That's an s-expression, I like s-expressions. So much
so that I have just put together this parser:

it is capable of being given the input in chunks, so
doesn't have any limitations on size. as it reads
through the expression, it builds up a list of every
form inside it, e.g.
["gtk_func" "gtk_text_buffer_insert" "buffer" "iter"
"Hello world" "-1"]
and when it gets to the end, it currently just prints
them out, but you know what to do with them.

anything in " quotes can take literal characters
(other than '"' and '\') and it also expands the
\" -> "
\n -> newline
\r -> return
\\ -> \
\t -> tab

does that cover everything needed for client -> server
messages? apart from the escaping, all the languages
should be fine with that format, and it still looks
natural (to a lisp programmer).

please forgive the shoddy code, i'm a bit rusty when
it comes to C, but it compiles and the tests run, so
what could possibly go wrong :)

good night,

from the not so cold UK.
