Hi,
How do you make a custom TOC entry that links to the correct page?
In the following example, the last TOC item is not hyperlinked, and
all the section hyperlinks are incorrect (off by one). Note that the
chapters and sections are separate pages.
\setupinteraction[state=start,]
\setuphead[chapter,section][page=yes,continue=no,]
\define[3]\SectionTOC{#3 #2}
% Using alternative causes the cross-reference to be off-by-one.
\setuplist[section][
alternative=interactive,
command=\SectionTOC,
]
\starttext
\placecontent
\startchapter[title=Chapter]
\dorecurse{4}{
\startsection[title=Section]
Level \recurselevel.
\stopsection
}
\stopchapter
\stoptext

You’re wrong, there are links for all section entries but the area for the hyperlinks
are shifted upwards by half a line, it’s easier to notice when you increase the space
between the entries.
\setupinteraction[state=start]
\setuphead[section][page=yes,continue=no]
\define[3]\SectionTOC{\ruledhbox{#3 #2}}
\setuplist
[section]
[alternative=interactive,
command=\SectionTOC,
before={\blank[2*line]}]
\starttext
\placecontent
\chapter[title=Chapter]
\dorecurse{4}
{\section{Section}
Level \recurselevel.}
\stoptext
This problem can be fixed by adding \noindent in front of the \hbox command in the defintion
of the interactive alternative, i.e.
\startsetups[\??listrenderings:interactive]
\edef\p_command{\listalternativeparameter\c!command}%
\ifx\p_command\empty
[\currentlist: \currentlistentrynumber\space -- \currentlistentrytitle\space -- \currentlistentrypagenumber]%
\else
\listparameter\c!before
- \hbox \strc_lists_get_reference_attribute\v!all \strc_lists_get_destination_attribute {
+ \noindent\hbox \strc_lists_get_reference_attribute\v!all \strc_lists_get_destination_attribute {
\p_command\currentlistentrynumber\currentlistentrytitle\currentlistentrypagenumber
}
\listparameter\c!after
\fi
\stopsetups
but to ensure all entries all placed below each other you have to set "before=\endgraf“ with \setuplist.
BTW: The "vertical“ list alternative has the same problem with the wrong area for the hyperlink.

Thank you, Wolfgang.
This fixes the issue. I worry, though, that these types of solutions
are a bit brittle. If the interactive alternative definition changes,
then the TOC code could break.
If the definition in strc-lst.mkvi were to change to something like:
% Perform a half-line adjustment in some cases
\listparameter\c!indent\hbox \strc_lists_get_reference_attribute\v!all
\strc_lists_get_destination_attribute {
Then the usage would look like:
\setuplist[section,][
alternative=interactive,
indent=\noindent,
before=\endgraf,
]
That would leave a clue for maintenance purposes, making the overall
code less brittle.
Thoughts?

as soon as you need to mess at that level it's easier to just write a
proper specific setup than to configure 20 something things for a 10
line setup ...
