the question of install

When I installed by goland, it reported an error.
The error was:
fatal: unable to access 'https://github.com/moul/gotty-client/': Received HTTP code 504 from proxy after CONNECT
package github.com/moul/gotty-client/tree/master/cmd/gotty-client: exit status 128

Hope to get your help, thx

Action signature deprecated

"I contact the distributor of this application" 😁

DEPRECATED Action signature.  Must be `cli.ActionFunc`.  This is an error in the application.  Please contact the distributor of this application if this is not you.  See https://github.com/codegangsta/cli/blob/master/CHANGELOG.md#deprecated-cli-app-action-signature

Execute sequential commands using a script through gotty-client

I want to execute a setup script which contains sql commands like creating a role, assigning privileges to a user etc..
gotty-client does have a command parameter but the documentation is not clear on how we can use it to execute sql scripts on the command line.

gotty-client [global options] command [command options] GOTTY_URL

Is this possible with the current gotty-client, if yes could someone point me to the documentation.

Thanks.

gotty-client hangs on connection

gotty: v2.0.0-alpha.3
gotty-client: v1.6.1

I've tried setting GOTTY_CLIENT_GOTTY2=1 but it does not solve this.

Oddly my help documentation does not print the same as what's in the README.md. There is no mention of --v2.

should unscape basic authentication token for request on /ws

I add commit to unescape basic authentication token. (f20d24e)

However, I forgot to unescape basic authentication token for request on /ws.
(https://github.com/moul/gotty-client/blob/master/gotty-client.go#L122)

It is weird there is no 401 error on websocket request.

On gotty side,
wrapBasicAuth should also take care about ws endpoint.

https://github.com/yudai/gotty/blob/master/server/server.go#L208-L209

func (server *Server) setupHandlers(ctx context.Context, cancel context.CancelFunc, pathPrefix string, counter *counter) http.Handler {
	staticFileHandler := http.FileServer(
		&assetfs.AssetFS{Asset: Asset, AssetDir: AssetDir, Prefix: "static"},
	)

	var siteMux = http.NewServeMux()
	siteMux.HandleFunc(pathPrefix, server.handleIndex)
	siteMux.Handle(pathPrefix+"js/", http.StripPrefix(pathPrefix, staticFileHandler))
	siteMux.Handle(pathPrefix+"favicon.png", http.StripPrefix(pathPrefix, staticFileHandler))
	siteMux.Handle(pathPrefix+"css/", http.StripPrefix(pathPrefix, staticFileHandler))

	siteMux.HandleFunc(pathPrefix+"auth_token.js", server.handleAuthToken)
	siteMux.HandleFunc(pathPrefix+"config.js", server.handleConfig)

	siteHandler := http.Handler(siteMux)

	if server.options.EnableBasicAuth {
		log.Printf("Using Basic Authentication")
		siteHandler = server.wrapBasicAuth(siteHandler, server.options.Credential)
	}

	withGz := gziphandler.GzipHandler(server.wrapHeaders(siteHandler))
	siteHandler = server.wrapLogger(withGz)

	wsMux := http.NewServeMux()
	wsMux.Handle("/", siteHandler)
	wsMux.HandleFunc(pathPrefix+"ws", server.generateHandleWS(ctx, cancel, counter))
	siteHandler = http.Handler(wsMux)

	return siteHandler
}

Building from release tarball is a mess

Building from the 1.6 release tarball is a mess. It requires setting up a bunch of symlinks to various things to get the Makefile to build the target and the Makefile lacks an install target.

Resume binary releases

I see that the newest binary release is at https://github.com/moul/gotty-client/releases/tag/v1.9.0 (November 2020).
Any chance of resuming the binary releases?

Terminal output Issues

• terminal output is cut off (easily reproducible with the top command)
• terminal output is messed up when the terminal is resized
• 'inappropriate ioctl for device' warning when resizing terminal

[documentation] Detaching from gotty session

Hi there!
As far as I can see, there is no any info anywhere even about the simple case: detach from remote gotty session (when you're done and want to leave). 😀
It is neither documented in README, nor in gotty-client's help, not even on the internets (as far as I googled) 🤔

Request:basic authentication implements

I am looking forward to the implementation of BASIC-AUTH.
thanks.

[BUG] Golang Install

Describe the bug
The Golang install with go version go1.14.4 linux/amd64 produces too many errors to install.

To Reproduce
On Ubuntu 18.04 LTS I've done the following to install / setup golang, gotty, and gotty client.

# Download latest from https://golang.org/dl/
wget -c https://golang.org/dl/go1.14.4.linux-amd64.tar.gz

# Check sum
sha256sum go1.14.4.linux-amd64.tar.gz | grep aed845e4185a0b2a3c3d5e1d0a35491702c55889192bb9c30e67a3de6849c067

# Extract to /usr/local
sudo tar -C /usr/local/ -xvzf go1.14.4.linux-amd64.tar.gz

# Set environment variables
export GOPATH="$HOME/go"
export GOBIN="$GOPATH/bin"
export PATH=$PATH:/usr/local/go/bin:$GOBIN

# Install GoTTy (works)
go get github.com/yudai/gotty

# Install GoTTy-client (fails)
go get github.com/moul/gotty-client/cmd/gotty-client

The output I get from trying to install gotty-client is as follows.

I'm not very familiar with Go but I assumed if I had gotty running correctly then I could simply install gotty-client without any additional setup, using the command you have in the README.

Thank you for your help!

Do not warn about websocket closed connection after a ctrl+q request

Possible to package gotty-client into astilectron

[BUG] Should handle EINTR

It keeps disconnected when using go1.14.11 or go1.15.4.
I think since golang/go#38033, golang handles EINTR.

To Reproduce
Steps to reproduce the behavior:

1. Using Golang >= 1.15
2. It keeps disconnected.

Expected behavior
Keep connected

Versions (please complete the following information, if relevant):

• Software version: 1.8.0
• OS: Ubuntu
• Golang version: 1.15.4

Additional context
Add any other context about the problem here.

Add a changelog in the README.md

Authorization support [feature request]

Since GoTTY server supports credentials settings and authorization i think it would be nice to have this in gotty-client too

Terminal disfunction when exiting client

Hey,

When I use the client, each time I quit (Ctrl + Q) my terminal is behaving very weird. Here is how it looks when I try ls:

I'm not sure what is causing it, maybe SIGWINCH..

Tried with and without tmux, bash and zsh

Any ideas?

Add binary releases

Hi,

Is it possible to get binary releases for various platforms (my own interest goes to linux-armv7) like gotty does ?

Thanks,
Arno
