There are several ways to prevent line breaks in content. Using is one way, and works fine between words, but using it between an empty element and some text does not have a well-defined effect. The same would apply to the more logical and more accessible approach where you use an image for an … Read more
Like this: yourString = yourString.replaceAll(“\\s+”, ” “); For example System.out.println(“lorem ipsum dolor \n sit.”.replaceAll(“\\s+”, ” “)); outputs lorem ipsum dolor sit. What does that \s+ mean? \s+ is a regular expression. \s matches a space, tab, new line, carriage return, form feed or vertical tab, and + says “one or more of those”. Thus the … Read more
Shortest solution I can think of: if (string.trim().length() > 0) … This only checks for (non) white space. If you want to check for particular character classes, you need to use the mighty match() with a regexp such as: if (string.matches(“.*\\w.*”)) … …which checks for at least one (ASCII) alphanumeric character.
Instead of checking the entire string to see if there’s only whitespace, just check to see if there’s at least one character of non whitespace: if (/\S/.test(myString)) { // string is not empty and not just whitespace }
there are many ways, but here’s a simple, easy to understand way. add these lines to your ~/.vimrc: autocmd FileType html setlocal ts=2 sts=2 sw=2 autocmd FileType ruby setlocal ts=2 sts=2 sw=2 autocmd FileType javascript setlocal ts=4 sts=4 sw=4
In v2, there isn’t anything built-in for that much vertical space, so you’ll want to stick with a custom class. For smaller heights, I usually just throw a <div class=”control-group”> around a button.
Another option is if (myString?.trim()) { … } (using Groovy Truth for Strings)
People (and especially beginners) should never use scanf(“%s”) or gets() or any other functions that do not have buffer overflow protection, unless you know for certain that the input will always be of a specific format (and perhaps not even then). Remember than scanf stands for “scan formatted” and there’s precious little less formatted than … Read more

With with Git 2.11 (Q4 2016) and after, you can do: git config diff.wsErrorHighlight all See doc on git diff and on git config. For versions older than that, you can set the color.diff.whitespace config setting, e.g. with: git config color.diff.whitespace “red reverse” (I’m assuming that you already have color.diff or color.ui set to auto … Read more
