# 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.

GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.
0. Additional Definitions.
As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.
"The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.
An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.
A "Combined Work" is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".
The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:
a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or
b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:
a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license
document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:
a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form
suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version of
the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.
1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time
a copy of the Library already present on the user's computer
system, and (b) will operate properly with a modified version
of the Library that is interface-compatible with the Linked
Version.
e) Provide Installation Information, but only if you would otherwise
be required to provide such information under section 6 of the
GNU GPL, and only to the extent that such information is
necessary to install and execute a modified version of the
Combined Work produced by recombining or relinking the
Application with a modified version of the Linked Version. (If
you use option 4d0, the Installation Information must accompany
the Minimal Corresponding Source and Corresponding Application
Code. If you use option 4d1, you must provide the Installation
Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based
on the Library, uncombined with any other library facilities,
conveyed under the terms of this License.
b) Give prominent notice with the combined library that part of it
is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

# ansiterm
import "github.com/juju/ansiterm"
Package ansiterm provides a Writer that writes out the ANSI escape
codes for color and styles.
## type Color
``` go
type Color int
```
Color represents one of the standard 16 ANSI colors.
``` go
const (
Default Color
Black
Red
Green
Yellow
Blue
Magenta
Cyan
Gray
DarkGray
BrightRed
BrightGreen
BrightYellow
BrightBlue
BrightMagenta
BrightCyan
White
)
```
### func (Color) String
``` go
func (c Color) String() string
```
String returns the name of the color.
## type Context
``` go
type Context struct {
Foreground Color
Background Color
Styles []Style
}
```
Context provides a way to specify both foreground and background colors
along with other styles and write text to a Writer with those colors and
styles.
### func Background
``` go
func Background(color Color) *Context
```
Background is a convenience function that creates a Context with the
specified color as the background color.
### func Foreground
``` go
func Foreground(color Color) *Context
```
Foreground is a convenience function that creates a Context with the
specified color as the foreground color.
### func Styles
``` go
func Styles(styles ...Style) *Context
```
Styles is a convenience function that creates a Context with the
specified styles set.
### func (\*Context) Fprint
``` go
func (c *Context) Fprint(w sgrWriter, args ...interface{})
```
Fprint will set the sgr values of the writer to the specified foreground,
background and styles, then formats using the default formats for its
operands and writes to w. Spaces are added between operands when neither is
a string. It returns the number of bytes written and any write error
encountered.
### func (\*Context) Fprintf
``` go
func (c *Context) Fprintf(w sgrWriter, format string, args ...interface{})
```
Fprintf will set the sgr values of the writer to the specified
foreground, background and styles, then write the formatted string,
then reset the writer.
### func (\*Context) SetBackground
``` go
func (c *Context) SetBackground(color Color) *Context
```
SetBackground sets the background to the specified color.
### func (\*Context) SetForeground
``` go
func (c *Context) SetForeground(color Color) *Context
```
SetForeground sets the foreground to the specified color.
### func (\*Context) SetStyle
``` go
func (c *Context) SetStyle(styles ...Style) *Context
```
SetStyle replaces the styles with the new values.
## type Style
``` go
type Style int
```
``` go
const (
Bold Style
Faint
Italic
Underline
Blink
Reverse
Strikethrough
Conceal
)
```
### func (Style) String
``` go
func (s Style) String() string
```
## type TabWriter
``` go
type TabWriter struct {
Writer
// contains filtered or unexported fields
}
```
TabWriter is a filter that inserts padding around tab-delimited
columns in its input to align them in the output.
It also setting of colors and styles over and above the standard
tabwriter package.
### func NewTabWriter
``` go
func NewTabWriter(output io.Writer, minwidth, tabwidth, padding int, padchar byte, flags uint) *TabWriter
```
NewTabWriter returns a writer that is able to set colors and styels.
The ansi escape codes are stripped for width calculations.
### func (\*TabWriter) Flush
``` go
func (t *TabWriter) Flush() error
```
Flush should be called after the last call to Write to ensure
that any data buffered in the Writer is written to output. Any
incomplete escape sequence at the end is considered
complete for formatting purposes.
### func (\*TabWriter) Init
``` go
func (t *TabWriter) Init(output io.Writer, minwidth, tabwidth, padding int, padchar byte, flags uint) *TabWriter
```
A Writer must be initialized with a call to Init. The first parameter (output)
specifies the filter output. The remaining parameters control the formatting:
minwidth minimal cell width including any padding
tabwidth width of tab characters (equivalent number of spaces)
padding padding added to a cell before computing its width
padchar ASCII char used for padding
if padchar == '\t', the Writer will assume that the
width of a '\t' in the formatted output is tabwidth,
and cells are left-aligned independent of align_left
(for correct-looking results, tabwidth must correspond
to the tab width in the viewer displaying the result)
flags formatting control
## type Writer
``` go
type Writer struct {
io.Writer
// contains filtered or unexported fields
}
```
Writer allows colors and styles to be specified. If the io.Writer
is not a terminal capable of color, all attempts to set colors or
styles are no-ops.
### func NewWriter
``` go
func NewWriter(w io.Writer) *Writer
```
NewWriter returns a Writer that allows the caller to specify colors and
styles. If the io.Writer is not a terminal capable of color, all attempts
to set colors or styles are no-ops.
### func (\*Writer) ClearStyle
``` go
func (w *Writer) ClearStyle(s Style)
```
ClearStyle clears the text style.
### func (\*Writer) Reset
``` go
func (w *Writer) Reset()
```
Reset returns the default foreground and background colors with no styles.
### func (\*Writer) SetBackground
``` go
func (w *Writer) SetBackground(c Color)
```
SetBackground sets the background color.
### func (\*Writer) SetForeground
``` go
func (w *Writer) SetForeground(c Color)
```
SetForeground sets the foreground color.
### func (\*Writer) SetStyle
``` go
func (w *Writer) SetStyle(s Style)
```
SetStyle sets the text style.

// Filter implementation
// A cell represents a segment of text terminated by tabs or line breaks.
// The text itself is stored in a separate buffer; cell only describes the
// segment's size in bytes, its width in runes, and whether it's an htab
// ('\t') terminated cell.
//
type cell struct {
size int // cell size in bytes
width int // cell width in runes
htab bool // true if the cell is terminated by an htab ('\t')
}
// A Writer is a filter that inserts padding around tab-delimited
// columns in its input to align them in the output.
//
// The Writer treats incoming bytes as UTF-8 encoded text consisting
// of cells terminated by (horizontal or vertical) tabs or line
// breaks (newline or formfeed characters). Cells in adjacent lines
// constitute a column. The Writer inserts padding as needed to
// make all cells in a column have the same width, effectively
// aligning the columns. It assumes that all characters have the
// same width except for tabs for which a tabwidth must be specified.
// Note that cells are tab-terminated, not tab-separated: trailing
// non-tab text at the end of a line does not form a column cell.
//
// The Writer assumes that all Unicode code points have the same width;
// this may not be true in some fonts.
//
// If DiscardEmptyColumns is set, empty columns that are terminated
// entirely by vertical (or "soft") tabs are discarded. Columns
// terminated by horizontal (or "hard") tabs are not affected by
// this flag.
//
// If a Writer is configured to filter HTML, HTML tags and entities
// are passed through. The widths of tags and entities are
// assumed to be zero (tags) and one (entities) for formatting purposes.
//
// A segment of text may be escaped by bracketing it with Escape
// characters. The tabwriter passes escaped text segments through
// unchanged. In particular, it does not interpret any tabs or line
// breaks within the segment. If the StripEscape flag is set, the
// Escape characters are stripped from the output; otherwise they
// are passed through as well. For the purpose of formatting, the
// width of the escaped text is always computed excluding the Escape
// characters.
//
// The formfeed character ('\f') acts like a newline but it also
// terminates all columns in the current line (effectively calling
// Flush). Cells in the next line start new columns. Unless found
// inside an HTML tag or inside an escaped text segment, formfeed
// characters appear as newlines in the output.

vtclean
----
Clean up raw terminal output by stripping escape sequences, optionally preserving color.
Get it: `go get github.com/lunixbochs/vtclean/vtclean`
API:
import "github.com/lunixbochs/vtclean"
vtclean.Clean(line string, color bool) string
Command line example:
$ echo -e '\x1b[1;32mcolor example
color forced to stop at end of line
backspace is ba\b\bgood
no beeps!\x07\x07' | ./vtclean -color
color example
color forced to stop at end of line
backspace is good
no beeps!
Go example:
package main
import (
"fmt"
"github.com/lunixbochs/vtclean"
)
func main() {
line := vtclean.Clean(
"\033[1;32mcolor, " +
"curs\033[Aor, " +
"backspace\b\b\b\b\b\b\b\b\b\b\b\033[K", false)
fmt.Println(line)
}
Output:
color, cursor

# Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age,
body size, disability, ethnicity, gender identity and expression, level of
experience, nationality, personal appearance, race, religion, or sexual
identity and orientation.
## Our Standards
Examples of behaviour that contributes to creating a positive environment
include:
- Using welcoming and inclusive language
- Being respectful of differing viewpoints and experiences
- Gracefully accepting constructive criticism
- Focusing on what is best for the community
- Showing empathy towards other community members
Examples of unacceptable behaviour by participants include:
- The use of sexualized language or imagery and unwelcome sexual attention or
advances
- Trolling, insulting/derogatory comments, and personal or political attacks
- Public or private harassment
- Publishing others' private information, such as a physical or electronic
address, without explicit permission
- Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behaviour and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behaviour.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviours that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an
appointed representative at an online or offline event. Representation of a
project may be further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at
[hello@manifold.co](mailto:hello@manifold.co). All complaints will be reviewed
and investigated and will result in a response that is deemed necessary and
appropriate to the circumstances. The project team is obligated to maintain
confidentiality with regard to the reporter of an incident. Further details of
specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the Contributor Covenant, version 1.4,
available at
[http://contributor-covenant.org/version/1/4](http://contributor-covenant.org/version/1/4).

# promptui
Interactive prompt for command-line applications.
We built Promptui because we wanted to make it easy and fun to explore cloud services with [manifold cli](https://github.com/manifoldco/manifold-cli).

## Overview
![promptui](https://media.giphy.com/media/xUNda0Ngb5qsogLsBi/giphy.gif)
Promptui is a library providing a simple interface to create command-line
prompts for go. It can be easily integrated into
[spf13/cobra](https://github.com/spf13/cobra),
[urfave/cli](https://github.com/urfave/cli) or any cli go application.
Promptui has two main input modes:
- `Prompt` provides a single line for user input. Prompt supports
optional live validation, confirmation and masking the input.
- `Select` provides a list of options to choose from. Select supports
pagination, search, detailed view and custom templates.
For a full list of options check [GoDoc](https://godoc.org/github.com/manifoldco/promptui).
## Basic Usage
### Prompt
```go
package main
import (
"errors"
"fmt"
"strconv"
"github.com/manifoldco/promptui"
)
func main() {
validate := func(input string) error {
_, err := strconv.ParseFloat(input, 64)
if err != nil {
return errors.New("Invalid number")
}
return nil
}
prompt := promptui.Prompt{
Label: "Number",
Validate: validate,
}
result, err := prompt.Run()
if err != nil {
fmt.Printf("Prompt failed %v\n", err)
return
}
fmt.Printf("You choose %q\n", result)
}
```
### Select
```go
package main
import (
"fmt"
"github.com/manifoldco/promptui"
)
func main() {
prompt := promptui.Select{
Label: "Select Day",
Items: []string{"Monday", "Tuesday", "Wednesday", "Thursday", "Friday",
"Saturday", "Sunday"},
}
_, result, err := prompt.Run()
if err != nil {
fmt.Printf("Prompt failed %v\n", err)
return
}
fmt.Printf("You choose %q\n", result)
}
```

Colorable writer for windows.
For example, most of logger packages doesn't show colors on windows. (I know we can do it with ansicon. But I don't want.)
This package is possible to handle escape sequence for ansi color on windows.
## Too Bad!
![](https://raw.githubusercontent.com/mattn/go-colorable/gh-pages/bad.png)
## So Good!
![](https://raw.githubusercontent.com/mattn/go-colorable/gh-pages/good.png)
## Usage
```go
logrus.SetFormatter(&logrus.TextFormatter{ForceColors: true})
logrus.SetOutput(colorable.NewColorableStdout())
logrus.Info("succeeded")
logrus.Warn("not correct")
logrus.Error("something error")
logrus.Fatal("panic")
```
You can compile above code on non-windows OSs.
## Installation
```
$ go get github.com/mattn/go-colorable
