doctools::idx(n) 2 tcllib "Documentation tools"

Package commands

::doctools::idx objectName

This command creates a new container object with an associated Tcl command whose name is objectName. This object command is explained in full detail in the sections Object command and Object methods. The object command will be created under the current namespace if the objectName is not fully qualified, and in the specified namespace otherwise.

Object command

All objects created by the ::doctools::idx command have the following general form:

objectName method ?arg arg ...?

The method method and its arg'uments determine the exact behavior of the command. See section Object methods for the detailed specifications.

Object methods

objectName destroy

This method destroys the object it is invoked for.

objectName key add name

This method adds the keyword name to the index. If the keyword is already known nothing is done. The result of the method is the empty string.

objectName key remove name

This method removes the keyword name from the index. If the keyword is already gone nothing is done. Any references for whom this keyword was the last association are removed as well. The result of the method is the empty string.

objectName key references name

This method returns a list containing the names of all references associated with the keyword name. An error is thrown in the keyword is not known to the index. The order of the references in the list is undefined.

objectName keys

This method returns a list containing the names of all keywords known to the index. The order of the keywords in the list is undefined.

objectName reference add type key name label

This method adds the reference name to the index and associates it with the keyword key. The other two arguments hold the type and label of the reference, respectively. The type has to match the stored information, should the reference exist already, i.e. this information is immutable after the reference is known. The only way to change it is delete and recreate the reference. The label on the other hand is automatically updated to the value of the argument, overwriting any previously stored information. Should the reference exists already it is simply associated with the key. If that is true already as well nothing is done, but the label updated to the new value. The result of the method is the empty string.

The type argument has be to one of manpage or url.

objectName reference remove name

The reference name is removed from the index. All associations with keywords are released and the relevant reference labels removed. The result of the method is the empty string.

objectName reference label name

This method returns the label associated with the reference name. An error is thrown if the reference is not known.

objectName reference keys name

This method returns a list containing the names of all keywords associated with the reference name. An error is thrown in the reference is not known to the index. The order of the keywords in the list is undefined.

objectName reference type name

This method returns the type of the reference name. An error is thrown in the reference is not known to the index.

objectName references

This method returns a list containing the names of all references known to the index. The order of the references in the list is undefined.

objectName title

Returns the currently defined title of the keyword index.

objectName title text

Sets the title of the keyword index to text, and returns it as the result of the command.

objectName label

Returns the currently defined label of the keyword index.

objectName label text

Sets the label of the keyword index to text, and returns it as the result of the command.

objectName importer

Returns the import manager object currently attached to the container, if any.

objectName importer object

Attaches the object as import manager to the container, and returns it as the result of the command. Note that the object is not put into ownership of the container. I.e., destruction of the container will not destroy the object.

It is expected that object provides a method named import text which takes a text and a format name, and returns the canonical serialization of the keyword index contained in the text, assuming the given format.

objectName exporter

Returns the export manager object currently attached to the container, if any.

objectName exporter object

Attaches the object as export manager to the container, and returns it as the result of the command. Note that the object is not put into ownership of the container. I.e., destruction of the container will not destroy the object.

It is expected that object provides a method named export object which takes the container and a format name, and returns a text encoding keyword index stored in the container, in the given format. It is further expected that the object will use the container's method serialize to obtain the serialization of the keyword index from which to generate the text.

objectName deserialize = data ?format?

This method replaces the contents of the index object with the index contained in the data. If no format was specified it is assumed to be the regular serialization of a keyword index.

Otherwise the object will use the attached import manager to convert the data from the specified format to a serialization it can handle. In that case an error will be thrown if the container has no import manager attached to it.

The result of the method is the empty string.

objectName deserialize += data ?format?

This method behaves like deserialize = in its essentials, except that it merges the keyword index in the data to its contents instead of replacing it. The method will throw an error if merging is not possible, i.e. would produce an invalid index. The existing content is left unchanged in that case.

The result of the method is the empty string.

objectName serialize ?format?

This method returns the keyword index contained in the object. If no format is not specified the returned result is the canonical serialization of its contents.

Otherwise the object will use the attached export manager to convert the data to the specified format. In that case an error will be thrown if the container has no export manager attached to it.
