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. + +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/create.make b/usr.bin/ee/create.make new file mode 100755 index 0000000..9c41f89 --- /dev/null +++ b/usr.bin/ee/create.make @@ -0,0 +1,267 @@ +#!/bin/sh + +# +# This script will determine if the system is a System V or BSD based +# UNIX system and create a makefile for ee appropriate for the system. +# +# $Header: /home/hugh/sources/old_ae/RCS/create.make,v 1.6 1995/08/21 02:25:23 hugh Exp $ +# + +# test for existence of termcap (exists on both BSD and SysV systems) + +if [ -f /etc/termcap -o -f /usr/share/lib/termcap ] +then + termcap_exists="TRUE" +else + termcap_exists="" +fi + +# test for terminfo directory (exists on SysV systems) + +if [ -d /usr/lib/terminfo -o -d /usr/share/lib/terminfo ] +then + terminfo_exists="" +else + terminfo_exists="-DCAP" +fi + +# test for existence of termio header (on SysV systems) + +if [ -f /usr/include/termio.h ] +then + termio="-DSYS5" +else + termio="" +fi + +# test for sgtty header (on BSD systems) + +if [ -f /usr/include/sgtty.h ] +then + sgtty="TRUE" +else + sgtty="" +fi + +# look for select call in headers, make sure headers exist + +HEADER_FILES="" + +if [ -f /usr/include/sys/time.h ] +then + HEADER_FILES="/usr/include/sys/time.h " +fi + +if [ -f /usr/include/sys/types.h ] +then + HEADER_FILES="$HEADER_FILES /usr/include/sys/types.h" +fi + +if [ -n "$HEADER_FILES" ] +then + string="`grep select $HEADER_FILES`" + if [ -n "$string" ] + then + BSD_SELECT="-DBSD_SELECT" + else + BSD_SELECT="" + fi +fi + +# check for existence of select.h (on AIX) + +if [ -f /usr/include/sys/select.h ] +then + select_hdr="-DSLCT_HDR" +else + select_hdr="" +fi + +# check for stdlib.h + +if [ -f /usr/include/stdlib.h ] +then + HAS_STDLIB=-DHAS_STDLIB +else + HAS_STDLIB="" +fi + +# check for stdarg.h + +if [ -f /usr/include/stdarg.h ] +then + HAS_STDARG=-DHAS_STDARG +else + HAS_STDARG="" +fi + +# check for unistd.h + +if [ -f /usr/include/unistd.h ] +then + HAS_UNISTD=-DHAS_UNISTD +else + HAS_UNISTD="" +fi + +# check for ctype.h + +if [ -f /usr/include/ctype.h ] +then + HAS_CTYPE=-DHAS_CTYPE +else + HAS_CTYPE="" +fi + +# check for sys/ioctl.h + +if [ -f /usr/include/sys/ioctl.h ] +then + HAS_SYS_IOCTL=-DHAS_SYS_IOCTL +else + HAS_SYS_IOCTL="" +fi + +# check for sys/wait.h + +if [ -f /usr/include/sys/wait.h ] +then + HAS_SYS_WAIT=-DHAS_SYS_WAIT +else + HAS_SYS_WAIT="" +fi + +# check for localization headers + +if [ -f /usr/include/locale.h -a -f /usr/include/nl_types.h ] +then + catgets="" +else + catgets="-DNO_CATGETS" +fi + +# make decisions about use of new_curse.c (use of new_curse is recommended +# rather than local curses) + +if [ -n "$terminfo_exists" -a -z "$termcap_exists" ] +then + echo "Neither terminfo or termcap are on this system!

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. diff --git a/usr.bin/ee/ee.msg b/usr.bin/ee/ee.msg new file mode 100644 index 0000000..6c5ef75 --- /dev/null +++ b/usr.bin/ee/ee.msg @@ -0,0 +1,179 @@ +$ This file contains the messages for ee ("easy editor").
