Become a language pair developer for Apertium
This is a Step-by-step guide on how to use a development version of Apertium to make a change in a language pair. These instructions assume that you are using Ubuntu or Debian; if not then please see Installation for installation on other OS's such as Mac OS X or Windows.
Step 1: Install the Prerequisites
A development version of Apertium and the language pair you want to change has to be installed on your computer in order to change the language pair.
Then, use this command to install the prerequisites:
$ sudo apt-get install subversion build-essential g++ pkg-config gawk libxml2 \ > libxml2-dev libxml2-utils xsltproc flex automake autoconf libtool libpcre3-dev
The Terminal will then ask you for your password to begin. Note: Keep track of how you type your password in your head. The Terminal will not display characters related to your password.
After you have entered your password, press the "Enter" key and wait for your computer to download and install the packages.
Step 2: Get Apertium, lttoolbox, and Your Language Pair(s)
Using the same Terminal, you can download the entire language pairs tree from SVN using the command:
$ svn co https://apertium.svn.sourceforge.net/svnroot/apertium
Keep in mind that the full tree is over 4GB. If you have a slow connection or a limited data transfer amount, this is not recommended. However, if you want to focus on a small number of language pairs you can easily download and add language pairs with a command such as:
$ svn co http://apertium.svn.sourceforge.net/svnroot/apertium/trunk/lttoolbox $ svn co http://apertium.svn.sourceforge.net/svnroot/apertium/trunk/apertium $ svn co https://apertium.svn.sourceforge.net/svnroot/apertium/trunk/<modulename>
These commands download Apertium, lttoolbox, and the language pair that you want to use.
For example, if you wanted to get Apertium, lttoolbox, and the Spanish/English pair you could enter:
$ svn co http://apertium.svn.sourceforge.net/svnroot/apertium/trunk/lttoolbox $ svn co http://apertium.svn.sourceforge.net/svnroot/apertium/trunk/apertium $ svn co https://apertium.svn.sourceforge.net/svnroot/apertium/trunk/apertium-en-es
