Use perl CGI to create <a href="url" target="t">text</a>?

misterperl has asked for the wisdom of the Perl Monks concerning the following question:

Hello Beloved Monks:

I researched this , and the only answer I find is to abandon CGI.pm for this particular tag, and to just "print" the anchor. Even on perldoc.org:

...Something like this will do the trick.
$myself = self_url;
print "<a href=\"$myself#table1\">See table 1</a>";  <=== really?
[download]

I did find one site that implied there was a $cgi->a() method, but I found no documentation for it, nor how to close the tag with /a. One slashdot suggestion was to ^F for anchor on the CGI docs, and it came back RED. Is the practice truly to abandon CGI.pm for this requirement and instead print? I've become disciplined to use Perl CGI to generate all HTML , so this seems very unnatural.

Regards to all Monks!

HTML generating functions have been moved to CGI::HTML::Functions. `$cgi->a` isn't documented there, but the example right at the beginning of the linked section should be enough to understand how it works. Nowadays, we usually use templates to generate HTML (Template::Toolkit, Text::Xslate). Going back to `print` is not the right way. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]

Going back to print is not the right way. a template by any other name ;) since it started in ~1995 it didn't take a lot of work with "CGI::HTML::Functions" to find bugs, then check the bug cue/Changes, and realize bugs remain and reappear way too frequently to be relied upon, so you start writing your own functions and soon soon you turn it into heredocs with escapeHTML... There is a reason a diy templating engine is a rite of passage	[reply]

How do you think CGI generates HTML output if not by printing it? And the documentation itself uses print in several examples (explicitly printing anchors, in fact). It should take just a second to work out from the `_tag_func` sub in the code to work out that attributes for tag generation should be passed as a hashref followed by the contents. `$ perl -MCGI -E 'say CGI->new->a( {href => "http://example.com"}, "Sam +ple" )' <a href="http://example.com">Sample</a>` [download] That being said in general it'd be better practice to use a templating engine for your HTML generation with that taking any dynamic values from whatever context its passed. If you look at Mojolicious and the like (Dancer2 (?), edit Dancer2::Template::TemplateToolkit specifically maybe) those use that kind of approach typically. The cake is a lie. The cake is a lie. The cake is a lie.	[reply] [d/l] [select]

Thanks, my question wasn't how or if to print. It was about how or if to use $cgi->a() which was answered but TY.	[reply]

If, contrary to the advice you have been given you insist on using `CGI.pm`, then I recommend that you buy the a copy of the ancient companion book "A Complete Guide to Programming with CGI.pm" (ISBN 0471247448). Your current question is answered in "Chapter Two: CGI.pm Basics" Bill	[reply] [d/l]
