ndnc 0.0.5

A DSL interpreter for transparent distributed execution over NDN

ndnc

A DSL interpreter for transparent distributed execution over NDN (Named Data Networking).

Write code without thinking about where it runs — local or remote. The system handles it.

Installation

pip install ndnc

Usage

Run a .ndn script

ndnc run path/to/script.ndn

Run with arguments

ndnc run path/to/script.ndn arg0 arg1

Start NDN server (producer)

ndnc serve

Examples

Fetch data by NDN name and print it:

let height = interest "/height/Mt.Fuji/"
print height

Fetch data and convert units with a local function:

let height_m = interest "/height/Mt.Fuji/"
let height_ft = m_to_feet(height_m)
print height_ft

These examples use locally registered data and run without NFD. When NFD and NLSR are running, interest first checks local data, and if not found, fetches it over the NDN network transparently.

Requirements

• Python 3.10+
• python-ndn

NDN Network Requirements

To fetch data or execute functions over an actual NDN network, the following must be running on your machine:

• NFD (NDN Forwarding Daemon) — handles NDN packet forwarding
• NLSR (Named-data Link State Routing) — manages routing between NDN nodes

Without these, interest expressions will fall back to local data only.
