## Description
This library provides basic building blocks for building advanced console UIs.
Initially created for [Gor](http://github.com/buger/gor).
Full API documentation: http://godoc.org/github.com/buger/goterm
## Basic usage
Full screen console app, printing current time:
```go
import (
tm "github.com/buger/goterm"
"time"
)
func main() {
tm.Clear() // Clear current screen
for {
// By moving cursor to top-left position we ensure that console output
// will be overwritten each time, instead of adding new.
tm.MoveCursor(1,1)
tm.Println("Current Time:", time.Now().Format(time.RFC1123))
tm.Flush() // Call it every time at the end of rendering
time.Sleep(time.Second)
}
}
```
This can be seen in [examples/time_example.go](examples/time_example.go). To
run it yourself, go into your `$GOPATH/src/github.com/buger/goterm` directory
and run `go run ./examples/time_example.go`
Print red bold message on white background:
```go
tm.Println(tm.Background(tm.Color(tm.Bold("Important header"), tm.RED), tm.WHITE))
```
Create box and move it to center of the screen:
```go
tm.Clear()
// Create Box with 30% width of current screen, and height of 20 lines
box := tm.NewBox(30|tm.PCT, 20, 0)
// Add some content to the box
// Note that you can add ANY content, even tables
fmt.Fprint(box, "Some box content")
// Move Box to approx center of the screen
tm.Print(tm.MoveTo(box.String(), 40|tm.PCT, 40|tm.PCT))
tm.Flush()
```
This can be found in [examples/box_example.go](examples/box_example.go).
Draw table:
```go
// Based on http://golang.org/pkg/text/tabwriter
totals := tm.NewTable(0, 10, 5, ' ', 0)
fmt.Fprintf(totals, "Time\tStarted\tActive\tFinished\n")
fmt.Fprintf(totals, "%s\t%d\t%d\t%d\n", "All", started, started-finished, finished)
tm.Println(totals)
tm.Flush()
```
This can be found in [examples/table_example.go](examples/table_example.go).
## Line charts
Chart example:

```go
import (
tm "github.com/buger/goterm"
)
chart := tm.NewLineChart(100, 20)
data := new(tm.DataTable)
data.AddColumn("Time")
data.AddColumn("Sin(x)")
data.AddColumn("Cos(x+1)")
for i := 0.1; i < 10; i += 0.1 {
data.AddRow(i, math.Sin(i), math.Cos(i+1))
}
tm.Println(chart.Draw(data))
```
This can be found in [examples/chart_example.go](examples/chart_example.go).
Drawing 2 separate graphs in different scales. Each graph have its own Y axe.
```go
chart.Flags = tm.DRAW_INDEPENDENT
```
Drawing graph with relative scale (Grapwh draw starting from min value instead of zero)
```go
chart.Flags = tm.DRAW_RELATIVE
```
