A description of aliases +and the standard file package can also be found there. + +\begin{funcdesc}{FSSpec}{file} +Create an FSSpec object for the specified file. +\end{funcdesc} + +\begin{funcdesc}{RawFSSpec}{data} +Create an FSSpec object given the raw data for the C structure for the +FSSpec. +\end{funcdesc} + +\begin{funcdesc}{RawAlias}{data} +Create an Alias object given the raw data for the alias. +\end{funcdesc} + +\begin{funcdesc}{ResolveAliasFile}{file} +Resolve an alias file. Returns a 3-tuple \code{(fsspec, isfolder, +aliased)} where \var{fsspec} is the resulting FSSpec object, +\var{isfolder} is true if \var{fsspec} points to a folder and +\var{aliased} is true if the file was an alias in the first place +(otherwise the FSSpec object for the file itself is returned). +\end{funcdesc} + +\begin{funcdesc}{StandardGetFile}{\optional{type\, ...}} +Present the user with a standard ``open onput file'' +dialog. Optionally, you can pass up to four 4-char file types to limit +the files the user can choose from. The function returns an FSSpec +object and a flag indicating that the user completed the dialog +without cancelling. +\end{funcdesc} + +\begin{funcdesc}{StandardPutFile}{prompt\, \optional{default}} +Present the user with a standard ``open output file'' +dialog. \var{prompt} is the prompt string, and the optional +\var{default} argument initialized the output file name. The function +returns an FSSpec object and a flag indicating that the user completed +the dialog without cancelling. +\end{funcdesc} + +\begin{funcdesc}{GetDirectory}{} +Present the user with a non-standard ``select a directory'' +dialog. Returns an FSSpec object and a success-indicator. +\end{funcdesc} + +\subsection{FSSpec objects} + +\renewcommand{\indexsubitem}{(FSSpec object method)} +\begin{datadesc}{data} +The raw data from the FSSpec object, suitable for passing +to other applications, for instance. +\end{datadesc} + +\begin{funcdesc}{as_pathname}{} +Return the full pathname of the file described by the FSSpec object. +\end{funcdesc} + +\begin{funcdesc}{as_tuple}{} +Return the \code{(wdRefNum, parID, name)} tuple of the file described +by the FSSpec object. +\end{funcdesc} + +\begin{funcdesc}{NewAlias}{\optional{file}} +Create an Alias object pointing to the file described by this +FSSpec. If the optional \code{file} parameter is present the alias +will be relative to that file, otherwise it will be absolute. +\end{funcdesc} + +\begin{funcdesc}{NewAliasMinimal}{} +Create a minimal alias pointing to this file. +\end{funcdesc} + +\begin{funcdesc}{GetCreatorType}{} +Return the 4-char creator and type of the file. +\end{funcdesc} + +\begin{funcdesc}{SetCreatorType}{creator\, type} +Set the 4-char creator and type of the file. +\end{funcdesc} + +\subsection{alias objects} + +\renewcommand{\indexsubitem}{(alias object method)} +\begin{datadesc}{data} +The raw data for the Alias record, suitable for storing in a resource +or transmitting to other programs. +\end{datadesc} + +\begin{funcdesc}{Resolve}{\optional{file}} +Resolve the alias. If the alias was created as a relative alias you +should pass the file relative to which it is. Returns the FSSpec for +the file pointed to and a flag indicating whether the alias object +itself was modified during the search process. +\end{funcdesc} + +\begin{funcdesc}{GetInfo}{num} +An interface to the C routine \code{GetAliasInfo()}. +\end{funcdesc} + +\begin{funcdesc}{Update}{file\, \optional{file2}} +Update the alias to point to the \var{file} given. If \var{file2} is +present a relative alias will be created. +\end{funcdesc} + +Note that is currently not possible to directly manipulate a resource +as an alias object. Hence, after calling \var{Update} or after +\var{Resolve} indicates that the alias has changed the python program +is responsible for getting the \var{data} from the alias object and +modifying the resource. + + |
