Perhaps before joining the continuation, it is important to talk about the cost of doing it so much. After all, the results are the same with no continuation calculation. However, this is a series of interests, learning this knowledge should be entirely out of curiosity and fun ideas. That's why I'm not going to tell you. Through control continuation can achieve call-with-current-continuation and exception handling functions. Let me briefly describe how the

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

The article welcomes reprint, but when reprint, please keep this paragraph text, and put in the article top author: Lu Junyi (Cenalulu)This article original address: http://cenalulu.github.io/python/gil-in-python/ Gil is what The Gil is not a Python feature, it is a concept introduced when implementing the Python parser (CPython). Just like C + + is a set of language (syntax) standards, but can be compiled into executable code with different compilers. Well-known compilers such as Gcc,intel c++,

In Windows, the python 2.x interpreter and the 3.x interpreter coexist. Python2 and Python3 are incompatible. If you encounter a situation where you cannot upgrade to Python2 code or your colleagues stick to the Python2 camp, you must consider the coexistence of Python2 and Python3 in the system. Mac OS X and Linux do not have to consider this situation. Because these Unix-like operating systems will dire

Shell, commonly known as shell, refers to a command parser in a UNIX system. It is mainly used for user-system interaction. There are many types of shell

This article has two purposes: one is to describe a common method for implementing a computer language interpreter, and the other is to highlight how to use Python to implement a subset of the Lisp scheme. I refer to my interpreter as Lispy (lis.py). A few years ago, I introduced how to write a scheme interpreter using Java, and I also wrote a version using Commo

13. Editing and history of interactive inputSome versions of the Python interpreter support editing the current input line and history, similar to what you see in the Korn shell and the GNU Bash shell. This is implemented using the GNU ReadLine Library, which supports EMACS-style and VI-style editing. This library has its own documentation, which I don't repeat here , But the rationale is easy to explain.

One, Shell interpreterShell interpreter, the bridge between the user and the operating system kernelThe shell is between the operating system kernel and the user, is responsible for receiving the user input operation instruction (command), and runs and interprets, passes the action which needs to carry on to the operating system kernel and executesThe shell program acts as a "command interpreter" role in th
