Re: [NTG-context] setupregister with realpage?
Thank you, Hans! This works, I get all the correct page references! I didn't know about cont-new.mkxl to temporarily store "hacks". I assume the file is updated with each release? Is there a way to store local hacks, e.g., in texmf-local? I could not find "cont-loc" (maybe it's not a file).

I always thought that Unix used LF (\n, if I’m not wrong) to mark a new line, and Windows used CRLF (\r\n). How are new lines marked in the buffer? As \r instead of \r\n or \n?

I've got a 1.1GB document with 16000 pages, and Okular handles it just as fast as a 10 page document. Firefox at least manages to not crash when opening the document, which is better than most viewers. Okular is actually a pretty nice viewer in general. It's really fast, and it also seems to support most of these features.

Re: [NTG-context] PDF viewer
Am 23.09.22 um 02:47 schrieb Max Chernoff: I compiled a kind of wishlist what we need or look for in a new or enhanced open source PDF viewer, as discussed e.g. at the 2021 meeting. https://wiki.contextgarden.net/PDF_viewer Feel free to enhance the wiki page or discuss here. I think that pdf.js (the Firefox PDF viewer) meets most of these requirements. There are a few requirements that it doesn't meet, but it's open source and written in JavaScript, so we should be able to add anything that's missing. You’re right, pdf.js is quite good, and it’s already used by a lot of projects (browsers, editor plugins etc.) – the latter also means that you often encounter old/buggy/limited versions. Unfortunately, Firefox doesn’t register itself as a PDF viewer (at least on MacOS), that means I can’t use it easily to open a PDF from the command line (e.g. in scripts). But anyway, that could shift our focus to add/enable features for pdf.js in TeX editors. - PDF 2.0 compatible It can open PDF 2.0 files, but I doubt that it supports every single feature. I won’t expect every feature, there are too many. Actually I don’t know which features of PDF 2.0 Hans was missing in viewers. - proper color and transparency display (respect color profiles) It supports all of the PDF colour models/profiles for vectors, although it ignores embedded colour profiles in images. https://github.com/mozilla/pdf.js/issues/2856 Regular RGB and CMYK stuff works fine though. That’s a problem if you prepare PDFs for printing. Apple’s PDF library (used e.g. in Preview.app, Skim, TeXshop) also does a bad job at it, as well as Sumatra and Chrome (according to the comments to that ticket). - limited JavaScript support (no modification, no file operations) Yes, although it is quite limited: https://blog.mozilla.org/attack-and-defense/2021/10/14/implementing-form-filling-and-accessibility-in-the-firefox-pdf-viewer/ Thank you for the link! What they write about the scope of JS in pdf.js sounds good; but presentation stuff like buttons (e.g. for OCG) is probably missing. I need to check the limits of forms in pdf.js; but Mozilla even implemented XFA (e.g. Qoppa didn’t). - update on file change (configurable) Not by default in Firefox. It works fine in this extension though: https://github.com/tomoki1207/vscode-pdfviewer There it’s probably the editor framework that enables refresh. (Same experience with pdf.js in Atom.) - SyncTeX support Not in Firefox, although there are patches to enable it: https://github.com/James-Yu/LaTeX-Workshop/blob/cff1a372/viewer/components/synctex.ts https://github.com/tomoki1207/vscode-pdfviewer/blob/92fecdb8/src/pdfPreview.ts One of the Atom plugins was supposed to have it, but it didn’t work... (SyncTeX with ConTeXt is special anyway, we need to look into that again.) - accessibility (e.g. alternative text must work) I've never used it, but it looks like there's good support: https://blog.mozilla.org/attack-and-defense/2021/10/14/implementing-form-filling-and-accessibility-in-the-firefox-pdf-viewer/ Sounds good. - JS for controlling optional content groups (OCGs, Viewer Layers) You can toggle all the layers in the side panel. I don't think that you can toggle via buttons or JS though. Same as in Okular. OCG control via JS would enable stepwise presentations and simple animations. - inner- and inter-document links must work Yes; however, inter-document links are sometimes limited depending for security reasons. I'm sure that this can be configured though. Of course; I just meant it would be handy to be able to jump between PDFs in the same directory. - multimedia support at least via links (suggestion: use “plain Rich Media” approach with OS’ default player) I don't think so, although I guess you could include a video file as an attachment. A question for Michal... - transition effects not necessary (but if the developer has fun including them, go on) No transition effects. for forms: - fill in Yes. Just checked again with current Firefox: It doesn’t work with all of my test files. - print documents with/without form contents Yes. I couldn’t find an option to print without form contents. (But usually you would want filled forms, so “with” is ok.) - same-ID fields on different pages must be synchronized No idea. If the form generally works, this does also. I listed it because it’s a problem in some viewers. - custom checkmarks/radiobuttons should work & display correctly Usually it works, sometimes it doesn't. - JS for calculations Usually it works, sometimes it doesn't. Need to check further... for annotations (correction workflow; generally just nice to have): - similar to Adobe/Foxit Reader Reading annotations works, but you can't modify anything. Ok. There’s still no PDF viewer on Linux that can handle annotations
