hash for buffer contents
Dear list, I have the following sample: \ctxlua{require("util-sha")} \starttext \startbuffer[abc] samples \stopbuffer \cldcontext{utilities.sha2.hash512("buffer-name")} \stoptext Is there any way to get "utilities.sha2.hash512" with the contents of the "abc" buffer? Many thanks for your help, Pablo
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": \startbuffer[test] One Two Three \stopbuffer[test] \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. -- Max

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
