Full Description








Goby is an object-oriented interpreter language deeply inspired by Ruby as well as its core implementation by 100% pure Go. Moreover, it has standard libraries to provide several features such as the Plugin system. Note that we do not intend to reproduce whole of the honorable works of Ruby syntax/implementation/libraries.

One of our goal is to provide web developers a sort of small and handy environment that mainly focusing on creating API servers or microservices. For this, Goby includes the following native features:

  • Robust thread/channel mechanism powered by Go's goroutine
  • Builtin high-performance HTTP server
  • Builtin database library (currently only support PostgreSQL adapter)
  • JSON support
  • Plugin system that can load existing Go packages dynamically (Only for Linux and MacOS right now)
  • Accessing Go objects from Goby directly

Note: Goby had formerly been known as "Rooby", which was renamed in May 2017.

New! Check-out our sample app built with Goby. Source code is also available here.

Structure

Aspects

Goby has several aspects: language specification, design of compiler and vm, implementation (just one for now), library, and the whole of them. See more

We are optimizing and expanding Goby all the time. Toward the first release, we've been focusing on implementing Goby first.

Major Features

  • Plugin system
    • Allows to use Go libraries (packages) dynamically
    • Allows to call Go's methods from Goby directly (only on Linux for now)
  • Builtin multi-threaded server and DB library
  • REPL (run goby -i)

Here's a complete list of all the features.

Current roadmap

  • [ ] create functions for testing framework like rescue, begin -- by 2018 March
  • [ ] testing framework -- by 2018 April
  • [ ] third-party library support (like rubygem)

Installation

Confirmed Goby runs on Mac OS and Linux for now. Try Goby on Windows and let us know the result.

A. Via Homebrew (binary installation for Mac OS)

Note: Please check the latest release before installing Goby via Homebrew

brew tap goby-lang/goby
brew install goby

In the case, $GOBY_ROOT is automatically configured.

B. From Source

Try this if you'd like to contribute Goby! Skip 1 if you already have Golang in your environment.

  1. Prepare Golang environment
    • Install Golang >= 1.10
    • Make sure $GOPATH in your shell's config file( like .bashrc) is correct
    • Add you $GOPATH/bin to $PATH
  2. Run go get github.com/goby-lang/goby
  3. Set the Goby project's exact root path $GOBY_ROOT manually, which should be:
$GOPATH/src/github.com/goby-lang/goby

C. Installation on a Linux system

In order to install Go, Goby and PostgreSQL on a Linux system, see the wiki page.

Verifying Goby installation

  1. Run goby -v to see the version.
  2. Run goby -i to launch igb REPL.
  3. Type require "uri" in igb.

FYI: You can just run brew test goby to check Homebrew installation.

If you have any issue installing Goby, please let us know via Github issues

Using Docker

Goby has official docker image as well. You can try the Plugin System using docker.

Syntax highlighting

The Goby syntax is currently a subset of the Ruby one, with an exception (get_block), therefore, it's possible to attain syntax highlighting on any platform/editor by simply switching it to Ruby for the currently opened file.

Sublime Text 3

Sublime Text 3 users can use the Only Goby package, by typing the following in a terminal:

git clone git@github.com:saveriomiroddi/only-goby-for-sublime-text "$HOME/.config/sublime-text-3/Packages/only-goby-for-sublime-text"

this will automatically apply the Goby syntax highlighting to the .gb files.

Vim

Vim users can use the vim-goby-syntax-highlighting definition, by typing the following in a terminal:

mkdir -p "$HOME/.vim/syntax"
wget -O "$HOME/.vim/syntax/goby.vim" https://raw.githubusercontent.com/saveriomiroddi/vim-goby-syntax-highlighting/master/goby.vim
echo 'au BufNewFile,BufRead *.gb    setf goby' >> "$HOME/.vim/filetype.vim"

this will automatically apply the Goby syntax highlighting to the .gb files.

Sample codes

More sample Goby codes can be found in sample directory.
