                         Programmer's File Editor
                      History of Development Changes
                      ------------------------------

[Note: Not all the versions whose numbers appear in the list below have
       been released publicly]


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
--------------------------------------------

Loading a file containing control characters causes either a UAE or a locked
system

The toolbar paste button is not updated correctly if another application is
activated and changes the clipboard contents

If a search locates a matching string that is to the left of the visible area
of the file, the window scrolls only far enough to show the caret; for a
forward search this leaves the target string not visible

When an area is deleted from one window, any other window showing the same file
will have its caret column position incorrectly adjusted if the caret is
within or below the area

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

In general selection dragging behaviour with the mouse outside the window needs
some improving. When the cursor is to left or right of the window tracking
should not be timer based

The method of checking for termination of a DOS command usually results in a
call to GetModuleUsage with an invalid module handle. The code needs to be
replaced with something using ToolHelp

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

When dragging, caret should go to left or right of window in a single
operation when cursor goes off past left or right borders

Most dialogs do not have system boxes

On slower machines, the screen does not update often enough to handle auto-
repeating a key

Changing the screen font to a larger type face can result in the caret no
longer being visible in the window

Duplicate windows should have ":sequencenumber" appended to their titles

There is no way to insert special characters such as ESCAPE into a file

Cursor should change to hourglass when cutting text

When MDI child is to be opened maximized, the initial state where it is shown
restored should be suppressed

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

Random UAEs when pasting large(?) blocks; Dr Watson logs show the break in
module 28 (space.o); a pointer to an SNODE block is NULL



------------------------------------------------------------------------------------

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]

Implement Undo

Replace the code that passes filenames from one instance to another with a
version that does so in one operation and hence is immune to DDE timeouts

Abolish restrictions on line length and make horizontal scroll bar handling
sensitive to the actual data visible

File|SaveAll option

Ability to indent/undent a range of lines

Add ability to define multiple keyboard macros, with load and save

Improve intelligence of text redrawing to avoid flicker in overstrike mode
and when updating the position in the status bar

Use common dialogs for Find and Replace

Implement double-click and drag to extend selection by words

Change the mouse cursor shape over selections to give a cue that drag and
drop is possible

Allow search on regular expressions

Implement line wrapping and paragraph reformatting

Resize the tool bar buttons to appear roughly the same physical size for all
screen resolutions

Implement save-with-backup and periodic-auto-save features

Record tool bar actions in keyboard macros

Make the line number area resizable by dragging the left border

Provide visual feedback when dragging the tool bar about

Hide the mouse cursor while the user is typing

When a file name is changed (by File|SaveAs or File|Name) the file and window
modes should alter to match the new file type

Ability to automatically move to the end of command output windows

Ini file option to allow PageUp/PageDown to work in units of half a window

Ability to mail files via MAPI-compliant mail systems

Full rewrite of the help file to make it actually useful

Allow current file name to automatically be substituted in DOS commands

Generate 32-bit version for Windows/NT

Allow multiple instances to run if required (currently only the fact that DOS
commands must run single-threaded prevents this)

Use the selected text as the default search string when searching

When a file is renamed by File|Name, PFE should check on saving whether the
file exists, and prompt for confirmation if it does

Add adjustable right margin line to indicate a specific column width

Auto-indenting should be done if a line is split, or a newline is inserted
within it

Remember position of floating toolbar between sessions

When dragging-and-dropping, use Shift down to force a copy regardless of the
ini file settings regarding control key usage


------------------------------------------------------------------------------------

Long Term Developments
----------------------

[Features here are regarded generally as Good Things, and may well be included
 in later releases. They will not be implemented for version 1]

User configurable tool bar and menu

Script language

More sophisticated language support driven by external language-aware DLLs to
perform syntax colouring, etc

Optional project management system

Support for group working under Windows for Workgroups

Ability to invoke help based on the items selected in a window

Text folding and bookmarks




------------------------------------------------------------------------------
Thanks to all the beta testers whose bug reports, comments and suggestions
have gone towards the development of PFE
