/apertium-LANG1
cd apertium-LANG1
./autogen.sh
make -j
cd ..
svn co https://svn.code.sf.net/p/apertium/svn/languages/apertium-LANG2
cd apertium-LANG2
./autogen.sh
make -j
cd ..

Then generate the pair:

python3 apertium-init.py LANG1-LANG2

Then compile the pair:

./autogen.sh --with-lang1=../apertium-LANG1 --with-lang2=../apertium-LANG2
make -j

And test:

echo house | apertium -d . LANG1-LANG2
echo Haus | apertium -d . LANG2-LANG1

Now you can add words to apertium-LANG1-LANG2.LANG1-LANG2.dix, then test again:

make -j
echo house | apertium -d . LANG1-LANG2
echo Haus | apertium -d . LANG2-LANG1

If you had to add words to the monolingual dictionaries, you will have to type "make" in those directories first. Alternatively, there is a shortcut from the pair directory: "make langs" should make the monolingual dictionaries even if you're in the pair directory.

With one existing monolingual package

Does just one of the two languagues you're making a pair of already have a monolingual module in https://svn.code.sf.net/p/apertium/svn/languages/ (or perhaps https://svn.code.sf.net/p/apertium/svn/incubator )?

Then follow this part, replacing LANG1 and LANG2 for the ISO 639-3 codes of your languages; here we assume LANG1 needs to be made from scratch.

First make a new monolingual package:

python3 apertium-init.py LANG1
cd apertium-LANG1
./autogen.sh
make -j
cd ..

Then get and compile the existing monolingual package:

svn co https://svn.code.sf.net/p/apertium/svn/languages/apertium-LANG2
cd apertium-LANG2
./autogen.sh
make -j
cd ..

Then generate the pair:

python3 apertium-init.py LANG1-LANG2

Then compile the pair:

./autogen.sh --with-lang1=../apertium-LANG1 --with-lang2=../apertium-LANG2
make -j

And test:

echo house | apertium -d . LANG1-LANG2
echo Haus | apertium -d . LANG2-LANG1

Now you can add words to apertium-LANG1-LANG2.LANG1-LANG2.dix, then test again:

make -j
echo house | apertium -d . LANG1-LANG2
echo Haus | apertium -d . LANG2-LANG1

If you had to add words to the monolingual dictionaries, you will have to type "make" in those directories first. Alternatively, there is a shortcut from the pair directory: "make langs" should make the monolingual dictionaries even if you're in the pair directory.

With no existing monolingual packages

Do none of the two languagues you're making a pair of already have monolingual modules in https://svn.code.sf.net/p/apertium/svn/languages/ or https://svn.code.sf.net/p/apertium/svn/incubator ?

Then follow this part, replacing LANG1 and LANG2 for the ISO 639-3 codes of your languages:

First make and compile the new monolingual packages:

python3 apertium-init.py LANG1
cd apertium-LANG1
./autogen.sh
make -j
cd ..

python3 apertium-init.py LANG2
cd apertium-LANG2
./autogen.sh
make -j
cd ..

Then generate the pair:

python3 apertium-init.py LANG1-LANG2

Then compile the pair:

./autogen.sh --with-lang1=../apertium-LANG1 --with-lang2=../apertium-LANG2
make -j

And test:

echo house | apertium -d . LANG1-LANG2
echo Haus | apertium -d . LANG2-LANG1

Now you can add words to apertium-LANG1-LANG2.LANG1-LANG2.dix, then test again:

make -j
echo house | apertium -d . LANG1-LANG2
echo Haus | apertium -d . LANG2-LANG1

If you had to add words to the monolingual dictionaries, you will have to type "make" in those directories first. Alternatively, there is a shortcut from the pair directory: "make langs" should make the monolingual dictionaries even if you're in the pair directory.
