Dear list, I need to add checksums to files I attach to PDF documents.
Following the suggestion from https://stackoverflow.com/a/326715, I wrote: \starttext \startluacode function document.capture(cmd, raw) local f = assert(io.popen(cmd, 'r')) local s = assert(f:read('*a')) f:close() if raw then return s end s = string.gsub(s, '^%s+', '') s = string.gsub(s, '%s+$', '') s = string.gsub(s, '[\n\r]+', ' ') return s end function document.sha256(file) command_output= document.capture("sha256sum -b " .. file) context(command_output:sub(0,64)) end function document.sha512(file) command_output= document.capture("sha512sum -b " .. file) context(command_output:sub(0,128)) end \stopluacode \def\shatwo#1% {\ctxlua{document.sha256("#1")}} \def\shafive#1% {\ctxlua{document.sha512("#1")}} \shatwo{Desktop/i-context.pdf} \shafive{i-context.pdf} \stoptext Directories are a problem here. I mean, \shatwo{Desktop/i-context.pdf} cannot work in Windows. Which would be the way to make it work in Windows?
