@IceBoy I think this is a button in StackExchange high-mods' desk. They click to some button and it is enabled. Your mods can contact them in the mod chat room I think.

Great :D

I'll let them know, thanks

we don't have mods yet

@IceBoy Also please write down somewhere on that question that MathJax != LaTeX :)

what does != mean?

=/=

@IceBoy Ah yes. not equal to :)

ok

thanks again :-)

@IceBoy good luck

@percusse btw, has anyone ever told you that your avatar looks like a young Boltzmann?

@IceBoy It's from a similar era. Lyapunov

unfortunately shared similar sad stories too

@percusse Casa Bonita tacos. :(

Good maen...

@ChristianHupfer 'lo.

@PauloCereda: Hello, duck master ;-)

Making use of an otherwise useless ornament .....

Spent the entire day to make Spyder work with python3. No result.

Another sunday....

@percusse oh no :(

@tohecz The OP influenced you: it's easier having all textual numbers oldstyle and lining in math; the problem, perhaps, is knowing how to do it. ;-)

@egreg yeah. Well, I thought that redefining arabic should be fine, but obviously not quite :)

@tohecz Now you know.

@tohecz That's a last resort!

@egreg I prefer to ask any font tweaking questions on the site, since I'm not really a font TeXnician :)

@percusse :(

@PauloCereda Do you know anything about PyQt4 or 5

@percusse A little.

I have 5 and it fails installing by saying I should have 4.6 or newer.

I think it only checks 4. 6 >5. 3

@percusse Maybe the runtime is linking the older Qt runtime.

@PauloCereda I don't have any old Qt.

@percusse Oh.

I also tried with PyQt4 that fails for some klingon reason

@egreg our edits overlapped:-)

@DavidCarlisle Your macro expander wasn't working properly.

@egreg did you like my drop caps answer?

@DavidCarlisle I see; it's impossible it works, as it's written with vim

@DavidCarlisle I'll downvote it ASAP.

@egreg you should be honoured

@DavidCarlisle Of being squashed? Or of being treated like an ornament?

@egreg both?

Good night chat.

A small question

\parindent, \hsize, etc. are dimensions? Or are “primitives”?

@Manuel boith

That is, if we do \let\tmpa\hsize can we later do \tmpa=3cm?

Or does TeX look for the explicit \hsize. In that case, what happens if we do \let\hsize\relax?

@Manuel yes but \tmpa then is not just a dimen register it is the hsize primitive and setting tempa will affect linebreaking

@DavidCarlisle Okey, so all those parameter dimensions of TeX are not just dimens but primitives.

@Manuel \let\hsize\relax is fine (best to have saved it under a different name first;-) that's how latex3 code renames all the primitives

try \let\tmp\hsize \show\tmpa and tex will show you that the definition of \tmla is teh primitive \hsize

I meant, they are primeives that behave like dimens but are primitives.

@DavidCarlisle Okey. Thanks for the fast question solving.

@Manuel well depends what you mean by "all" the ones that are, are, the ones that aren't aren't. \textwidth for example isn't a primitive it is a dimen register

@Manuel well the primitive dimens may be assigned using a <dimen> syntax like a dimen register but unlike a register they then have side effects, setting \hsize controls line breaking, setting \parindent affects indentation etc

@DavidCarlisle Yeah, okey, I meant those that are. Same happens with some kind of \everypar (I'm not sure that is one of them) that behave like toks but in the end they are primitives.

@Manuel yes but that's a good example \everypar in latex is not a primitive it is a token register the original primitive everypar is hidden and accessable as \frozen@everypar

@DavidCarlisle Everthing is solved then :) Thanks.

@Manuel good night:-)
