hex colors not showing up when parsing terminal results

[journeytosilius]

Hi, we are trying to figure out why we are not getting hex values for the plotille results when parsing the output with hd on a terminal, do you know why this might happen ?

example :

I plot, setting all lines to 4bit "names" / "bright-green" the output on the terminal is correct, with all lines in green.

But when I parse it with hd I get no color code in hex :

echo ⢀⡏⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⡇⠀⠀⢰⠃⡎⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ | hd
00000000  e2 a2 80 e2 a1 8f e2 a0  80 e2 a0 80 e2 a0 80 e2  |................|
00000010  a0 80 e2 a0 80 e2 a0 80  e2 a0 80 e2 a0 80 e2 a0  |................|
00000020  80 e2 a0 80 e2 a0 80 e2  a0 80 e2 a0 80 e2 a1 87  |................|
00000030  e2 a0 80 e2 a0 80 e2 a2  b0 e2 a0 83 e2 a1 8e e2  |................|
00000040  a0 80 e2 a0 80 e2 a0 80  e2 a0 80 e2 a0 80 e2 a0  |................|
00000050  80 e2 a0 80 e2 a0 80 e2  a0 80 e2 a0 80 0a        |..............|
0000005e

do you know why this happens ?

plotille tries to figure out, if it actually should print colors. Have a look at the color-module: https://github.com/tammoippen/plotille/blob/master/plotille/_colors.py#L80 f

if it does not detect a terminal context (tty), you usually do not want to print colors, e.g. when piping into another program or redirecting into a file (those color codes are only relevant for the terminal).

If you want to inspect the codes, then write the returned str from Figure.show() into a file from within python.

i think i will add a toggle to force color output in #39 .

thanks and yes please ! this is important since if we want to embed it on an TUI, the color codes are very important

fixed it locally by removing the tty check, thanks for pointing it out :)
