.. _pot2po: pot2po ****** Convert a Gettext PO Template file to a PO file and merge in existing translations if they are present. A translation memory (compendium) can also be used for fuzzy matching. This corresponds to a large extent with the program "msgmerge" from the gettext package. .. _pot2po#usage: Usage ===== :: pot2po [options] <pot> <po> Where: +--------+---------------------------------------------------------+ | <pot> | is a PO Template (POT) file or directory of POT files | +--------+---------------------------------------------------------+ | <po> | is a PO file or a directory of PO files | +--------+---------------------------------------------------------+ Options: --version show program's version number and exit -h, --help show this help message and exit --manpage output a manpage based on the help --progress=PROGRESS show progress as: :doc:`dots, none, bar, names, verbose <option_progress>` --errorlevel=ERRORLEVEL show errorlevel as: :doc:`none, message, exception, traceback <option_errorlevel>` -iINPUT, --input=INPUT read from INPUT in pot format -xEXCLUDE, --exclude=EXCLUDE exclude names matching EXCLUDE from input paths -oOUTPUT, --output=OUTPUT write to OUTPUT in po, pot formats -tTEMPLATE, --template=TEMPLATE read from TEMPLATE in po, pot formats (old translations) --psyco=MODE use psyco to speed up the operation, modes: :doc:`none, full, profile <option_psyco>` -P, --pot output PO Templates (.pot) rather than PO files (.po) --tm=TM The file to use as translation memory when fuzzy matching -sMIN_SIMILARITY, --similarity=MIN_SIMILARITY The minimum similarity for inclusion (default: 75%) --nofuzzymatching Disable all fuzzy matching .. _pot2po#examples: Examples ======== :: pot2po -t zu-1.0.1 pot-2.0.2 zu-2.0.2 Here we are initialising the PO files in *zu-2.0.2* based on the POT files in *pot-2.0.2*. We are using the old translations in *zu-1.0.1* as templates so that we can reuse our existing translations in the new files. If the POT files have undergone major reshuffling then you may want to use :doc:`pomigrate2` which can now use pot2po as its merging backend. pomigrate2 will do its best to migrate your files to the correct locations before merging. It will also make make use of a compendium if requested.:: pot2po --tm=compendium.po --similarity=60 -t xh-old pot xh-new With this update we are using *compendium.po* as a translations memory (you can make use of other files such as TMX, etc). We will accept any match that scores above *60%*. .. _pot2po#merging: Merging ======= It helps to understand when and how pot2po will merge. The default is to follow msgmerge's behaviour but we add some extra features with fuzzy matching: * If everything matches we carry that across * We can resurrect obsolete messages for reuse * Messages no longer used are made obsolete * If we cannot find a match we will first look through the current and obsolete messages and then through any global translation memory * Fuzzy matching makes use of the :doc:`/commands/levenshtein_distance` algorithm to detect the best matches .. _pot2po#performance: Performance =========== Fuzzy matches are usually of good quality. Installation of the `python-Levenshtein <https://sourceforge.net/project/showfiles.php?group_id=91920&package_id=260161>`_ package will speed up fuzzy matching. Without this a Python based matcher is used which is considerably slower. Install psyco for additional speedup (it is used by most toolkit tools if it is installed.) .. _pot2po#bugs: Bugs ==== * :doc:`pomerge` and pot2po should probably become one.
