genv

README

genv is a Go imitation of Python's venv module

Why?

Go programmers typically put all their code into one workspace. Over time, it gets really difficult to keep track of dependencies and build artifacts (at least, this is the case for me). In Python development, we keep python versions and dependencies in one workspace per project. This helps isolate the dependencies for that project. Go has the additional headache of cleaning up old binaries. This project is meant to create a new workspace for each project.

How to use it

To create a development environment

$ go install github.com/nishakm/genv@latest
$ genv test
$ cd test
$ source bin/activate

To undo the dev environment

$ deactivate

To remove the dev environment

$ sudo rm -rf test

(note: root permissions are required as go sets all the file permissions to read only)

Controlling go versions

You can create dev environments for specific go versions. If the version doesn't exist in your dev environment, genv will download it for you.

$ genv -version go1.14.4 test
$ cd test
$ source bin/activate
(test)$ go version
go version go1.14.4 linux/amd64

Cloning a Go project

If you want to seed the dev environment with a specific Go project, you can do the following:

$ genv -project git@github.com/nishakm/genv test
$ cd test
$ source bin/activate
(test)$ cd gopath/src/github.com/nishakm/genv

Currently GitHub cloning via SSH and HTTPS are supported.
