change keymap in pdf viewer

[PPanter92]

I change my scrollkeys to ijkl in normal, visual and insert mode, and for ace editor as well but when I open a PDF via the included js viewer it uses the default keymap. Is it possible to change the 'pdf keymap' somehow?

I bump this. keys mapped by mapkey() don't appear on pdf viewer.

This is because that unsafe-eval was removed from content_security_policy in manifest.json.

And for security reason, there is no possibility to bring it back.

Could you explain the problem? What's the difference in loading settings between the internal PDF viewer and another website?
I assume it could be fixed by adding unsafe-eval again which you want to avoid?
Is it a pdf.js issue that maybe has been fixed? mozilla/pdf.js#10387

The pdf viewer has its URL as chrome-extension://gfbliohnnapiefjpjlpjnehglfpaknnc/pages/pdf_viewer.html, which is a built-in page from SurfingKeys, and its content security policy is specified in manifest.json, which does not allow unsafe-eval.

But to load custom user script need unsafe-eval on built-in pages, please see https://github.com/brookhong/Surfingkeys/blob/master/content_scripts/content_scripts.js#L302

Yes, adding unsafe-eval back again could solve the issue, but Add-ons for Firefox (en-US) won't accpet that. Please see https://github.com/brookhong/Surfingkeys/blob/master/pages/changelog.md#0919

My main issue with the default pdf keymap is #1226

Instead of using full-blown eval could we do a mini-interpreter that maybe only filters out simple map(x, y) statements (which are easy to parse) and executes them? That should avoid the need for unsafe-eval and still support simple remappings in the pdf viewer.
