# 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.

//===========================================================================================================
// IMPORTANT NOTE:
//
// The methods below make extensive use of the "unsafe" package to obtain the required pointers.
// Beginning in Go 1.3, the garbage collector may release local variables (e.g., incoming arguments, stack
// variables) the pointers reference *before* the API completes.
//
// As a result, in those cases, the code must hint that the variables remain in active by invoking the
// dummy method "use" (see below). Newer versions of Go are planned to change the mechanism to no longer
// require unsafe pointers.
//
// If you add or modify methods, ENSURE protection of local variables through the "use" builtin to inform
// the garbage collector the variables remain in use if:
//
// -- The value is not a pointer (e.g., int32, struct)
// -- The value is not referenced by the method after passing the pointer to Windows
//
// See http://golang.org/doc/go1.3.

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

Logrus has a built in facility for asserting the presence of log messages. This is implemented through the `test` hook and provides:
* decorators for existing logger (`test.NewLocal` and `test.NewGlobal`) which basically just add the `test` hook
* a test logger (`test.NewNullLogger`) that just records log messages (and does not output any):
```go
logger, hook := NewNullLogger()
logger.Error("Hello error")
assert.Equal(1, len(hook.Entries))
assert.Equal(logrus.ErrorLevel, hook.LastEntry().Level)
assert.Equal("Hello error", hook.LastEntry().Message)
