( #3333=superdoc: print w/replies, xml ) Need Help??

I've been doing a lot of work with Mojolicious lately and I've been liking it. It provides Mojo::IOLoop::Subprocess to fork off a subprocess so that one doesn't block the server.

#!/usr/bin/env perl use Mojolicious::Lite -signatures; use Mojo::IOLoop; get '/' => sub ($c) { $c->render(template => 'index'); } => 'index'; post '/doit' => sub ($c) { $c->render_later; Mojo::IOLoop->subprocess->run_p(sub { # this code is actually running in a subprocess! sleep 10; return "I did the thing!"; })->then(sub (@results) { $c->render(text => "@results"); })->catch(sub ($err) { $c->reply->exception($err); }); } => 'doit'; app->start; __DATA__ @@ index.html.ep % layout 'main', title => 'Hello, World!'; <div> %= form_for doit => ( method=>'post' ) => begin %= submit_button 'Do the thing' %= end </div> @@ layouts/main.html.ep <!DOCTYPE html> <html> <head><title><%= title %></title></head> <body> %= content </body> </html>

You could combine this with e.g. aychnronous AJAX form submission like I showed here, or one could probably even send progress messages (a feature provided by Mojo::IOLoop::Subprocess) to the browser using something like Javascript's EventSource API, which I included an example of here.

Update 2022-04-07: I've now posted an example of just that here.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
