The say command

say is bubblecode’s primary output command. It prints a value followed by a newline.

say "Hello, World!"
say 42
say 2 + 2
say "The answer is" && (6 * 7)

You can print any expression: strings, numbers, arithmetic, or variables.

Printing without newlines

Use & and && within a single say to build up a line:

put "Alice" into name
put 95 into score
 
say name & ": " & score & " points"
say name && "scored" && score && "points"

Empty lines

Pass an empty string to say to print a blank line.

say "First section"
say ""
say "Second section"

Comments

Lines beginning with -- are comments. The interpreter ignores them entirely.

-- This is a comment
say "This runs"
 
-- You can use comments to explain intent
-- or temporarily disable code:
-- say "This is commented out"
 
say "Done"

Comments are invaluable for explaining why your code does something, not just what it does.

The tab function

Use tab(n) to indent output by n tab stops (each is 2 spaces).

say "Items:"
say tab(1) & "Apple"
say tab(1) & "Banana"
say tab(2) & "(organic)"
say tab(1) & "Cherry"
