Wrapping Long Lines

The word wrap feature splits lines at word boundaries in order to fit text within a specified wrap margin. A word boundary, for the purposes of word wrap, means whitespace. Long lines without whitespace are currently not wrapped by jEdit. The wrap margin position is indicated in the text are as a faint blue vertical line. There are two “wrap modes”, “soft” and “hard”; they are described below. The current wrap mode is shown in the status bar; see the section called “The Status Bar”. The wrap mode can be changed in one of the following ways:

• On a global or mode-specific basis in the Editing pane of the Utilities> Options dialog box. See the section called “The Editing Pane”.

• In the current buffer for the duration of the editing session,

  • By clicking the status bar indicator.

  • In the Utilities>Buffer Options dialog box. See the section called “The Buffer Options Dialog Box”.

  • From the keyboard, if a keyboard shortcut has been assigned to the Built-in Command for Toggle Word Wrap in the Shortcuts pane of Global Options. By default, this command does not have a keyboard shortcut, or appear in any menu.

• In the current buffer for future editing sessions by placing the following in one of the first or last 10 lines of the buffer, where mode is either “none”, “soft” or “hard”, and column is the desired wrap margin:

  :wrap=mode:maxLineLen=column:

Soft Wrap

In soft wrap mode, lines are automatically wrapped when displayed on screen. Newlines are not inserted at the wrap positions, and the wrapping is automatically updated when text is inserted or removed.

If the margin is set to 0, then the width of the text area window is used to determine where to wrap lines.

If end of line markers are enabled in the Text Area pane of the Utilities>Options dialog box, a colon (“:”) is painted at the end of wrapped lines. See the section called “The Text Area Pane”.

Hard Wrap

In hard wrap mode, inserting text at the end of a line will automatically break the line if it extends beyond the wrap margin. Inserting or removing text in the middle of a line has no effect, however text can be re-wrapped using theEdit>Text>Format Paragraph command. See the section called “Working With Paragraphs”.

Hard wrap is implemented using character offsets, not screen positions, so it might not behave like you expect if a proportional-width font is being used. The text area font can be changed in the Text Area pane of the Utilities>Optionsdialog box.
