@AlanMunn I'd still be interested in seeing what a recent Acrobat Pro gives for a low level PDF analysis for the MWE at github.com/pgf-tikz/pgf/issues/824. Otherwise, I need to keep trying to figure out what is wrong with the file I'm sending to my printer. Thanks for being willing to look at it!

\DeclareFixedFont{\ttm}{T1}{txtt}{m}{n}{12}

what are options for declarefixedfont?

I know \ttm is a font family, and 12 is the font size

what are the rest

I have a little macro that consumes a list of things and produces something else, a tikz path, and I want to do now (using tikz) something like «\draw \myMacro{x,y,q,x,a,y};»

How exactly can I do that?
My original plan was something like «\edef\tmp{\myMacro{blah}}\draw\edef;» but the problem is that as \myMacro eats the list it keeps a state stored using \def's, and that is nonexandable, so \edef does not do anything...

FWIW, the code is


    \makeatletter
    \def\process#1{%
      \def\s@last{x}
      (0,0)
      \s@go#1
    }
    \def\s@go#1#2{
      node {$#1$}
      \let\s@next\s@go
      \if#2u
        \if#2\s@last ++(0,1)\else++(1,1)\fi
      \else\if#2d
        \if#2\s@last ++(0,-1)\else++(1,-1)\fi
      \else
        \let\s@next\relax
      \fi\fi
      \def\s@last{#2}
      \s@next
    }
    \makeatother

and the call I'd like to make is «\draw \process{1u2u3u4d5d6d7x};»

Adding the state as an argument (monads FTW!) one gets the following:
    \makeatletter
    \def\process#1{%
      (0,0)
      \s@go s#1
    }
    \def\s@done#1{;}
    \def\s@go#1#2#3{
      node {$#2$}
      \let\s@next\s@go
      \if#3u
        ++\if#3#1 (0,1)\else(1,1)\fi
      \else\if#3d
        ++\if#3#1 (0,-1)\else(1,-1)\fi
      \else\if#3x
        \let\s@next\s@done
      \fi\fi\fi
      \s@next#3
    }
    \makeatother

Still, I don't know how to pass this to tikz's \draw :-/

@EnthusiasticEngineer no \ttm is the arbitrary name that you define on that line then txtt if the family m the series n is the shape so it's just a shorthand for \fontencoding{T1}\fontfamily{txtt}\fontseries{m}\fontshape{n}\fontsize{12}{\baselineskip}\selectfont

this question deserves more than a couple of votes, it's not every day someone finds a bug in tex the program:-)

Q: How to interpret ``underfull'' warnings in alignment?

I'm trying to figure out why there are warnings for 125pt case of AT&T table example in TeXbook. While trying to understand the meaning of these warnings, I came across p.302 of TeXbook, that says: For example, suppose you say ‘\tabskip=0pt plus10pt \halign to200pt{&#\hfil\cr...\cr}’, and ...

Paulo Cereda

@DavidCarlisle voted :)

@DavidCarlisle meanwhile, zero bugs in your packages. :)

David Carlisle

@PauloCereda naturally

Paulo Cereda

@DavidCarlisle ooh

oh sorry I missed your earlier comment @PauloCereda

@PauloCereda dinner

Paulo Cereda

@DavidCarlisle oh no

@DavidCarlisle It doesn't work. I get postscript errors (both with texlive and miktex). Does it work for you?

Error: /undefined in defproduct

@egreg I've made a start on the renames: going to take a while as there are a lot, and I don't want to over-do it

Enthusiastic Engineer

@DavidCarlisle that baselineskip is what I was looking for! thank you :-)

@DavidCarlisle up-voted both the bug finder and bug killer!

I like the comments on contributors to this site:

tex-talk.net/contributors

David Carlisle

@UlrikeFischer oh I posted the version without that fixed? there should be no % after the def on the previous line, let me check the version in the answer

@UlrikeFischer I think the one in the answer should be OK, in the comment above I only posted the test but in the answer I also deleted a % from the previous line.

@EnthusiasticEngineer it doesn't actually set the baselineskip to baselineskip in that way (it just doesn't touch the baseline setting at all) but there isn't a user level command to set the font size that doesn't have a second argument so that's the easiest way to think of it

@AkiraKakuto thanks for looking at the hyperref patch:-)

Paulo Cereda

TeXplate is out, yay!

Enthusiastic Engineer

@DavidCarlisle I used it with a code to set paragraph density at it did not work... listing is tough in working with bold font and setting paragraph parameters... did it with some other codes instead

@egreg See edits :)

Of course, as soon as one starts updating answers to adjust for one change, you spot other things to fix ...

@DavidCarlisle Could you find out where does the error come from?

GermanShepherd

Hi people, Long ago, there was a query on the forum on drawing funny/beautiful "last"slides of beamer presentation, instead of the regular "thank you"slide. If I remember right, it had answers on drawing the Looney Toons "That's all folks" logo, MGM's lion and so on. I tried searching on the main site, but couldnt find the question. By any chance, is it deleted?

Paulo Cereda

@GermanShepherd I really don't seem to recall a question like this... but it might be simply a background image with some text over it...

GermanShepherd

@PauloCereda Do you have any funny last slide ideas? for a semi-formal talk to engineers

Paulo Cereda

@GermanShepherd let me check. :)

Phelype Oleinik

@GermanShepherd This one? tex.stackexchange.com/a/479743/134574

GermanShepherd

11:26 AM

@PhelypeOleinik Yes :) cant thank you enough!

How exactly did you find it? I tried searching for fun,beamer, tikz..

Phelype Oleinik

@GermanShepherd I Googled “looney tunes site:tex.stackexchange.com”

@GermanShepherd Third result for me

GermanShepherd

@PhelypeOleinik that explains it.. I searched only in the site. Thanks again!

@PauloCereda I still want to know your answer though ;)

Phelype Oleinik

@GermanShepherd You're welcome :-) I somehow can't properly use the site's search mechanism... Google still works best for me

Paulo Cereda

@GermanShepherd well, the only funny thing I found was "thank you very much" written in Latin for a keynote about Gregorian chants... :)

David Carlisle

@PhelypeOleinik see Igor's comment under my answer, looks like it just fails to set the subclass of the glue node

GermanShepherd

11:32 AM

@PhelypeOleinik :)

@PauloCereda oh..thats a good one! :)

Phelype Oleinik

@DavidCarlisle Oh, there! That day I got stuck looking at the loop in @<Scan the preamble...@>, because it does @<Append the current tabskip glue...@> once for each preamble column, so one \tabskip is missing in that part. Though it doesn't make much sense, after all the final \tabskip is added...

@DavidCarlisle This Igor guy is really committed into learning TeX :-)

Enthusiastic Engineer

@GermanShepherd nice idea :-)

David Carlisle

@PhelypeOleinik yep:-)

Enthusiastic Engineer

I am just polishing my research papers and reports to send them for my professor and I am nervous I may have no-needed white space or extra useless packages! :(((

David Carlisle

@EnthusiasticEngineer it is of course more important to get the white space right than the results of your research, the results don't matter so long as they are typeset nicely.
