NAME
    SHARYANTO::String::Util - String utilities

FUNCTIONS
  trim_blank_lines($str) => STR
    Trim blank lines at the beginning and the end. Won't trim blank lines in
    the middle. Blank lines include lines with only whitespaces in them.

  ellipsis($str[, $maxlen, $ellipsis]) => STR
    Return $str unmodified if $str's length is less than $maxlen (default
    80). Otherwise cut $str to ($maxlen - length($ellipsis)) and append
    $ellipsis (default '...') at the end.

  indent($indent, $str, \%opts) => STR
    Indent every line in $str with $indent. Example:

     indent('  ', "one\ntwo\nthree") # "  one\n  two\n  three"

    %opts is optional. Known options:

    *   indent_blank_lines => BOOL (default 1)

        If set to false, does not indent blank lines (i.e., lines containing
        only zero or more whitespaces).

  linenum($str, \%opts) => STR
    Add line numbers. For example:

         1|line1
         2|line2
          |
         4|line4

    Known options:

    *   width => INT (default: 4)

    *   zeropad => BOOL (default: 0)

        If turned on, will output something like:

          0001|line1
          0002|line2
              |
          0004|line4

    *   skip_empty => BOOL (default: 1)

        If set to false, keep printing line number even if line is empty:

             1|line1
             2|line2
             3|
             4|line4

  pad($text, $width[, $which[, $padchar[, $truncate]]]) => STR
    Return $text padded with $padchar to $width columns. $which is either
    "r" or "right" for padding on the right (the default if not specified),
    "l" or "left" for padding on the right, or "c" or "center" or "centre"
    for left+right padding to center the text.

    $padchar is whitespace if not specified. It should be string having the
    width of 1 column.

  qqquote($str) => STR
    Quote or encode $str to the Perl double quote ("qq") literal
    representation of the string. Example:

     say qqquote("a");        # => "a"
     say qqquote("a\n");      # => "a\n"
     say qqquote('"');        # => "\""
     say qqquote('$foo');     # => "\$foo"

    This code is taken from "quote()" in Data::Dump. Maybe I didn't look
    more closely, but I couldn't a module that provides a function to do
    something like this. String::Escape, for example, provides "qqbackslash"
    but it does not escape "$".
