@AndrewStacey It's no problem. We probably disappeared at the same time; I had a meeting to go to. Feel free to ask random language questions when we're in chat.
@StefanKottwitz: would you need any particular image for your TUG presentation? Jin sent me a vector format of the TeX.sx logo, in case you need it. Or any image I can make it. :-)
@Canageek It depends what you are up to. Addition to double bonds is certainly possible: some people here (UEA) are using this to look at diffusion in micelles
We've been trying using muons to look at addition of hydrogen to metal species: we got some data, but the time scale is probably a bit short for us
@Canageek As you're in Canada, you are at the advantage of having access to TRIUMF (and also Donald Arseneau, not only a muon person but also a TeX expert)
luaotfload uses an internal database that gets updated with mkluatexfontdb. So it knows about a lot of fonts installed on my computer. How can I query this database? Something like
luatexfontdb --list-fonts-on-my-computer-that-are-in-your-database
?
@JosephWright Probably it's best to discuss about robust commands here. When you define \newcommand{\xyz}[1][default]{...#1...} (there can be any number of regular arguments, up to 8) then \xyz is robust, as it expands to \@protected@testopt \xyz \\xyz {default} which, when \protect is not \@typeset@protect, eventually expands to \protect\xyz.
@JosephWright I think I saw a presentation by the guy doing addition of Muons to things when I was working in Vancouver this summer- I was at the TRIUMF user group conference.
@JosephWright By do things with I meant make into molecules that I can actully have around for a while, at least long enough to characterize.
@JosephWright I'm actually interested in hot-atom chemistry with radioisotopes that have at least a few hours half-life, muons seem a little shortlived to me.
@egreg To me, that's not robust as it expands at all: the LaTeX3 view on preventing expansion is the \protected one: something protected should not change at all
@egreg Also, doesn't \protected@testopt only works inside a \protected@edef, not a 'raw' \edef
@JosephWright In fact I remembered the muon presentation was odd, because he used a PDF of pages instead of slides. Good talk though, I wanted to ask him about it after but wasn't able to meet up with him.
@JosephWright It depends on what notion of robustness you have in mind. The traditional LaTeX meaning is "it can go in moving arguments without creating problems", which amounts to say that it can go through \protected@edef. Of course \protected macros are more robust, as they won't depend on the current meaning of \protect and can go through \edef.
@egreg There are some things that don't work properly even if 'LaTeX robust' which do if 'engine robust'. e-TeX is hardly new, so my working definition is 'engine robust'. (For example, see some discussion in the siunitx manual about the first item in a table cell.)
@JosephWright: I tried it and thought it was a bit manky at first sight. Changing the fontsize to suit my old eyes wasn't clear (I did it in the end, but struggled). Then CTRL-V copies the whole entry, apparently, while I was expecting it to copy "\cite{<keys-of-selected>}. Maybe I'm just grumpy today...
@JosephWright Aha! Ctrl-K - I guess I need to RTFM. But I have this awful tendency to make my time-investment decisions based on first impressions. That's one of the reasons I'm a Memoir, rather than a Koma fanboy.
I use XeLaTeX for my documents, and have a font set that I like. However, I also work with coauthors who aren't quite ready for xelatex yet, and use PDFLaTeX (or even plain LaTeX).
I'd like to construct a macro that includes certain content (fontspec and certain font packages) if I use XeLaTeX a...
Some days ago, me, @PauloCereda and others were talking about indexes in LaTeX. Now a friend of mine needs to build two indexes: one in Spanish and the other one is the translation into English of the first one. I've really never done much work with indexes, so I don't know what to suggest to my friend as the best approach. What packages would you suggest?
@egreg memoir tries to avoid other packages to avoid dependencies. The result is that ALL packages have to check if they are compatible with memoir :-(
@MartinScharrer Yes. In this case it's even worse! In order to avoid using up the write streams, memoir writes all the \indexentry commands in the .aux file and writes the .idx files at end document, which defeats the main feature of imakeidx, that is, of processing the .idx files as part of the typesetting run. But it turns out that hijacking memoir's index processing with ours, all goes well.
@GonzaloMedina I drew it by hand in Inkscape. The lion was quite annoying to draw because of all the details. The sombrero was nice to draw, I think it really fits the lion. :-)
@StefanKottwitz No, there's no local TeX user group in Colombia. There's CervanTeX (mainly a Spanish group and I am a member, but it doesn't have much activity) and there's also a Mexican group (I think).
@PauloCereda Mico's answer is prolix and little informative; Peter Grill's is wrong (the O is usually in italics); Werner's is wrong too (\mathcal{O}?) and abuses \ensuremath. I've not given negative votes to them, but I'd not give upvotes either.
@JosephWright I have finally found out what happened: My dog ate the answer. (No, actually it was Aditya, and he didn't ate it, but deleted it because it was not an answer to the question.)
@egreg Ah, I see. Unfortunately, I don't understand most of those math commands, so I didn't notice why they were downvoted. I just found curious of three answers with negative score in less than 1 hour. ;-)

You can use the ConTeXt script mtxrun to get this information:
$mtxrun --script fonts --info --list --name --pattern="*Cambria*"
mtx-fonts |
mtx-fonts | mapping : cambriaitalic
mtx-fonts | fontname: cambriaitalic
mtx-fonts | fullname: cambriaitalic

How can I the code for "big omega", NOT \omega which is little omega. I want the symbol that's used in big-O notation.
