GettextPO¶ ↑

This is a Ruby library for the GNU gettext PO files. This is a C binding of the libgettextpo library, which is provided by the GNU gettext package. It is designed to promote Ruby’s idiomatic coding style while avoiding memory leaks.

Installation¶ ↑

Prerequisites: libgettextpo library. On Linux and similar systems, you should be able to install it as a distribution package on most platforms. For example, on Ubuntu it was as follows (2026-03-07T15:48:13+09:00):

apt search libgettextpo
# Sorting... Done
# Full Text Search... Done
# libgettextpo-dev/noble 0.21-14ubuntu2 amd64 <----- This one!
#   process PO files - static libraries and headers
#
# libgettextpo0/noble 0.21-14ubuntu2 amd64
#   process PO files - shared library

Install the gem and add to the application’s Gemfile by executing:

bundle add gettextpo

If Bundler is not being used to manage dependencies, install the gem by executing:

gem install gettextpo

Usage¶ ↑

Say we have a PO file like:

msgid "msgid1"
msgstr "msgstr1"

at po_path, then,

require "gettextpo"

GettextPO::File.read(po_path).message_iterator.each do |message|
  pp({ source: message.msgid, translation: message.msgstr })
  #=> {source: "msgid1", translation: "msgstr1"}
end

Please refer to the API documentation and test cases for details.

Development¶ ↑

./bin/debug to debug when segmentation fault.

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
