\section{Built-in module \sectcode{macfs}}
|
|
\bimodindex{macfs}
|
|
|
|
This module provides access to macintosh FSSpec handling, the Alias
|
|
Manager, finder aliases and the Standard File package.
|
|
|
|
Whenever a function or method expects a \var{file} argument, this
|
|
argument can be one of three things: (1) a full or partial macintosh
|
|
pathname, (2) an FSSpec object or (3) a 3-tuple \code{(wdRefNum,
|
|
parID, name)} as described in Inside Mac VI. 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.
