PEG(1) PEG(1) NAME peg, leg - parser generators SYNOPSIS peg [-hvV -ooutput] [filename ...] leg [-hvV -ooutput] [filename ...] DESCRIPTION peg and leg are tools for generating recursive-descent parsers: pro- grams that perform pattern matching on text. They process a Parsing Expression Grammar (PEG) [Ford 2004] to produce a program that recog- nises legal sentences of that grammar. peg processes P
peg/leg â recursive-descent parser generators for C peg and leg are tools for generating recursive-descent parsers: programs that perform pattern matching on text. They processes a Parsing Expression Grammar (PEG) [Ford 2004] to produce a program that recognises legal sentences of that grammar. peg processes PEGs written using the original syntax described by Ford; leg processes PEGs written using
Handwritten Parsers & Lexers in Go In these days of web apps and REST APIs it seems that writing parsers is a dying art. You may think parsers are a complex undertaking only reserved for programming language designers but Iâd like to dispel this idea. Over the past few years Iâve written parsers for JSON, CSS3, and database query languages and the more that I write parsers the more that I love the
Introducing ciso8601: A fast ISO8601 date time parser for Python Project link: https://github.com/closeio/ciso8601 Sometimes it's the little things that make web apps faster. We noticed that loading leads and opportunity view pages in Close wasn't as fast as we wanted it to be in some cases, so we pulled up the profiler. To our surprise, a large portion of time was spent parsing date times, someti

Iâm pleased to introduce the third generation of my attoparsec parsing library. With a major change to its internals, it is both faster and more powerful than previous versions, while remaining backwards compatible. Comparing to C Letâs start with a speed comparison between the hand-written C code that powers Node.jsâs HTTP parser and an idiomatic Haskell parser that uses attoparsec. There are goo

MBSP is a text analysis system based on the TiMBL and MBT memory based learning applications developed at CLiPS and ILK. It provides tools for Tokenization and Sentence Splitting, Part of Speech Tagging, Chunking, Lemmatization, Relation Finding and Prepositional Phrase Attachment. The general English version of MBSP has been trained on data from the Wall Street Journal corpus. Download MBSP for P
We are sorry, but the site you are looking for no longer exists Wikispaces was founded in 2005 and has since been used by educators, companies and individuals across the globe. Unfortunately, the time has come where we have had to make the difficult business decision to end the Wikispaces service. We first announced the site closure in January 2018, through a site-wide banner that appeared to all
In preparation for my PyCon talk on HTML I thought Iâd do a performance comparison of several parsers and document models. The situation is a little complex because thereâs different steps in handling HTML: Parse the HTML Parse it into something (a document object) Serialize it Some libraries handle 1, some handle 2, some handle 1, 2, 3, etc. For instance, ElementSoup uses ElementTree as a documen
Yapps (Yet Another Python Parser System) is an easy to use parser generator that is written in Python and generates Python code. Although there are several parser generators already available for Python, I had different goals, including learning about recursive descent parsers. Yapps is simple, is easy to use, and produces human-readable parsers. It is not fast, powerful, or particularly flexible.
