@JosephWright @DavidCarlisle Can you take a look, some files of babel in the subversion repository are severely broken, e.g. english.dtx, Texts at line ends are cut off.

David Carlisle

@HeikoOberdiek hmm will look

@HeikoOberdiek try now

phew tl2014 installed at last

Heiko Oberdiek

3:37 AM

@DavidCarlisle I see you have reverted to a previous version. The cause? Something for @JosephWright to prevent that he getting bored?

David Carlisle

7:20 AM

@HeikoOberdiek yes there was an edit across the whole repository to remove white space from ends of lines (following a comment from you I think) but in that one directory it acted in a bizarre way, so I reverted the checkin for babel only in all other directories it seemed fine.

@WillRobertson Hi, would you please take a look on this topic tex.stackexchange.com/a/175572 ? I read the manual of verse and there is nothing written on the numbering over multiple stanzas. In the only example (on page 13) the numbering on the last line is missing. Or is this best practise for verse numbering? Don't know. Maybe you can clarify that a bit. Thank you very much for your work.

@WillRobertson Hope, you don't mind asking you this way here. Couldn't find an issue tracker or alike.

Paulo Cereda

10:23 AM

@egreg: I borrowed 90% of your code, hope you don't mind. :)

egreg

@PauloCereda For what?

Paulo Cereda

@egreg Here: tex.stackexchange.com/a/175589/3094 :) I borrowed the number examples. :)

egreg

@PauloCereda Oh, nice!

Paulo Cereda

@egreg I'm terrible with numbers. :P

Joseph is now our Lua expert, right? :)

Finally, something good coming from Brazil. :P

Heiko Oberdiek

@DavidCarlisle Yes it was my suggestion )and I have seen the removal of white space in another directory. I wanted to see, if there are some last-minute changes. (There were, e.g. ltnews21.tex, thus I made a new release of latex-tds. Happily babel is no longer part of latex-tds.)

Q: Time passed from a specific date

I would like to put in my resume N years experience in Java where N would be generated based on the date provided in the LaTeX file. Preferably in rounded years, i.e. If the beginning date was 2012-06-04 and the output was generated on 2014-04-04, then the N would be 2.

datetime

Guys, is this possible?

I can provide an hybrid solution.

That is, with no TeX at all. :P

LaRiFaRi

@JosephWright Sorry for asking here. Could you link me to a post on this side or the page in your manual, explaining the different spacing in this MWE: `\documentclass{article}
\usepackage[locale=DE]{siunitx}
\begin{document}
$0,7 = \num{0,7}$
\end{document}`

should I always use \num for any decimal in my formulae?

Joseph Wright

@PauloCereda I wish

@HeikoOberdiek @DavidCarlisle Hopefully have now got the hang of this business: stray spaces should be stripped from all of the L3 stuff (at least all of the .dtx files)

@LaRiFaRi If you want the 'auto-formatting'

@LaRiFaRi Note that as it stands your spacing will be wrong in the simple 0,7 case

@LaRiFaRi \num is relatively slow: I'm hoping to improve it but it needs some time!

LaRiFaRi

but why is the spacing wrong for the simple case? Every "normal" user (strange to call people, not knowing siunitx, normal...) would just type 0,7 in an equation

are the always set wrong? Why is the so?

@JosephWright can't find 'auto-formatting' in your documentation. Which approach would you recommend? Of course, correct spacing (and as a plus, the grouping) would be nice without using \num in every formula

Q: German language: use of comma in numbers

In German the comma rather than the period is used as a decimal separator and the dot is used as a thousands separator: 12.345,67. The comma creates some unwanted space when used as in $12.345,67$. Is there a light-weight package or some macro to support this? (I'm not looking for automatic forma...

math-mode formatting

@LaRiFaRi icomma is a much 'lighter' solution if you don't need to be able to quickly reformat for non-German use

LaRiFaRi

@JosephWright and an other topic, as you seem to like xparse (or write it?): Couldn't solve this issue with normal macros or with xparse tex.stackexchange.com/q/175577 But not my problem. Just in case you wanna try.

Joseph Wright

10:54 AM

@LaRiFaRi @DavidCarlisle and Frank Mittelbach wrote it (I think): I just do fixing things!

LaRiFaRi

@JosephWright Thanks for the link. Thats interesting. Strange, I never noticed that before. Thanks for your time.

Q: A quick way to determine whether a number is prime by hand

I need a quick way to determine whether a number is prime by hand. Any suggestions?

prime-numbers

Paulo Cereda

@egreg He could try a sieve of Eratosthenes using his hands. The method works for primes < 10. :P

egreg

11:10 AM

@zscoder If you participate to a math contest, you should know immediately that $4\,294\,967\,297$ is not prime. — egreg 18 secs ago

Paulo Cereda

@egreg LOL

Joseph Wright

12:17 PM

@DavidCarlisle Really getting the hang of this 'sweep over the whole repo' thing :-) Nex step: install GOW for my Parallels Windows installation on my Mac to avoid line-ending disasters!

David Carlisle

@JosephWright so that means you have a unix-based oprating sustem running windows in a virtual machine over that and then install a set of unix-emulating tools in the virtual machine? makes sense to me:-)

6

Joseph Wright

@DavidCarlisle Yup

@DavidCarlisle Make life easier for testing stuff

David Carlisle

@JosephWright sure it sounds almost logical:-) meanwhile I've just been "upgraded" to an office365 mail server so if I you send me mail it'll probably be stuck in Seattle somewhere.

Joseph Wright

@DavidCarlisle :-)

@DavidCarlisle Mainly for the LaTeX2e stuff that I need the Gnu tools on my Windows VM: the build scripts are now Win-only, so I have to checkout the files using SVN on Windows and that means CRLF line-ends. For L3 work, I can get away with most things!

David Carlisle

12:37 PM

@JosephWright we could set the eol property in svn so unix line endings were used whatever platform.

@JosephWright which is why I have to do a balancing act to get it to work under cygwin. for latex2e-public not so bad as there are only 4 or 5 bat files, but for l3 there are dozens of the things, and I don't have a working setup yet....

Joseph Wright

@DavidCarlisle That did occur to me :-)

@DavidCarlisle Don't the Makefiles work with Cygwin?

David Carlisle

@JosephWright oh the l3 ones? I don't know, the 2e ones assume cons works which is an optimistic assumption

Joseph Wright

@DavidCarlisle L3 assume something Unix-like, but hopefully not too much beyond that (we had some bash-only stuff I'd picked up by copy-pasting, but that got removed)

David Carlisle

@JosephWright tl2014 update this morning seemed to give me an expl3 updated but not latex yet.

@JosephWright I'll try typing make somewhere see what happens

Joseph Wright

@DavidCarlisle Anyway, I'm going to do some revisions on them to try to bring more into line with the L2e ones Frank wrote plus to have more similar behaviour on Windows and Unix

@DavidCarlisle Cool

@DavidCarlisle Start with something simple :-) (l3kernel make unpack, perhaps)

David Carlisle

12:42 PM

:15362717 $ make unpack
echo "Unpacking files"
Unpacking files
cd /tmp/l3test/test/l3kernel ; \
for I in l3.ins l3doc.dtx ; do \
  tex $I > /dev/null ; \
done

@JosephWright so trying top level make check: what could go wrong:-)

Joseph Wright

@DavidCarlisle :-)

@DavidCarlisle Like I say, I'm planning to do some revisions of all of these, hopefully this week: let me know if there is anything I need to consider for Cygwin

David Carlisle

@JosephWright although longer term it would probably be good to just have one set of build scripts rather than you having to maintain make and bat in parallel

Joseph Wright

@DavidCarlisle Suggestions on how to achieve this?

@DavidCarlisle The only obvious approach is to write everything in Lua and use texlua

I guess I could look at that

David Carlisle

@JosephWright I was wondering if there is a simple enough implementation of a bat interpreted for linux or mac (ie without invoking all of wine) but basically the bat files only need some tests and some loops, it ought to be able to run them in linux...

Joseph Wright

@DavidCarlisle The aim was to avoid requiring more stuff than absolutely required (otherwise I guess writing Makefiles that work on Windows would be an option): like I say, Lua is perhaps the best plan as it allows a move to 'just needs a modern TeX system', which we assume anyway.

I know the TeX Live scripts have all gone that way

David Carlisle

12:50 PM

@JosephWright yes lua sounds sensible but since we assume perl anyway it would be more fun to do some perl to convert and execute the bat files on the fly ie automating this tldp.org/LDP/abs/html/dosbatch.html

Joseph Wright

@DavidCarlisle I was thinking if things were written in Lua then there wouldn't be any Perl requirement :-)

David Carlisle

1:01 PM

@JosephWright that does seem to be the sensible route

@JosephWright speaking of lua do you understand the luabase packaging stuff? I removed it all in my inputenc trials to avoid having half of contrib as a dependency, but I may have removed too much and if you load fontenc later it gives me a wrap over the knuckles for not using luatexbase interface and using the primitive calbacks directly.

Joseph Wright

@DavidCarlisle One for @HeikoOberdiek, I think!

David Carlisle

@JosephWright yes well it was mostly his stuff I was avoiding:-)

@JosephWright meanwhile make check passes except for two:

Joseph Wright

@DavidCarlisle A quick look at Lua suggests sorting out some form of make scripts should be doable

@DavidCarlisle One each from xfss and template?

David Carlisle

$ find /tmp/l3test -name \*.diff
/tmp/l3test/test/l3packages/xtemplate/xtemplate004.diff
/tmp/l3test/test/l3trial/xfont/l3xfss001.diff

Joseph Wright

@DavidCarlisle Yes: the standard ones

David Carlisle

1:11 PM

@JosephWright so all good then damn now I've no excuses:)

Heiko Oberdiek

@JosephWright lualatexbase is not me, try Élie Roux et. al.

Joseph Wright

@HeikoOberdiek Ah

David Carlisle

@HeikoOberdiek It was clear enough what it's doing, but if we were to make inputenc work better on luatex out of the box it would be good to pull in some lua without the following. It's easy to do that but then you don't get the benefit I assume the package loader gives of loading multiple cooperative packages, so some middle way I think, but luainputenc currently does:

lualatex \\RequirePackage{luainputenc} \\stop

produces

(...tex/lualatex/luainputenc/luainputenc.sty
(...tex/generic/oberdiek/ifluatex.sty)
(...tex/generic/ifxetex/ifxetex.sty)
(...tex/luatex/luatexbase/luatexbase.sty
(...tex/generic/oberdiek/luatex.sty
(...tex/generic/oberdiek/infwarerr.sty)
(...tex/latex/etex-pkg/etex.sty)
(...tex/generic/oberdiek/luatex-loader.sty
(...scripts/oberdiek/oberdiek.luatex.lua)))
(...tex/luatex/luatexbase/luatexbase-compat.sty)
(...tex/luatex/luatexbase/luatexbase-modutils.sty

which is fine for a contributed package but not for the core I think.

Paulo Cereda

@egreg Our beloved Patrick. :)

topskip

@PauloCereda I really like the Del Piero picture.

Paulo Cereda

@topskip me too! :) I missed some ducks though. :)

egreg

@topskip But not with LuaTeX! The original has LaTeX!

David Carlisle

@HeikoOberdiek yes will once I have my head round the issues, although it's not really the details of that package as with the luatexbase stuff

@PauloCereda is there something I should be reading?

Paulo Cereda

1:45 PM

@DavidCarlisle Patrick's keynote. :)

@DavidCarlisle xii.tex makes a cameo.

topskip

@PauloCereda No! David should not read the slides. I make fun of TeX using xii as an example.

@egreg ..which was an obvious mistake. It's the LuaTeX team who is sponsoring Del Piero

Joseph Wright

2:00 PM

@topskip So how would you see this in relation to going beyond LaTeX2e: are we wasting our time entirely? Should we instead be defining some input format to be translated to Lua (much as Jonathan Fine would like but with s/Python/Lua/g)?

topskip

@JosephWright No, I don't think so. There is a huge area for "classic LaTeX documents" (say homeworks, books, and more advanced things). I believe that should stay the same, while admitting it's not always the perfect way to go

Joseph Wright

@topskip And xparse :-(

@topskip Phew :-)

topskip

@JosephWright Sorry about that, but acutally nobody in the room was able to tell what exactly was going on

Joseph Wright

@topskip Well you did pick quite a complicated internal part

topskip

@JosephWright that was my intention, of course (I wanted to make a point and the more complicated the code looks, the better my point is)

Paulo Cereda

2:08 PM

@topskip oopsie. :)

Joseph Wright

@topskip Of course: I'd have gone for something from Bruno :-) (l3regex or l3fp)

topskip

@JosephWright yes, I was a bit in a hurry doing the slides, of course I had them prepared right at the conference during the (polish) talks

@JosephWright My customers would never want to touch (La)TeX code, that's why I hide it completly. But this also means, it's limited to the functionality that I provide, and I know many people who would not accept that limits.

Joseph Wright

@topskip Makes sense

I have finally put some examples online: speedata.github.io/publisher/manual/examples-en/index.html

Hi, anyone knows, how I refresh my font-cache for LuaLaTeX?

I deinstalled a font but still can use it

Windows XP, MikTeX

Stephan Lehmke

@topskip The cow came much later.

LaRiFaRi

Apostolos Syropoulos sent me a new version of the Asana Math font but now, I can't test it, because LuaLaTeX is still using some old stuff. Don't know, where that come from. I guess, Luaodfloat (is that written correct...) has built its database and I need to refresh this.

@AdamLiter: just a minute, I found out I need R. :)

Adam Liter

@PauloCereda no worries! Sorry for not clarifying that in the question. :-)

Paulo Cereda

@AdamLiter Nah don't worry. :)

Hmm, I shortened it down to this but it still seems more verbose than necessary

path quarter, q[], otimes;
quarter = (0,0) -- (.5,0) & quartercircle & (0,.5) -- (0,0);
for i=1 upto 4: q[i] = quarter rotated (45+90*i); endfor
otimes = q[1] & q[2] & q[3] & q[4] -- cycle;

Q: Raper vs. Rapist; Why the shift in suffix?

I've always been vaguely aware of 'raper' as an alternative to 'rapist', as a vaguely wrong sounding, possibly archaic formulation - nowadays, it's most often heard from speakers of English as a second language, for whom the construction is slightly irregular compared to other similar verbs. But...

etymology

egreg

@hftf It connects two paths, provided the first ends where the second one starts.

@egreg you should write short snappy answers that don't take months to read,

egreg

@DavidCarlisle That one is pretty short. Possibly the OP needed so much time because of \pdfpkresolution=8000

David Carlisle

@egreg as is customary, I didn't actually look at your answer:-)

egreg

@percusse “Rapist” always recalls this quotation from the TeXbook: But computers are notoriously bad at hyphenation. When the typesetting of newspapers began to be fully automated, jokes about “the-rapists who pre-ached on wee-knights“ soon began to circulate.

@egreg Hahaha. Spot on

By the way I didn't know that ELL is also that notorious in terms of competition.

oh this one is ELU

i meant ELU ... meh

when two reviewers rant about a paper (one of them is yours truly), this always happens; a third reviewer pops up and writes stuff like this :

This paper is well organized. The presentation of this paper is clear. The related research methods are clearly presented and explained. The mathematic derivations and proofs are rigorous. Previous work in this paper has been reviewed and the references are adequate. This is a solid and publishable manuscript.

Eternal spanking seems the only option here.

anyone got any idea what this code is trying to do? tex.stackexchange.com/questions/175729/…

@percusse Sounds copy-pasted

@PauloCereda I've got to run. I'll probably be back in a little bit, but thanks again for the help so far!

egreg

@DavidCarlisle xii.tex is clearer.

David Carlisle

@egreg that is the gold standard in clear, well laid out TeX code.
