CEDARScript (Concise Examination, Development, And Refactoring Script) is a domain-specific language designed to improve how AI coding assistants interact with codebases and communicate their code modification intentions. It provides a standardized way to express complex code modification and analysis operations, making it easier for AI-assisted development tools to understand and execute these tasks.
- Install Aider with CEDARScript via this command below:
pip install --upgrade --force-reinstall \
git+https://github.com/elifarley/aider@cedarscript \
aider-chat- Now, simply use the
--edit-formatswitch and selectcedarscript:
aider --edit-format cedarscriptTL;DR: You can get higher success rates when refactoring large files, when compared to other edit formats.
- Higher Success Rates: Significantly improves the performance of AI models in code refactoring tasks.
- Cost-Effective Performance: Enables more affordable models to compete with top-tier options.
- Standardized Communication: Provides a consistent format for AI-code interaction in coding tasks.
- Enhanced Accuracy: Reduces errors and improves the quality of AI-generated code modifications.
CEDARScript has shown remarkable improvements in AI model performance for code refactoring:
| Model | Format | Pass Rate | Well-Formed Cases | Syntax Errors | Indentation Errors | Cost | Avg. Time per case |
|---|---|---|---|---|---|---|---|
| Gemini 1.5 PRO | CEDARScript | 77.5% | 86.5% | 4 | 3 | 26.2 | 29 |
| Gemini 1.5 Flash | CEDARScript | 76.4% | 94.4% | 3 | 5 | 0.68 | 14.7 |
| Claude 3.5 Sonnet | diff | 64.0% | 76.4% | n/a | n/a | n/a | n/a |
| Gemini 1.5 PRO | diff-fenced | 49.4% | 7.9% | 21 | 93 | 28.3 | 110.1 |
- Gemini 1.5 PRO with CEDARScript outperformed both its diff-fenced format and Claude 3.5 Sonnet.
- Most remarkably, the more cost-effective Gemini 1.5 Flash model, using CEDARScript, outperformed Claude 3.5 Sonnet.
- It goes to show that even a more affordable model can surpass top-tier competitors when equipped with the right tools.
This suggests that CEDARScript can level the playing field, enabling more accessible AI models to compete with and even exceed the capabilities of more expensive options in certain coding tasks.
- 48% of tests (43 total) showed improvements
- 103% increase in Pass 1 success rate (75 tests)
- Test duration reduced by 93% (from 5:17:26 to 0:25:17)
- Token efficiency greatly improved:
- Sent tokens: -37% (7.59M)
- Received tokens: -96% (180K)
- Error reduction:
- Error outputs: -94% (35 total)
- Malformed outputs: -94% (6 cases)
- Syntax errors: -85% (3 cases)
- Indent errors eliminated (100% reduction)

Improvements:
36 tests that previously failed now pass. This is a substantial improvement, indicating that CEDARScript is more effective in correctly extracting methods from classes across a wide range of codebases.
Notable improvements include:
analyzer_cli_DebugAnalyzer__make_source_table: Suggests better handling of debug-related code refactoring.autodetector_MigrationAutodetector__trim_to_apps: Indicates improved capability in refactoring Django migration-related code.cuda_cpp_scheduling_CUDACPPScheduling__can_fuse_epilogue_impl: Shows better performance in handling complex CUDA-related code.triton_TritonScheduling_define_kerneland triton_TritonScheduling_generate_node_schedule: Demonstrates improved capability in refactoring GPU computing-related code.
Minor Improvements:
3 tests showed minor improvements, such as checks_BaseModelAdminChecks__check_autocomplete_fields_item, suggesting
slight enhancements in handling Django admin-related code.
Regressions:
7 tests that previously passed now fail. While concerning, it's a relatively small number compared to the improvements.
Notable regressions include:
feedgenerator_Atom1Feed_add_item_elements: Suggests potential issues with refactoring feed generation code.generic_bsd_GenericBsdIfconfigNetwork_parse_inet_line: Indicates challenges in refactoring network-related parsing code.introspection_DatabaseIntrospection__parse_column_or_constraint_definition: Shows difficulties in handling database schema introspection code.
Stability:
30 tests remained stable and passing, indicating that CEDARScript maintained performance in many areas, including various
Django commands, database operations, and utility functions.
13 tests remained stable but failing, suggesting that some challenging areas were not addressed by either format.
These include complex operations like symbolic_shapes_ShapeEnv_bind_symbols and reshaping_BaseReshapingTests_test_unstack.
Analysis by Domain:
- Web Frameworks (e.g., Django): Generally improved, with better handling of model admin checks, configuration, and database operations.
- Data Science and ML: Mixed results. Improvements in areas like clustering operations (
clustering_ops_KMeans__mini_batch_training_op) and data frame handling, but persistent issues in some reshaping operations. - System-level Operations: Some improvements (e.g.,
distribution_DistributionFiles_parse_distribution_file_SUSE) but also regressions (e.g.,generic_bsd_GenericBsdIfconfigNetwork_parse_inet_line). - GPU and High-Performance Computing: Significant improvements, especially in
CUDAandTriton-related code.
Interpretation:
CEDARScript appears more effective in handling complex code structures, especially in areas related to web frameworks, data processing, and high-performance computing. It shows improved capability in understanding class contexts and correctly extracting methods across various domains. However, it may introduce new challenges in certain specific areas, possibly due to its different approach to code manipulation.
Areas for Further Investigation:
Understanding why certain tests regressed (e.g., feedgenerator_Atom1Feed_add_item_elements) could provide insights for improvement.
Analyzing the stable failing tests (e.g., symbolic_shapes_ShapeEnv_bind_symbols) to see if CEDARScript can be enhanced
to address these persistent issues.
Conclusion:
- The introduction of CEDARScript appears to be a significant improvement for the task of extracting methods from classes.
- It shows particular strength in handling complex codebases, especially those related to web frameworks, data processing, and high-performance computing.
- However, care should be taken to address the areas where regressions occurred, particularly in system-level operations and certain parsing tasks.
- The consistent performance across various domains suggests that CEDARScript offers a more robust and versatile approach to code refactoring.
This analysis indicates that CEDARScript is a promising enhancement to Aider, offering more accurate and comprehensive method extraction capabilities across a wide range of codebases. However, it also highlights the need for continued refinement, especially in areas where regressions were observed.
