[9fans] where's that nice plan 9 pdf previewer from iwp9 ?

[Ron Minnich]

I have a pdf, created by troff, that causes OSX preview to explode
when I try to select text. 100%. It's instant. It's funny.

I want that plan 9 pdf previewer I saw the IWP9 talk on :-)

It's in the pdffs repo. Started working on it again a few months ago, but
my laptop broke; just got a 9 system set up on a pinebook using
QEMU+KVM, I'm more than happy to guide through it and assist with
debugging if needed :)

https://shithub.us/sigrid/pdffs/HEAD/info.html is the canonical repo,
though there's a regression I fixed on
https://git.sr.ht/~pixelherodev/pdffs

I fixed up the patch to push it upstream, but forgot to do so; it's on
my list for today.

You'll need to install that `pdffs` tool, though currently it's a CLI
and not a fs, as pdf infra is more important than tacking on the 9p
interface; there's a pdf2txt script in the repo that dumps the text from
a pdf; pdfpages.rc will, additionally, do that conversion _per page_,
and then print out each page number which includes the relevant text.

If there's any other questions or anything else you need help with,
lemme know!

I know about page, I use it, but I thought pdffs was very nice, so
wanted to keep track of it.

The talk on it was great. I learned things about pdf I never knew.

I finally watched the pdffs video. Very inspiring!

Random thought:
May be this can be extended/evolved into a "displayPDF kernel", which
can open up other uses such as a GUI, a better windowing system etc.

I'm sure you guys must've thought of such things!

It is a WIP with kerTeX (and I hope I'd be able to explain this during IWP9 11th) 
to put all the pieces together:

- Have the TeX (in fact: prote, a modification, written by me, that
provides the supplementary primitives needed by LaTeX) engine do the
layout;

- Have the METAFONT extracted routines doing the RIP.

A first step will be to make TeX able to be used as roff (the roff
macros will stay the same, but this will be TeX that will do the macro
handling---not the other text utils---and DVI will be extended for the two
missing roff primitives), and to see, after, how far can TeX be used to
process an xml based (html) language (like any macro set in fact).

I find it always useful to try to push something to the limits (to
assess them)---may be funny; I mean: Peter principle: a general
practioner knows few on a lot of things; a specialist knows a
lot on few things; take to the limit: the general
practitioner knows nothing about everything, while the specialist
knows everything about nothing.
