# I have this string:

# 

# Color1 R=144 G=248 B=255

# 

# Need regular expression for get R,G,B

# How I can simplify it:

# 

# lines.gsub!(/Color1 R=(\d+) G=(\d+) B=(\d+)/) {

# puts $1

# puts $2

# puts $3

# }

irb(main):026:0\> s = “Color1 R=144 G=248 B=255”  
=\> “Color1 R=144 G=248 B=255”  
irb(main):030:0\> r,g,b=(/R=(\d+)\s+G=(\d+)\s+B=(\d+)/).match(s).captures  
=\> [“144”, “248”, “255”]  
irb(main):031:0\> r  
=\> “144”  
irb(main):032:0\> g  
=\> “248”  
irb(main):033:0\> b  
=\> “255”
