| 2 | // draws with. |

| 4 | // A theme is a flat map from a dotted style key, such as "syntax.keyword", to |
| 5 | // a foreground colour, a background colour and a few attributes. Lookups fall |
| 6 | // back along the dots, so a theme that only defines "syntax" still colours |
| 7 | // every token, and one that defines nothing still renders. |
| 8 | // |
| 9 | // Themes ship embedded in the binary and are also read from the user's |
| 10 | // configuration directory, where a file of the same name wins. |

| 13 | // The style keys the editor asks for. A theme need not define them all: |
| 14 | // Style falls back along the dots and finally onto KeyDefault, so a partial |

| 17 | // Keys are grouped by the widget that draws with them. Adding a widget means |
| 18 | // adding its keys here, so that this list stays the single description of what |
