Topic: [isabelle] Superscript argument to a function

Good day,

I have a question concerning the use of superscripts as arguments to
functions. I have a function ccc_rel that has 3 arguments, and I would
like that the syntax for the first one is a superscript. (I'm working in
ZF, don't know if that is relevant.)

If I enter

notation ccc_rel (‹ccc⇧_'(_,_')›)

everything works fine until the first argument has more than one
character. If I use \<bsup>...\<esup> instead:

notation ccc_rel (‹ccc⇗_⇖'(_,_')›)

it accepts a multi-character first argument but it the PIDE does not
prettyprints the superscript.

Can I have the cake and eat it?

Dear Pedro,

I implemented basic support for this for Isabelle 2014 but it never made it into any release. It worked fine till the 2017 release, I haven’t tried the patch on later versions. If you’re interested and want to try whether the patch still works you can find it here: https://lists.cam.ac.uk/mailman/htdig/cl-isabelle-users/2014-August/msg00214.html

Dear Pedro,

I’m certainly not the most qualified to answer this. I haven’t build Isabelle from source for quite a while. I think back then I used the README_REPOSITORY file as a guide.

Concerning applying the patch, I’m not familiar with hg but in git I’d try checking out the commit mentioned in the path, apply it there and hope for merge to do it’s magic.

Hello,

Concerning applying the patch, I’m not familiar with hg but in git I’d
try checking out the commit mentioned in the path, apply it there and
hope for merge to do it’s magic.
Just in case I adapted the patch for Isabelle 2020 (last relevant commit
97ccf48c2f0c) and it works for me on some non-trivial theories with
nested subscripts and superscripts (I also don't have any previous
experience with Isabelle/Scala though)

Sample original theory source fragment:
⬚‹
also from Sucinner have
"... = - G κ⇘i+1⇙ κ⇘i+2⇙

+ int (∑x|x<m⇘κ⇘i+1⇙⇙∧x⇧♮∈vars K⇘κ⇘i+1⇙⇙.
MAX⇩0 t∈terms K⇘κ⇘i+1⇙⇙|t~P⇘κ⇘i+2⇙⇙!0. #⇘x⇧♮⇙ t *
size (σ⇘i+1⇙ x⇧♮))

- int (∑x≤(m⇘κ⇘i+1⇙⇙ - 1)⇧♯. #⇩x (P⇘κ⇘i+1⇙⇙!0) * size (σ⇘i+1⇙
x))"
(is "_ + int (∑x∈?S. ?g x) - _ = _ + int (∑x∈?T. ?h x)- _") by

Regards,
Mikhail

Dear Benedikt,

Sorry to bother you with an dumb question, but I do not know how to
build jEdit. Could you point me to some docs where I can find this?
(Note: I'm not a computer scientist but I can manage some stuff).
It seems that there have been many some movements and the patch should
be applied somewhere in

Tools/jEdit/src/syntax_style.scala,
but I could be wrong.

Best wishes,

This is great, I hope it makes it into the 2021 release.

Dear Mikhail,

I've been successfully using your patch on Isabelle2020. Though I tried
hard, I couldn't make it work for the current development version (I
only managed to make it work with non-nested scripts). Would you mind
giving me some hints on how to adapt it?

I'm about to present a formalization to other mathematicians and a
smooth notation is key.

Thank you very much in advance,

Dear Pedro,

I tried updating the patch to the current development version (attached
as ‹sub_sup_devel.patch›). After straightforward rebasing it worked for
me seemingly correctly. I did not fully understand the issue with nested
scripts, though. If you mean long (delimited, multi-symbol)
sub/superscripts, their nesting was actually not supported in the
original patch in a sense that nested script delimiters were hidden, but
ignored, and so the inner font style was unchanged (as to visually merge
with the outer script). Only one-symbol nested scripted were supported.
I tried modifying the patch to support nested delimited scripts
(attached ‹sub_sup_stack.patch›) and it also seems to work (on small
artificial tests), but I have not tested it on any realistic examples
yet

Regards,
Mikhail
