NAME
amigaguide.datatype -- data type for AmigaGuide databases.
FUNCTION
The amigaguide.datatype is the DataTypes class for AmigaGuide
databases.
METHODS
OM_NEW -- Create a new AmigaGuide object.
OM_GET -- Obtain the value of an attribute.
OM_SET -- Set the values of multiple attributes.
OM_UPDATE -- Update the values of multiple attributes.

TAGS
DTA_TriggerMethods -- List of the trigger methods supported.
Applicability is (G).
DTA_Methods -- List of the methods supported.
Applicability is (G).
DTA_TextAttr (struct TextAttr *) -- Text attribute to use for
the AmigaGuide database.
Applicability is (ISG).
DTA_Name (STRPTR) -- Name of the AmigaGuide database.
Applicability is (I).
DTA_Handle (BPTR) -- File handle for the AmigaGuide database.
Applicability is (I).
DTA_NodeName (STRPTR) -- Document to display.
Applicability is (I).
TDTA_WordDelim (STRPTR) -- Characters used to deliminate words.
Applicability is (IS). Defaults to "t *-,<>()[];"".
AGA_HelpGroup (ULONG) -- Help group that the AmigaGuide object
belongs in.
Applicability is (I).
AGA_Secure (BOOL) -- This tag allows you control whether
AmigaGuide will execute the commands "ONOPEN", "ONCLOSE",
"LINK RX", "LINK RXS" and "LINK SYSTEM". These commands
present a potential security hole if, for example,
AmigaGuide documents are displayed in an e-mail reader
program. To disabled them, set the AGA_Secure tag to
TRUE; in this case AmigaGuide will still recognize the
commands but will not execute them.
Applicability is (ISG). Defaults to FALSE. (V41)
COMMANDS
Commands must start in the very first column of a line, and
can be the only thing on the line. If a line begins with an
@ sign, then it is interpreted as a command.
The following commands can be used in the global section
of a database.
@$VER: <AmigaDOS version string>
Specify the version of the database. This command
must always be in upper-case.
@(C) <copyright>
Specify the copyright notice for the database.
@AUTHOR <name>
Specify the author of the database.
@DATABASE <name>
Must be the very first line of an AmigaGuide document.
@DNODE <name>
Indicates the start of a dynamic node. The AmigaGuide system
uses the callback hooks to obtain the document from a document
provider. This is obsolete, do not use.
@FONT <name> <size>
Specify the font to use for the database.
@HEIGHT <chars>
How high, in characters, the largest document is.
@HELP <name/node>
Specify the name of the help node, which will be accessed
by the Help button. Can be a node in an external database.
@INDEX <name/node>
Specify the name of the index node, which will be accessed
by the Index button. Can be a node in an external database.
@MACRO <name> <commands>
This is used to construct a macro. A macro can be used the
same way as an attribute command, and can only consist of
other attribute commands or macros. The macro list is
searched before the attribute command list is searched. This
is new for V40.
@macro icom "@{i}$1 @{ui}"
...
This is an @{icom "example"} of macro.
@MASTER <path>
Complete path of the source document used to define this
AmigaGuide database.
@NODE <name> <title>
Indicate the start of a node (page/article/section). The first
node, or main node, must be named MAIN. MAIN must be the master
table of contents for the database.
@ONCLOSE <rxcommand>
This is used to specify an ARexx macro file to execute when
the database is closed. The return value of the script has no
effect on the database. New for V40.
@ONOPEN <rxcommand>
This is used to specify an ARexx macro file to execute when
the database is opened. If the script returns an error, then
the database will not be opened. New for V40.
@REM <remark>
@REMARK <remark>
This is used to place remarks in the database. These remarks
are not displayed to the user.
@SMARTWRAP
This is used to indicate that the text of the database is to
wordwrapped using a more intelligent algorithm than @WORDWRAP.
A paragraph doesn't need to be restricted to one physical
line, but paragraphs must be separated by two line feeds.
New for V40.
@TAB <num>
Number of spaces in a tab. Defaults to 8. New for V40.
@WIDTH <chars>
How wide, in characters, the largest document is.
@WORDWRAP
Turn on wordwrapping for the whole database. A paragraph must
be restrained to one physical line.
The following commands can be used within nodes of a database.
\
A backslash is the escape character. A backslash in front of
the @ sign is used to escape it. The backslash has no effect
as an escape character inside commands such as @ONOPEN or
@{".." LINK ..}; in cases like these it is treated as a
regular character.
Please note that AmigaGuide V35 does not treat the backslash
character as an escape character.
@ENDNODE <name>
Indicate the end of a node. Must start at the beginning of a
line.
@FONT <name> <size>
Specify the font to use for the node.
@HELP <name/node>
Specify the name of the help node, which will be accessed
by the Help button. Can be a node in an external database.
@INDEX <name/node>
Specify the name of the index node, which will be accessed
by the Index button. Can be a node in an external database.
@KEYWORDS <keywords>
Keywords of the node. Someday when searching is
reimplemented, there will be a keyword search.
@NEXT <node name>
Node to display when the user selects "Browse >"
@ONCLOSE <rxcommand>
This is used to specify an ARexx macro file to execute when
the node is closed. The return value of the script has no
effect on the node. New for V40.
@ONOPEN <rxcommand>
This is used to specify an ARexx macro file to execute when
the node is opened. If the script returns an error, then
the node will not be opened. New for V40.
@PREV <node name>
Node to display when the user selects "< Browse"
@SMARTWRAP
This is used to indicate that the text of the node is to
wordwrapped using a more intelligent algorithm than @WORDWRAP.
A paragraph doesn't need to be restricted to one physical
line, but paragraphs must be separated by two line feeds.
New for V40.
@TAB <num>
Number of spaces in a tab. Defaults to 8. New for V40.
@TITLE <title>
Title to display in the title bar of the window during the
display of this node. Must start at the beginning of a line.
@TOC <node name>
Name of the node that contains the table of contents for this
node. Defaults to MAIN. This is the node that is displayed
when the user presses the "Contents" button.
@WORDWRAP
Turn on wordwrapping for the node. A paragraph must
be restrained to one physical line.
