Notes

This extension is not published yet. To install proceed to local install section.

Local install

# First, make sure you have Node.js version 14 or greater installed. 

# Clone the extension.
git clone https://github.com/janet-lang/vscode-janet.git
cd vscode-janet

# Install vscode-janet dependencies.
npm install

# Generate the vscode extension (VSIX) file using vsce. 
npx vsce package

# Install the extension.
code --install-extension vscode-janet-0.0.2.vsix

# Finally reload the vscode window (cmd + shift + P > Developer: Reload Window).

Alternatively you can clone the extension right into vscode's extention directory. This is easier, but can be unreliable as vscode will sometimes clean up the extension directory and remove vscode-janet.

# Clone the extension.
cd ~/.vscode/extensions
git clone https://github.com/janet-lang/vscode-janet.git

# Force vscode to regenerate the extensions.json file.
mv extensions.json /tmp/ 

# Finally reload the vscode window (cmd + shift + P > Developer: Reload Window).

# If you're finding that vscode isn't loading the extension, you can force it to
# regenerate the extensions.json file by removing ~/.vscode/extensions/extensions.json.
