Text Formatting Codes #53
Description
Original: MinicraftPlus/minicraft-plus-revived#392
Requires #26
Background
If we want the style of text looks different, it is restricted to using Unicode codes, and only colors are available, accessibility is quite limited and thus difficult to use. Also, we now have #6 for some special formatting codes. This should not be limited to just coloring when we have the ability for allowing more text styling.
Details
This feature or functionality would generally available globally, but only for rendering or displaying purposes. This would to enhance customizable visual control elements for texts. May refer to Minecraft's implementation and ANSI Select Graphic Rendition (SGR) for implementation details. Since a typeable, uncommon and displayable character must be used, it would still stick with the section sign (§). However, since it is a display character, one code for literal character should be available, which may be §§ like %% in formatter. Here, % is for parameterized texts, so it acts differently, but it might still be available for some functions.
It should not be error-prone. So, to keeping the usability of the codes without ruining the visual experience, unparsable codes will remain literal and not used for styling. This way, it could also inform the user that, the code is invalid, since it is remained literal in rendering.
For extensibility of formatting codes, allowing variety of styling, the implementation might be similar to the SGR. Specifically, they would less likely be just one-character codes, especially when color codes could be supported.
Examples
Format: §<sequences>;
<sequences> can contain one or more formatting codes with colon (:) separators. Likely they are mostly numbers instead of letters due to extensibility, unless there would be options for particular styles.
| Sequence | Name | Note |
|---|---|---|
| 0 | Reset | Clear all attributes |
| 1 | Bold | |
| 2 | Italic | |
| 3 | Underline | |
| 4 | Strikethrough | |
| 11 | Not bold | Clear bold attribute if it is set |
| 12 | Not italic | Clear italic attribute if it is set |
| 13 | Not underline | Clear underline attribute if it is set |
| 14 | Not strikethrough | Clear strikethrough attribute if it is set |
| 20 | Reversed | Reverse video |
| 21 | Not reversed | Clear reversed attribute if it is set |
| 30 | Default foreground color | Clear set foreground color attribute |
| 31- c | Set foreground color | Set foreground color by 0-f as seen in Minecraft's one |
| 32 | Default background color | Clear set background color attribute |
| 33- c | Set background color | Set background color by 0-f as seen in Minecraft's one |
Format: §^<code>;
This would help inputting some special characters, but also help displaying.
| Code | Character |
|---|---|
| 0 | § |
| 1 | (EM SPACE) |
Different ideas are welcome, even using a different format of control sequent codes.
