Operating Systems OS X (Apple) MacOS 10.15 (Catalina) switches from bash to zsh Post 303040250 by Corona688 on Friday 25th of October 2019 11:32:34 AM
Old 10-25-2019
zsh is a really odd choice. It's a hodgepodge of features from bourne and csh, with its own special extensions. It's not comparable and not compatible.

I don't know why they needed a shell to be app-store compatible, but it probably isn't good. Perhaps they're ripping OSX apart and moving bits to the app store. It mMakes sense from a business point of view -- a good way to force everyone who's avoided the app store to use it. It makes sense from a software point of view -- why have two installer/updater systems?

NAME
Mojo - Duct tape for the HTML5 web! SYNOPSIS
use Mojo::Base 'Mojo'; # All the complexities of CGI, PSGI, HTTP and WebSockets get reduced to a # single method call! sub handler { my ($self, $tx) = @_; # Request my $method = $tx->req->method; my $path = $tx->req->url->path; # Response $tx->res->code(200); $tx->res->headers->content_type('text/plain'); $tx->res->body("$method request for $path!"); # Resume transaction $tx->resume; } DESCRIPTION
Mojo provides a flexible runtime environment for Perl real-time web frameworks. It provides all the basic tools and helpers needed to write simple web applications and higher level web frameworks such as Mojolicious. See Mojolicious for more! ATTRIBUTES
Mojo implements the following attributes. "home" my $home = $app->home; $app = $app->home(Mojo::Home->new); The home directory of your application, defaults to a Mojo::Home object which stringifies to the actual path. # Generate portable path relative to home directory my $path = $app->home->rel_file('data/important.txt'); "log" my $log = $app->log; $app = $app->log(Mojo::Log->new); The logging layer of your application, defaults to a Mojo::Log object. # Log debug message $app->log->debug('It works!'); "ua" my $ua = $app->ua; $app = $app->ua(Mojo::UserAgent->new); A full featured HTTP 1.1 user agent for use in your applications, defaults to a Mojo::UserAgent object. Note that this user agent should not be used in plugins, since non-blocking requests that are already in progress will interfere with new blocking ones. # Perform blocking request my $body = $app->ua->get('mojolicio.us')->res->body; METHODS
Mojo inherits all methods from Mojo::Base and implements the following new ones. "new" my $app = Mojo->new; Construct a new Mojo application. Will automatically detect your home directory and set up logging to "log/mojo.log" if there's a "log" directory. "build_tx" my $tx = $app->build_tx; Transaction builder, defaults to building a Mojo::Transaction::HTTP object. "config" my $config = $app->config; my $foo = $app->config('foo'); $app = $app->config({foo => 'bar'}); $app = $app->config(foo => 'bar'); Application configuration. # Manipulate configuration $app->config->{foo} = 'bar'; my $foo = $app->config->{foo}; delete $app->config->{foo}; "handler" $app->handler($tx); The handler is the main entry point to your application or framework and will be called for each new transaction, which will usually be a Mojo::Transaction::HTTP or Mojo::Transaction::WebSocket object. Meant to be overloaded in a subclass. sub handler { my ($self, $tx) = @_; ... } SEE ALSO
