JSON does not allow real line-breaks. You need to replace all the line breaks with \n. eg: “first line second line” can saved with: “first line\nsecond line” Note: for Python, this should be written as: “first line\\nsecond line” where \\ is for escaping the backslash, otherwise python will treat \n as the control character “new … Read more
%w(foo bar) is a shortcut for [“foo”, “bar”]. Meaning it’s a notation to write an array of strings separated by spaces instead of commas and without quotes around them. You can find a list of ways of writing literals in zenspider’s quickref.
What about this: string tabs = new string(‘\t’, n); Where n is the number of times you want to repeat the string. Or better: static string Tabs(int n) { return new string(‘\t’, n); }
In Python 3.x, the correct way to check if s is a string is isinstance(s, str) The bytes class isn’t considered a string type in Python 3. In Python 2.x, the correct check was isinstance(s, basestring) basestring is the abstract superclass of str and unicode. It can be used to test whether an object is … Read more
You can use Parameter Expansion to do this. If a is constant, the following parameter expansion performs substring extraction: b=${a:12:5} where 12 is the offset (zero-based) and 5 is the length If the underscores around the digits are the only ones in the input, you can strip off the prefix and suffix (respectively) in two … Read more
Like this: InputStream stream = new ByteArrayInputStream(exampleString.getBytes(StandardCharsets.UTF_8)); Note that this assumes that you want an InputStream that is a stream of bytes that represent your original string encoded as UTF-8. For versions of Java less than 7, replace StandardCharsets.UTF_8 with “UTF-8”.
As you’re dealing with an array of strings, you can simply use array_filter(), which conveniently handles all this for you: print_r(array_filter($linksArray)); Keep in mind that if no callback is supplied, all entries of array equal to FALSE (see converting to boolean) will be removed. So if you need to preserve elements that are i.e. exact … Read more
To answer this question specifically, two problems: $randstring is not in scope when you echo it. The characters are not getting concatenated together in the loop. Here’s a code snippet with the corrections: function generateRandomString($length = 10) { $characters=”0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ”; $charactersLength = strlen($characters); $randomString = ”; for ($i = 0; $i < $length; $i++) { $randomString … Read more
String.Format(“{0:n}”, 1234); // Output: 1,234.00 String.Format(“{0:n0}”, 9876); // No digits after the decimal point. Output: 9,876
