well, I'll get a minus next week, I'm on the conference and my computer has no battery :/

@PeterGrill do you think I should post an answer?

Peter Grill

@cmhughes Yes since that sure seemed to have fixed everything. But, still would be good to know why color was having that effect.

cmhughes

@PeterGrill yes, that's why I'm hesitant :) Am trying to find other commands that produce the same behaviour....

Peter Grill

@cmhughes Better hurry before David gets here. He has a slight advantage when it comes to color. :-)

cmhughes

@PeterGrill I'd always bow out to David :)

Peter Grill

@cmhughes Yeah I know, but still fun to get a tick for something he has an unfair advantage. :-)

@Vivi Just curious, would you like all your equations colored blue?

cmhughes

@Vivi can you post the code that gave you the image?

this one: dl.dropbox.com/u/1885087/cmhughes.png

Vivi

@hpesoj626 I wanted to set them apart from the others, since it is the definition so to say. I have many of them one after the other and it is hard to see which ones are the main equations.

@cmhughes one sec

\begin{equation*}
R_{l,t}L_{t+1} = \Omega(\oo_{t+1}) Q_{H,t+1}H_{t+1}
\end{equation*}
\begin{align*}
\hat{R}_{l,t} + \hat{L}_{t+1} &= \widehat{\Omega(\oo_{t+1})} + \hat{Q}_{H,t+1} + \hat{H}_{t+1}\\
\hat{R}_{l,t} + \hat{L}_{t+1} &= \frac{\Omega'(\oo) \oo }{\Omega(\oo)} \widehat{\oo}_{t+1} + \hat{Q}_{H,t+1} + \hat{H}_{t+1}
\end{align*}

\begin{gather*}
R_{l,t}L_{t+1} = \Omega(\oo_{t+1}) Q_{H,t+1}H_{t+1}\\
\begin{align*}
\hat{R}_{l,t} + \hat{L}_{t+1} &= \widehat{\Omega(\oo_{t+1})} + \hat{Q}_{H,t+1} + \hat{H}_{t+1}\\

sorry, you need \documentclass{article}

etc...

oooops...

sorry, I forgot... Let me turn it into a MWE. I defined \oo in the preamble.

hpesoj626

so a global setting will not work I see. Well it seems like @cmhughes is working on it.

cmhughes

@hpesoj626 yep, as soon as I know what \oo is :)

Vivi

dl.dropbox.com/u/1885087/cmhughes.tex

Sorry, that was just a screenshot of the part that showed the example. I didn't have a MWE. Now it is there. \oo is just \newcommand{\oo}{\overline{\omega}} because I use it a lot :)

cmhughes

6:16 AM

@Vivi so you want it to look like the first version, except without the extra vertical space?

hpesoj626

@Vivi I would suggest defining a new math environment with the color settings so as to avoid repetitive manual setting of color if that were possible with your current set up.

Vivi

So @hpesoj626 I want only the key equations (the definition equations) to be coloured so I know where the stuff starts, I know which equations are key. This is just a file with my workings, because I do my math workings on the computer...

@cmhughes Yes, but I didn't colour the MWE I showed you. But basically yes.

Igor Kotelnikov

@JosephWright @Speravir:

cmhughes

@Vivi I don't really have an answer, other than some manual \qquad - how about

\begin{align*}
R_{l,t}L_{t+1}& = \Omega(\oo_{t+1}) Q_{H,t+1}H_{t+1}\\
\hat{R}_{l,t} + \hat{L}_{t+1} &= \widehat{\Omega(\oo_{t+1})} + \hat{Q}_{H,t+1} + \hat{H}_{t+1}\\
\hat{R}_{l,t} + \hat{L}_{t+1} &= \frac{\Omega'(\oo) \oo }{\Omega(\oo)} \widehat{\oo}_{t+1} + \hat{Q}_{H,t+1} + \hat{H}_{t+1}
\end{align*}

or does that not work?

Igor Kotelnikov

@JosephWright @Speravir: I have no objection regarding free distribution of my book LaTeX by Russin (LaTeX по-русски) although I would not admit this fact legally.

cmhughes

6:24 AM

@Vivi sorry, I've got to go to bed- I'll check back tomorrow, I'm sure a guru will be able to fix it with you :)

Vivi

I could do that and add a [1cm] after the first \\ to set the first equation apart from the others. It is OK, other than the fact that in this case the first equation is aligned with the rest, which I would prefer not to. I like it that the first equation is centered by itself. But again, it is not a big deal since this is a file that no one will ever see except me!

@cmhughes I was just curious about the spacing with \color{ } and later with gather which I had never heard of

Maybe gather will be useful to me in the future...

@cmhughes I thought perhaps \color{} was not supposed to be used with math, or that I was using it wrong.

hpesoj626

@Vivi it seems like \color{} does not mess up spacing inside align. But i see your point about centering the first equation. This looks like it's beyond my abilities too.

Vivi

@hpesoj626 Yes, probably align + spacing after the first eqn is the best option here...

It is hard to understand what the OP wants

Vivi

@hpesoj626 Are you talking about me?

hpesoj626

@Vivi A recent OP whose question got 3 answers. OP accepted mine but it wasn't clear at first what OP wants.

Vivi

@hpesoj626 OK :)

hpesoj626

7:36 AM

Is it just a problem with my slow connection or ctan is temporarily down?

Faheem Mitha

7:59 AM

@tohecz Sounds like a good plan to me.

Usually research projects have some senior person involved, part of whose job it is to know what has been done and what has not been done in the field. Was this not the case here?

@hpesoj626 I think it is down. I'm seeing a unavailability notice.

David Carlisle

@Vivi just saw this comment but always beware of \color at the start of anything it's notmally only a problem in vertical mode like a p column where \leavevmode\color{... usually fixes it but it's not impossible it could mess up other constructs too

@cmhughes quite right too (but I haven't yet seen what the actual question was:-)

tohecz

@FaheemMitha it is, my supervisor even is that kind of person who daily reads the arXiv feeds and goes through the new jounral issues ToCs etc., in spite of this, he didn't know of this result, it is a single-author article of a person doing something completely different as his primary research, and it wasn't published in a mainstream journal...

damn, 8 hours and @GolzanoMedina hits rep cap?

Faheem Mitha

8:24 AM

@tohecz I see. That sounds unfortunate.

tohecz

@FaheemMitha yeah. Shit happens, but I try to take it easy

Faheem Mitha

Does the rep cap open and close start and close at the same time for everyone?

@tohecz In general, the citation network effect is strong enough in an active field that one will be led to most relevant work, but I guess it is possible for stuff to fall through the cracks.

Also proprietary journals have this maddening thing called paywalls, so you cannot even look at the article to see if it is relevant unless you pay. Of course writing to the author, if reachable, is possible, but is extra work.

tohecz

8:44 AM

@David Is there a penatly mechanism to control number of lines of a paragraph? Such that setting a high number to some penalty would favorize line breaking with as few lines as possible?

David Carlisle

8:55 AM

@tohecz not exactly but there is:

But there's one more feature,
called ``looseness''; some day you might find yourself needing it,
when you are fine-tuning the pages of a book. If you set |\looseness=1|,
\TeX\ will try to make the current paragraph one line longer than its
optimum length, provided that there is a way to choose such breakpoints
without exceeding the tolerance you have specified for the badnesses
of individual lines.

tohecz

@DavidCarlisle ok, not what I would need, but thanks

David Carlisle

@tohecz Oh in that case you may be looking for ..

\linepenalty the higher you make that the less likely long paras will be

tohecz

@DavidCarlisle ok, thats it. But seems that \looseness=-1 solved @Peter 's problem ;)
