Re: [ESS] How can one tell rlang not to mess up R session in ESS ?
For completeness, and without any time yet to dig into Lionel's nord
modification, and as a friend who saw thread asked: what I ended up doing was
following the hint about cli and NO_COLOR and now (conditionally) set
## No color from cli inside emacs
##
https://cli.r-lib.org/reference/faq.html#how-do-i-turn-off-ansi-colors-and-styles-
if (Sys.getenv("INSIDE_EMACS") != "")
Sys.setenv(NO_COLOR="TRUE")
That preserves cli behavior on the command-line etc but now prevents it from
turning my R buffer under ESS in Emacs unreadable should I encounter an
error. And that is good enough for now.
Thanks again, Dirk

As I wrote in my message starting the thread:
Casual searching at the rlang repo doesn't reveal anything so pardon me for
asking here but what is a simple way to tell rlang to NOT do fancy pants
color error backtraces? At least under the theme I use ("nord", for Emacs)
it basically nixes readability by leaving a 'dark on dark' default.
I have nothing against occassional cutesy symbols (ie happy rcmdcheck user)
but I get rather unhappy each rlang decided to 'help' by rendering my current
R session unusable.

Not that I know a lot about this, but...
Despite Sys.getenv("TERM") being "dumb", Emacs can actually handle
ANSI color codes, and, e.g., I get a nice red cross sign with
> cli::cli_alert_danger("stop")
✖ stop
(which is no longer red when I copy-and-paste).
Are you suggesting that we should not be getting that by default? I
know I can still probably force it by setting options(cli.ansi = TRUE,
cli.num_colors = 256) etc.

Back to rlang and cli messing up sessions they maybe should leave alone:
would the team consider not asking the user to set NO_COLOR and rather
inspect the terminal info and refraining from damaging working setups?

Haven't restarted yet but I resorted for the blunt-but-likely-effective

See next message. Part of me still thinks rlang and cli do this wrong by
ignoring available env vars.

Re: [ESS] How can one tell rlang not to mess up R session in ESS ?
Worth noting I'm using `xterm-color` instead of `ansi-color` in my
comint buffers. IIRC the latter (which is builtin) didn't support some
features. Not sure if that could explain the bad behaviour you've
observed.

I've noticed the same ... and was very frustrated.
IIRC, I needed to restart R to get back to a usable *R* buffer.

I use it on top. This snippet comes in between loading and activation:
```
(require 'nord-theme)
(load-theme 'nord)
*snippet*
(enable-theme 'nord)
```
I have a bunch of other stuff defined in there, like:
```
(custom-theme-set-faces
'nord
`(tab-bar ((t (:background ,nord1 :height 1.0
`(tab-bar-tab ((t (:foreground ,nord6 :background ,nord9 :box
(:line-width (4 . 2) :style flat-button)
`(tab-bar-tab-inactive ((t (:foreground ,nord9 :background ,nord3
:box (:line-width (4 . 2) :style flat-button))
```
This might not be the best way of doing this, but it's been some years
since I added this and it still works.
Let me know if you're still having trouble with cli theming in ESS
(and you want it to work instead of disabling it). It might be worth
discussing in an issue on Github in that case.

Great, will play later. Do you use this instead of the nord theme, or on top
