// ★ Usable Artifacts
|

|
||
|
||
// Clock Characters:
|
||
//
|
||
// You can put these in constants if you like.
|
||
//
|
||
// Use this for the digits : "█"
|
||
// Use this for the separators : "░"

|
||
// ★ GOAL 1 : Printing the Digits
|
||
// ★ Solution: 02-printing-the-digits
|
||
// ★★★★★★★★★★★★★★★★★★★★★★★★★★★
|
||
|
||
// - [ ] Define a new placeholder type
|
||
// ...
|
||
|
||
// - [ ] Create the digits
|
||
// zero := ...
|
||
// one := ...
|
||
// ...
|
||
|
||
// - [ ] Put them into the "digits" array
|
||
// digits := ...
|
||
|
||
// - [ ] Print them side-by-side
|
||
// - [ ] Loop for all the lines in a digit
|
||
// - [ ] Print each digit line by line
|
||
//
|
||
// - [ ] Don't forget printing a space after each digit
|
||
// - [ ] 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

// ★ GOAL 2 : Printing the Clock
|
||
// ★ Solution: 03-printing-the-clock
|
||
// ★★★★★★★★★★★★★★★★★★★★★★★★★★★
|
||
|
||
// - [ ] Get the current time
|
||
|
||
// - [ ] Get the current hour, minute and second from the current time
|
||
|
||
// - [ ] Create the clock array
|
||
//
|
||
// - [ ] Get the individual digits from the digits array
|
||
//
|
||
// clock := ...
|
||
|
||
// - [ ] Print the clock
|
||
//
|
||
// - [ ] In the loops, use the clocks array instead
|
||
|
||
// - [ ] Create a separator array (it's also a placeholder)
|
||
|
||
// - [ ] Add the separators into the correct positions of
|
||
// the clock array
|
||
|
||
// ★★★★★★★★★★★★★★★★★★★★★★★★★★★
|
||
// ★ GOAL 3 : Updating the Clock
|
||
// ★ Solution: 04-updating-the-clock
|
||
// ★★★★★★★★★★★★★★★★★★★★★★★★★★★
|
||
|
||
// - [ ] Create an infinite loop to update the clock
|
||
|
||
// - [ ] Update the clock every second
|
||
//
|
||
// time.Sleep(time.Second) will stop the world for 1 second
|
||
//
|
||
// See this for more info:
|
||
// https://golang.org/pkg/time/#Sleep
|
||
|
||
// - [ ] Clear the screen before the infinite loop
|
||
//
|
||
// This string value clears the screen when printed:
|
||
//
|
||
// "\033[2J"
|
||
//
|
||
// + For Go Playground, use this instead: "\f"
|
||
//
|
||
// + This only works on bash command prompts.
|
||
|
||
// - [ ] Move the cursor to the top-left corner of the screen before each step
|
||
// of the infinite loop
|
||
//
|
||
// This string value moves the cursor like so when printed:
|
||
//
|
||
// "\033[H"
|
||
//
|
||
// + For Go Playground, use this instead: "\f"
|
||
//
|
||
// + This only works on bash command prompts.
|
||
|
||
// + If you're curious:
|
||
// \033 is a special control code:
|
||
// [2J clears the screen and the cursor
|
||
// [H moves the cursor to 0, 0 screen position

|
||
// ★ GOAL 4: Blinking the Separators
|
||
// ★ Solution: 05-blink-the-separators
|
||
// ★★★★★★★★★★★★★★★★★★★★★★★★★★★
|
||
|
||
// - [ ] Blink the separators
|
||
//
|
||
// They should be visible per two seconds.
|
||
//
|
||
// Example: 1st second 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- Deciding what to print when printing the clock
