A parse tree or parsing tree (also known as a derivation tree or concrete syntax tree) is an ordered, rooted tree that represents the syntactic structure...

information.[citation needed] Some parsing algorithms generate a parse forest or list of parse trees from a string that is syntactically ambiguous. The term is...

abstract syntax trees from concrete syntax trees, traditionally designated parse trees. Parse trees are typically built by a parser during the source...

parsers: SLR parsers, LALR parsers, canonical LR(1) parsers, minimal LR(1) parsers, and generalized LR parsers (GLR parsers). LR parsers can be generated...

computing, Tree-sitter is a parser generator and incremental parsing library. It is used to parse source code into concrete syntax trees usable in compilers...

practice, e.g. by a recursive descent parser. Unlike CFGs, PEGs cannot be ambiguous; a string has exactly one valid parse tree or none. It is conjectured that...

Top-down parsing in computer science is a parsing strategy where one first looks at the highest level of the parse tree and works down the parse tree by using...

s,a] = <p,b,c> if P[n,1,1] > 0 then find the parse tree by retracing through back return the parse tree else return "not a member of language" In informal...

in one forward pass over the text, without backing up. The parser builds up the parse tree incrementally, bottom up, and left to right, without guessing...

recogniser can be modified to create a parse tree as it recognises, and in that way can be turned into a parser. In the following descriptions, α, β, and...
