I pushed out a consept code for a new BBcode engine. Its main function gives the developer controle over many parts of the BBcode tags through its placeholders with HTML template design. AUBBC2

One main reason why I posted this is to ask: Does this look easy to use?

Note: The add_tag() in alpha 3 doesnt work and Im sure a few other things.

Adding Tags
        $aubbc->add_tag(
          'tag' => 'Tag',               # Tag name:
          'type' => '#',                # Type number: tag style
          'function' => '',             # Function: subroutine to expa
+nd methods
          'message' => 'any',           # Message: of tag
          'extra' => '',                # Extra: of tag
          'markup' => '',               # Template: output
        );

Type number: Tag style
1 [tag]
2 [tag]message[/tag] or [tag=extra]message[/tag] or [tag attr=x...]message[/tag] or [tag=x attr=x...]message[/tag]
3 [tag://message] or [tag://message|extra]
4 replace or remove

Tag name:
This allows a single tag added to change many tags and supports more complex regex:

        # This is an example of bold and italic in the same add_tag()
        # Tags: [b]message[/b] or [i]message[/i]
        # Output: <b>message</b> or <i>message</i>
        $aubbc->add_tag(
          'tag' => 'b|i', # b or i
          'type' => '2',
          'function' => '',
          'message' => 'any',
          'extra' => '',
          'markup' => '<%{tag}>%{message}</%{tag}>',
        );

Function:
The name gets check to make sure its a defined subroutine then gets passed these variables of the tag.

 sub new_function {
        # $tag, $message, $attrs are the captured group of its place
         my ($type, $tag, $message, $markup, $extra, $attrs) = @_;
         
         # expand functions....
         
         # A) if there is a $message and blank $markup the $message wi
+ll replace the tag.
         # B) if there is both $message and $markup, then $message can
+ be inserted
         # into $markup if $markup has %{message} or any "Markup Templ
+ate Tags",
         # then markup will replace the tag.
         # C) if both are blank the tag doesnt change.
         
         return ($message, $markup);
         # May have to return more so we have better/more controle
        }

Message:
Allows regex or fast regex for 'any', 'href', 'src'
href-> protocal://location/web/path/or/file
src-> protocal://location/web/path/or/file
or /local/web/path/or/file

Extra: supports -> any href src
Allows regex after tag= and message| or if negative pipe is in front will switch to the attribute syntax for attribute range matching.

Attributes syntax and rules:
-Rules
-1) -| must be at the beginning of 'extra'
-2) All attributes listed in 'extra' must be used atleast one time for the tag to convert.
-3) The tag will not convert if an attribute is out of range
-4) Do not use extra delimiters like / and , in 'extra', use as needed.

Attribute syntax:

-|attribute_name/switch{range},attribute_name2/switch{range}

Switches:
n{0-0000} = Number range n{1-10} means any number from 1 to 10
w{0000} = Word range character pre-set limit is '\w,.!?- ' w{5} means text 5 in length or less
w{xx|xx} = Word match w{This|That} will match 'This' or 'That' and supports regex in w{regex}
l{x-y} = Letter range with no length check l{a-c} means any letters from a to c
l{0000} = Length check l{5} means text 5 in length or less

note: usage of X{attribute_name} in the markup will be replaced with the value if everything is correct.
        # tag: [dd=Stuff 7 attr=33]stuff[/dd]
        # output: <dd attr="33" alt="Stuff 7">stuff</dd>
        $aubbc->add_tag(
          'tag' => 'dd',
          'type' => '2',
          'function' => '',
          'message' => 'any',
          'extra' => '-|attr/n{20-100},dd/w{7}',
          'markup' => '<%{tag} attr="X{attr}" alt="X{dd}">%{message}</
+%{tag}>',
        );

        # tag: [video height=90 width=115]http://www.video.com/video.m
+p4[/video]
        # output: <video width="115" height="90" controls="controls">
        #<source src="http://www.video.com/video.mp4" type="video/mp4"
+ />
        #Your browser does not support the video tag.
        #</video>
        $aubbc->add_tag(
          'tag' => 'video',
          'type' => '2',
          'function' => '',
          'message' => 'src',
          'extra' => '-|width/n{90-120},height/n{60-90}',
          'markup' => '<video width="X{width}" height="X{height}" cont
+rols="controls">
        <source src="%{message}" type="video/mp4" />
        Your browser does not support the video tag.
        </video>',
        );
