==Requiring a monolingual package as a dependency of a pair==
Say you want apertium-[http://www.ethnologue.com/language/fie fie]-[http://www.ethnologue.com/language/bar bar] to depend on some monolingual data from the apertium-bar package, e.g. <code>apertium-bar/bar.rlx</code> and maybe other such files.

This requires a recent version of apertium (-r51152 or later), and that you've exported <code>PKG_CONFIG_PATH</code> as described at [[Minimal_installation_from_SVN]].

Assuming apertium-bar is set up correctly (see next section), you can put the following line into the <code>configure.ac</code> of apertium-fie-bar:
<pre>
AP_CHECK_LING([2], [apertium-bar])
</pre>

and in the <code>Makefile.am</code>, you can write rules like this:
<pre>
bar-fie.rlx.bin: $(AP_SRC2)/bar.rlx
cg-comp $< $@

bar-tat.automorf.bin: $(AP_LIB2)/bar.automorf.bin
cp $< $@
</pre>

Similarly for apertium-fie (with <code>AP_CHECK_LING([1], [apertium-fie])</code>). By convention, a language pair called apertium-fie-bar should use the number 1 for fie and 2 for bar (though variants like 1b are possible too). Also by convention, AP_SRC should point to source files and AP_LIB to compiled binaries (this is the responsibility of the monolingual package, e.g. apertium-bar).

Now if you've typed "make install" in apertium-bar before running autogen.sh in apertium-fie-bar, apertium-fie-bar will use the bar.rlx and bar.automorf.bin which are installed by apertium-bar.


If you often make a lot of changes to apertium-bar and want to avoid having to "make install" for each and every change, you can do this in apertium-fie-bar:
<pre>
./autogen.sh --with-lang2=/path/to/apertium-bar
</pre>
Now each time you make, the "AP_SRC2" and "AP_LIB2" variables will both point to /path/to/apertium-bar instead of the "make install"-ed files. You can set it back to default by just running plain <code>autogen.sh</code> (or <code>./configure</code>) again.


See [[Installation_troubleshooting#AP_CHECK_LING_not_found_when_running_configure_or_autogen.sh]] if you run into errors about AP_CHECK_LING.

==== Build the monolingual dependencies when you type 'make' in the language pair ====
Add
<pre>
SUBDIRS=$(AP_SUBDIRS)
</pre>
to Makefile.am in the language pair, and specify --with-lang (<code>./autogen.sh --with-lang2=/path/to/apertium-bar</code> etc.).

Now when you type 'make' in the language pair, it'll first go into apertium-bar and do a make there, then continue with make in apertium-fie-bar.

====Making a monolingual package dependable for pairs====
In apertium-bar, there should be a file <code>apertium-bar.pc.in</code>. This has to have the following lines:
<pre>
dir=@libdir@/apertium/apertium-bar
srcdir=@datarootdir@/apertium/apertium-bar
</pre>
These should correspond to where the binaries and source files respectively are installed by the <code>Makefile.am</code> in the monolingual package (typically the makefile names these directories <code>apertium_bardir</code> and <code>apertium_bar_srcdir</code>).

The <code>configure.ac</code> should have a line saying something like <code>AC_OUTPUT([Makefile apertium-bar.pc])</code>. See https://svn.code.sf.net/p/apertium/svn/languages/apertium-nob for a working example.

Compiled / binary files should be listed in TARGETS_COMMON as usual, while any source files can be installed using install-data-local, e.g.:

<pre>
apertium_bar_srcdir=$(prefix)/share/apertium/$(BASENAME)/
install-data-local:
test -d $(DESTDIR)$(apertium_bar_srcdir) || mkdir -p $(DESTDIR)$(apertium_bar_srcdir)
$(INSTALL_DATA) $(BASENAME).$(LANG1).dix $(DESTDIR)$(apertium_bar_srcdir)
</pre>

Now if the apertium-fie-bar pair depends on apertium-bar as its lang2, it can refer to binaries (apertium-bar's TARGETS_COMMON) using $(AP_LIB2) and source files using $(AP_SRC2), e.g. <code>$(AP_SRC2)/apertium-$(LANG2).$(LANG2).dix</code> for the dix file in the install-data-local example above.

/languages/ is a module of the SVN where monolingual language data lives. Monolingual language data in Apertium is slowly being moved to this new repository scheme. (Originally, all monolingual language data was found in language pairs, meaning that there was a lot of duplication.) If you feel something is missing, please feel free to contact us.

New monolingual packages should be developed in incubator until they're minimally useful, at which point they can go in /languages/. There is no fixed criterion for what constitutes a minimally-useful language package; generally, however, a language package should have over 60% coverage on a variety of corpora and should probably have at least 2500 stems to be considered minimally useful.

The /languages/ module can be found in svn at https://svn.code.sf.net/p/apertium/svn/languages .

Language family pages

Language family pages exist to show the overall progress of monolingual language modules for regions and language families of interest. Currently the following pages are (or should soon be) available on this wiki (family names in bold use the format described below):

The language family pages should represent the following data in a standardised format:

  • The languages of that group with apertium data (whether in languages, incubator, part of a pair in trunk, etc.)
  • 2- and 3-letter ISO codes for each language
  • The formalism the module is written in
  • Links to the pages for each language on the apertium wiki
  • The location in the apertium repository (whether in languages, incubator, part of a pair in trunk, etc.)
  • Development status, which should be one of the following:
    • production - for language modules used in a released pair, usually over 90% coverage and/or over 10,000 stems
    • working - for language modules with near-production-quality performance, usually over 80% coverage and/or over 8'000 stems
    • development - for language modules under development, usually over 60% coverage and/or over 1'000 stems
    • prototype - for language modules that have not received heavy development, usually less than 60% coverage or under 1'000 stems

Here are status guidelines summarised in a table:

status description stems coverage bidix table
prototype language module that has not received heavy development <1,000 <60%
development language module under development ≥1,000 ≥60%
working language module with near-production-quality performance ≥8,000 ≥80%
production language module used in a released pair ≥10,000 ≥90%


Additionally, the following data is put on apertium-xxx/stats pages, and is included on the language family page and other places as relevant:

  • The number of stems (and paradigms if relevant) in that language module
  • The coverage of the transducer on a variety of corpora

There should also be a table of language pairs available with these languages, with number of stems from apertium-xxx-yyy/stats pages on the wiki. Guidelines for font semantics for the pairs follow:

  • production / trunk = bold
  • working / staging = bold+italics
  • development / nursery = normal
  • prototype / incubator = italics

Optional information includes samples of a single text in these languages and UNESCO-provided vulnerability data.
