@marmot I think you should definitely post your answer for this: tex.stackexchange.com/questions/498432/… , may be it will create something like perspective;)

@Raaja My code is too ugly. The issue is that the tikzposter class uses hardcoded distances and also makes use of the .. controls (...) and (...) .. syntax, something I never became friends with. So if I add something, then I have the choice of either writing something very shabby or rewriting some big chunks of the package.

@Raaja I never got too excited about tikzposter because there is one thing it does not allow you to do: add a tikzpicture (without nesting tikzpictures). Do you know what that means for us TikZlings? ;-)

@marmot Nevertheless, it is your call ;-).

@Raaja These days I am too discouraged. A user has reentered the scene who specializes on copying existing answers, changing one detail (like a length), and not mentioning the earlier answer at all. And gets upvoted like crazy for that.

Raaja

8:34 AM

@marmot these things always happen (it's an internet community), because of that we shouldn't back-up. As we say, first one to do the work (of course correctly) deserves the credit (with less/more upvotes per se).

@mamot Summer is here ;)

@Raaja I think chat threads are easier to follow if you use the reply feature rather than quoting the message you’re replying to. Look for the bent arrows: At the left to highlight the parent message, at the right to generate a reply. (In the mobile version you reply by first selecting the message, then using an icon near the top of the sceeen.)

Raaja

@HaraldHanche-Olsen thanks for showing me this :)

@PauloCereda ooh you can reply to yourself?

Paulo Cereda

@DavidCarlisle ooh a conundrum

Paulo Cereda

10:20 AM

emacs is quite usable when having vim bindings. :)

This spacemacs distro thingy is interesting...

Skillmon

10:34 AM

@PauloCereda You mean that bloated OS? I doubt that.

Paulo Cereda

@Skillmon it is bloated indeed. :)

@Skillmon how about the presentation, mr. rabbit?

Henri Menke

@PauloCereda I have recently started using Neovim. It's pretty nice.

Paulo Cereda

@HenriMenke Really? I heard very good things about it, and I plan to give it a try very soon. :)

Henri Menke

@PauloCereda You can use it as a drop-in replacement for Vim, but for that you have to create the file .config/nvim/init.vim with the content

set runtimepath^=~/.vim runtimepath+=~/.vim/after
let &packpath = &runtimepath
source ~/.vimrc

Paulo Cereda

@HenriMenke ooh clever! Thank you!

Henri Menke

10:39 AM

@PauloCereda If you are interested, my Neovim config is in my dotfiles repo: git.henrimenke.com/netsettings.git/tree

Paulo Cereda

@HenriMenke Thank you, I will certainly check that out. I have Janus (github.com/carlhuda/janus) set up for vim, but I think it's a bit too much. I should go with a lighter config.

Joseph Wright

@UlrikeFischer l3backend has arrived

Ulrike Fischer

@JosephWright yes, I have it already (but didn't test yet).

Paulo Cereda

@JosephWright ooh

@HenriMenke you use airline too! <3

David Carlisle

10:56 AM

@PauloCereda or emacs

Paulo Cereda

@DavidCarlisle oh no

Skillmon

@HenriMenke what are the big advantages over VIM?

Henri Menke

@Skillmon That it's actively developed.

Skillmon

@HenriMenke and is the performance comparable to VIM's?

Henri Menke

@Skillmon Same if not better.

Skillmon

10:59 AM

@HenriMenke my VIM gets updates on a regular basis in the Arch repos, doesn't seem discontinued...

Henri Menke

@Skillmon geoff.greer.fm/2015/01/15/why-neovim-is-better-than-vim

Skillmon

@PauloCereda I have 5 slides, but have to seriously consider what to tell them, the requirements are just plain stupid :(

Paulo Cereda

@Skillmon oh

Skillmon

the objectives (poorly translated to English):
- Formulate an interesting title for your research idea
- explain your research idea
- why is researching this interesting?
- try to convince potential sponsors

Ulrike Fischer

11:25 AM

@DavidCarlisle can one test if a \noalign is allowed or not?

David Carlisle

@UlrikeFischer no

Skillmon

general tips:
- create a short PowerPoint presentation (I will fail this point, mine is created using `beamer` :)
- your talk should be 4 minutes (no more, no less)
- the talk will be followed by a short discussion and assessment by the other students (who pretend to be potential sponsors)

David Carlisle

@UlrikeFischer luatex?

Skillmon

@HenriMenke good link, thanks :)

@HenriMenke but one of the things he criticises (asynchronous linting) is possible in standard VIM, too: github.com/w0rp/ale

Ulrike Fischer

11:42 AM

@DavidCarlisle pity ;-).

@DavidCarlisle no, well perhaps it would be possible to push this, but currently I'm simply wondering if I can hide a \rowcolor command ...

Henri Menke

@UlrikeFischer If you know that \noalign can only appear in an align_group, you can cheat using FFI by querying cur_group.

\directlua{
local ffi = require("ffi")
ffi.cdef[[
/* from tex/equivalents.h */
typedef enum {
    bottom_level = 0,
    simple_group,
    hbox_group,
    adjusted_hbox_group,
    vbox_group,
    vtop_group,
    align_group,
    no_align_group,
    output_group,
    math_group,
    disc_group,
    insert_group,
    vcenter_group,
    math_choice_group,
    semi_simple_group,
    math_shift_group,
    math_left_group,
    local_box_group,
    split_off_group,
    split_keep_group,
    preamble_group,

Line 44 \noalign allowed: false
Line 48 \noalign allowed: true

Harald Hanche-Olsen

@PauloCereda what – does emacs eat ducks too, now?

Ulrike Fischer

@HenriMenke hm, that's a bit overkill ;-)

David Carlisle

@HenriMenke isn't that same as just testing \ifcurrentgrouptype=6 ?

@UlrikeFischer ^^^ (if it is the same as that, it doesn't work:-)

@HenriMenke with

\noalignallowed

{\noalignallowed}

\halign{#&#\cr
A&B\cr
\noalignallowed\cr
&\noalignallowed\cr
!\noalignallowed\cr
}

\bye

and luajitex I get

Line 44 \noalign allowed: false
Line 46 \noalign allowed: false
Line 50 \noalign allowed: true
Line 51 \noalign allowed: true
Line 52 \noalign allowed: true

so two of the three true lines are wrong (@HenriMenke)

Skillmon

12:16 PM

@HenriMenke currently testing.

David Carlisle

@PauloCereda I found an emacs/neovim comparison and main con for emacs (even though they recommended neovim) was the following, could you believe this is possible, you have spacemacs.... : Con Sometimes the extensibility can distract you from your actual work If I ever want to lose half a day, I'll start by tweaking my .spacemacs config file. slant.co/versus/43/62/~emacs_vs_neovim

Skillmon

@DavidCarlisle still bloated OS!

David Carlisle

@Skillmon look my OS is X windows over cygwin over windows 10, don't tell me about bloated OS, I have the gold badge in these things:-)

Skillmon

@DavidCarlisle :) I know, still confused how you can live with it.

Henri Menke

@DavidCarlisle Yes, you are right. The only point in the LuaTeX source where no_align_cmd does not immediately lead to an error is in align_peek. I thought that checking cur_group would be sufficient and for the line !\noalignallowed\cr I am actually a bit surprised that it gives align_group. I would have expected hbox_group because I think the ! should switch to hmode.

David Carlisle

12:30 PM

@HenriMenke presumably because it's not a normal hbox but an align unset hbox thing. that is why e-tex's \currentgrouptype is more or less useless for doing anything with tables. (and why tabu is broken as it tests this all over the place, and a re-arrangement of array.sty changed the group types...)

marmot

12:51 PM

@Raaja Yes, summer is also where I am. ;-) (It is true that we cannot do much about it, but IMHO it was more fun to answer TikZ questions when percusse and cfr were still active, who did new things and were always fair. Dysfunctional sites are plenty.)

Skillmon

@HenriMenke I love the asynchronous make!

David Carlisle

1:06 PM

@Skillmon so is that like emacs has had since 1980-something?

Paulo Cereda

@DavidCarlisle oh

Raaja

1:25 PM

@marmot it is what it is ;-)

David Carlisle

@marmot forget tikz, stick to picture mode questions.

Paulo Cereda

@DavidCarlisle boo

marmot

@Raaja Yes, but have you looked e.g. on the physics site? I really do not want to go there. If I remember correctly, @AlanMunn said something similar about linguistics.

@DavidCarlisle As far as I know, all of them were answered by you. I mean both of them. ;-)

Alan Munn

1:42 PM

@marmot I just avoid the linguistics site altogether, but the site I had a bad experience with was English Language and Linguistics.

marmot

@AlanMunn I knew it was something complicated. ;-)

David Carlisle

@PauloCereda I take it that means "yes" ?

Alan Munn

@marmot When people downvote good answers to mediocre questions because the question is mediocre it's time to leave.

Paulo Cereda

@DavidCarlisle no :)

marmot

@AlanMunn Yes. Or when people confuse "physics" with "quantum mystics". ;-)

Joseph Wright

1:45 PM

@AlanMunn Urgh

Paulo Cereda

@marmot they are absolutely right and completely wrong at the same time :)

marmot

@PauloCereda Or "not even wrong", a term coined by Pauli and abused later.

Paulo Cereda

@marmot ooh

barbara beeton

@AlanMunn -- English Language Learners is rather more forgiving than English Language and Linguistics. Mathematics is also rather "impatient" of non-professional mathematicians. I prefer civility.

Alan Munn

@marmot Does that originate with Pauli? I had no idea.

marmot

1:50 PM

@PauloCereda To make @JosephWright happy you should write OHH or H_2O instead. I think OOH is not a molecule.

Alan Munn

@barbarabeeton In my case they were downvoting answers by a professional (me.)

marmot

@AlanMunn Yes, that's what I was told. Actually, I was told he said "Noch nicht mal falsch.", which translates to "Not even wrong.".

Not even wrong

"Not even wrong" is a pejorative applied to purported scientific arguments that are perceived to be based on invalid reasoning or speculative premises that can neither be proven correct nor falsified and thus cannot be discussed in a rigorous, scientific sense. For a meaningful discussion on whether a certain statement is true or false, the statement must satisfy the criterion of falsifiability, the inherent possibility for the statement to be tested and found false. In this sense, the phrase "not even wrong" is synonymous to "nonfalsifiable".The phrase is generally attributed to theoretic...

@AlanMunn Actually I am not sure if the Wikipedia article is correct when saying it means "nonfalsifiable". According to what I was told it had a somewhat different meaning originally, more something along the lines that the initial assumptions are nonsensical.

Alan Munn

@marmot Yes, I've never taken it to mean "unfalsifiable", but exactly that it's based on nonsense assumptions. That's certainly how I would use it.

barbara beeton

2:09 PM

@AlanMunn -- Understood. (In my case, I was supplying a link to the (recently made freely available) "Math into Type"; it was downvoted -- and deleted -- as a "self-serving advertisement". Fie.)

marmot

@AlanMunn Yes, but it got used (or, IMHO, abused) here. I never read the book but according to what I was told it was used as "unfalsifiable", perhaps that's why Wikipedia mentions this interpretation. (I am not interested in this discussion, though. ;-)

Raaja

2:58 PM

@marmot @physics everyone is a professor there ;) no way for a novice to live there.

Alan Munn

@marmot TikZ question: how to I use the current values of a node's inner and/or outer sep in another calculation.

Raaja

@Marijn thanks for summarising my thoughts in a more civilised fashion :)

In the Qgate question.

Ulrike Fischer

6:14 PM

@JosephWright so we now know who complained first ;-)

Joseph Wright

@UlrikeFischer :)

@UlrikeFischer I guess I should put in a note to Karl to ask for the dep to be added

Ulrike Fischer

@JosephWright and I should check if my tests fail on travis too ...

Joseph Wright

@UlrikeFischer I've pointed out to TeX Live: I'll wait for e.g. siunitx tests

@UlrikeFischer Probably I should auto-build docs for LaTeX2e as we do for LaTeX3

Ulrike Fischer

@JosephWright how many docs are there?

Skillmon

@JosephWright can you move tex.stackexchange.com/questions/498511/… to stack overflow?

Joseph Wright

6:23 PM

@UlrikeFischer Quite a few ...

@Skillmon I could, but it's going to get closed there; I'm only supposed to migrate if the question has a hope of staying open

Skillmon

@JosephWright in that case close it here?

@JosephWright thx for the comment :)

Faheem Mitha

6:43 PM

Where's the documentation for the setspace package? texdoc setspace doesn't appear to bring up anything. It might be part of LaTeX 2e, but I couldn't find anything in the 2e manual.

The closest thing to documentation I have found so far is this blog post -> texblog.org/2011/09/30/quick-note-on-line-spacing

I wound just looking at setspace.sty. There is some documentation embedded in there.

Includes references to a mysterious GDG, but we never learn who he is. His full name is never revealed.

Ulrike Fischer

7:04 PM

@FaheemMitha the full name is there.

Skillmon

@UlrikeFischer there is no full name of someone with initials GDG, the only name coming close seems to be George Greenwade

Ulrike Fischer

@Skillmon and then you do a fast google search and find e.g. tug.ctan.org/info/greenwade-tug93.tex.

Skillmon

@UlrikeFischer but the full name is not in the file (that was my only point) :)

Ulrike Fischer

@Skillmon I count firstname + lastname as fullname.

Skillmon

@UlrikeFischer ok.

This message was written using a VIM subprocess :)

Alan Munn

7:19 PM

@FaheemMitha The documentation is in the comments of the package... It's so old, but also still very much in use that I don't think the TeXLive people have had the heart to force proper documentation. For me, texdoc setspace simply brings up the package, and if you scroll through a couple of pages you'll get the actual user instructions.

@FaheemMitha I assume that's George Greenwade, (whose full name does appear once in the file) who died in 2003. He was one of the original people who set up CTAN, and was responsible for its name.

Paulo Cereda

7:46 PM

@Skillmon ooh

Skillmon

@PauloCereda still have to figure out how to use NVim instead, if I stick to it. (this was written using a VIM instance as well)

David Carlisle

8:13 PM

@AlanMunn github.com/rf-latex

Alan Munn

@DavidCarlisle Is that the new documentation? :) Or do you want me to turn the package comments into docs?

David Carlisle

@FaheemMitha what do you mean by "the 2e manual" ?

@AlanMunn it's all Robin's packages on ctan moved to github, with ctan upload rights. there are other people with write access but don't seem to have made their membership public, so I'll need to obscure their names as @gr@g or j@seph for example.

Alan Munn

@DavidCarlisle Yes, I can see that. How come footmisc isn't there? Was it taken over by someone else?

David Carlisle

@AlanMunn some bloke called Frank grabbed that

Alan Munn

@DavidCarlisle :)

David Carlisle

8:22 PM

@FaheemMitha the latex manual is split into two books, the LaTeXBook (which only deals with core distribution not contributed packages) and The LaTeXCompanion which does list (some) contributed packages, setspace gets a section in there (3.1.13, pages 106-108) So setspace gets more coverage than most contributed packages in the official manual.

David Carlisle

8:49 PM

Hmm on a scale of 1 to 10, how bad is it if your laptop turn's itself off and acts as if it has no power.....?

Ulrike Fischer

@DavidCarlisle ask Frank ...

David Carlisle

Just died on me as o sent the above .. actually it's come back up but done a hard reboot I suspect the screen hinge is shorting something out as until I fiddled with it the power button did nothing computer support in the morning....

that was on the phone, let's see if the computer keeps working:-)

@Bordaigorl interesting, I gather it's not ready yet but will be a mathpix rival when it is....

Oh! I did not know about mathpix

Jonas Stein

Did the global sx login change in the last months? I thought I could login to all my sx accounts when I am logged in on tex.sx

but this is no longer the case for me.

Sigur

10:13 PM

Suppose the command \part{faa}\chapter{foo}. What is the most simple way to save on external csv file the following pattern: faa,foo,<n>, where <n> is the page number of the part.

egreg

@Sigur What about the next chapters?

Sigur

@egreg, for sure my template contains a single chapter per part.

Multiple use of \part{faa}\chapter{foo} should produce new lines in the csv file.

I was trying to use bash script to do that from the toc file, but it is complicated.

Alan Munn

@JonasStein I haven't noticed any change. Switching to another site keeps me logged in.

@Sigur What document class?

Sigur

@AlanMunn, report.

egreg

@Sigur Sorry, but I don't understand what would be the reason for having a single chapter part.

Sigur

10:27 PM

@egreg, to be true, I am using a very old template. So, each author send me a tex file with part containing the title and chapter containing the author name (ugly, I agree). Then, when I compose everything I can produce a table of contents with titles and authors, easily.

@egreg, I know that I should update the template, but I did that years ago, and my knowledge was very limited.

You can see an example here rc.unesp.br/igce/matematica/bicmat/volume_14.pdf

egreg

\documentclass{report}
\usepackage{refcount}
\usepackage{nameref}

\newwrite\sigurwrite
\immediate\openout\sigurwrite=\jobname.ref
\AtEndDocument{\closeout\sigurwrite}

\let\latexpart\part
\let\latexchapter\chapter
\newcounter{partchapter}

\makeatletter

\renewcommand{\part}[1]{\stepcounter{partchapter}\latexpart{#1\label{p-\thepartchapter}}}
\renewcommand{\chapter}[1]{%
  \latexchapter{#1}\label{c-\thepartchapter}%
  \protected@write\sigurwrite{}{%
    \getrefbykeydefault{p-\thepartchapter}{name}{},%

@Sigur ^^^^^

Sigur

@egreg, thanks, let me study it.

egreg

@Sigur @Sigur I changed it a bit

@Sigur Now the \jobname.ref file contains faa,foo,1

Sigur

@egreg, it worked perfectly. the .ref file will be useful to create certificates. Thanks a lot.

@egreg, just one more question: what is the meaning of the 3rg argument in \getrefbykeydefault? You used {} and {0}.

egreg

10:56 PM

@Sigur It's a default when the label has not yet found its way in the .aux file. I used an empty string for textual references, 0 for the numeric one.

Sigur

@egreg, perfect.

manooooh

11:18 PM

Hello guys!!

I want to know that kind of hyphen would you use to describe a method. For example: "Use the Newton-Raphson method", or "Use the Newton--Raphson method" or...?

Thanks!

Bordaigorl

@manooooh single hyphen

double used like that is more for ranges 10--20

manooooh

@Bordaigorl hello! Oh, I wanted to use the --, but what you say it's okay

Ok

bp2017

11:54 PM

Is there a way to get a width of the current line in a paragraph shaped with \parshape? \linewidth always returns width of the page, no matter how indented the line is.

Phelype Oleinik

@bp2017 I don't use \parshape a lot, so I'm not sure, but it looks like you want e-TeX's \parshapedimen. Take a look at the end of section 3.4 of the e-TeX manual.

@bp2017 It looks like the "current line" isn't possible, because TeX doesn't know which line you are in until it broke the paragraph into lines, at which time is too late to use \parshapedimen. You can only know the length of a specific line.
