Understanding strange Perl multiline comment mechanism

自闭症网瘾萝莉.ら 提交于 2019-12-19 05:16:55
问题 EDIT: Note to new Perl programmers : This mechanism should NOT be used for multiline comments! It has a flaw decreases readability. In this PerlMonks post on mechanisms to produce multiline comments in Perl, Abigail provided this one, that perplexes me: The problem with just using a here document is that it will issue a warning under '-w'. It's much better to use the little known << >> operator. <<q=~q>>; This is a multiline comment. q Running it through -M0=Deparse gives: " This is a

问题 Is there a way to insert a snippet for XML comments in javascript in Visual Studio 2010 with automatically generated parameters? If I type /// here... function foo(a, b){ ...it should change to this (depending on the parameters): function foo(a, b){ /// <summary>$cursorhere</summary> /// <param name="a" type="string">Param a</param> /// <param name="b" type="string">Param b</param> /// <returns type="function">Return function</returns> So it would be similar to the snippet generation if I'm

Parse comment line

问题 Given the following basic grammar I want to understand how I can handle comment lines. Missing is the handling of the <CR><LF> which usually terminates the comment line - the only exception is a last comment line before the EOF, e. g.: # comment abcd := 12 ; # comment eof without <CR><LF> grammar CommentLine1a; //========================================================== // Options //========================================================== //=================================================

Including comments in Java regular expressions

问题 I have some complex regular expressions which I need to comment for readability and maintenance. The Java spec is rather terse and I struggled for a long time getting this working. I finally caught my bug and will post it as an answer but I'd be grateful for any other advice on maintaining regexes As an example I want to comment the subcomponents (of patternS) in a simple name parser: String testTarget = "Waldorf T. Flywheel"; String patternS = "([A-Za-z]+)\\s+([A-Z]\\.)?\\s+([A-Za-z]+)";

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . I'm looking for some tool to remove cooments from Javascript sources. I was able to Google some, but none of them satisfied the following requirement: Everything else should be left as it is, in particular white space is not removed, BUT if a comment takes a whole line, the line is removed too . Shortly, I want to

How to write an inline-comment in Python

问题 Is there a method of ending single line comments in Python? Something like /* This is my comment */ some more code here... 回答1: No, there are no inline comments in Python. From the documentation: A comment starts with a hash character ( # ) that is not part of a string literal, and ends at the end of the physical line . A comment signifies the end of the logical line unless the implicit line joining rules are invoked. Comments are ignored by the syntax; they are not tokens. 回答2: Whitespace in

Using Rails polymorphism for nested comments

问题 I need to build a nested comments system in a Rails 3 application that allows for comments on many models (articles, posts, etc) and am debating rolling my own solution along the lines of this post.

I need to be able to add comments to multiple models I need to be able to add comments to comments, infinitely deep I need to be able to efficiently retrieve all

Mid-line comment in Python?

核能气质少年 提交于 2019-12-18 12:43:35
问题 I'm wondering if there is any way to comment out part of a line, like you can do in c++ with /*this*/ . The only comments I know about are # this which always goes to the end of the line and the """these""" ones, which do not work mid-line. Example use-case: using subprocess and need to temporarily comment out an argument -p 0 from the list: ['../some/guy', '-m', '10', '-p', '0', '-n', '100', '-f', '/dev/stdout'] It would be nice to have a keyboard shortcut to comment out a selection, at the

Multiple facebook comment boxes on a single page?

[亡魂溺海] 提交于 2019-12-18 12:35:10
问题 I have three products listed on a single page and I'm looking to add a small comment box to the side of each of the products, kind of like : https://www.facebook.com/SanukFootwear?ref=ts&sk=app_113298085356151. The main problem is, I can't seem to figure out how to add more than one comment box to the page. I tried using HTML5 and XFBML. The code I'm using now is : <html xmlns:fb="http://ogp.me/ns/fb#"> <script> (function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d
