2. Parse tree - Wikipedia

   en.wikipedia.org/wiki/Parse_tree

   A simple parse tree. A parse tree is made up of nodes and branches. [4] In the picture the parse tree is the entire structure, starting from S and ending in each of the leaf nodes (John, ball, the, hit). In a parse tree, each node is either a root node, a branch node, or a leaf node. In the above example, S is a root node, NP and VP are branch ...

   Tree-sitter parsers have been written for these languages and many others. [11] GitHub uses Tree-sitter to support in-browser symbolic code navigation in Git repositories. [12] Tree-sitter uses a GLR parser, a type of LR parser. [13] [14] [12] Tree-sitter was originally developed by GitHub for use in the Atom text editor, where it was first ...

[citation needed] [6] ANTLR can generate lexers, parsers, tree parsers, and combined lexer-parsers. Parsers can automatically generate parse trees or abstract syntax trees, which can be further processed with tree parsers. ANTLR provides a ...
