efa - unofficial efa.vrr.de command line client SYNOPSIS
efa --from city stop --to city stop [ additional options ] efa [ options ] from-city from-stop [ via-city via-stop ] to-city to-stop VERSION
version 2.01 DESCRIPTION
efa is a command line client for the <http://efa.vrr.de> web interface. It sends the specified information to the online form and displays the results. It should be noted that efa, although using the web interface of a local transport association, is able to look up connections all over Germany. OPTIONS
--from city stop Departure place --to city stop Arrival place --via city stop Travel via this place In case you want stop to be an address or "point of interest", you can set it to 'addr:something' or 'poi:something'. -t|--time|--depart hh:mm Journey start time -a|--arrive hh:mm Journey end time (overrides --time/--depart) -d|--date dd.mm.[yyyy] Journey date -b|--bike Choose connections allowing to carry a bike -e|--exclude transports Exclude transports (comma separated list). Possible transports: zug, s-bahn, u-bahn, stadtbahn, tram, stadtbus, regionalbus, schnellbus, seilbahn, schiff, ast, sonstige -E|--extended-info Display duration, ticket class and price for each route (if available) -m|--max-change number Print connections with at most number interchanges -P|--prefer type Prefer connections of type: o speed (default) The faster, the better o nowait Prefer connections with less interchanges o nowalk Prefer connections with less walking (at interchanges) -p|--proximity Take stops close to the stop/start into account and possibly use them instead -i|--include type Include connections using trains of type type, where type may be: o local (default) only take local trains ("Verbund-/Nahverkehrslinien"). Slow, but the cheapest method if you're not travelling long distance o ic Local trains + IC o ice All trains (local + IC + ICE) -w|--walk-speed speed Set your walking speed to speed. Accepted values: normal (default), fast, slow -I|--ignore-info [ regex ] Ignore additional information matching regex (default: /Fahrradmitnahme/) If regex is not supplied, removes the default regex (-> nothing will be ignored) --timeout seconds Set timeout for HTTP requests. Default: 60 seconds. --post key=value Add key with value to the HTTP POST request sent to the EFA server. This can be used to use setting efa does not yet cover, like "--post lineRestriction=400" to also show IC and ICE trains. Note that --post will be overridden by the standard efa options, such as --time -v|--version Print version information EXIT STATUS

Mojo::IOLoop(3pm) User Contributed Perl Documentation Mojo::IOLoop(3pm) NAME
Mojo::IOLoop - Minimalistic reactor for non-blocking TCP clients and servers SYNOPSIS
use Mojo::IOLoop; # Listen on port 3000 Mojo::IOLoop->server({port => 3000} => sub { my ($loop, $stream) = @_; $stream->on(read => sub { my ($stream, $chunk) = @_; # Process input say $chunk; # Got some data, time to write $stream->write('HTTP/1.1 200 OK'); }); }); # Connect to port 3000 my $id = Mojo::IOLoop->client({port => 3000} => sub { my ($loop, $err, $stream) = @_; $stream->on(read => sub { my ($stream, $chunk) = @_; # Process input say "Input: $chunk"; }); # Write request $stream->write("GET / HTTP/1.1 "); }); # Add a timer Mojo::IOLoop->timer(5 => sub { my $loop = shift; $loop->remove($id); }); # Start loop if necessary Mojo::IOLoop->start unless Mojo::IOLoop->is_running; DESCRIPTION
Mojo::IOLoop is a very minimalistic reactor based on Mojo::Reactor, it has been reduced to the absolute minimal feature set required to build solid and scalable non-blocking TCP clients and servers. Optional modules EV, IO::Socket::INET6 and IO::Socket::SSL are supported transparently and used if installed. Individual features can also be disabled with the "MOJO_NO_IPV6" and "MOJO_NO_TLS" environment variables. A TLS certificate and key are also built right in to make writing test servers as easy as possible. Also note that for convenience the "PIPE" signal will be set to "IGNORE" when Mojo::IOLoop is loaded. See Mojolicious::Guides::Cookbook for more. ATTRIBUTES
Mojo::IOLoop implements the following attributes. "client_class" my $class = $loop->client_class; $loop = $loop->client_class('Mojo::IOLoop::Client'); Class to be used for opening TCP connections with the "client" method, defaults to Mojo::IOLoop::Client. "lock" my $cb = $loop->lock; $loop = $loop->lock(sub {...}); A callback for acquiring the accept mutex, used to sync multiple server processes. The callback should return true or false. Note that exceptions in this callback are not captured. $loop->lock(sub { my ($loop, $blocking) = @_; # Got the accept mutex, start listening return 1; }); "max_accepts" my $max = $loop->max_accepts; $loop = $loop->max_accepts(1000); The maximum number of connections this loop is allowed to accept before shutting down gracefully without interrupting existing connections, defaults to 0. Setting the value to 0 will allow this loop to accept new connections indefinitely. "max_connections" my $max = $loop->max_connections; $loop = $loop->max_connections(1000); The maximum number of parallel connections this loop is allowed to handle before stopping to accept new incoming connections, defaults to 1000. Setting the value to 0 will make this loop stop accepting new connections and allow it to shut down gracefully without interrupting existing connections. "reactor" my $reactor = $loop->reactor; $loop = $loop->reactor(Mojo::Reactor->new); Low level event reactor, usually a Mojo::Reactor::Poll or Mojo::Reactor::EV object. # Watch handle for I/O events $loop->reactor->io($handle => sub { my ($reactor, $writable) = @_; say $writable ? 'Handle is writable' : 'Handle is readable'; }); "server_class" my $class = $loop->server_class; $loop = $loop->server_class('Mojo::IOLoop::Server'); Class to be used for accepting TCP connections with the "server" method, defaults to Mojo::IOLoop::Server. "stream_class" my $class = $loop->stream_class; $loop = $loop->stream_class('Mojo::IOLoop::Stream'); Class to be used by "client" and "server" methods for I/O streams, defaults to Mojo::IOLoop::Stream. "unlock" my $cb = $loop->unlock; $loop = $loop->unlock(sub {...}); A callback for releasing the accept mutex, used to sync multiple server processes. Note that exceptions in this callback are not captured. METHODS
Mojo::IOLoop inherits all methods from Mojo::Base and implements the following new ones. "client" my $id = Mojo::IOLoop->client(address => '127.0.0.1', port => 3000, sub {...}); my $id = $loop->client(address => '127.0.0.1', port => 3000, sub {...}); my $id = $loop->client({address => '127.0.0.1', port => 3000}, sub {...}); Open TCP connection with "client_class", which is usually Mojo::IOLoop::Client, takes the same arguments as "connect" in Mojo::IOLoop::Client. # Connect to localhost on port 3000 Mojo::IOLoop->client({port => 3000} => sub { my ($loop, $err, $stream) = @_; ... }); "delay" my $delay = Mojo::IOLoop->delay; my $delay = $loop->delay; my $delay = $loop->delay(sub {...}); Get Mojo::IOLoop::Delay object to synchronize events and subscribe to event "finish" in Mojo::IOLoop::Delay if optional callback is provided. # Synchronize multiple events my $delay = Mojo::IOLoop->delay(sub { say 'BOOM!' }); for my $i (1 .. 10) { $delay->begin; Mojo::IOLoop->timer($i => sub { say 10 - $i; $delay->end; }); } # Wait for events if necessary $delay->wait unless Mojo::IOLoop->is_running; "generate_port" my $port = Mojo::IOLoop->generate_port; my $port = $loop->generate_port; Find a free TCP port, this is a utility function primarily used for tests. "is_running" my $success = Mojo::IOLoop->is_running; my $success = $loop->is_running; Check if loop is running. exit unless Mojo::IOLoop->is_running; "one_tick" Mojo::IOLoop->one_tick; $loop->one_tick; Run reactor until an event occurs or no events are being watched anymore. Note that this method can recurse back into the reactor, so you need to be careful. "recurring" my $id = Mojo::IOLoop->recurring(0 => sub {...}); my $id = $loop->recurring(3 => sub {...}); Create a new recurring timer, invoking the callback repeatedly after a given amount of time in seconds. # Invoke as soon as possible Mojo::IOLoop->recurring(0 => sub { say 'Reactor tick.' }); "remove" Mojo::IOLoop->remove($id); $loop->remove($id); Remove anything with an id, connections will be dropped gracefully by allowing them to finish writing all data in their write buffers. "server" my $id = Mojo::IOLoop->server(port => 3000, sub {...}); my $id = $loop->server(port => 3000, sub {...}); my $id = $loop->server({port => 3000}, sub {...}); Accept TCP connections with "server_class", which is usually Mojo::IOLoop::Server, takes the same arguments as "listen" in Mojo::IOLoop::Server. # Listen on port 3000 Mojo::IOLoop->server({port => 3000} => sub { my ($loop, $stream, $id) = @_; ... }); "singleton" my $loop = Mojo::IOLoop->singleton; The global Mojo::IOLoop singleton, used to access a single shared loop object from everywhere inside the process. # Many methods also allow you to take shortcuts Mojo::IOLoop->timer(2 => sub { Mojo::IOLoop->stop }); Mojo::IOLoop->start; "start" Mojo::IOLoop->start; $loop->start; Start the loop, this will block until "stop" is called or no events are being watched anymore. # Start loop only if it is not running already Mojo::IOLoop->start unless Mojo::IOLoop->is_running; "stop" Mojo::IOLoop->stop; $loop->stop; Stop the loop, this will not interrupt any existing connections and the loop can be restarted by running "start" again. "stream" my $stream = Mojo::IOLoop->stream($id); my $stream = $loop->stream($id); my $id = $loop->stream($stream); Get Mojo::IOLoop::Stream object for id or turn object into a connection. # Increase inactivity timeout for connection to 300 seconds Mojo::IOLoop->stream($id)->timeout(300); "timer" my $id = Mojo::IOLoop->timer(5 => sub {...}); my $id = $loop->timer(5 => sub {...}); my $id = $loop->timer(0.25 => sub {...}); Create a new timer, invoking the callback after a given amount of time in seconds. # Invoke as soon as possible Mojo::IOLoop->timer(0 => sub { say 'Next tick.' }); DEBUGGING
You can set the "MOJO_IOLOOP_DEBUG" environment variable to get some advanced diagnostics information printed to "STDERR". MOJO_IOLOOP_DEBUG=1 SEE ALSO
