parsergeneratorer
Parsergeneratorer are software tools that automatically produce source code for a parser based on a formal grammar specification. The grammar is typically written in an extended Backus–Naur form that describes the syntax of a language or data format. The parsergeneratorer then analyze the grammar to construct parsing tables or tree-walking code, and emit code in a target programming language such as C, Java, or Python.
The concept dates back to the 1970s with the creation of YACC (Yet Another Compiler Compiler) for
Parsergeneratorer typically produce two main components from a grammar: a lexical analyser (scanner) that tokenises raw
These tools are widely used in compiler construction, language interpreters, static analysis, and data conversion utilities.
