Development Guide

This document is intended to be the canonical source of truth for things like supported toolchain versions for building Pack. If you find a requirement that this doc does not capture, please submit an issue on github.

This document is intended to be relative to the branch in which it is found. It is guaranteed that requirements will change over time for the development branch, but release branches of Pharmer should not change.

Build Pack

Some of the Pharmer development helper scripts rely on a fairly up-to-date GNU tools environment, so most recent Linux distros should work just fine out-of-the-box.

Setup GO

Pharmer is written in Google’s GO programming language. Currently, Pharmer is developed and tested on go 1.12.5. If you haven’t set up a GO development environment, please follow these instructions to install GO.

Download Source

Using go get

$ go get -u github.com/pharmer/pharmer
$ cd $(go env GOPATH)/src/github.com/pharmer/pharmer

Using git

$ git clone git@github.com:pharmer/pharmer.git $(go env GOPATH)/src/github.com/pharmer/pharmer
$ cd $(go env GOPATH)/src/github.com/pharmer/pharmer

Install Dev tools

You need to have docker and GNU-make installed

Build Binary

$ make build
$ ./bin/linux_amd64/pharmer version

Dependency management

Pharmer uses go modules to manage dependencies. Dependencies are already checked in the vendor folder. If you want to update/add dependencies, run:

$ go mod tidy
$ go mod vendor
