OverviewGiven a language, it defines a representation of its syntax and an interpreter that uses this representation to interpret sentences in the language.ApplicabilityWhen a language needs to be interpreted and executed, and you can represent sentences in the language as an abstract syntax tree, you can use the interpreter mode. This mode works best in the following situations:This grammar is simple for c

Talk about my own background, I am a dabbler programmer, do anything like to know more and try again, I have been exposed to many languages, most of them as tools to useMost of my work now lies in data mining and machine learning, and web development, and the first language I've worked with is Python, where I learned about the concept of functional programming.Speaking of Lisp is said to be a copy of Lisp P

To learn Lisp, you can see SICP, I spent a summer time to chew SICP, chew to chew not move, but found that really learned a lot of interesting things, and then go to play Haskell, probably learn Haskell intermittent also have half a year of time, But I feel that what I learned in Haskell is much more than what I've learnt in SICP, probably because I'm not strong enough to understand the essence of SICP.Learning Haskell has taught me how wonderful it i

 The function required by the topic requires the following three things to be done: Write a function that accepts three numbers as a parameter Determine the larger of the three numbers in two Calculates the sum of squares of a larger two numbers (the sum of the squares of two numbers) We're going to do these three tasks from the back to the next step.CSDN No Lisp.

Structure Intention Given a language, define a representation of its grammar and define an interpreter that interprets the sentences in the language using that representation. Applicability You can use the interpreter pattern when there is a language that needs to be interpreted and executed, and you can represent a sentence in that language as an

2012Last semester, the Dian team of Emy of science and technology made me feel the industrial level for the first time.CodeAlthough I am still far away from these, I have been quite touched (here I mention a sister paper from huake, although I know that I am very, very watery,, I always told me that "senior students cheer for senior students", and finally I knew that I was actually a soy sauce, but I really appreciate her ). The seed cup has always been a partial research on underlying computer

PHP object-oriented interpreter mode, php object-oriented Interpreter I have been visiting the blog for more than a year. I have always read articles but have never published any articles. The main reason is that the technology is too good, and there is only a learning part, so there is nothing to share with you at that level. However, I recently read "going deep into PHP object-oriented models and practice
