An augmented parser can create an augmented parse tree that captures all the information in the source code as additional elements. Information included in the augmented parse tree can include whitespace, comme
A parse tree is a graphical representation of the derivation process of an input program, showing each grammar symbol used in the derivation. It can be simplified by abstracting unnecessary nodes, leading to an abstract syntax tree commonly used in compiler design. ...
a very small implementation that performs evaluation using parse tree rewrites. It sort of works, passes most tests with make check, and is overall sane, if a bit slow (similar to bash in my testing). It can be used for example as an extension language for your application, and does ...
A parse tree represents an expression, not immediately evaluated. Its virtue is that the expression can be evaluated whenever and in whatever context it is needed. The two main functions dealing with parse trees are eval, which evaluates a parse tree, an
A grammar describes the syntax of a programming language, and might be defined in Backus-Naur form (BNF). A lexer performs lexical analysis, turning text into tokens. A parser takes tokens and builds a data structure like an abstract syntax tree (AST). The parser is concerned with context:...

Fig. 1. A context-free parse tree (left) and a Boolean grammar parse DAG (right). All positive conjuncts in a Boolean grammar production must share leaves (adapted from [11]). Other useful generalizations of context-free grammars have been proposed [4], [1], [7], [8]. However, the...
