红宝石 |符号 =~函数

Symbol#=~() : =~()是一个 Symbol 类方法,它 =~es 带有符号的模式。

示例 #1:

# Ruby code for Symbol.=~() 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"
  
  
# =~ form 
puts "Symbol a =~ form : #{a.=~(/D/)}\n\n"
puts "Symbol b =~ form : #{b.=~(/o/)}\n\n"
puts "Symbol c =~ form : #{c.=~(/C/)}\n\n"

输出 :

Symbol a : aBcDeF

Symbol b : äöü

Symbol c : ABCDEF



Symbol a =~ form : 3

Symbol b =~ form : 

Symbol c =~ form : 2

示例 #2:

# Ruby code for Symbol.=~() method
  
# declaring Symbol 
a = :geeks
  
# declaring Symbol
b = :"\u{e5 f6 f3}"
  
# declaring Symbol
c = :GEEKS
  
# Symbol 
puts "Symbol a : #{a}\n\n"
puts "Symbol b : #{b}\n\n"
puts "Symbol c : #{c}\n\n\n\n"
  
  
# =~ form 
puts "Symbol a =~ form : #{a.=~(/g/)}\n\n"
puts "Symbol b =~ form : #{b.=~(/a/)}\n\n"
puts "Symbol c =~ form : #{c.=~(/EE/)}\n\n"

输出 :

Symbol a : geeks

Symbol b : åöó

Symbol c : GEEKS



Symbol a =~ form : 0

Symbol b =~ form : 

Symbol c =~ form : 1
