NAME

Term::Emit::Format::HTML - Formats Term::Emit output into HTML

VERSION

This document describes Term::Emit::Format::HTML version 0.0.2

SYNOPSIS

    use Term::Emit::Format::HTML 'format_html';
    my $out = "some output from Term::Emit";
    my $html = format_html($out);

DESCRIPTION

This module reformats the output from an application that uses Term::Emit into a chunk of HTML, which you can embed in a web page.

This module is handy if you write Web UIs that wrap a command line utility and show the output from that utility on a web page.

Suppose you have a utility that produces this output:

    Quobalating all frizzles...
        We operate on only the first and
        second frizzles in this step.
      Merfubbing primary frizzle.......... [OK]
      Xylokineting secondary frizzle...... [WARN]
    Quobalating all frizzles.............. [DONE]

This module can parse that output and convert it into this:

    <h1 class="done">Quobalating all frizzles</h1>
      <p>We operate on only the first and second frizzles in this step.</p>
      <h2 class="ok">Merfubbing primary frizzle</h2>
      <h2 class="warn">Xylokineting secondary frizzle</h2>

Note how the steps that have completed with a status, such as [OK] or [DONE], get tagged in the resulting HTML with a class. This simple hook allows you to do some fancy CSS so you can associate images, colors, and so forth with the output to really spiff up your web page.

SUBROUTINES/METHODS

format_html ( STRING )

This function parses the given STRING and returns an HTML string. The input STRING is presumed to be the captured output of some other application that uses Term::Emit.

DIAGNOSTICS

None.

CONFIGURATION AND ENVIRONMENT

Term::Emit::Format::HTML requires no configuration files or environment variables.

DEPENDENCIES

None.

INCOMPATIBILITIES

None reported.

BUGS AND LIMITATIONS

This is ALPHA code! It is not yet complete, but it's working well enough for simple, non-demanding cases. Use at your own risk!

The heuristic this module uses is rather simple-minded, and relies upon indentation to figure out nesting depths. If you set the indentation -step to 0 in Term::Emit, then this module will not be able to properly parse the string, even with bullets enabled. I hope to make it smarter in a future release (so it can tell nesting depth from the bullets, too).

No bugs have been reported.
