Request: grammar tokens documentation.

[jcrodriguez1989]

I am working on an R code optimizer project, in which I am trying to use as much as possible R base packages.
The utils::getParseData functions is being really useful for my tasks. However, it is getting hard to decipher what each token means. So far, the best I could find was the grammar definition found in this repo.
@halpo , @romainfrancois , @jimhester and @dmurdoch as you were working with parsing-related projects, could any of you provide me of documentation regarding to which R expression each token maps?

Sorry for the inconvenience.
Thank you very much!
Rodriguez, Juan Cruz

You should look at the grammar definition in the source for the parser in src/main/gram.y (current version in https://svn.r-project.org/R/trunk/src/main/gram.y) for all the definitions. As far as I know that's the only documentation. Duncan Murdoch

If you think it is the only documentation available, then it must be.
Thank you very much!
