How do I reference a C# keyword in XML documentation?

Extract keyphrases from text (1-4 word ngrams)

由 早过忘川 提交于 2019-12-03 04:35:21
问题 What's the best way to extract keyphrases from a block of text? I'm writing a tool to do keyword extraction: something like this. I've found a few libraries for Python and Perl to extract n-grams, but I'm writing this in Node so I need a JavaScript solution. If there aren't any existing JavaScript libraries, could someone explain how to do this so I can just write it myself? 回答1: I like the idea, so I've implemented it: See below (descriptive comments are included).

Do C# static functions perform better than nonstatic functions, beyond reduced memory usage?

由 白昼怎懂夜的黑 提交于 2019-12-03 03:29:23
问题 I assume that public or private static targets must have reduced memory usage, due to the fact that there is only one copy of the static target in memory. It seems like because a method is static that might make the method a potential point for further optimization by the CLR compiler beyond what is possible with a non-static function. Just a flimsy theory though, so I've come to ask you all. Do static public or private methods provide any increased performance benefit beyond reduced memory

How does const after a function optimize the program?

由 ぃ、小莉子 提交于 2019-12-03 03:21:39
问题 I've seen some methods like this: void SomeClass::someMethod() const; What does this const declaration do, and how can it help optimize a program? Edit I see that the first part of this question has been asked before... BUT , it still doesn't answer the second part: how would this optimize the program? 回答1: If the compiler knows that the fields of a class instance are not modified across a const member function call, it doesn't have to reload any fields that it may have kept in registers

`final` keyword equivalent for variables in Python?

由 拈花ヽ惹草 提交于 2019-12-03 02:57:14
问题 I couldn't find documentation on an equivalent of Java's final in Python, is there such a thing? I'm creating a snapshot of an object (used for restoration if anything fails); once this backup variable is assigned, it should not be modified -- a final-like feature in Python would be nice for this. 回答1: Having a variable in Java be final basically means that once you assign to a variable, you may not reassign that variable to point to another object. It actually doesn't mean that the object

inline vs __inline vs __inline__ vs __forceinline?

由 …衆ロ難τιáo~ 提交于 2019-12-03 01:34:03
问题 What are the differences between these four inline (key)words? inline , __inline , __inline__ , __forceinline . 回答1: inline is the keyword, in C++ and C99. __inline is a vendor-specific keyword (e.g. MSVC) for inline function in C, since C89 doesn't have it. __inline__ is similar to __inline but is from another set of compilers. __forceinline is another vendor-specific (mainly MSVC) keyword, which will apply more force to inline the function than the __inline hint (e.g. inline even if it

Keyword analysis in PHP

由 泪湿孤枕 提交于 2019-12-03 01:13:43
问题 For a web application I'm building I need to analyze a website, retrieve and rank it's most important keywords and display those. Getting all words, their density and displaying those is relatively simple, but this gives very skewed results (e.g. stopwords ranking very high). Basically, my question is: How can I create a keyword analysis tool in PHP which results in a list correctly ordered by word importance? 回答1: Recently, I've been working on this myself, and I'll try to explain what I did

extern keyword usage

由 荒凉一梦 提交于 2019-12-02 22:13:22
I have three programs in which I am using extern keyword. I am not able to understand the result. Below are three examples: Example 1: I was expecting that below code will give compilation error that multiple declaration of k . But it works fine? int k; //works fine extern int k = 10; void main() { cout<<k<<endl; getchar(); } Example 2: When I am trying to initialize "k" in above example compiler gives error. Why? int k = 20; //error extern int k = 10; void main() { cout<<k<<endl; getchar(); } Example 3: In this example I changed the order of definitions mentioned in example 1. When I compile

Keyword extraction software [closed]

Closed. This question is off-topic. It is not currently accepting answers. Learn more . Want to improve this question? Update the question so it's on-topic for Stack Overflow. I am looking for a piece of software that, given some text, will extract the "meaningful" keywords. For example, in the sentence: StackExchange is an online community. I want "StackExchange" and "online community" to be singled out as semantically-meaningful keywords, but not "is" or "an". A bit of research led to Alchemy API , which does the job well. Are there other solutions out there, especially open source ones?

Bare words / new keywords in Python

由 狂风中的少年 提交于 2019-12-02 20:38:59
I wanted to see if it was possible to define new keywords or, as they're called in WAT's Destroy All Software talk when discussing Ruby, bare words, in Python. I came up with an answer that I couldn't find elsewhere, so I decided to share it Q&A style on StackOverflow. I've only tried this in the REPL, outside any block, so far. It may be possible to make it work elsewhere, too. I put this in my python startup file: def bareWordHandler(type_, value, traceback_): if isinstance(value, SyntaxError): import traceback # You can probably modify this next line so that it'll work within blocks, as
