Choose cceval if…
- License: cceval is Apache-2.0, lever is MIT.
- Tags unique to cceval: benchmark, code-completion, cross-file, evaluation-tool.
- You need to evaluate the performance of cross-file code completion systems that can handle multiple programming languages simultaneously
When NOT to use cceval
- Your evaluation needs are focused solely on single-file or intralingual code completion benchmarks
- You require real-time data access or live updates; cceval provides pre-packaged datasets that need to be manually obtained and uncompressed
Choose lever if…
- License: lever is MIT, cceval is Apache-2.0.
- Requirements: All of the pipelines have been tested on Linux machines only, requiring possibly custom `tree-sitter` parsers for other platforms..
- Tags unique to lever: code verification, execution based verification, language-to-code.
- Also covers Model Training.
- When the development team needs to verify accuracy of generated code from language inputs based on execution, and has access to Linux machines to ensure seamless functionality.
When NOT to use lever
- Avoid Lever if developing in an environment other than Linux as it requires the use of tree-sitter parsers, which may not be compatible with your system.
- Do not choose Lever if you seek a tool that does not require setting up a conda environment and installing specific dependencies to operate.
