Hi Pablo,
Is there any way to get "utilities.sha2.hash512" with the contents of the "abc" buffer?
You can use "buffers.getcontent" or "buffers.raw":
Many thanks for your reply, Max. This is exactly what I needed.
\starttext \startluacode require("util-sha")
local content = buffers.getcontent("test") -- local content = buffers.raw("test") -- same result local sha512 = utilities.sha2.hash512(content) context(sha512) \stopluacode \stoptext
Depending on what you're trying to do, the "filter" module may be helpful here.
I think the following function is just fine for me: \startbuffer[test] just a test \stopbuffer \starttext \startluacode require("util-sha") function document.sha512buffer(buffer) return utilities.sha2.hash512(buffers.raw(buffer)) end \stopluacode \def\shabuffer#1 {\cldcontext{document.sha512buffer("#1")}} \shabuffer{test} \stoptext Many thanks for your help again, Pablo
