The po.vim syntax file and the corresponding ftplugin file make Vim an efficient translation tool, with the pros and cons of showing the “gory details” of the file format. While the ftplugin still lives in the Vim.org scripts repository, the syntax highlight file is already distributed with Vim itself. In the last years I made Vim spell check only translated text and improved the highlight and spell check of XML tags, but now I don’t have the time or interest in further development. If anyone wants to add a feature or fix a bug in the syntax file, please send a patch to bram at moolenaar net. Thanks!
