cfgrammar

cfgrammar (crate; source) reads in grammar files, processes them, and provides a convenient API for operating with them. Most users only need to think about cfgrammar to the extent that they are required to use it to specify what Yacc variant they wish to use.

cfgrammar may also be of interest to those manipulating grammars directly, or who wish to use custom types of parsers. Note that cfgrammar's API should be considered semi-stable at best. As the needs of other parts of grmtools change, cfgrammar tends to have to change too. Since it is unlikely to have few direct users, the consequences of changing the API are relatively slight.
