lnd-dev

Generate a random development environment for lnd with established funding of channels

Motivation

Inspired by lnet, this is a development tool that creates random nodes, connects them, funds channels, and provides a UI for managing. You can begin development once launched without a complex procedure to get you started

Features

• terminal based UI
• input amount of nodes and connections per node
• easily switch between nodes in UI
• UI includes bitcoin node
• all nodes properly shutdown on exit
• generate random invoices and payments between nodes

Requirements

• bitcoind
• lnd

Usage

1. Enter number of nodes
2. Enter maximum outbound channels
3. Enter number of random payments to generate
   • these will be running in the background
   • set to zero or leave blank if no activity desired
4. Once launched, enter commands, switch nodes etc.
   • the up and down arrows will scroll previous commands from the prompt
   • switch panes and nodes per shortcuts below

Shortcuts

command	action
Ctrl-N	Opens node selection dropdown
Ctrl-I	Move to command prompt
Ctrl-O	Move to output pane
Ctrl-L	Clear output pane while in it
Ctrl-A	Copy current output buffer
Ctrl-V	From prompt, paste copied text. This is a hack for text copied with mouse from output pane

UI Anomalies

• UI component copies wrapped lines with \n so standard Ctrl-Shift-V does not work with wrapped lines. Use Ctrl-V instead
• Does not do interactive prompts so for example use -f or --force options with payinvoice or sendpayment, may be others?

TODO:

• change fmt.Sprintfs to path.Join for windows
