# new([DocVersionTag]) : A new ActiveDoc object. You can also

# specify an alternative doc version tag
|
| 14 |

| 16 |
# parse(parselabel) : Parse the document file for the given parse level
|
| 17 |
# addtag(parselabel,tagname,start,obj,[text,obj,end,obj]) :
|
| 18 |
# Add tags to the parse given by label
|
| 19 |
# grouptag(tagname, parselabel) : Allow a tag to switch context
|
| 20 |
# - if not you can never turn a context off!
|
| 21 |
# checktag(tagname, hashref, param) : check for existence of param in
|
| 22 |
# hashref from a tag call
|
| 23 |
# includeparse(local_parsename, objparsename, activedoc) : copy the parse from
|
| 24 |
# one object to another
|
| 25 |
# currentparser() : return the current parser object
|
| 26 |
# currentparsename([name]) : get/set current parse name
|
| 27 |
#
|
| 28 |
# addignoretags(parsename) : add <ignore> </igonore> tags funtionality to the

| 29 |
# specified parse
|
| 30 |
# opengroup(name) : declare a group to be open
|
| 31 |
# closegroup(name) : declare a group to be closed
|
| 32 |
# allowgroup(name,parse) : allow a group so named
|
| 33 |
# disallowgroup(name,parse) : disallow the named group
|
| 34 |
# restoregroup(name,parse) : restore group access setting (that before last change)
|

# doctype() : return the (type,version) of the document
|
| 36 |
# as specified by the DocVersionTag
|
| 37 |
# --------------- Error handling routines ---------------
|
| 38 |
# verbose(string) : Print string in verbosity mode
|
| 39 |
# verbosity(0|1) : verbosity off|on
|
| 40 |
# line() : return the current line number in the current parse
|
| 41 |
# tagstartline() : return the line number where the current tag was
|
| 42 |
# opened
|
| 43 |
