# go-ansiterm
This is a cross platform Ansi Terminal Emulation library. It reads a stream of Ansi characters and produces the appropriate function calls. The results of the function calls are platform dependent.
For example the parser might receive "ESC, [, A" as a stream of three characters. This is the code for Cursor Up (http://www.vt100.net/docs/vt510-rm/CUU). The parser then calls the cursor up function (CUU()) on an event handler. The event handler determines what platform specific work must be done to cause the cursor to move up one position.
The parser (parser.go) is a partial implementation of this state machine (http://vt100.net/emu/vt500_parser.png). There are also two event handler implementations, one for tests (test_event_handler.go) to validate that the expected events are being produced and called, the other is a Windows implementation (winterm/win_event_handler.go).
See parser_test.go for examples exercising the state machine and generating appropriate function calls.

// -- The value is not a pointer (e.g., int32, struct)

# go-winio
This repository contains utilities for efficiently performing Win32 IO operations in
Go. Currently, this is focused on accessing named pipes and other file handles, and
for using named pipes as a net transport.
This code relies on IO completion ports to avoid blocking IO on system threads, allowing Go
to reuse the thread to schedule another goroutine. This limits support to Windows Vista and
newer operating systems. This is similar to the implementation of network sockets in Go's net
package.
Please see the LICENSE file for licensing information.

Conduct](https://opensource.microsoft.com/codeofconduct/). For more information

FAQ](https://opensource.microsoft.com/codeofconduct/faq/) or contact

questions or comments.
Thanks to natefinch for the inspiration for this library. See https://github.com/natefinch/npipe
for another named pipe implementation.

// TODO Windows. Identify bug in GOLang 1.5.1+ and/or Windows Server 2016 TP5.
// @jhowardmsft, @swernli.
//
// On Windows, this mitigates a problem with the default options of running
// a docker client against a local docker daemon on TP5.
//
// What was found that if the default host is "localhost", even if the client
// (and daemon as this is local) is not physically on a network, and the DNS
// cache is flushed (ipconfig /flushdns), then the client will pause for
// exactly one second when connecting to the daemon for calls. For example
// using docker run windowsservercore cmd, the CLI will send a create followed
// by an attach. You see the delay between the attach finishing and the attach
// being seen by the daemon.
//
// Here's some daemon debug logs with additional debug spew put in. The
// AfterWriteJSON log is the very last thing the daemon does as part of the
// create call. The POST /attach is the second CLI call. Notice the second
// time gap.

// This does not occur with the docker client built with 1.4.3 on the same
// Windows build, regardless of whether the daemon is built using 1.5.1
// or 1.4.3. It does not occur on Linux. We also verified we see the same thing
// on a cross-compiled Windows binary (from Linux).
//

// to the delay if a user were to do 'docker run -H=tcp://localhost:2375...'
// explicitly.
