Convert the specified comcode (text format) into a tempcode tree. You shouldn't output the tempcode tree to the browser, as it looks really horrible. If you are in a rare case where you need to output directly (not through templates), you should call the evaluate method on the tempcode object, to convert it into a string.

• return: The tempcode generated

• LONG_TEXT $comcode: The comcode to convert
• MEMBER $source_member: The member the evaluation is running as. This is a security issue, and you should only run as an administrator if you have considered where the comcode came from carefully
• boolean $as_admin: Whether to explicitly execute this with admin rights. There are a few rare situations where this should be done, for data you know didn't come from a member, but is being evaluated by one.
• ?integer $wrap_pos: The position to conduct wordwrapping at (NULL: do not conduct word-wrapping)
• ?string $pass_id: A special identifier that can identify this resource in a sea of our resources of this class; usually this can be ignored, but may be used to provide a binding between Javascript in evaluated comcode, and the surrounding environment (NULL: no explicit binding)
• object The $connection: database connection to use
• boolean $semiparse_mode: Whether to parse so as to create something that would fit inside a semihtml tag. It means we generate HTML, with Comcode written into it where the tag could never be reverse-converted (e.g. a block).
• boolean $preparse_mode: Whether this is being pre-parsed, to pick up errors before row insertion.
• boolean $is_all_semihtml: Whether to treat this whole thing as being wrapped in semihtml, but apply normal security otherwise.
• boolean $structure_sweep: Whether we are only doing this parse to find the title structure
• boolean $check_only: Whether to only check the Comcode. It's best to use the check_comcode function which will in turn use this parameter.
• ?array $highlight_bits: A list of words to highlight (NULL: none)
• ?MEMBER $on_behalf_of_member: The member we are running on behalf of, with respect to how attachments are handled; we may use this members attachments that are already within this post, and our new attachments will be handed to this member (NULL: member evaluating)

Filter HTML for safety.

• boolean $as_admin: Whether to explicitly execute this with admin rights. There are a few rare situations where this should be done, for data you know didn't come from a member, but is being evaluated by one.
• MEMBER $source_member: The member the evaluation is running as. This is a security issue, and you should only run as an administrator if you have considered where the comcode came from carefully
• integer $pos: The offset of the tag in the Comcode
• integer &$len: The length of the Comcode
• LONG_TEXT &$comcode: The Comcode being parsed
• boolean $in_html: Whether the parser is/was in an HTML region
• boolean $in_semihtml: Whether the parser is/was in a Semi-HTML region

Find if any of some tags are in the stack.

• return: Whether one is present

• array $tag_stack: The tag stack
• array $tags: The tags

Helper function for setting up and juggling variables after reaching a new Comcode tag.

• return: A tuple of new parser settings.

• boolean $as_admin: Whether to explicitly execute this with admin rights. There are a few rare situations where this should be done, for data you know didn't come from a member, but is being evaluated by one.
• MEMBER $source_member: The member the evaluation is running as. This is a security issue, and you should only run as an administrator if you have considered where the comcode came from carefully
• array $attribute_map: The attribute map of the tag
• string $current_tag: The identifier for the tag
• integer $pos: The offset of the tag in the Comcode
• boolean $in_separate_parse_section: Whether the parser is/was in a separate parse section (e.g. a 'code' tag)
• boolean $in_html: Whether the parser is/was in an HTML region
• boolean $in_semihtml: Whether the parser is/was in a Semi-HTML region
• boolean $close: Whether the tag is a closing tag
• integer &$len: The length of the Comcode
• LONG_TEXT &$comcode: The Comcode being parsed
