@Werner Ooh missed the palindrome by a hair or four.

@Werner Wow!

@UlrikeFischer, @LoopSpace, @TorbjørnT. [everyone else too!] I plan to get a bit more done on l3draw today then do a CTAN release for testing. It's going to be quite fluid at the moment in terms of interfaces and function coverage: I expect several releases in short order to address this.

@UlrikeFischer I'm also going to 'activate' the core colour support we've worked on, but it may not make it into the drawing graphics state today: probably in a future release

I use MacTeX. All I ever do with tlmgr is tlmgr update --all, yet from time to time it removes packages for no apparent reason, then keeps giving me skipping forcibly removed package warnings.

I know I can fix that with --reinstall-forcibly-removed, but why does it happen?

Why do packages get removed in the first place?

There's a question on this:

The answer says, "This can normally only happen by calling tlmgr remove --force.". Yet it keeps happening without ever using the remove command, and not only to me. Is it a bug?

@Szabolcs because their authors asked that they be removed, usually.

@Szabolcs It sometimes happens to me if the installation/update was not successfull because I had e.g. the docu open in some pdf reader.

@LoopSpace Personally I think ALL programmatic drawing environments should have the hobby algorithm for drawing smooth curves. I would seriously welcome it in the kernel.

@WillRobertson Like I said, pull request welcome :)

@WillRobertson I have a feeling that l3draw might attract quite a bit of attention ...

@JosephWright Just cherry-pick directly from here: github.com/wspr/splines-matlab

@JosephWright Oh wait... :)

@JosephWright But yes, no rush, and I'll keep it in the back of my mind for a raining day...

@samcarter Learning the weird expl3 syntax is useful...

tex.stackexchange.com/q/415791 -- the op edited the example (suggestions in comments were taken too literally) and now the comments and most of the answers make no sense. delete?

@barbarabeeton Both questions of the user are pretty vague

Why does this error?

@ChristianHupfer Would you help me on this?

@alhelal \lambda etc. out of math mode won't work. Just look at the compiler message.

@alhelal unrelated to the error but odon't do \it{d} \it is not defined by default an when it is defined, using it that way will make the entire document italic. you could use \textit{d} but that is supposed to be math so use $d$ and $d_{i} not \it{d}\textsubscript{i}

Thank you both.

The error is because you used \mu in text mode. It should be $\mu_i = \text{service rate}$

@alhelal I am no beamer expert...

@ChristianHupfer No problem to get thanks.

@DavidCarlisle $d_{i} not works.

@ChristianHupfer -- well, yes, i agree. but does that imply that the question should be deleted, or that further editing should be done to restore the sense? as it is now, it's not really useful.

@barbarabeeton I would rollback... deletion of a bad question with good answers is awful.

@alhelal then you did something wrong. all the \it{} and all the \textsubscript in your example code are wrong and should be replaced by math markup.

@alhelal but for questions with code it is better to ask a question on site rather than in chat

@alhelal -- $d_{i} needs another $ at the end.

@UlrikeFischer I am sure that I didn't have anything open at the time, but some other process may have locked those files without my knowledge. I'm on a Mac though, which tends to be much more tolerant of deleting/overwriting/moving files while in use than Windows. I'm a bit confused though, as @David's comment seems to suggest that this is normal and the messages can be ignored ...

@barbarabeeton well yes, there is that:-)

I will come back after some times.

@ChristianHupfer -- okay. if i get some time later, i'll try to do that. (it has at least 8 edits. some by others than the op, and the ones that removed the blank lines are about at 2 or 3. so it's not just a simple rollback.)

@barbarabeeton Oh, I did not check that. Seems to be tedious then...

@Szabolcs well I'm no expert on tlmgr internals, but all i can say is I get them occasionally and don't worry about it:-) (I think for instance I got one at the last hyperref update as Karl and I had merged one of the "additional" packages into the main hyperref base, and so that hyperef-doc-source package was removed as a side effect of updating hyperref.

@barbarabeeton I would just add a blank line as the first line of the align

@DavidCarlisle -- thanks. did that. it's still pretty weak, but i think things make better sense now.

@Szabolcs Well it is rather normal for me (I often forget to close something) ;-) Like David I don't worry about it.

also error.

@alhelal you need to start with some basic latex tutorials, \[ starts math mode so $d_{i}$ inside the equation needs to be d_i and as I said before remove all the \textsubscript.

@alhelal \mu \textsubscript{i} = service rate is exactly the same error you had before

@DavidCarlisle How can I change this?

@alhelal as I said before ^^^^

@DavidCarlisle I didn't know that I can write \mu inside $$

@alhelal you can only use \mu in math mode. You can not use it in text, as you have done.

@alhelal You must write inside $..$ (or in a math environment)-- it's a math-mode- only command

@alhelal: If you want to have the letter mu in text mode, you can try \textmu from the textgreek package -- but it will look different from the usual \mu output -- this depends on the font used, of course

is it correct now?

This must be a clear duplicate.... of some question (;-))

@alhelal no look at the output! you need as I said before \ textrm{service rate} (or better \text with amsmath package) otherwise it will be math italic with no spaces

@DavidCarlisle like $\mu_{i} = \text{service rate}$

@DavidCarlisle I have solved my problem.

@DavidCarlisle codegolf.stackexchange.com/questions/156154/…

hasn't been any cricket chatter around here for a while. gordon found this, which is worth watching: twitter.com/cricketworldcup/status/964809150407442432?s=09

What do people think, should “e.g.” and “i.e.” be typeset with a thin space after the first period?

@HaraldHanche-Olsen not usually

@DavidCarlisle That's what I though. I am cleaning up a paper in which the authors did it inconsistently, so I started doubting myself.

@JosephWright xii is so readable compared to codegolf jelly language

@DavidCarlisle Of course

@LoopSpace ooh

@LoopSpace ooh kittens

@PauloCereda It's your choice: either I write expl3ducks or expl3kittens.

@LoopSpace follow your heart, my friend. :)

@LoopSpace the ducks version would be more useful for menu cards.

@DavidCarlisle oi

@DavidCarlisle Wow, Jelly actually looks well designed (*caveat: I only looked at the documentation for 30 seconds). I wonder how the user (or users??) actually program in it. That codegolf challenge is way less interesting considering the strings aren't included in the solutions.

@WillRobertson Wait for my macro language. :)

@WillRobertson What is this jelly thing?

@HaraldHanche-Olsen look at any answer on codegolf (programming challenge for shortest program) programs in jelly often win, seems you can program just about anything in a dozen or so bytes:-)

@WillRobertson yes it seems a pretty poor question I've seen better ones on that site (I don't follow it normally but they pop up on the "hot network questions" links from time to time:-)

I've just gone from never having used Minted before, to now having written my own language definition for it. Feeling quite pleased with myself over that.

@LoopSpace arara 4.0 is to be officially released before TUG 2018. :)

@PauloCereda try that with s/arara 4.0/my thesis/

@DavidCarlisle I cam up with a massive MWE. And it still aligns perfectly. Only in my real document do I get the white space. However, I have a VMNWE for a completely different problem.

Does anybody know how to use \appendix in a beamer document with ignorenonframetext? None of my existing slides for the LaTeX workshops will compile.

@cfr if you want me to look at the original you could always send me (or point me at) a zip file doesn't have to fit the site limits:-)

@DavidCarlisle Thanks, I may do that if I don't get anywhere in a bit. It is driving me crazy. However, now have this hyperref/beamer problem and sticking with the remember picture, overlay stuff is suddenly less pressing.

@cfr I've inherited hyperref, so hopefully the problem is in beamer, then you can blame @JosephWright

@cfr There was a bug recently with appendix but imho it should work now again.

@DavidCarlisle oh

@cfr: Cwac!

@PauloCereda actually a more realistic edit might be s/TUG 2018/my thesis/

@UlrikeFischer The bug report samcarter linked is open. And I don't really understand the discussion at the end.

@PauloCereda Cwac <3.

@DavidCarlisle ooh

@cfr How are you? <3

github.com/josephwright/beamer/issues/464

@PauloCereda I'm good at s commands, perhaps I should try vim.

@cfr the reason doesn't matter much. Try the wotk around above.

@UlrikeFischer ^^ (I realise you've posted a workaround there, I think. But the discussion seems to say it will apply regardless of mode and eventually they decide it is not worth fixing?)

@UlrikeFischer That's really helpful - thanks. However, it seems to hard-code the format, so I end up with something other than I'd usually get with article. That is, I expect it to just give me something like 'A app', but I get 'Part 1', 'Appendix' and '1 Appendix'.

@DavidCarlisle ooh

@UlrikeFischer Never mind. The code you posted does change the format, but the version which is in the current .sty which samcarter pointed to doesn't. Sorry for the noise.

@JosephWright Do you have any plans to update Beamer on CTAN to fix the \appendix bug? It is just that I'm posting workshop code on GitHub and it won't currently compile the slides. The fixed .sty file @samcarter pointed me to works fine, but it would be easier if beginners didn't have to deal with that if they have just installed their system. It's a lot easier to say 'update using tlmgr or TeX Live Utility` than 'well you need to download this one .sty and put it here and delete later.

@JosephWright If it will be a while, I should probably incorporate patch code into my code on GitHub. But I don't consider this idea, obviously, so if you're likely to update the distributed version soon, I'll probably just cross my fingers.

@PauloCereda Bit stressed about the coming strike.

@cfr oh no
