Adding code comments
Introduction
Comments are parts of the code that don't get executed.
Why do I need comments?
Comments come in handy in a few situations:
- Annotating - they can describe what a specific part of the code does
- Testing - you can temporarily disable a single section to test a different part
- Documenting - comments can act as a code documentation e.g explain custom functions
With our syntax it's pretty easy to add comments:
// Single line comment
/* Multi
Line
Comment
*/
Single line Comment
A single line comment can be achieved by placing two forward slashes at the beginning of a line:
Code
Let's code something and describe it with a short comment
// this part sums 2 numbers
$let[num1;5]
$let[num2;10]
Result is $sum[$num1;$num2]
Output
Now it's time to check if the comment worked fine
As you see the comment at line 1 didn't appear in the result
Multiple Lines Comment
In some cases you may want to comment out more than one line or a specific part of it. You can do that by wrapping the comment with a combination of slashes and asterisks: /* Comment */
Code
Let's extend our previous comment with some extra lines:
/* This part
Sums two numbers
num1 and num2
and it send the result
*/
$let[num1;5]
$let[num2;10]
result is $sum[$num1;$num2]
Output
Here's what the bot returns:
As you can see it didn't add any extra content despite adding more lines.
