escaping

In my web app, the user can make blog posts. When I display the blog post, newlines aren't shown because I didn't replace the new lines with <br> tags. The problem is that I've turned autoescaping on in Jinja, so <br> tags are escaped. I don't want to temporarily disable autoescaping, I want to specifically allow <br> tags. How would I do this? I have another answer that I think is the best. Initially I was just displaying my variable post.content as-is, and the newlines weren't being preserved. None of the solutions here worked (well), and my pre solution was just a quick fix and had major

This question already has an answer here: Replacing single '\' with '\\' in Java 6 answers I am using Java for a while and come up with this problem: I use hard-coded paths in windows like "D:\Java-code\JavaProjects\workspace\eypros\src" The problem is that I need to escape the backslash character in order to use it with string. So I manually escape each backslash: "D:\\Java-code\\JavaProjects\\workspace\\eypros\\src" Is there a way to automatically take the unescaped path and return an escaped java string. I am thinking that maybe another container besides java string could do the trick (but

I want to build a simple regex that covers quoted strings, including any escaped quotes within them. For instance, "This is valid" "This is \" also \" valid" Obviously, something like "([^"]*)" does not work, because it matches up to the first escaped quote. What is the correct version? I suppose the answer would be the same for other escaped characters (by just replacing the respective character). By the way, I am aware of the "catch-all" regex "(.*?)" but I try to avoid it whenever possible, because, not surprisingly, it runs somewhat slower than a more specific one. The problem with all the

I am building an automation suite using Xcode 7 with swift. My app loads with the following Alert View: Allow "Light Alarm" to access your location while you use the app? When I record with UI Testing and click this alert I get the following code: app.alerts["Allow \U201cLight Alarm\U201c to access your location while you use the app?"] Note: The quotes has been replaced with \U201c However, when I try and compile I get the following error: "Invalid escape sequence in literal" Anyone know how to get round this? Martin R This seems to be a bug in Xcode when generating code during UI recording.

I wrote a piece of code to convert PHP's striplashes into valid Python [backslash] escapes: cleaned = stringwithslashes cleaned = cleaned.replace('\\n', '\n') cleaned = cleaned.replace('\\r', '\n') cleaned = cleaned.replace('\\', '') How can I condense it? Not totally sure this is what you want, but.. cleaned = stringwithslashes.decode('string_escape') It sounds like what you want could be reasonably efficiently handled through regular expressions: import re def stripslashes(s): r = re.sub(r"\\(n|r)", "\n", s) r = re.sub(r"\\", "", r) return r cleaned = stripslashes(stringwithslashes) You can

My database stores product information, and a lot of this is organised into lists. I load the data into Angular as $scope.post . For instance, $scope.post.size_description = '<li> Fits true to size. Take your normal size\r</li> <li> Slim-cut, mid-rise style</li> <li> Long in length, alter to fit</li> <li> Model wears an IT 48\r</li> <li> Model measures: waist size 32, height 6\'1"/ 185cm\r</li>'. When I try to load this data into my Angular app, it gets rendered as text (i.e. the <li> are not parsed). I understand this probably happens for security reasons, but is there any way around it? jzm
