Modelica library for gettext evaluation
This is a Modelica library only created for gettext evaluation as proof of concept for the Modelica specification issue #302.
The POT file TranslationTest.pot (Portable Object Template) was created by the command
xgettext --language=EmacsLisp --sort-output --extract-all --from-code=UTF-8 --output=TranslationTest.pot TranslationTest.mo
The TranslationTest.pot file serves as translation template and contains the extracted original strings as msgid together with an empty string msgstr, for example
#: TranslationTest.mo:34
msgid "Contact info"
msgstr ""
Afterwards, the required msgctxt field was manually added for each recognized string, for example
#: TranslationTest.mo:34
msgctxt "TranslationTest.UsersGuide.Contact"
msgid "Contact info"
msgstr ""
Certainly, the string extraction based on the EmacsLisp language can only be considered as proof of concept, since there is no Modelica language available in xgettext. It is recommended to create the POT file directly from the Modelica tool, like e.g., demonstrated by Wolfram SystemModeler.
The PO file TranslationTest.de.po (Portable Object) was created in Poedit, but could also be created using the gettext tools by command
msginit --input=TranslationTest.pot --locale=de_DE --output=TranslationTest.de.po
These PO files can be created for any supported language. It is highly recommended that these PO files are stored as UTF-8 and that this is respected by charset=UTF-8 in the meta information of the file.
The actual translation work was done in Poedit again.
If the original Modelica file TranslationTest.mo changes, the translation process needs to be iterated again, by creating an updated TranslationTest.pot and merging it with the already available translation files by command
msgmerge --update TranslationTest.de.po TranslationTest.pot
The freely available C++ library spirit-po was used as PO file reader in SimulationX. It supports UTF-8 encoded files only and is available under the BSL 1.0, a permissive OSI approved license.
