lezer

Lezer is a Dutch noun meaning a person who reads, i.e., a reader. In everyday language it refers to the audience of books, newspapers, magazines, or other written material. The term is commonly used in media to describe readers collectively or individually.

Etymology and related terms: Lezer is formed from the verb lezen (to read) with the agent suffix -er, producing a word that signifies the doer of the action. It is cognate with the German Leser and the English word reader.

Usage in Dutch: Lezers as a group are frequently referenced in journalism and publishing. Compounds include lezersbrief, a brief written by a reader; lezerspubliek, the readership or audience of a publication; and phrases like lezers van een krant, meaning readers of a newspaper.

In computing: Lezer is also the name of a parser framework used to build incremental parsers for editor tooling, notably in the CodeMirror 6 project. It provides a system for defining languages through grammars that generate parsers in TypeScript, enabling features such as syntax highlighting, code folding, indentation, and error reporting in code editors.

Overview: The two primary uses—an ordinary Dutch noun for a reader and a software project name—are distinct, connected mainly by the shared underlying idea of reading or interpreting input. Lezer as a linguistic term focuses on people who read, while Lezer as a software term refers to a tool that reads and analyzes source code.
