[csparser-support] Fwd: SR

[Cleo S. <cle...@ya...>]

Hi Hamid,

It is the next shift or reduce. If it a shift, then SR will be the next state. If it is a reduce, then SR will be the negative of the production ID+2.

Positive SR = next state.
Negitave SR = -(productionID+2)

If it is positive, then it's the next state and I just push it onto the state stack called StateStack.
If it is negative, then I make it positive again with -(SR+2) and grab the Production from the production table p and replace the states and tokens on the stack with said production. Note that goto tables have their own ID's (gprodID). I separated them from the production table to reduce space.

Cléo

Hi everybody,
Can somebody explain to me about the CSParser::parse() function.
Specifically what is the SR variable. I need to make sense between LR(1)
and the way it's implemented in that function.

THanks
