@Qrrbrbirlbel I added now extra spaces before important vars, it should look now better here -- does it?
 
Qrrbrbirlbel
Qrrbrbirlbel
Dammit, it's hard to search for \,, \(, … on TeX.SE!
 
hhh
hhh
@Qrrbrbirlbel Detexify for TeX.SE? :D
 
Qrrbrbirlbel
Qrrbrbirlbel
@hhh Yes for eq. (3). No to 1/A times u.
What about h_0, also in the third equation?
My thought is, that you can easily skip h_0 (and the like) while reading or it may be read as rooted.
@hhh And to annoy you furthermore: Don't use spaces before -!
 
hhh
hhh
@Qrrbrbirlbel You mean: "\$n'\$ -change"?
the space there or elsewhere?
 
Qrrbrbirlbel
Qrrbrbirlbel
Yes, and "State-function" and "matrix-case"
Especially "matrix-case", look how the second line is startet with a hyphen!

Interesting we have HK and CMH as avatars.

@Qrrbrbirlbel That is Finglish. In Finnish, they write like that "tila -funktio" meaning "state-function", I never realized a space -difference there :D ...victory found an odd difference

@JasperLoy My name experiences interesting variations here (Gonzola Medina or Mediana are the most common variants but someone used Gonzo Medina today/yesterday).
 
hhh
hhh
(I think the first is correct, I earlier always wrote it with a space)
(In Finnish, they write citations with a space.)
 
user19161
@GonzaloMedina I always think of speedy Gonzales. It's a cartoon character in case you have not watched it.
 
hhh
hhh
I think "he said so that..." -sentence is wrong (Finnish way, space there)

@JasperLoy hehe! ¡Ándale, ándale, ándale!

12:20 AM
Now is it in $\LaTeX$ with a space or without a space?
 
Qrrbrbirlbel
Qrrbrbirlbel
@hhh I'm German, we (I) love to use -, but in English I don' think you use any - there.
 
hhh
hhh
Ich denke "er ist ein..."-Satz aber weiss ich nicht ob...aber mit einem Space oder nicht?
 
Gonzalo Medina

@hhh González is a family name; Gonzalo is a first name, but they are related (as it's common in other languages), González meant "son of Gonzalo".

Space auf Deutsch? Raum? Oder nur Space?
 
Qrrbrbirlbel
Qrrbrbirlbel
12:23 AM
This space is called "Leerzeichen".
 
hhh
hhh
@Qrrbrbirlbel I haven't yet decided which I like to use, perhaps I stop using spaces there in $\LaTeX$ to avoid hypnation.
 
Qrrbrbirlbel
Qrrbrbirlbel
English typography dictates: No Space. And, as you can see, LaTeX doesn't like it, too.
 
hhh
hhh
@Qrrbrbirlbel Danke, ganz interessant -- ein muss englische Typographierung verstehen um $\LaTeX$ gut zu schreiben :)
 
Qrrbrbirlbel

@hhh If you want to write in Finnish, use the babel package with the option finnish.

@Qrrbrbirlbel Nein danke, Ich versuche mehr auf Deutsch zu schreiben ... Ich habe einen deutschen Tastatur schon gekauft :)
 
Qrrbrbirlbel

You can then use "- and "= for explicit hyphen signs. (Cf manual.)
 
hhh

...aber es gibt auch deutsch in babel -pkg?
oder heisst es "german" eigentlich, Ich denke so

Q: Setting the PATH so it applies to all users, including root/sudo

Joseph WrightThe instructions in How do I set PATH variables for all users on a server? work to set the PATH for all 'normal' users. However, if I do sudo -s and then printenv PATH the updated path is not shown. I've taken a look at for example Setting TeX Live path for root, but this does not seem to make se...

@JosephWright Also, if you use Ubuntu server, also consider changing to Debian.
 
user19161
Apologies to Ubuntu fans. I was once one too.

But one reason to use Ubuntu would be the longer support period. Ubuntu desktop and server now are supported for 5 years, the LTS releases that is.

@JosephWright It should, because it should parse /etc/environment

@ℝaphink Didn't seem to in my quick test (I added a 'marker' to /etc/environment)
 
egreg
egreg
12:50 PM
@JosephWright I'm not keen on /etc/environment for the TeX binary directory. This would solve the "root" path problem, but still sounds wrong to me. The root user should have a minimal path for maintenance purposes and adding to the path for it increases security risks; I mean "system security": the more programs you can access from root, the more risks to do wrong things. In my home made procedure I just add aliases for administrator users: 
alias mktexlsr='sudo /opt/texbin/mktexlsr'
alias updmap-sys='sudo /opt/texbin/updmap-sys'
alias fmtutil-sys='sudo /opt/texbin/fmtutil-sys'
where /opt/texbin is a soft link to the binary directory.
 
Joseph Wright
Joseph Wright
@egreg I guess it's because I come from a Windows background that I have a very different view of the path
 
egreg

Also a function for tlmgr: 
function sutlmgr () {
  if [[ -z "$@" ]]
  then
    sudo /opt/texbin/tlmgr -gui
  else
    sudo /opt/texbin/tlmgr "$@"
  fi
}
 
Joseph Wright

@topskip I've managed to acquire a copy of the TeX Gyre presentation from EuroTeX :-)
 
egreg

So if you simply call sutlmgr the GUI version is launched. If you specify command line parameters, the GUI is not called
 
Joseph Wright
Joseph Wright
@egreg I never run tlmgr graphically, so makes not so much difference to me :-)
 
egreg
egreg
12:55 PM
@JosephWright So just alias sutlmgr 'sudo /opt/texbin/tlmgr' is sufficient
The TeX Live programs all use kpathsea, so they are "path independent", once they are properly launched.
 
Joseph Wright
Joseph Wright
@egreg At present, I'm interested mainly as an intellectual exercise: my main working machines run other operating systems natively, and Linux is a guest both on my work PC and my own laptop
 
egreg
egreg
@JosephWright One of the reasons why I don't like /etc/environment is that if I try adding /opt/texbin (or the explicit path) to it on Fedora, the system stucks on login (at least this happened in one of my tests). Adding to /etc/profile.d is cleaner: you don't touch system files; removing texlive.sh is all you need for going back to the previous state.

@NativeSpeakersOfEnglish: I'm thinking a tag for questions about "random text generating" questions (like tex.stackexchange.com/questions/77654/…) would be good.

@DavidCarlisle Oh, latex3 will be nicer about EOLs?
I always want to indent and nice-ey my code, but I'm always afraid of screwing something up when I break things apart...
 
tohecz
tohecz
@Gnintendo indentation is never a problem, <newline><spaces&tabs> is always equal to <newline>, unless in whitespace-sensitive context (like verbatim, but I don't think you're rewriting the verbatim environment)
 
Gnintendo
Gnintendo
Right, indention isn't the issue; the problem is when I need to break-up something on one line to indent it.
Then, I get scared and add a % in a seemingly random spot. :s
(which is why I'm going to read up on those questions)
 
tohecz
tohecz
1:54 PM
@Gnintendo If you had no space in between before, you can safely add a percent-sign. If there was a space, you can leave it there and add percent-sign after the space.
 
egreg
egreg
@tohecz Or adding nothing at all if there's a space at the end
 
David Carlisle
David Carlisle
@Gnintendo all white space in code is ignored in l3 syntax. so you have to explicitly ask for it \typeout{hello world} produces helloworld It's actually relatively rare to need white space in code sections (and l3 defines ~ to produce a space token when you do need one) in the normal text part of the document eol being like a space is anyway what you expect.
 
tohecz
tohecz
@egreg yes, if there IS a space, you can put an end-of-line instead
 
David Carlisle
David Carlisle
@tohecz except when you can't
 
egreg
egreg
@Gnintendo Not that the "ignore spaces" feature is only in the programming environment of LaTeX3; in the document part it will be just the same as before.
 
tohecz
tohecz
2:02 PM
@DavidCarlisle There're always exceptions in LaTeX.
 
egreg
egreg
@tohecz The point is that <space><newline> and <space>%<newline> are usually equivalent. Not really if there is a single backslash before the space. So \<space><newline> will expand the macro \^^M, while \<space>%<newline> will execute the primitive \<space>. Of course LaTeX does \def\^^M{\ }
This in the common setting. Things get complicated if \endlinechar is given a new value. For instance, under \endlinechar=-1, \<space><newline> would execute the control sequence with "empty name".
This is because TeX strips off spaces that are at the end of the line and then inserts the endlinechar, which is usually ^^M with category code 5. 
\endlinechar=-1
\ %
\
\bye
If compiled with pdftex, this doesn't complain for the second line, while the third would give 
! Undefined control sequence.
l.3 \
Exercise Define the empty name control sequence so that it expands to \<space>
@DavidCarlisle What about recent cricket results? Too much TeX here.
 
tohecz
tohecz
@egreg \expandafter\let\csname\endcsname\ ?
sorry, you said expands:
\expandafter\def\csname\endcsname{\ }
 
egreg
egreg
@tohecz OK; if you want to \let it to \<space>, then 
\expandafter\let\csname\endcsname\ %
is the correct answer

@kan Hehe, you should have asked me but I was not here then. No need to trouble them with such trivialities.
 
kan
kan
@JasperLoy True, but I was desperate to get my tex system in place... I was also not very sane...
 
user19161
@kan You should now remove the Ubuntu TL since you don't need it anymore. And let me share with you a trick. Use sudo apt-get --no-install-recommends texmaker to install texmaker without Ubuntu TL dependencies.
 
kan
kan
@JasperLoy I already installed TeXmaker. I did not do any such thing....
Is that bad?
 
user19161
@kan Have you removed Ubuntu TL?
 
kan
kan
(And I think: it is good to have Ubuntu TL because Ubuntu won't complain about dependences... like math in Zim for instance)
 
user19161
4:47 PM
@kan OK, you can leave it there if you want. But if you do a fresh install the next time and just want to install texmaker without Ubuntu TL, use that command.
 
egreg
egreg
@kan It does no harm, so long as you have correctly set your path.
 
user19161
@kan Sorry, the command is sudo apt-get install --no-install-recommends texmaker.
 
user19161
Similarly for texworks if you use that instead.
 
kan
kan
@egreg Oh, but that's another war with ubuntu weaponry?
 
user19161
@kan Well, if you use texmaker you just need to select the right path in the editor.
 
user19161
4:51 PM
That is, specifically choose the executable to be the TUG TL and not the Ubuntu TL.
 
kan
kan
@JasperLoy It's already set some how!
 
user19161
@kan But are you sure it is the correct one?
 
user19161
It could be set to the wrong one and it still works!
 
kan
kan
@JasperLoy Heh, egreg asked me to check if the log file on compilation gave the right thingy....
And, it did.
 
user19161
@kan Ah OK, though if you know what you are doing there is no need to check, just set it!
 
egreg
egreg
4:54 PM
@JasperLoy The texlive-sh file that we suggested to install in /etc/profile.d ensures that /opt/texbin appears in the path before /usr/bin.
 
user19161
@egreg Hmm, I usually do it using easier methods!
 
egreg
egreg
@JasperLoy This one works; using /opt/texbin as a soft link to /usr/texlive/2012/bin/<arch> is good because you can simply redirect it when you install a new version. So you don't have to make changes to system files.
 
kan
kan
I think also, which tex gave the right answer.
/opt/texbin/tex
 
user19161
Hey guys, I got the mortarboard badge. HAHAHA!
 
egreg
egreg
@kan I took the idea from MacTeX; on a machine I have all versions of TeX Live from 2007 onwards. It's sufficient to relink /usr/texbin (and there's a widget to do it) for being able to use a different version.
@JasperLoy I too have it. :)
 
kan
kan
5:01 PM
@egreg oh, I see. I don't understand the nitty gritty, though.
 
egreg
egreg
@kan Let me state in another way. When TeX Live 2013 will be shipped out, you can avoid all the installation steps after ./install-tl doing simply two commands 
sudo rm /opt/texbin
sudo ln -s /usr/local/texlive/2013/bin/x86_64-linux /opt/texbin
 
kan
kan
@egreg Oh, so, I don't have to go through the entire process that we went through before! How nice. :) I think I follow this now...
 
egreg
egreg
@kan The fc-cache part will still be necessary, though. Then you can remove the 2012 tree when you're sure that the 2013 version doesn't break your current projects.
 
user19161
@kan I won't confuse you with my alternative method which is also simple. =)
 
kan
kan
More like: just append versions instead of update... am I right?
 
egreg
egreg
5:06 PM
@kan Until you've removed the 2012 tree, you can get back to it with the same two commands (with 2012 replacing 2013)
@JasperLoy I'm curious
 
kan
kan
@egreg OK. I'll make a note of these two commands! They certainly look very useful. :)

@AndrewStacey But the description sounds very complicated... Also, I am a newbie.
 
user19161
@egreg Well, I am the only user on my computer, so I install without sudo in my home folder in Debian under ~/texlive. Then I add PATH=~/texlive/bin/x86_64-linux:$PATH in my ~/.profile. After that copy the font config file to ~/.fonts.conf and then run fc-cache -fv to take care of xetex.

@egreg So, regarding our discussion on spaces and percents earlier, does than mean I need to add some percents to my titlepage code starting on line 117: github.com/Gnintendo/Art-History-Study-Guide/blob/master/…

I'd be carefull with such names. Try to add some random letter to the end of every parameter name like int& num_solutionW

@Gnintendo The braces around the whole thing are unnecessary; say \thispagestyle{empty} and load the emptypage package so that pages without text (such as those produced by \cleardoublepage or similar) have no header and footer. Don't use \` to do breaks between blocks: use an empty line. Then \fontsize{48}{48}\selectfont` and the opening brace should go before \fontsize as you do in lines 126-130
 
Gnintendo
Gnintendo
um
but the EOLs are OK?
@egreg do I not need to do something like: 
\fontsize{48}{48}{%
  \addfontfeature{Color=980000}%
  \char"E001 \char"E002%
}

@tohecz Hmm... I don't know. Sth is wrong. I'll probably fix it tommorrow. I am sleepy now. Thanks for your suggestion.
Tommorrow: Instiki in the pipeline.
Later folks. I am going to sleep.

@kan it's probably a stupid suggestion, well, I usually don't have problems with this since I append _ to every parameter

egreg
egreg
@Gnintendo This is wrong. Write 
{\fontsize{48}{48}\selectfont
\addfontfeature{Color=980000}%
\char"E001 \char"E002
}
 
Gnintendo
Gnintendo
5:53 PM
why do I need \selectfont?
and can I do:
{%
\fontsize{48}{48}\selectfont
\addfontfeature{Color=980000}%
\char"E001 \char"E002
}
 
egreg
egreg
@Gnintendo Because \fontsize by itself doesn't change the size. Perhaps \selectfont is done by \addfontfeature, but better being sure.
 
Gnintendo
Gnintendo
ok, and can I do what I just wrote?
 
egreg
egreg
Your version might introduce a space; it depends on the context
 
Gnintendo
Gnintendo
how about now? (I edited it?)
 
egreg
egreg
If you use \\ to separate blocks, it will add a space
 
Gnintendo
Gnintendo
5:56 PM
will it not introduce a space now?: 
{%
\fontsize{48}{48}\selectfont
\addfontfeature{Color=980000}%
\char"E001 \char"E002
}
 
egreg
egreg
@Gnintendo Now it's OK; but bear with me about \\
 
Gnintendo
Gnintendo
I'm working on it
@egreg Why don't I need a % after the last \char?
 
egreg
egreg
@Gnintendo Because \char expects a number after it; in these cases, a space after the number is ignored. The proper LaTeX syntax would be \symbol{"E002}
 
kan

@Andrew It looks like I will successfully be able to set up instiki. I am through to step 3... I'll let you know how it goes. I am holding on to this table gripped with fear. :(
 
Gnintendo
Gnintendo
@egreg but normally I would need a percent if I had text there, persay?
 
egreg
egreg
6:01 PM
@Gnintendo If you use \symbol{"E002} you need a %, for example. I'd add simply \par, in that case.
 
Gnintendo
Gnintendo
@egreg so, if I did something like "\today", then I wouldn't need a percent, but if I did "\today{}", then I WOULD need a %?
 
kan

@Andrew Done! :-) It was not that hard... I was probably reading something else.

@Gnintendo Here's a polished version

{\fontsize{48}{48}\selectfont

\MyTitle\par}

\vspace*{2cm}

{\fontsize{24}{24}\selectfont

\today

\vspace*{2cm}

{\fontsize{48}{48}\selectfont
\addfontfeature{Color=980000}
\symbol{E001}\symbol{"E002}\par}
\end{center}
\clearpage
\blankpageiftwoside
 
Gnintendo
Gnintendo
@egreg OK, cool, why don't you need a percent after {\fontsize{24}{24}\selectfont? Why doesn't that introduce a space?
Is it because of \selectfont?
 
egreg
egreg
6:06 PM
@Gnintendo Spaces after a multiletter control sequence are always ignored
 
Gnintendo
Gnintendo
even if they are contained in brackets?
eg \today{}?
err, yeah?
well uh, you get what I'm saying >.<
 
egreg
egreg
But you don't need a % after \addfontfeature{...} because you haven't started a paragraph, yet.
 
Gnintendo
Gnintendo
oh
 
egreg
egreg
@Gnintendo Why? You haven't a following text
 
Gnintendo
Gnintendo
oh :s
I must be off to class, back in a bit

6:08 PM
@Gnintendo Of course, a % after \addfontfeature{...} makes no harm

@egreg So will loading the emptypage package and doing \thispagestyle{empty} make the back of the page blank if I have a twoside document?
because currently I was having to program adding in that blank page
 
egreg
egreg
@Gnintendo Yes
 
Gnintendo
Gnintendo
@egreg and I have to load the emptypage package myself, are there any other packages that load it for me?
 
egreg
egreg
@Gnintendo \usepackage{emptypage} is what you need.
 
Gnintendo
Gnintendo
oh and it fixes my counter? O.o
@egreg What's the \clearpage doing; I saw somebody use it in this context so I added it, but what's its purpose?

@Gnintendo It ends a page.

and we're using \par to go back to vertical right?
 
egreg
egreg
@Gnintendo Yes
 
Gnintendo
Gnintendo
what's the point of the double \vfill?
I mean, rather, what's that actually doing?
 
egreg
egreg
@Gnintendo Oh, that? Nothing more than one \vfill alone, I believe. It would be different if you had other \vfill in the same title page.
 
Gnintendo
Gnintendo
@egreg and the \vfill itself?
 
egreg
egreg
8:00 PM
@Gnintendo It inserts vertical space to push the two halves to the top and bottom, IIRC your code.
 
Gnintendo

@egreg I wanted to make sure what it was practically doing for me is what it's actually doing for me, as that's not always the case

@egreg When I compile my document twoside, all the pages half the opposite alignment of what I want, eg, pushed to the left when it should be pushed right, or visa versa
is there any way to fix that?
or maybe I'm crazy

@Gnintendo The outer margins are larger, so odd pages have larger right margin.
 
egreg
egreg
@TorbjørnT. +1
 
David Carlisle
David Carlisle
@Gnintendo latex has separate oddsidemargin and evensidemargin settings or higher level packages like geometry simplify it
@Gnintendo margins are for thumbs to hold the page not space to lose in the binding
 
Gnintendo
Gnintendo
@DavidCarlisle They just seem awfully big by default then

Q: Why are default LaTeX margins so big?

Jeremy I've read that—unless I know a lot about typesetting—I shouldn't change the margins of a LaTeX document. The default margin size of the article class is really big and it feels like a lot of space is waste. Thanks to the geometry package, it is simple to change the margins, but I'm not sure if I ...

8:32 PM
My twosided document is meant to be put in 3-ringed binding, I understand the 3-margins-same thing, but won't the addition of the binding just make it seem awkwardly close to the binding? Am I crazy?
 
David Carlisle
David Carlisle
8:49 PM
@Gnintendo the default margins are based on usable page size, if you are using ring binding or otherwise losing part of the page in the binding process then the default margins are not suitable, just as if it were going to a classical book binding process where they cut through all the pages.
@Gnintendo despite any answer given to the first part, the answer to the last part might be "yes"
 
Gnintendo
Gnintendo
hehe
How should I go about double spacing my document? I'm seeing several ways when I google, is the setspace package the best way to go?
 
Joseph Wright
Joseph Wright
@DavidCarlisle Yeah, I know about that. What's needed is a proper solution at the kernel level, I guess (to have proper expansion-context switching)
 
David Carlisle
David Carlisle
@Gnintendo best answer is don't do it, but otherwise yes probably setspace has over the years collected as many hacks as possible to make it half work.
 
egreg
egreg
@Gnintendo Simple: don't double space your documents; it's only a waste of paper.
 
David Carlisle
David Carlisle
@JosephWright Just a small hint from one package author to another: you knowing about it doesn't make it a documented feature.

Why isn't it politically correct? The white space is much more than the black letters.

9:00 PM
@Gnintendo Ask him why. Double spacing looks ugly too.
 
David Carlisle
David Carlisle
@Gnintendo alternatively look for published books in your subject area and see if any commercially edited ones really have spaced out lines. If they want double space for scribbling comments on drafts, that is another matter but for proof reading the text spacing and margins don't have to be final
 
Joseph Wright
Joseph Wright
@DavidCarlisle Ah, not quite what I meant. The known issue is that I have to globally define things thing \GeV to prevent Undefined control sequence errors in general, as hyperref will \protected@edef stuff after some set up. Ideally, in such a context there would be a hook such that all 'document commands' protected their arguments.

Real anecdote: at a conference the speaker was talking about some part of abstract algebra; he classified his objects as "red" and "black", just to give some names. Unfortunately the "red" objects had worse properties than the "black" ones and a lady mathematician was very upset about this.
She had been for a long time a member of the British Communist party. :)

@DavidCarlisle I'm also not really sure that expansion of such sectional material is needed at all, but know insufficient detail about TOC construction to be sure
 
David Carlisle
David Carlisle
@JosephWright not really needed looking at the code xr-hyper is just trying to add the linking, it could just expand once and expandafter in the needed tokens but I think in a 2e setting \protected@edef ought to be safe as all the tokens have already been through the protected@erite to the aux file so they should be expansion-context robust. (Didn't look how siunitx got an undefined command there:-)

@DavidCarlisle Probably a timing issue: to avoid overwriting stuff I only set up the definitions of units to deal with expansion issues at the start of the document.

Hey after LaTeX 3 comes out, will the next version be LaTeX 4 or LaTeX 3.x?

Duck universe
The Duck universe (also called the Donald Duck universe or Scrooge McDuck universe) is a fictional universe where Disney cartoon characters Donald Duck and Scrooge McDuck live. It is a spin off of the older Mickey Mouse universe, yet has become much more extensive. "Duck universe" is a term used by fans and is not an official part of the Disney lexicon. The world's continuity has been primarily built in comics by Carl Barks (1901-2000), but has its roots in the Donald Duck short film series and the Silly Symphony comic strip by Ted Osborne and Al Taliaferro. Other cartoonists have built ...
