Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
@lezer/cpp is built on top of Lezer, which has a unique API and requires familiarity with JavaScript patterns.
The project relies heavily on the broader Lezer ecosystem for documentation, which can be sparse in specific areas relevant to C++ parsing.
Version updates often introduce API changes that require significant refactoring of existing codebases using @lezer/cpp.
Parsing and manipulating large or complex C++ files can lead to performance bottlenecks, especially in real-time applications.
