Glamour v2 style configuration

The ansi.StyleConfig fields, the shipped configs, and the JSON format in Glamour v2.0.1. Return to the main skill for the custom style example.

StyleConfig

A style is an ansi.StyleConfig from "charm.land/glamour/v2/ansi".

• Blocks: Document, Paragraph, BlockQuote, Heading, H1 through H6, Code, CodeBlock, List, Table, DefinitionList, HTMLBlock.
• Primitives: Text, Emph, Strong, Strikethrough, Link, LinkText, Image, Item, Enumeration, Task, HorizontalRule.

Optional fields such as colors and booleans use pointers so unset can inherit; prefixes and suffixes are strings. The custom style example sets pointer fields with new(value), which requires Go 1.26 or later; the example module uses Go 1.26.5. On an older toolchain, assign the value to a variable and take its address.

Shipped configs

"charm.land/glamour/v2/styles" exports styles.DarkStyleConfig, LightStyleConfig, PinkStyleConfig, DraculaStyleConfig, TokyoNightStyleConfig, ASCIIStyleConfig, NoTTYStyleConfig, plus styles.DefaultStyles (a map by name). The configs are values, so assigning one to a variable gives a copy that is safe to edit.

JSON styles

JSON files use the same field names in snake case (except HorizontalRule, whose key is hr) and load with WithStylesFromJSONFile(path) or WithStylesFromJSONBytes(b). The styles/ directory in the module holds the shipped JSON as reference. Colors are strings: hex or an ANSI index.
