Re^4: appending to html at beginning ( use CGI for parsing cgi) by Limbomusic (Acolyte) on Feb 03, 2017 at 13:59 UTC
Hey :-) Wow Ok, Got a lot to learn.. Didnt know that Matts guestbook script was such risky business... (altho my webserver is very dear to me - its just a personal playground, and I take a backup often, besides - I think the hiawatha webserver should be pretty secure) - But wow - many interesting suggestions - "swapping" file content with a temp text file seems actually quite understandable - but then - wow - the idea with a separate text file just listing all the stories is also a gem - because then one could - have links to a html file with all the different $names of peoples stories - so instead of just all stories being listed - one could click on someones name and their story would come up, that would be very cool. Anonymous Monk: yeah, probably better to just start from scratch listing all the $variables - eh stupid question, why do you all put "my" in front of the scalars?	[reply]

stupid question, why do you all put "my" in front of the scalars? Not stupid at all - it is to limit the scope. This is a very important concept in computing generally and is not just limited to Perl. However, you could do an awful lot worse than read the canonical article by Dominus: Coping with Scoping which deals with the whole issue of variable declaration in Perl. It goes into more depth that you'll need just now but it won't steer you wrong.	[reply]

Hi Anonymous, cgi module is best for doing that Plack, Catalyst, Dancer2, Mojolicious, and more... (Update: As hippo pointed out, CGI::Minimal, CGI::Lite, or CGI::Simple) - versus - A module that is no longer recommended by its own documentation, and was removed from Perl's core. I didn't even say the module was summarily bad, just that it shouldn't be recommended for newcomers/new developments. You're using some strange definitions of "best" and "trolling" ;-P Regards, -- Hauke D	[reply]
Re^5: appending to html at beginning (don't use CGI) by Corion (Patriarch) on Feb 03, 2017 at 16:48 UTC
Please - Plack and all the frameworks building on it are a far conceptual step away from CGI programs. If you want people to switch away from hand-parsing CGI parameters, I think it's better to lead them the longer but easier way via CGI.pm than leading them to the cliff that are HTTP frameworks.

Re^6: appending to html at beginning (don't use CGI.pm) by hippo (Bishop) on Feb 03, 2017 at 17:17 UTC
I completely agree with this sentiment. Also, it is not the case that CGI.pm is the only pure CGI game in town. I would recommend one of the smaller modules which does not come with the baggage of HTML-generating code as a better place to start. Take your pick from: CGI::Minimal, CGI::Lite, CGI::Simple or even the old CGI::Thin. Any of these would be a gentler introduction than Plack and will be much faster to run in a traditional CGI environment (of which plenty still exist, BTW).	[reply]

Re^6: appending to html at beginning (don't use CGI) by haukex (Archbishop) on Feb 03, 2017 at 16:56 UTC
Hi Corion, the cliff that are HTTP frameworks I see your point, but I have to disagree that all of the alternatives to CGI are so much more "worse". If we are talking about full-blown Catalyst, Dancer2, or Mojolicious apps, then yes, I would tend to agree with you that they might be a little too powerful and the learning curve might be a bit too steep for a newcomer. However, IMO plain Plack and Mojolicious::Lite are quite approachable. If someone learns only one toolbox for writing server-side scripts, I personally don't think CGI should be it, but instead one of the two aforementioned modules. Regards, -- Hauke D	[reply]

Re^5: appending to html at beginning (CGI.pm) by Anonymous Monk on Feb 04, 2017 at 02:33 UTC
Plack, Catalyst, Dancer2, Mojolicious, and more... All of those run slower then CGI.pm under CGI -- thats because they do a lot more than parse CGI parameters, have more dependencies, have bigger APIs ... (Update: As hippo pointed out, CGI::Minimal, CGI::Lite, or CGI::Simple) A module that is no longer recommended by its own documentation, and was removed from Perl's core. I didn't even say the module was summarily bad, just that it shouldn't be recommended for newcomers/new developments. By that logic, why would you even mention those other CGI::... modules? They were never in the perl core and they're just lesser imitations of the CGI.pm module You're using some strange definitions of "best" and "trolling" ;-P Look, its nice you've got enthusiasm for participation, but you should avoid railing against things, esp by copy/paste, thats just trolling Code over propaganda	[reply]

Hi Anonymous, By that logic, why would you even mention those other CGI::... modules? Simply because they're not deprecated, and don't have substantial portions of their functionality declared unmaintained. I just mentioned the removal from the core to underline that. And just in case it isn't clear yet, I have nothing against CGI (the protocol / environment), the point I was making is that CGI.pm (the module) shouldn't be recommended to newcomers or new developments, and that there are better alternatives. they're just lesser imitations ... you should avoid railing against things Right. thats just trolling ... says the anonymous post with mild insults and no substantial evidence or arguments.
