Getting Started With Jac and Jaseci

Installation#

Firstly make sure that Python 3.12 or higher is installed in your environment, then simply install Jac using pip:

python -m pip install -U jaclang jac-client

Tip: For enhanced terminal output with colors, panels, and spinners, optionally install jac-super:

pip install jac-super

This plugin automatically enhances all Jac CLI command output with Rich formatting.

Once you've got Jaclang installed, just give the Jac CLI a try to make sure everything's up and running smoothly.

  • Start the Jac CLI:

    jac --version

  • Run a .jac file

    jac run <file_name>.jac

  • To test run a 'Hello World' Program

    echo "with entry { print('Hello world'); }" > test.jac;
jac run test.jac;
rm test.jac;

Note

If these commands prints Hello world you are good to go.

Installing the VS Code Extension#

In addition to setting up JacLang itself, you may also want to take advantage of the JacLang language extension for Visual Studio Code (VSCode) or Cursor. This will give you enhanced code highlighting, autocomplete, and other useful language features within your editor environment.

For VS Code users:

For Cursor users:

  1. Go to the latest Jaseci release page
  2. Download the latest jaclang-extension-*.vsix file from the release assets
  3. Open Cursor
  4. Press Ctrl+Shift+P (or Cmd+Shift+P on Mac)
  5. Type >install from vsix and select the command
  6. Select the downloaded VSIX file
  7. The extension will be installed and ready to use
