History of Development Changes
------------------------------
Not all the versions whose numbers appear in the list below have been released
publicly
Items are flagged thus:
[PFE32] : item is specific to the Windows/NT version
[PFE16] : item is specific to the Windows 3 version
0.05.006
--------
EditTextInsertASCIICode now correctly inserts Ctrl+I as a single 0x09 character
regardless of whether the window is set for soft tabs
Added functions CaretTopOfWindow (Ctrl+PgUp) and CaretTopOfWindowSelect
(Ctrl+Shift+PgUp), and a corresponding DDE command CaretTopOfWindow, which move
the caret to the top left of the current window
Added functions CaretBottomOfWindow (Ctrl+PgDn) and CaretBottomOfWindowSelect
(Ctrl+Shift+PgDn), and a corresponding DDE command CaretBottomOfWindow, which
move the caret to the bottom left of the current window
Added functions CaretStartOfText (Alt+Home) and CaretStartOfTextSelect
(Alt+Shift+Home), and a corresponding DDE command CaretStartOfText, which move
the caret to the first non-white-space character in the current line
A number of function names and DDE command names have changed to be more
consistent with others:
EditGotoEnd[Select] now CaretEndOfFile[Select]
EditGotoStart[Select] now CaretStartOfFile[Select]
CaretHome[Select] now CaretStartOfLine[Select]
CaretEnd[Select] now CaretEndOfLine[Select]
Fixed a bug that would cause strange behaviour if WindowTileVertical was
used with the current child window maximized
Fixed a bug that would leave the caret and the insertion point at different
places if EditShowCaret was used with the caret in the line immediately above
or below the visible window
Changed the menu accelerator keys for Edit|Copy and Edit|Cut to be compliant
with standard Windows usage
Fixed a bug that would cause PgUp and PgDn to corrupt the undo stack, leading
to subsequent GPFs or data corruption
[PFE16] Fixed a bug whereby pressing and releasing AltGr would stop keypad and
caret movement keys working again in the session
The default backup mode is now to keep the file in the same directory as the
original, with a file type of ".&&&", and the backup-mode numbers in the
[options] section of the ini file have changed to make this '0'
[PFE32] Circumvented a Win32s 1.1 bug that would corrupt the font size set
in the printer and screen font selection dialogs when running the 32-bit version
under Windows 3.1
0.05.005
--------
Fixed a bug whereby an Edit Copy following a sequence of typing or deleting
would corrupt the undo stack and lead to a GPF sometime later
Menu items now show descriptive text in the status bar when they are selected
Status bar updates are now somewhat smoother and less flickery
[PFE32] DOS Command-with-capture menu and toolbar items are now correctly
disabled under Win32s
Backup now has two modes, selectable with the 'backup-mode' key in the
[options] section of the ini file; files can be backed up either to
subdirectories with the same name, or in the same directory as the original
with a file type of ".&&&"
The documented escape character in search strings is now '\' (so that, for
example, a tab is '\t'). The old '^' escape is still supported for the moment,
but needs to be phased out to allow regular expressions to be implemented
Fixed a bug that would prevent network printers identified by UNCname being
correctly remembered as the default printer between sessions, and would prevent
the settings for such printers being remembered
Fixed a bug that would cause a machine using PathWorks to report a network fail
on drive "?" when PFE was started in the root directory of a drive
[PFE32] File names are no longer forced to be lower case in any circumstances,
avoiding problems in case-aware filing systems like NTFS
The Execute DOS Command to Window and Execute Launch Application dialogs now
record the last 8 command lines executed, and the last 8 working directories
visited
Fixed a bug that would add the wrong title to an attachment icon when mailing a
file via a MAPI mailer
Line numbering is no longer confused when printing a file with Form Feed
characters appearing other than at the beginning of lines
Toolbar buttons and menu items are now set up correctly when a file is opened
in read only mode by File View
Added a language type "TeX"; this differs from plain text only in that "-" is
not considered a break point for line wrapping
0.05.004
--------
Fixed several bugs synchronising undo actions across windows showing the same
file
Added a command line option '/v' which will cause all files named on the
command line to be opened in read-only mode
Fixed a bug that caused brace matching to fail in some files with language type
of "(none)"
Added menu items Execute Program Manager and Execute Task Manager and related
commands
Fixed a bug that could cause file corruption or GPFs when undoing a 'delete
back' action
Fixed a bug that would cause a GPF when the Ins key was pressed when no file
was open
Fixed bugs with non-English keyboards that prevented AltGr+number keys from
generating characters like { and }
Fixed bugs that could interfere with use of the numeric keyboard to synthesise
character codes
File save actions now clear the stack of recorded undo actions by default; this
can be changed with the 'save-clears-undo' setting in the [options] section of
the ini file
Fixed a file handle leak that would occur whenever a write to disk operation
failed
By default, any operation that saves a file to disk will now take a backup copy
of any existing file of the same name before starting; this can be controlled
by setting the "Backup" file mode
Fixed bugs in the EditTextWidenBrace command that would fail to locate closing
braces occurring immediately after an existing selection
[PFE32] Fixed a bug that would cause random GPFs and malfunctions in handling
DDE commands
The EditCopy DDE command now works as documented
Added context help search, to provide help on text in edit windows, available
from the Help Context Help command or a double click on the right mouse button
The Window Tile Vertical command now preferentially locates windows showing
command output at the top of the screen
[PFE16] Fixed a bug that could leave work files created to catch command output
undeleted
The horizontal scroll bar algorithms have been changed, and the thumbtack is
now more usable on files of normal line widths
The name of the file in the current window can now automatically be substituted
in command lines executed by the Execute DOS Command To Window, Execute Repeat
DOS Command To Window, and Execute Launch Application commands
0.05.003
--------
The Execute File Manager, Execute Control Panel and Execute Print Manager
menu items and related commands now work correctly after being broken in
0.05.002
When setting a selection as the default find string, the Edit Find and Edit Replace
dialogs now correctly translate characters with codes greater than 127 into "^xnn"
notation
When undo returns a file to an unchanged state, the toolbar Save button and File
Save menu items are now de-activated
Fixed a bug causing Dr Watson to report parameter validation errors in
ModifyMenu on startup or on load of a keymap file
The EditCMatchBrace command has been renamed EditTextMatchBrace and now has a menu
item mapped to Ctrl+B. If the window has a language of "none", brace matching
is done on {}, [], () and <> without regard to any syntactic elements; if the
language is "C", matching is done on {}, [] and () and (some) C syntax is taken
into account
Added command EditTextMatchBraceSelect, mapped to Shift+Ctrl+B, which acts as for
EditTextMatchBrace but also selects the text between and including the braces
Fixed a bug that would cause problems if brace matching was used when any text
was highlighted
Fixed a bug that made the KeyPad5 key unusable
Added a command EditTextWidenBraceSelect, mapped to Shift+Ctrl+W, which selects
successively larger areas of text between braces, using the same brace location
algorithms as EditTextMatchBrace
Fixed a bug introduced in 0.05.002 that caused the Tab key (and the EditInsertTab
command it maps to by default) to insert a hard tab even if soft tabs were
selected for the window
The "Add Ctrl+Z On Save" and "No EOLN after last line" check boxes in the
Options Default File/Window Modes dialog now work correctly
The default key mappings of Shift+Tab to EditInsertSoftTab and Ctrl+Tab to
EditInsertHardTab have been removed, as these conflict with standard MDI usage
The status bar is now a little prettier when showing static text messages
The applications run by the Execute File Manager, Execute Print Manager and
Execute Control Panel menu items can now be customised by means of entries in
the [managers] section of the ini file
0.05.002
--------
Key mapping has been completely redesigned. Very many more key combinations
(including Alt keys) can be mapped; any or all of Ctrl+A..Ctrl+Z and Esc can be
used as prefix keys; and the Key Mapping dialog has been made far easier to
use. Key map files saved with earlier versions of PFE are not compatible with
the new system.
The OptionsPrefixKeys command has been removed; prefix keys can now only be
configured from within the Key Mapping dialog
Added functions EditInsertTab (mapped to Tab), EditInsertHardTab and
EditInsertSoftTab to insert hard/soft tabs, hard tabs always, and soft tabs
always, respectively
Added command SysSetMenuMode, mapped to F10, to highlight the leftmost item on
the main menu, for compatibility with standard practice
The 16-bit and 32-bit ini and default keymap files have been separated. The
Windows 3.1 version continues to use pfe.ini and pfe.key; the Windows/NT
version now uses pfe32.ini and pfe32.key
Fixed a bug whereby a sequence like Find-overtype-find-overtype would corrupt
the Undo stack
Keyboard macro items have been split from the Execute menu and placed in their
own Macro menu
Added a "Print Manager" item to the Execute menu
The WindowCentreCaret command has been renamed EditShowCaret and now appears
on the Edit menu
Message boxes that support F1 help now announce this in the status bar
Added a system menu item "Save Screen" to activate a standard Windows screen
saver program immediately
Arbitrary character codes can now be specified in Find and Replace strings using
the notation "^xnn", where "nn" are 2 hexadecimal digits
The Replace dialog now contains an "Undo Last" button to undo the last replace
operation
0.05.001
--------
[PFE32] The File Mail command now loads the correct MAPI DLL (MAPI32.DLL
instead of MAPI.DLL)
[PFE32] The File Save As dialog now shows a Network button on networked
machines
The Goto Line dialog now correctly accepts an attempt to specify the final
line of a file
Form Feed characters can now be specified in Find and Replace strings using
the notation "^f"
Moved the hot-spot in the toolbar 'hand' cursor to the tip of the index finger,
to make use more intuitive
Fixed a bug that would cause a UAE if Edit Select All or Edit Select Word were
followed by any cursor movement key that also extended the selection
File loading has been made faster; load time is now much closer to proportional
to file size, rather than degrading progressively as lines are loaded
When a file is opened, the loader now displays the first window's worth of text
as soon as it is read from disk, to give better feedback on what is happening
The Edit Find and Edit Replace dialogs now retain the last 8 strings used, and
these can be reselected from drop-down list boxes. Optionally, the strings can
be recorded at the end of a session and reloaded in the next
The Edit Find and Edit Replace dialogs now default the text in their Find What
edit controls to the first 256 characters of any selected text in the current
window. The previously-used search string will always be available as the first
in the drop-down list
Added a command EditTextInsertASCIICode, mapped to Ctrl+Q by default, which
runs a dialog allowing control characters and other non-typable characters to
be inserted
Implemented a multi-level undo facility to reverse edit actions
Added file modes to strip any trailing Ctrl+Z when a file is loaded;
to automatically add a Ctrl+Z to the end when a file is saved; and to suppress
writing an EOLN terminator at the end of the last line when a file is saved
Added a command HelpScreenMenuHelp, mapped to Shift+F1, which enters the
help system at an appropriate point when the mouse is clicked on a menu command
or an area of the tool bar or status bar
0.04.009
--------
[PFE16] PFE now can detect it is running under WOW and tailor things
accordingly
Fixed a bug that limited the maximum value of the 'mru-files-shown' ini file
option to 5 instead of the documented 8; also set the minimum value to 0
rather than 3
Added an ini file option 'sound-beep' to suppress all beeps associated with
message boxes
Ctrl+Backspace can now be mapped correctly
Cleared the confusion in handling mapping of Shift+Backspace; for the moment
this has required that Ctrl+Shift+H is no longer mappable
Fixed a bug that caused a print operation to fail when the last line of the
file was printed on the last line of any page
The Edit Goto Line dialog now has a system menu
The OK button in the Edit Goto Line dialog is now enabled only if a line number
has been typed in the Line To Goto edit control
The Edit Goto Line dialog now accepts line numbers preceded by "+" or "-" as
meaning relative to the current line number
Fixed a bug in the Default File/Window Modes dialog that would cause the tab
size to be set as a negative value if soft tabbing was selected
Edit controls in dialogs that accept numeric input are now insensitive to
leading and trailing white space
The Key Mapping dialog now prompts if there are unsaved changes when the Load
button is clicked, and correctly resets the "unsaved changes" flag
Changes to windows made by allowing keys to auto-repeat, and tracking of mouse
selections, should now appear better on slower machines
The "auto-indent" window mode is now respected by the routines that wrap text
as it is being typed
Fixed some bugs in control block chaining that could cause UAEs when closing
some of a large number of open windows and/or files
Installing a printer of an existing type, but connected to a different port,
while PFE is running no longer confuses the Print Setup dialog over which
printer is the default
Printers connected to files by means of a "pathname=" line in the [Ports]
section of win.ini are now handled correctly, and the filename is not corrupted
When text wrapping is active, typing at the end of a line that already extends
past the wrap column now correctly breaks the line at the break point closest
to, and left of, the wrap column
[PFE32] Circumvented a Windows/NT bug that caused a GP fault when the Apply
button was clicked in the Options Default File/Window Modes dialog and some
other dialogs (October 1992 beta only)
The ini file [options] setting "auto-unix" has been renamed "auto-format"
If PFE is exited with the tool bar floating and also hidden, the tool bar is
now drawn correctly the next time it is made visible
The Edit Cut tool bar button, and the key mapped to EditCut, are now correctly
disabled if the current file is marked read-only
PFE now correctly responds when printers are changed via Control Panel.It
no longer records the driver name in its ini file, so that it will not try to
use an obsolete driver after an upgrade
Fixed a bug that caused a parameter validation error in GetWindowLong if
the left button was double clicked in the menu bar and no file was open
Fixed further bugs that would cause looping replacing strings containing
"^n" characters
Fixed a bug causing a parameter validation error in SetWindowText when the
"Remap Key" button of the Options Key Mapping dialog was pressed
[PFE32] Full template functionality is now available. PFE32 now correctly uses
the same file format as PFE16; template files created under earlier versions of
PFE32 will no longer work
[PFE32] The system shutdown options in the "Exit Windows/NT" dialog now
work correctly
[PFE32] It is now possible to run DOS commands and capture output
Fixed a bug that would cause PFE to hang or misbehave while searching if the
text contained characters > 127
The file position in the status bar is now updated correctly after a succesful
search from the Find or Replace dialog
[PFE32] File Insert no longer fails with a "Cannot get file size" message
Fixed a bug that would cause a UAE when performing a template action after
detaching a template file
The File Save All command now saves all open files, and not only altered ones,
if the ini file option 'allow-save-always' is set
A file's save format now cannot be altered if the file is marked as read only
Changing the format a file is saved in via the modes dialog or with the status
bar now marks the file as changed
Added a DDE command EditGotoLine
Added an ini file option 'auto-file-action' to have PFE either create an empty
edit window or show the File Open dialog automatically if started with no file
names on the command line
Files whose first character is a Form Feed (0x0c) character now print correctly
Fixed numerous bugs affecting synchronisation of changes in duplicated windows
File Close now correctly asks if changes should be saved if the current file
is visible in more than one window
[PFE32] File Close now works correctly always
Fixed a bug that would randomly cause the ini file option 'open-maximized' to
be ignored
Fixed a printing bug that would lose the header line giving the file name when
a top margin was selected
[PFE32] Fixed a bug causing a UAE trying to display an empty line that is
not within a selection
[PFE32] Drag and drop of files from File Manager into the PFE window now
correctly opens them
Fixed a bug that could produce "Bad offset" warnings or misplace the caret
when inserting files larger than 8K whose last lines did not end in CRLF or LF
General release on April 28 1993
0.04.008
--------
[PFE32] Fixed a bug that would cause a UAE on clicking the OK box of any font-
selection dialog
Added a 'toolbar-size' option to the ini file to override the automatic sizing
of the tool bar
Removed the confusing Edit|Undo menu option; it will reappear when Undo is
actually implemented
General release on February 1 1993
0.04.007
--------
Fixed a bug that caused DDE errors to occur on startup if PFE was invoked with
file names on the command line
Added a "/k" command line option to allow a key map file to be specified for
loading at startup in place of pfe.key; this option implies "/m"
Instances started with command line options implying multi-instance mode are no
longer erroneously activated by a succeeding start without options
Instances started with options implying multi-instance mode no longer update
the most-recently-used-file list on termination
Added a "/d" option to force the DDE server to be enabled at start-up even if
options implying multi-instance mode are used
Where multiple printers of the same type are configured on different ports, PFE
now shows them all in the print-related dialogs instead of only the first
[PFE32] F1 now correctly activates context-specific help in dialogs
When a search operation is initiated from a Find or Replace dialog, the window
will be redrawn to show the matching string in the second line from the top, to
try to avoid it being hidden by the dialog box
The function names EditIndent, EditUndent, EditLowercaseSelection,
EditUppercaseSelection and EditTransposeCharacters have been changed to be
EditTextIndent, EditTextUndent and so on; key mappings to the old names will
need to be re-instated
Fixed a bug that could put PFE into a loop when using the Window Next command
with all edit windows iconic
The most-recently-used-file list can now be up to 64 names long; names not
shown on the File menu can be selected from a "More Files" dialog
Added a Window Select command, mapped by default to Ctrl+W, to select from many
open windows; the dialog for this replaces the standard MDI "More Windows" dialog
[PFE32] The DDE service name has been changed to be "PFE32", to separate the
services of the Windows/16 and Windows/NT versions
Remedied the omission of the Ctrl+X Ctrl+S combination from the list of keys
that can be mapped
The DDE command EditInsertString has been renamed EditInsert
Fixed bug that would leave a caret in the middle of the Find or Replace dialog
when a match was found
Mappable functions EditRepeatFind and EditRepeatReplace have been renamed
EditRepeatLastFind and EditRepeatLastReplace
Added an Options|ResetFile/WindowModes command to reset the modes of the
current window and the file it shows to those appropriate to the file type
The Printer Font dialog now correctly returns focus to its parent dialog on
close
Limited release to beta testers 20 January 1993
0.04.006
--------
Dialogs now show help if F1 is pressed, as well as with their Help buttons
Fixed a bug introduced in 0.04.005 that caused Ctrl+End to leave the caret
showing beyond the actual end of file
Fixed a bug introduced in 0.04.005 that caused the File Write dialog to be run
twice
Fixed a bug that would leave bitmaps undeleted on exit if ever child windows
were closed by double-clicking in their system menu boxes
[PFE32] Scroll bar elevators now work
[PFE32] Child windows can now be closed by double-clicking in their system menu
boxes
Automatic horizontal scrolling now endeavours to keep the caret as far right in
a window as possible, which should improve the appearance of searches, word
wraps and the like
A command line option "/m" now allows you to force a new instance of PFE to
start even if another is running
Added a "DDE Server" command on the Options menu and equivalent mappable
functions to allow the DDE server system to be turned on and off at will
Added a DDE data item FileName to return the name of the current file
Added a DDE data item WindowTitle to return the title of the current window
Added a DDE command EditFind to perform string searches
Added DDE Poke items OpenFiles and ViewFiles to allow opening of several files
in a single operation over a DDE link
The mechanism for passing command line filenames to previously-running
instances has been rewritten to run asynchronously from the client and pass all
the filenames in one transaction, rather than in separate commands
The mechanism for pasting data over a DDE Poke link has been rewritten to run
asynchronously from the client
Limited release to beta testers 10 January 1993
0.04.005
--------
The status bar has had its intelligence raised, and responds to double-left-
clicks thus: in the line/column area, it starts an Edit Goto Line dialog; in
the Read-Only area it toggles read-only mode; in the Recorder status area it
toggles the recorder on and off; in the Wrap area it toggles line wrap on and
off; in the insert/overwrite area it toggles between the settings. The only way
to banish the status bar is now from the Options menu.
The format a file will be saved in (DOS/Unix) is now shown in the status bar,
and can be altered by double-clicking
The mouse cursor now changes shape to give cues when over the tool bar, over
the status bar, and over a selection
Fixed a bug introduced in 0.04.004 that caused a UAE loading files in UNIX
format
The mouse cursor is now hidden when the user starts typing
Drag-and-drop operations are now disabled completely in read-only files
Fixed a bug that caused a UAE when a drag-and-drop area extended over more than
one line, and the drop target was in the same line as the end point of the
highlight
Fixed a bug that would cause PFE to loop when replacing all occurrences of end-
of-line (^n) characters
Fixed a bug whereby the default file name was not set up in the File Save As
dialog edit control as it should have been
Tool bar buttons are now set correctly if a file is changed from being read-
only to being writable
If a DOS command with output capture action re-uses an existing output window,
the caret is now shown in the correct position relative to the new contents
The Execute DOS Command to Window dialog now has an option to position the
window at the end of the output rather than at the start; this is now the
default behaviour
On startup PFE now checks whether files in the most-recently-used list of files
that are on local hard disks still exist, and silently removes them if not
When a drag-and-drop operation is aborted by pressing ESC, the caret is
returned to the start of the highlighted area and the window redrawn to show it
Added a File Save All command that will save all altered files, store all
altered templates, and save all altered template files
The "Templates" item on the main menu is now "Template" to match every other
reference to it
The help file has been completely rewritten and may now even be useful;
corresponding changes have been made to the Help menu
Dialogs now have Help buttons to give instructions on their use
Dialogs now all have system menu boxes
The File Save command now detects that a window showing DOS command output
has no associated file name, and turns itself into File Save As
0.04.004
--------
A Replace All operation no longer misses out a match in a selection
produced by a previous Replace or FindNext
If the current window is iconic when a Find or a Replace dialog is started,
the window will be restored before the dialog box is shown
Added an ini file option 'allow-save-always' to allow the File|Save menu
item and the corresponding tool bar button to function even if the current
file has not changed
Fixed a bug that erroneously lit the tool bar cut and copy buttons after a
Find operation with 'select matching text' turned off
Fixed a memory manager bug that could cause data corruption or UAEs in
complex circumstances most often seen in replace operations in large files
Added an ini file option 'minimize-on-empty' that iconizes the main window
when the last child window in use is closed
File names shown as the titles of windows are now abbreviated to exclude as
much as possible of the current directory name
Corrected mis-spelling in status bar help line for the 'Repeat DOS Command'
toolbar button
PFE now records its state in the ini file correctly if Windows is shut down
while it is running
When a file name is changed (by File|SaveAs or File|Name) the file and window
modes now change to match those appropriate to the file type in the new name
The status bar INS/OVR flag is now updated correctly if insert mode is turned
on or off using the 'Set Current Modes' dialog
Edit|Text|Indent and Edit|Text|Undent functions now allow the current line, or
all the lines in a selection, to be indented or undented by one tab stop
The Shift+Backspace key combination is now mappable to functions
Automatic text wrapping of lines as they are typed is now implemented
An 'Exit Windows' item has been added to the system menu, permitting Windows to
be closed down in a variety of exciting ways from within PFE.
When the 'Save Changes' message box is shown on exit from the Key Mapping
dialog, focus is now correctly restored to the current edit window
The status bar now shows feedback on the progress of load and save operations
Fixed a bug that caused a spurious blank line to be created whenever a file
being loaded contained a CR-LF byte pair that straddled a storage block
boundary
Auto-indenting is now carried out if a line is split, or if a newline is
inserted, when the caret is in the middle of a line as well as at the end
PFE now has a marginally better knowledge of C syntax and handles brace lineup,
auto-indent and brace matching in a rather more useful way in C language files
Internal re-organisation needed for porting to Windows/NT
Added a way to circumvent a Windows/NT bug that refuses to show fixed-pitch
fonts in the Choose Font dialogs, affecting both the 16- and 32-bit versions;
putting 'fix-font-bug=1' in the [options] section of the ini file will show all
fonts, but attempts to select variable-pitch ones will be rejected [there is no
plan for PFE to support variable pitch fonts]
The File|Name, File|Write and File|Save dialogs now default the file name to
that of the current file, if it has one
The File|Open, File|Name, File|Write and File|Save dialogs now independently
record the filename filter last used, and take that as the default on the next
invocation
A drag and drop operation can now be aborted by pressing ESCAPE before
releasing the left mouse button
Up to five user-defined items may now be added to the Help menu, each one
invoking a specified Windows help file. The menu item Help|WindowsSDK has been
deleted; you should insert an entry in the [help-files] section of the ini file
to access it.
Limited release to beta testers 21 December 1992
0.04.003
--------
The tool bar buttons are now maintained at approximately the same physical
size on all screen resolutions
Changed the way child windows are opened maximized for a better visual
appearance, avoiding a transient restored state
Files can be mailed using MAPI-compliant mail systems
The way that the termination of DOS commands is detected has been changed,
and no longer calls GetModuleUsage with an invalid module handle
The menu item for "Repeat DOS Command", and the "Run DOS Command" toolbar
button, are now disabled while a DOS command is running
Search and Replace operations now use the common dialogs. To be consistent,
"Search" has been changed to "Find" in menus and command names
The file name is now shown in the print Abort dialog, and a faulty call to
SetDlgItemText with an invalid control handle corrected
Fixed a bug that caused a UAE if a strictly empty file was loaded and
a character was typed (this would happen if PFE was used as the editor for
WinQVT/net's POP mailer)
The cursor now changes to an hourglass when cutting or deleting a selection
The format of the [modes] section of the ini file has changed slightly. Soft
tabs are no longer recorded as a -ve tab size, but as a positive value with
a bit flag in the window modes word. Versions of PFE from here on will accept
the old format on startup, but write the new one
Auto-indenting now inserts the relevant number of spaces instead of a single
tab character if the window is set to use soft tabs
Fixed a bug that caused a non-ANSI screen font selected in one session to
be incorrectly selected on subsequent sessions
0.04.002
--------
The "file changed" marker in the status bar has been changed from "C" to "#"
to avoid confusion with language types
Added a standard key mapping Ctrl+Shift+O to invoke EditSplitLine
Fixed random return value from routine that detected a second PFE instance
Characters with ASCII values > 127 are now printed correctly as ANSI characters
rather than as digraphs
Extending a selection generated by a successful search no longer causes a UAE
It is now possible to set the screen font and printer font to non-ANSI as well
as ANSI fonts
The most-recently-used-file list is no longer erroneously appended to the
system menu instead of the File menu if the MDI child is started maximized
Files specified on the command line with names beginning '\' are now handled
correctly
Search-and-replace no longer disregards the 'read-only' status of a file
The filter for "*.exe" files in the Browse sub-dialog of the "Configure
Windows Tools" dialog now works correctly
Fixed a bug whereby some files would not be saved on exit or from a
File|CloseAll operation if some altered files were untitled
General release as the second beta version on 3 November 1992
0.04.001
--------
Improved scrolling behaviour when dragging a selection with a mouse and
fixed several bugs that caused the selection to freeze
Fixed a bug introduced in 0.03.036 that stopped drag-and-drop copy from
working
Fixed some UAEs when scrolling with PageUp when the caret is in the top line
of the screen, with less than one window's worth of lines above it
Fixed inaccurate scrolling down by pages when less than one window's worth
of lines remained below the window and the bottom line of the window was
not one full row in height
If PFE is terminated when the tool bar is a floating window, it will now
restart with the tool bar as a floating window
Making PFE iconic when the tool bar is floating no longer erroneously changes
it to a bar on the right hand border
The way PFE locates the Windows SDK helpfile for the Help|SDK function has been
made more sensible. If the [options] section of the ini file contains a
'sdk-helpfile' key, the name given is used; if not, PFE looks for first
"win31wh.hlp" and then "sdkwin.hlp" on the PATH and uses the first one found.
Limited release to beta testers for validation as the possible beta 2 version
on 19/10/92
0.03.036
--------
When configuring the first tool in the Configure Windows Tools dialog, the
Add button now correctly becomes active as soon as something is typed in
the Command Line edit control
The default mapping of Ctrl-P to File|Print is now shown on the menu
Fixed a bug whereby, if PFE was maximized, made iconic, and closed from the
icon's system menu, it would restart restored rather than maximized
Added an ini file setting "start-maximized" to the [options] section, which
controls whether PFE starts maximized, overriding the saved state at last
closedown
Shift-PgUp and Shift-PgDn no longer cause UAEs or select the wrong sections of
text
Added an ini file [options] setting "track-vertical-thumbtack" that controls
whether PFE scrolls to follow vertical thumbtack dragging
PFE now leaves selected text highlighted after it is copied to the clipboard.
An ini file [options] setting can specify that highlighting is to be removed
Key names in menus and the Key Mapping dialog now use '+' rather than '-'
to link components, to be CUA compliant
The Settings menu has been renamed Options
Corrected a bug in the command line parser that would cause DDE commands and
ini file lines whose last argument was in quotes to be mis-parsed
Added a most-recently-used files list to the File menus
Added a menu option and tool bar action to repeat the last DOS command run
Corrected PgUp and PgDn and scroll bar page moves when caret is not within the
window
The default setting for the 'auto-unix' key in the [options] section of the
ini file is now 1, so that UNIX files will save in UNIX format by default
The Browse Application dialog started from the Browse button in the Configure
Windows Tools now uses a filter showing only "*.exe" files
0.03.035
--------
Improved icons
Some development code that was accidentally left active and caused a UAE
when Ctrl-Z was pressed for an Undo has been removed; undo actions are not
yet supported
Fixed a bug that prevented disabling only a subset of the possible prefix
keys
Dragging the mouse to extend a selection should no longer leave a caret trail
on slower machines
Windows are now scrolled to track movements of the thumbtack in the vertical
scroll bar
All references to "Development Tools" in menus and functions have changed to
use "Windows Tools", to clarify the intended use of the facilities
Details of the actual command line used and working directory are now stored
for all Windows Tools between sessions, and not solely for the last one
used
Limited release to beta testers 05/10/92
0.03.034
--------
When a window is duplicated, the second copy's scroll bars are now set
correctly
Fixed a bug whereby, if a window lost focus when its caret had been scrolled
out of view, the caret would be wrongly placed when the window regained
focus
The tool bar is now disabled when PFE is waiting for the second key of a
two-character command sequence
If the left button is pressed in the tool bar, and the mouse is moved out of
the tool bar before it is released, focus is now correctly restored to the
current window
If the left button is pressed in a tool bar button and the mouse then moved
off the button, the button will return to its down state should the mouse
move back onto it
When dragging the tool bar from a border, the state will now not change
unless the mouse cursor is outside the tool bar when the left button is
released
A 1-pixel gap between the area showing line numbers and the area showing the
text in a window has been eliminated
Ctrl-K can now be used as a prefix key
The prefix keys ESC, Ctrl-B, Ctrl-F, Ctrl-K and Ctrl-X can individually be
enabled and disabled from a sub-dialog of the key mapping dialog. When
disabled as a prefix key, each of them can be mapped to a function as required.
By default they are all disabled, and the hard-coded key mappings are now fully
CUA-compliant. As a result the format of .key files has changed
Pressing TAB when no file is open no longer causes a UAE
Page Down now does nothing if the final line of the file is visible in the
window
Added a File|Name menu item and equivalent DDE command that allows the file name
associated with a window to be changed without writing any data to a disk
The EditPageUp and EditPageDown functions have been redesigned to maintain the
caret in the same screen row, and to keep a memory of the caret column. This
means that a page down followed by a page up returns to exactly the starting
position
Vertical scrolling using the scroll bar now does not move the caret within the
file, but moves it with the text
Selections are no longer removed when the data is scrolled using the vertical
thumbtack
Functions EditShowNextLine, EditShowPreviousLine, EditShowNextPage and
EditShowPreviousPage have been added to give keyboard equivalents of vertical
scroll bar actions
Menu items File|Open, File|New and File|Print are now bound by default to Ctrl-O,
Ctrl-N and Ctrl-P as recommended in the CUA
Pressing a key that is not mapped no longer causes the window to scroll to
show the caret if this is not initially visible
0.03.033
--------
Fixed a bug whereby directories whose names were a single letter or '.' were
not accepted in the Working Directory controls of the DOS Command and Launch
Tool dialogs
Scroll bars no longer respond to the first mouse click if their window is
inactive; the click simply activates the window without disturbing its state
The caret now follows the mouse cursor in a somewhat more friendly fashion
when dragging with the left mouse button down
The File Print dialog now allows line numbering, line wrapping and page header
options to be specified. The corresponding window mode values are now the
default settings for the dialog rather than the active settings
An initialisation file option now allows new windows to be created always
restored; always maximized; or maximized if and only if an existing window is
also maximized. These options can also be made conditional on the main window
being maximized too.
ESCAPE now closes the About dialog box
The vertical elevator is now correctly positioned after a search or a
Window|CentreCaret operation
The ini file and keymap files are now found correctly if the Windows directory
is in a JOINed or mounted directory that appears as the root directory of a
drive
Printer font selection now uses the Font common dialog
Filenames are now correctly set in the document title used by Print Manager
when a file is printed
Window titles for unnamed files, unnamed templates and command output have been
redesigned; the title for an unnamed template and a command output window now
includes a sequence number
PFE no longer beeps to warn of an impossible scroll request (e.g. scrolling
up a line when already in the top line)
The Template|SaveFile and Template|Store menu items no longer both have 'S'
as their hot key
The Template|SaveFile menu item now has an ellipsis to show a dialog will be
run
The File menu has been re-arranged for better CUA compliance
The top and bottom margin checkboxes are no longer confused in the Print
Setup dialog
0.03.032
--------
Changing file and window modes with the Settings|CurrentSettings dialog no
longer erroneously lights the toolbar Cut button
Files can now be loaded and saved in UNIX format, using LF as a line terminator
Clipboard data in excess of 64K is now handled correctly
The File Open and File View dialogs now allow multiple files to be selected
Wildcarded file names can now be given both on the command line and in the
DDE commands FileOpen and FileView
Fixed a bug in which an invalid window handle was passed to IsIconic on
startup, which was trapped by the debugging kernel
Captured output from DOS commands can now be shown in an existing Command
Output window as an alternative to creating a new window
Windows can now be tiled in a custom vertical pattern that maximizes their
width
A new function FileAbandon and corresponding DDE command allows a changed file
to be closed with the changes discarded
0.03.031
--------
Cursor resource memory is now properly freed after the toolbar has been
dragged with the multi-headed-arrow cursor
Text drag-and-drop is now implemented
When a window is duplicated, the copy now correctly inherits the text colours
and language type of the parent
Fixed a bug whereby a non-stock font would not be deleted on termination
0.03.030
--------
If an invalid line number is entered as the target in the Goto Line dialog,
focus is now set back to the control after the error message is shown
Menu items to select the fixed pitch ANSI, OEM and SYSTEM fonts have been added
The "Free Key" and "Free All Keys" buttons in the Key Mapping dialog have been
renamed to "Unmap Key" and "Unmap All"
Selecting Window|Next when all windows are iconic now restores the current
window rather than entering an infinite loop
The Status Bar now uses the Windows variable-pitch ANSI font
Added an Edit|SelectAll menu item to select an entire file
Maximized MDI child windows can now be closed by double-clicking in the
system menu box
The "goto start of file" and "goto end of file" operations are now by default
invoked by Ctrl-Home and Ctrl-End rather than Ctrl-PgUp and Ctrl-PgDn, to
be in line with standard Windows practice
Selected text is now displayed in the correct text and background colours as
set up from the Control Panel
If the current window is set to have a language type of "C", Edit|SelectWord
treats an underscore character as alphanumeric, so that identifiers such as
WM_CREATE can be selected as a single entity
Fixed a nasty memory manager bug that could cause a UAE inserting a newline
after a line deletion in very complicated circumstances to do with the fact
that line control blocks are held in groups of 1024
The vertical thumbtack is now set more sensibly, reflecting the line number
of the line at the top of the window
Positioning within a file containing more than 65535 lines by moving the
vertical thumbtack now works correctly
Tabstop ordering in the Print Setup dialog has been made sensible
Limited release to beta testers 19/08/92
0.03.029
--------
Selecting text with a mouse has been enhanced. Holding SHIFT down while clicking
the left button will select between the caret and the mouse cursor, or will
extend an existing selection
The Window|Widen menu option will now restore iconic or maximized windows before
resizing them
Shift+click on the "Toggle Keyboard Recorder" toolbar button now replays the
keyboard recording
The 'Save File' toolbar button now invokes the TemplateStore function if the
current window contains a template. The button state now correctly reflects the
change state of template windows
The caret now changes size to indicate whether a window is in insert or overwrite
mode
Selecting a word by double-clicking the mouse or using Edit|SelectWord no
longer selects white space to the right of the word
Fixed a bug whereby, after doing a Window|Tile, the wrong window would respond
to keyboard input and scroll bar actions
Fixed a bug which would sometimes cause File|Insert not to close the file that
was inserted
0.03.028
--------
The font used in edit windows may now be selected from all the available
fixed pitch ANSI screen fonts
The 'search' dialog now permits you to specify whether the matching string
is to be selected or not (the default is settable in the ini file). The
dialog also allows you to choose to extend the selection from the initial
caret position to the matching string
All dialogs have been redesigned to use 8pt MS Sans Serif text instead of
10pt System
The algorithm for positioning the caret in the text when the left mouse
button is clicked has been improved: clicking in the left half of a
character cell places the caret to the left of that character, and clicking
in the right half places it to the right
The "Key Mapping" dialog now permits a key to be remapped from one function to
another with a single button click, instead of needing first to free it and
then map it to the target function
The "Free All Keys" button in the "Key Mapping" dialog now requests
confirmation before proceeding
0.03.027
--------
Minor internal changes to make the source compatible with MSC 7.0
The Edit|Text|Uppercase and Edit|Text|Lowercase functions now correctly
mark the file as being changed. They also produce an error if used
on a read-only file. Both now handle characters with ASCII codes > 127
properly; note, though, that neither these, nor anything else in PFE,
will work with Kanji or other languages using 2-byte codes
0.03.026
--------
Altered files can now be saved to disk automatically before running a
DOS command or launching an application or a development tool
The details of the last-used DOS command, application or development tool
are now remembered between PFE sessions. The details of the last used
development tool are also shown as the default each time the dialog is
started
The Run DOS Command dialog box now has a Browse button
0.03.025
--------
Extra functions are now available from the toolbar by using the SHIFT and
CONTROL keys in combination with the left mouse button. See the help file
for details.
The "Window" menu item on the menu bar has been moved to be the last apart
from "Help", to match the standard menu layout for MDI applications
Windows may now be set to use "soft tabs": tabs will be inserted
as an appropriate number of spaces rather than as single 0x09 characters
The "Insert Template" toolbar button is now correctly set as template files
are attached and detached
The TemplateInsert, TemplateEdit, TemplateStore and TemplateStoreAs functions
no longer cause UAEs if no template file is attached
Files that have the "read only" attribute set are opened in read-only mode,
regardless of the "read only" button state in the File Open dialog
Characters with ASCII codes from 128-255 can now be inserted from the
keyboard
0.03.024
--------
Many of the functions shown in the Key Mapping dialog, and the
equivalent DDE commands, have been renamed. They now correspond better
to the menus where they are held (or would be held)
A bug whereby a DDE Poke operation received DDE_FACK on a fail and
DDE_FNOTPROCESSED on successful termination has been cleared
A successful search now sets the toolbar cut and paste buttons correctly
Several new DDE commands and enquiries added
The syntax of the DDE commands CaretLeft(), CaretLeftWord(), CaretRight()
and CaretRightWord() is now changed so that each takes two mandatory
arguments. The first is the count of the number of characters or words
to move, and the second is 1 to extend a selection and 0 not to do so
To avoid confusion over what it is, the support module PFEDOS.EXE, which
is used by PFE to handle output redirection in DOS commands, has been renamed
$PFEDOS.EXE, which hopefully looks less like a DOS version of PFE. The
associated PIF file is now called $PFEDOS.PIF to match
Using selection-extend keys like Shift-Left after marking a selection with
the mouse now has the desired effect. Other minor bugs when moving the
caret with Shift down to extend selection have been cleared
Caret movement keys can now be remapped. This has required an incompatible
change in the format of key mapping files, so that files saved with
earlier releases of PFE cannot be used
The semantics of the default PgUp and PgDn mapping is slightly altered; if
line 1 is at the top of the window, PgUp moves to the start of the file, and
if the last line is at the top of the window, PdDn moves to the end of file.
Shift-PgUp and Shift-PgDn are now mapped to page up/down moves that extend
the selection
To be compatible with standard MDI practice, Shift-F4 now maps to
WindowTile by default, and Shift-F5 to WindowCascade. TemplateInsertMarker
has moved to F6, and CaretCentre to Ctrl-F5
The Goto Line dialog has been enhanced to allow optional extending of
a selection
^T is now accepted as meaning TAB in a search or replace string, as well
as ^t
0.03.020
--------
Released as the Beta 1 version of PFE 28/07/92
------------------------------------------------------------------------------
Reported bugs that have not yet been cleared
--------------------------------------------
The toolbar paste button is not updated correctly if another application is
activated and changes the clipboard contents
If the user tries to save an un-named template, calling it by the same name as
an existing one, and presses CANCEL in response to the confirmation prompt,
the template window is nevertheless given that name
When a selection ends with the cursor at the left of an empty line, the
display code draws a half-cell highlight on that line erroneously
Duplicate windows should have ":sequencenumber" appended to their titles
Double-click to the right of a line, or in the right-hand half of the last
character in a line, should select the word to the left of the mouse cursor
With text like "point.x = something", double clicking on the right hand side of
the 'x' or left side of the following space uses '.' as a word delimiter when
extending the selection left. This is inconsistent with how extensions right
work, or when the '.' is followed by more than one character
The various "modes" dialogs show error messages when invalid file types are
given, but add them to the list anyway
When the last screen of a file is visible, a PageDown action should take the
caret to the end of the file; similarly for PageUp in the first screen of the
file
A DOS-command-with-capture operation sometimes seems to ignore the specified
working directory and runs the command in the Windows directory
The File Open dialogs should show deeper filter lists; the Microsoft default
depth of 3 lines is pathetic
When a child window exists and is maximised, pressing the first character of a
two-character command sequence grays all the menu bar items, instead of leaving
just the Help menu active
The File Write dialog does not allow Unix format to be specified
Vertical scroll bar handling when the end of a file is visible needs to be
improved
Automatic horizontal scrolling can still sometimes fail to position the caret
optimally as far right as possible in a window
Any line where the number of characters times the width of a character in
pixels exceeds 32K will not get drawn correctly in many cases
Some parts of PFE still impose a limit of 1024 characters in a line; for
safety, do not operate with lines longer than this
Text wrap does not occur unless typing at the end of a line
Font characters that occupy the full width of a cell (e.g. "V" in 8pt Courier
New) may leave a single dot behind when moved by an insert to their left
It is not possible to include quotes in a DOS command whose output is to be
captured
PFE does not disregard a click in a child window if another app is current
Vertical scroll bars are not updated in duplicated windows showing a file when
the current window is changed
[PFE32] When an application is launched with the Execute Launch Windows Tool
or Execute Launch Application commands, and the application subsequently
starts one of the common File Open dialogs, the directory shown will be
the directory that the original PFE application is running in, not the one
that was specified in the dialog and actually is the current dialog.
An Edit Select All followed by an Edit Cut on files of a sensitive size (?)
will cause a UAE when the file is closed
Loading a file containing a line longer than 32K will cause PFE to hang
Menu help is triggered for the system menu when the mouse is clicked in any
non-client area of the frame window
The Key Map dialog can claim that commands that have no menu item nevertheless
have keys in their menu strings
Brace matching when language type is C and the caret is in a preprocessor
directive should work, but within that line only, instead of doing nothing
If a screen area needing a redraw has an edge lying exactly on one of the
shading lines within the status bar, the shading line is not repainted
Mailing an unnamed file results in the title of the attachment icon being
garbage
If an undo of a delete for a large amount of text fails because the size is
too large, a GPF may occur when the file is closed or saved
If PFE was exited while maximized, it will not respect a "Run Minimized"
launch flag when next started from Program Manager
When no files are open, menu accelerators such as Alt+F that are not otherwise
mapped to PFE commands do not function if some files were previously open and
other mapped keys had been used
Ctrl+F4 and Ctrl+F6 do not work if the current window is iconic
Relative file names including "." and ".." given on the command line are not
correctly normalised
If the key mapping dialog is started, and an unmapped command is selected, the
Add button is not enabled if an unmapped key is then selected
-------------------------------------------------------------------------------
Reported bugs that cannot be duplicated
---------------------------------------
[A number of bugs seem to occur on some systems, but cannot be made to appear
on my development system. If you can supply insights or evidence, please get
in touch!]
Loading a file containing control characters causes either a UAE or a locked
system
Clicking on a file name in the list of the Open Existing File dialog does not
move the file name to the edit control on systems running with Italian language
drivers (probably a Windows bug)
Current directory is lost if the File Open dialogs change drives.
With no mouse present, selecting Apply and then Save in the "Default File Modes"
dialog freezes PFE until it's reactivated from Task Manager
With a 1024x768 screen driver, the status bar is clipped on the left side, and
it's not possible to position the cursor to the furthest left side of a
maximized text window
On some systems, the two rightmost pixel columns of toolbar bitmaps are not
drawn the first time the bitmaps are shown
UAE when file is dropped from File Manager and PFE is an icon
Share Violations when the work file holding output from a DOS command is opened
All text windows are cleared and redrawn every time PFE is given control after
using another application
Garbled printer output sending to a printer on a Pathworks network
On some systems (using Novell drivers?) PFE will not open files named on the
command line
After a paste operation that replaces a selection, extending the selection with
the keyboard can show the selection starting at the beginning of the pasted
text instead of the end
-------------------------------------------------------------------------------
Things To Be Done
-----------------
[This list details features that are intended to appear in the version 1 full
release. Depending on many factors it may not be possible to implement all of
the items here for that release - but they should all appear in due course]
