@PauloCereda Hi Paulo, could you please send me a link to your Fedora post install guide?

wget

Hi guys. This doesn't require a dedicated question for that. I'm trying to specify some text inside my lstlisting to be bold. Is this the right syntax when passing this as an argument to the \begin statement?
\begin{lstlisting}{morecomment=[s][keywordstyle]{/*}{*/}}

This doesn't seem to be working. and I need to use \lstset instead, which isn't what I want. I want my changes to be local to that lstlisting env.

Any idea welcome.

According to that page tex.stackexchange.com/a/180223/66964 I should use [ ] instead of brackets, but the document isn't compiling with these nested square brackets.

David Carlisle

@wget that's a faq, for any latex optional argument you need [{...[..]...}] to hide nested []

wget

@DavidCarlisle Unfortunately \begin{lstlisting}[{morecomment=[s][keywordstyle]{/*}{*/}}]
isn't working

I meant the document isn't compiling.

David Carlisle

@wget well make a proper example and post the exact error message as a question on site;-)

Paulo Cereda

09:25

@michal.h21 Sure! :) github.com/cereda/f21-setup

michal.h21

@PauloCereda thanks. I tried to upgrade my Ubuntu 10.10 in work and it didn't work well :(

Paulo Cereda

@michal.h21 Ouch, sorry to hear. It's been a while since I saw a Ubuntu system.

@michal.h21: is it me or Ubuntu is losing space nowadays?

michal.h21

@PauloCereda it was really old and I didn't want to touch it as long as it worked, but it had really old Firefox and lot of pages stopped to work

Paulo Cereda

@michal.h21 Oh no.

michal.h21

@PauloCereda it probably is, I was originally using mint and it transformed to Ubuntu somehow after some upgrade :D

Paulo Cereda

09:33

@michal.h21 :) I once had Mint in an old netbook. It was quite interesting.

wget

@DavidCarlisle Done. tex.stackexchange.com/questions/236125/…

michal.h21

@PauloCereda I installed Mint on my colleague's laptop and she likes it. but I really like Gnome Shell, so I am happy that I have Fedora even in work now

Paulo Cereda

@michal.h21 Cool. :) By the way, F22 is now in alpha. :)

michal.h21

@PauloCereda so new upgrade soon? oh noo :(

Paulo Cereda

@michal.h21 No worries. :)

I'm excited with the new integrated notification system.

michal.h21

09:41

@PauloCereda yeah, it looks really pretty

btw, I probably will not go to Darmstadt

Paulo Cereda

@michal.h21 oh :(

moose

Hi Paulo

michal.h21

@PauloCereda but I was asked to have a presentation about tex4ebook at conference about open source software in education in Slovakia,

moose

(and hello to everybody else, of course)

Paulo Cereda

@moose Hello! :)

@michal.h21 Skype then?

michal.h21

09:54

@PauloCereda no, it should be some main presentation for about 1.5 hour. which will be quite interesting given that I never had any public speech for more than 4 people and there should be about 50 of them

Paulo Cereda

@michal.h21 ooh cool!

michal.h21

@PauloCereda and I should write three articles for CSTUG bulletin and one for the conference and it all only because I posted one mail to CSTUG mailing list :(

Paulo Cereda

@michal.h21 And one for TUGBoat too! @barbarabeeton: poke Michal Hoftich for an article. :)

moose

@PauloCereda Are you aware of any place where I can ask typesetting questions (not necessarily related to TeX)? (e.g. I currently have a question about representation of single-line formulas)

Paulo Cereda

@moose hm good question. Perhaps in one of the math-related SE chatrooms?

michal.h21

10:08

@PauloCereda sure, articles in English, do you want to kill me? :D

Paulo Cereda

@michal.h21 <3

michal.h21

btw I am after many years close to have my blogging system based on tex4ht finished:

Regarding the question I asked about one hour ago, and for which I already got an answer (thanks, you really rocks!), http://tex.stackexchange.com/questions/236125/specify-delimiters-in-lstlisting-to-get-some-text-in-bold

do you know how I can have bolder fonts? I already asked this as a sub-question, but didn't get an answer since this is against StackExchange usage rules. Is changing the font the de facto solution to get bolder monospace font?

Paulo Cereda

10:53

What the duck?

arara has now a --preamble option. :)

David Carlisle

@wget one or two font families have bold in two weights (light and normal, or normal and heavy) but most don't.

@PauloCereda we got a new computer (raspberry pi) and guess what I found (and didn't find) in the default install:(

Paulo Cereda

@DavidCarlisle Yay vim! <3

David Carlisle

@PauloCereda ls in /usr/bin showed vi but it's probably vim really:(

Paulo Cereda

@DavidCarlisle At least you know how to quit the application.

:)

David Carlisle

@PauloCereda no, I forgot, but anyway it also came with a bag of plastic cogs and half a million screws so we can do this

@DavidCarlisle If you have any font recommendation, I'm open ;-)

@AlanMunn I have a strange question which you might help me. I am writing a technical toolbox in Python and I have two functions that I have to name. One of them converts a dynamical system model from representing in continuous time to discrete time and vice versa. The traditional way of naming these functions are c2d and d2c and it feels like slang. So I said OK let's call one of them discretize but I don't know what to call the other continutize?! Do you have any suggestions?

Is there any antonym for discretizing or sampling at perodic times ?

It doesn't have to be technical anyways, I'm open for all pair suggestions that would serve the purpose.

12:26

@PauloCereda Did you figure out what StackEgg is? I played it for a couple of minutes, but I didn't get it. It looks like a game, but it isn't fun and I can't see how it helps the site. (Probably an easter egg?)

Paulo Cereda

@moose No idea, to be honest. :)

Paul Gessler

Well somebody (other than me) is clicking buttons there! :-) We're getting close to "graduation" :-D

Yay! We did it!

Paulo Cereda

@PaulGessler What's going on?! :)

Paul Gessler

@PauloCereda oooo so many downvoters, this is out-of-character for TeX.SX! ;-)

How on earth do we get traffic?

This game seems rigged. :-p

Paulo Cereda

@PaulGessler RIP in peace. :P

Paul Gessler

12:36

Need to go for now, good luck with the egg-hatching everyone! :-)

michal.h21

@PauloCereda do you know how to solve issue in tmux, I want to display running process as window name, but my username and path is displayed instead, which is pretty distracting. I fixed it somehow on my laptop, but don't remember how, it is not in .bashrc or .tmux.conf

Paulo Cereda

@michal.h21 No, but I'll investigate. :)

egreg

@moose What day is tomorrow?

Joseph Wright

@PaulGessler Huh?

Paul Gessler

@JosephWright tex.stackexchange.com/stackegg/leaderboard

@JosephWright see also StackEgg ad on the right of main (can't find a way to direct link, sorry)

Joseph Wright

12:50

@PaulGessler I'd seen that: no idea what it is!

@PaulGessler Just seems to want you to say you should answer questions: don't see the point!

Paul Gessler

@JosephWright April Fool's gamification: we're building a fictional version of our site from the ground up. You can read more details in the help link.

Johannes_B

@JosephWright Is that spam? Both other posts seems to be ok. latex-community.org/forum/…

Paul Gessler

Of course the Game Dev site is the first to "win the internet"!

Joseph Wright

@Johannes_B Original post OK, second one spam

Johannes_B

@JosephWright Agreed, but the first 2 posts by the spam-account were non-spam.

@PauloCereda Have worked out what OS tex.ac.uk is running :-)

Paulo Cereda

13:00

@JosephWright ooh do tell. :)

Joseph Wright

@PauloCereda Ubuntu

@PauloCereda Was checking if server got restarted so picked tex.ac.uk/tex-archive/macros/latex/contrib/datetime2 as a test: see bottom of page

Paulo Cereda

@JosephWright Cool. We could edit that string and add something very funny. :)

Joseph Wright

@PauloCereda Probably any Linux distro would work for a 'new' node, I suspect

Paulo Cereda

@JosephWright Yep.

Joseph Wright

@StefanKottwitz As the resident sysadmin, what's the going rate for a hosted server with say 100Gb storage?

@PauloCereda Robin is away for Easter, but once he returns I think there will be some serious discussion

@PauloCereda Would you be willing to help out with running a node?

@PauloCereda I have some experience but not perhaps enough to do it on my own

Paulo Cereda

13:06

@JosephWright I think I can help. :)

Joseph Wright

@PauloCereda Cool

@PauloCereda May have to hold you to that!

Paulo Cereda

@JosephWright Sure. :)

egreg

Is it only me or is the egg business slowing down the site navigation?

Johannes_B

I am simply astonished by how ugly some german post cards are.

Joseph Wright

@egreg Already been commented on on main meta: go to the 'help' in the egg and turn it off entirely

egreg

13:11

@JosephWright Thanks

@JosephWright Still slow.

egreg

@JosephWright And the site went offline for maintenance. ;-)

Paul Gessler

@egreg too many egg-sites incubating for the network to handle. ;-)

Oh no, we are offline!

Now that the site is down, people can develop more TikZ foo. I wonder how long it would take for this question to get a score of ten upvotes, and get answered: latex-community.org/forum/…

Alan Munn

@percusse I can't think of anything that works well (or even half badly, for that matter.) discretize seems clear but continutize isn't a possible word, it would have to be continuize (the 't' belonged to 'discrete' not 'ize'.) But continuize seems awful to me as a word too, and looks weird when spelled. What about make_discrete and make_continuous?

Harish Kumar

Damn! prepared an anwer and just about to click post your answer just to find that site is offline. :(

David Carlisle

@Johannes_B snap:-)

Harish Kumar

@Johannes_B Not without a visual picture to start! Some times you need some kick to start ;)

Johannes_B

@DavidCarlisle Did i mention that i hate cross posting?

@HarishKumar You are welcome to answer as many questions as possible :-) Even non-tikz questions.

Harish Kumar

14:09

@Johannes_B Sure. I will try when I get time. :)

Johannes_B

14:23

What do you guys thin of using the prefix my for new commands and functions and stuff?

Alan Munn

@Johannes_B In example code or real code?

Johannes_B

@AlanMunn Mostly real code, but i know how many people re-use example code.

Alan Munn

@Johannes_B In real code I never do it; I create inscrutable names that I will forget later. ;-) In example code I sometimes do it, but it does have the danger of just being copied. But with example code I think it's useful to distinguish things that are being created brand new in the code from existing macros, so the my prefix helps there.

Johannes_B

@AlanMunn I am using the username or some deviation to mark something new.

Alan Munn

@Johannes_B Yes, that's another way, although I prefer 'my' to that. But that way does presumably encourage people to choose more sensible names when they copy the code.

Johannes_B

14:31

@AlanMunn There was a time when i made annotiations to user code using my initials %JB some comment.

@AlanMunn Last wekk, i recognized one of my comments :-)

@PauloCereda -- thanks for the heads up, paulo. actually, cstug is very good at sending me copies of their bulletin (a very fine publication, by the way), and we have requested translations of quite a few articles from there for (re)publication in tugboat. i'll keep my eyes open -- i suspect michal may not be delighted to be asked to write in english before he has gotten things the way he wants them in czech (at least i assume he'll be writing in czech).

Paulo Cereda

@barbarabeeton My pleasure. :) I suspect @michal likes to be poked. :)

19:46

from ctan-ann i've just received the update notice for the new latex core. i'm intrigued by this part of the announcement: "To facilitate ease-of-use of this new approach, the release date for the kernel has been set to a suitable memorable value." and the date shown is \RequirePackage[2014/05/01]{latexrelease}. so, that's "mayday" ("m'aidez"), unless it's a typo for april 1?

David Carlisle

@barbarabeeton 2014/05/01 is the release date of the previous release

barbara beeton

@DavidCarlisle -- proving once again that i can't read (or read too fast). but then, this implies that w.r.t any updates to packages after that date, all bets are off. i guess i'll just have to find time to read issue 22 of ltnews. (which i assume will be found on a ctan mirror in the /latex/doc area).

@yo' Envy!

yo'

@egreg :-)

Johannes_B

@yo' And you didn't pick me up? Sitting in that smelly library :-(

yo'

@Johannes_B you weren't nearby

David Carlisle

19:58

@barbarabeeton not sure what you mean by "all bets off" basically it works like any document that had been using \usepackage{fixltx2e} has been working for 10 years or so.

Paulo Cereda

@yo' <3 I had to come up with something special for you. :)

Frank Mittelbach

@yo' good concept .. except that it shouldn't go together with staring at your smartphone and typing in chats :-)

Johannes_B

@yo' I am just wondering, you travel by train, right? What is your route?

yo'

@FrankMittelbach We're having a "business" meeting with my scoutmaster colleagues

@Johannes_B by plane of course.

Johannes_B

@yo' Ok, would be hard to get me that way.

Frank Mittelbach

20:00

@yo' whatever the reason ... just saying trinking somehting like this should not go together with electronics

yo'

@FrankMittelbach yeah I know. I just had to share this perfect event!

Frank Mittelbach

@yo' but this is the way the world turns these days

yo'

@FrankMittelbach yeah. But the point is, we really work on the computer. I should actually leave. Laterz

Frank Mittelbach

which means I should probably open a bottle before continuing ...

Johannes_B

@yo' Just checked, Deutsche Bahn would send you over Dresden to Leipzig. Not crossing Freiberg.

Paulo Cereda

20:03

Ein Bier, bitte!

:)

barbara beeton

@DavidCarlisle -- what i meant is that if someone does take the "backout" option (unless i once again misunderstand what i thought i read), then they will either have to continue to use \usepackage{fixltx2e} (which, of course, doesn't make sense; if that's the case, just upgrade), or be prepared for new versions of other packages not to work.

David Carlisle

@barbarabeeton I don't see that at all. If you install a new version of a package it may or may not work on your document, that's always been the case, I don't see anything in this release that changes that.

Joseph Wright

@FrankMittelbach, @DavidCarlisle Karl has mailed me with a few things that need addressing from the upload(s). I'm fixing in the SVN then will e-mail the team and CTAN to get agreement on a second upload and make sure we are clear on the versioning, etc.

Frank Mittelbach

@JosephWright you know that there is a multicol fix waiting? I'm just about to upload that one

David Carlisle

@JosephWright just proves putting it on ctan rather than dropbox good for focussing people to more rigorous testing:-)

Frank Mittelbach

20:08

@DavidCarlisle yeah but the bad thing is that you now have burned a date :-) so we should have a date count down next time

Joseph Wright

@FrankMittelbach That I had not thought of but in any case does mean we'll need a second attempt!

@DavidCarlisle Indeed

@FrankMittelbach I'd hope we can perhaps live with that as no-one is likely to have used this mechanism just yet!

Frank Mittelbach

@JosephWright still not convinced nominal dates are really workable even though they might be memorable - so \fmtversion may be 1 Jan but the package dates should simply reflect the latest date of file change/upload in my opinion

for package read bundle

Joseph Wright

@FrankMittelbach It was only this one that it seemed sensible to have as memorable

Frank Mittelbach

@JosephWright again --- fine for the release date in the kernel ie \fmtversion ... doesn't have to be the bundle date

Joseph Wright

@FrankMittelbach Well as we seem to need to re-upload anyway we can fix that (as you suggested): I'll mail the team probably tomorrow then assuming all OK check with CTAN

David Carlisle

20:25

@FrankMittelbach not necessarily, if we fix specific files, it isn't clear we have to bump the format date is it? Especially if the format hasn't actually changed

@FrankMittelbach Oh OK, yes I'm not so bothered about the ctan package dates, yes just using the last file change date or even the upload date

Sean Allred

Does anyone know of a 'standard' document class that uses expl3? I'm curious to see how some problems are approached.

(Although I suppose that, strictly speaking, this is kind of a bleeding between the designer/programmer role...)

Joseph Wright

@SeanAllred I'd avoid it: \ProvidesExplClass is probably not such a great idea

Sean Allred

@JosephWright Would you rather recommend the modular approach, I assume?

I just don't know how to implement a table of contents without overlap.

(There's a good chance I can get my company to use TeX as the PDF backend for the internal CMS :))

Frank Mittelbach

@DavidCarlisle that's why I m saying there is a huge difference between \fmtversion (format date) and bundle date. If we change doc we should update bundle date but no reason to change \fmtversion

David Carlisle

@FrankMittelbach sounds OK to me.

Frank Mittelbach

20:34

but if we change ltmath.dtx (codewise) we should change fmtversion and bundle date

bundle date should always (as a simple rule) reflect the newest file in the bundle

this way an update would always get a new bundle date (unless you do two uploads in a day :-)

David Carlisle

@FrankMittelbach yep changing format date would be a shame, but if early adopters or tl2015 pretest shows something then so be it. We'd still have the general rule that latexrelease options of 2015 or later use the "new plan" and dates 2014 or older use the old kernel, would just mean there were two dates in 2015.

Frank Mittelbach

@DavidCarlisle in this particular case I think we are pretty much ok with keeping the format date as a nominal 2015-01-01

David Carlisle

@FrankMittelbach yes today, I just meant we have a month of TL2015 pretest to survive:-)

Paulo Cereda

@egreg: not a nice result. :(

Frank Mittelbach

@DavidCarlisle @JosephWright can we change the fmtversion to 2015-01-01 beta (or would this break something? (if so could we fix it to allow for this? I think this would really the best (next time anyway but why not now just because it was put out there fore a day) ... we put it up as beta ... wait until near the end of the pretests and then change the upload to remove the beta

egreg

20:40

@PauloCereda Well, better 1:1 than other scores. ;-)

Paulo Cereda

@egreg Indeed. :)

Joseph Wright

@FrankMittelbach Petra's going to love us!

Frank Mittelbach

@JosephWright she is going to love you anyway :-)

Joseph Wright

@FrankMittelbach Yes, indeed

Frank Mittelbach

@JosephWright it can't really be avoided one way or the other

Paulo Cereda

20:42

@JosephWright Do not despair, after all the C stands for Comprehensive. :)

David Carlisle

@FrankMittelbach not without other changes I think, too much code assumes it's yyyy/mm/dd

Joseph Wright

@FrankMittelbach I miss having Robin to handle my uploads (it was basically just Philipp Lehman and me I think using tex.ac.uk for uploads)

Frank Mittelbach

but this beta to non-beta wouldn't mean somebody has to do a full upload of base ... it could be as simple as a single file

Johannes_B

David Carlisle

@FrankMittelbach ctan mechanisms really don't like single file uploads it seems, everything configured for full directory zip

Paulo Cereda

20:44

@JosephWright And me. :)

@Johannes_B awwwww <3

Joseph Wright

@FrankMittelbach They don't like single file updates (probably would need to get Rainer to do it)

Johannes_B

@PauloCereda Katja, the nice security guard just took that picture in our library. :-)

Joseph Wright

@DavidCarlisle Like I said, Robin was good for this

Frank Mittelbach

@JosephWright that's their issue then

Paulo Cereda

@Johannes_B Lovely picture!

Joseph Wright

20:45

@DavidCarlisle I may end up volunteering to sort out the UK node just to get easy access for this!

Frank Mittelbach

@JosephWright it is an offer

David Carlisle

@JosephWright and ftp put instead of pesky web forms with complicated questions:-0

Paulo Cereda

@JosephWright Naughty boy. :)

Joseph Wright

@DavidCarlisle They used to do that, I believe

Paulo Cereda

@DavidCarlisle LOL

David Carlisle

20:46

@JosephWright I only recently realised they had stopped:-)

Frank Mittelbach

@DavidCarlisle we could simply add another variable \fmtstatus and set that int the everyjob and the intro message

Joseph Wright

@DavidCarlisle I suspect might involve the fact that very few people would know how to use such a thing (me, Heiko, ...)

Johannes_B

@PauloCereda They definitely should get a copy of Quack, quack, Quack. Give My Hat Back

Paulo Cereda

@Johannes_B Would you like to translate it to German? Talk with Nicola about it!

It would be a great addition!

David Carlisle

@FrankMittelbach or just put "beta" in the existing ltpatch file:-)

Johannes_B

20:48

@PauloCereda I thought about it, but since it should rhyme ... I am bad at this.

Frank Mittelbach

@DavidCarlisle or that

@Johannes_B Not a requirement, don't worry about it. :)

Johannes_B

@PauloCereda But everything is more fun when rhyming, right? :-)

Paulo Cereda

@Johannes_B In the most delightful way. :)

Frank Mittelbach

@DavidCarlisle @JosephWright anyway my point is we are really doing a public beta so we should indicate that as it solves a bunch of hassles ... and with the format it would definitely be better to have "memorable days as far as possible

I mean tomorrow wold have been a nice one too ... but perhaps you guys don't like that

Joseph Wright

@FrankMittelbach We could do that if we get things sorted: I'm doing physics experiments and so will be lurking around my laptop most of the day

Frank Mittelbach

@JosephWright well perhaps I'm not too keen on making this release an April 1rst joke

David Carlisle

@FrankMittelbach I'd advise against it (one of my W3C recommendations happened to go out on 1st april, one of the major benefits of 2nd edition some years later was getting rid of that date;-)

Frank Mittelbach

@DavidCarlisle yes not this release

so let's stick with 1-1 or 5-1 in case we will get a serious set of updates for some unforseen reason

Joseph Wright

@DavidCarlisle, @FrankMittelbach See mail

Frank Mittelbach

21:24

@JosephWright saw

Joseph Wright

@FrankMittelbach Indeed: am handling now

Frank Mittelbach

@JosephWright as I said I'm happy to do the ctan entry updates (but not tonight)

Joseph Wright

@FrankMittelbach Oh no, not today: I'm off to bed in a minute

Frank Mittelbach

@JosephWright no DST?

Joseph Wright

@FrankMittelbach Yes, we are on summer time, so it's nearly bedtime for me

Frank Mittelbach

21:30

@JosephWright and what does this makes it at my end?

Joseph Wright

@FrankMittelbach Very late!

Paulo Cereda

21:43

@FrankMittelbach Party time? :)

Frank Mittelbach

@PauloCereda I'm pondering between opening a bottole of wine and a beer ... the book to read is already decided: The Soul of the Machine

Paulo Cereda

@FrankMittelbach Wine it is then. :)

Frank Mittelbach

@PauloCereda I think it rather calls for beer ...

this is not a romantic novel :-)

Paulo Cereda

@FrankMittelbach LOL

The Soul of a New Machine

The Soul of a New Machine is a non-fiction book written by Tracy Kidder and published in 1981. It chronicles the experiences of a computer engineering team racing to design a next-generation computer at a blistering pace under tremendous pressure. The machine was launched in 1980 as the Data General Eclipse MV/8000. The book won the 1982 National Book Award for Nonfiction and a Pulitzer Prize for General Non-Fiction. == Plot == The book opens with a turf war between two computer design groups within Data General Corporation, a minicomputer vendor in the 1970s. Most of the senior designers...

bought the book in Portland after meeting Tracy ... unfortunately afterwards so no sig

@FrankMittelbach Cool, I'll check it out.

The plot somehow reminds me of this: mayofamily.com/RLM/txt_Clarke_Superiority.html

I got me a Stephen King's book to read while I travel to Spain in the end of this month. :)

Frank Mittelbach

@PauloCereda this month ends in 6 minutes here

and for you probably in 6 hours and 6 minutes

are you trying an early April joke?

Paulo Cereda

@FrankMittelbach Oh I meant the end of April! :)

@FrankMittelbach I wish. :)

Frank Mittelbach

@PauloCereda what again was it that you study? nothing to do with precision has it? :-)

ough I duck

@JosephWright you probably saw it but I updated ltmath once more thanks to @Johannes_B

Paulo Cereda

@FrankMittelbach I have no idea anymore. :P

Frank Mittelbach

@PauloCereda as precise as that ... so I thought -- 'night folks

Joseph Wright

21:59

@FrankMittelbach :-)

Frank Mittelbach

@JosephWright midnight ... time to go

Paulo Cereda

@FrankMittelbach Good night, Frank! :)

Joseph Wright

@FrankMittelbach Indeed: I'm of in a second

Frank Mittelbach

same to you all

Paulo Cereda

@FrankMittelbach Wait a minute, what if it's April Fools joke?

And you are not leaving? :)

Yay Frank will stay!

Frank Mittelbach

22:00

@PauloCereda that's something you have to figure your self out

Paulo Cereda

@FrankMittelbach Oh no, I might need an stochastic model which includes beer variables. :)

Frank Mittelbach

I don't know about the tradition elsewhere but here in Germany one of the most respected computer Journals is producing April Joke articles now for many years and they are often so good that it is really dangerous to real the particular issue in this week

Paulo Cereda

@FrankMittelbach Oh my!

Frank Mittelbach

too many people got fooled and done horrible stuff (one of the best one was that the government is putting a tracking behind the numberplate or rather behind some extra bit that is put on the number plate to prove that your car is still fit to run

and reports say that several people peeled those off

If we write an algorithm and want to break the line , we use verbatim..
what if we write an equation?

@PauloCereda @egreg @barbarabeeton Do you maybe have an idea?

Q: How to break a long equation?

I have a long equation but long enough to occupy two lines. I want to break it to improve readability. How can I break it? \begin{equation} F = \{F_{x} \in F_{c} : (|S| > |C|) \cap (minPixels < |S| < maxPixels) \cap (|S_{conected}| > |S| - \epsilon) \} \end{equation} I wan to break it in...

equations line-breaking

@PaulGessler I tried this: \begin{multline}
y'=y+4 \pi \cos(4 \pi t)y \Rightarrow y'=(1+ 4 \pi \cos(4 \pi t))y \cap
\Rightarrow \frac{dy}{dt}=(1+ 4 \pi \cos(4 \pi t))y \\ \cap
\Rightarrow \frac{dy}{y}=(1+ 4 \pi \cos(4 \pi t)) dt

\end{multline}

but the equalities did not appear

@PaulGessler Why?

Paul Gessler

@evinda well, did you look in the log file? An empty line in display math results in an error.

evinda

@PaulGessler So what could I change? :/

Paul Gessler

23:58

@evinda it's simple: don't put empty lines inside displayed math environments (multline is one of these: a displayed math environment).
