Overview

rodent

Build Status

rodent is a shell (bash) application which:

  • Manages multiple versions of Go.
  • Allows you to test/build your projects against multiple Go releases at ease.
  • Allows cross-compile builds for different platform targets (cgo/stdlib workaround).
  • Manages/tracks librairies dependencies by expanding the GOPATH
  • Create separate workflows within a project per environment (i.e: build projectA with ENV="PRD" on go1.2.2 and ENV="DEV" on go1.3beta2)

This is achieved without getting in your way or hijacking your shell executables/builtins by making use of shims.

In a nutshell

Install

git clone http://github.com/alouche/rodent.git /my/path/to/rodent

# Add in your .bashrc, profile etc.

[[ -s "/my/path/to/rodent" ]] && source "/my/path/to/rodent"

# Restart your existing shell or open an new one and you are set. Type "rodent".

Highlight Features

  • Define a specific go version per project source/directory
echo "gover=go1.2.2" >> .rodentrc

# Build your project
go build

# Want to switch between multiple go versions in the same project (for testing new builds)
echo "gover_ATAG=go1.3beta2" >> .rodentrc

# Export your tag as variable
export RODENT_ENV=ATAG

# Build your project
go build

Any rodent variables when suffixed with "_" are scopped as variables for the defined enviroment scope ; variables without these suffixes are used as default variables

  • Keep track of your project third party libraries
echo "godeps=/my/project/workspace" >> .rodentrc

# A dependency target per environment? easy...
echo "godeps_production=./local/prd/path" >> .rodentrc
echo "godeps_development=./local/dev/path" >> .rodentrc
  
# Fetch your dependencies
export RODENT_ENV=production
go get

# Alternatively
export RODENT_ENV=experimental
go build

You get the idea... for more information, please refer to the rodentrc guide.

Update rodent

rodent system -u

Cross-compilation

Please refer to cross-compilation environment

Why this project?

  • I wanted something light/small which allowed all the above while being transparent and out of the way.
  • Managing and tracking my third party libraries by maintaining a separate directory per project which I could simply "tar; cp and or even git submodule.."
  • I prefer using a custom GOPATH per project (or sometimes have a unique GOPATH for a subset of projects) and wanted to keep the "standard go workflow way of things" while maintaining that flexiblity/option.
  • This is an experiment.

Disclaimer

This project is relatively new and not perfect. It still requires a lot of work and does not pretend to be better than the numerous awesome tools the Golang community has created. It is just one way of tackling "Go version and dependency management", if you like it, use it and feel free to contribute.

Contributing

rodent is not locked to a specific way of doing things, so if you have or found a better way to do things or tackle some of the challenges listed here, then I would love to hear of it, so "Go" forth - fork, patch, submit and inspire. The only dependency is that rodent should remain non-intrusive to the user's workflow and relatively light.

  • Feed RODENT_GO_RELEASES with git tags fetch

    Feed RODENT_GO_RELEASES with git tags fetch

    Versions are tracked in "RODENT_GO_RELEASES" under share/releases since previously Go releases were split across legacy and new download pages. Although Rodent allows installing a non-referenced release with the "-f" option, since the move to Git, we can now re-use git tags to automatically feed versions into RODENT_GO_RELEASES so that user may directly see the latest releases prio to share/releases being updated.

    Current, releases are referenced in RODENT_GO_RELEASES under share/releases. Installation should be allowed to continue if user believes the release is available upstream but not yet referenced in RODENT_GO_RELEASES.
