Start-reset markup language
A start-reset markup language is a fairly common type of esoteric markup language supported by many primitive chat platforms (namely, IRC and Minecraft) that uses a "start formatting" and "reset all formatting" syntax for its markup. An example of this formatting type that uses the "\" character as a formatting starter is:
| Syntax | Effect |
|---|---|
| \u | Underline all text starting from here |
| \b | Embolden all text starting from here |
| \i | Italicize all text starting from here |
| \[bg=#RRGGBBAA] | Set the background color of all text starting from here to #RRGGBBAA |
| \[fg=#RRGGBBAA] | Set the foreground color of all text starting from here to #RRGGBBAA |
| \r | Reset all formatting to the default (transparent background, black foreground, no italic, bold, or underline) |
This seems like an utterly stupid sort markup language- every time you reset, you have to start all formatting you want to continue over again- but it's actually used quite commonly, most notably in Minecraft and on IRC.
