docs: add truecolor info

[bashbunni]

Not sure if this should live in the README or in a dedicated docs section...
Will figure that out before merging. A review on the content itself would be
appreciated!

oh HA, I can add this back in. I thought I had accidentally added this

[bashbunni]

I don't even know if this sentence makes sense 😂 may need a lil tidy later

I think the chain of deps is more like wish -> lipgloss -> termenv

[bashbunni]

going to leave this part out for now given we're going to intro term changes soon which might include different default behaviour

[bashbunni]

Suggested change

	> Wish uses [termenv][termenv] under the hood, which will set truecolor for a few
	> Wish uses [termenv][termenv] under the hood, which will set `truecolor` for a few

[bashbunni]

Suggested change

	NO_COLOR vs CLICOLOR: if NO_COLOR is set or CLICOLOR=0 then the output should
	`NO_COLOR` vs `CLICOLOR`: if `NO_COLOR `is set or `CLICOLOR=0` then the output should

I know this might not be the ideal place to ask, but I’m lost and desperate for a solution.

We have a Wish application that displays colors perfectly when run locally. Setting environment variables like NO_COLOR or CLICOLOR=0 correctly disables the colors as expected. However, when I deploy this Wish application to the server, it doesn’t display any colors.

I’ve tried the following steps without success:

1. Tested every available terminal.

2. Set SendEnv COLORTERM in the SSH configuration.
   Given this, and the wish app running locally seems like a strong indicator that the problem is the server and not the client.

3. Added bubbletea.MiddlewareWithColorProfile(teaHandler, termenv.TrueColor) to the application.

4. Set CLICOLOR=1, and making sure NO_COLOR is not set in the container.

Despite these efforts, the application still doesn’t display colors when run on a server. Any advice on what else I could try to resolve this issue would be greatly appreciated.

This description is more concise and clearly states the problem and the steps you’ve already taken to try to resolve it.

@tartavull I successfully made the bubbletea example (PS: need to serve it on 0.0.0.0 instead of localhost) work inside a container (with no colors, as you can see in the log), and clients got colors anyway:

The trick is to use a custom renderer for your lipgloss colors. By default, it'll use the one from the current environment, which in this case is the server, not the client.

So we need to make a new renderer using the client's info and use it instead. See

wish/examples/bubbletea/main.go

Line 81 in 43884f7

renderer := bubbletea.MakeRenderer(s)

Hope that helps.

We should probably document this, too.

All this should be improved in the v2 stack of everything.

fwiw @bashbunni I pushed some updates

I think we should probably merge this
