Do we have a standard answer for bad uses of \text somewhere? Getting a bit tired repeating myself in various answers.

Hello.

@daleif depends what wrong features you want to highlight eg:

A: Why does \mathrm{\varphi} work, but \text{\varphi} does not?

Werner\varphi is a math symbol and requires math mode. Since \mathrm still "provides" math mode, \varphi doesn't complain. On the other hand, \text (from amstext; loaded by amsmath) is a macro that makes the correct choice in font size when switching to text mode - super convenient when typesetting tes...

@DavidCarlisle In this case I was needing it for $\text{X}_\text{Y}(\text{Z})$ IMO this was a rather bad suggestion.
 
@daleif yes that's the other issue \text picking up the prevailing text font as opposed to \mathrm using a fixed font (rather than the issue of \text not allowing math mode content) couldn't see a simple question just about that (hard to know what to search for)
 
@DavidCarlisle Might be an idea to make an overview question about \text. Wrong use of \text is on my top 3 of common LaTeX errors in the docs I deal with. So I react each time I see stuff like this. BTW: What is a good argument against users using _\text{Y} without braces. I think egreg or similar mentioned why it was bad at one time.
 
@daleif x_\mathrm{x} clearly breaks all latex syntax rules (the latex book doesn't even tell you that you can use x^2 without braces. It's unfortunate that it works but we can't change that now. practically speaking it fails in many tex to xx translators that are not using a full tex parse to work out the extent of the subscript. (eg x_\mbox{x} fails so you have to know a lot of the internal definition of the ams commands to know the braces can be dropped. Also even within tex many ...
@daleif ... packages want to make _ an active character reading its argument as #1 macro argument which would also fail as then x_\text{x} would be the same as x_{\text} {x}
 
12:17 PM
@DavidCarlisle My thought exactly, I was wondering whether lualatex might do things differently in this case.
 
@daleif no, currently it works same (even with unicode-math) but keeping it working is rather constraining really.
 
@DavidCarlisle that was another of my arguments against _\text no-one is guaranteeing that it will keep working.
 
Hi
when I do \showoutput
the log contain the information about the \write
but it use \ETC for long line
it is possible to set to print the fule line ?
 
12:34 PM
@samcarter LOL
 
1:17 PM
I try
\expandafter\wlog\expandafter{\input sncf.tex}
and I get
(/usr/local/texlive/2017/texmf-dist/tex/latex/base/size10.clo)) (./toto.aux)
! Undefined control sequence.
\GenericError ...
#4 \errhelp \@err@ ...
l.3 \expandafter\wlog\expandafter{\input sncf.tex}
any idea?
 
1:42 PM
@Maïeul You shoould use \@@input
 
2:06 PM
@Maïeul you can set these in texmf.cnf:
% It's probably inadvisable to change these. At any rate, we must have:
% 45 < error_line      < 255;
% 30 < half_error_line < error_line - 15;
% 60 <= max_print_line;
% These apply to TeX, Metafont, and MetaPost.
error_line = 79
half_error_line = 50
max_print_line = 79
 
yo'
Btw, have you noticed that @egreg was not capped one day recently?
 
SBM
emacs is so difficult to use
 
@SBM after a while it gets easier (I've been using it for 30 years) but you don't have to use it, use texmacs or texstudio or notepad or ....
@yo' all the more likely that I win the 654321 question on meta
 
SBM
@DavidCarlisle It appears to be highly configurable though, which is really nice.
 
@DavidCarlisle or... :)
 
2:20 PM
@yo' :-(
 
yo'
2:50 PM
@egreg you should be happy that so many people celebrate Christmas!

@yo' :-D

@JosephWright: Is there 'searching' problem within interface3.pdf? If I use Adobe Reader search for something \seq_new:N (for example) right from document start leads to "int Integer-valued count register" on top of page 3.
 
@ChristianHupfer With Atril (an Evince fork) everything is fine.
 
\documentclass{standalone}
\usepackage{tikzducks}
\begin{document}
\begin{tikzpicture}
\duck
\begin{scope}[xshift=-17.4em,yshift=37.5em,y=0.80pt, x=0.80pt, yscale=-3.5, xscale=3.5, inner sep=0pt, outer sep=0pt]
\path[draw=black,line join=miter,line cap=butt,line width=0.212pt]
    (75.7375,121.3037) -- (72.0960,125.6468);
  \path[draw=black,line join=miter,line cap=butt,line width=0.212pt]

  \path[draw=black,fill=black,line join=miter,line cap=butt,line width=0.212pt]
 
@TeXnician Well, it works for any PDF generated with pdftex etc. but not for interface3.pdf (Any means those I have tried ;-))
 
@ChristianHupfer Yes, but I just tested interface3.pdf with some examples.
 
@TeXnician Could you test the index and scroll page by page -- Adobe Reader seems to hang on the page for letters C and D

I am terrible with accessories
@samcarter ^^
 
@PauloCereda Is that a tie or ... oh no ... a .... bikini top ... naugthy duck :-P
 
@ChristianHupfer @JosephWright I saw this yesterday too. I can't search with adobe. No problem e.g. in sumatra. Also I can search in source3.pdf without problems.
 
@ChristianHupfer a very terrible drawing. :)
 
@ChristianHupfer Well, with Atril and Okular all works very well. Seems to be viewer-and-document related.
 
@UlrikeFischer Thanks -- I should look up in source3.pdf rather as reference ...
@TeXnician Yes, most likely. I had this once some weeks ago, until L3 packages etc. were updated and it worked, now it happens again (Adobe Reader is still the same, however)
 
4:57 PM
@PauloCereda It could be improved ;-).
 
@UlrikeFischer we might end up with \usepackage[rated=mature]{tikzducks} :)
 
@PauloCereda If you rate that for matures already, what if there is more stronger content? ;-)
 
@ChristianHupfer ooh you are being naughtier!
 
@PauloCereda tikz and violence ;-)
 
@PauloCereda A thong duck for the next TUG Meeting in Brazil?
 
5:05 PM
@CarLaTeX no, this duck is X-rated. :)
 
@PauloCereda Adults only duck?
 
@CarLaTeX :D
 
@ChristianHupfer, @UlrikeFischer There's nothing 'special' about the PDF ...
 
@PauloCereda That's what @samcarter thought of when she wrote about moral scruples!
 
@CarLaTeX oh no
@JosephWright I was going to say that I think corrupted a very strong word.
 
5:10 PM
@JosephWright But something doesn't work. E.g. if I search for "divis" the first hit is this:
 
@UlrikeFischer Sure, but what I mean is there is nothing special at the TeX end: I'm rebuilding locally to see if there is anything odd I can see
 
@PauloCereda :):):)
 
@UlrikeFischer I get to same position with Adobe Reader on Linux
 
5:29 PM
@JosephWright @ChristianHupfer I solved it. In the preferences of the adobe reader, in the search entry there is a cache setting, if one empties the cache the search works again (much slower at the first time ...).

@UlrikeFischer Yes, done it right now again and it works. Thank you very much!
 
6:01 PM
@UlrikeFischer Yup, works here too
@UlrikeFischer Might be worth recording somewhere: could you post a question and self-answer?
 
@CarLaTeX @PauloCereda I am suddenly very glad I added the clause about "moral scruples" :)
 
6:18 PM
@samcarter You should add the sexy duck to the package :):):)
 
@samcarter ooh
 
@PauloCereda You look great on that picture!

@StefanKottwitz oi it's not me!
@StefanKottwitz you naughty German!
@ChristianHupfer ^^
 
@StefanKottwitz LOL
 
DON'T YOU STAR THAT MESSAGE

6:28 PM
@PauloCereda I didn't make this naughty selfie.
 
<3
@StefanKottwitz we ducks are shy :)
 
@PauloCereda too late
 
@CarLaTeX oh no
 
@JosephWright done

@CarLaTeX done :)
 
@samcarter ooh the naked truth
 
@PauloCereda oiiiii
 
@samcarter soundtrack: youtube.com/watch?v=izGwDsrQ1eQ
@ChristianHupfer <3
 
@samcarter LOL
@PauloCereda g.co/kgs/TpDNQw is more suitable
 
@CarLaTeX Don't use URL shorteners, tex.co/u/101651
 
7:14 PM
@StefanKottwitz I'm on my smartphone, I didn't know what I did
 
@CarLaTeX It was a joke with a shortener (I usually didn't know what I did too)
 
@StefanKottwitz :):):)

@ChristianHupfer -- oh, my! the eyelashes are the crowning touch.
 
11:44 PM
We've had a bunch of extremely low quality posts today. I wonder whether this is all part of some Christmas hangover underway...?
 
@ChristianHupfer I was more talking about questions, but that one is also bad. Just flagged it. Aijajai.
 
@Werner Sometimes there is no difference...
