notificator
===========================
Desktop notification with Golang for:
* Windows with `growlnotify`;
* Mac OS X with `terminal-notifier` (if installed) or `osascript` (native, 10.9 Mavericks or Up.);
* Linux with `notify-send` for Gnome and `kdialog` for Kde.
Usage
------
```go
package main
import (
"github.com/0xAX/notificator"
)
var notify *notificator.Notificator
func main() {
notify = notificator.New(notificator.Options{
DefaultIcon: "icon/default.png",
AppName: "My test App",
})
notify.Push("title", "text", "/home/user/icon.png", notificator.UR_CRITICAL)
}
```
TODO
-----
* Add more options for different notificators.
Сontribution
------------
* Fork;
* Make changes;
* Send pull request;
* Thank you.

[termui]() is a cross-platform, easy-to-compile, and fully-customizable terminal dashboard. It aims to provide a terminal front end for your applications with less struggle:
> ![dashboard](img/dashboard.gif)
>
> _cast under osx 10.10; Terminal.app; Menlo Regular 12pt._
This guide describes the essential parts used to build a interface, which includes:
- Installation & Usage
- Layout System
- Event System
- Theming
- Components
[Quickstart](quickstart.md) is the way to go for starters and [Recipes](recipes.md) contains some practical resolutions you might need.

Overview
---
termui offers two layout system: [Absolute]() and [Grid](). The two concept actually spawned from Web:
- The __Absolute layout__ is a plain coordination system, like [CSS position property](https://developer.mozilla.org/en/docs/Web/CSS/position) `position: absolute`. You will need manually assign `.X`, `.Y`, `.Width` and `.Height` to a component.
- The __Grid system__ actually is a simplified version of [the 12 columns CSS grid system](http://www.w3schools.com/bootstrap/bootstrap_grid_system.asp) on terminal. You do not need to bother setting positions and width properties, these values will be synced up according to their containers.
!!! note
`Align` property can help you set your component position based on terminal window. Find more at [Magic Variables](#magic-variables)
__Cons and pros:__
- Use of Absolute layout gives you maximum control over how to arrange your components, while you have
to put a little more effort to set things up. Fortunately there are some "magic variables" may help you out.
- Grid layout can save you some time, it adjusts components location and size based on it's container. But note that you do need to set `.Height` property to each components because termui can not decide it for you.

Installation
---
Since [termui](https://github.com/gizak/termui) is a Go lib, we will need a working Go environment to begin with. If you have not set it up, there is a great intro you can follow up: [How to write Go code](https://golang.org/doc/code.html).
Once you have the environment set up, you can proceed to install termui by the following command:
`go get github.com/gizak/termui`
The current version of termui is v2. If you are working with the old version of termui or the new version does not seem right to you, you can always go back to v1 version by:
`go get gopkg.in/gizak/termui.v1`
!!! note
v2 has many features implemented which you can not find in v1, such as new event system and asynchronous rendering. To find more about versions difference in section [Versions](versions.md).
Usage
---
Let's throw an simple example to get our feet wet:
```go
package main
import ui "github.com/gizak/termui" // use ui as an alias
func main() {
err := ui.Init()
if err != nil {
panic(err)
}
defer ui.Close()
p := ui.NewPar(":PRESS q TO QUIT DEMO")
p.Height = 3
p.Width = 50
p.TextFgColor = ui.ColorWhite
p.BorderLabel = "Text Box"
p.BorderFg = ui.ColorCyan
ui.Render(p) // feel free to call Render, it's async and non-block
ui.Handle("/sys/kbd/q",func(e ui.Event){
ui.StopLoop()
})
ui.Loop()
}
```
There are only around 20 lines for the main function. Break this down into 4 parts:
1. __Init termui__:
`ui.Init()` initializes the termui. From this point, termui will take over your terminal display.
`ui.Close()` closes resources and cleans up your terminal content. Make sure it is called before exit or you will end up with a messed up looking terminal.
2. __Build your component__:
`ui.NewPar(:PRESS q TO QUIT DEMO)` returns a structure representing a paragraph component. You can assign position, size, text colour, border and many other properties to a component.
3. __Draw your component on display__:
`ui.Render(p)` renders p onto terminal display.
4. __Handle events__:
`ui.Handle("/sys/kbd/q", func(e Event))` registers an event handler for event: key q is pressed.
`ui.StopLoop()` exits the event listening loop invoked by `ui.Loop()`.
`ui.Loop()` makes the program stops at here and start listening & handling events. Call
`ui.StopLoop()` to leave the circle.
The example code gives us:
> ![example screenshot](img/demo1.png)
Now you can press q to quit the program.
After knowing of some basics, next we can discover more about:
1. how to set component location in [Layouts](layouts.md)
2. how to capture and handle events in [Events](events.md)
3. the different [components](components.md)
4. check out some real world examples in [recipes](recipes.md)

# The plan9 package provides access to the raw system call
# interface of the underlying operating system. Porting Go to
# a new architecture/operating system combination requires
# some manual effort, though there are tools that automate
# much of the process. The auto-generated files have names
# beginning with z.
#
# This script runs or (given -n) prints suggested commands to generate z files
# for the current system. Running those commands is not automatic.
# This script is documentation more than anything else.
#
# * asm_${GOOS}_${GOARCH}.s
#
# This hand-written assembly file implements system call dispatch.
# There are three entry points:
#
# func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
# func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr);
# func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
#
# The first and second are the standard ones; they differ only in
# how many arguments can be passed to the kernel.
# The third is for low-level use by the ForkExec wrapper;
# unlike the first two, it does not call into the scheduler to
# let it know that a system call is running.
#
# * syscall_${GOOS}.go
#
# This hand-written Go file implements system calls that need
# special handling and lists "//sys" comments giving prototypes
# for ones that can be auto-generated. Mksyscall reads those
# comments to generate the stubs.
#
# * syscall_${GOOS}_${GOARCH}.go
#
# Same as syscall_${GOOS}.go except that it contains code specific
# to ${GOOS} on one particular architecture.
#
# * types_${GOOS}.c
#
# This hand-written C file includes standard C headers and then
# creates typedef or enum names beginning with a dollar sign
# (use of $ in variable names is a gcc extension). The hardest
# part about preparing this file is figuring out which headers to
# include and which symbols need to be #defined to get the
# actual data structures that pass through to the kernel system calls.
# Some C libraries present alternate versions for binary compatibility
# and translate them on the way in and out of system calls, but
# there is almost always a #define that can get the real ones.
# See types_darwin.c and types_linux.c for examples.
#
# * zerror_${GOOS}_${GOARCH}.go
#
# This machine-generated file defines the system's error numbers,
# error strings, and signal numbers. The generator is "mkerrors.sh".
# Usually no arguments are needed, but mkerrors.sh will pass its
# arguments on to godefs.
#
# * zsyscall_${GOOS}_${GOARCH}.go
#
# Generated by mksyscall.pl; see syscall_${GOOS}.go above.
#
# * zsysnum_${GOOS}_${GOARCH}.go
#
# Generated by mksysnum_${GOOS}.

// Package plan9 contains an interface to the low-level operating system
// primitives. OS details vary depending on the underlying system, and
// by default, godoc will display the OS-specific documentation for the current
// system. If you want godoc to display documentation for another
// system, set $GOOS and $GOARCH to the desired system. For example, if
// you want to view documentation for freebsd/arm on linux/amd64, set $GOOS
// to freebsd and $GOARCH to arm.
// The primary use of this package is inside other packages that provide a more
// portable interface to the system, such as "os", "time" and "net". Use
// those packages rather than this one if you can.
// For details of the functions and data types in this package consult
// the manuals for the appropriate operating system.
// These calls return err == nil to indicate success; otherwise
// err represents an operating system error describing the failure and
// holds a value of type syscall.ErrorString.
