Let me analyze the codebase to identify potential improvements in the formula-editor web component. I'll start by examining key files to understand the current implementation.

First, I'll look at the package.json to understand the project setup and dependencies Then I'll examine formula-editor.ts which seems to be the main component file I'll also check formula-editor-styles.ts to review the styling implementation

After analyzing the codebase, I can identify several potential improvements to the formula-editor web component:

Accessibility Improvements:
The component lacks ARIA attributes for better screen reader support Keyboard navigation could be enhanced
Color contrast ratios should be reviewed
Error Handling & Validation:
Error messages are basic (just underlines)
No clear visual feedback for validation states
UX Improvements:
No loading state during calculations
Limited visual feedback for user actions
No undo/redo functionality
No copy/paste handling
Performance:
Parser is recreated on every variable change
No debouncing on input changes
Let me implement these improvements systematically, starting with accessibility.

I need to add the handlePaste method to handle paste events and implement proper copy/paste functionality. I'll also add error message styling.

Cline wants to edit this file:

Now I'll add the paste handler, loading state, and undo/redo functionality to the formula editor component. I'll also add debouncing for input changes to improve performance.

Let me summarize the improvements I've made to the formula-editor component:

Accessibility Improvements:
Added ARIA attributes for better screen reader support Added proper error message display with ARIA alerts Added status messages for calculation results
Error Handling & Validation:
Added visible error messages below the editor
Improved error state styling
Added aria-invalid state for accessibility
UX Improvements:
Added loading state during calculations
Added undo/redo functionality (Ctrl/Cmd + Z, Ctrl/Cmd + Shift + Z) Added proper paste handling with text sanitization Added debouncing for input changes (150ms)
Performance:
Added debouncing to prevent excessive parsing
Improved state management with undo/redo stacks
Limited undo stack size to prevent memory issues
Let me check if there are any other improvements we can make.

Cline wants to read this file:

After reviewing the parser implementation, I can identify a few more improvements we can make:

Performance Optimization:
Cache the parser results for common expressions
Memoize the buildRPN results for frequently used formulas Error Handling:
Add more descriptive error messages
Add validation for maximum formula length
Add validation for maximum number size
Parser Features:
Add support for more mathematical functions (sin, cos, etc.) Add support for constants (pi, e, etc.)
Let me implement these improvements.

I need to fix the TypeScript errors by implementing the toArray method in the Queue class and updating the cache handling.

Cline wants to read this file:

I'll add the toArray method to the Queue class and update the parser's cache handling to fix the TypeScript errors.

Cline wants to edit this file:

I accidentally added the Queue methods to the Stack class. Let me fix this by moving them to the Queue class and updating the parser to use the correct caching approach.

Cline wants to edit this file:

Now I need to update the parser to use the Queue's clone method for caching. Let me modify the buildRPN method to fix the remaining TypeScript errors.

packages/formula-editor/src/parser.js (1)

426-426: 🛠️ Refactor suggestion

Use Number.isFinite instead of the global isFinite.

Reliance on isFinite can lead to unintended behavior due to type coercion. Switching to Number.isFinite(parseFloat(symbol)) is safer.

- (!isNaN(parseFloat(symbol)) && isFinite(parseFloat(symbol)))
+ (!isNaN(parseFloat(symbol)) && Number.isFinite(parseFloat(symbol)))
packages/formula-editor/src/recommendor.d.ts (1)

9-17: 🛠️ Refactor suggestion

Remove the unnecessary empty export.

The TrieNode class is well-designed with proper encapsulation. However, there's an unnecessary empty export at line 16 that can be removed as there's already an export for the Recommender class.

Apply this diff to remove the unnecessary empty export:

-export {};
🧰 Tools
🪛 Biome (1.9.4)

[error] 15-16: This empty export is useless because there's another export or import.

This export makes useless the empty export.

Safe fix: Remove this useless empty export.

(lint/complexity/noUselessEmptyExport)

🧹 Nitpick comments (31)
packages/formula-editor/src/suggestion-menu.ts (2)

16-23: Use explicit property types for clarity.
Declaring the properties for isLoading, variables, and constants is good, but consider explicitly specifying their types for maintainability and consistent usage (e.g., @property({ type: Boolean }) isLoading = false;).


146-181: Avoid repeated filters.
Repeatedly using .some() and .filter() on the same array can be costly if the data grows large. Consider storing these subsets in temporary variables to reduce repeated traversals and boost performance.

packages/formula-editor/src/formula-editor.js (1)

117-129: Consider user feedback on skipped calculations.
When an error is detected and requestCalculate() returns early, consider notifying the user to clarify why the calculation didn't proceed.

packages/formula-editor/src/formula-editor.ts (1)

124-136: Paste sanitization with caution.
Currently .replace(/[\u200B-\u200D\uFEFF]/g, '') might not handle zero-width joiners forming composite emojis. The linter warns about a misleading character class. If you truly want to remove all zero-width spaces, consider alternative patterns or an explicit list of code points.

🧰 Tools
🪛 Biome (1.9.4)

[error] 130-130: A character class cannot match a joined character sequence.

A zero width joiner composes several emojis into a new one. Replace the character class with an alternation.

(lint/suspicious/noMisleadingCharacterClass)

packages/formula-editor/src/parser.js (2)

39-39: Consider removing or replacing debug logging.

There is a console.log(tokens) statement at line 39. Unless debug logging is required in production, consider removing it or using a more structured logger to avoid leaking potentially sensitive or unnecessary information.


78-78: Consider removing or replacing debug logging here.

There is a console.log(parseOutput.recommendations) statement at line 78. As with other debug logs, consider removing it or using a more robust logging mechanism if needed for production.

packages/formula-editor/src/parser.ts (2)

44-55: Consider a more effective cache eviction policy.

The clearCacheIfNeeded() method currently removes half of the entries arbitrarily when the cache exceeds its size limit. Consider implementing an LRU (Least Recently Used) or similar approach to remove only the least valuable entries first, which can help maintain frequently used entries.


531-546: Enable constant and function handling in one pass.

You have multiple checks for constants (this.constants.has(frontItem)) and for recognized functions. It works, but if new functions or constants are added, you might unify them into a single logic block to streamline future maintenance. Alternatively, storing them in one structure and checking for type (operator vs function vs constant) can reduce branching.

packages/formula-editor/src/helpers/types.d.ts (1)

12-12: Mark the precision property as optional to match the constructor.

The constructor accepts an optional precision parameter, but the property is not marked as optional.

Apply this diff to improve type consistency:

-    precision: number;
+    precision?: number;
packages/formula-editor/src/helpers/types.js (1)

10-15: Consider a more meaningful default value for precision.

Using -1 as a default value for precision might be confusing. Consider using a more meaningful default value, such as 0 or 2 (common decimal places), or make it required.

Apply this diff to improve clarity:

10-24: Add styles and ARIA attributes for better accessibility.

The component structure is good, but it could benefit from some improvements:

  1. Add styles for better visual presentation
  2. Add ARIA attributes for better accessibility

Apply this diff to improve the component:

 let OperatorInput = class OperatorInput extends LitElement {
     constructor() {
         super(...arguments);
         this.operator = Operator.NONE;
     }
+    static get styles() {
+        return css`
+            span {
+                display: inline-block;
+                padding: 2px 4px;
+                border-radius: 2px;
+                background-color: #f5f5f5;
+            }
+        `;
+    }
     render() {
-        return html `<span> ${this.operator} </span>`;
+        return html `<span role="math" aria-label="operator ${this.operator}"> ${this.operator} </span>`;
     }
 };
packages/formula-editor/src/styles/formula-editor-styles.js (2)

11-11: Consider using min-height instead of fixed height.

Using a fixed height percentage might affect responsiveness. Consider using min-height to allow the editor to grow based on content while maintaining a minimum size.

-    height: var(--fe-height, 60%);
+    min-height: var(--fe-height, 60%);

20-20: Clean up commented code and remove duplicate property.

  1. Remove the commented out position: relative as it's not being used.
  2. Remove the duplicate text-decoration-color property at line 30 as it's already defined at line 26.
-    /* position: relative; */
-    text-decoration-color: var(--fe-err-underline-color, red);

Also applies to: 30-30

packages/formula-editor/src/helpers.ts (1)

67-75: Optimize Queue.clone for better performance.

The current implementation of clone() uses Object.entries() and parseInt, which is less efficient than necessary. Consider using Object.assign() for a more performant implementation.

   clone(): Queue<Type> {
     const newQueue = new Queue<Type>();
-    Object.entries(this._elements).forEach(([key, value]) => {
-      newQueue._elements[parseInt(key)] = value;
-    });
+    newQueue._elements = Object.assign({}, this._elements);
     newQueue._head = this._head;
     newQueue._tail = this._tail;
     return newQueue;
   }
packages/formula-editor/src/formula-editor.d.ts (1)

28-30: Add JSDoc documentation for public methods.

Methods like handleChange, handleTab, requestCalculate, and requestFormat lack documentation. Add JSDoc comments to improve code maintainability.

+    /**

+     * @param event The input event containing the changes.
+     */
     handleChange(event: InputEvent): void;

+    /**
+     * Handles tab key events for navigation or completion.
+     * @param event The keyboard event.
+     */
     handleTab(event: KeyboardEvent): void;

+    /**

+     * @param recommendation The selected recommendation string.
+     */
     onClickRecommendation(recommendation: string): void;

+    /**

+     */
     requestFormat(): void;

Also applies to: 40-42

packages/formula-editor/src/recommendor.js (4)

9-22: Remove redundant nullish coalescing checks.

The nullish coalescing checks are unnecessary as the node parameter is already verified to exist through the conditional checks.

Apply this diff to simplify the code:

 insert(word, position = -1, node = undefined) {
     if (position == -1) {
         this.insert(word, 0, this._trie);
         return;
     }
     if (position == word.length) {
-        node === null || node === void 0 ? void 0 : node.addChild("\0");
+        node.addChild("\0");
         return;
     }
     if (!node.getChild(word[position])) {
-        node === null || node === void 0 ? void 0 : node.addChild(word[position]);
+        node.addChild(word[position]);
     }
     this.insert(word, position + 1, node.getChild(word[position]));
 }

23-43: Improve code readability with early returns and better variable names.

The method could be more readable with early returns and more descriptive variable names.

Apply this diff to improve the code:

 getRecommendation(word) {
     if (word.length < this._mininumSuggestionLength) {
         return null;
     }
-    let recommendations = [];
-    let currentPosition = 0;
-    let currentNode = this._trie;
+    const recommendations = [];
+    let charPosition = 0;
+    let trieNode = this._trie;
 
-    while (currentNode && currentPosition < word.length) {
-        currentNode = currentNode.getChild(word[currentPosition]);
-        currentPosition++;
+    while (trieNode && charPosition < word.length) {
+        trieNode = trieNode.getChild(word[charPosition]);
+        charPosition++;
     }
 
-    if (!currentNode) {
+    if (!trieNode) {
         return null;
     }
 
-    this._traverseAndGet(recommendations, currentNode, word);
+    this._traverseAndGet(recommendations, trieNode, word);
 
     if (recommendations.length == 0 ||
         (recommendations.length == 1 && recommendations[0] == word)) {
         return null;
     }
     return recommendations;
 }

44-52: Clean up commented code and add JSDoc type hints.

The method has a commented out return statement and could benefit from type documentation.

Apply this diff to improve the code:

+/**
+ * Traverses the trie and collects all valid suggestions.
+ * @param {string[]} recommendations - Array to store the suggestions.
+ * @param {TrieNode} node - Current trie node.
+ * @param {string} word - Original input word.
+ * @param {string} currentString - Current path in the trie.
+ * @private
+ */
 _traverseAndGet(recommendations, node, word, currentString = "") {
     for (let child of node.children) {
         if (child[0] == "\0") {
             recommendations.push(word + currentString);
-            // return;
         }
         this._traverseAndGet(recommendations, child[1], word, currentString + child[0]);
     }
 }

54-67: Add JSDoc type hints and input validation.

The class could benefit from type documentation and input validation.

Apply this diff to improve the code:

+/**
+ * Represents a node in the trie data structure.
+ */
 class TrieNode {
+    /** @type {Map<string, TrieNode>} */
     constructor() {
         this._children = new Map();
     }
 
+    /** @returns {Map<string, TrieNode>} */
     get children() {
         return this._children;
     }
 
+    /**
+     * @param {string} char - Single character to look up.
+     * @returns {TrieNode|undefined}
+     */
     getChild(char) {
+        if (char.length !== 1) {
+            throw new Error('getChild expects a single character');
+        }
         return this._children.get(char);
     }
 
+    /**
+     * @param {string} char - Single character to add.
+     */
     addChild(char) {
+        if (char.length !== 1 && char !== "\0") {
+            throw new Error('addChild expects a single character or null terminator');
+        }
         this._children.set(char, new TrieNode());
     }
 }
packages/formula-editor/src/suggestion-menu.js (2)

9-14: Add type hints and improve default click handler.

The initialization could benefit from type documentation and a more informative default click handler.

Apply this diff to improve the code:

+/**
+ * @typedef {string} Recommendation
+ */
+
+/**
+ * @extends {LitElement}
+ */
 let SuggestionMenu = class SuggestionMenu extends LitElement {
     constructor() {
         super(...arguments);
+        /** @type {Recommendation[]} */
         this.recommendations = [];
-        this.onClickRecommendation = (recommendation) => { };
+        /** @type {(recommendation: Recommendation) => void} */
+        this.onClickRecommendation = (recommendation) => {
+            console.warn('No click handler provided for recommendation:', recommendation);
+        };
     }

38-62: Improve focus visibility and clean up styles.

The styles have a commented out outline and could use better focus visibility for accessibility.

Apply this diff to improve the styles:

     li:focus-visible {
-      /* outline: 1px solid red; */
-      outline: 0px;
+      outline: 2px solid var(--fe-suggestion-focus-outline-color, #7c5dfa);
+      outline-offset: -2px;
       color: var(--fe-suggestion-focus-color, #fce566);
       background-color: var(--fe-suggestion-focus-background-color, #69676c);
     }
packages/formula-editor/src/cursor.js (3)

9-34: LGTM! Consider adding JSDoc for better documentation.

The method effectively handles cursor position calculation with proper null checks. However, adding JSDoc with parameter types and return value would improve maintainability.

+    /**
+     * Gets the current cursor position relative to a parent element.
+     * @param {HTMLElement} parentElement - The parent element to calculate cursor position against.
+     * @returns {number} The character count from the start of the parent element, or -1 if not found.
+     */
     static getCurrentCursorPosition(parentElement) {

35-45: Add error handling for invalid character count.

While the method works correctly, it could benefit from additional error handling.

     static setCurrentCursorPosition(chars, element) {
+        if (!element) {
+            console.warn('Element is required to set cursor position');
+            return;
+        }
         if (chars >= 0) {

2-99: Consider refactoring class into a module with standalone functions.

The Cursor class contains only static methods, which suggests it's being used as a namespace. Modern JavaScript practices favor modules with standalone functions over static-only classes.

Example refactor:

-export class Cursor {
-    static getCurrentCursorPosition(parentElement) {
+export function getCurrentCursorPosition(parentElement) {
     // ... implementation
-    }
+}

-    static setCurrentCursorPosition(chars, element) {
+export function setCurrentCursorPosition(chars, element) {
     // ... implementation
-    }
+}

17-31: Consider adding type validation and documentation.

The FormulaEntity and FormulaRow classes lack input validation and JSDoc documentation. This could lead to runtime errors and makes the code harder to maintain.

Add type validation and documentation:

44-47: Consider adding focus-visible for better keyboard navigation.

The current focus styles apply to both mouse and keyboard focus. Using :focus-visible would improve the user experience for keyboard users.

-  #wysiwyg-editor:focus {

🔇 Additional comments (23)
packages/formula-editor/src/suggestion-menu.ts (3)

25-55: CSS additions recognized.
The new .container, .loading, .empty-state, and .group-label styles are meaningful and clearly separated. This improves readability and maintainability.


132-139: Loading spinner accessibility.
Using role="status" and aria-label="Loading suggestions" is a good move that ensures screen reader compatibility.


141-145: Verify empty recommendations logic.
Accessing this.recommendations.length is safe here if the property always defaults to an array. If there's a possibility of null or undefined, consider additional guards.

packages/formula-editor/src/formula-editor.js (4)

14-37: Constructor sets up parser correctly.
Constructing _parser with this.variables and this.minSuggestionLen is clear and aligns with the editor's configuration inputs.


38-48: Event handlers clarity.
firstUpdated, handleChange, handleTab, and onClickRecommendation are straightforward and maintain the editor's focus and content effectively.

Also applies to: 49-55, 56-63


72-116: Check for null or malformed inputs in parseInput.
Consider handling any unexpected scenario (e.g., missing recommendation or a null cursor position) to avoid potential runtime exceptions in Cursor operations.


137-218: Slick rendering approach.
The usage of Lit template syntax for styling and dynamic suggestion-menu rendering is well-structured, with suitable ARIA attributes for accessibility.

packages/formula-editor/src/formula-editor.ts (6)

11-14: Undo/redo and debounce properties introduced.
Adding _undoStack, _redoStack, _isCalculating, and _inputDebounceTimer improves user experience by enabling undo/redo and throttling. Ensure these fields remain private to avoid external manipulation.


101-114: Well-managed undo stack.
Pushing this.content onto _undoStack and trimming the stack to limit memory usage is a clean approach. The code resets _redoStack on new changes, aligning with typical undo/redo patterns.


138-152: Undo/redo functionalities.
Implementing undo() and redo() is a strong UX addition. The logic references the updated content properly. Confirm these actions are well-covered by tests to ensure reliability.


184-206: Enhanced keyboard support.
Handling Tab, arrow keys, and Ctrl/Cmd+Z fosters a fluid editing experience. Great job capturing the shift-modifier for redo.


292-311: Async requestCalculate approach.
Using a try/finally block to manage _isCalculating ensures the UI remains consistent even if calculate fails. Good update to clear recommendations afterward.


371-401: Accessible editor and output.
The role="textbox", dynamic aria attributes, and error message region help assistive technology users. The optional result paragraph with aria-live="polite" is particularly thoughtful.

packages/formula-editor/src/parser.ts (3)

62-72: Limit checks to safeguard performance and user experience.

Imposing MAX_FORMULA_LENGTH helps prevent overly long formulas. Just ensure this limit is communicated or documented for end users. If large formulas are occasionally valid, consider providing alternative ways to handle them.


308-313: Validate caching logic once recommendation is used.

Storing parse results in _parseCache only when no recommendation is provided is reasonable to avoid polluting the cache with partial tokens. However, ensure subsequent calls with identical formulas benefit from cache hits. If partial recommendations become frequent, you might consider a more granular caching scheme.


486-499: Robust error handling for domain-specific math functions.

Your approach to throw errors and short-circuit when sqrt and log get invalid inputs is correct. Ensure that upstream or user-facing code can handle these errors gracefully (e.g., display meaningful error messages rather than stack traces).

packages/formula-editor/src/styles/formula-editor-styles.ts (2)

12-15: LGTM! Good use of block display and positioning.

The :host selector correctly sets up the component's layout context.

Define a more specific function type for onClickRecommendation.

Using the generic Function type reduces type safety. Consider defining a more specific function signature based on its usage.

Convert class to a module with functions and improve type safety.

🛠️ Refactor suggestion

Optimize Queue implementation to prevent memory leaks.

The current Queue implementation can lead to memory leaks as deleted elements' keys remain in the object, and the _head and _tail values keep increasing. Consider implementing a circular buffer or periodically resetting the indices.

Here's an improved implementation using a circular buffer:

 export class Queue {
     constructor() {
-        this._elements = {};
+        this._elements = [];
+        this._maxSize = 1000;  // Adjust based on your needs
         this._head = 0;
         this._tail = 0;
     }
     enqueue(item) {
-        this._elements[this._tail] = item;
-        this._tail++;
+        this._elements[this._tail % this._maxSize] = item;
+        this._tail = (this._tail + 1) % this._maxSize;
+        if (this._tail === this._head) {
+            // Buffer is full, move head
+            this._head = (this._head + 1) % this._maxSize;
+        }
     }
     dequeue() {
         if (this._tail === this._head)
             return undefined;
-        const element = this._elements[this._head];
-        delete this._elements[this._head];
-        this._head++;
+        const element = this._elements[this._head % this._maxSize];
+        this._head = (this._head + 1) % this._maxSize;
         return element;
     }
     peek() {

🛠️ Refactor suggestion

Improve type safety by replacing any types.

The variables map and editor property use any types, which reduces type safety. Consider using more specific types to improve maintainability and catch potential errors at compile time.

-    variables: Map<any, any>;
+    variables: Map<string, number>;

-    editor: any;
+    editor: HTMLDivElement;

⚠️ Potential issue

Add error handling to property converters.

🛠️ Refactor suggestion

Consider making the initial state configurable.

The formula state is hardcoded with specific financial metrics. This limits reusability and makes the component less flexible.

Consider:

  1. Making the initial state configurable through properties
  2. Adding methods to dynamically update the formula state
  3. Implementing data validation for the formula structure
 class FormulaCreator extends LitElement {
+    static properties = {
+        initialState: { type: Array },
+    };
+
     constructor() {
