## Introduction

A <b>W</b>eb-based <b>IDE</b> for Teams using Go programming language/Golang.

![Hello, 世界](https://cloud.githubusercontent.com/assets/873584/4606377/d0ca3c2a-521b-11e4-912c-d955ab05850b.png)

## Motivation

* **Team** IDE:
  * _Safe and reliable_: the project source code stored on the server in real time, the developer's machine crashes without losing any source code 
  * _Unified environment_: server unified development environment configuration, the developer machine without any additional configuration 
  * _Out of the box_: 5 minutes to setup a server then open browser to develop, debug
  * _Version Control_: each developer has its own source code repository, easy sync with the trunk 
* **Web-based** IDE:
  * Developer needs a browser only
  * Cross-platform, even on mobile devices
  * Easy to extend
  * Easy to integrate with other systems
  * For the geeks
* A try for commercial-open source: versions customized for enterprises, close to their development work flows respectively
* Currently more popular Go IDE has some defects or regrets: 
  * Text editor (vim/emacs/sublime/Atom, etc.): For the Go newbie is too complex 
  * Plug-in (goclipse, etc.): the need for the original IDE support, not professional
  * LiteIDE: no modern user interface :p
  * No team development experience 
* There are a few of GO IDEs, and no one developed by Go itself, this is a nice try

## Architecture 

### Build & Run

![Build & Run](https://cloud.githubusercontent.com/assets/873584/4389219/3642bc62-43f3-11e4-8d1f-06d7aaf22784.png)

 * A browser tab corresponds to a Wide session
 * Execution output push via WebSocket

Flow: 
 1. Browser sends ````Build```` request
 2. Server executes ````go build```` command via ````os/exec````<br/>
    2.1. Generates a executable file
 3. Browser sends ````Run```` request
 4. Server executes the file via ````os/exec````<br/>
    4.1. A running process<br/>
    4.2. Execution output push via WebSocket channel
 5. Browser renders with callback function ````ws.onmessage````

### Code Assist

 * Autocompletion
 * Find Usages/Jump To Declaration/etc.

Flow: 
 1. Browser sends code assist request
 2. Handler gets user workspace of the request with HTTP session
 3. Server executes ````gocode````/````ide_stub(gotools)````<br/>
    3.1 Sets environment variables (e.g. ${GOPATH})<br/>
    3.2 ````gocode```` with ````lib-path```` parameter
