comments

问题 I (sort of) already know the answer to this question. But I figured it is one that gets asked so frequently on the R Users list, that there should be one solid good answer. To the best of my knowledge there is no multiline comment functionality in R. So, does anyone have any good workarounds? While quite a bit of work in R usually involves interactive sessions (which casts doubt on the need for multiline comments), there are times when I've had to send scripts to colleagues and classmates,

问题 I would like to remove all HTML comments from my facelets before delivering to end users. Does any standard approach exist? 回答1: There are actually two ways: To remove ALL comments, add this to web.xml : <context-param> <param-name>javax.faces.FACELETS_SKIP_COMMENTS</param-name> <param-value>true</param-value> </context-param> or when you're still on JSF 1.2 which doesn't use Facelets as default view technology yet: <context-param> <param-name>facelets.SKIP_COMMENTS</param-name> <param-value

问题 Processing CSV files with csv.DictReader is great - but I have CSV files with comment lines in (indicated by a hash at the start of a line), for example: # step size=1.61853 val0,val1,val2,hybridisation,temp,smattr 0.206895,0.797923,0.202077,0.631199,0.368801,0.311052,0.688948,0.597237,0.402763 -169.32,1,1.61853,2.04069e-92,1,0.000906546,0.999093,0.241356,0.758644,0.202382 # adaptation finished The csv module doesn't include any way to skip such lines. I could easily do something hacky, but I

问题 Is there a plugin or tool in IntelliJ that will strip all comments out of your source .java files? I've read about an ANT task that can do this.. was looking to do the same from within the IDE. Alternatively a TextPad plugin would work as well.. 回答1: You can use the "Replace" (or "Replace in Path" if you want to remove comments in multiple files) in the regular expression mode and then use this regular expression in the "Text to find" field: (/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/|[ \t]*//

问题 This question was asked four years ago, but the answer is now out of date for BS4. I want to delete all comments in my html file using beautiful soup. Since BS4 makes each comment as a special type of navigable string, I thought this code would work: for comments in soup.find_all('comment'): comments.decompose() So that didn't work.... How do I find all comments using BS4? 回答1: You can pass a function to find_all() to help it check whether the string is a Comment. For example I have below

问题 I'm using <!--[if IE 8]><![endif]--> for targeting IE8, but there's some JS that I want to load for all browsers EXCEPT IE8, what conditional comment should I use? Edit: I wonder if this would work: <!--[if lte IE 8]><![endif]--> Thanks 回答1: I can think of a trick. Set a variable inside the IE conditional tag and include your JS code if that variable isn't set. <script> var ie8 = false; </script> <!--[if IE 8]> <script> ie8 = true; </script> <![endif]--> <script> if (ie8 == false) { // any

问题 How do I comment out a block of tags in XML? I.e. How can I comment out <staticText> and everything inside it, in the code below? <detail> <band height="20"> <staticText> <reportElement x="180" y="0" width="200" height="20"/> <text><![CDATA[Hello World!]]></text> </staticText> </band> </detail> I could use <!-- staticText--> but that's just for single tags (as what I know), like // in Java and C. I would like something more like how /** comment **/ can be used in Java and C, so I can comment

问题 I need to remove all JavaScript comments from a JavaScript source using the JavaScript RegExp object. What I need is the pattern for the RegExp. So far, I've found this: compressed = compressed.replace(/\/\*.+?\*\/|\/\/.*(?=[\n\r])/g, ''); This pattern works OK for: /* I'm a comment */ or for: /* * I'm a comment aswell */ But doesn't seem to work for the inline: // I'm an inline comment I'm not quite an expert for RegEx and it's patterns, so I need help. Also, I' would like to have a RegEx
