If you get an error claiming that lazygit cannot be found or is not defined, you may need to add `~/go/bin` to your $PATH (MacOS/Linux), or `%HOME%\go\bin` (Windows)
### Ubuntu
Packages for Ubuntu 14.04 and up are available via Launchpad PPA.
They are built daily, straight from master branch.
```sh
sudo add-apt-repository ppa:lazygit-team/daily
sudo apt-get update
sudo apt-get install lazygit
```
## Cool features
- Adding files easily
- Resolving merge conflicts
- Easily check out recent branches
- Scroll through logs/diffs of branches/commits/stash
- Scroll through logs/diffs of branches/commits/stash
- Quick pushing/pulling
- Squash down and rename commits

## Contributing
I'll find a good template for contributing and then add it to the repo (or if somebody has a suggestion please put up a PR)
## Work in progress
This is still a work in progress so there's still bugs to iron out and as this is my first project in Go the code could no doubt use an increase in quality, but I'll be improving on it whenever I find the time. If you have any feedback feel free to raise an issue/submit a PR.

/*
Package color is an ANSI color package to output colorized or SGR defined
output to the standard output. The API can be used in several way, pick one
that suits you.
Use simple and default helper functions with predefined foreground colors:
color.Cyan("Prints text in cyan.")
// a newline will be appended automatically
color.Blue("Prints %s in blue.", "text")
// More default foreground colors..
color.Red("We have red")
color.Yellow("Yellow color too!")
color.Magenta("And many others ..")
// Hi-intensity colors
color.HiGreen("Bright green color.")
color.HiBlack("Bright black means gray..")
color.HiWhite("Shiny white color!")
However there are times where custom color mixes are required. Below are some
examples to create custom color objects and use the print functions of each
separate color object.
// Create a new color object
c := color.New(color.FgCyan).Add(color.Underline)
c.Println("Prints cyan text with an underline.")
// Or just add them to New()
d := color.New(color.FgCyan, color.Bold)
d.Printf("This prints bold cyan %s\n", "too!.")
// Mix up foreground and background colors, create new mixes!
red := color.New(color.FgRed)
boldRed := red.Add(color.Bold)
boldRed.Println("This will print text in bold red.")
whiteBackground := red.Add(color.BgWhite)
whiteBackground.Println("Red text with White background.")
// Use your own io.Writer output
color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
blue := color.New(color.FgBlue)
blue.Fprint(myWriter, "This will print text in blue.")
You can create PrintXxx functions to simplify even more:
// Create a custom print function for convenient
red := color.New(color.FgRed).PrintfFunc()
red("warning")
red("error: %s", err)
// Mix up multiple attributes
notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
notice("don't forget this...")
You can also FprintXxx functions to pass your own io.Writer:
blue := color.New(FgBlue).FprintfFunc()
blue(myWriter, "important notice: %s", stars)
// Mix up with multiple attributes
success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
success(myWriter, don't forget this...")
Or create SprintXxx functions to mix strings with other non-colorized strings:
yellow := New(FgYellow).SprintFunc()
red := New(FgRed).SprintFunc()
fmt.Printf("this is a %s and this is %s.\n", yellow("warning"), red("error"))
info := New(FgWhite, BgGreen).SprintFunc()
fmt.Printf("this %s rocks!\n", info("package"))
Windows support is enabled by default. All Print functions work as intended.
However only for color.SprintXXX functions, user should use fmt.FprintXXX and
set the output to color.Output:
fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
info := New(FgWhite, BgGreen).SprintFunc()
fmt.Fprintf(color.Output, "this %s rocks!\n", info("package"))
Using with existing code is possible. Just use the Set() method to set the
standard output to the given parameters. That way a rewrite of an existing
code is not required.
// Use handy standard colors.
color.Set(color.FgYellow)
fmt.Println("Existing text will be now in Yellow")
fmt.Printf("This one %s\n", "too")
color.Unset() // don't forget to unset
// You can mix up parameters
color.Set(color.FgMagenta, color.Bold)
defer color.Unset() // use it in your function
fmt.Println("All text will be now bold magenta.")
There might be a case where you want to disable color output (for example to
pipe the standard output of your app to somewhere else). `Color` has support to
disable colors both globally and for single color definition. For example
suppose you have a CLI app and a `--no-color` bool flag. You can easily disable
the color output with:
var flagNoColor = flag.Bool("no-color", false, "Disable color output")
if *flagNoColor {
color.NoColor = true // disables colorized output
}
It also has support for single color definitions (local). You can
disable/enable color output on the fly:
c := color.New(color.FgCyan)
c.Println("Prints cyan text")
c.DisableColor()
c.Println("This is printed without any color")
c.EnableColor()
c.Println("This prints again cyan...")

Package gocui allows to create console user interfaces.
Create a new GUI:
g, err := gocui.NewGui(gocui.OutputNormal)
if err != nil {
// handle error
}
defer g.Close()
// Set GUI managers and key bindings
// ...
if err := g.MainLoop(); err != nil && err != gocui.ErrQuit {
// handle error
}
Set GUI managers:
g.SetManager(mgr1, mgr2)
Managers are in charge of GUI's layout and can be used to build widgets. On
each iteration of the GUI's main loop, the Layout function of each configured
manager is executed. Managers are used to set-up and update the application's
main views, being possible to freely change them during execution. Also, it is
important to mention that a main loop iteration is executed on each reported
event (key-press, mouse event, window resize, etc).
GUIs are composed by Views, you can think of it as buffers. Views implement the
io.ReadWriter interface, so you can just write to them if you want to modify
their content. The same is valid for reading.
Create and initialize a view with absolute coordinates:
if v, err := g.SetView("viewname", 2, 2, 22, 7); err != nil {
if err != gocui.ErrUnknownView {
// handle error
}
fmt.Fprintln(v, "This is a new view")
// ...
}
Views can also be created using relative coordinates:
maxX, maxY := g.Size()
if v, err := g.SetView("viewname", maxX/2-30, maxY/2, maxX/2+30, maxY/2+2); err != nil {
// ...
}
Configure keybindings:
if err := g.SetKeybinding("viewname", gocui.KeyEnter, gocui.ModNone, fcn); err != nil {
// handle error
}
gocui implements full mouse support that can be enabled with:
g.Mouse = true
Mouse events are handled like any other keybinding:
if err := g.SetKeybinding("viewname", gocui.MouseLeft, gocui.ModNone, fcn); err != nil {
// handle error
}
IMPORTANT: Views can only be created, destroyed or updated in three ways: from
the Layout function within managers, from keybinding callbacks or via
*Gui.Update(). The reason for this is that it allows gocui to be
concurrent-safe. So, if you want to update your GUI from a goroutine, you must
use *Gui.Update(). For example:
g.Update(func(g *gocui.Gui) error {
v, err := g.View("viewname")
if err != nil {
// handle error
}
v.Clear()
fmt.Fprintln(v, "Writing from different goroutines")
return nil
})
By default, gocui provides a basic edition mode. This mode can be extended
and customized creating a new Editor and assigning it to *View.Editor:
type Editor interface {
Edit(v *View, key Key, ch rune, mod Modifier)
}
DefaultEditor can be taken as example to create your own custom Editor:
var DefaultEditor Editor = EditorFunc(simpleEditor)
func simpleEditor(v *View, key Key, ch rune, mod Modifier) {
switch {
case ch != 0 && mod == 0:
v.EditWrite(ch)
case key == KeySpace:
v.EditWrite(' ')
case key == KeyBackspace || key == KeyBackspace2:
v.EditDelete(true)
// ...
}
}
Colored text:
Views allow to add colored text using ANSI colors. For example:
fmt.Fprintln(v, "\x1b[0;31mHello world")
For more information, see the examples in folder "_examples/".
