For +\class{FSSpec}, \class{FSRef} and \class{Alias} handling use the +\module{Carbon.File} or \refmodule{Carbon.Folder} module. For file +dialogs use the \refmodule{EasyDialogs} module. Also, this module is +known to not work correctly with UFS partitions.} + +This module provides access to Macintosh \class{FSSpec} handling, the +Alias Manager, \program{finder} aliases and the Standard File package. +\index{Macintosh Alias Manager} +\index{Alias Manager, Macintosh} +\index{Standard File} + +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 \class{FSSpec} object or (3) a 3-tuple +\code{(\var{wdRefNum}, \var{parID}, \var{name})} as described in +\citetitle{Inside Macintosh:\ Files}. An \class{FSSpec} can point to +a non-existing file, as long as the folder containing the file exists. +Under MacPython the same is true for a pathname, but not under \UNIX-Python +because of the way pathnames and FSRefs works. See Apple's documentation +for details. + +A description of aliases and the +Standard File package can also be found there. + +\begin{funcdesc}{FSSpec}{file} +Create an \class{FSSpec} object for the specified file. +\end{funcdesc} + +\begin{funcdesc}{RawFSSpec}{data} +Create an \class{FSSpec} object given the raw data for the \C{} +structure for the \class{FSSpec} as a string. This is mainly useful +if you have obtained an \class{FSSpec} structure over a network. +\end{funcdesc} + +\begin{funcdesc}{RawAlias}{data} +Create an \class{Alias} object given the raw data for the \C{} +structure for the alias as a string. This is mainly useful if you +have obtained an \class{FSSpec} structure over a network. +\end{funcdesc} + +\begin{funcdesc}{FInfo}{} +Create a zero-filled \class{FInfo} object. +\end{funcdesc} + +\begin{funcdesc}{ResolveAliasFile}{file} +Resolve an alias file. Returns a 3-tuple \code{(\var{fsspec}, +\var{isfolder}, \var{aliased})} where \var{fsspec} is the resulting +\class{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 \class{FSSpec} object for the file itself +is returned). +\end{funcdesc} + +\begin{funcdesc}{StandardGetFile}{\optional{type, \moreargs}} +Present the user with a standard ``open input file'' +dialog. Optionally, you can pass up to four 4-character file types to limit +the files the user can choose from. The function returns an \class{FSSpec} +object and a flag indicating that the user completed the dialog +without cancelling. +\end{funcdesc} + +\begin{funcdesc}{PromptGetFile}{prompt\optional{, type, \moreargs}} +Similar to \function{StandardGetFile()} but allows you to specify a +prompt which will be displayed at the top of the dialog. +\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 initializes the output file name. The function +returns an \class{FSSpec} object and a flag indicating that the user +completed the dialog without cancelling. +\end{funcdesc} + +\begin{funcdesc}{GetDirectory}{\optional{prompt}} +Present the user with a non-standard ``select a directory'' dialog. You +have to first open the directory before clicking on the ``select current +directory'' button. \var{prompt} is the prompt string which will be +displayed at the top of the dialog. Return an \class{FSSpec} object and +a success-indicator. +\end{funcdesc} + +\begin{funcdesc}{SetFolder}{\optional{fsspec}} +Set the folder that is initially presented to the user when one of +the file selection dialogs is presented. \var{fsspec} should point to +a file in the folder, not the folder itself (the file need not exist, +though). If no argument is passed the folder will be set to the +current directory, i.e. what \function{os.getcwd()} returns. + +Note that starting with System 7.5 the user can change Standard File +behaviour with the ``general controls'' control panel, thereby making +this call inoperative. +\end{funcdesc} + +\begin{funcdesc}{FindFolder}{where, which, create} +Locates one of the ``special'' folders that Mac OS knows about, such as +the trash or the Preferences folder. \var{where} is the disk to +search, \var{which} is the 4-character string specifying which folder to +locate. Setting \var{create} causes the folder to be created if it +does not exist. Returns a \code{(\var{vrefnum}, \var{dirid})} tuple. + +The constants for \var{where} and \var{which} can be obtained from the +standard module \var{Carbon.Folders}. +\end{funcdesc} + +\begin{funcdesc}{NewAliasMinimalFromFullPath}{pathname} +Return a minimal \class{alias} object that points to the given file, which +must be specified as a full pathname. This is the only way to create an +\class{Alias} pointing to a non-existing file. + +\end{funcdesc} + +\begin{funcdesc}{FindApplication}{creator} +Locate the application with 4-character creator code \var{creator}. The +function returns an \class{FSSpec} object pointing to the application. +\end{funcdesc} + + +\subsection{FSSpec Objects \label{fsspec-objects}} + +\begin{memberdesc}[FSSpec]{data} +The raw data from the FSSpec object, suitable for passing +to other applications, for instance. +\end{memberdesc} + +\begin{methoddesc}[FSSpec]{as_pathname}{} +Return the full pathname of the file described by the \class{FSSpec} +object. +\end{methoddesc} + +\begin{methoddesc}[FSSpec]{as_tuple}{} +Return the \code{(\var{wdRefNum}, \var{parID}, \var{name})} tuple of +the file described by the \class{FSSpec} object. +\end{methoddesc} + +\begin{methoddesc}[FSSpec]{NewAlias}{\optional{file}} +Create an Alias object pointing to the file described by this +FSSpec. If the optional \var{file} parameter is present the alias +will be relative to that file, otherwise it will be absolute. +\end{methoddesc} + +\begin{methoddesc}[FSSpec]{NewAliasMinimal}{} +Create a minimal alias pointing to this file. +\end{methoddesc} + +\begin{methoddesc}[FSSpec]{GetCreatorType}{} +Return the 4-character creator and type of the file. +\end{methoddesc} + +\begin{methoddesc}[FSSpec]{SetCreatorType}{creator, type} +Set the 4-character creator and type of the file. +\end{methoddesc} + +\begin{methoddesc}[FSSpec]{GetFInfo}{} +Return a \class{FInfo} object describing the finder info for the file. +\end{methoddesc} + +\begin{methoddesc}[FSSpec]{SetFInfo}{finfo} +Set the finder info for the file to the values given as \var{finfo} +(an \class{FInfo} object). +\end{methoddesc} + +\begin{methoddesc}[FSSpec]{GetDates}{} +Return a tuple with three floating point values representing the +creation date, modification date and backup date of the file. +\end{methoddesc} + +\begin{methoddesc}[FSSpec]{SetDates}{crdate, moddate, backupdate} +Set the creation, modification and backup date of the file. The values +are in the standard floating point format used for times throughout +Python. +\end{methoddesc} + + +\subsection{Alias Objects \label{alias-objects}} + +\begin{memberdesc}[Alias]{data} +The raw data for the Alias record, suitable for storing in a resource +or transmitting to other programs. +\end{memberdesc} + +\begin{methoddesc}[Alias]{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. Return the FSSpec for +the file pointed to and a flag indicating whether the \class{Alias} object +itself was modified during the search process. If the file does +not exist but the path leading up to it does exist a valid fsspec +is returned. +\end{methoddesc} + +\begin{methoddesc}[Alias]{GetInfo}{num} +An interface to the \C{} routine \cfunction{GetAliasInfo()}. +\end{methoddesc} + +\begin{methoddesc}[Alias]{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{methoddesc} + +Note that it is currently not possible to directly manipulate a +resource as an \class{Alias} object. Hence, after calling +\method{Update()} or after \method{Resolve()} indicates that the alias +has changed the Python program is responsible for getting the +\member{data} value from the \class{Alias} object and modifying the +resource. + + +\subsection{FInfo Objects \label{finfo-objects}} + +See \citetitle{Inside Macintosh: Files} for a complete description of what +the various fields mean. + +\begin{memberdesc}[FInfo]{Creator} +The 4-character creator code of the file. +\end{memberdesc} + +\begin{memberdesc}[FInfo]{Type} +The 4-character type code of the file. +\end{memberdesc} + +\begin{memberdesc}[FInfo]{Flags} +The finder flags for the file as 16-bit integer. The bit values in +\var{Flags} are defined in standard module \module{MACFS}. +\end{memberdesc} + +\begin{memberdesc}[FInfo]{Location} +A Point giving the position of the file's icon in its folder. +\end{memberdesc} + +\begin{memberdesc}[FInfo]{Fldr} +The folder the file is in (as an integer). +\end{memberdesc} |
