Subject: [PATCH 01/17] feat: Enhance completions for user-defined constructs

I've implemented comprehensive inline completion and signature help for your user-defined functions, User-Defined Types (UDTs), and enums.

Key enhancements include:

1.  **User-Defined Functions:**
    *   Accurate parsing of function names, parameters (including types and default values), docstrings (`@function`, `@param`), and export/method keywords.
    *   Correct suggestion of your function names.
    *   Detailed signature help for your functions, displaying parameters, types, defaults, and descriptions from `@param` tags.
    *   Argument completion for your function parameters, including type-appropriate variable suggestions.

2.  **User-Defined Types (UDTs):**
    *   Reliable parsing of UDT names, fields (name, type, default value, `const` status), docstrings (`@type`, `@field`), and export keywords.
    *   Completion suggestion for your UDT names.
    *   Suggestion of `.new()` constructor for UDTs.
    *   Detailed signature help for UDT constructors, showing all fields, their types, default values, and descriptions from `@field` tags.
    *   Argument completion for UDT constructor fields.
    *   Instance field completion: When typing `myUdtInstance.`, fields of `myUdtInstance` are suggested with their types, documentation, and default values.

3.  **Enums:**
    *   Your user-defined enums (conventionally UDTs with `const` fields) are supported.
    *   Enum member names are suggested with an `EnumMember` kind when accessing them (e.g., `MyEnum.MEMBER_A`).
    *   Built-in constant namespaces (e.g., `color.`) also provide `EnumMember` completions.
    *   Documentation for enum members shows their values.

These changes significantly improve your development experience by providing more intelligent and context-aware assistance when working with user-defined code structures in Pine Script.

Subject: [PATCH 03/17] fix: Refine UDT constructor inline argument suggestions

This commit addresses your feedback regarding inline completions for User-Defined Type (UDT) constructors. Specifically, it ensures that field names (e.g., `fieldname =`) are properly suggested inline and that value suggestions are contextually appropriate.

Enhancements:
- Modified `PineInlineCompletionContext.argumentInlineCompletions` to more intelligently select and prioritize inline suggestions:
    - Suggests the next available field name (e.g., `fieldname=`) when the argument slot is empty or after a comma.
    - Offers relevant value suggestions (including type-matched variables and newly added generic literals like `""`, `0`, `na`, `true`, `false`) after a field name and `=` are typed.
- Improved `PineInlineCompletionContext.createInlineCompletionItem` to correctly calculate `insertText` and `Range` for a smoother inline completion experience.
- Refined `PineCompletionProvider.argumentCompletions` to ensure consistent `CompletionItemKind` for UDT field parameters.
- Verified that `PineSignatureHelpProvider` correctly populates `PineSharedCompletionState` to support these refined UDT constructor argument suggestions.
- Removed premature clearing of completion state in `PineInlineCompletionContext` to allow you to trigger standard completions if an inline suggestion is ignored.

These changes result in a more intuitive and complete suggestion experience when working with UDT constructors, aligning with the behavior of built-in function calls.

Subject: [PATCH 05/17] feat: Enhance Docstring, Typify, and Context Menus

This commit introduces several improvements to the Pine Script VS Code extension:

1.  **Context Menu Refactoring:**
    - Simplified the editor context menu contributions in `package.json`.
    - Removed nested submenus for Pine Script commands, directly adding them to the `editor/context` group for a cleaner user experience.
    - Ensured commands like "Typify Variables" and "Generate Docstring" correctly use `when` clauses for visibility.

2.  **"Generate Docstring" Feature Enhancements:**
    - Added support for generating docstrings for `enum` declarations.
    - Updated the output format for both `type` (UDT) and `enum` docstrings based on your feedback, including `@type`, `@field`, and `@enum` tags with detailed type information and default values where applicable.

3.  **"Typify Variables" Feature Improvements:**
    - Significantly refactored the type inference logic in `PineTypify.ts`.
    - Variables can now have their types inferred from their assignment values, including:
        - String literals (including `str.format()`).
        - Number literals (int, float, scientific notation).
        - Color literals and functions (hex, `color.rgb()`, `color.new()`, named colors).
        - Boolean literals (`true`, `false`).
        - The `na` value.
        - Ternary expressions, including those involving `na`.
    - Improved reliability by checking for already-typed variables to prevent incorrect re-typing.
    - Enhanced `makeMap` to include built-in constants (`true`, `false`, `na`, common colors) for better type resolution.

4.  **Architectural Exploration (Preliminary):**
    - Investigated refactoring `VSCode.ts` and `PineClass.ts` to reduce custom abstractions and align more closely with native VS Code APIs, paving the way for future developments like a robust linter/formatter.

These changes address your feedback to improve the usability and functionality of core editing assistance features.

Subject: [PATCH 08/17] Refactor: Consolidate listeners and integrate
 CompletionService

This commit addresses several issues:

1.  Removes a large block of commented-out code in `src/PineInlineCompletionContext.ts` to improve maintainability.
2.  Integrates `PineCompletionService.ts` into `PineCompletionProvider.ts` and `PineSignatureHelpProvider.ts`. These providers now use the service for fetching completion and signature help documentation, centralizing the logic.
3.  Consolidates duplicate `onDidChangeTextDocument` listeners in `extension.ts`. This prevents `PineLint.handleDocumentChange` from being triggered twice on document changes, ensuring linting occurs only once per relevant change.

The integration of `PineCompletionService` in the providers primarily affects how they retrieve documentation for functions, methods, and UDTs. The core logic for argument completion suggestions within `PineSignatureHelpProvider` (specifically the `sendCompletions` and `extractCompletions` methods) and its usage by `PineCompletionProvider` remains largely unchanged in this refactoring pass to minimize risk, but the foundation for future improvements is now in place.

Subject: [PATCH 09/17] Refactor: Further cleanup and shared CompletionService

This commit builds upon the previous refactoring by:

1.  Removing Obsolete Code:
    - Deleted commented-out methods (`determineFunctionType`, `extractMethodString`) in `PineSignatureHelpProvider.ts`.
    - Removed unused imports in `PineInlineCompletionContext.ts`.

2.  Improving Type Safety:
    - Updated `PineCompletionProvider.ts` to use the `CompletionDoc` interface for parameters and variables handling data from `PineCompletionService`, enhancing type safety in `createCompletionItem`.

3.  Implementing Shared `PineCompletionService` Singleton:
    - Instantiated `PineCompletionService` as a singleton (`Class.pineCompletionService`) in `extension.ts`.
    - Modified `PineCompletionProvider.ts` and `PineSignatureHelpProvider.ts` to use this shared instance instead of creating their own, reducing redundancy and ensuring consistent state.
    - Added the `pineCompletionService` static member to `PineClass.ts`.

These changes further improve code maintainability, type safety, and resource management within the extension.

Subject: [PATCH 10/17] feat: Improve error and warning visibility

This commit introduces enhanced visibility for errors and warnings within the Pine Script editor by:

- Highlighting the background of lines containing errors or warnings.
- Adding distinct gutter icons for error and warning lines.

These changes are themeable through new color contributions in `package.json`:
- `pine.errorBackground`
- `pine.warningBackground`
- `pine.errorGutterIcon` (for future use, icons currently use SVG-defined colors)
- `pine.warningGutterIcon` (for future use, icons currently use SVG-defined colors)

The implementation involves:
- Defining new `TextEditorDecorationType`s in `src/extension.ts` for errors and warnings.
- Updating `src/PineLint.ts` to apply these decorations based on diagnostic severity.
- Adding new SVG icons for the gutter indicators.
