You can increase editor.maxTokenizationLineLength in settings
at the cost of performance

tho the default value is 20000?
not 1000

[Except10n]

@RedCMD

"editor.maxTokenizationLineLength": 50000

After setting, the problem still exists

[RedCMD]

what language are you using?
and can we have a copy of your file please

[Except10n]

a.js.zip

use javascript
maxTokenizationLineLength It didn't seem to work

[RedCMD]

Found it

vscode/extensions/javascript/package.json

Lines 13 to 15 in bcb6c9b

	"[javascript]": {
	"editor.maxTokenizationLineLength": 2500
	}

Was changed in Oct last year
8358d0c

I was able to change it via settings

"[javascript]": {
   "editor.maxTokenizationLineLength": 25000
},

You do need to update the js file to see changes

Would have been nice if clicking Also modified elsewhere would show the other locations

I do see this parameter, and I set it (on [javascript]) but it doesn't work

"[javascript]": {
        "editor.defaultFormatter": "esbenp.prettier-vscode",
        "editor.maxTokenizationLineLength": 25000
    },
"editor.maxTokenizationLineLength": 25000,

@rzhao271 for #162291 (comment)

@Except10n I do see this work for a 5500 length line:

	"[javascript]": {
		"editor.maxTokenizationLineLength": 6000
	},

[Except10n]

@alexr00 You can take a look at the screenshot and sample I provided. Note that one line (1001 characters) highlighting is not effective

@RedCMD that UI element actually shows a hover. Hovering over it reveals other locations where the setting has been modified. Tracking issue for UX improvements: #159088
