The translation files are given to the translator who uses .B Qt Linguist to read the files and insert the translations. .PP The TS file format is a simple human-readable XML format that can be used with version control systems if required. .PP .SH OPTIONS .TP .I "-disable-heuristic {sametext|similartext|number}" Disable the named merge heuristic. Can be specified multiple times. .TP .I "-extensions [,...]" Process files with the given extensions only. The extension list must be separated with commas, not with whitespace. Default: 'ui,c,c++,cc,cpp,cxx,ch,h,h++,hh,hpp,hxx'. .TP .I "-help" Display the usage and exit. .TP .I "-locations {absolute|relative|none}" Specify/override how source code references are saved in TS files. Default is absolute. .TP .I "-no-obsolete" Drop all obsolete strings. .TP .I "-no-recursive" Do not recursively scan the following directories. .TP .I "-no-sort" Do not sort contexts in TS files. .TP .I "-pluralonly" Only include plural form messages. .TP .I "-pro " Name of a .pro file. Useful for files with .pro file syntax but different file suffix .TP .I "-recursive" Recursively scan the following directories. .TP .I "-silent" Do not explain what is being done. .TP .I "-source-language [_]" Specify/override the language of the source strings. Defaults to POSIX if not specified and the file does not name it yet. .TP .I "-target-language [_]" Specify/override the language of the translation. The target language is guessed from the file name if this option is not specified and the file contents name no language yet. .I "-version" Display the version of .B lupdate and exit. .SH USAGE Here is an example .pro file that can be given to .B lupdate: .PP .in +4 .nf HEADERS = funnydialog.h \\ wackywidget.h SOURCES = funnydialog.cpp \\ main.cpp \\ wackywidget.cpp FORMS = fancybox.ui TRANSLATIONS = gnomovision_dk.ts \\ gnomovision_fi.ts \\ gnomovision_no.ts \\ gnomovision_se.ts .fi .in -4 .PP When running .B lupdate on this project file, the translatable strings in all the files listed in the HEADERS, SOURCES and FORMS entries will be put in the translation files listed in the TRANSLATIONS entry. Previous translations will be reused as far as possible, and translated strings that have vanished from the source files are marked obsolete. .PP .B lupdate can also be invoked with a list of C++ source files, UI files and TS files: .PP .in +4 .nf lupdate *.cpp *.h *.ui -ts gnomovision_dk.ts .fi .in -4 .SH "SEE ALSO" .BR lrelease (1) and .BR http://qt.nokia.com/doc/i18n.html
