--ignore-settings | Ignores all settings files and only takes command line options into consideration | |
-i, --inplace | Edit file in-place instead of outputting to stdout. | |
-f, --force | Continue even if an error has occurred. | |

Details
qmlformat is flexible and can be configured according to your needs.
Output
qmlformat writes the formatted version of the file to stdout. If you wish to have your file updated in-place specify the -i flag.
Grouping Properties, Functions, and Signals Together
With -n or --normalize flag, qmlformat groups all properties, functions, and signals together, instead of retaining the order you specified.
Settings File
You can configure qmlformat by including a settings file .qmlformat.ini in your project source or in the parent directories of your project source folder. A default settings file can be obtained by passing the --write-defaults flag. This generates the .qmlformat.ini file in the current working directory.
Warning: --write-defaults will overwrite any existing settings and comments!
The following settings are available in the .qmlformat.ini file:
| Setting | Default Value | Description |
|---|---|---|
| UseTabs | false | Uses tabs instead of spaces. |
| IndentWidth | 4 | How many spaces are used when indenting. |
| NewlineType | native | Overrides the new line format to use (native, macos, unix, windows). |
| NormalizeOrder | false | Reorders the attributes of the objects according to the QML coding guidelines. |
| FunctionsSpacing | false | Ensures spaces between functions (only works with normalize option). |
| ObjectsSpacing | false | Ensures spaces between objects (only works with normalize option). |
| MaxColumnWidth | -1 | Breaks the line into multiple lines if it exceeds the specified width. Use -1 to disable line wrapping (default). |
| SortImports | false | Sorts imports alphabetically. Note: This might change semantics if a given name identifies types in multiple modules. |
| SingleLineEmptyObjects | false | Writes empty objects on a single line (only works with normalize option). |
| SemicolonRule | always | Customizes the addition of semicolons at the end of JS statements (always, essential).Note: See Semicolon Rule for more details. |
Formatting a List of Files
While you can pass a list of files to be formatted as arguments, qmlformat provides -F option to format a set of files stored in a file. In this case, formatting will happen inplace.
// FileList.txt main.qml mycomponent.qml
Then, use it like
qmlformat -F FileList.txt
Note: If the file contains an invalid entry, for example, a file path that doesn't exist or a valid file path but the content is an invalid qml document, then qmlformat will error out for that particular entry. It will still format the valid file entries in place.
Warning: If you provide -F option, qmlformat will ignore the positional arguments.
Semicolon Rule
The --semicolon-rule option allows you to customize the addition of semicolons at the end of JS statements. The following values are accepted:
always- Always add semicolons (default).essential- Remove semicolons unless omitting them would cause issues.
