@barbarabeeton I already tried that and it's not the issue. Somehow a spacing is messing the whole slide, or the frametitle definition is not captured for \AtBeginDocument
is it possible to assign text to some \def, but use the variable inside verbatim? I know ofcourse that verbatim accepts things, well, verbatim, but I am asking if there is a trick to do it. Here is what I mean:
\documentclass{article}
\usepackage{cprotect}
\usepackage{xparse}
\begin{document}
\def\myVerbatimText {
This is some text, which can contain
$\sin(x)$ or code or anything
but it has to be passed verbatim such as
plot(0:10,sin(0:10));
}
\texttt{\myVerbatimText}%this works, but really what I want
\begin{verbatim}%this does not work, ofcourse!
\myVerbatimText
\end{verbatim}
\end{document}
The reason is, I'd like to assign some verbatim to a variable, then use that variable \myVerbatimText instead.
@egreg That is true, but the main problem was that ExplSyntaxOff resets catcode changes. I tried several permutations of activation of characters before.
@HenriMenke It makes sense: ^ may be used by packages in its special meaning in contexts like ^^J, which wouldn't work if ^ doesn't have category code 7.
@JosephWright What could probably be done is adding some boilerplate for a character activator, i.e. \char_set_catcode_activator:nN { `\^ } \makecaretactive. Or maybe something like \startmakeactive ... \stopmakeactive, which simply makes all characters in the list of active characters active.
@JosephWright Don't give it too much thought. Actually, I don't really have a use case. I guess such a thing should belong in a future user interface, not in the programming interface.
@HenriMenke The plan is really to have a fixed set of active chars (variable active char lists are a real pain), though there are some interesting solutions (hence pinging @DavidCarlisle)
My focus here is on the should in the sentence fragment "I should very much like...". Why is it there in place of would? It seems strange that should is used in the subjunctive mood there -- is it grammatical? If the fragment is idiomatic, can anyone explain the history of the idiom?
@JosephWright Sorry, someone came to the door. No, I'm not often here; I tend to hang out on the LaTeX subreddit as more suited to my skill level. :-) Nice to see you this morning.
@PauloCereda Something interesting about Portuguese on ELU.SE:
Absolutely fantastic answer. Also, for someone wanting to hear the difference between syllable and stress timing within a language, compare Brazilian Portuguese (strongly stress timed) and European Portuguese (strongly syllable timed). — guifa2 days ago
@PauloCereda a translation could be "Hello, very good, potatoes, do not what thank you fetch the cow"
@PauloCereda even in english it's not perfect :P
@yo' or "allez chercher". "Venez" will be suitable if you ask someone to come and take the cow (by phone for example). "Allez" is more go to take the cow that are in a specific place
No way a post saying "IQ of obsidian" is acceptable here. — yo'18 mins ago
@PauloCereda There is no linguistic definition of 'a language'; they are social constructions. But I would say that they are different languages, although with a lot of mutual intelligibility. And spoken Brazilian Portuguese is really markedly different from the written standard.
I'm currently writing a large document of notes on convex analysis. I'm currently using times, because I like the way it looks. But what I'm wondering is:
Can you think of compelling reasons to use any specific font?
Of course I would like things to look pretty, but my first priority is for th...
@AlanMunn -- i like this too, especially that a car could be stationary before it struck a tree. (i actually did have a collision between my stationary car and a tree, but it was the tree falling on the car.)
@AlanMunn -- no, fortunately. i spotted the result from a window across the street. and also fortunately, the tree (though quite large) was in full leaf and very springy, and i was able to crawl under, get in the car, and drive away with only a few minor scratches. (david carlisle's recent tree+car incident was a bit more problematic.)
@barbarabeeton Wow. Did it come down in a storm? We live in a neighbourhood with lots of very old trees, and every storm is a bit of a nailbiting experience.
@AlanMunn -- yes, it was in a storm, though not a serious storm. a few years ago, a tree in front of our house fell down in a storm, but it was very well behaved. when standing, the tree was next to the street, with power and phone lines just on the other side. when it fell, it fell exactly parallel to the curb, neither taking down the power lines nor blocking the street. couldn't have planned it better!
Is there a trick to assign text to variable, and expand that variable to use with verbatim environemnt? As in
\documentclass{article}
\begin{document}
\def\myVerbatimText {
This is some text, which can contain
$\sin(x)$ or code or anything
but it has to be passed verbatim such as
plot(0:10,sin(0:10));
}
\begin{verbatim}%this does not work, ofcourse!
\myVerbatimText
\end{verbatim}
\end{document}
@DavidCarlisle I want the final result to show as if I have typed the text block by hand, inside verbatim. i.e. if I have some text, what ever it is, to put in few places in the document, as verbatim. I do not want to type it again and again. I want to put it in variable, and then use the variable. Even when inside verbatim environment.
@DavidCarlisle in normal text, it is no problem. Latex will expand it as is. So it is no problem there. But I can't use \var inside verbatim. It will not expand ofcourse. I want it to expand, even if inside verbatim. In Perl, this is called interpolated raw text. In Perl, if I type $A inside string, then perl will replace A by its value first, even when inside raw string.
@Nasser no. the natural way to make what you ask for above is to use some \verbdef command that defines \myVerbatimText to be the verbatim text, but then if you use it, it will be like the v argument of xparse it will always be a sequence of character tokens not commands to be exeuted.
@DavidCarlisle I looked at xparse, I understand it only do single lines. as in \verb. It does not handle multilines verbatim with "v"
@DavidCarlisle I meant the idea. Not the implementation. If there is special code, which verbatim detect, as special, it will work. In perl, it is the "$".
@Nasser single/multiple lines is a side issue the question is what do you want to save in \myVerbatimText if the argument is {$\sin(x)$) do you want to save the 6 tokens, math-start,sin,(,x,),math-start(again:-), in which case it is easy to execute it to produce sin x but hard to use in verbatim, or do you want to save the 9 tokens, $-character, \-character, s,i,n,(,x,),$-character in which case it is easy to use in verbatim but tricker to execute as commands.
@DavidCarlisle I want the same text to remain as is, verbatim. So if I type \def\x{$sin(x)$} and then do \verb| \x | then I want the result as if I had typeed \verb| $sin(x)$ |
@Nasser Nasser but if you go \def\x{\sin} then normally x stores a single token but in a verbatim context the scanning rules are changed so \sin is four tokens \-s-i-n that is why verbatim makes it appear as \sin (it also does some other tings like font changes not relevant here) so if you want the same code used as verbatim and not verbatim there are two ways you can go (with different constraints and side effects) you can store the token \sin and in verbatim like contexts ..
@yo' it will always be replaced by its value. as if I had typed $\sin(x)$ there. So it will be as if I typed \section{ $\sin(x)$ } and in verbatim, the same thing, as if I typed \verb| $\sin(x)$ |. Everywhere where I type \x I want it to be replaced by wheverver its value was.
@Nasser try to generate an equivalent string of characters for that token. or you can store the verbatim characters and then if you want to execute it you can use (usually) use the etex \scantokens primitive to re-evaluate the sequence of character tokens as if it were an input string
@Nasser ^^ See, I have \x and \y, both show the contents $\sin (x)$, but as you can check, each of them behaves quite differently. The question is, which one do you want.
@yo' actually he doesn't mind which, but wants to generate the other. ie start from \x and get \y or start from \y and get \x, without typing sin(x) twice
@Nasser but I thought all your documents were generated from mathematica etc? in which case just typing the stuff twice is simpler:-)
@yo' I see. I want the second one please, the Y. I want to assign literal text to a variable, tell latex not to expand it or anything when I assign it to variable (ok macro). Then I want to replace the content of the variable any where in the document. Like your Y . I did not know about edef before. WIll look at it.

@Nasser well no matter what language it's trivial to get perl to write out $\sin(x)$ \verb|$\sin(x)$| so why worry about TeX contortions required to get tex to do it?
I am learning to use LaTeX from lshort.pdf.
I am using a Debian 8.3 system with texlive package installed.

@DavidCarlisle the problem with using perl to generate latex, is that if I get an error, I have to trace back from Latex document back to perl to locate the place where the error came from.
Oh, ok,. I did not know \show gave the error. I am using this in texstudio and just saw process exited with error message and nothing else. ok.
@Nasser it's not an error it just has the same user interface it stops, shows you the meaning of the command, and then offers the ? prompt so if you hit return you can carry on
Here is my perl function to add longtable:
sub start_table{
my ($w,$p,$sep,@others) = @_;
my $y = 1-$w;
<<"END_MSG";
\\begin{longtable}[t]{|$p\{$w\\textwidth-2\\tabcolsep-.6pt}
$sep
$p\{$y\\textwidth-2\\tabcolsep-.6pt}|
}\\hline\\endfirsthead
END_MSG
}
Here is how I call it
start_table(0.45,'m','|');
It all works well. Much easier than using Latex and lua, where the interface is so hard to manage. But only issue, is that hard to find errors when it happens, since I have now 2 files instead of one.
@DavidCarlisle in texstudio., there is no carriage return to hit. It just says error. I need to run this from linux command line to see it and be able to hit carriage return. That is why I thought it was error.
@DavidCarlisle yes. I am using perl now to generate latex. I would have liked to use latex and lua to do all of this instead. By trivial things to do in perl, seems like brain surgery in Latex.
@Nasser no latex is I would say considerably simpler than perl as a language it's just one that you are less familiar with. the discussion above about verbatim or not in tex isn't that different from asking why you need \\ not \ in the above perl tex strings, it's just about controlling the interpretation order
@DavidCarlisle Yes. Perl has two types of strings. Interpolated (one with ") and non-interpolated (one with '). Sometimes I use " and sometimes I use ' depending on need. This could all be done in lua code inside Latex, but passing things between Latex and lua is not easy. I find just doing the whole Latex generation from perl easier, even though debugging latex error becomes harder, since now I have to fix perl script and go back to latex each time.
But last night, in 30 minutes I was able to do in perl what I struggled all day trying to do in lua inside Latex.
@Canageek probably(although paths always entertaining to set up) I've used cygwin for everything for so long it's hard to remember. I also have a native windows emacs but i never really use any shell mode features in that as it uses the windows command interpreter which I never understand. what goes wrong?
@JosephWright I know it's been around a while, but if it's still being updated then it would make sense to update also for those things. Considering also it being the second highest voted answer in the learning resources question here (tex.stackexchange.com/a/583/586)
@Canageek it used to put stuff on the kill ring as well as the system clipboard but they changed the defaults a while (years?) back so by default they are separate
@Canageek tex I get from tug so I'm running tl2016 pretest at the moment (and latex sources I er have the sources here oddly enough so they are up to date) no idea how recent gnuplot is cygwin gives me... gnuplot 5.0 patchlevel 0 (is that current?) best of all, for @PauloCereda bash: vim: command not found
@Canageek cygwin is supported texlive platform so it's current (in fact to be be able to test luatex before the pretest I was building texlive from source, it just works with configure; make

@Canageek everything works well except arara because there isn't a useable cygwin java as far as I can tell, so I use the native windows java but that means it doesn't understand the cygwin paths without too much effort. I blame @PauloCereda
I hate it when emacs decides it knows better then me how many tabs I need
And decides that amount is 0
Is there a package to give emacs decent bracket highlighting?
@DavidCarlisle You use emacs, right? Can you explain emacs tab key to me? I've never figured it out. Sometimes it works like it should. Sometimes it goes backwards. Sometimes it does nothing at all and I have to ram on the spacebar for a while.
@Canageek If in doubt use C-h k <tab> in most modes it indents the current line according to the language mode in place so it doesn't insert a tab but will move the current line left or right according to the relative indent specified for that construct and the indent of the line above so basically like doing M-x indent-region with the region being one line
My focus here is on the should in the sentence fragment "I should very much like...". Why is it there in place of would? It seems strange that should is used in the subjunctive mood there -- is it grammatical? If the fragment is idiomatic, can anyone explain the history of the idiom?
