Analysis of grappa

Overall verdict

  • Grappa is a solid, mature parsing library for the JVM that lets developers build parsers directly in Java using a fluent, PEG-based (Parsing Expression Grammar) approach without needing a separate grammar file or code generation step.

Why this product is good

  • Uses Parsing Expression Grammars (PEG), which are unambiguous and easier to reason about than traditional context-free grammars
  • Grammars are written in pure Java as a fluent DSL, so there's no external grammar file or code-generation build step
  • Integrates naturally into existing Java/JVM projects and tooling
  • Supports parser actions, error recovery, and value stack manipulation for building ASTs
  • Successor to the popular Parboiled library, benefiting from lessons learned in that project
  • Open source and hostable/inspectable directly on GitHub

Recommended for

  • Java and JVM developers who want to build parsers without learning a separate grammar language
  • Projects needing custom domain-specific languages (DSLs) or configuration formats
  • Developers who prefer PEG semantics over ambiguous CFG-based tools like ANTLR
  • Teams that want parser logic kept inline in their codebase rather than generated
  • Prototyping and small-to-medium parsing tasks where fluent Java code is convenient

Analysis of Denemo

Overall verdict

The 10 Best Music Writing Software Programs (2022)
Using lilypond by itself is not recommended unless you are into programming-style interfaces. Denemo makes great use of the lilypond application, which produces beautiful sheet music.

  • Real-Time MIDI to LilyPond Notes for integration into text editors
    In other words, you do not need to embed this functionality into your editor, you simply need to have your editor communicate with this backend in order to have the basic MIDI input working! As I mentioned in my other post, the MIDI input functionality and features were heavily inspired by Frescobaldi and a bit by Denemo. Source: almost 3 years ago
  • โ€œCompilingโ€ Music
    I haven't seriously tried any of them, but have a look a the list at: http://lilypond.org/easier-editing.html Maybe Denemo: http://denemo.org/. - Source: Hacker News / over 4 years ago
