WalkthroughThis pull request introduces several enhancements to the Mermaid diagram generation package, focusing on documentation updates and consistent formatting across various diagram types. The changes include adding example test files for different diagram types (architecture, entity-relationship, flowchart, pie chart, and sequence diagrams), updating the README to document new features, and standardizing string formatting across the package. The modifications primarily involve improving code readability and providing comprehensive documentation for the Mermaid diagram generation capabilities. Changes

🧹 Nitpick comments (8)
mermaid/piechart/examples_test.go (2)
1-2: Document build constraint rationale in package documentationWhile the function comment explains why Windows is excluded, it would be helpful to document this at the package level for better visibility.
Add a package comment explaining the build constraint:
//go:build linux || darwin +// Package piechart_test contains example tests that are skipped on Windows +// due to newline formatting differences in the expected output. package piechart_test
17-25: Consider adding validation for negative valuesThe pie chart creation looks good, but consider adding validation for negative values which wouldn't make sense in a pie chart context.
mermaid/flowchart/examples_test.go (2)
39-39: Fix comment formattingAs indicated by the static analysis tool, add a space after
//.-//```mermaid +// ```mermaid🧰 Tools
🪛 golangci-lint (1.62.2)
39-39: commentFormatting: put a space between
//and comment text(gocritic)
17-30: Consider grouping related nodes visuallyThe flowchart structure is clear, but consider adding visual grouping for related nodes to enhance diagram readability.
Example addition:
DatabaseNode("D", "Database"). + SubgraphStart("data_flow", "Data Flow"). LinkWithArrowHead("A", "B"). LinkWithArrowHeadAndText("B", "D", "send original data"). LinkWithArrowHead("B", "C"). DottedLinkWithText("C", "D", "send filtered data"). + SubgraphEnd().mermaid/sequence/examples_test.go (1)
17-35: Consider adding timing indicatorsThe sequence diagram effectively shows the flow but could benefit from timing indicators for certain operations.
Example enhancement:
LoopStart("until Subaru wake up"). + Note("right of David", "Waiting 5 minutes"). SyncRequest("David", "Subaru", "Wake up!").mermaid/er/examples_test.go (2)
17-95: Consider extracting entity definitions to helper functionsThe entity definitions are quite verbose and repetitive. Consider extracting common patterns into helper functions to improve readability and maintainability.
+ func newTeacherEntity() *er.Entity { + return er.NewEntity( + "teachers", + []*er.Attribute{ + {Type: "int", Name: "id", IsPrimaryKey: true, IsUniqueKey: true, Comment: "Teacher ID"}, + {Type: "string", Name: "name", Comment: "Teacher Name"}, + }, + ) + }
97-114: Add comments explaining relationship symbolsThe relationship symbols (
||,}o, etc.) are documented inline, but consider adding a comment block explaining all possible combinations for better documentation.+ // Relationship symbols: + // || : ExactlyOneRelationship + // }o : ZeroToMoreRelationship + // |} : OneToMoreRelationship + // -- : Identifying relationship + // .. : Non-identifying relationshipmermaid/flowchart/flowchart_test.go (1)
217-220: Simplify string concatenation.The current string concatenation using
fmt.Sprintfwith//nolint:gosimplecan be simplified.Consider using a raw string literal or string builder:
- want += fmt.Sprintf("C[\"`**Node C**`\"]\n") //nolint:gosimple - want += fmt.Sprintf(" D[\"`Node\n") //nolint:gosimple - want += "D`\"]" + want += `C[\"**Node C**\"] + D[\"Node +D\"]`

🔇 Additional comments (6)
mermaid/sequence/examples_test.go (1)
16-16:
Function name doesn't match comment
The function comment refers to "ExampleSequence" but the function is named "ExampleDiagram".
Either update the comment or rename the function for consistency:
-// ExampleSequence skip this test on Windows.
+// ExampleDiagram skip this test on Windows.Likely invalid or redundant comment.

1-2: LGTM: Build tag correctly handles platform-specific test
The build tag appropriately restricts the test to Linux and Darwin platforms due to newline differences on Windows.
mermaid/er/entity_relationship_test.go (1)
136-154: LGTM: Output format is consistent and well-structured
The updated output format with consistent indentation improves readability while maintaining the correct entity relationships.
mermaid/flowchart/flowchart_test.go (2)
43-50: LGTM! Well-structured test case with proper indentation.
The expected output string correctly follows Mermaid syntax and uses consistent 4-space indentation.
74-74: LGTM! Clear and focused test case.
The test case properly validates the top-to-bottom orientation with correct Mermaid syntax.
README.md (1)
12-12: LGTM! Clear and comprehensive documentation update.
The changes effectively:
- Update the feature list to include architecture diagrams
- Clearly indicate the beta status of the feature
