* _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 - -## Features - -* [X] Code Highlight, Folding: Go/HTML/JavaScript/Markdown etc. -* [X] Autocomplete: Go/HTML etc. -* [X] Format: Go/HTML/JSON etc. -* [X] Build & Run -* [X] Multiplayer: a real team development experience -* [X] Navigation, Jump to declaration, Find usages, File search etc. -* [X] Shell: run command on the server -* [X] Web development: HTML/JS/CSS editor with [Emmet](https://emmet.io) integrated -* [X] Go tool: go get/install/fmt etc. -* [X] File Import & Export -* [X] Themes: editor and UI adjust, respectively -* [X] Cross-Compilation -* [ ] Debug -* [ ] Git integration: git command on the web -

-## Pull Requests - -### Contributor License Agreement - -fsnotify is derived from code in the [golang.org/x/exp](https://godoc.org/golang.org/x/exp) package and it may be included [in the standard library](https://github.com/go-fsnotify/fsnotify/issues/1) in the future. Therefore fsnotify carries the same [LICENSE](https://github.com/go-fsnotify/fsnotify/blob/master/LICENSE) as Go. Contributors retain their copyright, so you need to fill out a short form before we can accept your contribution: [Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual). - -Please indicate that you have signed the CLA in your pull request. - -### How fsnotify is Developed - -* Development is done on feature branches. -* Tests are run on BSD, Linux, OS X and Windows. -* Pull requests are reviewed and [applied to master][am] using [hub][]. - * Maintainers may modify or squash commits rather than asking contributors to. -* To issue a new release, the maintainers will: - * Update the CHANGELOG - * Tag a version, which will become available through gopkg.in. - -### How to Fork - -For smooth sailing, always use the original import path. Installing with `go get` makes this easy. - -1. Install from GitHub (`go get -u github.com/go-fsnotify/fsnotify`) -2. Create your feature branch (`git checkout -b my-new-feature`) -3. Ensure everything works and the tests pass (see below) -4. Commit your changes (`git commit -am 'Add some feature'`) - -Contribute upstream: - -1. Fork fsnotify on GitHub -2. Add your remote (`git remote add fork git@github.com:mycompany/repo.git`) -3. Push to the branch (`git push fork my-new-feature`) -4. Create a new Pull Request on GitHub - -This workflow is [thoroughly explained by Katrina Owen](https://blog.splice.com/contributing-open-source-git-repositories-go/). - -### Testing - -fsnotify uses build tags to compile different code on Linux, BSD, OS X, and Windows. - -Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on. - -To aid in cross-platform testing there is a Vagrantfile for Linux and BSD. - -* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/) -* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder. -* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password) -* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd go-fsnotify/fsnotify; go test'`. -* When you're done, you will want to halt or destroy the Vagrant boxes. - -Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory. - -Right now there is no equivalent solution for Windows and OS X, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads). - -### Maintainers - -Help maintaining fsnotify is welcome. To be a maintainer: - -* Submit a pull request and sign the CLA as above. -* You must be able to run the test suite on Mac, Windows, Linux and BSD. - -To keep master clean, the fsnotify project uses the "apply mail" workflow outlined in Nathaniel Talbott's post ["Merge pull request" Considered Harmful][am]. This requires installing [hub][]. - -All code changes should be internal pull requests. - -Releases are tagged using [Semantic Versioning](http://semver.org/). - -[hub]: https://github.com/github/hub -[am]: http://blog.spreedly.com/2014/06/24/merge-pull-request-considered-harmful/#.VGa5yZPF_Zs diff --git a/vendor/github.com/go-fsnotify/fsnotify/LICENSE b/vendor/github.com/go-fsnotify/fsnotify/LICENSE deleted file mode 100644 index f21e540..0000000 --- a/vendor/github.com/go-fsnotify/fsnotify/LICENSE +++ /dev/null @@ -1,28 +0,0 @@ -Copyright (c) 2012 The Go Authors.

We're ignoring the error resulted from decoding an - // existing session: Get() always returns a session, even if empty. - session, _ := store.Get(r, "session-name") - // Set some session values. - session.Values["foo"] = "bar" - session.Values[42] = 43 - // Save it. - session.Save(r, w) - } - -First we initialize a session store calling NewCookieStore() and passing a -secret key used to authenticate the session. Inside the handler, we call -store.Get() to retrieve an existing session or a new one. Then we set some -session values in session.Values, which is a map[interface{}]interface{}. -And finally we call session.Save() to save the session in the response. - -Note that in production code, we should check for errors when calling -session.Save(r, w), and either display an error message or otherwise handle it. - -Important Note: If you aren't using gorilla/mux, you need to wrap your handlers -with context.ClearHandler as or else you will leak memory! An easy way to do this -is to wrap the top-level mux when calling http.ListenAndServe: - - http.ListenAndServe(":8080", context.ClearHandler(http.DefaultServeMux)) - -The ClearHandler function is provided by the gorilla/context package. - -That's all you need to know for the basic usage. Let's take a look at other -options, starting with flash messages. - -Flash messages are session values that last until read. The term appeared with -Ruby On Rails a few years back. When we request a flash message, it is removed -from the session. To add a flash, call session.AddFlash(), and to get all -flashes, call session.Flashes(). Here is an example: - - func MyHandler(w http.ResponseWriter, r *http.Request) { - // Get a session. - session, _ := store.Get(r, "session-name") - // Get the previously flashes, if any. - if flashes := session.Flashes(); len(flashes) > 0 { - // Just print the flash values. - fmt.Fprint(w, "%v", flashes) - } else { - // Set a new flash. - session.AddFlash("Hello, flash messages world!") - fmt.Fprint(w, "No flashes found.") - } - session.Save(r, w) - } - -Flash messages are useful to set information to be read after a redirection, -like after form submissions. - -There may also be cases where you want to store a complex datatype within a -session, such as a struct. Sessions are serialised using the encoding/gob package, -so it is easy to register new datatypes for storage in sessions: - - import( - "encoding/gob" - "github.com/gorilla/sessions" - ) - - type Person struct { - FirstName string - LastName string - Email string - Age int - } - - type M map[string]interface{} - - func init() { - - gob.Register(&Person{}) - gob.Register(&M{}) - } - -As it's not possible to pass a raw type as a parameter to a function, gob.Register() -relies on us passing it an empty pointer to the type as a parameter. In the example -above we've passed it a pointer to a struct and a pointer to a custom type -representing a map[string]interface. This will then allow us to serialise/deserialise -values of those types to and from our sessions. - -By default, session cookies last for a month. This is probably too long for -some cases, but it is easy to change this and other attributes during -runtime. Sessions can be configured individually or the store can be -configured and then all sessions saved using it will use that configuration. -We access session.Options or store.Options to set a new configuration. The -fields are basically a subset of http.Cookie fields. Let's change the -maximum age of a session to one week: - - session.Options = &sessions.Options{ - Path: "/", - MaxAge: 86400 * 7, - HttpOnly: true, - } - -Sometimes we may want to change authentication and/or encryption keys without -breaking existing sessions. The CookieStore supports key rotation, and to use -it you just need to set multiple authentication and encryption keys, in pairs, -to be tested in order: - - var store = sessions.NewCookieStore( - []byte("new-authentication-key"), - []byte("new-encryption-key"), - []byte("old-authentication-key"), - []byte("old-encryption-key"), - ) - -New sessions will be saved using the first pair. Old sessions can still be -read because the first pair will fail, and the second will be tested. This -makes it easy to "rotate" secret keys and still be able to validate existing -sessions. Note: for all pairs the encryption key is optional; set it to nil -or omit it and and encryption won't be used. - -Multiple sessions can be used in the same request, even with different -session backends. When this happens, calling Save() on each session -individually would be cumbersome, so we have a way to save all sessions -at once: it's sessions.Save(). Here's an example: - - var store = sessions.NewCookieStore([]byte("something-very-secret")) - - func MyHandler(w http.ResponseWriter, r *http.Request) { - // Get a session and set a value. - session1, _ := store.Get(r, "session-one") - session1.Values["foo"] = "bar" - // Get another session and set another value. - session2, _ := store.Get(r, "session-two") - session2.Values[42] = 43 - // Save all sessions. - sessions.Save(r, w) - } - -This is possible because when we call Get() from a session store, it adds the -session to a common registry. Save() uses it to save all registered sessions. -*/ -package sessions diff --git a/vendor/github.com/gorilla/sessions/sessions.go b/vendor/github.com/gorilla/sessions/sessions.go deleted file mode 100644 index 53111b3..0000000 --- a/vendor/github.com/gorilla/sessions/sessions.go +++ /dev/null @@ -1,234 +0,0 @@ -// Copyright 2012 The Gorilla Authors.

RFC 6455 Features
Passes Autobahn Test SuiteYesNo
Receive fragmented messageYesNo, see note 1
Send close messageYesNo
Send pings and receive pongsYesNo
Get the type of a received data messageYesYes, see note 2
Other Features
Limit size of received messageYesNo
Read message using io.ReaderYesNo, see note 3
Write message using io.WriteCloserYesNo, see note 3
- -Notes: - -1. Large messages are fragmented in [Chrome's new WebSocket implementation](http://www.ietf.org/mail-archive/web/hybi/current/msg10503.html). -2. The application can get the type of a received data message by implementing - a [Codec marshal](http://godoc.org/golang.org/x/net/websocket#Codec.Marshal) - function. -3. The go.net io.Reader and io.Writer operate across WebSocket frame boundaries. - Read returns when the input buffer is full or a frame boundary is - encountered. Each call to Write sends a single frame message. The Gorilla - io.Reader and io.WriteCloser operate on a single WebSocket message. - diff --git a/vendor/github.com/gorilla/websocket/client.go b/vendor/github.com/gorilla/websocket/client.go deleted file mode 100644 index 93db8dd..0000000 --- a/vendor/github.com/gorilla/websocket/client.go +++ /dev/null @@ -1,269 +0,0 @@ -// Copyright 2013 The Gorilla WebSocket Authors.

Call the connection WriteControl, WriteMessage or NextWriter -// methods to send a control message to the peer. -// -// Connections handle received ping and pong messages by invoking a callback -// function set with SetPingHandler and SetPongHandler methods. These callback -// functions can be invoked from the ReadMessage method, the NextReader method -// or from a call to the data message reader returned from NextReader. -// -// Connections handle received close messages by returning an error from the -// ReadMessage method, the NextReader method or from a call to the data message -// reader returned from NextReader. -// -// Concurrency -// -// Connections do not support concurrent calls to the write methods -// (NextWriter, SetWriteDeadline, WriteMessage) or concurrent calls to the read -// methods methods (NextReader, SetReadDeadline, ReadMessage). Connections do -// support a concurrent reader and writer. -// -// The Close and WriteControl methods can be called concurrently with all other -// methods. -// -// Read is Required -// -// The application must read the connection to process ping and close messages -// sent from the peer. If the application is not otherwise interested in -// messages from the peer, then the application should start a goroutine to read -// and discard messages from the peer.

It provides several advanced capabilities, which currently includes: - - - Context-sensitive autocompletion - -It is called *daemon*, because it uses client/server architecture for caching purposes. In particular, it makes autocompletions very fast. Typical autocompletion time with warm cache is 30ms, which is barely noticeable. - -Also watch the [demo screencast](http://nosmileface.ru/images/gocode-demo.swf). - -![Gocode in vim](http://nosmileface.ru/images/gocode-screenshot.png) - -![Gocode in emacs](http://nosmileface.ru/images/emacs-gocode.png) - -### Setup - - 1. You should have a correctly installed Go compiler environment and your personal workspace ($GOPATH). If you have no idea what **$GOPATH** is, take a look [here](http://golang.org/doc/code.html). Please make sure that your **$GOPATH/bin** is available in your **$PATH**. This is important, because most editors assume that **gocode** binary is available in one of the directories, specified by your **$PATH** environment variable. Otherwise manually copy the **gocode** binary from **$GOPATH/bin** to a location which is part of your **$PATH** after getting it in step 2. - - Do these steps only if you understand why you need to do them: - - `export GOPATH=$HOME/goprojects` - - `export PATH=$PATH:$GOPATH/bin` - - 2. Then you need to get the appropriate version of the gocode, for 6g/8g/5g compiler you can do this: - - `go get -u github.com/nsf/gocode` (-u flag for "update") - - Windows users should consider doing this instead: - - `go get -u -ldflags -H=windowsgui github.com/nsf/gocode` - - That way on the Windows OS gocode will be built as a GUI application and doing so solves hanging window issues with some of the editors. - - 3. Next steps are editor specific. See below. - -### Vim setup - -#### Vim manual installation - -Note: As of go 1.5 there is no $GOROOT/misc/vim script. Suggested installation is via [vim-go plugin](https://github.com/fatih/vim-go). - -In order to install vim scripts, you need to fulfill the following steps: - - 1. Install official Go vim scripts from **$GOROOT/misc/vim**. If you did that already, proceed to the step 2. - - 2. Install gocode vim scripts. Usually it's enough to do the following: - - 2.1. `vim/update.sh` - - **update.sh** script does the following: - - #!/bin/sh - mkdir -p "$HOME/.vim/autoload" - mkdir -p "$HOME/.vim/ftplugin/go" - cp "${0%/*}/autoload/gocomplete.vim" "$HOME/.vim/autoload" - cp "${0%/*}/ftplugin/go/gocomplete.vim" "$HOME/.vim/ftplugin/go" - - 2.2. Alternatively, you can create symlinks using symlink.sh script in order to avoid running update.sh after every gocode update. - - **symlink.sh** script does the following: - - #!/bin/sh - cd "${0%/*}" - ROOTDIR=`pwd` - mkdir -p "$HOME/.vim/autoload" - mkdir -p "$HOME/.vim/ftplugin/go" - ln -s "$ROOTDIR/autoload/gocomplete.vim" "$HOME/.vim/autoload/" - ln -s "$ROOTDIR/ftplugin/go/gocomplete.vim" "$HOME/.vim/ftplugin/go/" - - 3. Make sure vim has filetype plugin enabled. Simply add that to your **.vimrc**: - - `filetype plugin on` - - 4. Autocompletion should work now. Use `` for autocompletion (omnifunc autocompletion). - -#### Using Vundle in Vim - -Add the following line to your **.vimrc**: - -`Plugin 'nsf/gocode', {'rtp': 'vim/'}` - -And then update your packages by running `:PluginInstall`. - -#### Using vim-plug in Vim - -Add the following line to your **.vimrc**: - -`Plug 'nsf/gocode', { 'rtp': 'vim', 'do': '~/.vim/plugged/gocode/vim/symlink.sh' }` - -And then update your packages by running `:PlugInstall`. - -#### Other - -Alternatively take a look at the vundle/pathogen friendly repo: https://github.com/Blackrush/vim-gocode. - -### Neovim setup -#### Neovim manual installation - - Neovim users should also follow `Vim manual installation`, except that you should goto `gocode/nvim` in step 2, and remember that, the Neovim configuration file is `~/.config/nvim/init.vim`. - -#### Using Vundle in Neovim - -Add the following line to your **init.vim**: - -`Plugin 'nsf/gocode', {'rtp': 'nvim/'}` - -And then update your packages by running `:PluginInstall`. - -#### Using vim-plug in Neovim - -Add the following line to your **init.vim**: - -`Plug 'nsf/gocode', { 'rtp': 'nvim', 'do': '~/.config/nvim/plugged/gocode/nvim/symlink.sh' }` - -And then update your packages by running `:PlugInstall`. - -### Emacs setup - -In order to install emacs script, you need to fulfill the following steps: - - 1. Install [auto-complete-mode](http://www.emacswiki.org/emacs/AutoComplete) - - 2. Copy **emacs/go-autocomplete.el** file from the gocode source distribution to a directory which is in your 'load-path' in emacs. - - 3. Add these lines to your **.emacs**: - - (require 'go-autocomplete) - (require 'auto-complete-config) - (ac-config-default) - -Also, there is an alternative plugin for emacs using company-mode. See `emacs-company/README` for installation instructions. - -If you're a MacOSX user, you may find that script useful: https://github.com/purcell/exec-path-from-shell. It helps you with setting up the right environment variables as Go and gocode require it. By default it pulls the PATH, but don't forget to add the GOPATH as well, e.g.: - -``` -(when (memq window-system '(mac ns)) - (exec-path-from-shell-initialize) - (exec-path-from-shell-copy-env "GOPATH")) -``` - -### Options - -You can change all available options using `gocode set` command. The config file uses json format and is usually stored somewhere in **~/.config/gocode** directory. On windows it's stored in the appropriate AppData folder. It's suggested to avoid modifying config file manually, do that using the `gocode set` command. - -`gocode set` lists all options and their values. - -`gocode set
