	This is the documentation for version 1.6 of PlainText. Be sure to read 
the section ÔFat BinaryÕ that appears later in this document.
	
	You should make a copy of this file and save it somewhere with a different
name. One way of doing this is to select the ÒSave a CopyÓ item from the
File Menu. Name the copy ÒOriginal PlainText WorksheetÓ or some such.

File Menu
	This is standard Mac stuff. PlainText will open any text file. Printing is
pretty ordinary. There is no way to change print margins or lines per page.
A short vertical line appears at the top of every text window which indicates 
the recommended right margin. Text wrapped to this width will be centered on 
the printed page. PlainText prints the page number at the bottom of every page.
	
	If you hold the option key down while selecting the Open menu item, then
all files, not just text files, are displayed and can be opened. Files opened 
in this way are read only. You can copy data from them to the clipboard but 
not change them in any way.

	The ÒSaveÓ menu item is activated when a file has been changed by adding or
removing characters. The term ÒdirtyÓ is commonly used to describe text files
in this state. Non-editing changes, such as changing the font or adding a mark
do not dirty a file. However, all such changes, even scroll position and
selection range, are always saved to disk when you close a file. So, donÕt be
surprised by disk activity when you close a file in which you have made no text
changes.

	The ÒSaveÓ menu item is also active when a non-PlainText file is opened and
that file does not contain the resource that PlainText, and many other 
Macintosh text editors, use to store window size, selection, and several other
parameters. Selecting ÒSaveÓ will cause that resource to be created.

Edit Menu
	The Undo function provides the one level of undo that you expect with a
Macintosh application. Likewise the Cut, Copy, Paste, and Clear routines work
in the standard Macintosh fashion. However, their action can be changed by the
ÒEdit ColumnsÓ menu item. Clicking on this item toggles column editing on or 
off. Column editing is only allowed when a fixed font such as Monaco or Courier 
is in use. The ÒEdit ColumnsÓ menu item is not even enabled when a proportional
font is being used.

	With column editing enabled, cutting and clearing text operates on every
line in the text file, cutting or clearing a vertical column of characters
corresponding to the selection range. This column is shown by a rectanglar
dotted outline. Note that this column selection range disappears when the 
normal selection range extends across more than one line. Column pasting will
insert the columns contained in the clipboard into every line, along the 
vertical column indicated by the selection range. 

	ÒShift RightÓ and ÒShift LeftÓ add or remove one tab on each line or, 
when word wrap is on, each paragraph within the selection region. At the 
same time, it converts all space runs to the corresponding number of tabs.
ÒAlignÓ aligns all subsequent lines to the first line in the selection
region.

	ÒNo WorksheetÓ will close the worksheet window and set PlainText to not
open a worksheet window in the future. It is reversed by the ÒUse WorksheetÓ
menu item which becomes an option when there is no worksheet. When in the
No-Worksheet mode, PlainText will open a blank untitled window, like most Mac
applications, when lauched. The Format dialog of the Edit Menu is where you
select fonts and font size, turn wordwrapping on or off (ON is the default),
select tab width, and show or not show invisible characters. These settings are
remembered for each document and retained between launches. (Naturally, this is
a Mac.)

	The ÒFormatÉÓ menu item calls a dialog for changing text font, text size,
and certain preferences. The ÒShow InvisiblesÓ check box prints ÔÀÕ for all
non-printing characters, ÔÆÕ for tabs, ÔÂÕ for carriage returns, and Ô×Õ
for spaces. Automatic word wrap can be turned off or on and made to occur
when text exceeds the width of the textÕs window or a particular number of
characters (Line Length). This line length parameter is also used for the
ÒHard Wrap to LengthÓ item in the Convert Menu. The ÒAuto IndentÓ feature
will look at the preceding line, when word wrap is off, or paragraph, when
word wrap is on, and indent each new line to align with it. Clicking the
okay button (or typing the return or enter key) applies those settings to
the front window. Clicking the cancel button (or typing escape or
command-period) cancels the dialog and does not make any changes to the
front window. Clicking on the ÒAll FilesÓ button applies the settings to
the front window and saves them as default settings that will be applied to
all new windows and any foreign file that has not been previously opened by
PlainText, MPW, or Alpha.

	Note that ÒShow InvisiblesÓ is also a menu item that is equivalent in
to clicking the ÒShow InvisiblesÓ check box in the Format dialog.

Find Menu
	ÒFind, ReplaceÉÓ implement the pretty standard and pretty intuitive search
and replace functions for text windows. The search string can be a
selection expression, that is, an expression that contains wildcards. (See
the ÒSelection ExpressionÓ section, below. Try a search using *menu as the
selection expression. Choose ÒFindÉÓ and type Ò*menuÓ (without the quotes)
and click the ÒSelection ExpressionÓ radio button. Now click the Find
button (or hit the return key). See how a line containing ÒmenuÓ has been
found? Command-G repeats the search.

	If the selection expression is a number, it is interpreted as a line
number. Try 111 as a selection expression.

	This line, the 111th in this window, will be selected.

	If you hold down the shift key when you choose any of the Find menu items,
then the search will be in the reverse direction. This is handiest when
used in conjunction with the keyboard equivalents command-H and command-G.

	ÒCut Lines ContainingÉÓ and ÒCopy Lines ContainingÉÓ allow you to cut or 
copy all lines, or paragraphs if word wrap is on, to the clipboard. Note that
there are command line equivalents, Òcutline and ÒcopylinesÓ (see below).

Mark Menu
	The Mark Menu handles two separate types of actions that can be used to
mark text. (1) Bookmarks can be set at points in the text that you want to be
able to jump back to. (2) Line numbers or other kinds of textual labelling 
can be added to or removed from the begining of each line or paragraph. 
	
	The line numbering functions allow you to add or strip line or paragraph
numbers from your text. Interesting enough, it is also useful for adding or
removing characters to comment out blocks of computure code. Study the 
ÒNumbering ParametersÉÓ dialog. It does the simple things, like allowing you 
to specify starting number and the numbering interval. It also allows you to 
specify a prefix and suffix string to immediately precede and immediately 
follow each line number and it allows three numbering modes: Arabic numerals, 
Roman numberals (either upper or lower case), or an Alphabetic sequence (either
upper or lower case, such as A, B, C, É z, aa, ab, etc.). To switch numbering 
style either delete all the characters of the ÒStarting NumberÓ dialog item and
type in a new entry in the style you want (e.g. ÒxivÓ) or repeatedly click on 
the small style button to the right of the ÒStarting NumberÓ dialog item.

	Marks are like bookmarks that you can place in a text file so that you 
can recall previous selections. When you select a mark from the Mark Menu, 
the text corresponding to that mark is selected and the window scrolls to 
show it. You can add new marks with the Mark menu item and remove them with
Unmark. You can alphabetize the order in which marks are displayed in the
Mark Menu by selecting the Alphabetize menu item. Selecting it again restores 
the original order. Look at the Marks that I have made for this file by 
opening the Marks Menu.

Window Menu
	Stack and Tile Windows resize the windows in either a stack or tiled so
that each window is visible on the screen. The remaining menu items are a 
catalog of open windows. The menu item for the front window is checked. The 
target window is indicated by the bullet symbol (¥). Windows whose changes 
have not yet been saved to disk are underlined.

Convert Menu
	This is a set of useful functions for converting or otherwise editing
text. These functions have been requested by users or was selected from
those I found myself using many times a day in Vantage, the desk accessory
editor that I used for years. The big, full-featured editors, like Pete
KeleherÕs Alpha and BBEdit, by Rich Siegel, have these features, plus many
more, as well.

	Strip Linefeeds is the way to convert an MS/DOS text file to the Mac
convention.

	Strip Controls removes all characters with an Ascii code of 31 or less,
except carriage returns and tabs.

	Form Paragraphs and Straight to Curly Quotes do what they say they do and
are indispensible for preparing text for pasting into a word processor. 
	Hard Wrap to Window and Curly to Straight quotes reverses those steps,
such as when you want to prepare text for e-mail.

	The two Hard Wrap functions insert hard carriage returns at line ends,
where a line end is defined either by the width of the window (Hard Wrap to
Window) of the line length parameter set in the Format Dialog (Hard Wrap to
Length).

	The ÒStrip Line NumbersÓ function will remove any leading digits in a 
text file, and leading characters that conform to the currently selected
numbering convention (Arabac, Roman, or Alpha) and concatinations of the
latter with the prefix and suffix strings.

	The last two menu items will sort lines or paragraphs in either ascending
or descending order. Marks remain correctly attached to the text they reference.

Typing Behavior

	Besides being fast and able to handle even very large files, PlainText has
these built-in features:

	1.	Double-clicking selects a whole word. Note that double-clicking
		the space after a word selects the preceeding word and the space.
		This is a bug that is close enough to being a feature that I am 
		not fixing it.
	2.	Triple-clicking selects a whole line.
	3.	Double clicking on or just before a bracket or parenthesis (i.e. 
		Ò[Ó, Ò{Ó, etc.) causes all the text between the bracket or 
		parenthesis and its matching bracket or parenthesis to become 
		selected.
	4.	Cutting, pasting, and undoing are fully implemented.
	5.	The arrow keys work to move the insertion point or selection (hold
		the shift key down) in the expected ways.
	6.	Command-option-uparrow moves the insertion point to the top of the
		file. Command-option-downarrow does the opposite. Holding the shift
		key down while doing either of these extends the selection to either
		the top or bottom of the document.
	7.	Command-right arrow moves the insertion point to the end of the 
		current line. Option-right arrow moves the cursor by words. The left
		arrow combinations work in the same way, of course, and holding the
		shift key down with any of these combinations extends the selection.
		This is the standard Macintosh use of the arrow keys.
	8.	It is a command-line interpreter in its own right. Simply type a 
		command that PlainText understands and then hit the enter (not
		return) key. This will work in any text window.
 
		The following commands can be executed from any text window: 
		ls (same as dir in DOS), cd (change directory), chcre (change file
		creator), chtyp (change file type, copylines, cutlines, file, open,
		find, line. ÒOpenÓ opens the named file and makes it the front window.
		File is similar except the window is made the target window (second
		from front). Òline nÓ selects selects the nth line of the target
		window (n is a number. ÒFind expÓ searchs the target window for the
		string Òexp.Ó If there are embedded spaces within the search string,
		enclose it in double (") or single (') quotes. Enclosing the search
		string with the right slash (/) will cause it to be interpreted as
		a regular expression. (See ÒSelection Expressions,Ó below.) The same
		rules apply for the search strings used for the "copylines" and
		"cutlines" commands. If there is a standard set of lines, like
		e-mail headers, that you need to remove from files on a regular
		basis, save a list of appropriate cutlines commands in your work-
		sheet.

		In summary, hitting the enter key causes the current line or current 
		selection, whichever is smaller, to be interpreted as a command line.

		Commands implemented:

			cat f,f...	 An Untitled window is opened and each of the files
						 in the file list (f,f,...) is concatenated into it.
						 The file names can be separated by whitespace or
						 commas.
			cd			 Change default directory (folder). Note, the Mac 
						 file system uses the colon to designate the present 
						 or higher folders. Thus Òcd ::Ó changes the default
						 directory one level up.
			chcre		 Change a fileÕs creator. For example, 
						 chcre ÔMRPHÕ ÔCurrent FileÕ makes PlainText the
						 creator of the file named ÔCurrent File.Õ
			chtyp		 Change the file type of a file, using the same
						 syntax (chtyp type filename) as chcre.
			copylines ss copy all lines containing the search string, ss.
			cutlines ss  cut all lines containing the search string
			dump		 performs a hex dump of the target windowÕs selection
						  range.
			fat2PPC ff	 if ff is the name of a fat binary application, then 
						  powerPC version is created, named ff.PPC.
			fat268k ff   strips off the PowerPC code to make a fat binary a
						  68K Mac version.
			file		 Open a file and make it the target
			find ss		 Find a string in the target window
			ls			 List a directoryÕs contents
			ls -l		 Give a full listing of a directoryÕs contents
			line nn		 Select line nn in the target window
			open ff		 Open file named ff.
			p nn		 Selects the nnth paragraph of the target window.
			pwd			 Print current directory.
			stats		 Prints the statistics of the target window
			toolserver	 Launch ToolServer and use it for command-line
						  interpretation.

Target Window
	Note that the ÒlineÓ and ÒfindÓ comands operate on the TARGET window. The
target window is the window behind the front-most window.

Large Files
	PlainText must load its text files entirely into memory. If you get an
out-of-memory error message when trying to open a very large file, just
increase the partition (in the FinderÕs Get-Info box for PlainText) to be
larger than the file being opened. In System 7, turn on virtual memory if
necessary.

Selection Expressions

	PlainText implements a subset of the regular expressions as implemented in
unix and related to those implemented in MPW. The search string is interpreted
as a regular expresson when the  ÒSelection ExpressionÓ radio button is 
selected in the ÒFind and ReplaceÓ or ÒCut/Copy Lines ContainingÓ dialogs.
	
	When ToolServer is being used, the full set of ToolServer selection 
expressions is of course implemented in command-line commands.

The following is the native PlainText implementation:

Wildcards
	* and Å (option-x) select any text from the beginning of a line or to 
	the end of a line.
	? selects any single character.
Sets
	Characters appearing between square brackets represents a set, any one 
	of which will be a valid match. Sets can include ranges. A range is 
	represented by two characters separated by a hyphen. They will match 
	any character with an ascii code within the range. Thus [0-9] (or [0-9])
	will match any digit. [a-z] will match any lower-case letter. If the 
	ÒCase SensistiveÓ check box is off, the [a-z] is the same as [a-zA-Z]. 
Repeats
	The plus sign (+) following any character or a set will match a sequence 
	of one or more of the preceeding set or character.
Special characters and escape
	Any ascii code can be represented as a two-digit hex following the dollar
	sign ($) or itÕs equivalent on your international keyboard. Thus, $20 is 
	the space character and $0C is the formfeed character.
	
	The backslash character is used to represent special characters and to 
	make interpretation of any following character literal.
	
		\t		tab 
		\r		return ($0D)
		\l		linefeed ($0A)
		\f		formfeed ($0C)
		
	and
		\\		backslash
		\[		right square bracket, etc.
		
	Hex ($00) and backslash character codes are the only elements of the 
	selection expression syntax that can appear in the Replace string of 
	the ÒFind and ReplaceÓ dialog and then only if the ÒSelection ExpressionÓ 
	radio button is selected.
	
Fat Binary

	Versions after 1.4 are distributed as a fat binary. That means they 
contain both Motorola 680x0 and PowerPC native code. With two sets of binary
code, the fat binary file occupies about 140K more disk space than a PowerPC 
or 680x0-specific version. If this is a handicap for you, you can strip either
the PowerPC native code or the 680x0 native code out, using the new command-
line commands fat2PPC or fat268k. Make a copy of PlainText and then type, for
example, fat268k 'PlainText copy' <enter>. A file, named 'PlainText copy.68k',
which has no PowerPC code, will appear on your disk. Rename it as you please.

ToolServer

	PlainText will send all command-line commands to ToolServer after the 
ÔToolServerÕ command is given and ToolServer is available in your system for
launching. At its first use, PlainText will ask you to find ToolServer. After
that, it remembers the location between launches.

		   cursor is disabled.
		 In large files, the blinking cursor would be displayed as a long
		   vertical line when the window was scrolled more than 32K pixels

1.2c:	 Marks now updated after large selections of text deleted.
		 Will now print invisible characters and tabs.
1.2d:	 Added page numbers to printed page.
1.2.1:	 First non-beta release to public servers, i.e. Info-Mac.
	 	 Restored ÒFile open in another applicationÓ alert.
	 	 In word wrap, adding or deleting text that caused rewrapping of
	 	   paragraphs with more than 32 lines used to blank part of the 
	 	   window above the changed text. Fixed.
1.2.2	 ÒTile WindowsÓ formally tiled the Worksheet window and not the 
		   last text window. It now excludes the Worksheet from tiling.
		 Added support for a Preferences file for storing defaults.
		 Added the stats command-line option.
		 Added a four-pixel tick mark at the top of each window to indicate
		   the printed page width, minus 1Ó right and left margins.
		 Tabs now aligned when typing in the middle of a line.
1.2.3	 1.2.2 introduced a bug that caused characters typed at the beginning
		   of an empty window to either not be draw are drawn in the wrong
		   position.
1.2.4	 There was still misalignment when tabs were typed. Fixed.
		 Added chtyp and chcre commands.
		 The ÒFind SelectionÓ menu item now activated for locked windows.
		 Added the ÒStrip ControlsÓ menu item.
1.2.5	 Fixed curor misplacement when typing returns at the end of a text 
		   file with AutoIndent on.
		 Files without resource forks would not open. I think this bug also
		   caused drag-and-drop to fail for these files.
		 Fixed the sometimes garbled text in the confirmation dialogs.
		 Cut and paste now works in the Find and Replace dialogs.
		 ÒRevert to SavedÓ previously caused a scrolling error.
1.2.6	 Deleting an entire file would not delete the fileÕs marks. Fixed.
		 Cursor initialized with each activate event.
1.2.7	 ÒSave AsÉÓ and ÒSave A CopyÉÓ will now replace an existing file in
		   the proper way.
		 Added ÒPÓ as the keyboard equivalent for printing.
1.2.8	 Zooming is now to the best size for a text window and not full screen.
		 All other Apple guidelines for zooming now conformed to.
		 Scroll bars no longer drawn twice in zooming.
		 Stats command now works at all times.
		 New window opened to ideal size.
1.2.9	 Fixed zooming bug introduced in 1.2.8 that caused crashes in System 6.
		 Several obscure coding errors turned up in using the MetroWerks
		   compiler. These were probably never seen by users.
1.2.9a	 Further fix of zooming bug. (Thanks to Bruce Craven and Joel Martin.)
1.3		 Replace now doesnÕt insert an extra character.
		 Dialog for find and replace now modeless (thanks to David Wright).
		 Strip Controls no longer deletes accented characters.
	 	 The line length parameter is saved.
	 	 Tabs to Spaces used to skip every other sequential tab.
	 	 Added ÒCut/Copy Lines ContainingÓ dialog.
1.3.1	 Fixed version 1.3 crashes when closing the ÒUnmarkÉÓ dialog.
		 Implemented and fixed the full set of selection expressions.
1.3.2	 Prior to this, the Find function would search past the end of text. 
		   In some cases, this caused extra replacements in global search and
		   replace. That was benign. However, it caused fatal freezes in the
		   ÒCut Lines ContainingÓ function.
1.3.3	 Added "cutlines" and "copylines" command-line equivalents. 
		 Command-line searchs now use the right slash (/) to indicate that
		   the search string is a regular expression.
		 Added delay to page scrolling.
		 Cut and paste in Standard File dialog now uses proper scrap.
1.3.4	 Special characters (e.g. \t or \r) in the Replace string were ignored
		   if not followed by one or more ordinary characters. Fixed.
		 When reopening a long document, the place in view was not the same as
		   the one when the document was closed. Fixed.
		 An already open document window is now brought to the front when 
		   its icon is double clicked or it is selected in the ÒOpenÉÓ dialog.
		 When not using the Worksheet option, PlainText now opens a blank 
		   untitled window upon launch.
1.3.5	 Fixed bug that made wordwrapped documents open viewing a page or so
		   higher than when closed. This bug had also been causing wordwrapping
		   to be calculated twice when a document was opened.
		 Fixed error in opening foreign text files in which selection 
		   highliting is wrong, or there are even crashes when shift-clicking
		   to select a region.
1.3.6	 Previously, expression searches ignored the last character in a file.
		   Fixing this bug involved a general improvement of memory management
		   for PlainText and its TextEdit core code (TE32K.c).
		 Changing to ÒWord Wrap to LengthÓ from no word-wrapping previously 
		   caused an error in the horizontal scroll bar. (It was either absent
		   or set to the wrong values.)
		 Find now scrolls to position found text at the upper 1/3 of a window.
		 Read-only files now do not change the resource fork of file they open.
		 Also fixed some other logic errors that allowed read-only files to be
		   modified.
		 Scrap now converted at program launch.
1.3.7	 Added more error checking when opening the worksheet window.
		 ÒSave AsÉÓ and ÒSave A CopyÉÓ still had a bug. New windows were not
		   replacing existing files.
1.3.8	 Fixed bug in which a new blank worksheet was not being created when
		   none existed before.
		 ÒSave AsÉÓ and ÒSave A CopyÉÓ still had a bug. The fix in 1.3.7 re-
		   introduced the bug, fixed in 1.2.7, in which a file would not re-
		   place itself.
1.3.9	 Supports hex characters in range searches (i.e. [$01-$1F]).
		 Regular expression searches now work in 24-bit mode.
		 Shift-click crashes that occured in new documents now fixed.
		 Arrow cursor now obscured when typing. The underlying improvements in
		   cursor handling probably fixed the conditions that sometimes made
		   PlainText very sluggish.
		 Active area of text windows enlarged on the left by three pixels. This 
		   eases clicking to select the beginning of a line.
		 Scrap now passed to ÒCut Lines ContianingÓ dialog.
		 Final condition where last-modified date changed with foreign text 
		   files removed.
	 	 The line length parameter is now properly saved when the ÒAll FilesÓ
	 	   button in the ÒFormatÉÓ dialog is clicked.
	 	 Finds from the ÒFind and ReplaceÓ dialog now briefly hilite the found
	 	   selection. (Thanks to Steve Witt for this and other ideas.)
1.4		 1.3.9 did not switch to arrow cursor when last document closed and for
		   some modal dialogs.
		 Compiled fat binary version.
		 Added defatting commands.
		 Placed command-line commands in a STR# resource.
		 Commands are no longer case sensitive.

		   crashes reported when a key is typed, as in System 6.

		   causing crashes. This routine will be rewritten.
		 Changed Menu labels for conversion routines.

		   would cause a crass and non-dirty files were not written to disk.

Known bugs
	 Unbroken text (i.e. containing no spaces) is wrapped to window width.
	 Part of the Numbering ParametersÉ not properly redrawn on some Mac models.
	 Some fonts have letters that extend to the right of the insertion point
	   cursor. These can cause stray pixels to be drawn on the screen.
	 With Show Invisibles on, inserting CR at beginning of text is displayed
	   as if on 2nd line. The first line is not scrolled. Text is okay.
	 Insertion point placement after a tab not intuitive.
	 Tabs spaced differently, in some cases, with and without invisibles.

Features to be added:
	 Floating window for display of text stats.
	 Saving a default directory
	 Support of a complete AppleEvent suite and rationalization.
