Does anyone have any words of wisdom about this?

(Note: for amusement I tried adding \relax to the end of the

Cheers.

Hi Jim, I do not yet because it is late and I was doing my weekly
check of c.t.tex after a long day, and got the surprise to
see your bug report. To be honest I never tested usage of xintexpr
with miniltx...

.... here is a work-around

one should issue

\expandafter\let\csname ver@xintexpr.sty\endcsname\empty

before \input xintexpr.sty

I will have to
- update the test suite to incorporate miniltx
- learn about what miniltx really is
- and perhaps do a hotfix release

So can you try with this in your file:

-------------------- mnwe-xintextr.tex ---------------------
\input miniltx

\expandafter\let\csname ver@xintexpr.sty\endcsname\empty
\input xintexpr.sty

\bye
------------------------------------------------------------

Sorry for the trouble introduced at xintexpr 1.5

Best regards,

Jean-François

I need some sleep. Introduced at recent 1.4l.
1.5 is supposed to bring some internal core improvements...
....at some point perhaps in a few months

Yes, but in fact loading of xintexpr with miniltx in the past
was also broken : xinttrig and xintlog in aborted with a very
discrete message only shown in the log file.

Still with 1.4k from 3 weeks ago one sees in the log file:

> ....
> xintexpr: 2022/05/18 v1.4k Expandable expression parser (JFB)
> (./xinttrig.sty
> xinttrig: Loading should be via \input xintexpr.sty rather, aborting
> ) (./xintlog.sty
> xintlog: Loading should be via \input xintexpr.sty rather, aborting
> ))
> ....

As I never played with etex/pdftex + miniltx + xintexpr I didn't know
about that. At 1.4l there were some changes when xinttrig or xintlog
is loaded and thinks (erroneously, with miniltx, as it turns out)
xintexpr is not yet loaded:
1) issue a warning also visible in console output
2) try to load xintexpr

This causes the infinite loop you encountered.

At 1.4l.

I hesitate about

> - and perhaps do a hotfix release

because

1) there is the work around above and are there
.. many people actually using xintexpr+miniltx
2) I had acted already those last few days,
.. in a renewed brief (I hope) period of activity
.. in my sources the upcoming 1.5 (say before end of 2022) and
.. had already removed various deprecated things. And I may
.. introduce a new bug now if I go into a release.

On the other hand

A) I currently have implemented a nicely
.. colorized hyperlinked rendering of the source code, so
.. I am tempted into releasing that soon.

B) the infinite loop is poor taste

Best,

Jean-François

Jean-Francois,

Thanks very much for the work-around, as well as your other two messages.

Although (in general) I am not as fond of work-arounds as fixes to the
code base, I very much appreciate the efforts you have put into this
useful package, and I also appreciate your replies to my message.

In summary, I'll look forward to a fix being added to your code at
some point in the future, and your work-around gets me going again.

Cheers.

Jim

Hello Jim,

Thanks again for your bug report, it came at a good time
as I was currently active with TeX, and particularly
with xintexpr recently, not so much with the code but with
the documentation. I had been doing some clean-up with the
idea that perhaps at a later date this year I would engage
into some internal core upgrades. I was happy with the
hyperlinking added to the commented code very recently,
but felt I would
not engage soon into adding features deserving a release,
then the bug you discovered surfaced and after some thinking
it gives me the excuse for a release. It is now on CTAN
as 1.4m and should reach TeX distributions in the coming days
I guess. I had already acted some removals of deprecated
macros and decided against reverting these changes.

And the further excellent thing I owe to your report is to
let me play a bit with miniltx and I discover right now
that my LaTeX package bnumexpr can perfectly well be used
thanks to it with pdftex or etex.

Indeed all the LaTeX interface it uses (related to package loading)
seems to be supported via miniltx so one can do this

---- file to be executed with etex, or pdftex, ...
\input miniltx

\RequirePackage{bnumexpr}

\immediate\write128
{the cube of factorial(50) is \bnumeval{50!^3}}

\immediate\write128
{maybe you wanted it in hexadecimal? here it is \evaltohex{50!^3}}

% \xintLength is a bit of a pain as it does no expansion of its argument
\def\LengthAfterFExpansion#1%
{\expandafter\xintLength\expandafter{\romannumeral-`0#1}}

Sorry I can't print it here it will go into the margin because it has
\LengthAfterFExpansion{\evaltohex{50!^3}} hexadecimal digits and
\LengthAfterFExpansion{\bnumeval{50!^3}} decimal digits.

Now, I should have done
{\tt\detokenize{\edef\foo{\bnumeval{50!^3}}}} and then
{\tt\detokenize{\edef\foohex{\evaltohex{\foo}}}} and not let TeX
compute again and again the same thing, but it wasn't that long a wait.

\edef\foo{\bnumeval{50!^3}}
\immediate\write128{\meaning\foo}

\edef\foohex{\evaltohex{\foo}}
\immediate\write128{\meaning\foohex}
\bye
----

https://ctan.org/pkg/bnumexpr

loads xintkernel, xintbinhex and xintcore,
Together with its own code this "weighs" about 1/4 of
loading xintexpr, so if one only needs big integers this
may be good choice
(although it provides much less than one-fourth of the
xintexpr+xintbinhex features).

Best,

Jean-François
