I was looking at the q2c documentation so I can write the GLM syntax.
It says this:
grammar-rules ::= command-name opt-prefix : subcommands .
command-name ::= ID
::= ( ID )
subcommands ::= subcommand
::= subcommands ; subcommand
...so, after the command name, I enter a list of subcommand names.
The problem is that GLM's syntax differs from that of other procedures.
It looks like this:
GLM dependent variable [BY factor list [WITH covariate list]] ...
so the first token after the command name is a variable name. I'm not
sure how to write the q2c rules for that.
I thought about adding an optional VARIABLE subcommand, then assuming
if it isn't there that the first token goes with the unused
subcommand, but this approach seems like a kludge.
Does this mean I need to write a custom parser? I hope not.
I don't know much about lexer and q2c, so the answer to my questions
might be 'RTFM'. That's okay, but please mention which FM to R.
