Dear list, it seems as if there are braces missing in the definition of \buff_save around #2.
\def\buff_save[#1][#2]% {... {\setupcurrentsavebuffer[\c!list={#1},\c!file=#2]}% ...} I think they are missing, because it makes the following work, even though arguments and key-value arguments shouldn't be mixed up. \startbuffer[hash] foo \stopbuffer \savebuffer[hash][hello.txt,prefix=no] \starttext \stoptext I think you should either make a third argument for a key-value list or just make the second argument the key-value list. Then users could input \savebuffer[hash][file=hello.txt,prefix=no].
