NAME

Imager::APIRef - Imager's C API - reference.

SYNOPSIS

i_color color;
color.rgba.r = 255; color.rgba.g = 0; color.rgba.b = 255;
double x[] = { ... };
double y[] = { ... };
i_polygon_t poly;
poly.count = sizeof(x) / sizeof(*x);
poly.x = x;
poly.y = y;

EOS

for my $cat (sort { lc $a cmp lc $b } keys %cats) { print OUT "\n # $cat\n"; my @funcs = @{$cats{$cat}}; my %orig; @orig{@funcs} = 0 .. $#funcs; @funcs = sort { $order{$a} <=> $order{$b} || $orig{$a} <=> $orig{$b} } @funcs; for my $func (grep $funcsyns{$_}, @funcs) { my $syn = $funcsyns{$func}; $syn =~ s/^/ /gm; print OUT $syn; } }

print OUT <<'EOS';

DESCRIPTION

EOS

my %undoc = %funcs;

for my $cat (sort { lc $a cmp lc $b } keys %cats) { print OUT "=head2 $cat\n\n=over\n\n"; my @ordered_funcs = sort { $order{$a} <=> $order{$b} || lc $a cmp lc $b } @{$cats{$cat}}; for my $func (@ordered_funcs) { print OUT @{$alldocs{$func}}, "\n"; print OUT "=for comment\nFrom: $from{$func}\n\n"; delete $undoc{$func}; } print OUT "\n=back\n\n"; }

# see if we have an uncategorised section if (grep $alldocs{$_}, keys %undoc) { print OUT "=head2 Uncategorized functions\n\n=over\n\n"; #print join(",", grep !exists $order{$_}, @funcs), "\n"; for my $func (sort { $order{$a} <=> $order{$b} || $a cmp $b } grep $undoc{$_} && $alldocs{$_}, @funcs) { print OUT @{$alldocs{$func}}, "\n"; print OUT "=for comment\nFrom: $from{$func}\n\n"; delete $undoc{$func}; } print OUT "\n\n=back\n\n"; }

if (keys %undoc) { print OUT <<'EOS';

UNDOCUMENTED

The following API functions are undocumented so far, hopefully this will change:

EOS

print OUT "=item *\n\nB<$_>\n\n" for sort keys %undoc;

print OUT "\n\n=back\n\n";
}

print OUT <<'EOS';

NAME

apidocs.perl - parse Imager's source for POD documenting the C API

SYNOPSIS

perl apidocs.perl lib/Imager/APIRef.pod

DESCRIPTION

Parses Imager's C sources, including .c, .h and .im files searching for function documentation.

Besides the normal POD markup, the following can be included:

=category category-name

The category the function should be in.

=synopsis sample-code

Sample code using the function to include in the Imager::APIRef SYNOPSIS

=order integer

Allows a function to be listed out of order. If this isn't specified it defaults to 50, so a value of 10 will cause the function to be listed at the beginning of its category, or 90 to list at the end.

Functions with equal order are otherwise ordered by name.
