How do you just create a new page in Context? (Sorry if this is a stupid question, but I can't seem to find this anywhere. I found \blank, but it doesn't take anything relevant to making a new page as far as I can tell.)

12:37 AM

@bb010g \page? (I don't know ConTeXt) wiki.contextgarden.net/Command/page

@Canageek Surely not. 'metre' and 'litre' (and 'theatre'). The basic rule AFAIK is British spellings for all the 'our' and 're' words and American spelling for all the 'ize' words. Plus 'ce' vs 'se' for nouns/verbs (British), also doubled 'l' for words ending in 'l' which have suffixes: 'cancelled' and 'travelling'. Also there's an Oxford Canadian dictionary which I bet SFU has online access to.

@AlanMunn There is an Oxford Canadian: It is pretty useless. It misses a lot of words, and doesn't have nearly the useful bits of the OED.

@AlanMunn And I'm aware it would make sense. Just asked two people in my lab. One spells both er, the other spells it meter and litre.

And the one who spells both the same way says he switched once he started reading a bunch of American papers

@Canageek probably best to stick to Canadian French:-)

12:53 AM

@Canageek Ok, I've never used used it. I think that the influence of American English is hard to overcome in Canada, especially in writing science. I make an effort to maintain Canadian spellings in my own writing, since I'm in the US. :)

@Canageek Speaking of spelling, 'than' is the spelling used in the comparative, i.e., 'taller than' (not 'then', which is used for temporal meanings and 'if ... then'.) This of course is not a Canadian thing...

@DavidCarlisle Just as long as you don't say it out loud (according to the Parisians).

1:47 AM

@AlanMunn Yeah, that's it. \page[yes]. I don't know how I missed it. ._.

5 hours later…

6:47 AM

@AlanMunn No, that is me making a mistake ;)

1 hour later…

7:57 AM

@AlanMunn Also, the unit of distance is 'metre' everywhere in technical writing (in the same way I have to put up with 'sulfur' when writing journal articles even if using UK English spelling)

1 hour later…

9:25 AM

@egreg Can you stop making out with the users for points ? It's unethical :D

Thanks a lot dear.... — Shahnawaz Ahmad 2 hours ago

@percusse Language barrier

@percusse LOL

@percusse, @egreg: This reminds of Captain Kevin Darling from Blackadder (@JosephWright). His surname surely caused him some embarassing moments. :) What's the matter with you, Darling?

@PauloCereda Or the character interpreted by Kareem Abdul-Jabbar in "Airplane!": his name is Roger Murdock and, whenever Capt. Clarence Oveur answers "ROGER" to the control, he turns to him saying "Uh?"

@egreg oooh :)

@egreg: in other news, today is a holiday for us, it's our patron saint. :)

9:40 AM

Don't Call Me Shirley - Airplane! (9/10) Movie CLIP (1980) HD

@percusse ooh :)

11:13 AM

@GuilhermeZ.Santos @PauloCereda You'll be happy to know I added an abnt tag.

@GuilhermeZ.Santos @PauloCereda My gift for the feast of Nossa Senhora de Aparecida

@PauloCereda It's also the anniversary of a sorrowful event.

Guilherme Z. Santos

11:40 AM

@egreg awesome! Let's have some fun then, ;D

I'll retag the remaining abnt involving questions in Batches as suggested by @yo'

11:59 AM

@GuilhermeZ.Santos @JosephWright shall be able to deal with it without bumping the question by a tag rename...

Hi @yo'

@Danu heyyo!

I've got a question about shortcuts

It's mostly an opinion-type one so not something for the main site

I'm typing up a lot of mathematics nowadays, and I'd like to have some nice shortcuts for [theorem, corollary, lemma, proposition, definition, example] (maybe one or two more)

But I'm not sure what would be nice shortcuts---do you have any opinion?

I tried using Alt+[letter]

@yo' There are not so many of them; if @GuilhermeZ.Santos does, say, five a day, there should be no big problem with bumping up.

but it doesn't work properly because Alt switches you to the menu of a program, usually

so things like Alt+E bring me to the "edit" tab in texstudio, instead of working like a shortcut inside the document I'm typing

12:06 PM

@egreg I'd say 15 is still fine

@Danu shortcuts where? in some editor?

Yeah

@Danu (sorry for the delay, when you don't ping me, I don't notice). Well, I don't use any shortcuts in the text editor but the ones for save, compile, close.

@yo' Oh, really? Hmm...

You must be a quick typer.

@Danu ummmm, even for editing other people's work, it's not worth it. What I use for converting documents from M$ W@#$ to LaTeX is things like \EQ{5}{E=mc^2} or \Fig{3}{Plot of XYZ.}, but there are more reasons for that than just getting quicker.

12:30 PM

Okay.

Guilherme Z. Santos

@yo' @egreg we can settle at 10, that's 5 days to get all 50 of them.

@PauloCereda To relieve you from thinking too much about the sorrowful anniversary, I'll tell you that Cristoforo Colombo has nothing to do with it.

@GuilhermeZ.Santos tex.stackexchange.com/search?q=abntex2 lists 71, but it's not a big deal either.

Guilherme Z. Santos

@egreg oh well, weird, I would think that searching for "abnt" would bring the most results. How is it that works this SX search engines??

@GuilhermeZ.Santos I've not yet understood well how they work

Guilherme Z. Santos

12:48 PM

@egreg Indeed mysterious!

^ can someone test this for me Overleaf is reeeeally slow today... (I'm at work so, no TeXing here... :( )

@egreg are you referring to tex macros?

@DavidCarlisle Yeah, sure! :P

1:04 PM

@GuilhermeZ.Santos is this a trick dos attack:-) it's taking forever.....

Guilherme Z. Santos

@DavidCarlisle Hahaha, no. I just found the Problem!! thank's David!

@DavidCarlisle I changed the Definition of Domain but not made the Change to the sampling rate so it was sampling like banana crazy monkey!

Dec 15 '14 at 10:45, by David Carlisle

doesn't inspire me with confidence, I think I'll stick with picture mode: http://tex.stackexchange.com/questions/218030/there-is-no-p-in-font-nullfont-whe‌n-drawing-arrow

Guilherme Z. Santos

@DavidCarlisle I dot not get the reference, at all. Hahah (also I'd set Overleaf to LuaTeX and forgot to change it back, that was also slowing it down, pardon my stupidity)

Still, is there something wrong here I'm not seeing? The red spiral is normally obbeying the command, but the blue one has a weird end radius... @DavidCarlisle this is no trick attack, i promise! :D

@GuilhermeZ.Santos oh I just respond to all tikz questions by saying you should use standard latex \begin{picture} instead.

Guilherme Z. Santos

1:21 PM

@DavidCarlisle tikz is amazing! what is that Picture environment?? never seen it before...

It was suggested in chat http://chat.stackexchange.com/transcript/message/9482087#9482087 That picture mode would be the ideal tool for the job here: \documentclass{article} \begin{document} \begin{picture}(200,100) \put(30,40){\line(1,0){150}} \put(30,40){\line(0,1){60}} \put(30,100){\line(...

Guilherme Z. Santos

@DavidCarlisle LOL... but seriously though, are you trying to get me fired??? I was not able to contain myself with this one, people are staring at me now...

Guilherme Z. Santos

1:52 PM

Ok, no need for help on the previous code, already found out what's wrong and fixed it! =D

1 hour later…

3:17 PM

@DavidCarlisle Working on LuaTeX v1.0 testing. Could you look at e.g. tlb0027a? There seem to be some kerns that have gone 'walkabout'

@DavidCarlisle Haven't got through everything, but if I remove the new discretionary logging, I find at least tlb0014 tlb0027a tlb0027b tlb0028 tlb0049 tlb0057-2015 tlb0057 tlb0150 tlb0152 tlb0427 tlb0574 tlb1135 seem to show the same

3:29 PM

@JosephWright Ok, I'll rebuild l3build and try again

@DavidCarlisle -- yesterday i sent you mail about an amsmath question. have you read it yet?

@barbarabeeton half read it, will reply at some point:-)

@DavidCarlisle -- thanks. i have some further thoughts that i didn't put in the mail.

@JosephWright The kern gets pushed into the discretionary log (which is OK I think) although more work to normalise, compare

\tracingonline1
\showboxbreadth100
\showboxdepth100

\setbox0=\hbox{Contents}\showbox0

\bye

.\tenrm C
.\tenrm o
.\tenrm n
.\kern-0.27779
.\tenrm t
.\tenrm e
.\tenrm n
.\kern-0.27779
.\tenrm t
.\tenrm s

@JosephWright ^^^ with pdftex and vvv with luatex

.\tenrm C
.\tenrm o
.\tenrm n
.\discretionary (penalty 50)
..< \tenrm -
..= \kern-0.27779
.\tenrm t
.\tenrm e
.\tenrm n
.\kern-0.27779
.\tenrm t
.\tenrm s

@JosephWright if the discretionary isn't taken then you need to use the ...= lines but bring them up one level so lose a .=<space> from the initial string of dots

4:02 PM

@DavidCarlisle Ah, OK, I'd not traced it all of the way through (just looked at the diffs). I'm not sure you can normalise this: depends on knowing what is happening in both files ...

@JosephWright in general tricky but ..= \kern<nospace>length will always be an implicit kern in a discretionary not taken and (probably) you can always just expose that as a normal implicit kern, although I suppose if that point was considered as a break point classic tex would show the discretionary (I can't remember when exactly it does that:-) anyway it would get the number of failures down, and just add luatex.tlg for the rest?

@DavidCarlisle I'll see if i can come up with a logic that works

@DavidCarlisle There are a small number I still want to review

@DavidCarlisle Can't check anything in in terms of new .luatex.tlg files yet unless we accept it's just thee and me doing any testing ...

@JosephWright I accept that.

4:17 PM

@DavidCarlisle :)

@JosephWright realistically it's us and Frank and Frank's mostly windows so could use same pre-built version that you have if he wanted to run the tests.

@DavidCarlisle He's bought a Mac I think ...

@JosephWright it's probably got a windows vm on it somewhere;-)

@DavidCarlisle Likely: that's what I do for testing on my own machine (here at work it's Windows-only)

2 hours later…

6:26 PM

@JosephWright: talk is being uploaded, link will arrive soon. :)

@PauloCereda Cool

6:49 PM

@DavidCarlisle If I ignore for the moment the test files that already need a .luatex.tlg, I'm down to 11 now. One is an easy fix, the others may need a little more work.

@JosephWright sounds good, do you think they are all OK (so could be normalised away or have luatex.tlg?

@DavidCarlisle I'm working through them

@JosephWright Ok ping me if there's any you want me to look at

@DavidCarlisle WATCH MY TALK

^^ ping

@PauloCereda would spoil the surprise for saturday

6:51 PM

@DavidCarlisle :)

@DavidCarlisle ooh

@DavidCarlisle tlb0435 is odd

@JosephWright: you got mail. :)

@JosephWright oh that one:-) hand on will run again see what it's doing now

@PauloCereda Looks OK

6:59 PM

@JosephWright Cool.

@JosephWright the box here doesn't suppress hyphenation but I'm not sure if that's by design:

This is a supercalifragilisticexpialidocious%
 \hbox to 1em{}
 sentence.

@DavidCarlisle Looks like they've dropped \glue(\belowdisplayskip) 0.0 from the log (tlb0881)

@DavidCarlisle Question to the list?

@JosephWright oh I thought that was potentially useful info.

@DavidCarlisle I'll ask about it

@JosephWright I bet it get the standard "we don't promise to be compatible" reply;-)

7:06 PM

@DavidCarlisle Likely

7:32 PM

@DavidCarlisle Regarding compability they change the fontloader and it no longer works with luaotfload ;-( github.com/lualatex/luaotfload/issues/385

@UlrikeFischer yes I saw that mail :(

@UlrikeFischer do you use that config normally or were you specifically testing it?

@DavidCarlisle I use it when trying to debug something. In this case I was looking at tex.stackexchange.com/questions/333510/….

@UlrikeFischer ah

8:02 PM

@DavidCarlisle I'm collecting up the oddities to ask on the LuaTeX list. I've got another checkin coming up: probably will need no more than a handful of new .luatex.tlg files in the end :)

2 hours later…

9:54 PM

@PauloCereda Brazilians can learn a Yorkshire accent (useful for Monty Python sketches:-) bbc.co.uk/news/uk-england-york-north-yorkshire-37628608

10:30 PM

@DavidCarlisle ooh :) For a minute, I thought @JosephWright sent you my video. There's a Yorkshire mention!

@egreg will love my answer to Yannis' question.

10:48 PM

No, they won't. :P — egreg 2 mins ago

@DavidCarlisle ^^^^^ Anathema!

11:00 PM

@egreg it's literally not readable, but you get what you ask for:(
