Code snippet highlighter for LibreOffice.

Description

Code Highlighter 2 allows syntax highlighting over 350 languages in LibreOffice.

Code Highlighter 2 is a fork of Code Highlighter, originally created by slgobinath but no more maintained.

Usage

• Open a LibreOffice document.
• Copy and paste the code snippet where you want it:
  • Writer: either in a text frame (preferred option), in a text box, in a table cell or as plain text;
  • Calc: either in a cell or in a text box;
  • Impress and Draw: in a text box.

• Select the text or the object containing the code snippet.
• Format -> Highlight Code:
  • in the dialog, select the language and style.
• Alternatively Tools -> Highlight Code (previous settings):
  • does not open a dialog, but applies previous settings (persistent also between restarts of LO).

Tips

• Multiselection is supported: you can select several code snippets at the same time, even from different languages (choose "automatic" in this last case).
• Not all language aliases that are valide names for Code Highlighter 2 appear in the option dialog: if you don't find a language, try anyway to type its name in the combobox (try for example with "R" or with "Pascal").
• Click the "More..." button to access line numbers options.
• Uncheck line numbering option to remove unwanted line numbers, due for example to copy-pasted code.

General behaviour

• Highlighting is applied to the selected object, that can be plain text, text frame, text shape, text table cell or calc cell.
• When cursor is inside a text shape or a Calc cell, highlighting is applied to the whole shape or cell even if only a part of the text is selected.
• When cursor is inside a text frame or a text table cell, highlighting is only applied to the selected text if any, otherwise to the whole frame or cell.
• When highlighting applies to the selected text, it formats the entire paragraphs, even if selection starts after the paragraph start or ends before paragraph end.
