# GOAL 1: Printing the Digits
|
||||
|
||||
## Challenge Steps
|
||||
|
||||
1. Define a new placeholder type
|
||||
|
||||
2. Create the digits from "zero" to "nine"
|
||||
|
||||
You can use these characters for the clock:
|
||||
|
||||
```
|
||||
Digit character : █
|
||||
Separator character : ░
|
||||
```
|
||||
|
||||
1. Put them into the "digits" array
|
||||
|
||||
2. Print the digits side-by-side
|
||||
|
||||
1. Loop for all the lines in a digit
|
||||
|
||||
2. Print each digit line by line
|
||||
|
||||
3. Don't forget printing a space after each digit
|
||||
|
||||
4. Don't forget printing a newline after each line
|
||||
|
||||
EXAMPLE: Let's say you want to print 10.
|
||||
|
||||
```
|
||||
██ ███ <--- Print a new line after printing a single line from
|
||||
█ █ █ all the digits.
|
||||
█ █ █
|
||||
█ █ █
|
||||
███ ███
|
||||
^^
|
||||
||
|
||||
++----> Add space between the digits
|
||||
```
|
||||
|
||||
## Solution
|
||||
|
||||
You can find the solution in the solution folder.

## Notes
|
||||
|
||||
* Note main.go file contains the solution of the previous step.
|
||||
* "solution" folder contains the solution for this step.
|
||||
|
||||
## Challenge Steps
|
||||
|
||||
1. Get the current time
|
||||
|
||||
2. Get the current hour, minute and second from the current time
|
||||
|
||||
3. Create the clock array by getting the digits from the digits array
|
||||
|
||||
4. Print the clock by using the clock array
|
||||
|
||||
5. Create a separator array (it's also a placeholder type)
|
||||
|
||||
6. Add the separators into the correct positions of the clock array

## Notes

* Note main.go file contains the solution of the previous step.
|

|

|
||||
## Challenge Steps
|
||||
|
||||
1. Create an infinite loop to update the clock
|
||||
|
||||
2. Update the clock every second
|
||||
|
||||
[time.Sleep(time.Second)](https://golang.org/pkg/time/#Sleep) will stop the world for 1 second
|
||||
|
||||
3. Clear the screen before the infinite loop
|
||||
|
||||
1. Get my library for clearing the screen:
|
||||
|
||||
`go get -u github.com/inancgumus/screen`
|
||||
|
||||
2. Then, import it and call it in your code like this:
|
||||
|
||||
`screen.Clear()`
|
||||
|
||||
3. If you're using Go Playground instead, do this:
|
||||
|
||||
`fmt.Println("\f")`
|
||||
|
||||
4. Move the cursor to the top-left corner of the screen, before each step
|
||||
of the infinite loop
|
||||
|
||||
* Call this in your code like this:
|
||||
|
||||
`screen.MoveTopLeft()`
|
||||
|
||||
* If you're using Go Playground instead, do this again:
|
||||
|
||||
`fmt.Println("\f")`
|
||||
|
||||

|
||||
|
||||
## SIDE NOTE FOR THE CURIOUS
|
||||
|
||||
If you're curious about how my screen clearing package works, read on.
|
||||
|
||||
**On bash**, it uses special commands, if you open the code, you can see that.
|
||||
|
||||
* `\033` is a special control code:
|
||||
* `[2J` clears the screen and the cursor
|
||||
* `[H` moves the cursor to 0, 0 screen position
|
||||
* [See for more information](https://bluesock.org/~willkg/dev/ansi.html).
|
||||
|
||||
**On Windows**, I'm directly calling the Windows API functions. This is way advanced at this stage of the course, however, I'll probably explain it afterward.
|
||||
|
||||
So, my package automatically adjusts itself depending on where it is compiled. On Windows, it uses the special Windows API calls; On other operating systems, it uses the bash special commands that I've explained above.

# GOAL 4: Blinking the Separators
|
||||
|
||||
## Notes
|
||||
|
||||
* Note main.go file contains the solution of the previous step.
|
||||
* "solution" folder contains the solution for this step.
|
||||
|
||||
## Challenge Steps
|
||||
|
||||
Separators should be visible once in every two seconds.
|
||||
|
||||
### Example:
|
||||
|
||||
* 1st second: They're invisible
|
||||
* 2nd second: visible
|
||||
* 3rd second: invisible
|
||||
* 4th second: visible
|
||||
|
||||
### HINT
|
||||
|
||||
There are two ways to do this:
|
||||
|
||||
1. Manipulating the clock array directly (by adding/removing the separators)
|
||||
|
||||
2. Or: Deciding what placeholders to print when printing the clock
