TeX, LaTeX and Friends - 2015-04-02 (page 1 of 2)

Faheem Mitha

6:25 AM

@cfr Not really. I just want a bit of a gap.

Is \hspace a reasonable all-purpose thing to use for horizontal spacing? That's what I normally use.

David Carlisle

7:37 AM

@FaheemMitha yes except of course you should always feel bad if adding explicit spaces:-)

Faheem Mitha

@DavidCarlisle Why?

David Carlisle

@FaheemMitha because it's better to use \section{Introduction} than \vspace{5ex}\textbf{1}\hspace{2em}{\large Introduction}\par\vspace{3ex}

Faheem Mitha

@DavidCarlisle agreed, but in this particular context there doesn't seem to be a natural spacing command. Context:

\rohead{\jobname.tex\hspace{0.5cm}\today}

Joseph Wright

@egreg I was just thinking I need to schedule this: probably you are right

Faheem Mitha

I wanted a little bit of space between the filename and the date.

@JosephWright do you use any of the KOMA classes?

Joseph Wright

7:42 AM

@FaheemMitha Not routinely: @NicolaTalbot does

Faheem Mitha

@JosephWright Ok.

They are quite impressive. Clearly a lot of work has got into them. Not the mention the documentation. If it is a German thing, that would go some way towards explaining it.

David Carlisle

@FaheemMitha yes you're let off, anyway setting up the page head is not really any different from setting up section headings, you have to specify the space somewhere but if you were routinely adding hspace after filenames in the document it would be an indication that you are missing a \newcommand defining some structural filedate thing...

Faheem Mitha

@DavidCarlisle well, if you can suggest a better, more LaTeXy markup way to do it, I'm all ears.

BTW, I get the impression that scrlttr2 is ignoring the regular spacing commands, e.g. oddsidemargin, evensidemarge, topmargin. Is that possible/likely?

David Carlisle

@FaheemMitha no you have to use hspace at that level, but that's Ok you are not typing explicit \hspace on every page, you are setting up the page layout.

Faheem Mitha

@DavidCarlisle ok. thanks.

Joseph Wright

7:57 AM

@DavidCarlisle Think I've tracked down the texsys.cfg issue (why it's not appeared in the TDS-style zip)

Faheem Mitha

8:48 AM

Does anyone have suggestions for a good, decorative font for a letterhead?

@JosephWright btw, if that is a platypus, why a platypus?

I am using New Century Schoolbook in the form of fouriernc. Could I switch to a different version of that font?

David Carlisle

9:02 AM

@JosephWright were you also getting the runaway * prompt or was that something I had locally?

Joseph Wright

@DavidCarlisle Probably was but didn't worry about it :-)

@DavidCarlisle Am trying to track down why texsys.cfg doesn't get kept to transfer to TDS-zip: I've got the general issue isolated

David Carlisle

@JosephWright users of non hierarchical and extension-less filesystems will be grateful for the fix:-)

Joseph Wright

9:14 AM

@DavidCarlisle Problem isolated: we need to avoid doing any searching at all (even local dir) when unpacking base as texsys.cfg is extracted strangely

Faheem Mitha

A: Why is LaTeX3 taking so long to come out?

When Don Knuth wrote TeX he wanted to create "just a typesetting language" but in response to user demand the macro language grew and grew. He also said that, if at the time he wrote TeX there was "a universal simple interpretive language that was common to other systems, naturally I would have ...

Could one really implement something like TeX in Python?

Though I'm not sure exactly what that answer is suggesting.

David Carlisle

@JosephWright idea was you'd only have initex and no docstrip or latex or anything else, so it's a bit primitive...

Joseph Wright

@FaheemMitha JF's idea is to implement the input parser in Python and then create essentially plain TeX code for typesetting

David Carlisle

@FaheemMitha latexml implements pretty much all the tex macro language in perl. Just not the typesetting bits

Joseph Wright

@DavidCarlisle Understood

Faheem Mitha

9:18 AM

@JosephWright do you think that makes sense?

@DavidCarlisle Oh. Did you write it (latexml)?

David Carlisle

@FaheemMitha no but I know a man who did;-)

Faheem Mitha

@DavidCarlisle oh, ok.

Joseph Wright

@FaheemMitha The question is whether it can do the tricky stuff that one does in TeX by dropping down to the primitive level. The broad brush stuff is fine.

Faheem Mitha

@JosephWright Ok. So you don't know the answer to that?

David Carlisle

@FaheemMitha it makes sense in the abstract but it won't happen in that form. It is not really any different to what topskip is doing with lua, using lua rather than the normal tex input parser to construct all the document and just using the tex typesetting engine to typeset text once everything is assembled

Faheem Mitha

9:21 AM

@DavidCarlisle Ok. Is that luatex you are talking about?

David Carlisle

@FaheemMitha yes but most people give tex documents to luatex, Patrick gives it a lua program extracting database fragments so the tex macro expansion isn't used at all, he constructs paragraphs in lua which are then typeset.

Joseph Wright

@FaheemMitha The back-compatibly problem is large, the stability issue is there [Python 2/3 :-)], ...

Faheem Mitha

@JosephWright yes, Python isn't exactly stable, that's true. Something like CL might be better from that perspective.

@DavidCarlisle I don't follow. Who is Patrick?

Oh, topskip?

David Carlisle

@FaheemMitha user topskip's real name:-)

Faheem Mitha

So he is doing something special with luatex? In what context?

David Carlisle

9:27 AM

@FaheemMitha He has some answers on site somewhere, I haven't used his system myself, but the point is that in luatex to typeset a paragraph you need to pass a lua linked list of nodes to the paragraph builder, you can construct that list using tex scanning input text as normal but you don't have to you can build a lua linked list programatically in lua, the paragraph typesettimg routines don't care how the list was built.

@FaheemMitha see for example wiki.luatex.org/index.php/TeX_without_TeX

Faheem Mitha

@DavidCarlisle I see. Thanks.

That's an interesting writeup. Thanks.

He's probably right that handling things programmatically is easier with lua than with tex.

The link there is broken.

@topskip Your link is broken. In wiki.luatex.org/index.php/TeX_without_TeX#A_first_example

in "(or get the source here)."

Frank Mittelbach

@FaheemMitha the answer is making a pitch for his approach

Faheem Mitha

@FrankMittelbach Oh. Ok.

Faheem Mitha

9:53 AM

So, could this latexml thing be used as a better html converter?

latex -> html, I mean.

Frank Mittelbach

@FaheemMitha the reason that LaTeX3 has taken its time (and still does) doesn't have to do with a choice of coding approach (whether that being TeX internal based, or Lua, or Phython or what have you) but with the problem it intends to tackle - solving those is the issue and they aren't solved by dropping in a different interpreter. Have a look at latex-project.org/papers especially "E-TeX: Guidelines to future TeX extensions", or "The stony road to complex layout" and a few others

David Carlisle

10:09 AM

@FaheemMitha latexml and tex4ht have different strengths, have a look at dlmf.nist.gov for the output of latexml

Faheem Mitha

@DavidCarlisle Ok, thanks. But is tex4ht being maintained now? Its creator died.

@FrankMittelbach Yes, I was not implying that language switching would make any difference to a schedule. Nor was I suggesting any course of action.

David Carlisle

@FaheemMitha seems like it was taken up by River Valley, @michal.h21 seems to be the one with most tex4ht knowledge here:-)

Faheem Mitha

@DavidCarlisle Oh, the Indian people? Ok.

Joseph Wright

@FrankMittelbach Jonathan certainly is very keen on this plan

Faheem Mitha

I haven't used it for a long time. I once used it for some classes. That web page is still up I think.

David Carlisle

10:14 AM

@JosephWright Jonathan's always been keen on plans, just not always the same one.

Joseph Wright

@DavidCarlisle Indeed

@DavidCarlisle Oddly, though, he's been rather quiet of late on the committee list

Faheem Mitha

I think I used tex4ht for some of these. stat.unc.edu/students/faheem/teaching.html

It was not an unqualified success, but it worked.

Dr. Gurari was quite helpful with bug reports, I remember.

@DavidCarlisle this seems to be using MathJAX.

Is MathJAX usable with LaTeX, I wonder?

Hmm, is this up to date?

29

Q: Convert Latex to MathJax-HTML

Is there any tool that can convert Latex documents to HTML documents, so that all math is presented with MathJax? (Obviously, it is fairly easy to hack together a quick Perl script that is able to do a crude conversion, but I am interested in a bit more robust solutions — at least it should get ...

David Carlisle

@FaheemMitha I don't understand the question, mathjax has input parsers for latex-like math, mathml and asciimath, and converts them all to mathml, then renders using html+css, or svg or the browsers native mathml

Faheem Mitha

@DavidCarlisle Let me rephrase. What is the pipeline? LaTeX -> mathml -> MathJAX?

Paulo Cereda

@FaheemMitha As David said, MathJaX understands a subset of LaTeX-like math, that's about it.

Faheem Mitha

10:22 AM

Or, to be even more explicit. Can I write everything in LaTeX and convert it to something a web browser can understand using mathml?

@PauloCereda No, I meant mathml.

David Carlisle

@FaheemMitha mathjax only does math

Faheem Mitha

@DavidCarlisle yes, I understand that.

David Carlisle

@FaheemMitha yes tex4ht or latexml could do that or you could leave the math as tex syntax and rely on mathjax's tex parser.

Faheem Mitha

I would like to get from a LaTeX file to something I can stick on the web, that is all.

@DavidCarlisle ok

Is mathjax built in to a web browser, then?

Joseph Wright

@FaheemMitha No

Faheem Mitha

10:25 AM

I think tex4ht used to rely heavily on images. See e.g. stat.unc.edu/students/faheem/11/hw/hw1soln.html

@JosephWright ok

David Carlisle

@FaheemMitha it's written in javascript

Faheem Mitha

@DavidCarlisle Ok.

Faheem Mitha

10:47 AM

Does anyone have a good link for changing fonts on the fly?

Paulo Cereda

@FaheemMitha You mean, mid-document?

Faheem Mitha

@PauloCereda yes. Actually, I was thinking of using some fancy font in the header. Like a letterhead. Entirely frivolous, of course.

Joseph Wright

11:02 AM

@DavidCarlisle, @FrankMittelbach LaTeX2e update sent to CTAN plus l3build (as I had to make some adjustments)

David Carlisle

@JosephWright thanks:-)

michal.h21

@FaheemMitha you can configure tex4ht to output mathml, or to keep LaTeX which is then processed by mathjax, or you can produce images in various formats, which is not preferable, but svg is not that bas

Faheem Mitha

@michal.h21 Hi. Thanks for the information. Are you working on tex4ht?

topskip

@FaheemMitha Fixed, thanks for the notice!

Paulo Cereda

@topskip: Pat! :)

Faheem Mitha

11:10 AM

@topskip Thanks. Appreciate it. Good writeup.

topskip

@PauloCereda Hi!

@FaheemMitha Old, but still valid, I think.

yo'

Hello, everybody!

Paulo Cereda

@yo' Tom! <3

Faheem Mitha

@topskip I'll try your example. My browser is a pain about cutting and pasting.

topskip

@FaheemMitha All browsers suck.

yo'

11:12 AM

@PauloCereda btw, the song is great, but I think you made one mistake :-)

Paulo Cereda

@yo' Oh no! :) Do tell. :)

yo'

@PauloCereda there's wrong phrasing in twelve and eleven, you have "twelve" for two notes, but it's one syllable, and then eleven squeezed somehow

Paulo Cereda

@yo' uh-oh!

Faheem Mitha

@topskip But some suck more than others.

where does the main tex4ht repo live, does anyone know?

Paulo Cereda

@yo' Sorry. :(

yo'

11:17 AM

@PauloCereda don't worry :)

Paulo Cereda

@yo' <3

yo'

other than that it's soo cool, I couldn't stop laughing :D

Faheem Mitha

looks like svn.gnu.org.ua/viewvc/tex4ht. svn :-(

Paulo Cereda

@yo' :)

Faheem Mitha

So, if I do

\renewcommand*\rmdefault{iwona}

Johannes_B

11:26 AM

And the party begins, Daumen drücken.

Faheem Mitha

it looks from en.wikibooks.org/wiki/LaTeX/Fonts#Font_families like it should change the font, but nothing happens. Maybe I'm misunderstanding.

Anyone got a simple guide to switch fonts in the middle of the document? Right now I'm just trying to change the letterhead.

yo'

@FaheemMitha have you issued \rmfamily or \normalfont afterwards?

@FaheemMitha \fontfamily{iwona}\selectfont is for changing the family locally.

Faheem Mitha

@yo' no

@yo' Oh, is that all I need to do?

yo'

@FaheemMitha locally? Yes.

Faheem Mitha

@yo' Ok, trying now. Thanks.

Ooh, that works! Nice. And how do I switch it back to the default?

yo'

11:30 AM

@FaheemMitha \rmfamily or \normalfont or \fontfamily{\familydefault}\selectfont

Faheem Mitha

@yo' Oh, that's all? Don't I have to specify the font family?

yo'

@FaheemMitha there's always a default

Faheem Mitha

If I was previously using fouriernc, could I do

\fontfamily{fouriernc}\selectfont

?

michal.h21

@FaheemMitha I am fixing bugs mainly, and writing some helper scripts and documentation

Faheem Mitha

@yo' Oh, any of those three will work? Ok, trying now.

yo'

11:32 AM

@FaheemMitha yes, but you shouldn't. If fourier is your default font, you should choose it by telling LaTeX to choose the default font.

Faheem Mitha

@michal.h21 ok. how's it going?

@yo' ok, and the default is chosen at the beginning?

yo'

Or you can use groups: {\fontfamily{iwona}\selectfont In IWONA} Not In IWONA.

@FaheemMitha yes.

Faheem Mitha

@yo' That's good too.

@yo' that's great! Thank you very much for your help.

Oh, I see this one has it. I can't read -> ee.iitb.ac.in/~trivedi/LatexHelp/latexfont.htm

michal.h21

@FaheemMitha scripts are going well, documentation is worse

github.com/michal-h21/make4ht

github.com/michal-h21/tex4ebook/commits/master

github.com/michal-h21/helpers4ht/wiki

Faheem Mitha

12:17 PM

@michal.h21 Yes, I saw that.

And is River Valley working on tex4ht now?

Any idea what happened to Dr. Gurari's work with Braille? Sounds like useful work.

michal.h21

@FaheemMitha it seems only CVR is working on support for biblatex, he seems being really busy latety

Faheem Mitha

@michal.h21 does biblatex have anything to do with tex4ht?

michal.h21

@FaheemMitha tex4ht does have configurations for biblatex support

Faheem Mitha

@michal.h21 ok

Frank Mittelbach

12:46 PM

Faheem Mitha

3:51 PM

Hello. I'm having trouble getting LaTeX to see fonts.

If I do e.g. \fontfamily{uuni}\selectfont should it just find the font file? I have a file:

/usr/share/texlive/texmf-dist/tex/latex/universa/uuni.fd

for example, but I'm getting errors saying stuff like:

LaTeX Font Info: No file T1uuni.fd. on input line 104.

I do have:

\usepackage[T1]{fontenc} in there.

David Carlisle

@JosephWright we don't make an unpacked.zip?

egreg

@FaheemMitha The file name of the .fd file refers to the U encoding, not to T1.

Faheem Mitha

Ok, I guess I need to actually load the relevant package. If I can figure out which one.

egreg

@FaheemMitha \fontfamily{uni}\selectfont is the right command. With ONE u.

David Carlisle

@FaheemMitha not necessarily but \fontencoding{U}\fontfamily{uni}

Faheem Mitha

3:55 PM

@egreg I don't follow. So it is Ok as it stands?

David Carlisle

@FaheemMitha no you have the wrong family name

Faheem Mitha

@DavidCarlisle oh

David Carlisle

@FaheemMitha family is {uni} as above.

egreg

@FaheemMitha The family name is uni, available in OT1, T1 and U encoding.

Faheem Mitha

@DavidCarlisle ok

@egreg Ok. What is a good way of looking up families?

egreg

3:58 PM

@FaheemMitha There's none.

Faheem Mitha

@egreg bummer.

The only one I have got to work so far is iwona. And LaTeX finds:

`/usr/share/texlive/texmf-dist/tex/latex/iwona/t1iwona.fd`

The others don't have that t1.

I have to wonder why people post on Google+ instead of actual proper blog or something. Are they mental? Or do they see the word Google and lose their minds?

egreg

locate texlive/2014 | grep '/[tT]1.*\.fd$'

David Carlisle

@FaheemMitha what have you against g+ ?

egreg

@FaheemMitha I get 473 files with the command above

Faheem Mitha

@DavidCarlisle The urls are a mile long for a start. The thing has no discernable structure. Why would you want to use it? It's like Facebook.

@egreg Oh, those are the ones I should use?

@egreg I see. The first u. Got it.

Joseph Wright

4:07 PM

@DavidCarlisle Not at present, but isn't that really superseded by the TDS-style zips

Faheem Mitha

@egreg are those the three different types of encoding? And I can use any one of them?

egreg

@FaheemMitha ?

Faheem Mitha

@egreg "OT1, T1 and U encoding". Quoting you from above.

And is T1 the best?

David Carlisle

@JosephWright well we have (had?) a lot of documentation saying that you could unpack stuff or get it unpacked...

egreg

@FaheemMitha Not really sure to understand. If you default encoding is T1 and you ask for \fontfamily{uni}\selectfont, then the Univers font in encoding T1 will be selected.

Faheem Mitha

4:14 PM

There is something called tug.dk/FontCatalogue.

@egreg Will this work for any font in TeX Live?

Actually, \fontfamily{uni}\selectfont is giving me an error here. Maybe the T1 version is not available?

egreg

@FaheemMitha The catalog specifies if the font is available in TeX Live (it may not be up-to-date, though).

David Carlisle

@JosephWright hmm seems like we got rid of most of that documentation (the old step by step install instructions) I suppose we could drop unpacked? team list I guess:-)

Faheem Mitha

@egreg ok

Joseph Wright

@DavidCarlisle Indeed

David Carlisle

@JosephWright although the links to docstrip in the readmes go to unpacked, and also if you wanted someone to get (just) latexrelease.sty to update an old setup, unpacked would be useful....

egreg

4:18 PM

@FaheemMitha Here's what the t1uni.fd file says:

\ProvidesFile{t1uni.fd}
        [1998/08/01 v2.0 Non Standard LaTeX font definitions]
\typeout{WARNING: universal font not avaliable in t1 definition.}
\typeout{WARNING: exiting, correct your source.}
\stop

@FaheemMitha ^^^^ seems clear

Faheem Mitha

@egreg So, you need to switch to U encoding locally?

egreg

@FaheemMitha No, to OT1. But note that the font is only available in bitmap form, not PostScript Type1.

\documentclass{article}
\usepackage[T1]{fontenc}
\begin{document}
Normal text and {\fontencoding{OT1}\fontfamily{uni}\selectfont Univers}
\end{document}

Faheem Mitha

@egreg ok

egreg

@FaheemMitha After seeing the result, ^^^^, I don't think I'll be using the font in my documents.

David Carlisle

@egreg typographic excellence, to your usual standards

Paulo Cereda

4:21 PM

@egreg It hurts, it hurts so much!

@DavidCarlisle LOL

Faheem Mitha

@egreg I don't know. It looks pleasantly old-fashioned.

David Carlisle

@FaheemMitha that's @egreg, the font just looks horrible.

Faheem Mitha

I want something that stands out in a letterhead. Maybe something with lots of whorls.

@DavidCarlisle Um, not really following. You mean @egreg is a typographical snob?

Or you mean the font sucks?

David Carlisle

@FaheemMitha No I meant he is pleasantly old-fashioned.

@FaheemMitha and that:-)

Faheem Mitha

@DavidCarlisle Good for him.

I don't think it is that bad. Though I'm not going to choose it for the letterhead.

Joseph Wright

4:27 PM

@DavidCarlisle I can upload something: just a question of taking the existing TDS zips and reworking

David Carlisle

@JosephWright yes or we delete it but if we delete it that should probably be a conscious decision, it's been that way a long time....

Faheem Mitha

Now trying urwchancal, but it's not cooperating.

{\fontencoding{OT1}\fontfamily{urwchancal}\selectfont doesn't work. Nor does

{\fontfamily{urwchancal}\selectfont

egreg

@FaheemMitha This font is just for calligraphic letters in math mode.

Joseph Wright

@DavidCarlisle CTAN nowadays avoid unpacked stuff, so that might not be a bad thing

Faheem Mitha

@egreg Only in math mode?

Ok.

Andrew Cashner

4:41 PM

@Faheem How about this? tex.stackexchange.com/questions/214184/…

If that isn't pleasantly old-fashioned, I don't know what is

*not a real suggestion* :)

Faheem Mitha

@AndrewCashner I'm a pleasantly old-fashioned kind of guy.

That might be a touch too old-fashioned for me, though.

Andrew Cashner

@Faheem Alegreya looks interesting, but not too interesting, at large sizes, which could be good for a letterhead. Depending on what you're going for.

Faheem Mitha

@AndrewCashner sample?

I was thinking of cursive thingys, but haven't found one I like.

Andrew Cashner

@Faheem tug.dk/FontCatalogue/alegreya

Faheem Mitha

@AndrewCashner hmm, not bad.

Andrew Cashner

4:49 PM

@Faheem Another interesting one, in a different way: tug.dk/FontCatalogue/librisadf

Faheem Mitha

Trying to try out tex gyre, but haven't found the right incantation.

The example usages are all to set it to default.

Ok, I had to look in the sty file to get it to work. I might go with tex gye's qzc.

What do you think, @AndrewCashner?

Andrew Cashner

@Faheem Is that Zapf Chancery?

Faheem Mitha

Sorry, tex gyre chorus.

tug.dk/FontCatalogue/tgchorus

Andrew Cashner

@Faheem Yeah, that's a copy of Herman Zapf's Chancery font. Could be nice, depends on how you use it, of course.

Faheem Mitha

I'm sorta looking for curly fonts. I think that is traditional, and I am just a slave to tradition.

@AndrewCashner Copy? I don't follow.

How does the original differ?

I've heard of Mr. Zapf. He's a famous designer.

Andrew Cashner

4:57 PM

@Faheem It's a clone of Zapf's font, like TeX Gyre Pagella is a clone of Zapf's Palatino. Zapf and Knuth worked closely together.

Faheem Mitha

@AndrewCashner Clone? So where is the original?

Andrew Cashner

@Faheem Have you looked at the other "old handwriting" fonts like these? tug.dk/FontCatalogue/uncialfonts.html

Faheem Mitha

@AndrewCashner no, I hadn't.

uncial fonts. I wonder what that means.

Andrew Cashner

@Faheem In blocks of iron type somewhere or something. Like Times Roman, Garamond, Baskerville, there are many pre-digital fonts that have spawned many copies.

Faheem Mitha

The tex gyre chorus looks quite good printed. I'll probably go with that. It looks boringly conventional, but what the hell...

Andrew Cashner

4:59 PM

@Faheem It was a style of medieval handwriting. Chancery was another style of handwriting. Modern lowercase is based on medieval uncial script.

Faheem Mitha

@AndrewCashner Oh. So wouldn't a better term be implementation? Since the original doesn't actually exist as digital type.

@AndrewCashner I see. You seem to know a lot about this.

I guess I should go and eat. It's late.

@AndrewCashner thank you for your help.

Andrew Cashner

@Faheem I'm just a dilettante. take care.

Faheem Mitha

Actually, those uncial fonts look positively stone age.

Or very early medieval.

Andrew Cashner

Yes, like 8th-10th century, based on even earlier Roman writing styles.

I think.

Faheem Mitha

@AndrewCashner yes, ancient monkish. Not really that appealing. I guess I could experiment a bit more.

Andrew Cashner

5:05 PM

@Faheem I would try Alegreya, italics, large. Its curvy but with some nice sharp corners too.

Faheem Mitha

@AndrewCashner Ok, I will. Thank you.

It's in TeX Live?

Andrew Cashner

yes

Faheem Mitha

@AndrewCashner ok

@wget without looking, your long line is in an l cell such cells never break over a line

wget

@DavidCarlisle The solution?

David Carlisle

@wget >{\hsize=\dimexpr2\hsize+2\tabcolsep\relax}X instead of l, problably

wget

@DavidCarlisle Where do I need to put that code? Instead of the l parameter?

Fonts galore -> 1001fonts.com

David Carlisle

@wget yes

Faheem Mitha

en.wikibooks.org/wiki/LaTeX/Fonts#Using_arbitrary_system_fonts talks about using something called the fontspec package. Is that good?

David Carlisle

@FaheemMitha it's needed to load fonts with lualatex or xelatex

Faheem Mitha

@DavidCarlisle Oh. So I would have to switch to one of these. Do they have any advantages font-wise?

I mean, using them.

David Carlisle

@FaheemMitha they use system fonts so there is a vastly larger set of fonts available

Faheem Mitha

6:03 PM

@DavidCarlisle Oh! But that is not the case for plain pdflatex, I guess.

wget

@DavidCarlisle I'm still fighting with the syntax. -->
\multicolumn{2}{>{\hsize=\dimexpr2\hsize+2\tabcolsep\relax}X}{Some very long line Some very long line Some very long line Some very long line Some very long line Some very long line Some very long line Some very long line Some very long line Some very long line }\\\bottomrule

Your syntax is still not compiling.

Faheem Mitha

@wget yikes, you're trying to do this against a deadline?

@DavidCarlisle can't he just use one of those p{} things?

wget

@FaheemMitha Nope I've sendtit as-it. And provide an errata afterwards ;-)

Faheem Mitha

@wget probably a wise choice. Debugging TeX formatting is bad enough. Debugging TeX formatting against a deadline doesn't bear thinking about.

@wget you could ask a question...

David Carlisle

6:20 PM

@wget looks OK to me (although I don't use tabu:-) That would work with the original tabularx X column

evinda

\begin{align*}
\section*{\texteAssignment Numerical Solution of Differential \\ \quad \quad \quad \quad Equation \\ First exercise }
Name: ....
\end{align*}

I wrote this but there is no space before Equation

What could I do?

Torbjørn T.

@evinda Not have a \section inside an align. Why have you done that?

Faheem Mitha

@evinda why are you putting a section inside an align?

evinda

@TorbjørnT. @FaheemMitha I did it like that in order that there is space before Equation.. How else could I do it?

Torbjørn T.

@evinda What exactly are you trying to do?

Faheem Mitha

6:32 PM

@evinda you can add space wherever you want. Maybe a MWE?

evinda

@TorbjørnT. I want that the word Equation appears at the middle of the second line..

@FaheemMitha I tried it with / / / / / / / / but it failed :/

Faheem Mitha

@evinda you could use \vspace{}, possibly. But I think you'll need to give an example. And maybe ask a question.

evinda

@FaheemMitha When I use \vspace{ Equation } then the word uatio appears :/

Torbjørn T.

@evinda So you want \section titles to be centered? Or just this one?

evinda

Only this one , because it doesn't fit at the first line @TorbjørnT.

Torbjørn T.

6:37 PM

@evinda \vspace{<length>} is for adding vertical space (e.g. \vspace{1cm}). Not what you're after here.

@evinda I'm not sure I fully understand what you're after. I'd recommend asking a question with a proper MWE, where you show what you have now, and explain what you want to achieve.

Faheem Mitha

@TorbjørnT. he/she wanted extra vertical space. As I understood it.

David Carlisle

@evinda avoid having explicit line breaks like \\ avoid having explicit space like \quad and don't put section headings inside math displays!

Torbjørn T.

@FaheemMitha \quad is horizontal space, centering implies horizontal space.

Faheem Mitha

@TorbjørnT. That's true. I misunderstood.

Anyway, I think an example is needed.

evinda

6:53 PM

@TorbjørnT. Ok, I used \vspace... Now it looks better... An other question.. How can I add a picture?

Faheem Mitha

@AndrewCashner actually, it looks like Debian has both something it calls the Zapf chancery as well as TeX Gyre Chorus. See

Q: Size of calligraphic number

I asked in this question Calligraphic numbers how to write a calligraphic number and got an answer. Now I need a notation for k-subsets and use the answer as follows: \documentclass[a4paper,11pt]{article} \usepackage[utf8]{inputenc} \usepackage{amsmath} \usepackage{xspace} %%% for caligrap...

typography calligraphy

% family qzc: Font TeX Gyre Chorus (package tgchorus)
% family pzc: Font Zapf Chancery (package chancery)

I don't know where the poster got his/her info from, but these are indistinguishable, at least to my eye.

Paulo Cereda

@FaheemMitha It's in TL.

Faheem Mitha

@PauloCereda what is?

Paulo Cereda

@FaheemMitha I think I quoted your comment.

Faheem Mitha

@PauloCereda perhaps, but I'm still not sure what "it" refers to.

Paulo Cereda

7:09 PM

@FaheemMitha Here:

[paulo@cambridge Downloads] $ grep "pzc" `kpsewhich chancery.sty`
\renewcommand{\rmdefault}{pzc}

evinda

I wrote at the beginning this:
\usepackage{graphicx}
\graphicspath{ {shm/} }

shm is the folder where I saved the picute that I want to upload and then this: \item \includegraphics{ask2}

(I called the graph ask2) but the picture doesn't appear... Have I written something wrong?

Faheem Mitha

@PauloCereda Right. And qzc appear to be that tex gyre chorus thingy.

Paulo Cereda

@FaheemMitha Yes:

[paulo@cambridge Downloads] $ grep "qzc" `kpsewhich tgchorus.sty`
  \xdef\qzc@scale{%
  \PackageInfo{tgchorus}{The qzc family is scaled by \qzc@scale}
\SetupKeyvalOptions{prefix=qzc@}
  \def\qzc@set@spacing{%
\renewcommand{\rmdefault}{qzc}

Faheem Mitha

@PauloCereda Ok. They appear to be effectively identical, but there may be subtle differences.

Possibly dumb questions - are such things as ligatures encoded into a font?

@PauloCereda I found this, for example.

Q: Zapf Chancery and placing a k next to a g

So, I was playing with fonts and found one really nice. It's just that I ran into trouble trying to write the word Background (quite a common word, eh?) using it. The k and the g extend into each other. And if I add space between them I have to add very much space indeed. (actually way too much) ...

fonts kerning

So, if you place a k and a g next to each other, you may see a difference. :-)

evinda

@FaheemMitha @PauloCereda @TorbjørnT. Do you have an idea?

Faheem Mitha

7:26 PM

@evinda If you want help debugging, I think you'll need to provide a complete self-contained example. I sugges asking a question.

suggest, sorry.
