Dear List, currently, I have to compose technical documents with a lot of source code in it. There're readers demands for a way to copy&paste this source code directly from those documents into their terminals. I tried ConTeXt’s attachment functionality, it is … ok. But most people don’t like files attatched to PDFs. Moreover, they must open it in an editor before getting contents in terminals. So,
normally a viewer is quite restricted out of security reasons
is there any possibility in ConTeXt/Lua a document reader can click on a source code statement and the content of an external file (the plain code, without any typesetting) will be loaded into the clipboard, so that they can paste this plain source code into their terminal programs to use it directly?
here is an option (the last examples need an upcoming beta as i added better space support for verbatim comments)
\setupinteraction[state=start]
\starttext
\startbuffer[a]
for i=1,10 do
print(i)
end
\stopbuffer
\typebuffer[a]
currently: \comment{\cldcontext{buffers.getcontent("a")}}
\blank
hacked: \comment{\cldcontext{string.gsub(buffers.getcontent("a"),
"\string\r","\string\n")}}
\blank
new, space honored, still hack:
\comment[space=yes]{\cldcontext{string.gsub(buffers.getcontent("a"),
"\string\r","\string\n")}}
\blank
new, buffer honored: \comment[buffer=a]{}
\blank
idem: \comment[space=yes,buffer=a]{}
\stoptext
\definefallbackfamily[mainface][serif][texgyrepagella]
\definefontfamily[mainface][sans][texgyrepagella]
\setupbodyfont[mainface]
\starttext
