🌱 Blockchain Commons seedtool-cli

macos linux linter

Introduction

seedtool is a command-line tool for creating and transforming cryptographic seeds of the sort commonly used by blockchain applications.

It exercises the various cryptographic C libraries created by Blockchain Commons, as described in the Dependencies section.

Status - Feature-Complete Beta

Seedtool is now considered feature-complete and is entering beta-level testing.

Dependencies

Seedtool exercises the following Blockchain Commons libraries:

It also requires the following additional programs:

Tool Dependencies

To build seedtool you'll need to use the following tools:

  • autotools - Gnu Build System from Free Software Foundation (intro).

Recommended Installation instructions

The dependencies will be automatically installed as submodules when you run the build script. This is the recommended way to install.

Build with Docker

Install docker and run:

# Build the image
$ docker build -t seedtool-cli .
# Run the container
$ docker run --rm -it seedtool-cli --help

Build on MacOS

$ brew install autoconf automake libtool

You must then download or clone this repo. Afterward, cd into the repo directory and:

$ ./build.sh
$ sudo make install

Build on Linux

Make sure you have llvm/clang, libc++ and libc++abi installed, all with a minimum recommended version 10.

Build on Ubuntu and Debian

$ sudo apt install build-essential

$ wget https://apt.llvm.org/llvm.sh
$ chmod +x llvm.sh
$ sudo apt install lsb-release wget software-properties-common
$ sudo ./llvm.sh 10  # version 10

$ sudo apt-get install libc++-10-dev libc++abi-10-dev
$ sudo apt-get install git
$ git clone https://github.com/BlockchainCommons/seedtool-cli.git
$ cd seedtool-cli/
$ export CC="clang-10" && export CXX="clang++-10" && ./build.sh
$ sudo make install

Build on Windows

See instructions here.

Alternative Installation Instructions

The following sequence does not install the dependencies from submodules; instead they must be installed in the usual places on the build system, otherwise the ./configure step below will fail.

$ ./configure
$ make
$ sudo make install

Note: On Linux the first step is ./configure CC=clang-10 CXX=clang++-10

Incremental Build Instructions

If you wish to make changes to the source code and rebuild:

# Make source changes
$ source set_build_paths.sh # sets shell variables used by make
$ make clean # If you want a clean build
$ make

Usage Instructions

See usage examples for examples of using seedtool.

Full Documentation

See MANUAL.md for details, many more examples, and version history.

Notes for Maintainers

Before accepting a PR that can affect build or unit tests, make sure the following sequence of commands succeeds:

$ ./build.sh
$ make lint
$ make check
$ make distclean

make lint uses Cppcheck to perform static analysis on the code. All PRs should pass with no warnings.
