The problem is twofold. First of all, Haskell is indentation sensitive, e.g. the following code isn’t valid: example = (a, b) where a = “Hello” b = “World” Both bindings need to be indented with the same number of spaces/tabs (see off-side rule). While it’s obvious in this case, it’s rather hidden in the following … Read more
Just style the content with white-space: pre-wrap;. div { white-space: pre-wrap; } <div> This is some text with some extra spacing and a few newlines along with some trailing spaces and five leading spaces thrown in for good measure </div>
Oh, you can really easy accomplish that with a single line of CSS: #parent_of_imgs { white-space-collapse: discard; } Disadvantage, you ask? No browser has implemented this extremely useful feature (think of inline blocks in general) yet. 🙁 What I did from time to time, although it’s ugly as the night is dark, is to use … Read more
The str.split() method without an argument splits on whitespace: >>> “many fancy word \nhello \thi”.split() [‘many’, ‘fancy’, ‘word’, ‘hello’, ‘hi’]
st.replaceAll(“\\s+”,””) removes all whitespaces and non-visible characters (e.g., tab, \n). st.replaceAll(“\\s+”,””) and st.replaceAll(“\\s”,””) produce the same result. The second regex is 20% faster than the first one, but as the number consecutive spaces increases, the first one performs better than the second one. Assign the value to a variable, if not used directly: st = … Read more
As of R 3.2.0 a new function was introduced for removing leading/trailing white spaces: trimws() See: Remove Leading/Trailing Whitespace
You’re seeing the space for descenders (the bits that hang off the bottom of ‘y’ and ‘p’) because img is an inline element by default. This removes the gap: .youtube-thumb img { display: block; }
How do I trim leading/trailing whitespace in a standard way?
Something in the lines of myString.split(“\\s+”); This groups all white spaces as a delimiter. So if I have the string: “Hello[space character][tab character]World” This should yield the strings “Hello” and “World” and omit the empty space between the [space] and the [tab]. As VonC pointed out, the backslash should be escaped, because Java would first … Read more
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
