In my opinion, the following post should not have been deleted and I have voted to undelete it, even though the author has also repeated it in a new answer, because the author is clearly quite upset about it. The answer is not at all clear and I did not see the author's point until I read a follow-up comment. I also don't know whether the motivation for the alternative code line is valid or not. But the author is offering a different answer from the others.

@ChristianHupfer @Werner @percusse ^^^

1:00 AM

@DavidCarlisle Uploaded to CTAN… that was an easy one :)

@cfr Added a comment. It is not different. I think OP is not aware of the fact that he is doing the same thing in my answer without testing properly. There is no visible difference here because the difference is faded away. But his/her answer is wrong.

And a duplicate to mine + adding a wrong modification.

3:32 AM

@PauloCereda YES!!!

3 hours later…

6:34 AM

@Johannes_B if you need a volunteer – I'll gladly go through one or the other template

7:24 AM

@WillRobertson thanks.

@kwy don't say "Urgent!" it's not how the site works. "do not work" is not information that allows anyone to help, what error message do you get.

Hi, we have two very similar questions in the website which I think they are duplicates of each other; should they be managed to be merged or one of them to be closed?

Q: How to collapse unused parameters in moderncv?

I am writing my CV using the moderncv package. I already have adjusted the CV to meet my needs. Therefore I amplified the maximum number of parameters possible in the \cventry command.

Q: How to collapse unused parameters in moderncv's \cventry-command?

I am writing my CV using the moderncv package. I want to adjust the CV to meet my needs. Therefore I amplified the maximum number of parameters possible in the \cventry command.

@EnthusiasticStudent Hmm, same user too so a merge does look sensible

Enthusiastic Student

@JosephWright Yes, merge is a good option...

@EnthusiasticStudent Done

Enthusiastic Student

@JosephWright perfect. thanks. :-)

@DavidCarlisle On the LuaTeX business: based on Elie's latest mail, add Lua support for a 'banner' and log/warning/error to the kernel or to the add-on package?

7:57 AM

@DavidCarlisle, memoir 3.7e without autoloading etex just send of to CTAN. Decided to ignore other feature requests for now.

@daleif :-)

8:20 AM

@daleif thanks, Alain Matthes has agreed to update tkz-* as well, and I mailed Florent Chervet about his packages yesterday as well. So things looking good!

@DavidCarlisle good

@JosephWright kernel I think for the banner/write stuff. whatsits I stil think probably do a tex allocator anyway, that spelling thing only uses them from lua but given the e@alloc definition we could add (package or kernel) a lua version that just incremented count 26x from lua?

@DavidCarlisle Yes, agree whatsits go in the kernel

@DavidCarlisle I'll do all of this today

@DavidCarlisle Also booking room at Trinity :-)

@JosephWright better order extra biscuits for @PauloCereda

@DavidCarlisle yaaay

8:48 AM

@StefanKottwitz You've got mail :)

@PauloCereda seconded :)

@DavidCarlisle Hopefully have also fixed issue with UK-TUG website: we can have post categories again :-)

@clemens @StefanKottwitz and I are in charge now, so we could make the change I guess :-)

@JosephWright :)

@JosephWright the UK-TUG website is now hosted on one of @StefanKottwitz's servers?

@JosephWright have you informed UKIP that tex.ac.uk is (presumably?) hosted in Germany?

@clemens No, UK-TUG website is in Manchester, tex.ac.uk is currently somewhere in Germany as @DavidCarlisle says

@DavidCarlisle Shh, don't tell JISC

@JosephWright too late, messages already logged by gchq

9:01 AM

@DavidCarlisle Jonathan Fine has taken an interest :-)

@JosephWright :(

@JosephWright we should get Bruno to implement md5 in pdftex tex and compare how long it takes to checksum UnicodeData.txt

@DavidCarlisle Yes, performance would be interesting

@DavidCarlisle I mailed him directly about some of this

@DavidCarlisle For a start, it (perhaps) needs to work with tokens not just files: I missed the file option in the use we currently have :-) (I do plan to fix that!)

@JosephWright how do you md5 checksum a token (string and utf8 encode then checksum the bytes?)

@DavidCarlisle Manual says

> This command expands to the md5 of ⟨general text⟩ in uppercase hexadecimal format (same as \pdfescapehex). The primitive was introduced in pdfTEX 1.30.0.

And following that back

> This command converts each character of ⟨general text⟩ into its hexadecimal representation. Each character of the argument becomes a pair of hexadecimal digits. The primitive was introduced in pdfTEX 1.30.0.

@JosephWright ah but character=byte in pdftex

9:08 AM

@DavidCarlisle Yes

@JosephWright so you'd have to utf8 (or 16 or 32) to get a byte sequence

@DavidCarlisle I've not looked at how this works in LuaTeX, I have to say

@DavidCarlisle As I said, I realise I missed the \pdfmdfivesum file option anyway, so I'll be altering that (really it's most useful for files)

@JosephWright my guess would be inconsistently

@DavidCarlisle It doesn't really need to work for us across engines in any case: the idea is that with the same processing set up you should be able to check that the files are the same

@DavidCarlisle Lets see what Bruno comes back with (or we hammer out at TUG2015)

@JosephWright but even for files you have a choice of normalising eol or not, the checksum of a UnicodeData.txt presumably depends on whether you copied it with dos or unix line ends doesn't it?

9:14 AM

@DavidCarlisle Current code like I say will ignore this:

  \begingroup
    \everyeof{\noexpand}%
    \catcode`\#=12 %
    \edef\mdfiveinfo{\input#4.txt\space}%
  \expandafter\endgroup
  \expandafter\def\expandafter\mdfiveinfo\expandafter{\mdfiveinfo}%

Checking the download, Firefox respects line endings of original (it is an FTP transfer), so they are Unix

@DavidCarlisle That I know of, TL doesn't alter line endings across platforms (always Unix) and neither do half-decent editors, so for the problem of 'are the files the same' it should work

MiKTeX I guess may be more tricky

9:29 AM

@DavidCarlisle Unix line-endings for texmf tree with both TL and MiKTeX on Windows so any checking really only needs to worry about users own files

@JosephWright yes but it doesn't include UnicodeData.txt so if a user gets that file from unicode.org to check the checksum in unicode-letters.def it will pass or fail depending on how they copied it.

@DavidCarlisle Like I said, testing in Firefox you get LF line ends on Windows as it's offered as an FTP transfer. The number of people likely to copy-paste the file into Notepad for testing is ~0. The idea of having checksums is that they will help people who have some experience.

@DavidCarlisle Karl was the one keen on that checksum: I'm seeing them as useful for tracking down issues in a small number of cases

@DavidCarlisle Line endings are tricky, but at present the checksum in unicode-letters.def won't care about them like I said :-)

@JosephWright ftp if you do it by hand will translate text files line ends or not depending on the mode

@DavidCarlisle Probably depending on the client too

@JosephWright anyhow on conference call so bye for now:-)

10:12 AM

@DavidCarlisle I just checked and it looks like I've already done this but haven't got round to uploading the new version.

@NicolaTalbot I'm sure we all know that feeling

@DavidCarlisle So it will be fixed whenever I do get around to uploading it :-)

@JosephWright :-)

@NicolaTalbot thanks (I thought you mentioned you'd done it before but you came up in @egreg's sweep of tl2015 yesterday:-)

@DavidCarlisle For some reason glossaries always seems to scream for attention whenever I find the time to do bug fixes and the other packages get left behind. I've been about to upload the new version of glossaries for the past week, but once I've finally got that out of the way I'll see if I can sort out datatool.

10:33 AM

@NicolaTalbot Nice to see you here! Some days ago I was looking at \storeordinal in fmtcount; the definition is

\newcommand*{\storeordinal}[2]{%
  \expandafter\protect\expandafter\storeordinalnum{#1}{%
    \expandafter\the\csname c@#2\endcsname}%
}

None of those \expandafter is useful: the first two do nothing, the third is redundant. I'm also not sure about \protect.

\newcommand*{\storeordinal}[2]{%
  \storeordinalnum{#1}{\the\csname c@#2\endcsname}%
}

@NicolaTalbot ^^^^ should be the good one.

@egreg or even \value{#2}

@DavidCarlisle Yes, that's right:

\newcommand*{\storeordinal}[2]{%
  \storeordinalnum{#1}{\the\value{#2}}%
}

@egreg Oh, weird. I don't remember why I did that.

@egreg Okay, thanks.

or was the intention of the original expandafter to store the value of the counter at that point? (in which case you need some back

@DavidCarlisle I wrote the code so long ago, I can't really remember much about it, but I do remember there was a problem with ensuring the value was written correctly to the .aux file to ensure cross-references worked correctly. (Although that wouldn't have been for the storage commands.)

10:42 AM

define long ago :-)

@egreg It might be best to raise the issue on github github.com/nlct/fmtcount or I'll forget. I need to finish off the new version of glossaries and sort out datatool first.

@DavidCarlisle :-) The original code for fmtcount was in datetime which I wrote in the late 1990s. I think if I had a time machine I'd go back and tell myself not to write it ;-)

@DavidCarlisle I was just on the phone to Robin Fairbairns: the topic of some code from ~1993 came up :-)

@NicolaTalbot Sounds like an excellent plan

@JosephWright The joy of hindsight :-)

@NicolaTalbot Done

@egreg Thanks.

11:08 AM

@JosephWright I need to update etex.sty again

@DavidCarlisle ?

@JosephWright doing \endinput after a \DeclareOption but before \ProcessOptions is bad (and in etex.sty that's almost the whole file:-) I need to move the option declaration after the error checks.

@DavidCarlisle Ah

@DavidCarlisle A long-shot, but do you know Jonathan Fine's GitHub user name?

@JosephWright google does: github.com/jonathanfine (I assume that's the one)

@DavidCarlisle OK, that's the one I guessed too

11:15 AM

@JosephWright his homepage link on github goes to a wordpress blog with mathtran links so must be same I think

@PauloCereda Shot one hour ago at my favorite petrol station, you can even see my car :D

@ChristianHupfer ooh das auto!

I only know that because of Volkswagen. :P

@PauloCereda Shameless advertising :-P I would never, never, never post a picture showing the blue ARAL duck ;-)

@ChristianHupfer Alles super!

Christian Hupfer

1:15 PM

@PauloCereda: The blue duck is actually promoting a car wash :D However, the promotion was not successful so far, looking at my car :D

@ChristianHupfer oh :)

@ChristianHupfer Das Dustyauto!

Christian Hupfer

@PauloCereda My car feels offended :-)

@ChristianHupfer Oh no! I am sorry!

For those interested in the Enlgish/UK-TUG FAQ: github.com/uktug/uk-tex-faq

Stefan Kottwitz

@JosephWright Thank you for setting it up!

@StefanKottwitz No problem

@StefanKottwitz Really Jonathan's idea: I just got on quickly so it would be using the UK-TUG account

Stefan Kottwitz

@JosephWright Yes, I noticed it's there already, together with course material

@StefanKottwitz Course material was why I set up a UK-TUG account in the first place

Help please:

Q: How to set figures and tables captions in APA style (without using APA6 class)

2:45 PM

@JosephWright is faq-devel@tex.ac.uk still the place to report issues, or use the github issue tracker ?

3:12 PM

@DavidCarlisle GitHub would seem best, but let me agree a position with @StefanKottwitz!

@DavidCarlisle Pull requests also welcome, I think

@JosephWright I zapped luatexregisternames from my github

@JosephWright I started to look at this but it seems to be your package you can work out where to add detokenize to make š safe in a \csname :-)

@DavidCarlisle Only mine so there is a TL-friendly license

@DavidCarlisle Anyway, @egreg has it in a comment

@DavidCarlisle Understood

@JosephWright yes that was my fallback position, didn't realise to start with that that argument was never printed.

3:30 PM

@StefanKottwitz As @DavidCarlisle mentions, probably with a GitHub account set up the best way to log requests for changes in the FAQ is using the issue tracker there, plus taking pull requests. Does that sound OK? We can then decide when to sync with the server (automating that at some stage, perhaps).

@JosephWright The solution is in the manual, but of course @DavidCarlisle won't try reading it.

@egreg does it have a manual?

@DavidCarlisle Strange, no?

as @egreg will know, the Ashes started today: England 224 for4

Stefan Kottwitz

3:56 PM

@JosephWright Sounds ok! If it's not harder than writing emails - users should have it easy to report bugs or suggest improvements, rather mail than web GUIs for trackers (don't know if github issues can be initiated by mail)

@StefanKottwitz OK, let's say they can do either :-)

@StefanKottwitz I'll alter the sources we have, and hopefully Robin will be able to supply the conversion Perl scripts soon

@DavidCarlisle Go Australia!

@StefanKottwitz I've sent a mail to the current e-mail address: let's see if you get it :-)

4:21 PM

@egreg incorrect response.

@DavidCarlisle Out of cheese error?

Stefan Kottwitz

4:39 PM

@JosephWright I don't have a mail server running with that IP (don't know if mx has been changed)

@JosephWright ok, tested (via mxtoolbox.com), that IP has been changed

@JosephWright I'll think about it

@StefanKottwitz Have been sitting almost six hours just today, to fix and improve one of vels templates.

Stefan Kottwitz

@Johannes_B OMG and there are more

@StefanKottwitz Wasn't the first time today. I sent him a complete patch, he reverted some of it and also introduced spaced by deleting my percent signs making the code fail. I was furious ;-)

5:02 PM

@Johannes_B Is this latextemplates.com?

@TorbjørnT. yes.

5:33 PM

@MartinScharrer: Hallo!

Martin Scharrer

@PauloCereda hi

Glück auf @Martin, i wonder if i have ever seen you in chat before.

Martin Scharrer

@Johannes_B I'm not that often here since I finished my PHD and starting working

@MartinScharrer I noticed that. :-)

@MartinScharrer Hi

5:53 PM

@MartinScharrer No procrastination? Bad workplace. ;-)

Martin Scharrer

@egreg Well, I'm keeping busy. At least I got another patent application last week

@MartinScharrer Wow!

Martin Scharrer

@egreg Nothing big

@egreg It's a machine that converts TeX code into coffee. :)

6:21 PM

@JosephWright was `\bit` removed from `siunitx`?
\documentclass{report}
\usepackage{siunitx}
\begin{document}
\si{\bit}
\end{document}

@repurposer You need to load the units

\documentclass{report}
\usepackage{siunitx}
\sisetup{binary-units = true}
\begin{document}
\si{\bit}
\end{document}

@JosephWright Thank you, I must need coffee, i was staring right at it in the manual

@DavidCarlisle I see you've beaten me to replying to Frank: much the same as I thought

@DavidCarlisle Perhaps Frank was thinking of the expl3 tests?

6:42 PM

@JosephWright possibly.

7:14 PM

@PauloCereda On the train I transform wine into TeX code.

@egreg Almost, but not quite

The Alchemist Discovering Phosphorus

The Alchemist Discovering Phosphorus is a painting by Joseph Wright of Derby originally completed in 1771 then reworked in 1795. The full title of the painting is “The Alchymist, in Search of the Philosopher's Stone, Discovers Phosphorus, and prays for the successful Conclusion of his operation, as was the custom of the Ancient Chymical Astrologers”. It has been suggested that "The Alchymist" refers to the discovery of phosphorus by the Hamburg alchemist Hennig Brandt in 1669. This story was often printed in popular chemical books in Wright's lifetime, and was widely known. == Description == The...

@JosephWright a painting by Joseph Wright WHAT?!

:)

@PauloCereda Indeed: search for Joseph Wright, find my namesake of Derby

@PauloCereda nationalgallery.org.uk/paintings/…

@PauloCereda Not Joseph Wright, but I do like chemheritage.org/discover/collections/collection-items/fine-art/…

@JosephWright chemister nascitur non fit :)

7:21 PM

@PauloCereda So there's somebody older than me here!

@egreg ooh

7:34 PM

@TorbjørnT. What do you think about the site and templates in general?

@PauloCereda, @StefanKottwitz Do you want me to add you to the FAQ GitHub with commit access?

@JosephWright Up to you. :)

@PauloCereda It does seem I am in charge now

@JosephWright ooh the boss. :)

@PauloCereda Hmm, interesting: for a repo owned by an organisation I can't add individuals, only teams

7:43 PM

@JosephWright You probably have to add individuals to organizations, maybe.

@PauloCereda Yes, what I mean is you can't mix the two

@PauloCereda I'll probably create a new team for the FAQ: I've created one for our committee and the training material so it's easier to manage

@JosephWright Ah cool.

@JosephWright: Can you name it The UK FAQ Taskforce Duck Corporation of World Domination?

Please please please please please please pleeeeeeeeeeeeeeease.

@PauloCereda You are added, now what's @StefanKottwitz's GitHub user name?

@Johannes_B Haven't really looked much at the site to be honest. I guess templates can be an easy way to get a quick start with a document, but on the other hand they can promote "mindless" use of preamble matter, as people will just use/reuse whatever is in them without considering if it is actually necessary. But then, that's more of problem with people than templates.

This is like the rush hour on the UK-TUG website!

7:49 PM

@JosephWright github.com/Stefan-Kottwitz

@TorbjørnT. Unfortunately, your last sentence is very true. :-/ Thanks for you input :-)

@PauloCereda Ah, rather easy

@JosephWright Where am I added? :P

Is it possible to create a non escapable kind of loop with \afterassignment? Like that anytime you do an assignment, something is automatically done and automatically re\affterassigned?

In “other words” can one “clean” whatever someone has \afterassigned before?

@PauloCereda You should have an invite

7:54 PM

@JosephWright ooh

@PauloCereda Try github.com/uktug

@Manuel @Manuel \def\foo{\foo}\afterassignment\foo would make the next assignment interesting

@DavidCarlisle Eek

@JosephWright he did ask:-)

@JosephWright Got it. :)

7:56 PM

@DavidCarlisle But that's just a basic infinite loop.

The answer is easy, if you know what exactly has been afterassigned you can redefine the appropiate commands.

@Manuel yes but I could insert any amount of afterassignments \writes \defs etc inside \foo to obfuscate it but any loop in a macro language will be that basically

@DavidCarlisle I misexplained. I meant something like \def\foo{\afterassignment\foo}\afterassignment\foo.

@Manuel but that doesn't loop:-) perhaps you want \def\foo{\afterassignment\foo\count0=1}\afterassignment\foo

uk.tug.org/2015/07/08/english-tex-faq-sources-on-github

@DavidCarlisle No, I didn't want to loop. I mean that that would endlessly put \foo after every assignment.

And my question is (was) how do I get out of tha crazyness?

8:01 PM

@Manuel "Is it possible to create a non escapable kind of loop " --> "No, I didn't want to loop" :-)

@DavidCarlisle "Is it possible to create a non escapable kind of loop" --> "I misexplained." :-)

Also I said “kind of loop”, what is that infinite \foo that appear after any assignment? That's kind of a loop?

@Manuel i expect a group will always save you.

with \def\foo{\afterassignment\foo}\foo then {\count0=1}

@DavidCarlisle Why? I mean, the only way I thought of shutting down that was \def\foo{} or, if it's more complicated than that \let\tmp\afterassignment\let\afterassignment\@gobble\let\afterassignment\tmp.

@DavidCarlisle Mmm.. I'm not that expert :) The \afterassignment is always global? If it happens in a group, what would happen out of it?

Stefan Kottwitz

@JosephWright joined

@StefanKottwitz Great stuff

8:10 PM

@Manuel the token still gets inserted but may be undefined, so as you say if you know the token name \let\foo\empty stops things as \foo gets inserted after that but is empty

Stefan Kottwitz

@egreg I do the same on flights, they usually got a fine selection

@Manuel why did you ask? (you could insert this in one of @Johannes_B's templates:-)

Stefan Kottwitz

@JosephWright I'll fix mail tomorrow, there's still a relay issue because of different mx host and domain name, to be fixed

@StefanKottwitz Probably the first thing to do is adjust the README and github.com/uktug/uk-tex-faq/blob/master/markup-syntax so it's clear how to edit

Stefan Kottwitz

@JosephWright Installing Postfix on the web server brought me reminders: some forgotten blogs now send me mails about comments to be moderated - one has 130.000 comments in the mod queue

@JosephWright To be clear, the blogs were tests filled with a bit stuff. And spammers found them and generated comments.

8:14 PM

@StefanKottwitz :-)

@StefanKottwitz So mail to tex.ac.uk will get to you?

Stefan Kottwitz

@JosephWright Yes, it does. I just have to setup a mail server for this. Did not have on the web server.

@JosephWright I made a postfix forwarder, but this had the relay issue

@JosephWright I'm sure to fix it tomorrow as I'll see the Linux gurus at work :-)

@StefanKottwitz Feel free to forward all of the tex.ac.uk mail to me

Stefan Kottwitz

@JosephWright happily :-D

@StefanKottwitz Great

Christian Hupfer

8:28 PM

@JosephWright: Sorry, I flagged it possibly while you were converting it to a comment -- it did not reload automatically

@ChristianHupfer No probs

@StefanKottwitz I can choose between just two.

9:04 PM

@PauloCereda oooh ;)

@clemens Exactly. Do it. :)

@PauloCereda Done :)

@clemens :)

9:23 PM

@clemens Package acro: You are supporting addchap, but not addchap* and as far as i have seen, there is no mark mechanism built in. Opinions?

Enthusiastic Student

Hi... I just have a primarily opinion based question! :))) Have you prepared your CV yourself or used a prepared CV package like modernCV? Which one do you prefer? I had prepared my CV myself in an article document class but I see that the existing template look really nice but have limited capabilities...

@EnthusiasticStudent I've gone with a roll-it-yourself approach: in the end CV classes tend to be a bit awkward

@EnthusiasticStudent texdev.net/?s=curriculum+vitae

Enthusiastic Student

@JosephWright good link... thanks. I also think that your approach is the best.

@JosephWright your own CV on your website is great. I personally type each of my papers in the LaTeX file. Do you do so, or just import a .bib file into your CV? I think that working with bib files is a more correct way.

9:42 PM

@Johannes_B open problem: I want to change that option in such a way that the user can use any code as long as it needs a mandatory argument. I really should put that on my TODO list so I don't keep forgetting it

@clemens :-)
