TeX, LaTeX and Friends

@cfr The VLE? Yes, but I never upload TeX-related files

cfr

05:55

@JosephWright the very same. it doesn't provide any details beyond ris, bib or (translated to english) references but the former means pdf, I think. but it insists my .bib has no data.

this bit of it is new. and it might be some kind of plugin for reading lists - it is hard to tell.

Joseph Wright

@cfr Can you send me a screenshot? I can try something out if I know what exactly you are doing

Arg, people exploiting. abug in v2 I fixed in v3 :)

cfr

@JosephWright I can ... but I'm no sure what you want a screen shot of. Here's the error:

Joseph Wright

@cfr I meant where are you uploading :)

cfr

@JosephWright it looks exactly the same?

Joseph Wright

@cfr Hmm, I'm not at all sure where you are uploading - so I'm a bit stuck

cfr

The only thing in between is the system file selection dialogue. this is why I said I could send a screenshot, but I think it would help.

Joseph Wright

@cfr ^^ The standard upload page I'm used to - which looks nothing like what you are seeing :)

@cfr I assume you are using BlackBoard 'classic' no the new Ultra version? We've switched this year, but I can still get at the older interface (which is what I've shown above)

cfr

@JosephWright no we're using ultra. we switched last year.

@JosephWright do you have anything which looks like this ^^?

but in english, probably ...

Joseph Wright

@cfr I'm looking :)

cfr

@JosephWright it is not the standard file upload. this is specific to reading lists. and it wasn't like this last year.

Joseph Wright

@cfr Ah, reading lists - we use another product for those (Tallis), that links to BlackBoard

cfr

@JosephWright I think it would help -> I didn't think it would help ...

@JosephWright yes, I'm not sure this is blackboard. we were using leganto. I am not sure if this is a new version or something else.

if I knew what it was, i might be able to search, but it is just labelled "Reading Lists" everywhere (even in welsh).

and the help link takes me to cu's learning & teaching academy, which doesn't even have an option to search?!

it wasn't great before, but you could get to blackboard's site and you could search cu's own resources.

@JosephWright sorry. I thought i said that, but I just checked and I didn't.

Joseph Wright

@cfr :)

@cfr I'm pretty sure this is an add-in - I can't find anything 'native' in Ultra

@cfr At UEA I'd ask our library contact and/or teaching technology people (we have a dedicated group to support Bb, etc.)

@JosephWright I feel that way every time I see an afterpage question

cfr

@JosephWright I spent a good many hours last year trying to get help from IT and I still can't access eduroam on my laptop. I can't even get them to restore power which we've not had since before the summer. but the library is generally better. (IT are centralised and just ignore tickets.)

@JosephWright I'm also pretty sure it is an add-in.

Anyone else getting a lot of emails from CTAN? I normally only get a daily summary, but not I get a heck load of emails.

daleif

Is there a reason why the low level coffin stuff described in interface3, does not have a \coffin_ht_plus_dp:N similar to the one boxes has, \box_ht_plus_dp:N, at least just to be consistent with the box tools.

Joseph Wright

@daleif probably my fault :)

daleif

09:05

@JosephWright It might also be nice with a \coffin_typeset:Nnn same as \coffin_typeset:Nnnnn but the last two args are 0pt. At least in my uses I rarely need to offset. I just use it as if I was using \parbox.

daleif

09:37

Regarding replacing \parbox and minipage with coffins. What is the equivalent of this \begin{minipage}[t][13.7mm][t]{\linewidth} in coffin terms? As far as I can see there is no tools to set a coffin of a specific height.

Ulrike Fischer

@daleif if you are writing something that at some time will need tagging support then minipage and coffins are not equivalent, as the first is tagging aware but the second not. There you would have to add the support manually.

daleif

11:49

@UlrikeFischer these are for letters and letter like, so not sure if taggeing will be relevant.

Joseph Wright

12:26

@daleif Added for next release

Ulrike Fischer

@daleif letter like documents are imho quite important. Think only at bank account reports (I already get tagged versions here), invoices, confirmations for reservations, invitations. Most PDF-documents that I get per mail currently are of this type, and lots of them are sent to a larger audience. And once I find some time I will certainly try to tag my own invoices.

Skillmon

@yannisl If you want to you can send me your custom PGF handlers and I'll take a look at them (not to add them to l3keys, which I can't, but to take a look at them, help you define l3keys-based alternatives via non-handlers, and finally to consider them as pseudo feature requests to expkv-def). If you don't know how to reach out to me: One of my mail addresses can be found in expkv-bundle.pdf.

daleif

12:46

@UlrikeFischer I don't think I've even seen a tagged PDF in the wild (though haven't looked for them either).

yannisl

@Skillmon @Skillmon thanks, I will prepare something and send it to you.

Skillmon

13:07

@yannisl But don't expect me to be fast, my week is quite full. Maybe I'll manage today's late evening, but no promises.

daleif

Given that I don't use xelatex, at all, are there any specific pitfalls one need to be careful with? My converted class works just fine with pdflatex and lualatex, but xelatex gives a Missing } inserted with no apparent cause.

Joseph Wright

@daleif Without context, 'no'

Skillmon

@daleif XeLaTeX has some quirks, but that sounds rather odd.

daleif

13:23

Xelatex is just too annoying to work with, considering to just drop support for it. For the fonts I'm using we have a special encoding for it to work with pdflatex, for xelatex and lualatex we use fontspec. But apparently xelatex still reads pdftex.map and try to make sense of it and fails as it is a custom encoding for one of the files. So I get xdvipdfmx:warning: Creating ToUnicode CMap failed for ..., xdvipdfmx:warning: Invalid map record in fontmap line 4805 from pdftex.map

yannisl

@Skillmon Thanks I will send them some time next week, and send you a message here when I do and take your time

daleif

As I guessed font related. Sign.

mickep

@daleif Yes, best option is not to use fonts.

Skillmon

@daleif changing fonts is easy, as long as the font is named Computer Modern and looks like this: <image of Computer Modern glyph table>

daleif

@mickep Here it is the custom encoded one, it has four chars, and we already had to do nasty tricks to get xelatex to access it it in the first palce.

mickep

13:29

@daleif Is the font different from other fonts?

daleif

@mickep Quite, the chars live in the private area. But we have had it working. Need to check the archives.

Will debug.

mickep

@daleif Good luck!

daleif

13:57

That was an interesting one. Say we have the following
\ifxetex
\NewDocumentCommand\AULogo{}{{\tracinglostchars=-1\AULogofont\XeTeXglyph\XeTeXglyphindex "uniF030" }}
\NewDocumentCommand\AUSeal{}{{\tracinglostchars=-1\AULogofont\XeTeXglyph\XeTeXglyphindex "uniF031" }}
\NewDocumentCommand\AUBSSLogo{}{{\tracinglostchars=-1\AULogofont\XeTeXglyph\XeTeXglyphindex "uniF032" }}
\NewDocumentCommand\AUBSSLogoInverted{}{{\tracinglostchars=-1\AULogofont\XeTeXglyph\XeTeXglyphindex "uniF033" }}
\fi
Running under Expl3.

When, in a clean document under xelatex I use \AULogo and then \AUSeal, then xelatex complain about simple group levels that haven't been closed. If I enclose the whole thing in \ExplSyntaxOff ... \ExplSyntaxOn, then there it no warning, and the original missing } goes away.

So it is the missing spaces that \XeTeXglyphindex needs that are missing.

And the space after " is important. That was an annoying one

Probably haven't tested this package under xelatex after I converted it into Expl3

Joseph Wright

@daleif Oh, that - yup :)

daleif

14:43

@JosephWright not an easy error msg to deciffer

Joseph Wright

15:00

@daleif I'd make a thin wrapper to avoid the issue

cfr

@UlrikeFischer so coffins should be avoided?

David Carlisle

@cfr they are good for zombies

Ulrike Fischer

15:23

@cfr no, but if you want to write tagging aware code you need to understand the difference and perhaps add tagging code directly.

cfr

@DavidCarlisle you mean the non-philosophy kind?

@UlrikeFischer hmm. thanks. I'll try to remember that. (I'm not yet trying.)

David Carlisle

@UlrikeFischer I'm sure my answer was quicker and more helpful
