@marmot Hi are you around?

marmot

@AlanMunn Yes. (I guess the tree costed you some amount of energy... but the winter nights are long and cold in Michigan, right? ;-)

Alan Munn

@marmot A bit ;-), and I realize there's a problem with my code that I don't quite understand.

marmot

@AlanMunn Maybe you should ask the author ... just kidding ... if it's expl3 I have no clue.... if it is TikZ, maybe;-)

Alan Munn

@marmot if you run my code and replace \istcntmx(0-1)(1-2) with \istcntmx(0-1)(1-2)+15mm..25mm+ for example, it should change the size of the triangle, but it doesn't, and I'm really not sure why, since I didn't change anything substantial in the code I don't think.

@marmot well I think it's a TikZ issue, but it could be the interface between the two.

marmot

@AlanMunn Give me a few minutes. (Will just make my last answer a tiny more streamlined and then look at it.)

@AlanMunn If I replace \draw [#5] (#3) -- (#3-1) -- (#3-2); by \draw [#5,red] (#3) -- (#3-1) -- (#3-2); only two edges become red. And I do not understand which variables get assigned 15mm or 15mm. If I do \typeout{\cntmdefault@levdist} I always get 8mm.

Alan Munn

@marmot One of the branches is drawn with the child command.

@marmot What's weird is if you replace \istcntmx(0-1)(1-2)+15mm..25mm+ with \istcntm (the original command) it changes the distance correctly.

marmot

@AlanMunn I see. Thanks! And where do the 8mm come from (and what are the names of the variables that get assigned 15mm or 25mm)? (And why do you use \tikzstyle?

Alan Munn

@marmot I just copied the code from the package and the author uses tikzstyle.

@marmot From what I understand, #7 and #8 are assigned the values, and become \cntmlevdist and \cntmsibdist in the command.

marmot

5:02 AM

Yes, but `\tikzstyle` may be part of the problem or maybe not. I tried:
\NewDocumentCommand\istCntmRootx{t'O{south}r()D(){0,0}O{dashed}G{.5}D+.{\cntmdefault@levdist}D.+{\cntmdefault@sibdist}}
{
\IfBooleanTF {#1}
{
\cntmdistance{#7}{#8}
\tikzstyle{level 1}=[level distance=\cntmlevdist,sibling distance=\cntmsibdist]
\setistNullNodeStyle[black]{\istdefault@nullnodesize}[black]
\node (#3) at (#4) [null~node] {} [\xtgrowprime=#2] child[#5] child[#5];
\draw [#5] (#3) -- (#3-1) -- (#3-2) -- (#3);
\setistNullNodeStyle{\istdefault@nullnodesize}

Alan Munn

@marmot Changing it to tikzset doesn't do anything

marmot

@AlanMunn True. But I still do not understand where the 8mm come from.

Alan Munn

@marmot That's the value of \cntmdefault@levdist but that should be overridden.

marmot

I also did
\NewDocumentCommand \istcntmx
{ t' O{\istdefault@grow} r() D(){0,0} O{dashed} G{} D+.{\cntmdefault@levdist}D.+{\cntmdefault@sibdist} }
{ \typeout{\cntmdefault@levdist}
\IfBooleanTF {#1}
{
\istCntmRootx' [ #2 ] ( #3 ) ( #4 ) [ #5 ] + #7 .. #8 +
}
{
\istCntmRootx [ #2 ] ( #3 ) ( #4 ) [ #5 ] + #7 .. #8 +
}
}
but it again gives me 8mm, which seem to be the default value. Meaning that the default does not seem to get overridden

@AlanMunn Wait, my bad.

@AlanMunn Spaces! \tikzset{level~1/.style={level~distance=\cntmlevdist,sibling~distance=\cntmsibd‌ist}}

Alan Munn

@marmot Damn. That's the problem (again).

marmot

5:13 AM

@AlanMunn Yes. Before effectively you had \tikzstyle{level1}=[leveldistance=\cntmlevdist,siblingdistance=\cntmsibd‌ist] so TikZ just defined a new style level1 which it never used.

Alan Munn

@marmot Right. Thanks. It's weird that in the package itself the spaces don't seem to matter, but withing ExplSyntaxOn it does.

marmot

So it also could not stumble over errors saying that leveldistance is not a valid key.

Alan Munn

@marmot Right. As soon as I changed the level 1 to level~1 it started to throw errors. But until then they just don't arise.

marmot

@AlanMunn I guess @egreg knew before you asked the question that the issue is caused by spaces. ;-)

@AlanMunn tikz and expl3 can be fun - I constantly add and remove ~ in keys ;-).

marmot

5:18 AM

@AlanMunn Oh, you're saying @UlrikeFischer removed the ~'s and it's not your fault. ;-)

Alan Munn

@marmot When @UlrikeFischer reads this I'll be fast asleep and unable to defend myself. :)

@marmot Thanks for your help. Off to bed now.

marmot

@AlanMunn I actually saw your conversation that's why I tried this. (OK, I tried to use \pgfkeysvalueof to see what's going on and saw that spaces were missing and then I recalled that I saw something on the chat....) (I guess you might want to use \tikzset but it is not really important, it's just that if you use it others will copy it and use it in places where it matters.) Good night!

Alan Munn

@marmot Yes I replaced the tikzstyle stuff.

Is this tex.stackexchange.com/questions/468490/… still true?

@PauloCereda Could you please renew your answer here: tex.stackexchange.com/questions/420094/…? Thank you!

Paulo Cereda

@CarLaTeX in which sense?

CarLaTeX

@PauloCereda Ah no, you already did it in September, I didn't notice that, I'll try and let you know, sorry!

Paulo Cereda

@CarLaTeX we ducks are good at updating questions. :)

CarLaTeX

@PauloCereda Of course!

Could somebody please tell the BBC Sport Cricket page that India are now playing their 4th Test against Australia, and that continuing to display the 3rd Test scorecard is a fair indication that they're not fully awake As usual...

@CarLaTeX well one could probably write a 10-page article about the various way how to interpret the claim and in which view it is true and in which not.

@UlrikeFischer Oooh

Paulo Cereda

@CarLaTeX ooh
