Hello all!
@egreg 1) I would like to know what program or how did you do for paste this "First first LaTeX document" image into a beamer document (taken from your course: profs.scienze.univr.it/~gregorio/corso-latex.pdf, slide 88)
@egreg 2) and I would to know how you have managed to increase and place in what appears to be a geometric arrangement (looking at the sides) the next 2 images of the same document, slides 89 and 90
Thank you so much!

hi, which package should we call in order to use symbols in The Comprehensive LATEX Symbol List
 
8:49 AM
@UlrikeFischer ooh
@CarLaTeX yay
 
@EnthusiasticEngineer The packages are indicated in the document. For example, to get a hand with an index that indicates a direction, you can use the dingbat package and the \leftpointright command as indicated on page 132 or the bbding package with the \HandRight command
\documentclass{article}
\usepackage{bbding}
\usepackage{dingbat}
\begin{document}
\HandRight

\leftpointright
\end{document}

Weird, \includegraphics{g2sebevrazdy.jpg} that previously worked doesn't any more. The file cannot be found according to LuaLaTeX but it is there.
 
@wilx As always, MWE and a log file please ...
 
@JosephWright ooh Microsoft Web Expression
 
MWE is always a problem. :) But I will try.
 
@UlrikeFischer I see.
 
9:49 AM
@manooooh I made an auxiliary file, compiled it and used \includegraphics.
 
Using the \let\quote@name\unquote@name workaround works.
 
Watching the debate in the House of Lords is boring. Commons is way more amusing.
 
@wilx This spaces and dots business is quite a pain. << @DavidCarlisle

@AndréC thank you ^_^
 
@UlrikeFischer I think I have a plan but not sure how much time I have next few days
 
wow... @DavidCarlisle you wrote this document... I am proud of you.

@DavidCarlisle In view of the discussion about pdffilesize etc I'm starting to wonder how many slightly different variants there are ...
 
 
1 hour later…
1:02 PM
@UlrikeFischer See my check-in
 
@JosephWright where?
@JosephWright latex3?
 
@UlrikeFischer Yes
 
@JosephWright what happens with filenames with a space directly before the extension? e.g. space .png. Will then \includegraphics{space .png} work but \includegraphics{space } not?
 
1:18 PM
@UlrikeFischer At present they act differently; @DavidCarlisle points out that this is already a similar case with the input path
 
@JosephWright I don't mind it much - people adding spaces there get what they deserve ;-). We should simply request that there should be no spaces at the begin, the end and around dots ...

@EnthusiasticEngineer -- The Comprehensive Symbols List was written by Scott Pakin, not @DavidCarlisle. But yes, it is an amazing and useful document.
 
3:56 PM
@JosephWright I can now run checks for pdfsyntax on the command line - that's really nice ;-)
 
4:50 PM
@UlrikeFischer Hope it's OK for you now ... I've tightened up a bit
 
@JosephWright you mean the file extension/space?
 
@UlrikeFischer Yes
 
5:09 PM
@JosephWright looks ok imho (but I didn't run tests).
 
5:57 PM
@UlrikeFischer If you, @DavidCarlisle and perhaps @egreg look over the change, I'll probably release: we are sweeping up various bugs at the present, and it's good to stay on top of those
 
6:11 PM
@JosephWright I may look but I'm at Mum's until Tuesday so only sporadically online
 
@DavidCarlisle Ah, got it
 
 
2 hours later…
7:43 PM
@DavidCarlisle Got things going with the build business ...
 
8:31 PM
@UlrikeFischer I have \pdfmajorversion working for the basic idea of 'this PDF': need to work on the PDF-inclusion code (C ...)
 
@JosephWright ;-)
 
@UlrikeFischer See mail to TL list
@UlrikeFischer Works here on WSL, at least in a demo file:
\documentclass{article}
\pdfmajorversion=2
\pdfminorversion=0
\pdfcompresslevel=0
\begin{document}
Hello world

I've not looked at how it interacts with \pdfminorversion
 
@JosephWright looks good. I wished I could test, but I don't have the space for WSL ;-(
 
@UlrikeFischer I could do with a bigger HD, I have to say ...
 
@JosephWright I think you have a typo in the patch code: help2 ("The pdfminorversion must be 1 or 2.")@/. I think it should be pdfmajorversion there
 
8:43 PM
@PhelypeOleinik Ooops, I'll fix
 
@JosephWright why restrict to 1 or 2?
 
@DavidCarlisle I just tried with luatex and it doesn't allow 3 either.
 
@DavidCarlisle Seems reasonable given the speed of PDF development: we will have a lot more than a year if we need to alter
 
@JosephWright that's the thinking that lead to the current problem, that it was Ok to hardwire major version=1, problem is not that it will change in a year more that it may change in 10 and it will be hard to track down all the places that need changing.
 
@DavidCarlisle I get that: feel free to critic on the TL list ;)
 
8:47 PM
@JosephWright ok:-)
 
@DavidCarlisle More tricky is the fact that PDF major version isn't passed at all to the C
@DavidCarlisle Grinding slowly with C ... this is going to be hard
 
@JosephWright are you pushing back to gh? (I could sync my checkout with your branch if you wanted an extra tester)
 
@DavidCarlisle Er, I can do: I'll probably be rebasing and the like
@DavidCarlisle Give me ... a minute or so
 
@JosephWright as I say I'm probably not going to do anything for a day or two so no rush
 
@DavidCarlisle OK, let me get a few more things done
@DavidCarlisle I'm learning C the hard way ...
 
8:57 PM
@JosephWright if I have a branch that is just tracking you as a remote and I don't try to merge with my master branch then it should be relatively stress free to keep in sync even if you rebase force/push etc
@JosephWright tex is more fun
 
@DavidCarlisle Yes: what's all this static and .h file business ...
 
@JosephWright .h are the cpp pre-processor header files, they really are like tex:-)
$ grep pdf.*minor *.c? | wc -l
41
 
@JosephWright ^^ ouch pdf minor version is used all over including files derived from poppler, I wonder if the upstream poppler code has already been updated...
 
@DavidCarlisle Perhaps ...
 
9:00 PM
@JosephWright thanks
 
@DavidCarlisle Except you have one place to say the arguments, another to then set up the function ... it's weird
@DavidCarlisle Yes, I know!!
@DavidCarlisle I'm doing pdftex.web and files that it uses ... follow the commits ;)
 
@JosephWright yes I was just looking what was in texk/web2c/pdftexdir
 
@DavidCarlisle Ah, right
@DavidCarlisle I think I said on the TL list a while ago that this could be tricky tricky work
@DavidCarlisle Can you see where read_image() is defined? I see it used in pdftex.web but ... I don't know where it comes from!
@DavidCarlisle Ah, it's readimage ...
 
9:16 PM
@JosephWright I was just looking,.. where is the name introduced? so how come that's read_image when seen from web
 
@DavidCarlisle writeimg.c
@DavidCarlisle I don't get it ... but it seems one can drop _
 
@JosephWright looking at tangle, but it's getting late
 
@DavidCarlisle Yup, don't worry about it
 
@JosephWright somewhere around here, I think
@ Single-character identifiers represent themselves, while longer ones
appear in |byte_mem|. All must be converted to uppercase,
with underlines removed. Extremely long identifiers must be chopped.
@ The original \PASCAL\ compiler was designed in the late 60s, when six-bit
character sets were common, so it did not make provision for lowercase
letters. Nowadays, of course, we need to deal with both capital and small
letters in a convenient way
7 bit ascii with both upper and lower case is so modern....
 
9:32 PM
@DavidCarlisle Did you forget a link to a question in your comment about the closed "Weakness of LaTeX" question?
 
@DavidCarlisle I think a lot of those files are unused ... only seem to need one
 
It's impressive how much space a small TeX file uses with tracing turned on.
