Overview

The qmljsreformatter tool allows to automatically format a QML file via a command-line interface. It is based on a functionality embedded in the Qt Creator IDE.

This project supports two versions of qmljsreformatter:

  • The original version whose the source code comes from Qt Creator.
  • The Orange version which is a modified version of the Qt Creator source code, which:
    • allows to split (or not) the long lines.
    • adds automatically semicolons (;) at the end of the JavaScript statements.

How to build qmljsreformatter as a standalone binary

Build Qt 5.12 sources:

git clone git://code.qt.io/qt/qt5.git
cd qt5
git checkout v5.12.8
./init-repository
./configure -prefix {SOMEWHERE}/Qt5.12.8.static -opensource -static -skip wayland -no-egl -nomake examples -nomake tests
make -j 4 # (or more jobs if possible)
make install

Note: Qt 5.12.8 is the last tested version to compile qmljsreformatter but a more recent version should work too!

Build qmljsreformatter

cd qmljsreformatter
mkdir build && cd build

# Original (from Qt Creator source code) version of qmljsreformatter
{SOMEWHERE}/Qt5.12.8.static/bin/qmake ..
# or the Orange version
# $ {SOMEWHERE}/Qt5.12.8.static/bin/qmake .. CONFIG+=ORANGE

make -j 4 # (or more jobs if possible)

How to use qmljsreformatter

Considering the following Example.qml file:

// Example.qml
import QtQuick 2.0
Item{property int id:5;Component.onCompleted:{console.log("Completed!")}
                       }

Run qmljsreformatter to create a new file:

./qmljsreformatter Example.qml Example.new.qml

or to overwrite the source file:

./qmljsreformatter Example.qml Example.qml

The resulting file will be reformatted that way:

// Example.qml
import QtQuick 2.0

Item {
    property int id: 5
    Component.onCompleted: {
        console.log("Completed!")
    }
}

Note: If qmljsreformatter has been built with the Orange configuration, the resulting file will have semicolons (;) at the end of all the JavaScript statements. This last will then be reformatted that way:

// Example.qml
import QtQuick 2.0

Item {
    property int id: 5
    Component.onCompleted: {
        console.log("Completed!");
    }
}

How to run the tests

The tests are only valid if qmljsreformatter is compiled with the Orange configuration.

cd qmljsreformatter/tests
./run-tests.sh

It is also possible to run a specific test. The following commands will execute the tests contained in of the Header.test.qml file.

cd qmljsreformatter/tests
./run-test.sh Header
[OK] Header.test.qml
