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.

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. - -The file new_curse.c contains a subset of 'curses', a package for -applications to use 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. Unless problems occur during the building -of ee, it is recommended that you use new_curse rather than the curses -supplied with your system. - -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". A make file which takes into account -the characteristics of your system will be created, and then ee will be -built. If there are problems encountered, you will be notified about -them. - -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. - -Hugh Mahon |___| -h_mahon@fc.hp.com | | - |\ /| - | \/ | - diff --git a/usr.bin/ee/ee.1 b/usr.bin/ee/ee.1 deleted file mode 100644 index 4da47bc52812..000000000000 --- a/usr.bin/ee/ee.1 +++ /dev/null @@ -1,623 +0,0 @@ -.\" -.\" $FreeBSD$ -.\" -.Dd August 30, 1995 -.Dt EE 1 -.Os -.Sh NAME -.Nm ee -.Nd easy editor -.Sh SYNOPSIS -.Nm -.Op Fl eih -.Op +# -.Op Ar -.Nm ree -.Op Fl eih -.Op +# -.Op Ar -.Sh DESCRIPTION -The -.Nm -utility -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 -.Nm ree -utility is the same as -.Nm , -but restricted to editing the named -file (no file operations, or shell escapes are allowed). -.Pp -For -.Nm -to work properly, the environment variable -.Ev TERM -must be set to indicate the type of terminal being used. -For -example, for an -.Tn HP 700/92 -terminal, the -.Ev TERM -variable should be set to "70092". -See your System Administrator if -you need more information. -.Pp -The following options are available: -.Bl -tag -width indent -.It Fl e -Turn off expansion of tab character to spaces. -.It Fl i -Turn off display of information window at top of terminal. -.It Fl h -Turn off highlighting of borders of windows and menus (improves -performance on some terminals). -.It Sy +# -Move the cursor to line '#' at startup. -.El -.Ss "Control keys" -To do anything other than insert text, the user must use the control -keys (the -.Li Control -key, represented by a "^", pressed in conjunction with an -alphabetic key, e.g., ^a) and function keys available on the keyboard -(such as -.Em "Next Page" , -.Em "Prev Page" , -arrow keys, etc.). -.Pp -Since not all terminals have function keys, -.Nm -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 -.Em ^u . -.Bl -tag -width indent -.It ^a -Prompt for the decimal value of a character to insert. -.It ^b -Move to the bottom of the text. -.It ^c -Get the prompt for a command. -.It ^d -Move the cursor down. -.It ^e -Prompt for the string to search for. -.It ^f -Undelete the last deleted character. -.It ^g -Move to the beginning of the line. -.It ^h -Backspace. -.It ^i -Tab. -.It ^j -Insert a newline. -.It ^k -Delete the character the cursor is sitting on. -.It ^l -Move the cursor left. -.It ^m -Insert a newline. -.It ^n -Move to the next page. -.It ^o -Move to the end of the line. -.It ^p -Move to the previous page. -.It ^r -Move the cursor to the right. -.It ^t -Move to the top of the text. -.It ^u -Move the cursor up. -.It ^v -Undelete the last deleted word. -.It ^w -Delete the word beginning at the cursor position. -.It ^x -Search. -.It ^y -Delete from the cursor position to the end of line. -.It ^z -Undelete the last deleted line. -.It ^[ (ESC) -Pop up menu. -.El -.Ss "EMACS keys mode" -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 -.Em settings -menu, or via the initialization file (see below). -The mappings are as follows: -.Bl -tag -width indent -.It ^a -Move to the beginning of the line. -.It ^b -Back 1 character. -.It ^c -Command prompt. -.It ^d -Delete character the cursor is sitting on. -.It ^e -End of line. -.It ^f -Forward 1 character. -.It ^g -Go back 1 page. -.It ^h -Backspace. -.It ^i -Tab. -.It ^j -Undelete last deleted character. -.It ^k -Delete line. -.It ^l -Undelete last deleted line. -.It ^m -Insert a newline. -.It ^n -Move to the next line. -.It ^o -Prompt for the decimal value of a character to insert. -.It ^p -Previous line. -.It ^r -Restore last deleted word. -.It ^t -Move to the top of the text. -.It ^u -Move to the bottom of the text. -.It ^v -Move to the next page. -.It ^w -Delete the word beginning at the cursor position. -.It ^y -Prompt for the string to search for. -.It ^z -Next word. -.It ^[ (ESC) -Pop up menu. -.El -.Ss "Function Keys" -.Bl -tag -width indent -.It Next Page -Move to the next page. -.It Prev Page -Move to the previous page. -.It Delete Char -Delete the character the cursor is on. -.It Delete Line -Delete from the cursor to the end of line. -.It Insert line -Insert a newline at the cursor position. -.It Arrow keys -Move the cursor in the direction indicated. -.El -.Ss Commands -Some operations require more information than a single keystroke can -provide. -For the most basic operations, there is a menu that can be -obtained by pressing the -.Tn ESC -key. -The same operations, and more can be performed by obtaining the -command prompt (^c) and typing in one of the commands below. -.Bl -tag -width indent -.It !

-.Em ^d -for moving down to move to the desired items in the menu, then press -.Em return -to perform the indicated task. -.Pp -To the left of each menu item is a letter, which if the corresponding -letter is pressed on the keyboard selects that menu entry. -.Pp -The main menu in -.Nm -is as follows: -.Bl -tag -width indent -.It leave editor -If changes have been made, the user will get a menu prompting whether or -not the changes should be saved. -.It help -Display a help screen, with all of the keyboard operations and commands. -.It file operations -Pop up a menu for selecting whether to read a file, write to a file, or -save the current contents of the editor, as well as send the contents of -the editor to a print command (see the section -.Sx "Initializing ee from a file" ) . -.It redraw screen -Provide a means to repaint the screen if the screen has been corrupted. -.It settings -Show the current values of the operating modes, and right margin. -By -pressing return when the cursor is on a particular item, the value can be -changed. -To leave this menu, press the -.Em escape -key. -(See -.Sx Modes -below.) -.It search -Pop up a menu in which the user may choose to enter a string to search -for, or search for a string already entered. -.It miscellaneous -Pop up a menu that allows the user to format the current paragraph, -execute a shell command, or check the spelling of the text in the editor. -.El -.Ss "Paragraph Formatting" -Paragraphs are defined for -.Nm -by a block of text bounded by: -.Bl -bullet -width indent -.It -Begin or end of file. -.It -Line with no characters, or only spaces and/or tabs. -.It -Line starting with a period ('.') or right angle bracket ('>'). -.El -.Pp -A paragraph may be formatted two ways: explicitly by choosing the -.Em format paragraph -menu item, or by setting -.Nm -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 -.Nm : -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 -.Em settings -menu, the default is for the margin to be the right edge of the -terminal). -This is the mode that allows the -.Em format paragraph -menu item to work. -.Pp -"Automatic formatting" provides word-processor-like behavior. -The user -may type in text, while -.Nm -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. -.Ss Modes -Although -.Nm -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: -.Bl -tag -width indent -.It tab expansion -Tabs may be inserted as a single tab character, or replaced with spaces. -.It case sensitivity -The search operation can be sensitive to whether characters are upper- or -lower-case, or ignore case completely. -.It margins observed -Lines can either be truncated at the right margin, or extend on forever. -.It auto paragraph formatting -While typing in text, the editor can try to keep it looking reasonably well -within the width of the screen. -.It eightbit characters -Toggle whether eight bit characters are displayed as their value in angle -brackets (e.g.\& "<220>") or as a character. -.It info window -A window showing the keyboard operations that can be performed can be -displayed or not. -.It emacs keys -Control keys may be given bindings similar to emacs, or not. -.It 16 bit characters -Toggles whether sixteen bit characters are handled as one 16-bit quantities or -two 8-bit quantities. -This works primarily with the Chinese Big 5 code set. -.El -.Pp -You may set these modes via the initialization file (see below), or with a -menu (see above). -.Ss "Spell Checking" -There are two ways to have the spelling in the text checked from -.Nm . -One is by the traditional -.Xr spell 1 -command, the other is with the -optional -.Nm ispell -command. -.Pp -Using -.Nm spell , -the words that are not recognized will be placed at the top -of the file. -For the -.Nm ispell -option, the file is written to disk, -then -.Nm ispell -run on the file, and the file read back in once -.Nm ispell -has completed making changes to the file. -.Ss "Printing the contents of the editor" -The user may select a menu item which prints the contents of the editor. -The -.Nm -utility pipes the text in the editor to the command specified by the -initialization command -.Em printcommand -(see the section -.Sx Initializing ee from a file -below). -The default is to send the contents to -.Xr lp 1 . -.Pp -Whatever the user assigns to -.Em printcommand -must take input from -standard input. -See your system administrator for more details. -.Ss "Shell operations" -Shell commands can be executed from within -.Nm -by selecting the -.Em shell command -item in the -.Em miscellaneous -menu, or by placing an exclamation mark ("!") before the command to -execute at the -.Em 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: -.Dl ><!sort -This would send the contents of the editor to be piped into the -.Xr sort 1 -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. -.Ss "Initializing ee from a file" -Since different users have different preferences, -.Nm -allows some -slight configurability. -There are three possible locations for an -initialization file for -.Nm : -the file -.Pa /usr/share/misc/init.ee , -the file -.Pa .init.ee -in the user's home directory, or the file -.Pa .init.ee -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 -.Em print -command), -and the user to customize settings for particular directories (like one -for correspondence, and a different directory for programming). -.Pp -The file -.Pa /usr/share/misc/init.ee -is read first, then -.Pa $HOME/.init.ee , -then -.Pa .init.ee , -with the settings specified by the -most recent file read taking precedence. -.Pp -The following items may be entered in the initialization file: -.Bl -tag -width indent -.It case -Set searches to be case sensitive. -.It nocase -Set searches to be insensitive to case (default). -.It expand -Cause -.Nm -to expand tabs to spaces (default). -.It noexpand -Cause -.Nm -to insert tabs as a single character. -.It info -A small information window is displayed at the top of the terminal -(default). -.It noinfo -Turn off the display of the information window. -.It margins -Cause -.Nm -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). -.It nomargins -Allow lines to extend beyond the right margin. -.It autoformat -Cause -.Nm -to automatically try to format the current paragraph while -text insertion is occurring. -.It noautoformat -Turn off automatic paragraph formatting (default). -.It printcommand -Allow the setting of the print command (default: "lp"). -.It rightmargin -The user can select a value for the right margin (the first column on the -screen is

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.
