Pseudocode Syntax Highlighting for VS Code

This extension provides syntax highlighting for the pseudocode language as described by "Starting Out with Programming Logic and Design" Sixth Edition by Tony Gaddis, for Visual Studio Code.

Designed for readability and clarity, this language is perfect for students, educators, and algorithm design.

• Data types: Highlights built-in types like Integer, String, Real, and Boolean.
• Function declarations and calls:
  • Example: Function Integer calculateSum(a, b)
  • Example: Call calculateSum(5, 10)
• Control structures: If, Else, Select Case, For, For Each, Do, While, End statements.
• Variable declaration and assignment:
  • Declare Integer count
  • Set count = 10
• Constants:
  • Example: Constant Integer MAX_VALUE = 100

Installation Instructions

Though this extension is not published to the Visual Studio Code Marketplace, you can still install and use it locally by following these steps:

1. Package this extension

Open this repository in VS Code and run the following vsce command package the extension:

vsce package

This will generate a .vsix file that will look something like this: pseudocode-1.0.0.vsix

2. Install the .vsix File to VS Code

Now that we've generated the .vsix file, we will now need to run a command to install the extension locally. There are two ways to do this:

1. Run a command with that file name:

code --install-extension pseudocode-1.0.0.vsix

2. Open VS Code's Command Palette and type Install from VSIXand select the .vsix file you just generated.

3. Start pseudocoding by creating a file with the extension .psc
