# 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.

# 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.
This project has adopted the [Microsoft Open Source Code of
Conduct](https://opensource.microsoft.com/codeofconduct/). For more information
see the [Code of Conduct
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.

# Exponential Backoff [![GoDoc][godoc image]][godoc] [![Build Status][travis image]][travis] [![Coverage Status][coveralls image]][coveralls]
This is a Go port of the exponential backoff algorithm from [Google's HTTP Client Library for Java][google-http-java-client].
[Exponential backoff][exponential backoff wiki]
is an algorithm that uses feedback to multiplicatively decrease the rate of some process,
in order to gradually find an acceptable rate.
The retries exponentially increase and stop increasing when a certain threshold is met.
## Usage
See https://godoc.org/github.com/cenkalti/backoff#pkg-examples
## Contributing
* I would like to keep this library as small as possible.
* Please don't send a PR without opening an issue and discussing it first.
* If proposed change is not a common use case, I will probably not accept it.

/*
ExponentialBackOff is a backoff implementation that increases the backoff
period for each retry attempt using a randomization function that grows exponentially.
NextBackOff() is calculated using the following formula:
randomized interval =
RetryInterval * (random value in range [1 - RandomizationFactor, 1 + RandomizationFactor])
In other words NextBackOff() will range between the randomization factor
percentage below and above the retry interval.
For example, given the following parameters:
RetryInterval = 2
RandomizationFactor = 0.5
Multiplier = 2
the actual backoff period used in the next retry attempt will range between 1 and 3 seconds,
multiplied by the exponential, that is, between 2 and 6 seconds.
Note: MaxInterval caps the RetryInterval and not the randomized interval.
If the time elapsed since an ExponentialBackOff instance is created goes past the
MaxElapsedTime, then the method NextBackOff() starts returning backoff.Stop.
The elapsed time can be reset by calling Reset().
Example: Given the following default arguments, for 10 tries the sequence will be,
and assuming we go over the MaxElapsedTime on the 10th try:
Request # RetryInterval (seconds) Randomized Interval (seconds)
1 0.5 [0.25, 0.75]
2 0.75 [0.375, 1.125]
3 1.125 [0.562, 1.687]
4 1.687 [0.8435, 2.53]
5 2.53 [1.265, 3.795]
6 3.795 [1.897, 5.692]
7 5.692 [2.846, 8.538]
8 8.538 [4.269, 12.807]
9 12.807 [6.403, 19.210]
10 19.210 backoff.Stop

# ChangeLog
### 1.4 - 2016-07-25
* [#60][60] Support dynamic autocompletion
* Fix ANSI parser on Windows
* Fix wrong column width in complete mode on Windows
* Remove dependent package "golang.org/x/crypto/ssh/terminal"
### 1.3 - 2016-05-09
* [#38][38] add SetChildren for prefix completer interface
* [#42][42] improve multiple lines compatibility
* [#43][43] remove sub-package(runes) for gopkg compatibility
* [#46][46] Auto complete with space prefixed line
* [#48][48] support suspend process (ctrl+Z)
* [#49][49] fix bug that check equals with previous command
* [#53][53] Fix bug which causes integer divide by zero panicking when input buffer is empty
### 1.2 - 2016-03-05
* Add a demo for checking password strength [example/readline-pass-strength](https://github.com/chzyer/readline/blob/master/example/readline-pass-strength/readline-pass-strength.go), , written by [@sahib](https://github.com/sahib)
* [#23][23], support stdin remapping
* [#27][27], add a `UniqueEditLine` to `Config`, which will erase the editing line after user submited it, usually use in IM.
* Add a demo for multiline [example/readline-multiline](https://github.com/chzyer/readline/blob/master/example/readline-multiline/readline-multiline.go) which can submit one SQL by multiple lines.
* Supports performs even stdin/stdout is not a tty.
* Add a new simple apis for single instance, check by [here](https://github.com/chzyer/readline/blob/master/std.go). It need to save history manually if using this api.
* [#28][28], fixes the history is not working as expected.
* [#33][33], vim mode now support `c`, `d`, `x (delete character)`, `r (replace character)`
### 1.1 - 2015-11-20
* [#12][12] Add support for key `<Delete>`/`<Home>`/`<End>`
* Only enter raw mode as needed (calling `Readline()`), program will receive signal(e.g. Ctrl+C) if not interact with `readline`.
* Bugs fixed for `PrefixCompleter`
* Press `Ctrl+D` in empty line will cause `io.EOF` in error, Press `Ctrl+C` in anytime will cause `ErrInterrupt` instead of `io.EOF`, this will privodes a shell-like user experience.
* Customable Interrupt/EOF prompt in `Config`
* [#17][17] Change atomic package to use 32bit function to let it runnable on arm 32bit devices
* Provides a new password user experience(`readline.ReadPasswordEx()`).
### 1.0 - 2015-10-14
* Initial public release.
