Standard File Package

It’s been quite a while since last update, which is due to combination of us being busy real-life jobs, and focusing work on this project on a monolithic feature, which in this case is nothing less than getting the Standard File Package to work!

  • MS-BASIC “Save” dialog
  • THINK Pascal “Add Files” dialog
  • TeachText “Open” dialog

Features

This is list of the features which the M.A.C.E. Standard File Package emulation is currently capable of:

  • All 8 selectors for Pack3 (SFPutFile, SFGetFile, SFPPutFile, SFPGetFile, StandardPutFile, StandardGetFile, CustomPutFile, & CustomGetFile). The ones tested are highlighted, but others should work too.
  • Support for custom file dialogs (with assorted hacks to convert MFS-style dialogs, such as the “Save” dialog in MS-BASIC 2.00, to the new HFS-style format)
  • Supports both SFReply and StandardFileReply outputs
  • File listing using List Manager, which displays currently System 6-style SICNs, but with System 7.1+ style spacing (later expandable to use the real icons, when we get Desktop Manager interface)
  • Path popup menu, visually and functionally like on real System 7.x
  • Desktop folder support
  • Focus on selected items (including file list with highlight frame), alterable by mouse or tab key
  • Most of common SF key shortcuts: Clipboard shortcuts, Cmd+S (Save), Cmd+O (Open), Cmd+N (New folder), Cmd+D (Go to desktop), Cmd+Up (Go to parent), Cmd+Shift+Up (Go to root/desktop), Cmd+Down (Open folder), (Cmd+Left/Right to browse volumes not yet implemented)
  • Filename field input filtering (prevents “:” from being used in filenames, which is path separator). Also, copy-pasted filenames will be filtered with proper alert messages.
  • Most of SF items/hooks implemented:
    • Items: sfItemOpenButton, sfItemCancelButton, sfItemVolumeUser, sfItemEjectButton, sfItemDesktopButton, sfItemFileListUser, sfItemPopUpMenuUser, sfItemDividerLinePict, sfItemFileNameTextEdit, sfItemPromptStaticText, sfItemNewFolderUser,
    • Hooks: sfHookFirstCall, sfHookCharOffset, sfHookNullEvent, sfHookRebuildList, sfHookFolderPopUp, sfHookOpenFolder, sfHookLastCall, sfHookGoToDesktop
    • Not yet implemented: sfHookOpenAlias, sfHookGoToAliasTarget, sfHookGoToNextDrive, sfHookGoToPrevDrive, sfHookChangeSelection, sfHookSetActiveOffset
  • File type filtering supported, both by typeList and FileFilterProc

Known issues

Although most of the Standard File Package is functional, and usable, there are still some issues left:

  • Because DirCreate is not yet implemented in NativeFS layer, FindFolder cannot create the Desktop Folder/Trash folders to the file system, thus at least Desktop Folder needs to exist to allow access to “Desktop” level in the SF dialogs. This also prevents “New folder” from actually creating the folders.
  • Eject button does not yet do anything, as the NativeFS volumes are non-ejectable
  • There are minor differences to real System 7.x style SF dialogs, for example with certain elements being a few pixels off their intended locations, and popup menu’s width not always expanding
  • Some custom dialogs don’t yet work exactly as they should, for example THINK Pascal 4.0 “Add files” dialog erases left edge of the applications own custom list located below the SF file list, and for some reason it allows attempts to add folders as source files…
  • Location of the SF dialog is sometimes not correct (for example, Railroad Tycoon’s “Save game” dialog is partially under the menu bar)
  • We cannot yet create app bundles for the currently working freeware/shareware applications that use StandardFile, because when sandboxed the bundle file system is read-only, and thus attempting to save anything to it would straight out fail. To work around this, we need to implement certain changes to the way file system in bundled applications is handled, but we are already working on that for the next release

Other improvements made for Standard File

There were a couple features that were implemented as part of Standard File Package implementation, some of which were necessary to make it work

NativeFS AVL tree balancing and iteration support

One important feature was the need for catalog iteration, which is used by Standard File dialogs to enumerate the files in current folder to be displayed in the file list. This allows for example GetCatInfo to use ioFDirIndex in the parameter block to index specific files inside given directory.

Also, this gave a good excuse to finally implement the actual AVL balancing algorithm in the NativeFS file system, which until now had behaved mostly as a dummy binary tree. Below is a screenshot of how the file system structure was changed by the balancing algorithm:

“Before” and “After” debug visualizations of the NativeFS binary tree data structure (click for larger view)

On the right-hand side, is the unbalanced “dummy” binary tree, and on left-hand side is the same file system, when using AVL balancing algorithm to do the insertions. The deepest nodes were reduced from, in this case, from way over 100+ key comparisons into a rough maximum of 10+.

Popup Menu Control

One important feature of the HFS-style Standard File dialogs is the navigation aid provided by the path popup menu. For this, the Popup Menu Control CDEF 63 was implemented. On real Macs, this was originally part of Communications Toolbox, before it was merged to the System 7.x at some point. The Standard File dialogs use only a subset of its features, but foundation for most use cases was built at the same time, so taking it into more common use should be quite easy. As it uses the Menu Manager’s PopUpMenuSelect trap call, the actual menu selection was already there.

One fun and tricky part though was the need to add MDEF “wrapper” for SF popup path menu, to ensure that the opened popup menu would never be narrower than width of the popup control. To do this, the control imitates how the real Macs did this by adding temporarily a MDEF “wrapper”, which injects modified menuWidth value to the menu after it receives a mSizeMsg message from the Menu Manager, thus modifying the resulting popup menu size.

Picture Button Control

The CDEF 61, picture button, was implemented just to allow adding the “New folder” button to the “put” dialogs. It is quite simple, at least in monochrome version, just drawing a PICT resource as content of a regular push button

Dialog Manager improvements

The StdFilter, which is also used by Standard File dialogs, was improved to add features used by it:

  • Outlining default button with FrameRoundRect
  • Handle “cancel” item’s shortcut key as escape/cmd+dot
  • Track cursor to turn it into i-beam over enabled textedit fields
  • Handle update events for default items

Also, the default shortcut keys (Cmd+X/C/V for Cut/Copy/Paste) were also implemented in DialogSelect trap.

Other news: 68020/68040 support

In other news, Pukka has also been busy adding 68020/68040 support, which includes:

  • Bitfield instructions (bfins, bfset, bftst, bfchg, bfclr, bfextu, bfffo)
  • cas2.b/w/l instruction
  • divs.l/divu.l 32-bit division instructions
  • move16 instruction for 68040
  • Disassembler support for the new and improved instructions
  • Various other improvements
