Trailing Spaces - Jetbrains

highlight trailing spaces and delete them in a flash!

This plugin is inspired by the Trailing Space extension for Visual Studio Code and the Trailing Space for Sublime Text.

Synopsis

Jetbrains provides a way to automate deletion of trailing spaces in setting. Depending on your settings, it may be more handy to just highlight them and/or delete them by hand, at any time. This plugin provides just that, and a lot of options to fine-tune the way you want to decimate trailing spaces.

Usage

Toggle Highlighting

You can toggle highlighting of trailing spaces on and off at any time using:

1. Menu: Go to "Edit / Trailing Spaces / Toggle Highlighting"
2. Keyboard Shortcut: Use Alt+Shift+D to instantly toggle highlighting
3. Settings: Use the "Enable highlighting" checkbox in the plugin settings

The action text dynamically updates to show whether it will "Enable" or "Disable" highlighting based on the current state.

Delete

The main feature you gain from using this plugin is that of deleting all trailing spaces in the currently edited document. In order to use this deletion feature, you may either:

1. Command Palette: Press Ctrl+Shift+A (or Cmd+Shift+A on Mac) and select/type "Trailing Spaces: Delete"

2. Keyboard Shortcut: The plugin comes with a default keyboard shortcut Alt+Shift+T to delete all trailing spaces at once in the current file!

3. Menu: Access the action from "Edit / Trailing Spaces / Delete"

With these options, you can quickly delete all trailing spaces in your current document whenever needed!

Settings

Several options are available to customize the plugin's behavior. Those settings are stored persistently and applied globally to all opened documents.

To access the settings: Go to "File / Settings / Tools / Trailing Spaces" (or "Preferences / Tools / Trailing Spaces" on Mac).

Enable Highlighting

Default: true

This is the master toggle for all trailing space highlighting. When disabled, no trailing spaces will be highlighted in any file. This setting can also be toggled using the "Toggle Trailing Spaces" action (Alt+Shift+D) or via the menu at "Edit / Trailing Spaces / Toggle Highlighting".

Highlight Current Line

Default: true

Highlighting of trailing spaces in the currently edited line can be annoying: each time you are about to start a new word, the space you type is matched as trailing spaces. The currently edited line can thus be ignored by disabling this option.

When this setting is disabled, trailing spaces in the line being edited will not be highlighted (only effective when " Enable Highlighting" is also enabled).

Trim On Save

Default: false

Setting this to true will ensure trailing spaces are deleted when you save your document. This feature works independently of the highlighting settings - trailing spaces will be removed on save even if highlighting is disabled.

When enabled, all trailing spaces in the document are automatically removed every time you save the file.

Custom Highlight Color

Default: #FF0000 (Red)

You can customize the color used to highlight trailing spaces by specifying a HEX color value. The plugin provides two ways to set your preferred color:

1. Color Picker: Click the "Choose" button to open a visual color picker dialog where you can select any color
2. Direct HEX Input: Enter a HEX color code directly in the text field (supports both #FF0000 and FF0000 formats)

Examples of HEX color codes:

• #FF0000 - Red (default)
• #00FF00 - Green
• #0000FF - Blue
• #FFFF00 - Yellow
• #FF00FF - Magenta

The color change applies immediately to all open documents. If an invalid color code is entered, the plugin will fall back to the default red color and log a warning.
