Official Pomsky support for VS Code

pomsky-vscode

The official extension for the Pomsky regular expression language. It is still in development and lacks some features.

Features

• Syntax highlighting
• Underlined errors and warnings
• Auto-completion of variables and character classes
• Running tests (enable with the pomsky.runTests) configuration
• Live preview of compiled expression
  • Right-click and select Open compiled RegExp on the right or click the icon in the top right corner
• Hover tooltips for keywords and built-ins
• Embedded syntax highlighting in Markdown code blocks

Missing IDE features:

• Go to definition / find usages / rename variable
• Code formatting
• Extend selection
• Quick fixes
• Compiled Regex: find and replace

Requirements

You need to have the pomsky executable installed locally. Get it from the Releases page. Then you need to either

• go to the settings, search for pomsky.exePath and enter the path to the executable, or

• rename the executable to pomsky and move it to /usr/bin or ~/.cargo/bin so it can be detected automatically

In the future we'll add a setting to specify a path to the executable. We might also embed an executable compiled to WASM, so no setup is needed.

Extension Settings

The following configurations are available:

• pomsky.defaultFlavor: Specifies the default regex flavor

• pomsky.runTests: Enable to conveniently run tests and see test failures on every change

• pomsky.executable.path: Points to the Pomsky executable

• pomsky.executable.extraArgs: Additional arguments to pass to pomsky. For example, setting it to -Wcompat=0 disables compatibility warnings.

Issues

This extension is an alpha stage, so expect some bugs. Please report any problems you encounter here!

pomsky-vscode's Issues

Diagnostics aren't removed when the file is deleted

Steps to reproduce:

• create a .pom file with an error
• commit the file
• switch to a branch where the file doesn't exist

Problem: The folder that previously contained the file is still highlighted in red, and the "errors" panel still contains the error from the deleted file

Completions only work when file is saved with a `.pom` or `.pomsky` file extension

Distribute extension with latest WASM compiler

This will allow users to use the extension without installing the CLI locally.

Parse AST to allow renaming variables, go to definition, find usages, etc.

Update Unicode properties following Pomsky 0.10

Syntax highlighting: Allow spaces in `U+F`, don't support `U_F`

Pass content via stdin

There are platform dependent limits on how much text you can pass to a program via CLI arguments. Longer text should therefore be passed via stdin.
