A number of people often post questions asking for editors which have
certian features.  

I have been working on a summary of features available in a few 
editors.  The summary is organized in a tabular check-sheet format
listing features available for various text editors with a general indication
of how well the feature/command is supported with respect to other
editors.

Perhaps this table (when further filled in) might be useful 
addition to the  comp.text.editors  FAQ.

I would like to hear comments, and suggestions for additional features,
and table entries for additional editors.
Fill out a table column for your favorite editor and send it to me,
and I will add it to the compendium and submit it to Ruben Olson for
possible inclusion in the archive.

The table is listed first followed by footnotes, followed by a detailed 
description of the features listed in the first column.

                         TEXT EDITOR COMPENDIUM

The following is a tabular cross reference of text editors that are available
on a variety of computers/operating systems.

Codes:

     y     The editor supports this feature
     n     The editor doesn't support this feature at all
     +     The editor supports this better than most editors
     -     The editor supports this but not very well other editors do better
     ~     The editor does this another way but not necessarily better
     !     The editor does this another way better
     M     The editor comes with a macro to do this
     m     A macro could be written to do this
     O     Optional (the feature may be enabled/disabled somehow)
     ?     Don't know
     y?/n? Don't know for sure
     NA    Not applicable or unnecessary with the editing model
   number  see footnote
   #number The editor supports this number of X's (Ie number of buffers)
     #!    The editor supports an unlimited number of X's

For example:  Support of regular expressions,

    Vi has very good support of regular expressions so it would get a 'y+'
    The borland compiler text editors offer regular expression searching,
    but only a subset of options, this would qualify for  a 'y'.
    An editor offering wild cards (Ie * or ?) would qualify for 'n-' or
    may be a '~'.
    An editor which has a search string construction interface that makes
    regular expression like searches easier would get a '!'.

   Y    The version supports almost all basic functions
   y    The version supports most basic functions and may have some extensions
        or there is another editor (clone) which supporst most basic function.
   y-   The version supports most basic functions and has some restrictions
   n+   There is no specific version, but there exists another editor 
        with very similar features that supports many basic functions.
   n    There is no similar editor available.
   ?    It is possible that the could compile and run on this machine with

The term 'buffers' (as in multiple buffers) refers to the editors' ability to
maintain multiple file editing sessions simultaneously

1  REDT can tally columns of numbers. Count, sum, average registers can be
   inserted in the text.
2  To qualify for cut/paste regions, the editor must be able to start/stop
   at a column within a line.  Vi and Xedit multiple line delete/copy doesn't
   qualify.
3  REDT uses columwise like region selection to define the sort key.
   Previous line orientation is preserved so that multiple key sorts 
   are possible.
4  REDT window resizing is supported in the Amiga and X windows version.

(10) EDT,SEDT,and REDT offer interactive search and replace, but not
   regular expressions.  Vi offers regular expressions but not interactive
   search and replace.  Borlands editors do this very well

(11) Does the editor offer window resizing greater than 80x25 if the 
    terminal (Ie Xwindow) supports it?  Can windows be made smaller than
    80x25? 

    SEDT and EVE/TPU will half window sizes for split screen and will
    extend window columns for 132 column mode terminals.  

    EDT supports 132 column terminals.  

    Vi may or may not size to the terminal's screen size depending on the 
    implementation.  

    Stevie (amiga and Atari?ST versions can be dynamically resized).

    EMACS resizes windows for split screens and will size windows for 
    Xwindows. 

    REDT will automatically size to the terminal screen size at startup
    but cannot be resized.  The Amiga and Xwindow versions can be resized 
    dynamically.

      adjust - The user may adjust this limit before or during the editing
               session.
      
      nolim  - Limited only by available memory or other hardware limitations
               or a generally large arbitrary number.
      
      To qualify as having multiple buffers, the user should be able to (at
      least) easily move between buffers, and cut/paste (yank/put) text.
