Passing additional parameters to %merge function

[Michel Rosien]

Hello,

 

I am using the %parse-param option of bison to pass additional parameters to the parse function.

I pass a pointer to an instance of a class which holds the parser environment

(because i'm using %pure-parser)

 

I am also using the %glr-parser option and I use %merge to merge the parsers. However I cannot find a way to pass the additional parameter to the %merge function and I need the parser environment in the merging function.

 

Currently I "solve" this by making a global variable, but this is ofcourse not good since it defies the purpose of a pure parser

 

Regards,

 

Michel
