Foobar2000 Title Formatting Syntax

Provides syntax highlighting and code snippets for Foobar2000 title formatting scripts.

Handles all scripting related to Foobar2000 native tags and functions, as well as those of ColumnsUI.

Features

Syntax highlighting

All elements of the title-formatting syntax are recognized: comments, text, functions, tags, constants, and conditional blocks.

• Functions are highlighted in two ways:
  • Predefined functions (recognized by Foobar2000) are colored as valid functions.
  • Unrecognized functions (not supported by Foobar2000) are highlighted as errors.
• Tags are colored differently depending on their type:
  • Predefined tags use one color.
  • User-defined tags (custom tags) use a distinct color to differentiate them from the standard ones.

Snippets

Complete code snippets are provided for all tags and functions.

Commands

The plugin provides the command Join Lines Smart to group a block of code into a single line. This is useful when a complex script has been written on multiple lines of text but needs to be copied into a single line of input text in the Foobar2000 interface.

• Keybindings: Ctrl+K Ctrl+Z (Cmd+K Cmd+Z on Mac)
• Command Palette: Shift + Command + P (Mac) Ctrl + Shift + P (Windows/Linux) then type Join Lines Smart

Note: This command is only available in files with the .f2k extension.

Usage

Open a file with the .f2k extension to activate syntax highlighting, snippets and commands.
