renv is an R dependency management toolkit that enables project-level library isolation and reproducibility. It tracks package versions in a lockfile and can restore exact library states across machines or over time, making R projects portable and consistent.
Transcribe Parsing Expression Grammar into a parser written in Java.
...In addition, PEG can define parsers with integrated lexing.
Unlike some existing parser generators for PEG, the tool does not produce a complex and storage-hungry "packrat parser", but a collection of transparent recursive procedures.
The tool can handle left recursion.
An integral feature of "Mouse" is the mechanism for specifying semantics (also in Java). This makes "Mouse" a convenient tool if one needs an ad-hoc language processor. Being written in Java, the processor is operating-system independent.
...
PackCC is a packrat parser generator for C, which can handle PEGs (Parsing Expression Grammars) very efficiently, and can support direct and indirect left-recursive grammar rules.
A backtracking (non-packrat) parser generator for parsing expression grammars. The parsers are generated at run-time using the LLVM JIT compilation engine.
