RE: Precompiled grammars and Start-up Actions

Or you could simply have a "reinitialize" start rule whose only purpose is to reset whatever variables you need to initialize.  After calling that start rule you could then call the "regular" start rule to parse your data.  I've done that in a couple of different grammars and it works great.

You use a specific rule to start the parse right?

What I would do is rename that rule and then create a new start rule to
initilize what needs to be initialized and then call the real start rule. Ie
if it was "start_rule" then

<<'EOF_GRAMMAR'

start_rule: { @Yet::Another::Grammar::array=(); 1}
_start_rule

_start_rule: .....
EOF_GRAMMAR

You might have to tweak a few things to get this to work out, but its
definately the apporach I would take.
