Visual Settings for MUGS-UI-TUI

Overview

Visual settings will be modifiable from the top-level Settings menu. Each setting will be represented by a slider of visual fidelity ("better" at the "end" of each line, according to bidi rules). As each slider is moved, the screen will update to reflect the new setting in a sample pattern, allowing the player to confirm that the setting will work for them.

Compatibility

Symbol Repertoire

While there are intermediate glyph repertoires and additional nuance exists, this slider represents a simplified view with only the following options:

• ASCII - Pure ASCII printables

• VT100 - ASCII + VT100 box drawing (Default)

• WGL4 - Windows Glyph List 4

• UNI1 - Unicode 1.1

The "samples" for this slider will be the icon row from the MUGS logo as represented in each character set, as follows.

ASCII:

 -----    .    __,   ._
|o   o|  / \  / * \  | \
|  o  | /   \ =_,  ) =--)>
|o   o|(_,^._) /___| |_/
 -----   /_\  [____] '

VT100 (Default):

┌─────┐   .   ┌──^   ┌─.
│o   o│  / \  / * \  │  \
│  o  │ /   \ └─/  ) ┼───)>
│o   o│(_,^._)┌┴───┴┐│  /
└─────┘  /_\  └─────┘└─'

WGL4:

┌─────┐   .   ┌──^   ┌─.
│●   ●│  / \  / • \  │  \
│  ●  │ /   \ └─┘  ) ╪───)►
│●   ●│(_,^._)┌/───┴┐│  /
└─────┘  /_\  └─────┘└─´

UNI1:

┌─────┐   ∧   ╭──∧   ┌─.
│●   ●│  ╱ ╲  / • ╲  │  ╲
│  ●  │ ╱   ╲ ╰─╯  ) ╪───)►
│●   ●│(_,^._)┌╱───┴┐│  ╱
└─────┘  ╱_╲  └─────┘└─´

XXXX: Idea for higher Unicodes: decompose each of the four base icons into arrays of individual Unicode icons and emoji (dice faces, card suits, chess pieces, weapons and objects).

UNI3 (Unicode 3.2):

┌─────┐   ♠   ╭──∧   ┌─.
│⚀   ⚁│  ╱♤╲  / • ╲  │  ╲

└─────┘   ☗   └─────┘└─´

Color Support

It is assumed that ANSI attribute escapes are available, and that the support for additional escapes is monotonic:

• Mono - Monochrome attributes (bold, italic, inverse, underline)

• 4bit - 4-Bit color (8 colors + "bright" foreground variants)

• 8bit - 8-Bit color (6x6x6 color cube + 24-value greyscale) (Default)

• 24bit - 24-bit RGB color

Sample patterns for color support will be taken from the patterns/swatches used by Terminal::Tests.

XXXX: May need to individually check for support of mono attributes; support for these is rather spotty, unfortunately.
