Why oh why does \def\SubentryB##1{\SubentryS { #1 #2 \href{http://a.beautiful.url/?q=\percentifier{##1}}{test-lin‌k} } not work? tex.stackexchange.com/questions/395241/…

@VincentMiaEdieVerheyen why did you accept an answer if you still wanted answers, most of us don't look again at questions once they are marked as answered on the home page

@VincentMiaEdieVerheyen that would define SubentryB to have one argument but all the other variants of wipet's code that you have posted define it to have two. don't you want

\def\SubentryB##1##2{\SubentryS { ##1 ##2 \href{http://a.beautiful.url/?q=\percentifier{#1}}{test-link} } \futurelet\next\SubentryA}

but hard to guess really what you want, I can't see why you need nested definitions at all.

@DavidCarlisle That worked thanks! a lot

@DavidCarlisle Would you perhaps like to post a comment at tex.stackexchange.com/questions/395241/… ?

or an answer?

then I can upvote / accept

@DavidCarlisle I thought I need nested definitions because I have to reuse the argument of the previous command (that's why I made that previous command into an environment, and then I found out the second argument needs to be put inside that environment) ...

@ It all started from this question tex.stackexchange.com/questions/394981/… and people started saying I should change the first command into an environment instead, which is what I did ...

@DavidCarlisle I have added your solution in a comment to another answer, with a link to this message in the chat. tex.stackexchange.com/questions/395241/… I have also simplified the OP ... sorry for the mess.

David Carlisle

8:01 AM

@VincentMiaEdieVerheyen as I just put in my answer to your last question, I think the document markup that you are aiming for with an arbitrary length list {a}{b}{... evaluated in pairs is simply wrong, you can do it but the code as you see is complicated and the resulting document will be confusing.

The new top bar layout looks a bit hellish.

And quite fitting imgur doesn't work ;-(

egreg

Problems with Imgur, it seems

Ulrike Fischer

@egreg Yes.

@egreg Do you also have this dark red on black?

egreg

@UlrikeFischer Yes, I was going to post about it, but saw that Werner already did it.

@DavidCarlisle So you don't like to use/see LaTeX as a typical coding language?

David Carlisle

8:40 AM

@VincentMiaEdieVerheyen yes but in most coding languages you can not change user-syntax on the fly, with latex you can but that does not mean it's a good idea. latex lists are , separated and {} are mandatory fixed arguments [] are optional arguments.

@PauloCereda Hi Paulo! Are you well?

Paulo Cereda

@CarLaTeX Hi! Still ill, but recovering. :)

CarLaTeX

@PauloCereda Take care of yourself!

@DavidCarlisle How can I learn what I need to learn so that I don't mess up syntax all the time? The experienced users on these site know these "basics" and I have no clue.

Zarko

Hi! i just try to upload image in my answer tex.stackexchange.com/questions/395589/… however, image is not visible. shown is only a link, which is broken. is this temporary problem or it is some new features coming with new site design (which also make me troubles, i need more time to learn it :-( )

A: The rhyme and reason of function argument syntax (brackets versus braces)

Really a postscript to @Yiannis answer but the rule about the [] arguments being optional isn't unwritten it is explicit in the LaTeX Book that that is the LaTeX syntax. Using the primitive \def facilities it is possible to define commands with essentially arbitrary syntax but commands defined i...

@Zarko network wide image problems this morning

Zarko

ok, this means i need to wait a while ...

Paulo Cereda

@Zarko you could eat Pringles. :)

David Carlisle

@PauloCereda 3.0a a small step towards 4 in the same way that 2e is a small step towards 3 ? So we can expect to see arara 4 in about 2042?

Paulo Cereda

@DavidCarlisle I like this projection. :)

David Carlisle

@PauloCereda you might have finished your thesis by then as well.

Paulo Cereda

9:57 AM

@DavidCarlisle That's the plan!

Zarko

@PauloCereda, what is "pringles"? my dictionary haven't this word ...

Paulo Cereda

@Zarko oh no

Zarko

@PauloCereda, so i decided to eat one apple, my favorite fruits. and then back to my work. i will look to site after lunch :-)

Paulo Cereda

@Zarko ooh apples :)

We ducks like fruit

David Carlisle

@PauloCereda I hear oranges and duck go well together

stackexchange has gone blue again

Paulo Cereda

@DavidCarlisle Allez les Bleus?

David Carlisle

@PauloCereda Não me confunda com essas línguas estrangeiras.

Paulo Cereda

@DavidCarlisle oh

David Carlisle

@PauloCereda so, how was my Portuguese?

Paulo Cereda

@DavidCarlisle pretty good!

David Carlisle

11:05 AM

@PauloCereda as expected!

egreg

Imgur is serving images to Math.SE, but not to us.

Paulo Cereda

What has Math ever done for us?

Paulo Cereda

@TeXnician oh no

TeXnician

@PauloCereda Pineapple pizza?

Paulo Cereda

@TeXnician oh

Harald Hanche-Olsen

@TeXnician That's more a question of chemistry and taste. Mathematics can say something about cooking time, though.

barbara beeton

1:55 PM

@mickep -- a couple of months ago, you posted some comments suggesting improvements to the "short math guide", and asked if you should send mail with additional suggestions. i think i didn't answer at the time, but am actively working on that now, so if you have more comments (and haven't forgotten them), please do.

TeXnician

3:28 PM

A quick question: I flagged this answer, because Werner's comment from years ago still applies (content is fully covered by another answer there). Now the reviewers completed with "Looks OK". Is our usual strategy to keep duplicate answers?

@Kurt @StefanPinnow ^^

Joseph Wright

3:41 PM

@TeXnician I've zapped it

TeXnician

@JosephWright Ah okay, so the answer seems no?!

Joseph Wright

@TeXnician Broadly the aim is to keep the 'noise' for people looking for info to a minimum: I really don't see the extra answer helps here

David Carlisle

@JosephWright sorry I'm going to miss the start of the call tomorrow, "lunch break" is a flexible concept around here

Joseph Wright

@DavidCarlisle Understood

@DavidCarlisle I have to get back from a teaching event for the start, so that might be tight anyway (I'm teaching straight after too, so it has to be no more than about 50 minutes for me)

Paulo Cereda

4:33 PM

@DavidCarlisle ooh it means you can eat anything you want? :)

TeXnician

@PauloCereda That's se(a/e)food diet: "Whenever I see food, I must eat it" ;)

Paulo Cereda

@TeXnician ooh :)

David Carlisle

@PauloCereda er given that I make it and bring it in, then yes.

Paulo Cereda

@DavidCarlisle oh

David Carlisle

@PauloCereda This for example

@DavidCarlisle Are you in Italy?

mickep

@barbarabeeton I cannot find any unsent comments, so either 1) I did not have any further comments or 2) I lost them.

David Carlisle

@CarLaTeX If I was in Italy there would be no chance of making a 1 O'clock meeting.

Hi TeX friends, I'm using the koma-script scrartcl class and need to reduce the spacing after \maketitle... any quick tricks to do this?

Paulo Cereda

@DavidCarlisle Ma chè!

barbara beeton

5:44 PM

@mickep -- thanks for checking. i'll go with what i've got then.

Paulo Cereda

@barbarabeeton: Quack!

barbara beeton

@PauloCereda -- quack back.

mickep

@barbarabeeton Don't hesitate to ping me if you have a revised edition to read.

barbara beeton

@mickep -- i'll be sure to do that. right now, i'm fighting with the results of years of neglect, and the inability to ask the author about some particularly abstruse definitions. (it was originally written as a dual tex/pdf:html document. can't cope with the latter at this point; just trying to make the tex version correct under current conditions

Harald Hanche-Olsen

@DavidCarlisle All the time. I assume you have dedicated a key on your keyboard to make it happen?

mickep

5:53 PM

@barbarabeeton Hm, sounds like a tough job. Hopefully more people will read the updated version, so that it is worth the job.

@DavidCarlisle ^^ RG is asking me if you are the author. :)

David Carlisle

@PauloCereda I am, but don't feed the trolls:-)

Paulo Cereda

@DavidCarlisle ooh :)

David Carlisle

@PauloCereda probably last time I used tex, what's the date?

Paulo Cereda

@DavidCarlisle I clicked YES. :)

@DavidCarlisle 1992

David Carlisle

@PauloCereda sounds about right

Paulo Cereda

6:54 PM

@DavidCarlisle My UK-TUG talk will cheer you up

Joseph Wright

@PauloCereda Remember you don't actually end up in the dungeon ;)

Paulo Cereda

7:16 PM

@JosephWright Or else you all would get flu. :)

Joseph Wright

@PauloCereda Oh, we end up in the dungeon

Paulo Cereda

@JosephWright :)

@JosephWright: But the room is classy!

Joseph Wright

@PauloCereda You've not been there

Paulo Cereda

@JosephWright I saw a photo, I guess.

Joseph Wright

@PauloCereda Probably the other room

Paulo Cereda

7:20 PM

@JosephWright ah

David Carlisle

@PauloCereda classy would not be the word that immediately comes to mind.

Joseph Wright

@DavidCarlisle :)

Stefan Kottwitz

@PauloCereda Wear a classy chimney pot hat, to protect against falling overhead projectors.

Paulo Cereda

@StefanKottwitz ooh

@DavidCarlisle cozy?

Joseph Wright

@StefanKottwitz :)

Stefan Kottwitz

7:22 PM

@DavidCarlisle classy -> classified?

David Carlisle

@StefanKottwitz you've been there, how would you describe it? :-)

Paulo Cereda

Fletcher Room

Available during Term-time & vacation

Description: Semi basement but with four windows across two walls onto lightwell.

Facilities: Ceiling-mounted data projector. Full wireless and broadband internet access. Screen, flip chart and white board. Fabric seated and backed chairs.

Accessibility: Down stairs, no lift.

Joseph Wright

@PauloCereda That's a very flattering photo

Stefan Kottwitz

@DavidCarlisle It's perfect for a darknet LAN party.

Paulo Cereda

@JosephWright looks better than the Dolphin Yard Teaching Room

We could get this one:

There's eleven types of knives, forks and spoons. I have no idea of their usage. :)

Joseph Wright

7:26 PM

@PauloCereda If we ever run a 'proper' meeting that's more-or-less my plan

David Carlisle

@PauloCereda here's a better photo (picture of a vim user)

tripadvisor.co.uk/…

Paulo Cereda

@JosephWright ooh I am gonna buy a top hat and a monocle just to be there. :)

@DavidCarlisle LOL

@DavidCarlisle Speaking of vim, you are going to love my talk

Joseph Wright

@TeXnician I mean UK-TUG, not the team

TeXnician

@JosephWright Oh, right, if you can introduce l3 then :)

Paulo Cereda

we can also play cricket in the garden:

David Carlisle

7:29 PM

@PauloCereda don't even think of walking on the grass of a college lawn

yo'

@PauloCereda that's crocket you play in gardens!

Paulo Cereda

@DavidCarlisle but... I am a duck, I am supposed to walk on the grass!

Joseph Wright

@TeXnician Working on it

Paulo Cereda

@yo' ooh

TeXnician

@JosephWright Btw: Is there an actual roadmap (I mean with real dates next to the milestones) for releasing l3 (have never seen such thing).

yo'

7:32 PM

@TeXnician yes, it's called "David, Joseph and Frank stuck in a traffic jam"

Paulo Cereda

@TeXnician according to David, the roadmap should not consist of walking on the grass. :)

@yo' ooh next year we will have a joke-like sketch.

"Two English, Three German, a Brazilian and a Italian enter in a bar..."

TeXnician

@yo' Well, I guess not that kind of roads...

yo'

@PauloCereda an Italian :-)

TeXnician

@PauloCereda "... how many ducks are swimming on their cocktails?"

Paulo Cereda

@TeXnician ooh it's on my bill

@yo' Das Italien. :)

Joseph Wright

7:34 PM

@TeXnician Short answer: no

Paulo Cereda

@JosephWright Long answer: nooooooooooooooooooooooooooooooooo

:)

yo'

@PauloCereda :)

Joseph Wright

@PauloCereda :)

Paulo Cereda

@JosephWright Frank would kill me. :)

Joseph Wright

@yo' More 'Frank et al. think 'Why did we let this annoying so-and-so join the team?''

@TeXnician We need to sort 'style sheets', plus there is 2e work to do (and lately to actually improve the kernel)

Paulo Cereda

7:44 PM

@JosephWright: ooh let's get this one: The Mackesy Room

Pembroke College

David Carlisle

@PauloCereda google.co.uk/…

Paulo Cereda

@DavidCarlisle oh

Joseph Wright

@PauloCereda We use Trinity as we knew they had a room some years ago, and they are pretty cheap (Oxford is convenient for various people)

Paulo Cereda

@JosephWright ah!

yo'

fruit flies drink my Porto :-(

Paulo Cereda

7:54 PM

@yo' oh no

barbara beeton

8:18 PM

@PauloCereda -- oh, my goodness, that looks very nice! (i attended pembroke college, but not that one.)

Paulo Cereda

@barbarabeeton :)

barbara beeton

8:43 PM

@mickep (and anyone else interested in the "short math guide") -- in section 4.9, boxed formulas, i have a method for boxing an entire equation including equation number; also, the faq referred to no longer exists. should i (1) include the instructions (no extra package), or (2) suggest looking into another package (such as framed), or (3) disrecommend it as bad style?

another "short math guide" question ... i'm having a real problem integrating hyperref. would it be preferable to (1) just get the content in good order and release a draft, or (2) wait to release until i've conquered the hyperref problems?

David Carlisle

9:23 PM

@barbarabeeton I could probably look at hyperref

barbara beeton

@DavidCarlisle -- thanks! let me get the content to the point where it doesn't crash, and i'll send it along. most likely by the end of the week.

egreg

10:18 PM

@yo' Time flies like an arrow. Fruit flies like a banana. (G. Marx)

barbara beeton

a couple more "short math guide" questions. in section 3.18, "math font switches:, most of the \math... font styles are shown in a table, but not \mathrm or \mathscr (which requires another font). should they be? and if so, what font should be used to show \mathscr (the two obvious candidates are euler and 'rsfs')?

David Carlisle

10:40 PM

@barbarabeeton rsfs is nicer but euler's more "AMS" isn't it?

yo'

11:26 PM

@egreg oh my English!

Alan Munn

@yo' :)
