Hi, list! My question is just like that: how do I pass buffers or \input
content to \processtokens. What I have done so far:
\tolerant\protected\def\foo#={\ifparameter#1\or\oof{#1}\fi}
\protected\def\oof#1{<#1>}
\startbuffer[ofo]
% Output: Th<i>s <is> not a <question> anymore!
Th{i{s {is} not a {question} anymore!
\stopbuffer
\starttext
\processtokens\foo\foo\relax\space{Th{i}s {is} not a {question} anymore!}
% Neither \inlinebuffer nor \rawbuffer work in the example above
\stoptext
I didn't try to decipher this (you probably need expansion someplace),
I've also tried a variant of the mechanism described in OPmac trick
described here <https://petr.olsak.net/opmac-tricks-e.html#etoks> to
process content token by token, but it only works with \normalinput. Any
suggestions or guidance? Thank you in advance.

s = string.gsub(s,".",{ ["{"] = "<", ["}"] = ">",})
context(s)
end
}
