src/antlr3treeparser.c(3)

📦 version 3.4, in fedora 43

🌸 NAME 🌸

src/antlr3treeparser.c — bestie, this is the implementation of the tree parser plus all the overrides for the base recognizer. 💖

✨ SYNOPSIS ✨

#include <antlr3treeparser.h>

🦋 Functions 🦋

  • ANTLR3_API void antlr3MTNExceptionNew (pANTLR3_BASE_RECOGNIZER recognizer) — makes a brand new Mismatched Tree Nde Exception and drops it into the recognizer's exception stack. 💅
  • ANTLR3_API pANTLR3_TREE_PARSER antlr3TreeParserNewStream (ANTLR3_UINT32 sizeHint, pANTLR3_COMMON_TREE_NODE_STREAM ctnstream, pANTLR3_RECOGNIZER_SHARED_STATE state) — yes, it's the one that allocates the tree parser memory (more on that below, keep reading 🫶).
  • static void freeParser (pANTLR3_TREE_PARSER parser) — the little cleanup gremlin.
  • static void * getCurrentInputSymbol (pANTLR3_BASE_RECOGNIZER recognizer, pANTLR3_INT_STREAM istream) — grabs the current input symbol.
  • static void * getMissingSymbol (pANTLR3_BASE_RECOGNIZER recognizer, pANTLR3_INT_STREAM istream, pANTLR3_EXCEPTION e, ANTLR3_UINT32 expectedTokenType, pANTLR3_BITSET_LIST follow) — the "oops we're missing a symbol" handler.
  • static pANTLR3_COMMON_TREE_NODE_STREAM getTreeNodeStream (pANTLR3_TREE_PARSER parser) — returns a pointer to the input stream. that's it, that's the job ✨
  • static void mismatch (pANTLR3_BASE_RECOGNIZER recognizer, ANTLR3_UINT32 ttype, pANTLR3_BITSET_LIST follow) — an override for the standard base recognizer mismatch function, because we've got DOWN/UP nodes chillin' in the stream with no line info, and also we wanna change up the exception type. 💀
  • static void setTreeNodeStream (pANTLR3_TREE_PARSER parser, pANTLR3_COMMON_TREE_NODE_STREAM input) — sets the input stream and resets the parser.

👑 Detailed Description 👑

Implementation of the tree parser and overrides for the base recognizer. periodt. ✨

💜 void mismatch (pANTLR3_BASE_RECOGNIZER recognizer, ANTLR3_UINT32 ttype, pANTLR3_BITSET_LIST follow) [static]

Override for standard base recognizer mismatch function as we have DOWN/UP nodes in the stream that have no line info, plus we want to alter the exception type. lowkey the drama of it all 😭
