Walkthrough

The changes involve significant refactoring in the StackMachineCodeGenerator class, focusing on the handling of constants and method definitions. Key modifications include renaming methods, removing the ConstDefinition struct, and updating logic to streamline constant creation and retrieval. The changes enhance the management of constants and method parameters, aligning the code with new practices for improved clarity and efficiency.

Changes

File Change Summary
src/ScriptEngine/Compiler/StackMachineCodeGenerator.cs Renamed CreateConstDefinition to CreateConstValue, updated GetConstNumber parameters, and modified constant handling in various methods.
src/ScriptEngine/Machine/Core.cs Removed the ConstDefinition struct, eliminating its associated fields and methods.

Poem

In the code where constants play,
A rabbit hops and clears the way.
With values bright and methods new,
The stack machine's dance is true.
Let's celebrate this code so fine,
For clarity and joy, we intertwine! 🐇✨

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

262-264: Update: Replacing ConstDefinition with BslPrimitiveValue in default parameter handling

The code now uses CreateConstValue and GetConstNumber(BslPrimitiveValue) instead of ConstDefinition, streamlining the process of handling default parameter values and enhancing code clarity.


Line range hint 684-688: Update: Simplifying method resolution with updated constant handling

By using GetConstNumber(DataType.String, name.GetIdentifier()), the method resolution process is streamlined, aligning with the revised constant management approach and improving maintainability.


694-696: Update: Enhanced property resolution using consistent constant retrieval

The change to utilize GetConstNumber(DataType.String, identifier) in property resolution ensures consistency in how constants are handled throughout the codebase.


Line range hint 977-984: Refactor: Consistent constant handling in object creation

In the MakeNewObjectStatic method, using GetConstNumber(DataType.String, node.TypeNameNode.GetIdentifier()) ensures that type names are handled consistently as constants, enhancing code uniformity.


1091-1094: Update: Streamlining constant processing in VisitConstant

The method now leverages CreateConstValue and GetConstNumber(BslPrimitiveValue) to process constants, eliminating the need for ConstDefinition and simplifying the constant handling mechanism.


Line range hint 1121-1130: Enhancement: Improved annotation parameter handling

By creating a BslPrimitiveValue for annotation parameters and retrieving its constant index, the code enhances consistency and clarity in annotation processing.


1149-1162: Addition: Implementing CreateConstValue for unified constant creation

The new CreateConstValue method effectively maps LexemType to DataType and parses lexem content to generate a BslPrimitiveValue, promoting code reuse and simplification.


1165-1170: Enhancement: Overloaded GetConstNumber method for flexibility

Adding an overloaded GetConstNumber(DataType type, string presentation) method allows for direct constant retrieval using data type and presentation string, increasing the flexibility of constant management.


1172-1180: Optimization: Efficient constant storage in GetConstNumber

The GetConstNumber(BslPrimitiveValue value) method now checks for existing constants before adding new ones, preventing duplicates and optimizing memory usage.

⚠️ Potential issue

Issue: Hardcoded string "Неопределено" may cause localization concerns

Using the Russian string "Неопределено" for the undefined value might lead to localization issues if the codebase needs to support multiple languages.

Consider using a language-neutral representation or retrieving the appropriate localized string to ensure better internationalization support.

  • кролик прав насчет локализации
  • presentation для Неопределено = "" (пустая строка)
  • нужно ли хранить для констант presentation, или будет достаточно ToString?
  • IMHO давно бы стоило добавить в ВМ опкоды PushUndef, PushTrue/False, да и PushInt можно

@Mr-Rm, спасибо за ваш комментарий. Вы правы, для значения 'Неопределено' поле presentation должно быть пустой строкой (""). Это поможет избежать проблем с локализацией.

Относительно необходимости хранения presentation для констант: если метод ToString() может предоставить необходимое представление значения, возможно, хранение отдельного поля presentation не требуется. Это упростит код и снизит использование памяти.

Идея добавить опкоды PushUndef, PushTrue/False и PushInt в виртуальную машину звучит отлично. Это может повысить производительность и оптимизировать работу кода.

Learning: Если метод `ToString()` обеспечивает достаточное представление константы, возможно, хранение поля `presentation` не требуется.
