Inline Parameters Extended for VSCode

Now with Golang and Python support!

This extension implements the new Inlay Hints API to add Inline Parameters for Golang, Java, Lua, PHP, and Python.

This is a feature that was popularized by JetBrains' IDEs that can give you additional context when reading your code, making it easier to understand what different function parameters refer to by showing the parameter's name inline.

Speed up your development with parameter hints!

Language Support

Currently, this extension supports the following languages:

• Golang
• Java
• Lua (with Sumneko's Lua language server)
• PHP (with the Intelephense language server)
• Python

Inlay Hint Settings

This extension utilizes the Inlay-Hints API provided by VSCode. Here are some additional settings provided by VSCode.

Name	Description	Default
editor.inlayHints.enabled	Enables Inlay Hints for the editor.	true
editor.inlayHints.fontFamily	Controls font family of inlay hints in the editor. When set to empty, the #editor.fontFamily# is used.	""
editor.inlayHints.fontSize	Controls font size of inlay hints in the editor. A default of 90% of #editor.fontSize# is used when the configured value is less than 5 or greater than the editor font size.	0

There are also several settings to enable Inlay Hints for both JavaScript and TypeScript. These settings are available in the following setting sections.

javascript.inlayHints typescript.inlayHints

Contributions

Additional language support is welcome as pull requests, and highly encouraged. You can see the source code to see how existing languages have been implemented.

Currently, the extension has 2 major steps that all language drivers must implement:

1. Parsing the source code of the currently active file (Using an AST library - AST Explorer can assist in navigating it) to retrieve a list of positions where annotations should be inserted.
2. Getting the name of the parameters to use as the annotations. Existing language drivers do this by triggering the hover providers for the function being called, and extracting the parameter names from the description.
