Ack. Figuring out how to translate an arc from SVG to l3draw is going to mean that I actually have to do some Maths. Bleugh.
(Found an SVG that doesn't use arcs ...)

@AlanMunn running marmots?

@marmot Well marmots can run. But maybe not at the moment.

5 hours later…
7:53 AM
@LoopSpace Oh no!

8:32 AM
@LoopSpace Joseph has done some support for spline approximations of arcs, not enough?

8:53 AM
@LoopSpace Docs not clear?

9:08 AM
@JosephWright I don't know if you changed something in the meantime but when I made the duck I had to guess which argument is the target and which the control points.

@UlrikeFischer I'll tighten up
% \begin{function}{\draw_path_curveto:nnn}
%   \begin{syntax}
%     \cs{draw_path_curveto:nnn} \Arg{control1} \Arg{control2} \Arg{end}
%   \end{syntax}
%   Joins the current path to the \meta{end} with a curved line defined by
%   cubic Bézier points \meta{control1} and \meta{control2}. The bounding box
%   of the path (and image) will fully-contain the curve and control points,
%   \emph{i.e.}~it may be bigger than strictly necessary to contain the curve
%   \emph{alone}.
%   \begin{demo}
%     \draw_begin:

@JosephWright sounds good (and I confused arc and curveto).

@UlrikeFischer Ah, cool

10:33 AM
@egreg, @yo' On TUG2018, I was just saying to @PauloCereda that a talk about the importance of semantic mark-up would be good. Either of you interested?
Or perhaps @DavidCarlisle with his XML hat on
(But he's not going :()
I have a feeling I'll need to do a new l3draw release soon!

@UlrikeFischer My problem with TeX Live is still present, do you think I should reinstall everything?

@CarLaTeX Huh?

@JosephWright Good call!

My Windows 10 system has just started acting like and usual Windows system: every now and then, it suddenly stops by itself. Unfortunately, it happened while I was updating TeX Live (2017). Now, if I try to start the TeX Live GUI, I get immediately the error: Problem with installation: cannot ...

@JosephWright I just got asked again (getting to be an annual event) to talk the week later at balisage.net but I'm probably going there either.

10:36 AM
@DavidCarlisle Indeed

@DavidCarlisle they better have an opening and closing ceremony, considering they are about markup. :)

Oh boy, I am a nerd duck.

@DavidCarlisle Sounds fun
I see l3kernel made it into TL today

@PauloCereda no these are serious markup people and can use SGML implied tags to close (and open) automatically

@JosephWright hm so it's safe to update

@PauloCereda Yes

10:37 AM
@DavidCarlisle HE IS A WITCH
@JosephWright: YAY NOTHING BROKE

@CarLaTeX I suspect you can't get help here, if you want to avoid re-installing you could try asking on texlive list Norbert and/or Akira who understand tlmgr and windows builds may be able to debug.

@DavidCarlisle OK I'll try, thank you!

@JosephWright do you use warwick ctan mirror for tlmgr? it seems to be acting strangely recently mostly saying there are no updates, I had to switch to oxford to get latest batch

@DavidCarlisle Oxford

@JosephWright Currently my default is warwick which has been fine until a few weeks ago but I think I'll switch as I have to use the --repository flag to force oxford more often than not recently

10:47 AM
@DavidCarlisle :(

10:57 AM
@DavidCarlisle I use Oxford too

@DavidCarlisle Yes.
@DavidCarlisle: I don't trust our mirrors.

@JosephWright I'm willing to take it I think, but it could mean I'd probably deliver two talks.

@PauloCereda you do know you live in Brazil don't you?

@JosephWright There's documentation?!? What kind of crazy programmer are you?

11:02 AM
@DavidCarlisle /quacks in despair
@LoopSpace HE IS A WITCH

@JosephWright Slightly more seriously ... I suspect that what gets fed into the final drawing commands from \draw_path_arc:nnnn is closer to what SVG specifies than if I work out the radii and angles. So I might dig down into that sometime soon, but for the moment I'll do the math as I'm lazy.
@AlanMunn I hereby invoke "l'esprit d'escalier":
The first rule of TikZ club is that you don't talk about xfig ... and pstriks
I mean, the first rule of TikZ club is that you don't talk about xfig or pstricks ... or picture mode
That is, the first rule of TikZ club is that you don't talk about xfig, pstricks, picture mode ... or xymatrix

@LoopSpace the documentation for the pgf version of that command is somewhat sketchy and consists of referencing the svg spec, so it ought to be doing something close to what you need:-)

Shall I come in again?

@LoopSpace MS Paint it is then

@DavidCarlisle Exactly. But I'll need to sit down with a piece of paper and stare at the code for a bit to figure it all out.

11:07 AM
@LoopSpace Our two weapons are fear and surprise... and ruthless efficiency
And toast. Lots of them.
Unless you are a pie bloke.

perfect arc, no math required

@DavidCarlisle A very steady hand, I must say. :)

@DavidCarlisle good :)
@DavidCarlisle David Carlisle, the new Giotto!

I found an answer! With the \newcounter command you can save a variable temporarily. So the code below saves the page nubmer temporarily and than sets the pagenumber back when the arabic pagenumbering is reinstated. :) \newcommand{\createpart}[2] { \newcounter{tempPageNumber} \setcounter{...

11:22 AM
@CarLaTeX Italians get a lot of practice at drawing o

11:38 AM
@DavidCarlisle LOL

@DavidCarlisle wow

@PauloCereda you could set up the inaugural freehand blackboard duck drawing championship at tug2018

@DavidCarlisle ooh

12:16 PM
@DavidCarlisle damn. looks like I no longer can read the texlive list through gmane, no new messages since the 17. The xetex list is down too.
@PauloCereda ^^^prehistoric ducks?

@UlrikeFischer o.O

@UlrikeFischer too modern for me, I just subscribe to the lists:-)

1:11 PM
@DavidCarlisle I like it very much (and doing for ages now) as I can read a lots of lists in the newsreader without getting tons of mails.

1:25 PM
@PauloCereda that's a sketch of @DavidCarlisle's head ;-)

@ChristianHupfer ooh

So l3kernel etc. are now updated

1:58 PM
@PauloCereda: I found that it is possible to keep a certain number of revisions or even all with tlmgr

@ChristianHupfer cool!

@PauloCereda: See the screen shot (German version), having Auto backup → change the number to either more than 1 or to -1, meaning all revisions will be kept
@PauloCereda: I have not found the command line version of this setting, up to now...
@PauloCereda: Ah found it: tlmgr option autobackup 5 (for example)

@ChristianHupfer How nice!
@ChristianHupfer Great, thank you!

@JosephWright I never spell bezier with an accent:-)

@DavidCarlisle ᵬẽ̎žĩ̎e̋r̯

2:13 PM
@JosephWright , @egreg, @yo' -- if any of you take up this challenge, i offer to read and comment. (i have some suggestions that i prefer not to mention here.)

@barbarabeeton include me in this plan, please. :)

@PauloCereda -- i thought your talk is about arara, not semantic markup.

2:29 PM
@barbarabeeton he needs multiple talks to avoid working on his thesis

@DavidCarlisle Or deflect the attention of us all from his \phantomthesis ...

@barbarabeeton I can talk about more things. :)

@PauloCereda as I just said

@barbarabeeton I have peer pressure to talk about arara! I was even threatened to rewrite my abstract!

@PauloCereda -- like a thesis? (see ... even i am guilty of this.)

2:31 PM
@DavidCarlisle ooh prediction
@barbarabeeton oh no
/quacks in despair

@PauloCereda: Paulo, I have some suggestion for you: \expandafter\procrastination\finishthesis ;-)

@ChristianHupfer ooh can I have \relax somewhere? :)

@PauloCereda \let\relax\relax ;-)

ooh

2:48 PM
@ChristianHupfer this would mean secretly finishing the thesis ahead of time, then visibly procrastinating acting as if it was before the thesis was finished. Surely no one would be so dishonest as to do that?

@DavidCarlisle Of course not. I don't want to deprive you of being mean to @PauloCereda ;-)

2 hours later…
5:05 PM
@snoobdogg: You have an answer now so its not really relevant but in future I'd recommend if being asked for dimensions to give them in more standard units of measure. Centimetres or inches would have worked. Mice are a less commonly used unit and thus many people would have to look up the conversion of "common mouse" to units they are familiar with. I certainly am left still having no actual idea of how big this thing is. :) — Chris 2 days ago

@JosephWright New unit to be added to siunitx? :)

5:31 PM
@AlanMunn :)

5:45 PM
@JosephWright I'm guessing that l3svg would not be a good choice of file name, and \draw_svg:n implies that it is "official". While I'm still in the mucking about stage, are there better name conventions?

@LoopSpace ltx3<something> if you want to release a non-official expl3 package purely at the code level
@LoopSpace Name-wise, I don't see a problem with \draw_svg:n, thought you might want to use your own prefix (drawsvg?): everything here is pretty experimental anyway

@PauloCereda Just listened to Corazón by Maluma feat. Nego do Borel. Is it common to mix languages in a song?

@Johannes_B Que Sera, Sera

6:02 PM

@marmot that's a lot more weird than
@Johannes_B famous english song with real authentic foreign words (the english are known for mastery of languages) ^^^^

@DavidCarlisle The authors of the song are Jay Livingston and Ray Evans, both American. The former from Pennsylvania, the latter from New York State.

@egreg @DavidCarlisle And the green tick goes to...

@AlanMunn Hitchcock?

@egreg No, you, The Man Who Knew Too Much. :)

6:16 PM
@egreg I was including the colonies

@DavidCarlisle You lost Pennsylvania and New York a few years ago, didn't you know?

@egreg So some say

6:34 PM
@AlanMunn Wikipedia helps

6:59 PM
@marmot I know such a behaviour from me as well when I am confronted with opera ... I am whistling too then. And with whistling I mean screaming ;-)

7:30 PM
@ChristianHupfer It's just surprising that the fake marmot gets so much attention. ;-)

@marmot What, that's a fake? ;-)

@ChristianHupfer Of course. The lady is certainly not a marmot. I guess she never even hibernated.

@ChristianHupfer But this is the problem, she is just faking the very beautiful songs we marmots can sing. No wonder that you don't like operas. ;-)

7:49 PM
@marmot Yes, it's almost like the voices of the sirens that 'enchanted' Ulysses ;-)

8:02 PM
@ChristianHupfer Just wondering if you like real marmot music better.

@marmot Much better... I like the Beatles Marmottles from Liverpool :D

I need to manipulate subsets of data within a for loop in R. I can create it like this: for(i in 1:n) { assign(paste("df_",i,sep=""),subset(df_raw, id==i)) } But then, how can I access to df_i , to add a column or to do anything else to it? Thanks

@ChristianHupfer agree

@ChristianHupfer just coming back from 4 hours opera ;-)

9:29 PM
@barbarabeeton @JosephWright @PauloCereda @egreg as I think about it, I start to realize that I won't be able to grab this challenge; I'm not able to devote much time to stuff like this.

@yo' -- too bad, you'd have some very good ideas on the subject. (but lack of time understood.)

@PauloCereda abnt I assume? tex.stackexchange.com/q/417073/2693

9:45 PM
@UlrikeFischer Oh my....

@ChristianHupfer It wasn't so bad ;-). And it had its amusing moment: Someone sang "mein lieber Schwan" in earnest.

@UlrikeFischer Sorry, opera is not meant for me...

10:04 PM
@ChristianHupfer Does \phantom{Opera} solve your issues?

@ChristianHupfer It isn't my favorite in the theater either -- I had to go as part of the job of my husband -- but it really was quite interesting and not every one was dead at the end.

@marmot That or \let\opera\relax ...
