Reformatting Source Code
RubyMine lets you reformat source code to meet the requirements of your code style. RubyMine will lay out spacing, indents, keywords etc. Reformatting can apply to the selected text, entire file, or entire project.
It is also possible to apply reformatting to the parts of the source code only, using the formatting markers.
Reformatting the code of a directory
To reformat code for a directory, follow these steps:
- In the Project tool window, select the directory you want to apply your reformatting to.
- Choose on the main menu or press Ctrl+Alt+L.
Alternatively, in the Project Tool Window, right-click the directory and from the context menu, select .
- In the Reformat Code dialog box, specify the necessary options and filters for your reformatting and click Run.
Reformatting the code of the current file
To reformat code for the current file, follow these steps:
- In the editor of the currently opened file, press Ctrl+Shift+Alt+L.
Note that if you select from the main menu or press Ctrl+Alt+L, RubyMine will try to reformat the source code automatically without opening the Reformat File dialog.
- In the Reformat File dialog, specify options for the reformatting and click Run.
Skipping a region when reformatting source code
To enable formatter markers, make sure to select the check box Enable formatter markers in comments in the Code Style page of the Settings/Preferences dialog, and type the markers in the Formatter off/on fields.
To skip a certain region on reformatting, follow these steps:
- At the beginning of the region, create a line comment (Ctrl+Slash), and then manually type the marker specified in the Formatter off field of Code Style page.
- At the end of the region, create a line comment (Ctrl+Slash), and then manually type the marker specified in the Formatter on field of Code Style page.
- Perform code reformatting, as described above.
Alternatively, create a live template to surround a block of code with formatter off/on markers, see Creating and Editing Live Templates.
