NAME ^

SHARYANTO::String::Util - String utilities

DESCRIPTION ^

FUNCTIONS ^

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:

linenum($str, \%opts) => STR

Add line numbers. For example:

     1|line1
     2|line2
      |
     4|line4

Known options:

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.
