Event::ExecFlow is a high level API for event-based execution flow control.

ABSTRACT

Event::ExecFlow provides a ligh level API for defining complex flow controls with asynchronous execution of external programs.

SYNOPSIS

use Event::ExecFlow;

my $job = Event::ExecFlow::Job::Group->new (
jobs => [
Event::ExecFlow::Job::Command->new (
name => "transcode",
title => "Transcoding DVD title to OGG",
command => "transcode -i /dev/dvd ...",
fetch_output => 1,
progress_max => 4711, # number of frames
progress_parser => sub {
my ($job, $buffer) = @_;
$job->set_progress_cnt($1) if $buffer =~ /[d+-(d+)]/;
#-- or simply write this:
#-- progress_parser => qr/[d+-(d+)]/,
},
),
Event::ExecFlow::Job::Code->new (
name => "checks",
title => "Do some checks",
depends_on => [ "transcode" ],
code => sub {
my ($job) = @_;
my $transcode = $job->get_group->get_job_by_name("transcode");
if ( $transcode->get_output !~ /.../ ) {
$job->set_error_message("XY check failed");
}
#-- this could be done easier as a post_callback added to
#-- the "transcode" job above, but its nevertheless a good
#-- example for the Code job type and shows how jobs can
#-- interfere with each other.
},
),
Event::ExecFlow::Job::Command->new (
title => "Muxing OGG file",
depends_on => [ "checks" ],
command => "ogmmerge ...",
no_progress => 1,
),
],
);

#-- this inherits from Event::ExecFlow::Frontend
my $frontend = Video::DVDRip::GUI::ExecFlow->new(...);
$frontend->start_job($job);

Event::ExecFlow offers a high level API to declare jobs, which mainly execute external commands, parse their output to get progress or other status information, triggers actions when the command has been finished etc. Such jobs can be chained together in a recursive fashion to fulfill rather complex tasks which consist of many jobs.

Additionally it defines an extensible API for communication with the frontend application, which may be a written using Gtk2, Tk or Qt or is a simple text console program.

In case of Gtk2 a custom widget for displaying an Event::ExecFlow job plan, including progress updates, is shipped with the Gtk2::Ex::FormFactory package.

cflowd is a flow analysis tool currently used for analyzing Ciscos NetFlow enabled switching method.

The current release (described below) includes the collections, storage, and basic analysis modules for cflowd and for arts++ libraries. This analysis package permits data collection and analysis by ISPs and network engineers in support of capacity planning, trends analysis, and characterization of workloads in a network service provider environment. Other areas where cflowd may prove useful are: tracking for Web hosting, accounting and billing, network planning and analysis, network monitoring, developing user profiles, data warehousing and mining, as well as security-related investigations.


cflowd is no longer supported by CAIDA. Instead, please consider the use of flow-tools, which will provide a toolset for working with NetFlow data. flow-tools can also be used (like cflowd) in conjunction with FlowScan, maintained by Dave Plonka at the University of Wisconsin, Madison.

KidBASIC is an easy to use version of BASIC designed to teach young children the basics of computer programming. KidBASIC is a strictly line-oriented language, which helps kids easily see how program flow-control works.
It has a built-in graphics mode which lets them draw pictures on screen in minutes, and a set of detailed, easy-to-follow tutorials that introduce programming concepts through fun exercises.
KidBASIC is licensed under the GNU public license, which means that its free to download, modify, and share.
Enhancements:
- This version fixes a number of outstanding bugs, adds internationalization support, and adds a number of menu options, including a fully functional edit menu.
