From looking through the relevant snippets, I decided to make the following modifications:
| File Path | Proposed Changes |
|---|---|
melpoi/sql/analyzer.py |
Modify melpoi/sql/analyzer.py with contents: • Add a try-except block around the import statement for Graphviz at the top of the file. In the except block, set a flag variable (e.g., graphviz_available) to False. • Modify the plot_inline method to check the graphviz_available flag before attempting to use Graphviz. If Graphviz is not available, the method should return a message indicating that Graphviz is not installed and that visualization is not available. |
tests/sql/test_sql.py |
Modify tests/sql/test_sql.py with contents: • Add a new test function (e.g., test_SqlAnalyzer_no_graphviz) that tests the functionality of the SqlAnalyzer class when Graphviz is not installed. This function should create an instance of the SqlAnalyzer class and call its methods, verifying that they behave as expected and do not raise any errors. |
examples/sql/README.md |
Modify examples/sql/README.md with contents: • Add a new section about the optional Graphviz dependency. This section should explain that while the melpoi library can function without Graphviz, installing it enables the visualization of SQL dependencies. |
Step 3: 📝 Planning
I have created a plan for writing the pull request. I am now working my plan and coding the required changes to address this issue. Here is the planned pull request:
Fix GraphViz dependencies in SqlAnalyzer class
sweep/fix-graphviz-dependencies
Description
This PR fixes the issue with GraphViz dependencies in the SqlAnalyzer class of the melpoi library. The SqlAnalyzer class uses GraphViz for visualizing SQL dependencies, but GraphViz is not a mandatory dependency. Currently, if GraphViz is not installed, the SqlAnalyzer class fails. This PR modifies the SqlAnalyzer class to check if GraphViz is installed before attempting to use it. If GraphViz is not available, the class will still function but without the ability to visualize SQL dependencies.
Summary of Changes
- Modified the SqlAnalyzer class to check if GraphViz is installed before attempting to use it.
- Added a flag variable to indicate whether GraphViz is available.
- Modified the plot_inline method in the SqlAnalyzer class to only attempt to use GraphViz if it is available.
- Added tests to verify that the SqlAnalyzer class behaves as expected when GraphViz is not installed.
- Updated the README to inform users about the optional GraphViz dependency.
Please review and merge this PR. Thank you!

Step 5: 🔁 Code Review
Here are my self-reviews of my changes at sweep/fix-graphviz-dependencies.
Here is the 1st review
Hello, great job on making the SQLAnalyzer class function without Graphviz installed. However, there are a few changes that need to be made:
- In the
tests/sql/test_sql.pyfile, thetest_SqlAnalyzer_no_graphviztest will only pass if Graphviz is not installed on the system where the test is run. To make the test more robust, it could be modified to mock the import of Graphviz, so that it can simulate both the presence and absence of Graphviz regardless of the actual installation status on the system. This will ensure that the test is always valid, regardless of the environment it's run in.Keep up the good work!
I finished incorporating these changes.
