_AnsiColor

 _AnsiColor (name='fore')

name: style, fore, back

You could use Fore, Back and Style to get the text foreground, background and style ansi escape code. If the input is not accepted, they would return empty string ''

Some ansi escape code example:

Fore.aliceblue, Back.blue, Style.bold

('\x1b[38;2;240;248;255m', '\x1b[48;2;0;0;255m', '\x1b[01m')

Only Back and Style support uppercase.

Fore.BLACK, Back.BLACK, Style['BOLD']

('', '\x1b[48;2;0;0;0m', '\x1b[01m')

---

Fore

Basic usage:

Fore['red'], Fore.blue

('\x1b[38;2;255;0;0m', '\x1b[38;2;0;0;255m')

Other available colors are in Fore.available:

Code

def _get_background(color):
    background = (
        Back['75, 70, 75'] 
        if sum(Color[color].rgb) / 3 > 165 else 
        Back['240, 250, 250']
    )
    return background


for i, c in enumerate(Fore.available):
    background = _get_background(c)
    print(background, end='')
    end = '\n' if (i+1) % 4 == 0 else '\t'
    print(f'{Fore[c]}{c:21s}{Fore.reset}', end=end)
print(Back.reset_all)

Fore also support rgb and hex format:

Fore['(1, 2, 3)'], Fore['#ffffff'], Fore((111, 222, 55))

('\x1b[38;2;1;2;3m', '\x1b[38;2;255;255;255m', '\x1b[38;2;111;222;55m')

print(Fore['55, 244, 56'] + 'Foreground: rgb(55, 244, 56)' + Fore.reset)
print(Fore['#005000'] + 'Foreground: #005000' + Fore.reset)

Back

Basic usage:

Back['red'], Back.blue

('\x1b[48;2;255;0;0m', '\x1b[48;2;0;0;255m')

Other available colors are in Back.available:

Code

def _get_foreground(color):
    foreground = (
        Fore['5, 7, 7'] 
        if sum(Color[color].rgb) / 3 > 160 else 
        Fore['255, 250, 250']
    )
    return foreground

for i, c in enumerate(Back.available):
    foreground = _get_foreground(c)
    print(foreground, end='')
    end = '\n' if (i+1) % 4 == 0 else '\t'
    print(f'{Back[c]}{c:21s}{Back.reset}', end=end)
print(Fore.reset)

Back also support rgb and hex format:

Back['(1, 2, 3)'], Back['#ffffff'], Back((111, 222, 55))

('\x1b[48;2;1;2;3m', '\x1b[48;2;255;255;255m', '\x1b[48;2;111;222;55m')

print(Back['55, 244, 56'] + 'Background: rgb(55, 244, 56)' + Fore.reset)
print(Back['#ff5000'] + 'Background: #ff5000' + Fore.reset)

Fore and Back also support 8-bits color:

Code

for i in range(256):
    end = '\n' if (i+1)%8 == 0 else ' '*2
    print(f'{i:3}: {Back[i]}          {Back.reset}', end=end)

---

Style

Basic usage:

Style['bold'], Style.underline

('\x1b[01m', '\x1b[04m')

Only list the commonly used styles

“reset_all” and “end” would reset all the ansi escape code function

print(repr(ansi_fmt))
print(ansi_fmt + 'something123')

ansi_fmt = AnsiColor(fore=Fore.antiquewhite, back=Back['(2, 2, 2)'], style='bold').ansi_fmt
print(repr(ansi_fmt))
print(ansi_fmt + 'something123')

ansi = AnsiColor(fore=Fore['56, 12, 34'], back=(78, 90, 120), style=('bold', 'underline'))
ansi.fore, ansi.back, ansi.style

('\x1b[38;2;56;12;34m', '\x1b[48;2;78;90;120m', '\x1b[01m\x1b[04m')

ansi = AnsiColor(fore='108', back=177)
ansi.fore, ansi.back

('\x1b[38;5;108m', '\x1b[48;5;177m')
