Module:ColorParse

From Caves of Qud Wiki
Jump to: navigation, search
Template-info.png Documentation

This module parses the game's color codes in strings and formats them for the wiki. This shouldn't be directly called anymore. Use Template:Qud text instead. If the text in question has pronouns in syntax =pronouns.(pronountype)= or a similar style, use Template:Grammar.

Usage

{{#invoke: ColorParse | parse |(your text here)}}

Code:

{{#invoke: ColorParse | parse |&RS&rt&Ko&yp&Ys&Rv&ra&Kl&yi&Yn&Rn&y}}

Result:

Stopsvalinn
