@JosephWright is there any documentation for eptexinputencoding ?

@JosephWright oh here translate.google.com/translate?hl=en&sl=ja&u=http://… so it does do utf-8, hmmm...

grep "\$\$" file.tex | wc -l gives med 30. It is always like this when I get the file back from my co-author. It is probably time to have "the talk"...

@mickep nah, just use \catcode\$\active\def${\stop}`

@DavidCarlisle That will probably make our collaboration a happy one, right :)

@mickep if they get miserable just send them to the link that I sent you yesterday

Joseph Wright

8:45 AM

@DavidCarlisle I'm mainly just making sure we have the somewhere

@JosephWright sure, but for lua/xe/ml/enc-tex we skip the auto loading of inputenc as they have built in encoding support, I suspect there will need to be some adjustment for that at some point, although possibly their existing macro wrappers for switching to kanji handle that already

Joseph Wright

@DavidCarlisle Ah right

@DavidCarlisle I suspect the pLaTeX code will probably do that

@mickep I usually just hit the buffer (assuming Emacs) with this

(defun fix-double-dollar-to-eqstar ()
(interactive)
(let (
(start (point))
str cover
(case-fold-search nil)
)
(save-excursion
(beginning-of-buffer)
(while (re-search-forward
(concat
"\\$\\$"
"\$\\(.*?\n?\$*\\)"
"\\$\\$"
)
nil t
)
(catch 'continue
(when (TeX-in-comment)
(goto-char (match-end 0))
(throw 'continue nil)
)
(replace-match (concat
(regexp-quote TeX-esc)
"begin{equation*}"
"\\1"
(regexp-quote TeX-esc)
"end{equation*}"
)
t
)
) ;; end catch
) ;; end while
)
)
)

Can probably be done better, but it seems to do the job just fine

@DavidCarlisle @mickep Have you seen him do that track with the Foo Fighters? Quite good.

@DavidCarlisle ^^

@daleif Have not seen, but will. Also, thanks for the emacs snippet. I will consider to use it just for this simple reason :)

@mickep Here is the original one. FF had been playing the track during warm up, and though it sounded like "smells like teen spirit", and RA was at the same festival in Tokyo and enjoying the FF concert from the side stage. Then this happened: youtube.com/watch?v=sD1vXjpZ11E. There is a better video from the reprise in the O2 arena in London: youtube.com/watch?v=IdkCEioCp24, dudes got a great voice.

This question was asked recently on Mathemtaics Meta: How to set name above a part of a matrix?

The OP wants to typeset this:

It is unclear whether they want explicitly MathJax solution (which would make it off-topic n this site) or TeX/LaTeX solution. In any case, I thought some users from this room might be able to help or at least might be aware of already existing question on TeX.SE which could be related to this.

@daleif Oh, that is simply great!

@DavidCarlisle For a question a while ago I created a method to inject a macro in each cell of a row (similar to \rowcolor), but I used two special column types for that (one for the last column). Is it possible to inject code in each cell of a row with array without the need to use special columns? (Sorry if stupid question)

@Skillmon well you need a special column type really (as does \rowcolor) but you might hide it in the interface

@PauloCereda finally a reliable distro

/me is asking: will the chat server break when I click on "load to my last message" at the top of the window? It will download gigabytes of chat messages....

@topskip click it and find out

topskip

Perhaps similar to "when you google for 'google', the internet will break"?

@topskip I think you should skip going to the top of the chat.

Your last message is too far back; please use the transcript instead - how boring

s. patroller

most click bait is boring

@mickep we could have a multi-comment conversation about cricket so that @topskip's comments scroll off the top and he can have the excitement of scrolling to his last message.

@DavidCarlisle You should be warned: I'm correcting exams, so I can be up for almost anything.

TeXnician

@DavidCarlisle You mean something you could run vim on without risking anything?

@TeXnician no one can run vim on anything

12:16 PM

@DavidCarlisle which means everyone can run vim anywhere?

Jan 12 '16 at 12:15, by David Carlisle

@PauloCereda finished your thesis?

TeXnician

@PauloCereda Hopefully not in an ArTeXmis window ;)

@TeXnician that too. :)

@DavidCarlisle oh no

Sep 29 '17 at 12:09, by Paulo Cereda

@DavidCarlisle oh yes :)

@DavidCarlisle ooh

12:29 PM

back to lectures.... (me not you:-)

@daleif @mickep It would have been more readable indented … and no Lisp programmer ever puts a parenthesis on a line by itself! But never mind that. I offer a different implementation of the same idea:

(defun /fix-double-dollar-to-eqstar ()
  (interactive)
  (save-excursion
    (beginning-of-buffer)
    (let ((ee (list "begin{equation*}" "end{equation*}")))
      (setf (cddr ee) ee) ; a circular list
      (while (search-forward "$$" nil t)
        (unless (TeX-in-comment)
          (replace-match (pop ee) t t))))))

Skillmon

@DavidCarlisle I guess I'm afraid to break things while doing so. Will take a deeper look at colortbl.sty.

@daleif Re indentation of elisp code: I just got burned myself. Do run untabify on elisp code after indenting the whole block by four spaces, before pasting in here.

@daleif @mickep My code posted above is missing backslashes. Should be "\\begin{equation*}" "\\end{equation*}" of course.

@HaraldHanche-Olsen Oh, thanks for the code!

@mickep You're welcome. Beware that it is easliy tricked by things like \verb+$$+. If it gets out of phase, it's a disaster! Always check the result, and be ready to hit the big undo button.

@HaraldHanche-Olsen thanks, my elisp is mostly ad hock, if it works.... I'd love to learn the language better, but no time...

Skillmon

@DavidCarlisle teach me tiger, how to tease you?!

1:48 PM

Look what some authors (who shall remain nameless) made me do! ↑↑↑

@HaraldHanche-Olsen been there done that (well, a similar thing)

@yo' And the D^p_{n,K} in the numerator is itself a big fraction of double integrals and square roots. Good thing they did not want it part of the same formula.

@HaraldHanche-Olsen is using a displaysum your choice?

@yo' Yes. It got too unreadable otherwise. (I think. It's been several weeks since I put it together. I just came across it now as I am looking for last minute problems to fix.)

@HaraldHanche-Olsen oh ok

1:58 PM

@yo' It's not so much the sum as the fraction following it, I think.

@HaraldHanche-Olsen yeah, I know. But it's a tradeoff (compromise) anyway, right?

@yo' It always is.

@HaraldHanche-Olsen well, it's when you have to make compromises that things are interesting, right? :)

@yo' :)

@HaraldHanche-Olsen Taylor Swift feels your pain.

@AlanMunn :) I admit I had to resort to google to get the reference.

Alan Munn

@HaraldHanche-Olsen :) Don't worry, @PauloCereda makes me do it constantly. It even has its own acronym.

@PauloCereda Yet another chat post by Paulo that requires google. (If the frequency increases I'll just shorten it to YACPPTRG.)

2:54 PM

@DavidCarlisle I tried your code and (no surprise) it works! Thanks again.

@HaraldHanche-Olsen Oh, my. Ugly mathematics! :)
