# 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
//

Package symlink implements EvalSymlinksInScope which is an extension of filepath.EvalSymlinks,
as well as a Windows long-path aware version of filepath.EvalSymlinks
Package symlink implements EvalSymlinksInScope which is an extension of filepath.EvalSymlinks
from the [Go standard library](https://golang.org/pkg/path/filepath).
The code from filepath.EvalSymlinks has been adapted in fs.go.
