This repository contains a number of text pre- and post-processing utilities written in the context of the Portage Statistical Machine Translation project. Since they are frequently useful outside that context, we have separated them into this repository that is designed to be trivial to install.
Clone this repo to the location of your choice and add this line to your .profile or .bashrc:
source /path/to/PortageTextProcessing/SETUP.bash
PortageTextProcessing requires:
- Perl >= 5.14, as
perlon your PATH, with the packages listed in cpanfile; - any version of Python 3, as
python3on your PATH, with the packages listed in requirements.txt; /bin/bash,/bin/sh,/usr/bin/env;xmllint(comes with libxml2) andxml_grep(comes with Perl's XML::Twig).
First, check if you already have these dependencies, since they are very common:
go to tests/check-installation/ and run ./run-test.sh. This test suite will
flag any missing dependencies.
Install missing dependencies with the package manager of your choice, ideally the OS's own distro manager, like apt, yum, or brew.
CentOS 7 packages:
yum install perl-XML-Twig perl-XML-XPath perl-XML-Writer libxml2 python3
Ubuntu 20.04 packages:
apt-get install libxml-twig-perl libxml-xpath-perl libxml-writer-perl
apt-get install libxml2-utils xml-twig-tools python3
For the Python 3 dependencies, with any OS:
pip3 install -r requirements.txt
For more extensive testing, go to tests/ and run ./run-all-tests.sh. Go into any
directory showing errors and examine _log.run-test to see what went wrong, or run
./run-test.sh interactively.
Some test suites are parallelized to run faster. If you have difficulty figuring out
which command caused the error, you can also run make -B interactively in any test
suite instead of ./run-test.sh, to run all its test cases sequentially and stop at the
first error.
If you have installed PortageClusterUtils,
you can also run all the test suites in parallel with ./run-all-tests.sh -j 12.
Each script accepts the -h option to output its documentation to your terminal.

If you want to contribute scripts to this repo, please:
- Make sure they require no compilation or installation (beyond sourcing
SETUP.bash). - Add unit tests for your scripts under
tests/. - Keep them relevant, which means pretty much anything related to text processing goes.
