Is there a simple way to include brief code snippits similar to the code here of markdown?

@Scuzzball In what context?

@JosephWright I don't really know. I'm at that point in learning latex that I don't really know what I need to learn. I ended up using ( stuff ), which isn't really what I wanted but it worked. What I actually want is to be able to mark a phrase to be mono-spaced, and have a different background colour. I'm betting there is some style thing I can define for that?

@Scuzzball For example tex.stackexchange.com/questions/39276/…: you want a verbatim environment with a coloured background

@DavidCarlisle, @PauloCereda Cache all working :-)

@WillRobertson fontspec and unicode-math tests added: they might need to be a bit more sophisticated as I've really done very little!

Turns out we need about 75Mb of compressed space for a TL set up

@JosephWright Typo in interface3.pdf: in the description of \char_generate:nn the final <catcode> should be <charcode>.

@egreg Fixed in the SVN, thanks

@egreg We'll be changing the implementation shortly :-)

Hello @WillRobertson

@JosephWright Generally the problems we've had have literally been from things breaking on package load or first font load, so I don't think we need to go much further…

@JosephWright Hello briefly :)

@JosephWright Nice work with the CI setup!!

@WillRobertson That's my hope too

@WillRobertson I'm going to write up some notes for TUGboat: I think it's generally useful

@WillRobertson Surprisingly easy, when you consider TeX isn't on the 'usual suspects' list

@WillRobertson OK, so my quick tests probably cover it then, at least at present

@WillRobertson I might add a fontspec test for a non-existent font to force the code down that path

@JosephWright I'm not sure if that's necessary — it calls a TeX error anyway, so what would you expect to "break" in that instance?

@WillRobertson OK, if it's not that useful I won't bother :-)

@JosephWright, @WillRobertson see the luaotfload file permissions thing? How come it's changing the permissions? (I could look later but wondered if you had already:-)

@DavidCarlisle Not my area of responsibility :) I'm swamped at the moment before heading on another plane trip tomorrow — sorry haven't looked

@JosephWright I see you have changed \c_job_name_tl

@JosephWright Awesome!

Morning @FrankMittelbach

@DavidCarlisle morning ... fighting my desktop

@FrankMittelbach the mac?

@DavidCarlisle nope the windows one ... it doesn't stay hiberated any more

or did ... maybe I got it working again

@JosephWright oops, thought I'd look at that permissions thing and hit a bug,

\input luaotfload.sty

Hello

! Undefined control sequence.
l.143 ...ng anonymous user whatsit no. \@percentchar

@JosephWright just define \@percentchar for plain? or use some inline catcode trickery to avoid assuming an existing definition? (defining \@percentchar seems best to me)

@egreg Yes

@DavidCarlisle Odd, isn't it!

@JosephWright Editing my answers where it appears.

@egreg OK: I think I need to send a notice to LaTeX-L about that one

@DavidCarlisle Where's that coming from?

@JosephWright generating a %s in whatsit logging

El Capitan arrives today.

@JosephWright: warning("defining anonymous user whatsit no. \@percentchar seems our tests in plain are missing some things...

@DavidCarlisle Ah

@DavidCarlisle Yes, I guess add a definition then!

@PauloCereda Not round here

@JosephWright probably later on today, I'll report. :)

@JosephWright: ^^ :)

73k steps of the simulation are done. If I only remembered how many steps there are :D Ah it's 112k, not too bad.

I insterted an image into my document, and set centering, but the image is centered along the edge, rather than the center of the image. how can I center the image in relation to the center of the image being aligned with the center of the document?

@Johannes_B No, why? This is the example of bad OP and requests. I leave them as a roadmap to user hell :-P

@j0h What you want is the default behaviour, unless the image is wider than \textwidth, in which case it will stick out in the right margin.

@egreg: Thanks for editing the vector answer -- I will omit the braces then in future

@j0h You know where you get the best help.

@yo' : tex.stackexchange.com/questions/270358/how-do-i-center-an-image :D

@ChristianHupfer You're welcome!

@egreg: expl3 is quite cool but still very new to me

@ChristianHupfer One learns only by doing.

@egreg Or by making mistakes ;-)

@ChristianHupfer That's part of the “doing” concept, of course!

@egreg Well, English has a nice idiom for it: Practice makes perfect :)

@egreg 90 % of doing is making mistakes, at least for me...

@yo' Osgood Fielding III would answer “nobody's perfect!”

I finished reading a book called Dictionary. The zebra was the murderer! :)

@yo' You know who is Osgood Fielding III, don't you?

@egreg I wouldn't remember (I know the movie in Czech), but of course I know the movie :-)

@JosephWright, @ChristianHupfer: ^^ this is from a published paper of mine. There's a lot of MP references all over the text. :)

@PauloCereda I am missing spam spam spam

@PauloCereda someone's wanna be funny? :)

@yo' This is super cereal. :)

@ChristianHupfer Since it's a set, you cannot admit duplicate elements. :)

@PauloCereda Pah, that's too much Math :D

The same issue with caption package, I assume? We had some of this questions in the last days

@PauloCereda when you look up "Cereda" and you find an article with 1313 authors (probably not yours though...)

@yo' ooh a cosmic ray conference!

@PauloCereda I read this is super cereda for one moment :D

It's pew pew pew all over the place!

@ChristianHupfer LOL

@yo' If ever a code is broken or code is to be repaired .... call Super Cereda and his Arara Squad ;-) @PauloCereda

@PauloCereda -- if they decide to extend their naming scheme to u.s. national parks outside of california, i nominate a mountain in the tetons: disappointment peak.

@barbarabeeton :)

@barbarabeeton that would be very positive. Whatever comes after a disappointment peak is better, says the optimist. :)

Hello, I have a problem with \systeme. If the left side of equation is (1-5)X=... it decides to print -5)X+(1=.... . And by the way is aligning system of equations is better practice than not to?

Genuinity has a name.

@user2941942 Could you make an example?

simple one

It probably has something to do with brackets ( ). I read the manual for this (which is in french). And didn't see one example with brackets.

@user2941942 No, it has to do with the fact that + and - are taken as delimiters; just hide the ones that don't separate variables in braces: \systeme*{{(1-5)}x=5y+6z,{(5-7)}z=10x}

@egreg thanks. :)

@user2941942 You're always welcome!

@DavidRobertson Hi! Are you expert in cricket? Otherwise this is not your place. ;-)

@egreg Oh hi! I was just being nosey. I've used TeX.SE ages as an anonymous searcher, and thought it was time to give back a little :) As for cricket, I'm afraid I'm extremely ignorant!

@DavidRobertson You did well. A Briton can't be ignorant about cricket! We talk about it all the time! I consider myself an expert: I know that you can be in or out, for instance. :)

@egreg My father tried to encourage me to like cricket as I was growing up, so I know some of the words. Wide, beamer, yorkie, leg, lbw, silly mid-off... They don't make it easy to learn this stuff!

@DavidRobertson :)

@egreg We need to summon the other David and Nicola. :)

@JosephWright — FWIW, I've now added a fork of xunicode to fontspec (called fontspec-xunicode.sty) that starts to approach a minimal version of Ross's xunicode. This removes graphicx dependencies, etc. However, it requires filehook to retain compatibility with xunicode for its (presumably few) users.

@JosephWright — Probably very sensible to strip out the xunicode fork even more; it contains 2000 lines of presumably seldom-used csnames for accessing symbols and accented letters. To be honest, I think it needs to contain little more than base LaTeX+textcomp symbols.

@PauloCereda @DavidCarlisle, a fellow Briton needs your help!

@JosephWright — P.S. I shouldn't have stayed up so late looking at this :)

@WillRobertson :-)

@JosephWright I'll be offline / limited connectivity for the next week; can resume later next week.

@WillRobertson Cool: there's the format update for me to worry about starting tomorrow (or rather starting tonight when I get all of the zip files ready)

@WillRobertson We now have a proper testing set up at least :-)

@JosephWright Good luck :) And good night!

@WillRobertson night, Will!

@egreg what?

@JosephWright I'll try not to find any more bugs this evening:-)

@DavidRobertson It's OK they are all ignorant here, it is easy to bluff your way through and impress those from non cricket playing countries.

@DavidCarlisle VVVV

@egreg yes found it:-)

for those who wish to become conversant with how cricket is played, i highly recommend goodreads.com/book/show/662051.What_Is_a_Googly_ after reading this book, i have been able to follow and enjoy "local" matches played on the fields of bermuda by both school children and more mature participants.

@barbarabeeton ooh cool! :) And we can use this afterwards: theoval.cmp.uea.ac.uk/~nlct/latex/packages/crkscrsh :)

@DavidCarlisle groups.google.com/d/msg/comp.text.tex/lOq_jtRRGZk/ZmZPlrjXBwAJ

@JosephWright lets see what tomorrow brings....

Lost the train I wanted to catch because of a traffic jam. :( But now I'm the later train with my glass of wine in front of me. :)

@egreg You deserve another glass of wine. :)

@DavidCarlisle Tests all pass here

@JosephWright it's the things we don't test for that worry me:-)

@DavidCarlisle :-|

@DavidCarlisle Are you OK if I add Elié et al. to the luatexbase copyright line (for earlier years): we have after all taken bits of their code

@JosephWright good plan

@DavidCarlisle Building everything now

@JosephWright I'm running etex/xetex/luatex check in base:-)

@JosephWright at some point we should convert some of those "examples" in the ltluatexsupp area to l3build tests, although mostly the current ones were just checking documents load at all rather than testing anything specific.

@DavidCarlisle Yup

@DavidCarlisle First we probably need to decide to add LuaTeX to the base test set

@JosephWright possibly not yet, but we could have tests in ltluatexsupp that are effectively testing ltluatex rather than either of the "contrib" packages

@DavidCarlisle Yes

@DavidCarlisle Will you do the SVN branching? (And presumably remove the current branch)

@DavidCarlisle Or perhaps it won't be needed ....

@JosephWright I can yes, (not sure what you mean by remove current branch though)

@DavidCarlisle I assume we only need two branches at any time: current release, development

@JosephWright history is history:-). There isn't a lot to be gained by svn removing a branch, it is still in svn and can be checked out, but I guessed afterwards that's what you meant, I thought initially by "current branch" you meant trunk:-)

@JosephWright all (non luatex) tests pass here

@DavidCarlisle Same here

@DavidCarlisle Plan to send to CTAN tonight

@PauloCereda Goal!

@egreg 500!

For Ronaldo too. :)

@egreg: Morata yay! :)

@PauloCereda 500? are you watching football or cricket?

@DavidCarlisle Ronaldo also scored his 500th goal. :)

@DavidCarlisle For no loss?!

@PauloCereda who's he?

@DavidCarlisle Some Portuguese bloke.

@PauloCereda I didn't know they played cricket in Portugal.

@DavidCarlisle It's football. :)

@PauloCereda oh yes of course it's the rugby football world cup at the moment isn't it. Is Portugal winning?

@DavidCarlisle Uh-oh. :)

@JosephWright thanks:-)

@DavidCarlisle Submission off to CTAN

@JosephWright yeh! Sounds good, I guess it hits tl on Friday mostly....

@PauloCereda Actually he's from an island in the middle of nowhere.

@DavidCarlisle Yup

@DavidCarlisle Everything now sent (just done ctablestack)

@JosephWright don't change it now but having build.lua executable was intentional it allows the first line of #!/usr/bin/env texlua to do something useful

@JosephWright I thought I'd copied that from you?

@DavidCarlisle Probably a Windows USB stick thing

@DavidCarlisle First lines there for sh ...

@DavidCarlisle I'm always surprised version control systems check in these attributes anyway: they are really local things

@JosephWright but if you are going to use an explicit interpreter may as well use texlua rather than sh, by making it executable you can just do ./build.lua check and it does the right thing because of the #!

@JosephWright not if you want someone to check out the sources and type make things have to be executable or writable from the start.

@DavidCarlisle make is not something you have in the version control, though: you have a Maketfile :-)

@JosephWright yes but the scripts Makefile calls typically need to be executable.

@JosephWright another suppressfontnotfounderror report, does no one look at the archives before reporting a bug:(

@DavidCarlisle Where?

@DavidCarlisle Ah, I see

@DavidCarlisle Perhaps: won't work so well on Windows ;-)

@JosephWright windows without cygwin is not something I care to contemplate

@DavidCarlisle I know

@DavidCarlisle I guess I see the #! ... line as akin to a DTD statement in an HTML file: part of a 'properly-formed' script (and almost as important as MZ at the start of a Windows binary)

@JosephWright yes but the usual use is so that you just use the command by name without executing the interpreter first.

@DavidCarlisle Like I say, doesn't work on Windows :-)

@JosephWright let me just check which OS I am on... :-)

@PauloCereda Gooooal!!!

@egreg 501?

No, 2

@egreg Complicated scoring system football. I clearly don't understand.

@egreg Zaza!

@DavidCarlisle Ronaldo scored, now it's 501. :)

@PauloCereda I wish you and @egreg would agree on the rules of the game, it's too confusing getting conflicting accounts.

@DavidCarlisle Perhaps 501 for 2?

@DavidCarlisle We are watching two games at once. :)

@JosephWright quite a good score, especially for Portugal which isn't noted for cricket. I wonder who they are playing?

@DavidCarlisle Pretty dry down there: flat track probably

@JosephWright Paulo was apparently also watching an irrelevant match. I was watching the really important one.

@egreg I was watching both. :)

@JosephWright @barbarabeeton suggested that I ping you about a question which we think should have been closed as a duplicate rather than as unclear. At least, it would be useful as a duplicate, whereas it isn't very useful as unclear. (Note that the question and discussion was sufficiently clear for the OP's problem to be solved.) Ref.: tex.stackexchange.com/questions/183861/…. Would you consider modifying it to link appropriately?
