示例 #1:
# Ruby code for Symbol.to_proc() method
# declaring Symbol
a = :aBcDeF
# declaring Symbol
b = :"\u{e4 f6 fc}"
# declaring Symbol
c = :ABCDEF
# Symbol
puts "Symbol a : #{a}\n\n"
puts "Symbol b : #{b}\n\n"
puts "Symbol c : #{c}\n\n\n\n"
# to_proc form
puts "Symbol a to_proc form : #{a.to_proc}\n\n"
puts "Symbol b to_proc form : #{b.to_proc}\n\n"
puts "Symbol c to_proc form : #{c.to_proc}\n\n"
输出 :
Symbol a : aBcDeF
Symbol b : äöü
Symbol c : ABCDEF
Symbol a to_proc form : #
Symbol b to_proc form : #
Symbol c to_proc form : #
示例 #2:
