# go-shlex
|
||||||
|
|
||||||
|
go-shlex is a library to make a lexical analyzer like Unix shell for
|
||||||
|
Go.
|
||||||
|
|
||||||
|
## Install
|
||||||
|
|
||||||
|
go get -u "github.com/anmitsu/go-shlex"
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
```go
|
||||||
|
package main

|
||||||
|
)
|
||||||
|
|
||||||
|
func main() {
|
||||||
|
cmd := `cp -Rdp "file name" 'file name2' dir\ name`
|
||||||
|
words, err := shlex.Split(cmd, true)
|
||||||
|
if err != nil {
|
||||||
|
log.Fatal(err)
|
||||||
|
}
|
||||||
|
|
||||||
|
for _, w := range words {

> The Glider Labs SSH server package is dope. —[@bradfitz](https://twitter.com/bradfitz), Go team member
|
||||||
|
|
||||||
|
This Go package wraps the [crypto/ssh
|
||||||
|
package](https://godoc.org/golang.org/x/crypto/ssh) with a higher-level API for
|
||||||
|
building SSH servers. The goal of the API was to make it as simple as using
|
||||||
|
[net/http](https://golang.org/pkg/net/http/), so the API is very similar:
|
||||||
|
|
||||||
|
```go
|
||||||
|
package main
|
||||||
|
|
||||||
|
import (
|
||||||
|
"github.com/gliderlabs/ssh"
|
||||||
|
"io"
|
||||||
|
"log"
|
||||||
|
)
|
||||||
|
|
||||||
|
func main() {
|
||||||
|
ssh.Handle(func(s ssh.Session) {
|
||||||
|
io.WriteString(s, "Hello world\n")
|
||||||
|
})
|
||||||
|
|
||||||
|
log.Fatal(ssh.ListenAndServe(":2222", nil))
|
||||||
|
}
|
||||||
|
|
||||||
|
```
|
||||||
|
This package was built by [@progrium](https://twitter.com/progrium) after working on nearly a dozen projects at Glider Labs using SSH and collaborating with [@shazow](https://twitter.com/shazow) (known for [ssh-chat](https://github.com/shazow/ssh-chat)).
|
||||||
|
|
||||||
|
## Examples
|
||||||
|
|
||||||
|
A bunch of great examples are in the `_examples` directory.
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
[See GoDoc reference.](https://godoc.org/github.com/gliderlabs/ssh)
|
||||||
|
|
||||||
|
## Contributing
|
||||||
|
|
||||||
|
Pull requests are welcome! However, since this project is very much about API
|
||||||
|
design, please submit API changes as issues to discuss before submitting PRs.
|
||||||
|
|
||||||
|
Also, you can [join our Slack](http://slack.gliderlabs.com) to discuss as well.
|
||||||
|
|
||||||
|
## Roadmap
|
||||||
|
|
||||||
|
* Non-session channel handlers
|
||||||
|
* Cleanup callback API
|
||||||
|
* 1.0 release
|
||||||
|
* High-level client?

/*
|
||||||
|
Package ssh wraps the crypto/ssh package with a higher-level API for building
|
||||||
|
SSH servers. The goal of the API was to make it as simple as using net/http, so
|
||||||
|
the API is very similar.
|
||||||
|
|
||||||
|
You should be able to build any SSH server using only this package, which wraps
|
||||||
|
relevant types and some functions from crypto/ssh. However, you still need to
|
||||||
|
use crypto/ssh for building SSH clients.
|
||||||
|
|
||||||
|
ListenAndServe starts an SSH server with a given address, handler, and options. The
|
||||||
|
handler is usually nil, which means to use DefaultHandler. Handle sets DefaultHandler:
|
||||||
|
|
||||||
|
ssh.Handle(func(s ssh.Session) {
|
||||||
|
io.WriteString(s, "Hello world\n")
|
||||||
|
})
|
||||||
|
|
||||||
|
log.Fatal(ssh.ListenAndServe(":2222", nil))
|
||||||
|
|
||||||
|
If you don't specify a host key, it will generate one every time. This is convenient
|
||||||
|
except you'll have to deal with clients being confused that the host key is different.
|
||||||
|
It's a better idea to generate or point to an existing key on your system:
|
||||||
|
|
||||||
|
log.Fatal(ssh.ListenAndServe(":2222", nil, ssh.HostKeyFile("/Users/progrium/.ssh/id_rsa")))
|
||||||
|
|
||||||
|
Although all options have functional option helpers, another way to control the
|
||||||
|
server's behavior is by creating a custom Server:
|
||||||
|
|
||||||
|
s := &ssh.Server{
|
||||||
|
Addr: ":2222",
|
||||||
|
Handler: sessionHandler,
|
||||||
|
PublicKeyHandler: authHandler,
|
||||||
|
}
|
||||||
|
s.AddHostKey(hostKeySigner)
|
||||||
|
|
||||||
|
log.Fatal(s.ListenAndServe())
|
||||||
|
|
||||||
|
This package automatically handles basic SSH requests like setting environment
|
||||||
|
variables, requesting PTY, and changing window size. These requests are
|
||||||
|
processed, responded to, and any relevant state is updated. This state is then
|
||||||
|
exposed to you via the Session interface.
|
||||||
|
|
||||||
|
The one big feature missing from the Session abstraction is signals. This was
|
||||||
|
started, but not completed. Pull Requests welcome!
