A Golang command line dashboard

[Gizak]

TL;DR: termui

Hi guys!

I was wondering why seems like we don't have a dashboard-like command line ui, so I made some commits and just released a Go command line dashboard termui build upon termbox-go. It is still in active developing, and APIs are subject to change!

Cheers

Wow! Thank you very much for your work. Keep the good work.

Make a theme definition:

type Theme map[string]Attribute

func (t Theme) Lookup(name string) Attribute {}

Names are for example:

"bg"

"fg"

"line"

"border.bg"

"border.fg"

"sparkline.line"

"sparkline.title.fg"

"sparkline.title.bg"

For resolving the names you start by removing the token before the last item, e.g. for resolving "sparkline.title.fg" you check for these attributes...

"sparkline.title.fg"

"sparkline.fg"

"fg"

This allows for more flexibility in defining themes and you can also that way split out the different "widgets" to separate package.

Basically it allows your themes to be composable.

Hey, that is a good idea! Thank you for pointing out! (do you mind I put you in the contributors list after embedding this in codes?)

Sure, go ahead if you like.

Also, introduce a Rect type, maybe something like:

type Rect struct {

Left, Top, Bottom, Right int

}

func NewRect(x, y int, w, h int) Rect {

return Rect{x,y,x+w,y+h }

}

func (r Rect) Inset(pad Rect) Rect {

r.Left += p.Left

r.Top += p.Top

r.Right -= p.Right

r.Bottom -= p.Bottom

}

func (r Rect) Outset(margin Rect) Rect {

r.Left -= p.Left

r.Top -= p.Top

r.Right += p.Right

r.Bottom += p.Bottom

}

type Block struct {

Rect Rect

Padding Rect

inner Rect

Border        labeledBorder

IsDisplay     bool

HasBorder     bool

BgColor       Attribute

}

Alternatively:

type Rect struct {

X, Y int

W, H int

}

type Padding struct {

Left, Top, Right, Bottom int

}

Or you can take the design of http://golang.org/pkg/image/#Rectangle

It should make some of the code nicer.

PS. regarding the theme, you may want to also try out several other designs, e.g.

"": Attributes{ "bg": Attribute{}, "fg": Attribute{}, "line": Attribute{}}

"border": Attributes{ "bg": Attribute{}, "fg": Attribute{}}

"sparkline": Attributes{ "bg": Attribute{}, "fg": Attribute{}, "line": Attribute{}}

"sparkline.title": Attributes{ "bg": Attribute{}, "fg": Attribute{}}

I don't like the "remove the token before the last item", it isn't simple mechanic... maybe explicitly defining the widget and attributes for that widget is better?

Then you would have:

func (t Theme) Lookup(widget, attr string) Attribute {}

e.g.

Lookup("sparkline.title", "bg")

Lookup("sparkline", "bg")

Lookup("", "bg")

And would remove tokens only in the widget name,
