The first person to port LaTeX to WASM will be hailed as the messiah.

Faheem Mitha

What is WASM?

Joseph Wright

@FaheemMitha Exactly what I thought ;)

Money Oriented Programmer

WebAssembly: The spiritual successor to asm.js for representing an easier compile target to browsers from C/C++.

Harald Hanche-Olsen

webassembly.org

@MoneyOrientedProgrammer Presumably, porting mathjax to wasm should be easy. Relatively speaking, of course.

Money Oriented Programmer

@HaraldHanche-Olsen Yes. I think so.

Q: How to make an e-TeX WebAssembly with Jim Fowler's WEB/TeX pascal to WASM compiler web2js?

I have a TeX Live 2019 distribution installed on Windows 10 and want to run a preloaded LaTeX based on e-TeX (with these packages among others: Calculator, Calculus, TikZ, CircuiTikZ) under WebAssembly in a web browser. For the job I found TikZJax, which works as follows (quoted from readme.md...

Harald Hanche-Olsen

11:06

@MoneyOrientedProgrammer Amazing. I wonder how well that works in practice, though.

David Carlisle

@HaraldHanche-Olsen texlive.js (which should be slower than that works remarkably well, but I couldn't understand how to get Jim Fowler's setup working but texlivve.js was easy 9at least in chrome and firefox)

Money Oriented Programmer

11:35

@HaraldHanche-Olsen Webassembly must be much faster. medium.com/@torch2424/…

Paulo Cereda

12:07

Advice: learn to use TeX/LaTeX the correct way first. :)

Joseph Wright

@PauloCereda You thinking about graphics for learnlatex.org?

Paulo Cereda

@JosephWright Was I? Oh yes, definitely. Graphics are good. :)

Joseph Wright

@PauloCereda I'll want artwork ;)

Paulo Cereda

@JosephWright Oh no.

@JosephWright Gimme some time. :)

yo'

12:47

@JosephWright artwork, antwork, antewerk, who knows...

Joseph Wright

@yo' :)

Finally!!!

Paulo Cereda

@barbarabeeton HUZZAH!

ooh it's hazzuh backwards

barbara beeton

@PauloCereda -- Maybe ducks don't spell very well? <grin>

Paulo Cereda

@barbarabeeton oh no

TeXnician

@MoneyOrientedProgrammer Is TikZ enough? github.com/kisonecat/tikzjax

barbara beeton

@HaraldHanche-Olsen -- That's a verb, isn't it?

Ulrike Fischer

14:01

@DavidCarlisle I have good news for you: I just got a mail that we can update the fd-files of helvet etc., you can setup more repos ;-)

barbara beeton

14:14

@DavidCarlisle -- I think I have you to thank for my palindrome. You made my answer acceptable, even though you posted a different answer yourself. Thank you.

Alan Munn

14:38

Paulo Cereda

14:52

@AlanMunn ooh woof

David Carlisle

@UlrikeFischer all of psnfss ? bring it back under latex3?

@barbarabeeton shame you still misplaced the comma:-)

@UlrikeFischer NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

2

Ulrike Fischer

@DavidCarlisle for now I simply asked if we can change the fd-files and upload and he agreed. Should we ask for a complete transfer?

David Carlisle

@UlrikeFischer no lets keep it simple:-)

Ulrike Fischer

@DavidCarlisle now the Bär is hurt - he made such an effort to create something artful. Should he add some picture mode plane?

Paulo Cereda

@DavidCarlisle oh no

@DavidCarlisle you are mean

David Carlisle

15:03

@UlrikeFischer you have to write the lesson explaining the tikducks/bears/whatever code

Ulrike Fischer

@DavidCarlisle was my feeling too ;-). The structure is a bit odd, all the relevant fd-files are inside zip files.

yo'

@UlrikeFischer btw, the A looks oversized...

David Carlisle

@PauloCereda I think you posted the wrong thing there, did you mean to post:

May 30 '19 at 9:05, by David Carlisle

@UlrikeFischer you are mean

Ulrike Fischer

@yo' fourier font (cm was too large for the bear).

barbara beeton

@DavidCarlisle -- I despair of reaching six digits in my expected lifetime.

Ulrike Fischer

15:10

@DavidCarlisle I could write a lesson about how to get duck emojis with lualatex on the shirt of bears. But I have a feeling the suggestion will be rejected as not beginner friendly ;-)

yo'

@barbarabeeton oh, well, manual spacing then?

barbara beeton

@yo' -- Maybe we could apply a Romanian under-comma to the middle digit?

Paulo Cereda

@barbarabeeton ooh let's eat the comma

yo'

@barbarabeeton well, we could. But I actually intended the message for @UlrikeFischer and got distracted

Paulo Cereda

@AlanMunn ^^ a pun with comer won't have the desired effect, right? :)

barbara beeton

15:18

@yo' -- And I really should have caught that oversized "A".

yo'

@barbarabeeton too many parallel discussions going on :-) (and also, I'm at work, debugging some wicked biblatex issue)

barbara beeton

@yo' -- Multitasking ids overrated.

Rmano

@PauloCereda I vote for removing the comma completely --- or make it locale-dependent. Rationale: it's misleading in part of the world...

Paulo Cereda

@Rmano for example, in here. :)

yo'

@barbarabeeton I'm not Intel i5; I have only 1 CPU :)

Rmano

15:26

@PauloCereda ...and here. Not directly related, but this thing is a small nightmare when you have Moodle installed in Spanish but a US-student class. ;-)

Paulo Cereda

@yo' LOL

@Rmano ooh las perguntas :)

Alan Munn

@PauloCereda On a select audience only.

Paulo Cereda

@AlanMunn oh

Money Oriented Programmer

@TeXnician Rendering math equations is enough.

Harald Hanche-Olsen

@barbarabeeton indeed it is, intentionally so.

David Carlisle

15:41

@UlrikeFischer do any of the ones in ctan.org/pkg/psnfssx need updating as well?

Ulrike Fischer

@DavidCarlisle I haven't seen messages about them and at first glance I would say no. I just looking through the texlive tree to find all candidates. currently it is phv (in psnfss), pzd (psnfss) and ccfonts.

David Carlisle

@UlrikeFischer ok i was on a work seminar so couldn't really look, I guess we'll have to take the whole of psnfss to re-submit even if we just change the zip file with the fd files, ctan don't like partial updates normally

Ulrike Fischer

@DavidCarlisle Does it make sense to resubmit as zip? Can't we simply let them unpacked?

@DavidCarlisle hm I have a hit for "mc" in ctan.org/pkg/pslatex.

David Carlisle

@UlrikeFischer excellent package that, who wrote it?

@UlrikeFischer could drop the zip but main point is we probably need to take all the other stuff as well even if we re-submit it unchanged

Ulrike Fischer

15:58

@DavidCarlisle yes, and probably look for version numbers everywhere ;-(.

Harald Hanche-Olsen

@UlrikeFischer Keep calm and learn some LaTeX3

6

@DavidCarlisle ↑↑ better?

David Carlisle

@HaraldHanche-Olsen Avoid LaTeX and use a pen

2

@UlrikeFischer open an issue and assign it to Frank :-)

Harald Hanche-Olsen

@DavidCarlisle but a pen doesn't have picture mode!

Ulrike Fischer

@DavidCarlisle the naming of these old font packages is quite a mess. Where on ctan is the source for the zapfchan package??

Harald Hanche-Olsen

@DavidCarlisle but seriously, I actually own a fountain pen – and I use it regularly

David Carlisle

16:15

@UlrikeFischer is there a zapfchan package (.sty?)

Ulrike Fischer

@DavidCarlisle no only a texlive package which contains some fd-files.

@DavidCarlisle I'm just changing psnfss.

David Carlisle

@UlrikeFischer oh ok yes. isnt that in psnfss?

tlmgr info doesn't seem very zapf specific:

Ulrike Fischer

@DavidCarlisle tlmgr info 8ruzc.fd told me it is in zapfchan.

David Carlisle

$ tlmgr info zapfchan
package: zapfchan

@UlrikeFischer weird and psnfss has zapd chancery as 8rpzc.fd

Ulrike Fischer

@DavidCarlisle when cooking I call this "vergessene Zutaten". That's the stuff I wanted to put in some dish but then forgot and then it stays around until my husband asks what it is.

David Carlisle

16:29

@UlrikeFischer zapfchan has no licnce info and only a fake author name :( Online conversation are hard chat here to you in sx chat in another screen in teams to work and in whatsapp on the phone to my mum:, good job I can type so well

Ulrike Fischer

@DavidCarlisle ;-). finish your other chats first. This can wait.

yo'

16:41

@HaraldHanche-Olsen pen and ruler?

CarLaTeX

16:59

@DavidCarlisle facebook.com/fabrizio.croce.14606/videos/590188221571494

Sorry it's in Italian...

David Carlisle

@CarLaTeX and you think that is a problem for me? Notable that you don't have an Italian phrase for smart worker presumably not much call for such a phrase in normal times?

CarLaTeX

@DavidCarlisle We have "lavoro flessibile" but saying "smart work" is cooler :)

David Carlisle

@CarLaTeX I thought your way was to cruise around in open top red cars and avoid actual work smart or not. Then go home for a ham and pineapple pizza.

Ulrike Fischer

Can one tell l3build to use latex to unpack an ins file?

David Carlisle

@UlrikeFischer yes

Ulrike Fischer

17:07

@DavidCarlisle ah, unpackexe.

David Carlisle

@UlrikeFischer was just looking up the var name:-)

CarLaTeX

@DavidCarlisle I'm trying to avoid work but it persecuted me (but I manage to avoid pineapple pizza)

Ulrike Fischer

17:30

@DavidCarlisle I did setup two private repos for the two packages and send you invites. The code should be okay, I did some tests. The main question is if more version changes are needed to satisfy ctan.

Joseph Wright

@UlrikeFischer OOh, private repos

Paulo Cereda

@JosephWright ooh

Ulrike Fischer

@JosephWright only trying to update psnfss and ccfonts.

David Carlisle

@UlrikeFischer ctan don't mind having no version changes (eg updates of tools leave most unchanged) so long as some file eg the README as the version/date that you put in the upload

Joseph Wright

@UlrikeFischer Ah

I see frank is thinking about xmarks, so of

Ulrike Fischer

17:34

@DavidCarlisle I adapted the readme from ccfonts, but only changes.txt from psnfss, I wasn't quite sure about the 00readme.txt.

Joseph Wright

learnlatex.org is taking shape :)

mickep

18:57

@JosephWright I only come to an "this domain is already..." page. Do you run a demo somewhere?

Phelype Oleinik

@mickep Nothing there yet. I think Joseph means the GitHub repo: github.com/learnlatex/learnlatex.github.io

mickep

@PhelypeOleinik Ah, thanks! Looks like a good idea!

Joseph Wright

@mickep I'm only switching the CNAME once the content is actually written

mickep

@JosephWright I understand. I just got curious.

David Carlisle

19:33

@PhelypeOleinik yes but you can see the web view at learnlatex.github.io gh-pages is running already

Phelype Oleinik

@DavidCarlisle Oh, nice!

David Carlisle

@JosephWright should we add a stub table of contents so the lesson drafts appear in gh-pages, might make it easier for peopel to comment/reviee

Joseph Wright

@DavidCarlisle Yes, I was wondering about doing it using automation: fancy doing the Jekyll coding?

@DavidCarlisle I'll see if I can find time this evening to knock something up

David Carlisle

@JosephWright yes I can look at texfaq to remind myself how it works:-)

Joseph Wright

@DavidCarlisle i'm hoping you/me/Ulrike/etc. are going to do only a small amount, and most of the text will be from others

David Carlisle

19:44

@JosephWright you want first go, or I could do it?

Joseph Wright

@DavidCarlisle Thanks: I'll take the 'parallel files' plus a bit of clean-up on Jim's checkins

@DavidCarlisle If you can take the Jekyll, I'll take some other tasks

David Carlisle

@JosephWright I'll look

Pablo González L

20:38

@PhelypeOleinik e-mail respondido :-)

David Carlisle

21:24

@JosephWright added the toc code (but you added the extra lessons in the meantime:-) learnlatex.github.io

Joseph Wright

@DavidCarlisle They are going to go down somewhere in the footer or whatever: I plan to handle that from the template

David Carlisle

@JosephWright the most complicated bit (and almost all the time I just spent) is sorting 1,2,10 not 1,10,2 I'd forgotten how weird jekyll/liquid is:-) we could consider renaming the files for the lessons < 10

Joseph Wright

@DavidCarlisle Sounds reasonable: should I just do it

David Carlisle

@JosephWright I was mostly worried about confusing any contributing authors if I moved the files from under them

Joseph Wright

@DavidCarlisle It will happen during setup

David Carlisle

21:28

@JosephWright OK I'll rename, and drop a note in the mailing list

Joseph Wright

@DavidCarlisle Thanks

@DavidCarlisle Probably better long-term, means the files are easy to follow; there's a reason I chose more- for the extra files, as they come after lesson-

Sebastiano

Good evening...everybody.

Q: Teaching with LaTeX during a Pandemic: corrections

I should correct my students' handwritten exercises that them send me with a .pdf file for distance learning due to the closure of schools in Italy and I don't know for how much longer. I'm using or directly Adobe Reader using the stick notes writing the mistakes in unicode characters or using ...

tools mathjax acrobat latextools

Could you please help me open the case?Perhaps Frougon and Thérèse can help me (see the comments) Thank you all for your kindness.

David Carlisle

@Sebastiano I don't think the edit makes it any more on topic, there really isn't any tex question here,. (I see it's been re-opened which is fair enough but the original off-topic closure seems right to me)

barbara beeton

@DavidCarlisle -- Where should one report corrections? (I'd rather not even try to update anything directly; my laptop is being too obstreperous, and I'm not up to trying to deal with git until I get my new one.) [First glitch: In lesson 3, in the example, in the biblio, \bib item should be \bibitem. Too early to lay this problem on a newbie. Also, in the last sentence, "no reference is wider", better "no reference label is wider".]

Joseph Wright

@barbarabeeton Log an issue please

@barbarabeeton Things are very much in development with lots of people taking different lessons, so best to make sure everyone involved sees things

@barbarabeeton I'd bear in mind that the content is in flux: we don't even have a first draft yet

David Carlisle

@barbarabeeton if it was us writing it, just mentioning it here would work as we'd just fix but as each lesson is being written by a different person it's better to use an issue as that will ping the person who assigned that lesson to themselves

barbara beeton

22:22

@JosephWright -- I'm trying to log in. It has forgotten what I signed up for earlier, but that was probably under my AMS info. It is not accepting what I am telling it, and also isn't giving any useful feedback about what's wrong with what I'm telling it. I have carefully followed the directions.

Shamina

I was just writing this code. It showed many errors, `\[
H(z) =
\begin{cases}
\text{$ 1^{st} $ (in green) and $ 2^{nd} $ (in red)},    & $0\leq z<Z/3$\\
\text{$ 2^{nd} $ and $ 3^{rd} $ (black)},    & $Z/3\leq z<2Z/3$\\
\text{$ 2^{nd} $ and $ 1^{st} $},    & $2\leq z<Z/3$
\end{cases}
\]

Eventhough the output came as desired

Sebastiano

@DavidCarlisle I think that my question is useful...also with the tags. It is always LaTeX (priority)! Thank you very much.

barbara beeton

@JosephWright -- I assume that the message shown at the top of the browser really means what it says: "GitHub no longer supports this web browser." I'm skunked.

Sebastiano

@Shamina Hi, I have seen the microfibra...:-) what is the your previous figure? :-)

@Shamina However \text into a math formula? :(

@Shamina Try this:

\documentclass[12pt]{article}
\usepackage{amsmath,amssymb}
\begin{document}
\[
H(z) =
\begin{cases}
1^{\text{st}} \text{(in green) and }  1^{\text{st}} \text{(in green)}   & 0\leq z<Z/3\\
1^{\text{st}} \text{(in green) and }  1^{\text{st}} \text{(in green)}   & 0\leq z<Z/3
\end{cases}
\]
\end{document}

Joseph Wright

@barbarabeeton Er, what are you using?

Sebastiano

22:37

Hi to the new enter into chat. Excuse me for bad english.

@Shamina This is a screenshot of my code that you can adapt it.

barbara beeton

@JosephWright -- My laptop is a Macbook, 2009 vintage, and for various reasons not updated later than 2013. (The reasons include the fact that the last time I had anything done at the Apple store, when I obtained an ipad, the most evident outcome was that whatever they did caused my gmail account to be disabled and lost. Sorry. It's not worth going through that again. My new laptop will be native unix.)

Shamina

@Sebastiano Thanks a lot!!!

@Sebastiano No worries. Your answer was very helpful :)

David Carlisle

@barbarabeeton do you know your old user name, i couldn't see bnb or beeton account that looked like you, but just starting a new account only means giving a working email and thinking of a user name

barbara beeton

@JosephWright -- Actually, the browser (Chrome) was installed in 2018, but because of the older operating system, hasn't been updated since.

@DavidCarlisle -- Old user name was almost certainly [email protected] (I have an entry on my password clue list). But the current problem is that, no matter what I type or click on the "log in" page, nothing happens. There's a little icon near the bottom of the page that just keeps spinning. I think it's trying to tell me something, but I'm too dumb to understand what.

David Carlisle

@barbarabeeton the email address a user gives is private but the user bnb does not look like you. github.com/bnb

@barbarabeeton you should be able to go to github.com/join and give a new user name

barbara beeton

22:53

@DavidCarlisle -- Uh, yes, indeed. But the name I tried to give them was "Barbara Beeton". I sure hope there's not more than one of those ...

David Carlisle

@barbarabeeton not sure you can have a space? No just tried, you can't.

@barbarabeeton you can give your real name with a real spave later once setting up your profile but the userrname is just alphanumeric or - characters

barbara beeton

@DavidCarlisle -- okay, I'll try without, and let you know. Do you know whether special characters (like @ or +) can be used in a password? Some sites do, some don't.

Sebastiano

@Shamina Happy to help everyone. We need to be a strong, united group here.

David Carlisle

@barbarabeeton it should prompt you like this

which says Username may only contain alphanumeric characters or single hyphens, and cannot begin or end with a hyphen.

barbara beeton

@DavidCarlisle -- No. When I tried before, it didn't give any feedback whatever. But I'll try again and let you know. (Thanks for being patient. I'm getting frustrated.)

David Carlisle

23:02

@barbarabeeton for me the red box came up as soon as I added the first space. But of course I am using a newer browser (released today, actually)

barbara beeton

@DavidCarlisle -- Sorry, no change. And I tried a name with a space -- no red box. Didn't respond when I entered a carriage return. It's looking hopeless. Oh, well, new laptop is expected in a couple of weeks.

David Carlisle

@barbarabeeton it seems a very simple form Im surprised it doesn't work on even an old browser.

barbara beeton

23:17

@DavidCarlisle -- Well, I guess I'm just blessed. Thanks for trying.

barbara beeton

23:40

@JosephWright -- A while ago I asked whether our meta "often referenced questions" might be made more prominent, perhaps by adding it to the site intro. (chat.stackexchange.com/transcript/41?m=53577961#53577961) You said yes. I've just looked at the "tour" (tex.stackexchange.com/tour), and it looks like such a reference might fit right after the heading "Find a question to answer, or ask your own".

A possible insert might be something like "We have a list of "Often referenced questions" which lists particularly useful questions, indexed by topic, that already have good answers: <link>."
