@DavidCarlisle, OK, this is starting to make sense now. Thank you. Good point on using \let, I'll look into it and give it a try. I need to save digits one by one, so I went with \chardef for treating each digit as character, using \let never crossed my mind.

David Carlisle

07:46

@bp2017 if you want to save 1 you could do \chardef\fooa`1 or \let\foob1 or \def\fooc{1} the first is a chardef token the second is an implicit character token (so also holds the catcode at the point of definition, so \bgroup opens a group, rather than typesetting a {) and the third expands back to the original token (so is the only one that outputs 1 if you do \typeout{\fooa\foob\fooc} so as I said before it depends what you are doing with the saved tokens

David Carlisle

07:59

\documentclass{article}

\begin{document}

\chardef\fooa=`1
\let\foob=1
\def\fooc{1}

Anum: \count0=\fooa\fooa\ \the\count0

% error Bnum: \count0=\foob\foob\ \the\count0

Cnum: \count0=\fooc\fooc\ \the\count0

\typeout{A: \fooa}
\typeout{B: \foob}
\typeout{C: \fooc}

A: \fooa

B: \foob

C: \fooc

@PauloCereda I'm waiting for @DavidCarlisle replying dinner

Paulo Cereda

@CarLaTeX you are mean

David Carlisle

@CarLaTeX Pineapple pizza for dinner!

@CarLaTeX done.

Dr. Manuel Kuehner

09:20

@epR8GaYuh Good post edit work :)

Ulrike Fischer

@Dr.ManuelKuehner you can't ping people from here, which haven't been in the chat.

David Carlisle

@Dr.ManuelKuehner basically here, as on the main site, if the name isn't offered when you type @ the ping will not work

Dr. Manuel Kuehner

09:58

@UlrikeFischer Ok, Thanks. I was (wrongly :)) assuming that they will be notified.

@DavidCarlisle All clear, thanks for the info.

@CarLaTeX you are mean

Paulo Cereda

12:00

Argh, PDF preview in High Sierra is blurred.

Had to use pdfpc instead of Skim or Preview.

David Carlisle

@PauloCereda you could use acrobat in windows

Paulo Cereda

@DavidCarlisle Ironically, it would be a good choice. :)

Ulrike Fischer

12:20

@DavidCarlisle @JosephWright @MarcelKrüger:

This is LuaHBTeX, Version 1.11.2 (MiKTeX 2.9.7250 64-bit) (format=luahblatex 2019.11.12)

David Carlisle

12:48

@UlrikeFischer does miktex have latex-dev formats?

Ulrike Fischer

@DavidCarlisle yes.

David Carlisle

@UlrikeFischer so would be good if lualatex-dev used that (especially if we get same into texlive)

Ulrike Fischer

@DavidCarlisle yes, I already have it on the agenda: when texlive has it, I will write Christian.

Ulrike Fischer

13:03

@DavidCarlisle can you measure how luahblatex compares to lualatex if harf-mode is not involved? In miktex I see no difference (if there is one luahbtex seems to be a tiny bit faster), in texlive I would have to unify the formats first.

David Carlisle

13:20

@UlrikeFischer not today, also bit of an unfair test as currently I take luatex from texlive but compile luahbtex (which I have not tried for a while) and I wouldn't put total faith in my build system that I have all the right libs at same versions, just as long as I have enough that it builds:-)

Ulrike Fischer

13:34

@DavidCarlisle I ran a few tests with luatex 1.10 and luatex 1.11 and luahbtex 1.11, but I get the same as on miktex: there is no noticible difference (I was wondering if there will be requests for a lualatex-light ...).

David Carlisle

@UlrikeFischer the secret plan will speed it up so much more no one will notice any overhead from hb

mickep

ohh, secret plans.

David Carlisle

@mickep shhh it's a secret.

Paulo Cereda

@mickep ooh

@DavidCarlisle ooh

Skillmon

13:58

AAAAHHHHHH, we're out for maintenance.

David Carlisle

@PauloCereda how will @Rmano ever catch up?

Paulo Cereda

@DavidCarlisle oh

yo'

@PauloCereda ^^ first snowfall tonight :)

Paulo Cereda

@yo' yay!

Wait a minute, that's cold!

yo'

@PauloCereda no, it's too hot. -3C feels much warmer because the air is less humid...

Paulo Cereda

14:03

brrrr

yo'

@PauloCereda when you come.to Europe, I see you need some Finnish sauna, with the hot air inside, and cooling down in a frozen lake outside...

Paulo Cereda

@yo' oh my

yo'

It feels so nice! It's not feeling cold really to spend 2 minues ina freeznig water after being at 95C for 10 minutes.

Paulo Cereda

@yo' ooh :)

David Carlisle

@PauloCereda you see the plan. It will be very unpleasant and uncomfortable, but it won't seem so bad because helpfully they will make it even more unpleasant just before that, so it will seem like an improvement.

Ulrike Fischer

14:21

@DavidCarlisle the python discussion on the texlive list reminded me of our two man-files in luaotfload. Do you know any sensible workflow and source format that would allow us to get rid of the python dependency? I couldn't compile them with python 3 on my system, something doesn't work in the docutils here.

Marcel Krüger

@UlrikeFischer I currently only have versions with debugging symbols, so they might show slightly different performance but I would not expect it to affect the relative performance. Here, luatex and luahbtex with plain format have no measurable difference, for latex luahblatex seems to be slightly faster (about 0.01 seconds, so nothing significant)

That corresponds to the behavior I would expect: With LaTeX, luaotfload is loaded which tries to find luaharfbuzz. On luahblatex it is just found, on lualatex it will not find luaharfbuzz and therefore do a kpse search for the dynamic module, leading to a small overhead.

Paulo Cereda

@DavidCarlisle ooh

Marcel Krüger

@UlrikeFischer The more important difference is the binary size: luatex has 20 MB, luahbtex is significantly bigger with 37 MB.

Paulo Cereda

@MarcelKrüger the final, stripped version?

David Carlisle

@PauloCereda so no port to a 640K emtex msdos machine then :(

Paulo Cereda

14:30

@DavidCarlisle oh :(

Arthur is awesome

Marcel Krüger

@PauloCereda No, the debugging versions. Stripping reduces that to 8 MB and 11 MB.

Paulo Cereda

@MarcelKrüger ooh that's good, for both!

Ulrike Fischer

@MarcelKrüger on windows the dll have 5.7 and 6.4 MB. harftex was a lot larger: over 9 MB.

Marcel Krüger

@UlrikeFischer Which version of HarfTeX is this? One of the older ones or the last release?

Ulrike Fischer

I'm getting used to this wriggly scripts - I see at a glance that miktex has still luaotfload 3.1 ;-)

@MarcelKrüger that was a dll from end of june.

Marcel Krüger

14:43

@UlrikeFischer That's odd. Before June HarfTeX was quite big because it included ICU, but by the end of June that had been dropped. Maybe some different optimization options are to blame.

Ulrike Fischer

@MarcelKrüger in another folder I have a much smaller one (4.5) from november - lots of remains everywhere from the tests ;-). But imho the size is ok, xetex is bigger ;-).

David Carlisle

15:22

@PauloCereda ?

@PauloCereda oh dviasm

Paulo Cereda

@DavidCarlisle yes :)

David Carlisle

15:37

@PauloCereda rewrite it in Lua

Paulo Cereda

@DavidCarlisle ooh

Rmano

15:56

@DavidCarlisle I'll never catch up --- will not even try ;-). I can start saying uuh, but I do not really feel to it...

Paulo Cereda

16:11

@Rmano ooh

Sebastiano

Good afternoon everybody....hi

@UlrikeFischer tex.stackexchange.com/questions/516124/… For this question all works correctly. I think that Overleaf not have this package. The user after I have not informed we if have the problems with the compilation.

@DavidCarlisle Hi, David this question is off-topic. Is there a solution to write $v_y$ in Unicode? I'm using latex2unicode.herokuapp.com

barbara beeton

16:26

@yo' -- Make sure you break a big enough hole in the ice so that @PauloCereda can get back out without slicing himself up on the sharp edges.

Paulo Cereda

@barbarabeeton ooh

David Carlisle

16:46

@Sebastiano unicode doesn't have a subscript y

bp2017

@DavidCarlisle, thank you very much.
As for your question "why \chardef\foo=\numexpr`\0+#1\relax rather than just \let\foo=#1?", the \numexpr prevents user from expanding the macro with non-digit parameters:
\the\numexpr`\0+#1\relax generates error if #1 is not a number
\let\foo=#1 would have to be accompanied by a check of #1 for a numeric value

Ulrike Fischer

@DavidCarlisle secret plan to keep ctan busy?

David Carlisle

@bp2017 well yes but generating an error in the middle of a \numexpr isn't exactly a friendly interface so in practice you'd need that check anyway in real code.

@UlrikeFischer like my new package? (I just pushed it to gh)

Ulrike Fischer

@DavidCarlisle I couldn't look yet, I only got the invitation ;-)

David Carlisle

@UlrikeFischer I could post the entire package here (It is one less token than indentfirst)

AlexG

17:04

Hi, recently it became difficult to build pdf via lualatex --output-format=dvi and dvips

David Carlisle

@AlexG it's never worked reliably (if you used any font formats dvips didn't know about)

AlexG

@DavidCarlisle Can this be fixed or worked around somehow? By means of fontspec, perhaps?

Ulrike Fischer

@DavidCarlisle just looked ;-)

David Carlisle

@AlexG why use dvi output? (I did see an announcement a while back of a driver (dvipdfmx?) that had an experimental extension to luatex output but I forget where. we use dvi output in the test suite, but only with cm tfm fonts

@AlexG if you want to include OTF fonts I think you need to rewrite dvips

Ulrike Fischer

@AlexG what is the purpose? Why are you needing dvips?

AlexG

17:09

@DavidCarlisle luatex and its dynamic memory allocation is useful, sometimes.

@UlrikeFischer PSTrickery?

@UlrikeFischer large animate examples needing the dvips route.

@UlrikeFischer animate + dvisvgm

Sebastiano

@AlexG Hi, and my best regards

AlexG

@Sebastiano Hi Sebastiano.

Sebastiano

@DavidCarlisle Thank you very much for your answer that I have appreciated. I have used the table Superscript minuscule y en.wikipedia.org/wiki/Unicode_subscripts_and_superscripts

and I have created vy where y is into the row Superscript minuscule ᵃ ᵇ ᶜ ᵈ ᵉ ᶠ ᵍ ʰ ⁱ ʲ ᵏ ˡ ᵐ ⁿ ᵒ ᵖ ʳ ˢ ᵗ ᵘ ᵛ ʷ ˣ ʸ ᶻ

It could be a solution?

David Carlisle

@Sebastiano the sub/superscript block is very variable and incomplete, there you have used "modifier letter small y" I have no idea how that is supposed to b edisplayed. Why do you want to do this anyway, they are only useful for joke ransom notes, not anything typeset

@AlexG sure and if you stick to tfm fonts that should work as far as I know, has something changed?

AlexG

@DavidCarlisle MWE \documentclass{article}\begin{document}Hello!\end{document} produces an error.

Joseph Wright

17:24

@AlexG Really? dvilualatex <name>.tex works here

David Carlisle

@AlexG oops, will check later (@UlrikeFischer may have a better idea though)

Joseph Wright

@AlexG Ah, you mean in dvips not in TeX

AlexG

@JosephWright What do you mean with "not in TeX"?

Joseph Wright

@AlexG I mean the error is not from the dvilualatex run, but rather the subsequent call to dvips

AlexG

@JosephWright exactly!

dvips: dvips: Font [lmroman10-regular]:+tlig; not found; using cmr10

Joseph Wright

17:28

@AlexG That must have been the case for a while I think

David Carlisle

@AlexG you need to switch back to tfm fonts we made lualatex default to OTF latin modern in 2015

AlexG

@JosephWright Even worse with dvisvgm --font-format=woff

@DavidCarlisle :)

@DavidCarlisle @Dr.ManuelKuehner, sooner or later.

@DavidCarlisle In the projectle motion there is $v_x$ and $v_y$. I'm creating with SIVERAPP an app for the smartphone to use for my students: this is a note of my Director of my school to do understand the importance of the smarthphone for the study. This App not works with MathJaX but the best result is with Unicode. Always thank you.

David Carlisle

@Sebastiano can you use html rendering?

Sebastiano

@MarcelKrüger Hi to the creator of fontawesome5 :-) package

@DavidCarlisle I think no. Wait that I put some screenshots.

@DavidCarlisle ooh makerobust

David Carlisle

18:36

@PauloCereda impressively robust coding, don't you agree?

Paulo Cereda

@DavidCarlisle yes. :)

David Carlisle

@UlrikeFischer I could write something in Lua (although both of you have better Lua than me) . Actually I have a feeling I did write something in Lua once for those... We are about to eat, will look in a bit

Paulo Cereda

@DavidCarlisle ooh

Faheem Mitha

This is a super vague question, but does anyone have any idea for eye catching poster themes? Like - if it was hanging on a wall, your eyes would be drawn to it?

Paulo Cereda

@FaheemMitha ^^ the Simpsons did it... :)

3

Faheem Mitha

18:46

@PauloCereda I doubt that would go down well in India.

I might get arrested and prosecuted for pornography, even.

Paulo Cereda

@FaheemMitha ouch...

@FaheemMitha do you have the poster dimensions? Probably A0?

Faheem Mitha

I'm not kidding.

@PauloCereda Not really. Let me take a look at A* dimensions.

Dr. Manuel Kuehner

@AlexG Not sure if you really meant me with "sooner or later" :)

Paulo Cereda

@FaheemMitha I usually like colorful posters, specially if they have a nice background.

Skillmon

@FaheemMitha google for source engine default texture use that as background. Everybody will have eye-cancer, but everybody will have taken a look beforehand.

Faheem Mitha

18:48

Yes, maybe A0. Is that standard size for a poster?

Paulo Cereda

@FaheemMitha I think it is.

Faheem Mitha

@Skillmon The pink and black rectangles? That's certainly eye-catching.

Skillmon

@FaheemMitha yes, exactly those.

Faheem Mitha

@PauloCereda Ok, I guess I'll go with that for the moment.

@Skillmon Might give people migranes.

Paulo Cereda

@FaheemMitha color.adobe.com they have interesting colour sets that might offer ideas for your poster.

Skillmon

18:50

steamuserimages-a.akamaihd.net/ugc/931567646647212300/…

Faheem Mitha

@Skillmon I swear the screen is dancing in front of my eyes. I just hope it's a hallucination.

Skillmon

@FaheemMitha it's the texture applied to everything that has no texture assigned in the source engines map editor ("Hammer")

@FaheemMitha that way you can easily spot missing textures, but I think it's great to get attention.

Faheem Mitha

@Skillmon They could use something less aggressive.

@Skillmon That it is.

Skillmon

@FaheemMitha something else I noticed that draws attention is a fairly white poster (at least in my university), as most posters are full of colour and really over-boarding. Sometimes a clean and nice design with a few coloured elements (with signalling colours such as red) on a moderate and bright background can really stick out (this depends on the surroundings though).

Faheem Mitha

@Skillmon Interesting perspective. Red is a good color for a poster.

cis

18:57

Good evening!

What is the time at yours? (At mine 20:00 o'clock...)

That means 8:00 p.m. (Mr. Carlisle et all.) :() ;)

Skillmon

@cis 19:59

@cis now 20:00

(I should write a bot that tells the time every minute)

cis

@Skillmon Ah, very good. But I hoped for a more different example.

Faheem Mitha

12.30 am here (IST).

Skillmon

@cis 8 o'clock in the evening. (Better?)

Faheem Mitha

@Skillmon Europe?

Skillmon

19:01

@FaheemMitha CET (so yes)

cis

@FaheemMitha Yes, Germany.

@Skillmon Mr. Skillmon, I found a good tikzample for you yesterday. It is to draw an electricity plant.

Q: Electricity station in TikZ

I need to draw the following station and base . I found this question and try to do the roof part with \draw .. (a) to[..] (b). The problem is that it looks bad . % !TeX spellcheck = en_US \documentclass[crop,tikz]{standalone} \usepackage{textcomp} \usepackage{tikz} \usetikzlibrary{arrows.meta}...

tikz-pgf

Skillmon

@cis I think you overestimate my TikZ skills, there are people who are way better than I am (I'm just a beginner regarding TikZ, really). Also the current answer looks astonishing, nothing to be done about it.

cis

@Skillmon Oh!! Thats more something for Mr. Marmot @marmot .....

Skillmon

@cis Marmot is no longer active in this chat. Pinging him won't do anything most likely.

cis

@Skillmon Oh, not pleased to hear that.

AlexG

19:23

@Dr.ManuelKuehner Didn't you say you would learn Chineese in the near future? You will need more than 256 characters to write it, I guess.

Skillmon

@AlexG that sounds terrifying.

cis

I want to have more `SageTeX` in the world!

So I have to do this Python curse, ah course at YouTube... grrrr......

Dr. Manuel Kuehner

19:40

@AlexG Haha, you are right!

@AlexG Not sure if my brain can remember more than 256 characters though.

Faheem Mitha

20:16

How hard would it be to draw an image of a crashing plane in TikZ? E.g.

shutterstock.com/image-vector/plane-crash-vector-1007206468

Line drawing, except the flames should be in red.

BrainStone

20:32

How do I properly write XeLaTeX and LuaLaTeX in LateX?

David Carlisle

20:44

@BrainStone you could use the hologo package

@BrainStone although I use Xe\LaTeX and Lua\LaTeX (even though I maintain the hologo package:-)

BrainStone

@DavidCarlisle Thanks. I knew there was a package ^^

JohnnyApplesauce

21:03

Y'all know what a Turing Machine is?

And its formal description?

What do you call those wide angle brackets, and how do you make them in LaTeX?

mickep

@JohnnyApplesauce \langle and \rangle?

JohnnyApplesauce

Ha~!

ty my friendo

David Carlisle

I know what a Turing machine is, but there are various syntax, but as @mickep just said \langle \rangle perhaps

mickep

@DavidCarlisle Oh, I did not even understand that those questions were connected.

David Carlisle

@JohnnyApplesauce or just \left<...\right> (which makes the same output)

JohnnyApplesauce

21:06

Yes, I forgot to mention that this was over the tuple thing

David Carlisle

@JohnnyApplesauce you are being far too vague, there is no standard syntax here so I have no idea what brackets you want over what tuple or what syntax you are using for tuples.

Harald Hanche-Olsen

21:28

@DavidCarlisle Except for spacing?

Paulo Cereda

Quack 🦆

Harald Hanche-Olsen

@PauloCereda Sorry, I ate already.

David Carlisle

@HaraldHanche-Olsen no \left\langle and \left< are identical

@PauloCereda dinner!

Harald Hanche-Olsen

@DavidCarlisle I was referring to \left< vs just \langle (possibly preceded by \bigl or similar).

Jun 12 at 18:16, by David Carlisle

As already discussed this chat is good for secrets, @egreg will never know.

David Carlisle

@HaraldHanche-Olsen yes they would be different.

Harald Hanche-Olsen

21:47

@PauloCereda Have you looked at Présentation?

Ulrike Fischer

22:11

@DavidCarlisle shouldn't some of the eprint be removed in the bib? E.g. eprint={macros/latex/contrib/oberdiek/ifpdf.pdf}?

David Carlisle

22:22

@UlrikeFischer probably yes, mkctan is still running here, I'll see if it gets to the end then have another look.

@UlrikeFischer I should probably delete all the eprint=... fields. url={..} are already using the preferred {ctan.org/pkg form and ctan don't really like publishing the tex-archive/macros/latex/contrib/oberdiek/... forms even when they are right

Ulrike Fischer

@DavidCarlisle is the bib used somewhere to create a reference list?

David Carlisle

@UlrikeFischer hmm oberdiek-bundle.bib appears unused, oberdiek-source.bib is used in several package doc

Ulrike Fischer

@DavidCarlisle the version numbers don't look up-to-date ;-(

David Carlisle

@UlrikeFischer I suppose Heiko's original private build script must have constructed this on the fly from the sources, but it's been checked in as source here and is static and wrong....

@UlrikeFischer I will remove the eprint field and remove entries for any removed packages, so this file will shrink as we split things out

Ulrike Fischer

@DavidCarlisle carving out the dragon ;-)

David Carlisle

22:36

mkctan just finished...

@PabloGonzálezL keeping me busy?

BrainStone

I tried to find something like that, sadly didn't find anything...
Is there a way to temporarily turn off subsection numbering (both in the header and in the TOC)?

David Carlisle

@BrainStone can't you just use \subsection* ?

BrainStone

Like for one section I'd like to not have subsection numbers at all

What does that do?

David Carlisle

@BrainStone makes an unnumbered subsection

BrainStone

Oh...

Fair point

David Carlisle

22:43

@DavidCarlisle is it online? Can I run the test?

David Carlisle

@UlrikeFischer git pull then l3build check attachfile2

@UlrikeFischer is it possible to normalize those font subset prefixes (or get l3build to remove them?)

Ulrike Fischer

@DavidCarlisle just running. I could reproduce the original problem with the wrong links. In the attachfile2 docu e.g. the reference points to http://ctan.org/pkg/macros/latex/contrib/attachfile/ <<-- remark the pkg instead of texarchive, and this leads to a login page.

Bob

I have what is hopefully a very silly question someone can answer, but I am trying to reply to a comment from Schrödinger's cat on one of my questions, and his name does not auto detect when I start typing @someones_name. Im not sure what to make of this.

David Carlisle

@UlrikeFischer yes I think it was a partially implemented attempt to make ctan happy and use the /pkg form but I backed it out as the wording links to explicit pdf or dtx with full paths everywhere so it would need multiple document edits ti get right I think

@Bob link? (I could see if it pops up for me)

@UlrikeFischer that should be fixed now

Bob

22:51

@DavidCarlisle tex.stackexchange.com/questions/515904/…

@DavidCarlisle It seems to be only effecting him, I can @name other people with no issues.

BrainStone

@DavidCarlisle Can I make these subsections show up in the TOC too?

Ulrike Fischer

@DavidCarlisle the check passes for me. Wasn't there an xdvipdfmx problem?

David Carlisle

@UlrikeFischer not sure but the chunks are all the same diff, APWWDF changed to KTKDZY but isn't that just a random string anyway

Ulrike Fischer

@DavidCarlisle I found the discussion in june: chat.stackexchange.com/transcript/message/51147116#51147116 but I'm not quite sure if it was resolved.

@UlrikeFischer oh they are an hour out aren't they, both 2016-05-20, is this a time zone thing?

Ulrike Fischer

23:00

@DavidCarlisle could be. Which test was this?

@DavidCarlisle there is an option "timezone", one could perhaps add it to fix the zone, I only need to find out which values it accept.

@DavidCarlisle no I think that doesn't change the time, it only adds something at the end.

David Carlisle

@UlrikeFischer attachfile2, but luatex not xetex

@UlrikeFischer it' pretty odd that it is a 2016 date but showing differently

Ulrike Fischer

23:16

@DavidCarlisle I added \the\time to attachfile2.pvt and then run l3build check -eluatex attachfile2, the output says "660" for me.

In a normal document I get "16" (as it is 0.16 now).

Joseph Wright

@DavidCarlisle That's the fixed epoch

David Carlisle

@JosephWright yes the question is why isn't it fixed. see the diff above, it is getting a fixed 2016 date (not now) but an hour out

Joseph Wright

@DavidCarlisle That will be timezone: I think that's by-design

David Carlisle

@JosephWright can I change the design:-) reporoducible builds but only if you are in the same timezone as Ulrike doesn't really work...

Joseph Wright

@DavidCarlisle I think for reproducible build work, there's an assumption that you've picked a locale ...

David Carlisle

23:20

@JosephWright also just above is teh xetex diff showing different random font subset prefixes, I wonder if that may be easier to fix in l3build than telling xdvipdfmx how to generate the filenames

Joseph Wright

@DavidCarlisle Important time zone is the Travis-CI one, but we could ask on the TL list

@DavidCarlisle I thought that was fixed ...

David Carlisle

@JosephWright l3 build could set the locale to Z

@JosephWright @UlrikeFischer said same but I get a diff. If you pulled oberdiek could you try l3build check attachfile2 I get failure for luatex and xetex (no rush though I'm about done for tonight)

Joseph Wright

@DavidCarlisle I guess

Ulrike Fischer

@DavidCarlisle that could be related to the epoch too: to get a reproducible fontname they perhaps calculate it from the date.

David Carlisle

@UlrikeFischer I suppose I have the xdvipdfmx source and could look... but it's late (and even later for you, pesky timezones again...)

Ulrike Fischer

23:30

@DavidCarlisle yes I'm going to bed now.;-)

David Carlisle

@UlrikeFischer good night, before you go is there a pdf link checkertool I could easily run over the collection, or should I get hyperref to dump the URL to the log as it makes them?

Bob

23:44

@DavidCarlisle Any luck?

David Carlisle

@Bob sorry didn't see your ping, works for me vvvv

Bob

@DavidCarlisle Hmm that is very strange. It actually works for me as well, but only in the first comment chain (to my question). When trying to write in the comment chain to his answer it doesnt. I will just copy and paste and hope it works. Thanks for your help!

yo'

@PauloCereda ^^ so nice!

David Carlisle

@Bob I think if it doesn't prompt it won't work, better to comment where it works even if that is the "wrong" post

@bob oh no sorry you mean under his answer? you need no ping there, any comment there will notify the poster
