Re: [Mason] how to debug Mason code?

[Emil-Nicolaie P. <em...@gm...>]

start with https://www.perl.org/books/beginning-perl/, then to read
http://www.masonbook.com/

for Perl you have the perl debugger http://perldoc.perl.org/perldebug.html,
you can run tests scripts to debug your templates with it

HTML::Mason is compiled into Perl code and ran on the backend and the
output, including the js code is sent to the browser; the javascript runs
in the browser: you can't debug them in the same time
