lrelease-qt4 (1)

NAME

lrelease - generate Qt message files from Qt Linguist translation files

SYNOPSIS

lrelease [ options ] project-file
lrelease [ options ] ts-files [ -qm qm-file ]

DESCRIPTION

This page documents the Qt Linguist Release tool for the Qt GUI toolkit. Lrelease reads a qmake/tmake project file (.pro file) and converts the translation files (.ts files) specified in it into Qt message files (.qm files) used by the application to translate.

The .qm file format is a compact binary format that provides extremely fast lookups for translations and that is used by Qt.

OPTIONS

-help

Display the usage and exit.

-compress

Compress the .qm files.

-nounfinished

Do not include unfinished translations.

-removeidentical

If the translated text is the same as the source text, do not include the message.

-silent

Do not explain what is being done.

-version

Display the version of lrelease and exit.

USAGE

Here is an example .pro file that can be given to lrelease:

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

When running lrelease on this project file, the Qt message files gnomovision_dk.qm, gnomovision_fi.qm, gnomovision_no.qm and gnomovision_se.qm will be generated from gnomovision_dk.ts, gnomovision_fi.ts, gnomovision_no.ts and gnomovision_se.ts, respectively.

Lrelease can also be invoked with a list of .ts files to convert:

lrelease gnomovision_*.ts
