ariana v0.2.9

Ariana is an IDE extension and CLI tool to understand what your JS, TS and Python code does when it runs in development way faster than with a traditional debugger or with print() or console.log().

✨ Key Features

Just by running your code with the ariana CLI and by using the Ariana VSCode extension, you can:

• 🕵️ Inspect the last values taken by any expression in your code just by hovering it.
• ⏱️ See how long it took for any expression in your code to run.
• 🧵 Feed traces to Copilot/Cursor via MCP so they can know everything that happened when your code ran. (soon)

📖 How to use

1) 💾 Install the ariana CLI

With npm:

npm install -g ariana

With pip:

pip install ariana

2) ✨ Run supported code as you would from the command line but with the ariana command along side it

ariana <run command>

For example, on a JS/TS codebase it could be:

ariana npm run dev

... and on a Python codebase it could be:

ariana python myscript.py --some-options-maybe

3) 👾 In your IDE, get instant debugging information in your code files.

You can install the extension on the VSCode Marketplace, or by searching for Ariana in the extensions tab in VSCode or Cursor.

• Open a code file, press ctrl + shift + p and search for the Ariana: Toggle Traced Expressions Highlighting command.
• 🗺️ Know which code segments got ran and which didn't
• 🕵️ Inspect the values that were taken by any expression in your code

Optional: If you just want to try out Ariana on example piece of code before using it on your own code, you can do this:

git clone https://github.com/dedale-dev/node-hello.git
cd node-hello
npm i
ariana npm run start
