Re: [NTG-context] Accessing raw titles in textcommand in TOC
Yup, this works gloriously for reversing titles. And more complex
transformations (in my case mostly weird stuff like generating morse code for
titles to be shown in TOC) can be done by specifying "list" for all chapters as
Hans suggested. Thank you!

Re: [NTG-context] Accessing raw titles in textcommand in TOC
The "list" seems capable of handling even complex lua macros. It does not
require much work to add this to all chapters manually in my case so this
solution works for me (and there's always awk and such for larger things).
Thank you!

There is no user level command to access the raw list title which is needed in
your case but there is another way to achieve the desired result.
When you change the text direction for the list text (you can't use the align
key because this would change the positions of the chapter and page numbers)
the complete title is printed in reverse order.
begin example
%\setuplist[chapter][textcommand=\reversehbox]
\setuplist[chapter][textcommand={\unframed[location=low,align=righttoleft]}]
\starttext
\completecontent
\chapter{Sample Chapter}
\stoptext
end example

Hello,
I would like to display titles differently in TOC than they appear in
text. For example, MyChapter1 -> 1retpahCyM. Basically any highly
non-trivial transformation that really needs Lua.
\starttext
\completecontent
\startchapter[title={Sample Chapter},list={retpahC elpmaS}]
\stopchapter
\stoptext
I've written simple Lua macros before, but the following approach trying
to define textcommand does not work since I can't find the way to pass
the raw title to my transform function.
\startluacode
userdata = userdata or {}
function userdata.mytransform(title)
--context(title) --this is just fine, but isn't very useful
context(string.reverse(title))
end
\stopluacode
\def\transformtitle#1%
{\ctxlua{userdata.mytransform([==[#1]==])}}
\setuplist[chapter][textcommand=\transformtitle]
\starttext
\completecontent
\startchapter[title={Sample Chapter}]
\stopchapter
\stoptext
When I print the actual title that is passed to mytransform, all I get
is \currentlistentrytitle and I haven't succeed expanding it (and
there's all kind of formatting stuff and so on going on I suppose).
Sections have "deeptextcommand" which is somewhat what I'm after here,
but I've not found similar option for TOC. So, is there a way to get
just the raw titles?
