For those tasks I use most of the time block selection. Put your cursor on the first # character, press CtrlV (or CtrlQ for gVim), and go down until the last commented line and press x, that will delete all the # characters vertically. For commenting a block of text is almost the same: First, … Read more
NOTE: Regex is not a lexer or a parser. If you have some weird edge case where you need some oddly nested comments parsed out of a string, use a parser. For the other 98% of the time this regex should work. I had pretty complex block comments going on with nested asterisks, slashes, etc. … Read more
Look closer at the stack trace. Here’s the relevant part: … org.apache.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:189) com.sun.faces.facelets.el.ELText$ELTextVariable.toString(ELText.java:217) com.sun.faces.facelets.el.ELText$ELTextComposite.toString(ELText.java:157) com.sun.faces.facelets.compiler.CommentInstruction.write(CommentInstruction.java:77) … It’s thus evaluating EL in a comment block (recognizable by CommentInstruction). A comment block is considered as template text. Facelets evaluates by default also EL #{} in template text. It’s like as if you’re writing <p>#{screenShotBean.takeScreenshot}</p> without any JSF … Read more
Run the following command on your source file: gcc -fpreprocessed -dD -E test.c Thanks to KennyTM for finding the right flags. Here’s the result for completeness: test.c: #define foo bar foo foo foo #ifdef foo #undef foo #define foo baz #endif foo foo /* comments? comments. */ // c++ style comments gcc -fpreprocessed -dD -E … Read more
This is how I do it. Essentially by using Bash’s backtick command substitution one can place these comments anywhere along a long command line even if it is split across lines. I have put the echo command in front of your example so that you can execute the example and see how it works: echo … Read more
tl;dr: REM is the documented and supported way to embed comments in batch files. :: is essentially a blank label that can never be jumped to, whereas REM is an actual command that just does nothing. In neither case (at least on Windows 7) does the presence of redirection operators cause a problem. However, :: … Read more
You can use triple-quoted strings. When they’re not a docstring (the first thing in a class/function/module), they are ignored. ”’ This is a multiline comment. ”’ (Make sure to indent the leading ”’ appropriately to avoid an IndentationError.) Guido van Rossum (creator of Python) tweeted this as a “pro tip”. However, Python’s style guide, PEP8, … Read more
I believe that all the previously proposed solutions (apart from those that require specific implementations) result in the comments being included in the output HTML, even if they are not displayed. If you want a comment that is strictly for yourself (readers of the converted document should not be able to see it, even with … Read more
I am particularly guilty of this, embedding non-constructive comments, code poetry and little jokes into most of my projects (although I usually have enough sense to remove anything directly offensive before releasing the code). Here’s one I’m particulary fond of, placed far, far down a poorly-designed ‘God Object’: /** * For the brave souls who … Read more
you don’t nullify line comments. what you want is to turn //var page_background_color=”red”; into /**/var page_background_color=”red”; and vv.
