…the generator The parse trees generated by ANTLR consist only of rule nodes and do not contain information about the decisions made on alternations or quantifiers. However, tests generated by Grammarinator store such information in the form of alternative and quantifier nodes. To make these trees compatible, the current patch recreates the same structure that the generator produces in the trees obtained from parsed input. The approach reuses the grammar graph implementation of processor, therefore it requires to define a lib_dir if included grammars are stored in a separate directory. To define such directories, similarily to grammarinator-process, grammarinator-parse also supports the `--lib_dir` CLI argument. Co-authored-by: Akos Kiss <[email protected]>
