NAME

Sub::Spec::To::HTML - Generate HTML documentation from sub spec

VERSION

version 0.003

SYNOPSIS

use Sub::Spec::To::HTML qw(spec_to_html);
my $html = spec_to_html(spec => $spec,
                        # other options
                       );

DESCRIPTION

EARLY RELEASE. NO IMPLEMENTATION YET!

This module can generate HTML document from sub spec.

This module uses Log::Any logging framework.

$pod .= "=head2 $sub_spec->{name}(\%args) -> ".
    ($naked ? "RESULT" : "[STATUS_CODE, ERR_MSG, RESULT]")."\n\n";

if ($sub_spec->{summary}) {
    $pod .= "$sub_spec->{summary}.\n\n";
}

my $desc = $sub_spec->{description};
if ($desc) {
    $desc =~ s/^\n+//; $desc =~ s/\n+$//;
    $pod .= "$desc\n\n";
}

if ($naked) {

} else {
    $pod .= <<'_';
Returns a 3-element arrayref. STATUS_CODE is 200 on success, or an error code
between 3xx-5xx (just like in HTTP). ERR_MSG is a string containing error
message, RESULT is the actual result.

_ }

my $features = $sub_spec->{features} // {};
if ($features->{reverse}) {
    $pod .= <<'_';
This function supports reverse operation. To reverse, add argument C<-reverse>
=> 1.

_ } if ($features->{undo}) { $pod .= <<'_'; This function supports undo operation. See Sub::Spec::Clause::features for details on how to perform do/undo/redo.

_ } if ($features->{dry_run}) { $pod .= <<'_'; This function supports dry-run (simulation) mode. To run in dry-run mode, add argument -dry_run => 1.

_ } if ($features->{pure}) { $pod .= <<'_'; This function is declared as pure, meaning it does not change any external state or have any side effects.
