Helper utility to manage local rippled mainnet and sidechain networks

Project description

Claudia

Claudia is a helper utility that simplifies setting up and managing a development environment for the XRP Ledger. It helps the user to run a local network using a built/installed instance of rippled. It can also launch a sidechain network. These networks can be later used to perform local testing and debugging.

Claudia was developed by the XRPL Automation Team as an internal tool to help with XRPL local development, debugging and testing. As the tool matured, the team quickly realized its potential and decided to expose it outside of Ripple, so that everyone can benefit from its capabilities.

Following are some of the important tasks that can be performed using Claudia:

  • Build rippled from local code.
  • Install rippled from pre-built binaries released by Ripple.
  • Manage a local-mainnet network using local rippled instance.
  • Locally build a local witness server to start a sidechain network.
  • Manage a local-sidechain network.
  • Manage rippled features on the local-mainnet and local-sidechain networks.

General Prerequisites

Claudia can be installed on both macOS and Ubuntu. Currently, there is no support for Windows. Following prerequisites must be installed before installing Claudia:

  • Python3
    • Run python3 --version to check if Python3 is already installed.
    • If Python3 is not installed, please install it using the official Python installer.
    • Verify installation by running: python3 --version
  • pip3
    • Run pip3 --version to check if Python3 is already installed.
    • If pip3 is not installed, follow the next steps:
      • macOS:
        • python3 -m ensurepip --upgrade
      • Linux:
        • sudo apt update
        • sudo apt install python3-pip
      • Verify installation by running: pip3 --version
  • docker

Installation

Once the general prerequisites have been installed, Claudia can be installed from PyPi. From your terminal please run:

pip3 install claudia

If you want to build Claudia from the local code, you can run:

  rm -fr build/ dist/ claudia.egg-info
  pip uninstall -y claudia
  python3 setup.py sdist bdist_wheel
  pip install dist/*.tar.gz
  rm -fr build/ dist/ claudia.egg-info

Usage

Claudia has a bunch of self-explanatory features. Claudia CLI offers two CLI experiences:

  1. Demo mode. This is an interactive mode that can help reduce typing efforts significantly. You would mostly navigate a pre-built menu using ↑ ↓ and ↵ keys. Minimal typing will be required.
  2. (Standard) CLI mode.

How to run Claudia CLI commands?

After installing claudia, go to your terminal and run claudia. Each command supports --help flag that displays the usage and arguments. e.g. claudia --help, claudia run --help etc.

How to run Claudia in demo mode?

From your terminal and type claudia demo.


Features

Claudia offers a bunch of features which allows you to manage local rippled instance, manage networks, run tests and even learn a few XRPL tricks. This section walks you through some major features.

How to build rippled?

Claudia offers a way to build rippled from local code. You will need to clone rippled repository first before starting with this step. If you intend to use sidechain functionality, please use this rippled fork instead.

Once the repository has been cloned, you can build rippled as follows. Each option would require you to provide the absolute path to the cloned repository.

  • CLI Mode
    • Run claudia rippled build --repo <repo_path>
  • Demo Mode
    • Select Custom XRPL Networks -> Build rippled from local code

How to install rippled?

Claudia offers a way to install rippled using the pre-built binaries distributed by Ripple. By default, Claudia will choose binaries generated from the master branch. You also have an option to from master, develop and release branches. You can install rippled as follows:

  • CLI Mode
    • Run claudia rippled install to install rippled binaries built from master branch.
    • Run claudia rippled install --rippled_branch <branch_name> and choose the rippled branch.
  • Demo Mode
    • Select Custom XRPL Networks -> Install rippled

How to switch between build and install rippled modes?

Once you build or install rippled, Claudia will remember that context. If you have already built and installed rippled in both modes, and would like to switch between the two modes, run the following:

  • CLI Mode
    • Run claudia set-install-mode build to set build mode.
    • Run claudia set-install-mode install to set install mode.
  • Demo Mode
    • Select Settings -> Set install mode as build to set build mode.
    • Select Settings -> Set install mode as install to set install mode.

Please note that all previously running networks will have to be stopped and started again after switching rippled modes.

How to enable a feature in rippled?

Please note that there is no validation for feature name. Please make sure the feature name is correct (case-sensitive). You can follow these instructions to enable a rippled feature:

  • CLI Mode
    • Run claudia enable-feature --feature <feature_name>
  • Demo Mode
    • Select Settings -> Enable a rippled feature

How to disable a feature in rippled?

Please note that there is no validation for feature name. Please make sure the feature name is correct (case-sensitive). You can follow these instructions to disable a rippled feature:

  • CLI Mode
    • Run claudia disable-feature --feature <feature_name>
  • Demo Mode
    • Select Settings -> Disable a rippled feature

How to build witness server?

Before you can start a sidechain network, you will need to build a witness server locally. You will need to clone XBridge Witness repository first before starting on this step. Once the repository has been cloned, you can build the witness server as follows. Each option would require you to provide the absolute path to the cloned repository.

  • CLI Mode
    • Run claudia witness build --repo <repo_path>
  • Demo Mode
    • Select Custom XRPL Networks -> Build witness server

How to start a local-mainnet network?

Before you can start a local mainnet network, rippled has to be built or installed locally. Afterwards, you can follow these instructions to start a local mainnet network:

  • CLI Mode
    • Run claudia local-mainnet start
  • Demo Mode
    • Select Custom XRPL Networks -> Start local-mainnet

This can take up to a minute. Once the network has been launched, you can access the network as follows:

  • WebSocket (ws): 127.0.0.1:6001
  • JSON-RPC (http): 127.0.0.1:5001

How to stop a local-mainnet network?

You can follow these instructions to stop a local mainnet network:

  • CLI Mode
    • Run claudia local-mainnet stop
  • Demo Mode
    • Select Custom XRPL Networks -> Stop local-mainnet

How to start a local-sidechain network?

Before you can start a local sidechain network:

  1. rippled has to be built/installed locally.
  2. Witness server has to be built locally.
  3. XChainBridge rippled feature has to be enabled.
  4. The local-mainnet network has to be running.

Once all the requirements have been met, you can start the local sidechain network as follows:

  • CLI Mode
    • Run claudia local-sidechain start
  • Demo Mode
    • Select Custom XRPL Networks -> Start local-sidechain

This can take up to a minute. Once the network has been launched, you can access the network as follows:

  • WebSocket (ws): 127.0.0.1:6003
  • JSON-RPC (http): 127.0.0.1:5003

How to stop a local-sidechain network?

You can follow these instructions to stop a local sidechain network:

  • CLI Mode
    • Run claudia local-sidechain stop
  • Demo Mode
    • Select Custom XRPL Networks -> Stop local-sidechain

Please note that once the sidechain has been stopped, local-mainnet has to be restarted before attempting to start the local-sidechain again.

How to clean up your computer and free resources after running Claudia?

While using claudia, there are a few files created permanently. Also, there are a few system resources which are reserved for future use. Running this command will delete these files and free up resources. As a result, any progress made by using Claudia will be lost. This action cannot be undone. Resources can be freed and your machine can be freed as follows:

  • CLI Mode
    • Run claudia clean
  • Demo Mode
    • Select Settings -> Clean up the host and free resources

How to uninstall Claudia?

We recommend that you clean up your machine before uninstalling Claudia. Afterwards, please run:

pip3 uninstall claudia
