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 ...

However, parser generators for context-free grammars often support the ability for user-written code to introduce limited amounts of context-sensitivity. (For example, upon encountering a variable declaration, user-written code could save the name and type of the variable into an external data structure, so that these could be checked against ...
English: An abstract syntax tree for the following pseudocode, implementing the Euclidean algorithm to find the greatest common divisor of a and b: while b ≠ 0 : if a > b : a := a - b else : b := b - a return a

Tree Description Language (TreeDL) is a computer language for description of strictly-typed tree data structures and operations on them. The main use of TreeDL is in the development of language-oriented tools (compilers, translators, etc.) for the description of a structure of abstract syntax trees. Tree description can be used as

An abstract syntax tree (AST) is a data structure used in computer science to represent the structure of a program or code snippet. It is a tree representation of the abstract syntactic structure of text (often source code ) written in a formal language .
