eolib-go

Core library for writing Endless Online applications using the Go programming language.

Usage

Referencing the package

The library may be referenced in a project via go get:

go get github.com/ethanmoffat/eolib-go@v2.0.1

Sample code

A sample server skeleton using eolib-go is available here.

Development Environment

Installing go

Development was done using go 1.20.5 on Ubuntu Linux. Development on Windows is untested.

gvm is recommended as a mechanism to manage installations of different versions of go.

To set up gvm on Linux using bash:

bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)
source $HOME/.gvm/scripts/gvm

The source command may be added to your ~/.bash_profile so gvm is available in all login shells.

echo "source $HOME/.gvm/scripts/gvm" >> ~/.bash_profile

Once gvm is installed and sourced, use the following commands to install and use go 1.20.5:

gvm install go1.20.5 -B
gvm use go1.20.5

The gvm use command is required on each subsequent terminal or session in which go commands must be run.

VSCode setup

If go is installed via gvm, you must update your $GOROOT variable to point at it, or VSCode won't be able to find the go binary.

Get the path to the GOROOT via go env:

~ [ethan@BEASTMODE] $  gvm use go1.20.5
Now using version go1.20.5
~ [ethan@BEASTMODE] $  go env GOROOT
/home/ethan/.gvm/gos/go1.20.5

In VSCode, search for the GOROOT setting and update the path to point at this version of go.

Note that a gvm extension exists for VSCode but it is out of date and no longer functions properly.

Building the code

A Makefile is provided to ease the process of building, testing, and code generation. Use make help to see all available targets. Running make by itself should be enough for most uses. make test is also available to run all tests.

Building the library on Windows is left as an exercise to the reader.
