阅读更多关于 Is there a way to escape a closing bracket for comments?

问题 I'm adding comments to my Delphi code for documentation. One of the things I'm trying to document is the JSON structure, so I'm trying to put sample JSON data commented in the code. However, JSON widely uses the squiggly brackets { } , which coincidentally is also used for comments in Delphi. Because of this, I can't figure out a way to add these comments. Usually for documentation comment blocks I use { } , for example: { This unit does this and that. Use TSomeComponent to do bla bla } When

问题 In Visual Studio, I have a block of code. I highlight it and use Ctrl+k+c to comment out the block. That adds "//" at the start of every line I highlighted. I then try to submit my code... and I run into StyleCop rule "SA1005" that requires all // to be followed by a space or be changed to ////. I would really like to modify Visual Studio so that ctrl+k+c adds "// ". I have not found any extensions or options that make that happen.

Do comments make the code run slower?

阅读更多关于 Do comments make the code run slower?

问题 I heard that a heavily commented script runs slightly slower than a non-commented one. Is it true? Did anyone test this? (like how much slower is it in percentages) 回答1: Commenting will not affect the script execution time in normal case. But the number of lines you write in your code affect the parser to read and buffer it considerably. If you can execute certain things in 20 lines, you try to write the same thing in 1000 lines, the performance might be affecting if its part of an

阅读更多关于 Team Foundation Server CheckIn Comment Template

I want to be able to provide a default comment template when developers check in items into TFS. e.g. "Description: Code Reviewer: Incident #: " I know there's a policy with Power Tools that checks if any text has been entered at all, but I'd like some predefined text to be presented ready for the developer to fill in the rest. I know there's also a 'Check-in Notes' section, but I'm trying to avoid this to make the process as streamlined as possible. The comments are also the first thing a user sees in the history list. That's why I want to use the comments box over the other options that are
