Strings — Learn bubblecode

Strings are pieces of text enclosed in double quotes. bubblecode has two ways to join strings and several built-in functions for working with them.

Joining strings

Use & to join strings directly (no space) or && to join with a space:

join.bubble

put "Hello" into greeting
put "World" into target
 
say greeting & target
say greeting && target

String functions

bubblecode has built-in functions for common text operations:

strfns.bubble

put "Hello, World!" into text
 
say "Length:" && length(text)
say "Upper:" && uppercase(text)
say "Lower:" && lowercase(text)
say "Reverse:" && reverse(text)

Checking contents

Use contains to check if a string includes a certain word:

contains.bubble

put "I love bubblecode" into text
 
if text contains "bubblecode" then
say "Found it!"
end if
 
if text contains "Python" then
say "Found Python"
else
say "No Python here"
end if

Exercise

Create a variable "first" with value "Hello" and "second" with value "bubblecode". Print them joined with a space using &&.

exercise.bubble

-- Join two strings
put "" into first
put "" into second
say first && second
