    Walkthrough

    The changes in the pull request focus on the sdrf_schema.py file, specifically within the SDRFSchema class. Modifications include renaming the variable index to assay_index for clarity, refining the validation logic for column order, and enhancing error messages. The control flow in the validate_columns_order method has been adjusted to improve readability and robustness, ensuring that the validation for "assay name," "comment," "technology type," and "factor value" columns is more explicit and reliable.

    Changes

    File Change Summary
    sdrf_pipelines/sdrf/sdrf_schema.py - Renamed variable index to assay_index in validate_columns_order method.
    - Adjusted control flow in validate_columns_order to use enumerate for better readability.
    - Refined validation logic for column order regarding "assay name," "comment," and "technology type."
    - Improved handling of "factor value" columns for correct positioning.
    - Minor adjustments to error messages for clearer feedback.

    Objective Addressed Explanation
    Ensure "technology type" cannot precede "assay name" (#177)

    Poem

    In the schema where data flows,
    A rabbit hops where validation grows.
    With clearer paths and names so bright,
    The columns dance in order, just right!
    Hooray for changes, let’s cheer and play,
    For a robust schema, hip-hip-hooray! 🐇✨

    Here are some key observations to aid the review process:

    ⏱️ Estimated effort to review: 2 🔵🔵⚪⚪⚪
    🧪 No relevant tests
    🔒 No security concerns identified
    ⚡ Recommended focus areas for review

    Logic Change
    The condition for "technology type" column has been moved from the first if statement to the second. This changes the validation logic and may affect the behavior of the function.

    Performance Improvement
    The use of enumerate instead of list.index improves performance, but the assay_index is still calculated using list.index. Consider using enumerate for this as well.

    Enhancement
    Simplify column order validation logic using a dictionary-based approach for improved maintainability and extensibility

    Consider using a dictionary to map column types to their allowed positions relative
    to the "assay name" column. This approach would simplify the logic and make it
    easier to maintain and extend in the future.

    sdrf_pipelines/sdrf/sdrf_schema.py [286-293]

    -if "comment" in column and idx < assay_index:
    -    error_message = "The column " + column + " cannot be before the assay name"
    -    error_columns_order.append(LogicError(error_message, error_type=logging.ERROR))
    -if (
    -    "characteristics" in column or ("material type" in column and "factor value" not in column)
    -    or "technology type" in column) and idx > assay_index:
    -    error_message = "The column " + column + " cannot be after the assay name"
    -    error_columns_order.append(LogicError(error_message, error_type=logging.ERROR))
    +column_rules = {
    +    "comment": {"position": "after", "error": "cannot be before"},
    +    "characteristics": {"position": "before", "error": "cannot be after"},
    +    "material type": {"position": "before", "error": "cannot be after"},
    +    "technology type": {"position": "before", "error": "cannot be after"}
    +}
    +for rule, details in column_rules.items():
    +    if rule in column:
    +        if (details["position"] == "after" and idx < assay_index) or \
    +           (details["position"] == "before" and idx > assay_index):
    +            error_message = f"The column {column} {details['error']} the assay name"
    +            error_columns_order.append(LogicError(error_message, error_type=logging.ERROR))
    • Apply this suggestion
    Suggestion importance[1-10]: 7

    Why: The suggestion to use a dictionary for mapping column types to their allowed positions can simplify the logic and improve maintainability. However, it introduces a new structure that may require additional testing to ensure it behaves as expected.

    7
    Utilize f-strings for more efficient and readable string formatting in error messages

    Use f-strings for string formatting instead of string concatenation to improve
    readability and performance.

    sdrf_pipelines/sdrf/sdrf_schema.py [287-292]

    -error_message = "The column " + column + " cannot be before the assay name"
    +error_message = f"The column {column} cannot be before the assay name"
     ...
    -error_message = "The column " + column + " cannot be after the assay name"
    +error_message = f"The column {column} cannot be after the assay name"
    Suggestion importance[1-10]: 6

    Why: Using f-strings improves readability and performance slightly, making the code more modern and easier to understand. This is a minor enhancement but beneficial for code clarity.

    6
    Best practice
    Use more descriptive variable names to enhance code readability and self-documentation

    Consider using a more descriptive variable name instead of temp to improve code
    readability and maintainability.

    sdrf_pipelines/sdrf/sdrf_schema.py [297-299]

     if factor_tag:
    -    temp = []
    -    error = []
    +    factor_columns = []
    +    factor_errors = []
    • Apply this suggestion
    Suggestion importance[1-10]: 5

    Why: Renaming variables to more descriptive names like factor_columns and factor_errors enhances readability and maintainability. This is a good practice, though it has a minor impact on the overall functionality.

    Line range hint 295-302: Improve Variable Naming for Clarity.

    The variables temp and error are generic and could be renamed to more descriptive names to enhance code clarity.

    For example:

    • Rename temp to factor_columns.
    • Rename error to misplaced_columns.

    Apply this diff to update the variable names:

     if factor_tag:
    -    temp = []
    -    error = []
    +    factor_columns = []
    +    misplaced_columns = []
         for column in cnames[factor_index:]:
    -        if "comment" in column or "characteristics" in column:
    -            error.extend(temp)
    -            temp = []
    +        if "comment" in column or "characteristics" in column:
    +            misplaced_columns.extend(factor_columns)
    +            factor_columns = []
             elif "factor value" in column:
    -            temp.append(column)
    +            factor_columns.append(column)
         if len(error):
    -        error_message = "The following factor column should be last: {}".format(", ".join(error))
    +        error_message = "The following factor columns should be last: {}".format(", ".join(misplaced_columns))
             error_columns_order.append(LogicError(error_message, error_type=logging.ERROR))

    283-283: Variable Renaming Enhances Clarity: Change Approved.

    Renaming index to assay_index improves code readability by explicitly indicating that this index corresponds to the "assay name" column.


    285-285: Use of enumerate Improves Code Efficiency and Readability.

    Switching to enumerate for iterating over column names simplifies index tracking and enhances code readability.


    286-287: Validation Logic Correctly Enforces "comment" Columns Position.

    The condition properly checks that "comment" columns do not appear before the "assay name" column, ensuring the column order is validated as per the schema.


    291-292: Inclusion of "technology type" in Order Validation Strengthens Schema Enforcement.

    Adding "technology type" to the validation logic ensures that this column is not positioned after the "assay name," aligning with the intended column order.

    🛠️ Refactor suggestion

    Refactor Conditional Statement for Improved Readability.

    The complex conditional can be refactored for better readability by restructuring the conditions.

    Consider reorganizing the condition:

    if idx > assay_index and (
        "characteristics" in column
        or ("material type" in column and "factor value" not in column)
        or "technology type" in column
    ):

    This places the index check upfront and groups the column-related conditions together, making the logic clearer.

    289-289: Use f-strings for constructing error messages

    For improved readability and consistency, consider using f-strings when constructing error messages throughout the validation logic.

    Apply these diffs:

    # Line 289
    -            error_message = "The column " + column + " cannot be before the assay name"
    +            error_message = f"The column {column} cannot be before the assay name"
