Hi all, here is my question:

Lets say that I have a variable:

aString =3D "1234s * 4234k"

I'll then like to scan for the units (the s and the k) after each integer:

anArray =3D aString.scan(/s/)

Well that got me the s, but what expression do I have to use, if I want to
scan for both s and k?

aString = "1234s * 4234k"

Well that got me the s, but what expression do I have to use, if I want to
scan for both s and k?

p "1234s * 4234k".scan(/\d+[sk]/)

Greetings,

Lets say that I have a variable:

anArray =3D aString.scan(/s/)

Well that got me the s, but what expression do I have to use, if I want t= o
scan for both s and k?

if you have an explicit list:
anArray =3D aString.scan(/[sk]/) #=3D> ["s", "k"]

if you just want any lowercase letter:
anArray =3D aString.scan(/[a-z]/) #=3D> ["s", "k"]

String.scan takes a regex, you might want to look into that. Have fun!
