Won't trim blank lines in the middle. Blank lines include lines with only whitespaces in them. .ie n .SS "ellipsis($str[, $maxlen, $ellipsis]) => \s-1STR\s0" .el .SS "ellipsis($str[, \f(CW$maxlen\fP, \f(CW$ellipsis\fP]) => \s-1STR\s0" .IX Subsection "ellipsis($str[, $maxlen, $ellipsis]) => STR" Return \f(CW$str\fR unmodified if \f(CW$str\fR's length is less than \f(CW$maxlen\fR (default 80). Otherwise cut \f(CW$str\fR to ($maxlen \- length($ellipsis)) and append \f(CW$ellipsis\fR (default '...') at the end. .ie n .SS "indent($indent, $str, \e%opts) => \s-1STR\s0" .el .SS "indent($indent, \f(CW$str\fP, \e%opts) => \s-1STR\s0" .IX Subsection "indent($indent, $str, %opts) => STR" Indent every line in \f(CW$str\fR with \f(CW$indent\fR.

It should be string having the width of 1 column. .SS "qqquote($str) => \s-1STR\s0" .IX Subsection "qqquote($str) => STR" Quote or encode \f(CW$str\fR to the Perl double quote (\f(CW\*(C`qq\*(C'\fR) literal representation of the string. Example: .PP .Vb 4 \& say qqquote("a"); # => "a" \& say qqquote("a\en"); # => "a\en" \& say qqquote(\*(Aq"\*(Aq); # => "\e"" \& say qqquote(\*(Aq$foo\*(Aq); # => "\e$foo" .Ve .PP This code is taken from \f(CW\*(C`quote()\*(C'\fR in Data::Dump. Maybe I didn't look more closely, but I couldn't a module that provides a function to do something like this. String::Escape, for example, provides \f(CW\*(C`qqbackslash\*(C'\fR but it does not escape \f(CW\*(C`$\*(C'\fR. .PP None are exported by default, but they are exportable. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\s-1SHARYANTO\s0 .SH "HOMEPAGE" .IX Header "HOMEPAGE" Please visit the project's homepage at . .SH "SOURCE" .IX Header "SOURCE" Source repository is at \s-1HASH\s0(0x353ed90). .SH "BUGS" .IX Header "BUGS" Please report any bugs or feature requests on the bugtracker website https://rt.cpan.org/Public/Dist/Display.html?Name=SHARYANTO\-String\-Util .PP When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature. .SH "AUTHOR" .IX Header "AUTHOR" Steven Haryanto .SH "COPYRIGHT AND LICENSE" .IX Header "COPYRIGHT AND LICENSE" This software is copyright (c) 2013 by Steven Haryanto. .PP This is free software; you can redistribute it and/or modify it under the same terms as the Perl 5 programming language system itself.
