-# Jison to Chevrotain Parser Conversion Instructions
-
-## Overview
-This guide provides step-by-step instructions for converting a Jison-based parser to Chevrotain, specifically for the flowchart parser located at `src/diagrams/flowchart/parser/flow.jison`.
-
-## Critical Requirements
-- **Multi-mode lexing is MANDATORY** - This is crucial for mirroring Jison's lexical states
-- Preserve the existing parser structure to maintain compatibility
-- All original test cases must be included in the converted test suite
-- Minimize changes to test implementation
-
-## Understanding Jison States
-The Jison parser uses multiple lexical states defined with `%x`:
-- string, md_string, acc_title, acc_descr, acc_descr_multiline
-- dir, vertex, text, ellipseText, trapText, edgeText
-- thickEdgeText, dottedEdgeText, click, href, callbackname
-- callbackargs, shapeData, shapeDataStr, shapeDataEndBracket
-
-### State Management in Jison:
-- `this.pushState(stateName)` or `this.begin(stateName)` - Enter a new state
-- `this.popState()` - Return to the previous state
-- States operate as a stack (LIFO - Last In, First Out)
-
-## Conversion Process
-
-### Phase 1: Analysis
-1. **Study the Jison file thoroughly**
-   - Map all lexical states and their purposes
-   - Document which tokens are available in each state
-   - Note all state transitions (when states are entered/exited)
-   - Identify semantic actions and their data transformations
-
-2. **Create a state transition diagram**
-   - Document which tokens trigger state changes
-   - Map the relationships between states
-   - Identify any nested state scenarios
-
-### Phase 2: Lexer Implementation
-1. **Set up Chevrotain multi-mode lexer structure**
-   - Create a mode for each Jison state
-   - Define a default mode corresponding to Jison's INITIAL state
-   - Ensure mode names match Jison state names for clarity
-
-2. **Convert token definitions**
-   - For each Jison token rule, create equivalent Chevrotain token
-   - Pay special attention to tokens that trigger state changes
-   - Preserve token precedence and ordering from Jison
-
-3. **Implement state transitions**
-   - Tokens that call `pushState` should use Chevrotain's push_mode
-   - Tokens that call `popState` should use Chevrotain's pop_mode
-   - Maintain the stack-based behavior of Jison states
-
-### Phase 3: Parser Implementation
-1. **Convert grammar rules**
-   - Translate each Jison grammar rule to Chevrotain's format
-   - Preserve the rule hierarchy and structure
-   - Maintain the same rule names where possible
-
-2. **Handle semantic actions**
-   - Convert Jison's semantic actions to Chevrotain's visitor pattern
-   - Ensure data structures remain compatible
-   - Preserve any side effects or state mutations
-
-### Phase 4: Testing Strategy
-1. **Test file naming convention**
-   - Original: `*.spec.js`
-   - Converted: `*-chev.spec.ts`
-   - Keep test files in the same directory: `src/diagrams/flowchart/parser/`
-
-2. **Test conversion approach**
-   - Copy each original test file
-   - Rename with `-chev.spec.ts` suffix
-   - Modify only the import statements and parser initialization
-   - Keep test cases and assertions unchanged
-   - Run tests individually: `vitest packages/mermaid/src/diagrams/flowchart/parser/flow-chev.spec.ts --run`
-
-3. **Validation checklist**
-   - All original test cases must pass
-   - Test coverage should match the original
-   - Performance should be comparable or better
-
-### Phase 5: Integration
-1. **API compatibility**
-   - Ensure the new parser exposes the same public interface
-   - Return values should match the original parser
-   - Error messages should be equivalent
-
-2. **Gradual migration**
-   - Create a feature flag to switch between parsers
-   - Allow parallel testing of both implementations
-   - Monitor for any behavioral differences
-
-## Common Pitfalls to Avoid
-1. **State management differences**
-   - Chevrotain's modes are more rigid than Jison's states
-   - Ensure proper mode stack behavior is maintained
-   - Test deeply nested state scenarios
-
-2. **Token precedence**
-   - Chevrotain's token ordering matters more than in Jison
-   - Longer patterns should generally come before shorter ones
-   - Test edge cases with ambiguous inputs
-
-3. **Semantic action timing**
-   - Chevrotain processes semantic actions differently
-   - Ensure actions execute at the correct parse phase
-   - Validate that data flows correctly through the parse tree
-
-## Success Criteria
-- All original tests pass with the new parser
-- No changes required to downstream code
-- Performance is equal or better
-- Parser behavior is identical for all valid inputs
-- Error handling remains consistent
-

-
-## Summary: Using Multi-Mode Lexing in Chevrotain
-
-Chevrotain supports *multi-mode lexing*, allowing you to define different sets of tokenization rules (modes) that the lexer can switch between based on context. This is essential for parsing languages with embedded or context-sensitive syntax, such as HTML or templating languages[3][2].
-
-**Key Concepts:**
-
-- **Modes:** Each mode is an array of token types (constructors) defining the valid tokens in that context.
-- **Mode Stack:** The lexer maintains a stack of modes. Only the top (current) mode's tokens are active at any time[2].
-- **Switching Modes:**
-  - Use `PUSH_MODE` on a token to switch to a new mode after matching that token.
-  - Use `POP_MODE` on a token to return to the previous mode.
-
-**Implementation Steps:**
-
-1. **Define Tokens with Mode Switching:**
-   - Tokens can specify `PUSH_MODE` or `POP_MODE` to control mode transitions.
-   ```javascript
-   const EnterLetters = createToken({ name: "EnterLetters", pattern: /LETTERS/, push_mode: "letter_mode" });
-   const ExitLetters = createToken({ name: "ExitLetters", pattern: /EXIT_LETTERS/, pop_mode: true });
-   ```
-
-2. **Create the Multi-Mode Lexer Definition:**
-   - Structure your modes as an object mapping mode names to arrays of token constructors.
-   ```javascript
-   const multiModeLexerDefinition = {
-     modes: {
-       numbers_mode: [One, Two, EnterLetters, ExitNumbers, Whitespace],
-       letter_mode: [Alpha, Beta, ExitLetters, Whitespace],
-     },
-     defaultMode: "numbers_mode"
-   };
-   ```
-
-3. **Instantiate the Lexer:**
-   - Pass the multi-mode definition to the Chevrotain `Lexer` constructor.
-   ```javascript
-   const MultiModeLexer = new Lexer(multiModeLexerDefinition);
-   ```
-
-4. **Tokenize Input:**
-   - The lexer will automatically switch modes as it encounters tokens with `PUSH_MODE` or `POP_MODE`.
-   ```javascript
-   const lexResult = MultiModeLexer.tokenize(input);
-   ```
-
-5. **Parser Integration:**
-   - When constructing the parser, provide a flat array of all token constructors used in all modes, as the parser does not natively accept the multi-mode structure[1].
-   ```javascript
-   // Flatten all tokens from all modes for the parser
-   let tokenCtors = [];
-   for (let mode in multiModeLexerDefinition.modes) {
-     tokenCtors = tokenCtors.concat(multiModeLexerDefinition.modes[mode]);
-   }
-   class MultiModeParser extends Parser {
-     constructor(tokens) {
-       super(tokens, tokenCtors);
-     }
-   }
-   ```
-
-**Best Practices:**
-
-- Place more specific tokens before more general ones to avoid prefix-matching issues[2].
-- Use the mode stack judiciously to manage nested or recursive language constructs.
-
-**References:**
-- Chevrotain documentation on [lexer modes][3]
-- Example code and integration notes from Chevrotain issues and docs[1][2]
-
-This approach enables robust, context-sensitive lexing for complex language grammars in Chevrotain.

-**Important**
-Always assume I want the exact code edit!
-Always assume I want you to apply this fixes directly!
-
-# Running tests
-
-Run tests in one file from the project root using this command:
-`vitest #filename-relative-to-project-root# --run`
-
-Example:
-`vitest packages/mermaid/src/diagrams/flowchart/parser/flow-chev.spec.ts --run`
-
-To run all flowchart test for the migration
-`vitest packages/mermaid/src/diagrams/flowchart/parser/*flow*-chev.spec.ts --run`
-
-To run a specific test in a test file:
-`vitest #filename-relative-to-project-root# -t "string-matching-test" --run`
-
-Example:
-`vitest packages/mermaid/src/diagrams/flowchart/parser/flow-chev-singlenode.spec.js -t "diamond node with html in it (SN3)" --run`
-
-# Current Status of Chevrotain Parser Migration
-
-## ✅ COMPLETED TASKS:
-- **Interaction parsing**: Successfully fixed callback functions with multiple comma-separated arguments
-- **Tooltip handling**: Fixed tooltip support for both href and callback syntax patterns
-- **Test coverage**: All 13 interaction tests passing, 24 style tests passing, 2 node data tests passing
-
-## ❌ CRITICAL ISSUES REMAINING:
-- **Edge creation completely broken**: Most tests show `edges.length` is 0 when should be non-zero
-- **Core parsing regression**: Changes to `clickStatement` parser rule affected broader parsing functionality
-- **Vertex chaining broken**: All vertex chaining tests failing due to missing edges
-- **Overall test status**: 126 failed | 524 passed | 3 skipped (653 total tests)
-
-## 🎯 IMMEDIATE NEXT TASKS:
-1. **URGENT**: Fix edge creation regression - core parsing functionality is broken
-2. Investigate why changes to interaction parsing affected edge parsing
-3. Restore edge parsing without breaking interaction functionality
-4. Run full test suite to ensure no other regressions
-
-## 📝 KEY FILES MODIFIED:
-- `packages/mermaid/src/diagrams/flowchart/parser/flowParser.ts` - Parser grammar rules
-- `packages/mermaid/src/diagrams/flowchart/parser/flowAst.ts` - AST visitor implementation
-
-## 🔧 RECENT CHANGES MADE:
-1. **Parser**: Modified `clickCall` rule to accept multiple tokens for complex arguments using `MANY()`
-2. **AST Visitor**: Updated `clickCall` method to correctly extract function names and combine argument tokens
-3. **Interaction Handling**: Fixed tooltip handling for both href and callback syntax patterns
-
-## ⚠️ REGRESSION ANALYSIS:
-The interaction parsing fix introduced a critical regression where edge creation is completely broken. This suggests that modifications to the `clickStatement` parser rule had unintended side effects on the core parsing functionality. The parser can still tokenize correctly (as evidenced by passing style tests) but fails to create edges from link statements.
-
-## 🧪 TEST COMMAND:
-Use this command to run all Chevrotain tests:
-`pnpm vitest packages/mermaid/src/diagrams/flowchart/parser/flow*chev*.spec.js --run`
