The R version of dparser is meant to be used as a package library whereyou link the C parser to an arbitrary grammer parsed in R. This is whatis used inrxode2()

There are a few differences between the R dparser port and the standarddparser:

• The R version uses R memory managment instead of C’s memory managmenti.e. malloc

• The R version is never called from the command line, so all commandline interface is removedarg.c

• The R version doesn’t exit from the command (killing R), but errorsout in R.

• All outputs are using R’s output interface instead of printing tostdout, orstderr.

• Some convience functions are added to translate (and maybe parse)grammers within R.

• There is currently some fixes for un-sanitized behaviors that are notin the upstream dparser

• Currently there isn’t an interface to use binary grammars
