Building the source

For prerequisites and detailed build instructions please read the Installation Instructions on the wiki.

Building gexp requires both a Go and a C compiler. You can install them using your favourite package manager. Once the dependencies are installed, run

make gexp

Executables

Go Expanse comes with several wrappers/executables found in the cmd directory:

• gexp Expanse CLI (expanse command line interface client)
• bootnode runs a bootstrap node for the Discovery Protocol
• exptest test tool which runs with the tests suite: /path/to/test.json > exptest --test BlockTests --stdin.
• evm is a generic Expanse Virtual Machine: evm -code 60ff60ff -gas 10000 -price 0 -dump. See -h for a detailed description.
• disasm disassembles EVM code: echo "6001" | disasm
• rlpdump prints RLP structures

Contribution

gexp can be configured via command line options, environment variables and config files.

If you'd like to contribute to go-expanse, please fork, fix, commit and send a pull request for the maintainers to review and merge into the main code base. If you wish to submit more complex changes though, please check up with the core devs first on our gitter channel to ensure those changes are in line with the general philosophy of the project and/or get some early feedback which can make both your efforts much lighter as well as our review and merge procedures quick and simple.

Please make sure your contributions adhere to our coding guidlines:

• Code must adhere to the official Go formatting guidelines (i.e. uses gofmt).
• Code must be documented adherign to the official Go commentary guidelines.
• Pull requests need to be based on and opened against the develop branch.
• Commit messages should be prefixed with the package(s) they modify.
  • E.g. "exp, rpc: make trace configs optional"

Please see the Developers' Guide for more details on configuring your environment, managing project dependencies and testing procedures.
