logparser is a flexible command line utility that was initially written by Gabriele Giuseppini, [1] a Microsoft employee, to automate tests for IIS logging.It was intended for use with the Windows operating system, and was included with the IIS 6.0 Resource Kit Tools.
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 ...
The Parsec parser library uses monads to combine simpler parsing rules into more complex ones, and is particularly useful for smaller domain-specific languages. [ 14 ] xmonad is a tiling window manager centered on the zipper data structure , which itself can be treated monadically as a specific case of delimited continuations .
PLY is a parsing tool written purely in Python. It is, in essence, a re-implementation of Lex and Yacc originally in C-language . It was written by David M. Beazley .
Matplotlib is a plotting package for the free programming language Python. Its pyplot interface is procedural and modeled after MATLAB, while the full Matplotlib interface is object-oriented. Python and Matplotlib are cross-platform, and are therefore available for Windows, OS X, and the Unix-like operating systems like Linux and FreeBSD.
A predictive parser is a recursive descent parser that does not require backtracking. [3] Predictive parsing is possible only for the class of LL( k ) grammars, which are the context-free grammars for which there exists some positive integer k that allows a recursive descent parser to decide which production to use by examining only the next k ...
The Packrat parser is a type of parser that shares similarities with the recursive descent parser in its construction. However, it differs because it takes parsing expression grammars (PEGs) as input rather than LL grammars .
In computer programming, a parser combinator is a higher-order function that accepts several parsers as input and returns a new parser as its output. In this context, a parser is a function accepting strings as input and returning some structure as output, typically a parse tree or a set of indices representing locations in the string where parsing stopped successfully.
