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

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" ? -- luigi

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

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

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

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 . -- luigi

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: http://archive.contextgarden.net/message/20080404.200709.454e4740.en.html ;)

This is what I mean . -- luigi
