lupdate interprets "\n" differently in C++ and QML translation comments

    XMLWordPrintable

Details

    Description

      lupdate behaves differently when encountering the escape sequence \n in translation comments in C++ or QML.

      For example, the QML

      foo.qml
      import QtQuick 2.6

Item {
    /*% "Test\ntext"
     */
    /*: Some translation comment\n
        with line break.
     */
    property string dummyText: qsTrId("myTextId")
}

      produces a message in the .ts file like this:

      <message id="myTextId">
    <source>Test\ntext</source>
    <extracomment>Some translation comment\n with line break.</extracomment>
    <translation type="unfinished"></translation>
</message>

      So the \n are not interpreted but taken literally.

      While the same translation comment in C++

      foo.cpp
      /*% "Test\ntext"
 */
/*: Some translation comment\n
    with line break.
 */
static QString myText = qtTrId("myTextId");

      produces a message like this:

      <message id="myTextId">
    <source>Test
text</source>
    <extracomment>Some translation comment
 with line break.</extracomment>
    <translation type="unfinished"></translation>
</message>

      So the \n are converted to line breaks.

      Steps to reproduce:

      • Run lupdate on the above given foo.qml or foo.cpp: 
        lupdate foo.qml -ts foo-qml.ts
lupdate foo.cpp -ts foo-cpp.ts

      Expected Behavior:

      Identical translation comments should produce the same message in the .ts files.
