How can I enable syntax highlighting in whole length of a line

These magenta characters at the end of long lines are confusing

It’s Prelude

Summoning @bozhidar 😉

Looks like you have some rules set up for colors past the 80 character limit.

yeah, default Prelude rules 🙂

This is where you’ll want to look to disable that. https://github.com/bbatsov/prelude/blob/555abd9a2fe3f55a0cb35d4b58f54d6cc32cebc6/core/prelude-editor.el#L346

My guess is that if you simply redefine it to not include lines-tail it will solve your problem.

^

you probably want to keep the other ones 🙂

also you can reconfigure the font locking to just do a background instead of also front

Probably some useful emacs to learn: type such a long line, go on the thing you don’t like how it’s colored

M-x describe-char

There are text properties here:
  cider-locals         [Show]
  face                 (whitespace-line)
  fontified            t
  help-echo            cider--help-echo

click on whitespace-line, it will take you to the part where you can configure it 🙂

it is probably themed

@niamu:

(setq whitespace-line-column 160)

hehe

seems you don’t really need me

@jan.zy: that is not the part you want to configure (also probably not setq)

🙂

if you just want to see it go away, M-x whitespace-mode, but as we discussed some parts are useful 😉

I am pretty sure that there is one var where I can pick another number

ok, I am in a whitespace-line

https://github.com/bbatsov/prelude/blob/555abd9a2fe3f55a0cb35d4b58f54d6cc32cebc6/core/prelude-editor.el#L347

if you just want the whitespace highlighting for long lines to be less obtrusive, change the face; if you don’t want it at all, change what whitespace-mode highlights on, if you actually just want it to complain at 160….

Face: whitespace-line (sample) (customize this face)

yeah, this is what you want to change

“customize this face"

maybe you even want to disable this

I just want to disable it

basically you just need a setq in your personal config

or you can also disable whitespace mode

@jan.zy: entirely, or just for long lines

@bozhidar: I would expect that to live in customize

just for long lines

https://github.com/bbatsov/prelude/blob/74b2b766180793409df77d65b8bf0115f3df45f4/README.md#disabling-whitespace-mode

it lives there, but I never use customize

I hate its horrible UI

and prefer to simply set stuff with setq

so if i want to disable whitespace highlighting for long lines only then I should customize the whitespace-line face?

just making sure if i understood you correctly

@jan.zy: No; I thought what you were asking was about not breaking syntax highlighting

if you just want it to be e.g. a lighter background, but still tell you, then you want to customize the face

ah, i see the difference.

if you just want to disable that portion of whitespace-mode, see bozhidar’s link, or customize that

bozhidar’s link tells how to disable whitespace mode completely and i would like to disable only this one feature 🙂

ok, I’ll just take a closer look at the source code

ahh

(setq whitespace-line-column 1000)

thanks for help !

@bozhidar: I wonder if that’s why I can’t seem to get customize to actually honor my customization for that face

oh, wait, you don’t set whitespace-line-face

@jan.zy: you could have also re-evaluated this sexp with C-M-x

I did that but I had to reload the file anyway

I go into customize, change the face, save, nothing changes, close customize, go back to the highlighted char, describe-char — customize has the foreground color in the face again

huh, I didn’t realize themes could take precedence over customizations

I mean, apart from the obvious “themes are lisp code so they do whatever they want"
