Nqp

Not Quite Perl (NQP) is a high-level programming language designed as part of the Perl 6 project to enhance language implementation on virtual machines. Aimed at generating domain-specific languages (DSLs), NQP shares similar syntax with Perl 6 but does not intend to replace it. Compiling to bytecode, NQP enables execution on various back-end virtual machines supporting its compiler toolchain, acting as an intermediary for translating higher-level languages into efficient machine code tailored for specific platforms or environments.

NQP's development was led by the teams and contributors within the Perl 6 community, emerging from a collaborative effort to create a high-level programming language that facilitates DSL creation and serves as an intermediary representation in compiling bytecode. This role allows developers to write more abstract code while generating optimized machine code for specific platforms, bridging the gap between higher-level languages and lower-level target environments. Its emergence addresses the need for tools that improve language implementation and support custom DSL development within the Perl 6 ecosystem.

As a versatile intermediary representation language, NQP competes with tools like Raku (formerly known as Perl 6), ANTLR, and Spoofax that also offer robust frameworks for language implementation and DSL creation. However, NQP's distinct focus on compiling to bytecode sets it apart by enabling seamless translation of higher-level languages into efficient machine code optimized for various execution environments. This emphasis on interoperability and performance optimization makes NQP valuable in developing domain-specific languages within diverse coding practices while maintaining efficiency across different platforms.
