    I vote for the closure of this issue as not relevant to the topic, because 1. There are a lot of similar questions that need to be looked into. 2. The question does not show attempts to do it yourself. 3. The question does not affect anything other than the framework, even painted on Wikipedia. 4. The question is of no value to anyone except the author. - Qwertiy ♦

  • Um .. The language is not the same ... - Qwertiy ♦

  • 1. Sometimes it happens. 2. The article mainly describes the work with regulars, methods and everything in this spirit. By syntax there is very little. It may be easier to look at Wikipedia and see the short label. - Qwertiy ♦
  • @Qwerty 1- did not come across, I agree. 2 - Just a sign from Wikipedia did not help me. Understood only after reading this article, although, your truth, perhaps it was the examples that most helped. - Ssssory
