C-c C-c recompiles the top-level form at point and installs it in a running
program at that program's next frame boundary. Verified against sand: an
unsaved buffer edit to game-draw, and 240 consecutive frames drew it.
flan-mode.el derives from prog-mode with lisp-mode's syntax table, which is
most of the work - Flan is s-expressions, so sexp motion, paren matching,
beginning-of-defun and indentation are already right. What it adds is Flan's
own brackets ([ and { are brackets and not symbol characters, since every
binding list and every type is written with them), the characters a name may
contain, and its keywords.
flan-dev.el has no parser in it, which is what the protocol choice bought:
prin1 writes a request, read reads a reply. C-c C-k sends a buffer as one
module rather than a form at a time, because a defvar and the function using it
have to arrive in the same load or the first refers to storage that does not
exist yet. An error comes back with a location and point moves there.
Framing is in bytes and Emacs counts characters, so every length goes through
string-bytes and the process is binary. Otherwise one non-ASCII character in a
buffer puts the reply stream out of step by exactly as many bytes as the
payload has of them - a bug that reads as a corrupt protocol and only appears
for some people. test_emacs.ml drives the real client against a real daemon for
that reason: it is not the same claim as the daemon answering correctly, and a
mistake in the framing, in beginning-of-defun over Flan's syntax table, or in
the reply reader passes test_dev.ml and fails here.
