ltrim($str) => STR¶

Trim whitespaces (including newlines) at the beginning of string. Equivalent to:

 $str =~ s/\A\s+//s;

ltrim_lines($str) => STR¶

Trim whitespaces (not including newlines) at the beginning of each line of string. Equivalent to:

 $str =~ s/^\s+//mg;

rtrim($str) => STR¶

Trim whitespaces (including newlines) at the end of string. Equivalent to:

 $str =~ s/[ \t]+\z//s;

rtrim_lines($str) => STR¶

Trim whitespaces (not including newlines) at the end of each line of string. Equivalent to:

 $str =~ s/[ \t]+$//mg;

trim($str) => STR¶

ltrim + rtrim.

trim_lines($str) => STR¶

ltrim_lines + rtrim_lines.

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 "$".

None are exported by default, but they are exportable.
