@Nasser It's already quite a bit bigger than most textbook pages, so you don't have to print on all of it of you don't like the aspect ratio.

Nasser

@DavidCarlisle, I am not following. I am just talking about long equations like (......) that can't be broken by default by latex since it has starting and closing (). When I change to 2 columns, these equations flow now into the right or left column, overflow. So I have to manually fix each one to make it fit. If the whole page was a little wider, then I do not have to do this.

Here is an example

The above is letter size, 10 pt, 2 columns.

With one column, this problem is not there ofcourse.

David Carlisle

@Nasser yes you would, you'd just have bigger equations:-) Math typesetting is hard that's, If you want automatic breaking you should look at breqn package. Some math journals that use two column make heavy use of full with floating equations, so you treat an equation like a figure* and let it float to top of page, or you just out the work in to breaking them by hand (easier to do it as you enter than change your mind later,

Nasser

But I learning now from a book how to break equations manually.

@DavidCarlisle thanks! Will look into this brenq package. if I do not have to edit all this by hand, that will be better. Will read on it tonight

Paulo Cereda

@cmhughes Hi Chris! Actually no, I'll take a look. :)

David Carlisle

12:17 AM

@Nasser Sadly Michael (who did most of the ams... package work as well) died very young but breqn was/is still the state of the art with automatic breaking of display math.

cmhughes

@PauloCereda it's quite interesting- I tried to find a solution, but couldn't get arara to acknowledge a function... will be interested to know what's going on :)

Paulo Cereda

@cmhughes Could you try something for me? Try prefixing your example with bash -i -c <function>

cmhughes

12:47 AM

@PauloCereda ok, one sec...

@PauloCereda success :)

Paulo Cereda

@cmhughes No arara question should be unanswered. :)

cmhughes

@PauloCereda totally- I have some code for you if you want to post it as an answer :)

Paulo Cereda

@cmhughes Then go ahead and write the answer. :)

cmhughes

@PauloCereda well, you solved it :) I'm happy to post an answer, but would also be very happy to vote on an answer that you post :)

Paulo Cereda

@cmhughes Don't worry, my friend. :) Post it and I'll upvote it. :)

cmhughes

12:51 AM

@PauloCereda ok, if you're sure :) I'm happy to spread the wonderful word of arara :)

will write the answer soon- my niece is wanting to play 'Guess who'... I will return after my victory

2:53 AM

I am wondering if I am doing something silly here or I can post this as question. Just first time to use breqn. I took small example from what I have, and used \begin{dmath} and \end{dmath} but I get errors. Can someone please just have a quick look if I am doing something not supposed to do? I am following example shown here stackoverflow.com/questions/1578127/…

Here is my MWE

\documentclass[letterpaper]{article}%
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{breqn}
\begin{document}
\begin{dmath}
q^{\prime}\left(  t\right)   =\operatorname{Re}\left(  i\omega_{n}\left(q_{0}-i\frac{q_{0}^{\prime}}{\omega_{n}}\right)  e^{i\omega_{n}t}\right)
                             =\operatorname{Re}\left(  \left(  \omega_{n}q_{0}-e^{i\frac{\pi}{2}}%q_{0}^{\prime}\right)  e^{i\frac{\pi}{2}}e^{i\omega_{n}t}\right)
                             =\operatorname{Re}\left(  \left(  \omega_{n}q_{0}e^{i\frac{\pi}{2}}-e^{i\pi}q_{0}^{\prime}\r…

the code is AUTO-generated. I just put dmath around it. Error I get is

(/usr/share/texlive/texmf-dist/tex/latex/amsfonts/umsb.fd)
! Double subscript.
<recently read> \mathsub

l.23 ...{i\frac{\pi}{2}}+q_{0}^{\prime}\right) }}
e^{i\omega_{n}t}\right)
?

This is the original MWE, which compiles OK

\documentclass[letterpaper]{article}%
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}

\begin{document}

\begin{align*}
q^{\prime}\left(  t\right)   &  =\operatorname{Re}\left(  i\omega_{n}\left(
q_{0}-i\frac{q_{0}^{\prime}}{\omega_{n}}\right)  e^{i\omega_{n}t}\right) \\
&  =\operatorname{Re}\left(  \left(  \omega_{n}q_{0}-e^{i\frac{\pi}{2}}%
q_{0}^{\prime}\right)  e^{i\frac{\pi}{2}}e^{i\omega_{n}t}\right) \\
&  =\operatorname{Re}\left(  \left(  \omega_{n}q_{0}e^{i\frac{\pi}{2}}%

So I just added breg and replace align* by dmath, and removed the & and removed the \\ at the end. Just like that answer did.

Nasser

4:10 AM

FYI, please ignore the above. I just posted a question on this in main board.

doctorate

5:48 AM

@PauloCereda, may be if you konw how to let the KAMEL (YAML) count form 1 to 60 seconds in clear rule, which won't harm anyone, but would IMHO, wait until Dropbox deamons finish their dancing on the carcase files, then clear comes in handy.

@PauloCereda, a few seconds pause before the delete commands in the clear rule might save the day.

tohecz

6:35 AM

@doctorate @Paulo This can be added as an optional parameter to the rule, like: clear { wait: 60 }

Nasser

7:06 AM

Why does Latex automatically stretch material to fill all the page before starting new section at the top of the next page, even though I never said \newpage at the end of the last section? Is there some automatic flushbuttom in effect? It makes the output look bad.

I can post this as question, but I assume it is just some setting that I do not know about.

Werner

@Nasser You can use \raggedbottom to avoid this...

Nasser

When I add \newpage at the end of the last section, then it does NOT stretch the matrial. So no gaps are seen. But I do not mind new section starting on the same page.

@Werner I am NOT using \raggedbottom

Werner

@Nasser I'm suggesting you can use \raggedbottom to avoid this stretching...

@Nasser ...some people also use the needspace package. It provides \needspace{<space>} and issue a page break if there is less than <space> vertical space available on the page.

Nasser

I added \raggedbottom to the preample, but it did not help.

Werner

See the needspace documentation for a short description.

Nasser

7:15 AM

Just added \usepackage{needspace} (but removed the \raggedbottom ) and compiled. Not much better. Still lots of gaps. Latex is trying to fill the page for some reason to the bottom, before starting new section on next page. Only solution is to add \newpage explicitly.

hi

@Ethan hi.

how is life

The problem is that it can't start the new section where the first section ends, because the new section start with large image, which won't fit. So it wants to start new section on new column (which is next page). fine. But why it stretches the matrial is what I do not understand. I will look more into it.

Werner

@Nasser You need to include an explicit \needspace{<length>} for it to work effectively.

Moreover, there are differences in how document classes handle sectioning and the spacing around it. It's advisable to replace the problem for it to be adequately assessed.

@Ethan: This site (or chat room) is not MathJax friendly...

...since content here is based on the code, and not necessarily the rendering of it.

Nasser

7:30 AM

@Werner I do not know how needspace works. I did :
\usepackage{needspace}
.... then in the problem area, at end of the section, I write...
\Needspace{2cm}
\section{..}
\includegraphics{...}

but it still streches things. I do not understand what is this space I am asking for. I am starting to feel now like I am using Microsoft word where I have to tell it what to do on each part :(

I'll just add a \newpage, that works.

Grey

7:46 AM

Good morning all! Werner! I've been playing around with your code. I was wondering if you'll have an idea how to approach this modification of your command: tex.stackexchange.com/questions/119163/… I've spend a good bit of time trying to get it sorted. I wish I knew how to create custom commands meself!

Ethan

Is this the Christianity chat room

Nasser

8:19 AM

I was wondering what might cause \raggedbottom not do its job?

\documentclass[letterpaper]{article}%
\input{commonlatex}
\raggedbottom

I would really like to know. I can ask this at main board, but having hard time making a MWE

I can put my whole latex file and all the images in a zip file on my site, so it is all self contained. but not sure if this would be accepted.

2 columns, article, lettersize. Latex insists in stretching text to the bottom of the second column because it can't start next section there.

and I am using \raggedbottom

When I add \newpage, this happens ....

But should not this happen automatically when I use \raggedbottom ??

without having to use \newpage explicitly ?

I can post this at main board if it is worth while...

may be it is the 2 column layout which is confusing \raggedbottom

I use

\documentclass[letterpaper]{article}%
\raggedbottom
\begin{document}
\begin{multicols}{2}
\tableofcontents
.....
\end{multicols}
\end{document}

percusse

@Nasser When you want to test these things out, make a MWE. It's simple with lipsum. Fill the first column with dummy text and post a MWE. It can be happening due to many interacting packages or some directive forgotten somewhere in the preamble. Partial questions will make things worse for you.

Nasser

@percusse I can't really make a MWE. This document has lots of pictures and things. If I spend time to reproduce this it will take me forever. I allready have an example in front of me. I can make it complete in a zip file. But I do not feel folks will accept that.

percusse

8:35 AM

@Nasser Yes you can. Just use lipsum or kantlipsum packages.

David Carlisle

9:28 AM

@Nasser probably you want multicols* (unbalenced columns)

Grey

would anyone know where I can start with solved my bracket problem? tex.stackexchange.com/questions/119163/… I'm trying to figure out if its to do with dealing with the code here:\NewDocumentCommand{\dboxbrace}{s O{\{} O{\}} O{0.05\linewidth} m O{0.4\linewidth} m }{% \lrboxbrace[<lbrace>][<rbrace>][<lwidth>]{<ltext>}[<rwidth>]{<rtext>}

Nasser

@DavidCarlisle, thanks, just tried it. did not fix the problem. I am trying to make a MWE, but so far, no success duplicating it. But I need to work more on it. This is my current example

\documentclass[demo]{article}
\RequirePackage[demo]{graphicx}
\usepackage[nopar,numbers]{kantlipsum}
\usepackage[left=.7in,right=.5in,top=.7in,bottom=.9in]{geometry}
\usepackage{multicol}
\raggedbottom
\begin{document}
\begin{multicols}{2}
\section{one}
\kant[1-5]
\section{two}
\includegraphics[width=8cm,height=10cm]%
\kant[1-4]

\end{multicols}
\end{document}

But the above does NOT stretch....

I must have something else causing it to stretch in the other file, will keep looking

I think I got it !

Please see this

\documentclass[demo]{article}
\RequirePackage[demo]{graphicx}
\usepackage[numbers]{kantlipsum}
\usepackage[left=.7in,right=.5in,top=.7in,bottom=.9in]{geometry}
\usepackage{multicol}
\raggedbottom
\begin{document}
\begin{multicols}{2}
\section{one}
\kant[1-5]
\section{two}
\includegraphics[width=8cm,height=10cm]%
\kant[1-4]

\end{multicols}
\end{document}

is this worh posting on main board, or I am just doing something silly?

This is even better example:
\documentclass[demo]{article}
\RequirePackage[demo]{graphicx}
\usepackage[numbers]{kantlipsum}
\usepackage[left=.7in,right=.5in,top=.7in,bottom=.9in]{geometry}
\usepackage{multicol}
\raggedbottom
\begin{document}
\begin{multicols}{2}
\section{one}
\kant[1-5]
\section{two}
This is start of section two.

\includegraphics[width=8cm,height=10cm]%
\kant[1-4]

\end{multicols}
\end{document}

I have \raggedbottom

David Carlisle

9:44 AM

@Nasser \raggedcolumns

Nasser

Example again, has small thing not right. But still show the problem.
\documentclass[demo]{article}
\RequirePackage[demo]{graphicx}
\usepackage[numbers]{kantlipsum}
\usepackage[left=.7in,right=.5in,top=.7in,bottom=.9in]{geometry}
\usepackage{multicol}
\raggedbottom
\begin{document}
\begin{multicols}{2}
\section{one}

\section{two}
This is start of section two.

\includegraphics[width=8cm,height=10cm]{}

\kant[1-4]

\end{multicols}
\end{document}

@DavidCarlisle OMG !!! That was it. YOU ARE AMAZING. I really should post this on main board so you can answer it. I had no idea there is even such a thing. Should I post it, I think it will be useful.

\raggedbottom
\raggedcolumns % !!!!!

David Carlisle

@Nasser it's not hard you go texdoc multicol and then C-f ragged and see what it says. It's not as if I actually remember all this stuff.

Nasser

@DavidCarlisle but this assumes one knows the problem is there to even know where to look ;)

David Carlisle

@Nasser well it's like looking up a spelling in a dictionary, it's easier if you know how to spell the word.

@Nasser this is of course the reason why a journal would always insist that figures go in a float so you don't have this problem with bad page breaks.

Nasser

It is like saying the meal did not taste good , and then trying to determine which ingredient was the cause. There are so many. but thanks again for your help :)

I thought the figures are float by default? the figure at the start of the new section was just too long to fit. I do not use [h!] or [ht] or any of this.

David Carlisle

9:53 AM

@Nasser You haven't used a figure you have just put \includegraphics in the main stream so that doesn't float it is postioned teh same way as a letter is positioned, it's just bigger

Nasser

start of section...

\section{Problem 3}%
\begin{center}
\includegraphics[scale=0.6]{problem_3_description_small.png}%
\end{center}

David Carlisle

@Nasser exactly That's why you got a bad page break.

Nasser

So, you saying one should put images inside figure all the time so they float?

David Carlisle

@Nasser the whole reason for having floating environments is to allow the system to float the large insert away from the page break.

@Nasser It depends on priorities, sometimes the material is such that you really want the figures inline, but for that kind of lumpy content you have to accept bad white space (adding \ragged... just moves the bad space to the botton)

Nasser

@DavidCarlisle, you are right, just tried it with
\section{...}
\begin{figure}
\includegraphics[scale=0.6]{problem_3_description_small.png}%
\end{figure}

and without using \ragged anything. and now the problem went away. But the figure went very far away from where I wanted to be. So floating figures do not really do it. I like the \raggedcolumn more, since now the image is where I want it and also no stretch

Grey

10:01 AM

i'm trying an alternative to the braceket thing, but defing two bracket command and merely attempting to use them together, but I cannot get them to be on one line together. How can I do that? Should I post this to my original thread?

David Carlisle

@Nasser yes if you float the figure you have to caption it and arrange the text to refer to the figure rather than assume it is just there. But getting less bad space at page breaks is why there is a floating system (whether or not you use it in this case)

Nasser

@DavidCarlisle sure. I understand about the \ref and tags. But I really like the image to be where I want it, I do not like to have to flip a page or 2 to see an image, then go back. Nice to have it where the discussion about is, right there at that spot. For me, any way.

David Carlisle

@Grey You are missing

\newbox\leftbox
\newbox\rightbox

and then if you put the line in an mbox you see why it was breaking:

\begin{document}

\mbox{\ldboxbrace {abc}{abc}\rdboxbrace {abc}{abc}}

\end{document}

puts it all on one line as mbox never breaks but TeX says:

Overfull \hbox (21.12148pt too wide) in paragraph at lines 46--47

@Grey So you need to make the target widths of your boxes a bit smaller

Grey

thanks David, I'll play around here now

Grey

1:38 PM

I've added an mbox; and the surrounding tex seems displaced by the mbox.

How can I prevent it from causing so much huge gaps between the paragraphs?

Grey

2:02 PM

I've tried adding a \vspace but it caused a massive destruction in the whole document. How can I sort out this issue?

David Carlisle

@Grey probably you need to add an example to the q (mbox shouldn't affect the vertical space, other than stopping a line break between th eboxes)

@Grey You probably want \raggedbottom

@Grey don't do this at the end of the mbox

}
}

it puts a word-space at the end of the box stopping you go up to the right margin. You also have a word space and a \par (blank line) between the two boxes the \par is ignored in an mbox but it would be clearer not to have it (then probably you wouldn't need the mbox at all as the two boxes would be naturally on the same line.

On no I was getting a nice run of palindromes for 1xx,xx1 but someone just downvoted me (without saying why:-) so now I have a 4 at the end so need to get 300000 rep more:( I blame @PauloCereda he uses vim, what can you expect. Ah If I reach rep cap today I suppose I can restore parity. Hmmm

doctorate

@PauloCereda, Hi again, thnks for your response regarding arara and dropbox, but I still believe that you can do it.

I mean clearing files after compilation, cleaning the messy folder, finally, one can discover what other files were written and forgotten!

Paulo Cereda

5:14 PM

@doctorate Hello. :) I'm deeply sorry, but having an "automatic" way of cleaning files seems to defeat the purpose behind arara. The default directives are shipped with some principles in mind (one of them is the KISS one, where simplicity should be a key goal in design and unnecessary complexity should be avoided), and I'm not inclined to include that layer of complexity. Of course, users are invited to write their own rules when arara's default ones don't seem to fit the bill.

@DavidCarlisle Hey I upvoted a lot of your answers. :)

David Carlisle

@PauloCereda I know thanks (not all my comments in chat are true, but you do admit to using vim, don't you?:-)

Paulo Cereda

@DavidCarlisle Guilty as charged. :)

David Carlisle

@PauloCereda You can tell us all about it when you do your interview

Paulo Cereda

@DavidCarlisle Oh no!

:)

doctorate

@PauloCereda, sorry if kissing rule would be broken, that was not the intention, but for a noob like me an optional argument in the clear rule like [wait : 60] would be a black vodoo magic in arara wonderful land.

David Carlisle

@PauloCereda This is almost a year old :(

Jul 16 '12 at 22:20, by David Carlisle

Paulo Cereda

@doctorate Don't worry. :) My advice is then for you to extend the clean rule to your own needs. Can't remember if Windows has some sleep command; if it does, write a new clean directive with a list of commands and add both the removal and sleeping commands in the list (a list of commands is described in the manual). :)

@DavidCarlisle ooh! :)

doctorate

@PauloCereda, in windows may be this: powershell -command "Start-Sleep -s 60"
