Hello,
Is the Vim Script grammar documented anywhere? I'd like to write a parser.
(Searching for "vim script grammar/parser" brings up grammars/parsers
written _in_ vim script, unfortunately...)
Thanks!

In addition to all good answers already present in this thread, I'll add
the following:
- AFAIK, a "formal grammar" for Vim script has never been written (and
if you start writing one now, it will quite possibly be obsolete by the
time you finish writing it, because new features will have been added in
the meantime). The sum total of the help files constitute a sort of
"unformal" but detailed grammar which is quite good enough for users of Vim.
What I've seen that comes closest to a formal grammar for _part_ of Vim
script is Section 2 of pattern.txt (see :help pattern). It is the single
section in the whole help which I find the most abtruse, that is the
least understandable for the common folk.
- IMHO, the "best" interpreter for Vim script language will always be
Vim itself. Why? Because any other "imitation" interpreter will be hard
put to implement bug fixes and new features as fast as Vim does, and any
user of such an interpreter is bound to find it deficient compared to
Bram's masterwork.
- If you're on Windows, you can use the OLE interface to communicate
with Vim, see :help if_ole.txt
- On other platforms, it's harder to have an interactive Vim running as
if it were part of your application, but you can run "gvim -f filename"
as a subprocess and continue when the subprocess terminates. (Without -f
or the equivalent --nofork you would restart much too early, see :help
gui-fork)
Best regards,
Tony.
