Preconditions:

1. Create workspace from the Go stack with desktop-go-simple project.
2. Enable Golang language server in the Installers tab and start the workspace.
3. Create "format.go" file with content:

package
main

import (

	   "fmt"
	"math"

)

func    print(   ) {
	   fmt.Printf("Hello, world. Sqrt(2) = %v\n",  math.Sqrt(2))
}

4. Create "main.go" file with content:

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Printf("Hello, world. Sqrt(2) = %v\n", math.Sqrt(2))
}

5. Create "print.go" file with content:

package main

import (
	"fmt"
)

const COLOR_RED = "\x1b[31;1m "
const COLOR_GREEN = "\x1b[32;1m "
const COLOR_YELLOW = "\x1b[33;1m "
const COLOR_BLACK = "\x1b[34;1m "

func Print(color string, s string) {
	fmt.Printf("%s %s\n", color, s)
}

6. Create "towers.go" file with content:

package main

import (
	"fmt"
)

var count int

func hanoi(n int, a, b, c string) {
	if n == 1 {
		count++
		Print(COLOR_GREEN, fmt.Sprintf("Step %d: move disk from %s to %s\n", count, a, c))
		return
	}

	hanoi(n-1, a, c, b)
	count++
	Print(COLOR_YELLOW, fmt.Sprintf("Step %d: move disk from %s to %s\n", count, a, c))
	hanoi(n-1, b, a, c)
}

func main() {
	hanoi(3, "1", "2", "3")
}

Testing process

• Language server initialization

1. From the project open "main.go" file.
2. Check Finished running tool: /usr/local/go/bin/go build message in the dev-machine console.

• Autocomplete feature

2. Create a new line on line 10.
3. Add fmt.P code and launch autocomplete by Ctrl+Space.
4. Check that proposal Printfis present.
5. Delete created line.

• Find definition feature

1. Open "towers.go" file.
2. Set cursor to 12:5 position and invoke Assistant -> Find Definition. The "print.go" file should be opened and function Print should be selected.
3. Close the print.go file. And repeat previous step using F4 key instead of Assistant -> Find Definition invocation.

• Code validation feature, Comment line

1. Open "main.go" file.
2. Move cursor in 1:1 position.
3. Type p symbol there and check that error marker is appeared. Click on error marker - the proposal widget should be show expected 'package', found 'IDENT' ppackage message.
4. Restore content. Error marker should disappear.
5. Move cursor in line 1 position and comment this line by Ctrl+/ buttons.
6. Check that text in line 3 was changed from package main to //package main.
7. Uncomment this line by Ctrl+/ buttons.

• Hover feature

1. Open "towers.go" file.
2. Move mouse pointer on position 12:15
3. Wait hover popup is appeared with text const COLOR_YELLOW string = "\x1b[33;1m ".
4. Move mouse pointer on position 22:8
5. Wait hover popup is appeared with text main redeclared in this block previous declaration at.

• Format code feature

1. Open "format.go" file.
2. Start Format option from context menu;
3. Check that the file content was changed to:

package main

import (
	"fmt"
	"math"
)

func print() {
	fmt.Printf("Hello, world. Sqrt(2) = %v\n", math.Sqrt(2))
}

Rename

1. Open "towers.py" file.
2. Select "n" variable in line 10.
3. Start Rename feature by Shift+F6 or from Assistant menu.
4. Type new variable name.

Find References

1. Open "towers.py" file.
2. Select count variable
3. Start Find References feature by pressing Alt+F7 buttons or from Assistant menu.
4. Check that Find References panel is opened with /desktop-go-simple/towers.go From:7:5 To:7:10 result in it.

Signature Help

1. Open "towers.go" file.
2. Type hanoi on line 24.
3. Type '(' symbol and wait for hover popup with hanoi(n int, a, b, c string) text.
4. Delete added line.

Go To Symbol

1. Open "towers.go" file.
2. Start Go To Symbol feature by Ctrl+F12 buttons or from Assistant menu.
