Color detection when using PM2 about ansis

[webdiscus]

I know that the size of ansis is important for you

This is important not so much for me as for the developers who compare many libs and one of the most important criterion is the size :-)

Your implementation adds to dist only 29 bytes, perfect!
Thank You so much!

I will publish new package now.

I know that the size of ansis is important for you, so I'm not pushing for any particular implementation, @webdiscus
Therefore, I just want to convey the idea that isTTY is missing in PM2 case, but the actual terminal can still support colors.

[RobinTail]

Or, maybe the exception could be made here, @webdiscus (probably more readable):

 const isTTY = isNextJS || isPM2 || (isDeno ? Deno.isatty(1) : stdout && 'isTTY' in stdout); 

[RobinTail]

I collected all my suggestions and ideas in PR #20 , including tests, @webdiscus .
I tested it manually on my machine using local build and linked references.
And it works.

@RobinTail

The version 3.1.0 has been released with PM2 support.
Thanks!

Hello @RobinTail

thanks for the feature request.
I will add the supports for PM2.

How many colors does PM2, truecolor, 256, 16 support?

[RobinTail]

It should depend on the actual terminal, meaning that the lines AFTER the line 47 (isTTY condition) should be executed

ansis/src/color-support.js

Lines 49 to 69 in 9f78e35

	// terminals, that support truecolor, e.g., iTerm, VSCode
	if (colorterm === 'truecolor' || colorterm === '24bit') return SPACE_TRUE_COLORS;
	// kitty is GPU based terminal emulator
	if (term === 'xterm-kitty') return SPACE_TRUE_COLORS;
	// JetBrains IDEA: JetBrains-JediTerm
	// TODO: enable truecolor output in IDEA (defaults output 256 colors) if anybody need it
	//if (env.TERMINAL_EMULATOR?.include('JediTerm')) return SPACE_TRUE_COLORS;
	// note: check for 256 colors after ENV variables such as TERM, COLORTERM, TERMINAL_EMULATOR etc.
	// terminals, that support 256 colors, e.g., native macOS terminal
	if (/-256(colou?r)?$/i.test(term)) return SPACE_256_COLORS;
	// known terminals supporting 16 colors
	if (/^screen|^tmux|^xterm|^vt[1-5][0-9]([0-9])?|^ansi|color|cygwin|linux|mintty|rxvt/i.test(
	term)) return SPACE_16_COLORS;
	// note: for unknown terminals we allow truecolor output,
	// because all terminals supporting only 16 or 256 colors have already been detected above
	return SPACE_TRUE_COLORS;

Basically, the lack of isTTY should be ignored when PM2 is detected, @webdiscus
