HolyC for VS Code

HolyC language support for Visual Studio Code, including:

• Syntax highlighting for HolyC (.HC)
• A file icon theme forked from VS Code’s built-in Seti icon set — including a HolyC icon

---

Features

HolyC syntax highlighting

• TextMate-based highlighting for HolyC source files.
• Automatic language association for *.HC files (or select HolyC manually from the language mode picker).

HolyC file icon theme (Seti fork)

• A lightweight icon theme based on the familiar Seti look.
• Adds icons so HolyC files get their own dedicated icon.

---

Installation

From GitHub releases

• Install the most current .vsix from the GitHub releases page

• In VS-Code, right click on the .vsix file and click Install Extension VSIX

From source (local development)

git clone https://github.com/LueWasHere/holyc-vscode
cd holyc-vscode
npm install

Then press F5 in VS Code to launch an Extension Development Host window.

Usage

Syntax highlighting

• Open any *.HC file — it should automatically highlight as HolyC.

• If it doesn’t:

  1. Click the language mode in the bottom-right of VS Code (it might say something like Plain Text)

  2. Select HolyC

---

Enable the HolyC icon theme

1. Open the Command Palette:

   • Windows/Linux: Ctrl+Shift+P

   • macOS: Cmd+Shift+P

2. Type File Icon Theme

3. Choose the HolyC icon theme from the list

| After enabling the icon theme, HolyC files (like *.HC) should display the HolyC-specific icon in the Explorer.

What files are supported?

• *.HC/hc — HolyC source files
• *.H/h — HolyC source files (variation)
• *.HH/hh — HolyC header/interface files
• *.DD/dd — HolyC data definition files

(If you use additional HolyC-related extensions and want them icon’d/highlighted too, feel free to open an issue or PR.)
