Re: How to reload Wisent grammar?

Hello Gracjan,

Personally I have found that you can change the grammar, recompile and test
it as follows:

1) In the grammar file: C-u C-c C-c to fully recompile the parser
automaton. You'll often need to repeat this twice before the new grammar is
compiled and *automatically evaluated*
2) In the test file: C-x C-v to revert the buffer and parse it according to
the latest grammar.

Unfortunately, this approach works a number of times before it all starts
misbehaving.

It seems to me like the more recent releases of CEDET are more resilient,
but if you're actively experimenting with the grammar and its
mode-local-overrides you'll eventually witness some weird behaviour that
wouldn't affect a grammar compiled in a fresh instance of Emacs.

Therefore in my experience the best approach would be that of writing a
build script which compiles the grammar and opens it in a fresh instance of
emacs. Better yet if the grammar if you have a number of unit tests to
check the tags produced by the grammar.

Regards,
Andrea
