Hello,
I would like to activate a remapper in a style or module file. How could
this be done?
I tried this without success:
\defineremapper[filterItem]
\remapcharacter[filterItem][`•]{\item}
\appendtoks \startfilterItem \to \everystarttext
\prependtoks \stopfilterItem \to \everystoptext
TIA for any hints!
Cheers, Peter

Why so complicated!
\catcode`•=\active
\def•{\item}
and of course use ConTeXt’s own commands for the above code.

kep in mind that the remapper is just a hack and will not be extended
etc etc; i'm not going to handle interferences with other mechanisms

I think the point is this :
in some situations one find useful to convert things like • in macros like
\item .
Of course, it can be done with preprocessing , or with some ad-hoc macros
in lua code , etc
So, apart \remapcharacter, are there any other safe ways to "remap
character" ?

one solution mentioned was making that character active and then do an
unexpanded def which makes it roundtrip safe; of course we should leave
characters like : untouched
the remapper works on all input and it might result in unwanted side
effects .. imagine that someone defines symbol 1 as • and gets \item
instead

Wolfgang mentioned the method with active character.
And there is also this one:
\startluacode
function my_replace(line)
return line:gsub('• ', '\\item ')
end
callback.register('process_input_buffer', my_replace)
\stopluacode
\starttext
\startitemize
• bla
• bla
• bla
\stopitemize
\stoptext
I like the latter one, because it permits also replacing whole words and
much more. But you need to be careful, see also:

there was an article many years ago something like "Active characters -- No
thank you"

this is true -- it's not a general solution it's a trick , it if you abuse
then....

Maybe I'm not able to express what I mean .
