[Bug] Links don't work if you put an array in them.

mykael

$exit[0].text is a valid variable name.

<<$exit[o].text>> will print out it's value.

[[<<#exit[0].text>>|somewhere]] however does not work.  The editor and runtime both seem to the the closing square bracket on the array reference as the end delimiter for the link.

Should I raise an issue for it?

Try:

[[$exit[0].text|somewhere]]

mykael

The editor rejects it (fails to parse it and highlight it as a link) as soon as I put the close square bracket on the array reference in.

Printing is, I think, necessary to get the variables contents shown on the screen - it seems to work for simple variables.

There are a couple of cases where a link is valid even though the syntax highlighter says otherwise, especially if using SugarCube.

Did you test what "The Pixie" suggested by generating a HTML file and testing it, or did just type it into the editor and notice the highlighter was not happy?

mykael

Tried it in Test and [[$exits[0]|Self]] as the link produced $exits[0]|Self]] as normal text.

[[<<$exit[0]>>|Self]] produced  North|Self]] - as normal text.

[[<<print $exits[0]>>|Self]] also produced North|Self]] - as normal text.

Last test code was:

<<set $exits to [ 'North', 'South']>>
[[<<print $exits[0]>>|Self]]

I believe that issues with $variables that include property accessors (or at least those containing the bracket notation) in the vanilla headers are probably a known quantity (I could be wrong though).  Regardless, it can't hurt to raise an issue about it, so I would probably suggest doing so.

Tangentially, since SugarCube was brought up, in most places where SugarCube supports $variables, it supports variables of arbitrary complexity.  Meaning:


/% This will work fine as-is. %/
[[$exit[0].text|somewhere]]

/% So will this monstrosity. %/
[[$l.m.n.o.p['q']["r"]['s'].t.u.v.w.x[$y].z|somewhere]]


The only caveat is within the wikitext link and image markup.  If the $variable ends in the square-bracket notation and would adjoin the closing square-brackets of the link/image markup, then you'll need to add space between the $variable and the closing square-brackets of the markup (since it would otherwise be ambiguous to the parser).  For example:


/% This won't work, since $link["location"] directly adjoins the closing square-brackets of the markup. %/
[[$link["text"]|$link["location"]]]

/% This is okay. %/
[[$link["text"]|$link["location"] ]]

/% This is also okay (though now I'm just being silly). %/
[[
$link["text"]
|
$link["location"]
]]
