The Parser Grammar Engine (PGE, originally the Parrot Grammar Engine) is a compiler and runtime for Raku rules for the Parrot virtual machine. PGE uses these rules to convert a parsing expression grammar into Parrot bytecode. It is therefore compiling rules into a program, unlike most virtual machines and runtimes, which store regular expressions in a secondary internal format that is then interpreted at runtime by a regular expression engine. The rules format used by PGE can express any regular expression and most formal grammars, and as such it forms the first link in the compiler chain for all of Parrot's front-end languages. When executed, the bytecode generated by PGE will parse text as described in the input rules, generating a parse tree. The parse tree can be manipulated directly, or fed into the next stage of the in order to generate an AST from which code generation can occur (if the grammar describes a programming language).

XML Parsers | Parsing XML using DOM and SAX Parsers | Edureka
( Java Training - https://www.edureka.co/java-j2ee-training-course ) A parser is a piece of program that takes a physical representation of some data and converts it into an in-memory form for the program as a whole to use. Parsers are used everywhere in software. An XML Parser is a parser

Writing a PEG Parser For Fun and Profit
Parsing Expression Grammars (PEGs) are a relatively new formalism for describing grammars suitable for automatically generating efficient parsers. I've become interested in using a PEG-generated parser as an alternative to CPython's nearly 30 year old "pgen" parser generator. This poses so

How do we make sense of a regular sentence, especially when they take us down the "garden path"? For example, when we see a sentence that starts with "The old man," most of us would expect the next word to be a verb. So when we read, "The old man the boat," we have to backtrack to re-evalu
