+
+
+The editor 'ee' (easy editor) is intended to be a simple, easy to use
+terminal-based screen oriented editor that requires no instruction to
+use. Its primary use would be for people who are new to computers, or who
+use computers only for things like e-mail.
+
+ee's simplified interface is highlighted by the use of pop-up menus which
+make it possible for users to carry out tasks without the need to
+remember commands. An information window at the top of the screen shows
+the user the operations available with control-keys.
+
+ee allows users to use full eight-bit characters. If the host system has
+the capabilities, ee can use message catalogs, which would allow users to
+translate the message catalog into other languages which use eight-bit
+characters. See the file ee.i18n.guide for more details.
+
+ee relies on the virtual memory abilities of the platform it is running on
+and does not have its own memory management capabilities.
+
+I am releasing ee because I hate to see new users and non-computer types
+get frustrated by vi, and would like to see more intuitive interfaces for
+basic tools (both character-based and graphical) become more pervasive.
+Terminal capabilities and communication speeds have evolved considerably
+since the time in which vi's interface was created, allowing much more
+intuitive interfaces to be used. Since character-based I/O won't be
+completely replaced by graphical user interfaces for at least a few more
+years, I'd like to do what I can to make using computers with less
+glamorous interfaces as easy to use as possible. If terminal interfaces
+are still used in ten years, I hope neophytes won't still be stuck with
+only vi.
+
+For a text editor to be easy to use requires a certain set of abilities. In
+order for ee to work, a terminal must have the ability to position the cursor
+on the screen, and should have arrow keys that send unique sequences
+(multiple characters, the first character is an "escape", octal code
+'\033'). All of this information needs to be in a database called "terminfo"
+(System V implementations) or "termcap" (usually used for BSD systems). In
+case the arrow keys do not transmit unique sequences, motion operations are
+mapped to control keys as well, but this at least partially defeats the
+purpose. The curses package is used to handle the I/O which deals with the
+terminal's capabilities.
+
+While ee is based on curses, I have included here the source code to
+new_curse, a subset of curses developed for use with ee. 'curses' often
+will have a defect that reduces the usefulness of the editor relying upon
+it. This is unused by the FreeBSD version of ee (the existing ncurses
+library works just fine) but is included in the doc subdirectory for
+reference purposes should anyone wish to port ee to a platform for
+which the existing curses libraries are insufficient.
+
+The files doc/new_curse.[ch] contain a subset of the 'curses' library
+used by applications to handle screen output. Unfortunately, curses
+varies from system to system, so I developed new_curse to provide
+consistent behavior across systems. It works on both SystemV and BSD
+systems, and while it can sometimes be slower than other curses packages,
+it will get the information on the screen painted correctly more often
+than vendor supplied curses. Again, FreeBSD does not have this problem
+but you may find it useful on other platforms.
+
+If you experience problems with data being displayed improperly, check
+your terminal configuration, especially if you're using a terminal
+emulator, and make sure that you are using the right terminfo entry
+before rummaging through code. Terminfo entries often contain
+inaccuracies, or incomplete information, or may not totally match the
+terminal or emulator the terminal information is being used with.
+Complaints that ee isn't working quite right often end up being something
+else (like the terminal emulator being used).
+
+Both ee and new_curse were developed using K&R C (also known as "classic
+C"), but it can also be compiled with ANSI C. You should be able to
+build ee by simply typing "make".
+
+ee is the result of several conflicting design goals. While I know that it
+solves the problems of some users, I also have no doubt that some will decry
+its lack of more features. I will settle for knowing that ee does fulfill
+the needs of a minority (but still large number) of users. The goals of ee
+are:
+
+ 1. To be so easy to use as to require no instruction.
+ 2. To be easy to compile and, if necessary, port to new platforms
+ by people with relatively little knowledge of C and UNIX.
+ 3. To have a minimum number of files to be dealt with, for compile
+ and installation.
+ 4. To have enough functionality to be useful to a large number of
+ people.

+ The "Artistic License"
+
+ Preamble
+
+The intent of this document is to state the conditions under which a
+Package may be copied, such that the Copyright Holder maintains some
+semblance of artistic control over the development of the package,
+while giving the users of the package the right to use and distribute
+the Package in a more-or-less customary fashion, plus the right to make
+reasonable modifications.
+
+Definitions:
+
+ "Package" refers to the collection of files distributed by the
+ Copyright Holder, and derivatives of that collection of files
+ created through textual modification.
+
+ "Standard Version" refers to such a Package if it has not been
+ modified, or has been modified in accordance with the wishes
+ of the Copyright Holder.
+
+ "Copyright Holder" is whoever is named in the copyright or
+ copyrights for the package.
+
+ "You" is you, if you're thinking about copying or distributing
+ this Package.
+
+ "Reasonable copying fee" is whatever you can justify on the
+ basis of media cost, duplication charges, time of people involved,
+ and so on. (You will not be required to justify it to the
+ Copyright Holder, but only to the computing community at large
+ as a market that must bear the fee.)
+
+ "Freely Available" means that no fee is charged for the item
+ itself, though there may be fees involved in handling the item.
+ It also means that recipients of the item may redistribute it
+ under the same conditions they received it.
+
+1. You may make and give away verbatim copies of the source form of the
+Standard Version of this Package without restriction, provided that you
+duplicate all of the original copyright notices and associated disclaimers.
+
+2. You may apply bug fixes, portability fixes and other modifications
+derived from the Public Domain or from the Copyright Holder. A Package
+modified in such a way shall still be considered the Standard Version.
+
+3. You may otherwise modify your copy of this Package in any way, provided
+that you insert a prominent notice in each changed file stating how and
+when you changed that file, and provided that you do at least ONE of the
+following:
+
+ a) place your modifications in the Public Domain or otherwise make them
+ Freely Available, such as by posting said modifications to Usenet or
+ an equivalent medium, or placing the modifications on a major archive
+ site such as uunet.uu.net, or by allowing the Copyright Holder to include
+ your modifications in the Standard Version of the Package.
+
+ b) use the modified Package only within your corporation or organization.
+
+ c) rename any non-standard executables so the names do not conflict
+ with standard executables, which must also be provided, and provide
+ a separate manual page for each non-standard executable that clearly
+ documents how it differs from the Standard Version.
+
+ d) make other distribution arrangements with the Copyright Holder.
+
+4. You may distribute the programs of this Package in object code or
+executable form, provided that you do at least ONE of the following:
+
+ a) distribute a Standard Version of the executables and library files,
+ together with instructions (in the manual page or equivalent) on where
+ to get the Standard Version.
+
+ b) accompany the distribution with the machine-readable source of
+ the Package with your modifications.
+
+ c) accompany any non-standard executables with their corresponding
+ Standard Version executables, giving the non-standard executables
+ non-standard names, and clearly documenting the differences in manual
+ pages (or equivalent), together with instructions on where to get
+ the Standard Version.
+
+ d) make other distribution arrangements with the Copyright Holder.
+
+5. You may charge a reasonable copying fee for any distribution of this
+Package. You may charge any fee you choose for support of this Package.
+You may not charge a fee for this Package itself. However,
+you may distribute this Package in aggregate with other (possibly
+commercial) programs as part of a larger (possibly commercial) software
+distribution provided that you do not advertise this Package as a
+product of your own.
+
+6. The scripts and library files supplied as input to or produced as
+output from the programs of this Package do not automatically fall
+under the copyright of this Package, but belong to whomever generated
+them, and may be sold commercially, and may be aggregated with this
+Package.
+
+7. C subroutines supplied by you and linked into this Package in order
+to emulate subroutines and variables of the language defined by this
+Package shall not be considered part of this Package, but are the
+equivalent of input as in Paragraph 6, provided these subroutines do
+not change the language in any way that would cause it to fail the
+regression tests for the language.
+
+8. The name of the Copyright Holder may not be used to endorse or promote
+products derived from this software without specific prior written permission.
+
+9. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
+IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
+WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

+Easy Editor ("ee") provides the ability to translate the messages displayed to
+the user and the commands entered. This is done via message catalogs,
+following X/Open standards. ee only supports eight bit characters.
+
+(The name ee.i18n.guide is for "ee internationalization guide". The i18n
+abbreviation is used because there are 18 characters between the first

+statements, which are of the form "%s", or "%d", these must be preserved in
+the translation, or the correct information will not be displayed. For those
+strings containing multiple formatting codes, the order of each item must be

+154 - 158 info window entries for emacs key bindings info
+159 string for turning on emacs key bindings in the init file
+160 string for turning off emacs key bindings in the init file
+
+Care should be taken when translating commands and initialization keywords
+because the algorithm used for detecting uniqueness of entered commands
+will not be able to distinguish words that are not unique before the end
+of the shorter word, for example, it would not be able to distinguish the
+command 'abcd' from 'abcde'.
+
+After translating the messages, use the 'gencat' command to create the compiled
+catalog used when running the software. The standard syntax would be:
+
+ gencat ee.cat ee.msg
+
+Where ee.msg is the file containing the translations, and ee.cat is the
+compiled catalog. If the file ee.cat does not exist, it will be created.
+Check the documentation for your system for proper syntax.
+
+Message catalog placement varies from system to system. A common location
+for message catalogs is in /usr/lib/nls. In this directory are
+directories with the names of other languages. The default language is
+'C'. There is also an environment variable, named NLSPATH used to
+determine where message catalogs can be found. This variable is similar
+to the PATH variable used for commands, but with some differences. The
+NLSPATH variable must have the ability to handle different names for
+languages and the catalog files, so it has field descriptors for these. A
+typical setting for NLSPATH could be:
+
+ NLSPATH=/usr/lib/nls/%L/%N.cat:/usr/local/lib/nls/%L/%N.cat
+
+Where "%L" is the field descriptor for the language (obtained from the
+LANG environment variable) and "%N" is the name of the file (with the
+".cat" appended by the path variable, it is not passed from the requesting
+program). The colon (:) is used to separate paths, so in the above
+example there are two paths possible for message catalogs. You may wish
+to maintain catalogs for applications that are not supported by your
+system vendor in a location unique for you, and this is facilitated by the
+NLSPATH variable. Remember to set and export both the LANG and NLSPATH
+variables for each user that expects to use localization either in a
+system-wide profile or in each user's profile. See your system
+documentation for more information.
+
+The message catalog supplied with ee also uses the '$quote' directive to
+specify a quote around strings to ensure proper padding. This directive
+may not be supported on all systems, and lead to quotes being included in
+the string used in ee, which will cause incorrect behavior. If the
+'$quote' directive is not supported by your system's gencat command, edit
+the msg file to remove the leading and trailing quotation marks.

+.SH DESCRIPTION
+The command
+.I ee
+is a simple screen oriented text editor. It is always in text insertion
+mode unless there is a prompt at the bottom of the terminal, or a
+menu present (in a box in the middle of the terminal). The command
+.I ree
+is the same as
+.I ee,
+but restricted to editing the named
+file (no file operations, or shell escapes are allowed).
+.PP
+For
+.I ee
+to work properly, the environment variable
+.SM TERM
+must be set to indicate the type of terminal being used. For
+example, for an
+.SM HP 700/92
+terminal, the
+.SM TERM
+variable should be set to "70092". See your System Administrator if
+you need more information.
+.\"
+.\" options
+.\"
+.SS Options
+The following options are available from the command line:
+.PP
+.TP 4
+.B -e
+Turns off expansion of tab character to spaces.
+.TP
+.B -i
+Turns off display of information window at top of terminal.
+.TP
+.B -h
+Turns off highlighting of borders of windows and menus (improves
+performance on some terminals).
+.TP
+.B +#
+Moves the cursor to line '#' at startup.
+.br
+.\"
+.\" control keys
+.\"
+.SS "Control keys"
+To do anything other than insert text, the user must use the control
+keys (the
+.B Control
+key, represented by a "^", pressed in conjunction with an
+alphabetic key, e.g., ^a) and function keys available on the keyboard
+(such as
+.BR "Next Page" ", " "Prev Page" ,
+arrow keys, etc.).
+.PP
+Since not all terminals have function keys,
+.I ee
+has the basic cursor movement functions assigned to control keys as
+well as more intuitive keys on the keyboard when available. For
+instance, to move the cursor up, the user can use the up arrow key,
+or
+.BR ^u .
+.RS 4
+.nf
+.ta 1.4i
+.sp
+^a Prompt for the decimal value of a character to insert.
+^b Move to the bottom of the text.
+^c Get the prompt for a command.
+^d Move the cursor down.
+^e Prompt for the string to search for.
+^f Undelete the last deleted character.
+^g Move to the beginning of the line.
+^h Backspace.
+^i Tab.
+^j Insert a newline.
+^k Delete the character the cursor is sitting on.
+^l Move the cursor left.
+^m Insert a newline.
+^n Move to the next page.
+^o Move to the end of the line.
+^p Move to the previous page.
+^r Move the cursor to the right.
+^t Move to the top of the text.
+^u Move the cursor up.
+^v Undelete the last deleted word.
+^w Delete the word beginning at the cursor position.
+^x Search.
+^y Delete from the cursor position to the end of line.
+^z Undelete the last deleted line.
+^[ (ESC) Pop up menu.

+.fi
+.RE
+.sp
+.SS "EMACS keys mode"
+.PP
+Since many shells provide an Emacs mode (for cursor movement and other editing
+operations), some bindings that may be more useful for people familiar with
+those bindings have been provided. These are accessible via the
+.B settings
+menu, or via the initialization file (see below). The mappings are as follows:
+.RS
+.nf
+.ta 1.4i
+^a Move to the beginning of the line.
+^b Back 1 character.
+^c Command prompt.
+^d Delete character the cursor is sitting on.
+^e End of line.
+^f Forward 1 character.
+^g Go back 1 page.
+^h Backspace.
+^i Tab.
+^j Undelete last deleted character.
+^k Delete line.
+^l Undelete last deleted line.
+^m Insert a newline.
+^n Move to the next line.
+^o Prompt for the decimal value of a character to insert.
+^p Previous line.
+^r Restore last deleted word.
+^t Move to the top of the text.

+.\" paragraph formatting
+.\"
+.SS "Paragraph Formatting"
+.PP
+Paragraphs are defined for \fIee\fR by a block of text bounded by:
+.sp
+.RS 8
+.IP \(bu
+Begin or end of file.
+.IP \(bu
+Line with no characters, or only spaces and/or tabs.
+.IP \(bu
+Line starting with a period ('.') or right angle bracket ('>').
+.RE
+.PP
+A paragraph may be formatted two ways: explicitly by choosing the
+\fBformat paragraph\fR menu item, or by setting \fIee\fR to automatically
+format paragraphs. The automatic mode may be set via a menu, or via the
+initialization file.
+.PP
+There are three states for text operation in \fIee\fR: free-form, margins,
+and automatic formatting.
+.PP
+"Free-form" is best used for things like programming. There are no
+restrictions on the length of lines, and no formatting takes place.
+.PP
+"Margins" allows the user to type in text without having to worry about going
+beyond the right margin (the right margin may be set in the \fBsettings\fR
+menu, the default is for the margin to be the right edge of the
+terminal). This is the mode that allows the \fBformat paragraph\fR menu
+item to work.
+.PP
+"Automatic formatting" provides word-processor-like behavior. The user
+may type in text, while \fIee\fR will make sure the entire paragraph fits
+within the width of the terminal every time the user inserts a space after
+typing or deleting text. Margin observation must also be enabled in order for
+automatic formatting to occur.
+.\"
+.\" modes
+.\"
+.SS Modes
+.PP
+Although ee is a 'modeless' editor (it is in text insertion mode all the
+time), there are modes in some of the things it does. These include:
+.RS 4
+.IP "\fBtab expansion\fR"
+Tabs may be inserted as a single tab character, or replaced with spaces.
+.IP "\fBcase sensitivity\fR"
+The search operation can be sensitive to whether characters are upper- or
+lower-case, or ignore case completely.
+.IP "\fBmargins observed\fR"
+Lines can either be truncated at the right margin, or extend on forever.
+.IP "\fBauto paragraph formatting\fR"
+While typing in text, the editor can try to keep it looking reasonably well
+within the width of the screen.
+.IP "\fBeightbit characters\fR"
+Toggles whether eight bit characters are displayed as their value in angle
+brackets (e.g. "<220>") or as a character.
+.IP "\fBinfo window\fR"
+A window showing the keyboard operations that can be performed can be
+displayed or not.
+.IP"\fBemacs keys\fR"
+Control keys may be given bindings similar to emacs, or not.
+.RE
+.PP
+You may set these modes via the initialization file (see below), or with a
+menu (see above).
+.\"
+.\" spell checking
+.\"
+.SS "Spell Checking"
+.PP
+There are two ways to have the spelling in the text checked from \fIee\fR.
+One is by the traditional \fIspell\fR(1) command, the other is with the
+optional \fIispell\fR(1) command.
+.PP
+Using \fIspell\fR, the words that are not recognized will be placed at the top
+of the file. For the \fIispell\fR option, the file is written to disk,
+then \fIispell\fR run on the file, and the file read back in once
+\fIispell\fR has completed making changes to the file.
+.\"
+.\" printing
+.\"
+.SS "Printing the contents of the editor"
+.PP
+The user may select a menu item which prints the contents of the editor.
+.I ee
+pipes the text in the editor to the command specified by the
+initialization command
+.B printcommand
+(see the section
+.B Initializing ee from a file
+below). The default is to send the contents to "lp".
+.PP
+Whatever the user assigns to
+.B printcommand
+must take input from
+standard input. See your system administrator for more details.
+.\"
+.\" shell operations
+.\"
+.SS "Shell operations"
+.PP
+Shell commands can be executed from within
+.I ee
+by selecting the
+.B shell command
+item in the
+.B miscellaneous
+menu, or by placing an exclamation mark ("!") before the command to
+execute at the
+.B command:
+prompt. Additionally, the user may direct the contents of the edit buffer
+out to a shell operation (via a pipe) by using the left angle bracket
+(">"), followed by a "!" and the shell command to execute. The output of
+a shell operation can also be directed into the edit buffer by using a
+right angle bracket ("<") before the exclamation mark. These can even be
+used together to send output to a shell operation and read back the
+results into the editor. So, if the editor contained a list of words
+to be sorted, they could be sorted by typing the following at the command
+prompt:
+.RS 4
+.sp
+><!sort
+.sp
+.RE
+This would send the contents of the editor to be piped into the
+.I sort
+utility and the result would be placed into the edit buffer at the current
+cursor location. The old information would have to be deleted by the user.
+.\"
+.\" initializing ee from a file
+.\"
+.SS "Initializing ee from a file"
+.PP
+Since different users have different preferences, \fIee\fR allows some
+slight configurability. There are three possible locations for an
+initialization file for ee: the file \fI/usr/share/misc/init.ee\fR, the
+file \fI.init.ee\fR in the user's home directory, or the file \fI.init.ee\fR
+in the current directory (if different from the home
+directory). This allows system administrators to set some preferences for
+the users on a system-wide basis (for example, the \fBprint\fR command),
+and the user to customize settings for particular directories (like one
+for correspondence, and a different directory for programming).
+.PP
+The file \fI\/usr/share/misc/init.ee\fR is read first, then
+\fI$HOME/.init.ee\fR, then \fI.init.ee\fR, with the settings specified by the
+most recent file read taking precedence.
+.PP
+The following items may be entered in the initialization file:
+.RS 4
+.IP \fBcase\fR
+Sets searches to be case sensitive.
+.IP \fBnocase\fR
+Sets searches to be insensitive to case (default).
+.IP \fBexpand\fR
+Causes \fIee\fR to expand tabs to spaces (default).
+.IP \fBnoexpand\fR
+Causes \fIee\fR to insert tabs as a single character.
+.IP \fBinfo\fR
+A small information window is displayed at the top of the terminal
+(default).
+.IP \fBnoinfo\fR
+Turns off the display of the information window.
+.IP \fBmargins\fR
+Causes \fIee\fR to truncate lines at the right margin when the
+cursor passes beyond the right margin as set by the user
+while text is being inserted
+(default).
+.IP \fBnomargins\fR
+Allows lines to extend beyond the right margin.
+.IP \fBautoformat\fR
+Causes \fIee\fR to automatically try to format the current paragraph while
+text insertion is occurring.
+.IP \fBnoautoformat\fR
+Turns off automatic paragraph formatting (default).
+.IP \fBprintcommand\fR
+Allows the setting of the print command (default: "lp").
+.IP \fBrightmargin\fR
+The user can select a value for the right margin (the first column on the
+screen is zero).
+.IP \fBhighlight\fR
+Turns on highlighting border of information window and menus (default).
+.IP \fBnohighlight\fR
+Turns off highlighting of border of information window and menus.
+.IP \fBeightbit\fR
+Turns on display of eight bit characters.
+.IP \fBnoeightbit\fR
+Turns off display of eight bit characters (they are displayed as their decimal
+value inside angle brackets, e.g., "<220>").
+.IP \fBemacs\fR
+Turns on emacs key bindings.
+.IP \fBnoemacs\fR
+Turns off emacs key bindings.
