Subject:  v08i006:  Georgia Tech 'se' Screen Editor
Newsgroups: mod.sources
Approved: mirror!rs

Submitted by: emoryu1!arnold (Arnold D. Robbins)
Mod.sources: Volume 8, Issue 6
Archive-name: se/Part06


Here is the second release of the Georgia Tech Screen Editor, 'se'.
There were enough changes that a whole new posting is warranted.

Major Changes:
    All Georgia Tech specific stuff removed.
    It understands window size changes on 4.3BSD and ATT Unix PC/3B1
    Support for the shared library on the ATT Unix PC/3B1
    Considerable source code reorganization in certain files.

Enjoy,

Arnold Robbins

README:

This directory contains the help files for the Georgia Tech Software Tools/UNIX
screen editor Se.

The files should be installed in the directory /usr/local/lib/se_h for se in
order for se to find them. File names must be in lower case, since dohelp() maps
the file name into all lower case. (On pr1mes, case is not significant in
file names, so the original ratfor version did not have to do this.)

                          .           a

        "a" is for appending new lines of text after a given line.  If
        no line number is typed before the "a", text will be  appended
        after  the  current  line.  The last line appended becomes the
        current line.  To signal the end of  the  appended  text,  you
        type a "."  on a line by itself.  Control characters "f", "v",
        "l",  and  "k"  work differently for "a" command than for "v".
        "a:"  works as a one line append (i.e. anything following  the
        colon is appended after the current line).

        To return to the command directory, type "hcomdir."
        See also:  "hcc" (control characters) and "hc" (change).

                               Abort character

        CTRL-F ("Funny Return") character  is  used  to  abort  a  "v"
        command  before  all  the  specified lines have been modified.
        Typing it causes the current line to be restored to its  state
        of  before  the  "v" command was begun, and causes a return to
        the editor's command level.


        Type "hv" for a description of the "v" command.
        Type "hrpt" for CTRL-F's meaning if in append or command mode.
        Type "htermchar" for info about other termination characters.

                               Arguments (cont)

        Once the terminal type  is  established,  the  remaining  arg-
        uments  are  interpreted  thus:  if the argument begins with a
        "-", the rest of it is interpreted as though it appeared after
        the "o" in an option command.  For  example,  an  argument  of
        "-w10"  acts  as  a command "ow10".  On the other hand, if the
        argument does not begin with "-", it is interpreted as a  file
        name  (path-  name).   The  named  file  is read into the edit
        buffer, and its name becomes the  remembered  file  name.   If
        more  than one file is named, the edit buffer will contain the
        contents of all the files.  If  an  error is encountered while
        interpreting arguments (file not found, illegal  option),  the
        remainder will be ignored.

        For invoking command syntax, type "hargs".

                              Argument Handling

        The syntax for 'se's invoking command is usually given as
            se {-<option> | <pathname>}
        It is suggested  that  you  set up a command  file  that  will
        automatically invoke 'se' with the options that you like.

        To see how the remaining arguments are treated, type "harg2".
        To return to the general help directory, type "hdir".

          1,$                             !<m>command

        Similar to the "x" prefix, except that  "command" is performed
        for all lines in the range that do not have the mark name <m>.

        To return to the command directory, type "hcomdir".

            There is a limit (MAXLINE - 2) on the number of characters
        in a line. Se's MAXLINE is currently 512, so this isn't too much
        of a problem.
            If a filename is absent when invoked, all of the
        options are not processed.


        To go all the way back to the general help display, type "h".

        "c"  first  deletes  the range of lines determined by the line
        numbers (default ".,."), then enters append mode so  that  you
        can  type  lines to replace the deleted lines.  Append mode is
        terminated with a dot on a line by itself, as with the  Append
        command. "c:" works as a one line change (i.e. what  is  after
        the colon replaces the current line).

        To return to the command directory, type "hcomdir."
        See also   "ha" and "hd"

        Control characters can be used for correcting typing mistakes,
        for correcting commands that have incurred an error message,
        or for editing the edit buffer ("inline editing") via the "v"
        command.  The novice should be told right away that hitting
        the DEL or RUBOUT key is a way to erase an erroneous command.

         CTRL-Z toggles an indicator that acts as a "shift lock",
         controlling case mapping on alphabetics typed.

         CTRL-Q signals the editor that you suspect that for some
         reason the screen is garbaged.  The response is to clear and
         restore the screen.

        CTRL-A toggles Insert Mode.

        When Insert Mode is in effect, any printing character typed is
        inserted into the line, with characters at and to the right of
        the cursor moving over to make room.  When Insert Mode is  not
        in effect, any printing character typed will replace (overlay)
        the character at the cursor.

                                Command Syntax

        A command consists  of  an  optional  list  of  LINE  NUMBERS,
        followed  by a COMMAND LETTER, possibly followed by parameters
        allowed or required for a specific  command.   Preceeding  all
        this,  there  can be a GLOBAL PREFIX preceeded optionally by a
        list  of  line   numbers.   Hence   the   whole   syntax   is:

        [[<list>]<global prefix>][<list>]<command letter>[<stuff>]

        For general information about commands, type "hcom".
        For information about specific commands, type "hcomdir".
        For GLOBAL PREFIX syntax and semantics, type "hg".
        For LINE NUMBER LIST syntax and semantics, type "hlist".

        execution of the "d" command is controlled by the "d"  option;

        override a check made to prevent you from accidently losing  a
        buffer that has not been saved (same as in "q"). [x]   is used

        You are using 'se', the  Georgia  Tech screen editor which  is
        based upon the editor described in the book SOFTWARE TOOLS, by
        Brian W.  Kernighan  and  P.   J.   Plauger   (Addison-Wesley,
        1976).   The  screen-oriented  modifications (and some others)
        are by  Jack  Waugh and  Perry  Flinn.  Dan Forsyth translated
        the Ratfor into C.  Arnold Robbins modified the editor to  use
        the Berkeley termlib library, making the editor terminal inde-
        pendant.  Most of this  'help' is  courtesy  of Bob  Gordon of
        Prime  Research, as  amended by  Arnold Robbins.  The descrip-
        tion before you now  is  invoked by the  "h" (help) command.

        For a description of the 'help' command, type "hh".
        Find out what the help command can tell you - type "hdir".

        being edited.  f [file name] resets the name for the current
        file.  This filename is used by the "w", "e", and  "r"  com-
        mands  when  no  parameters are provided.  f does not change
        the "ok" toggle.  f with no parameters prints out the remem-

        "g"  is  used  to perform an editing command on all lines that
        match the "pattern".   "pattern"  is  any  legal  pattern  and
        command is an editor command.  The "x" command is the converse
        of "g" and performs the command on all lines that do not match
        the pattern.  The "/" may be any character.

        "i"  is  for  inserting new lines of text before a given line.
        If no line number is  typed  before  the  "i",  text  will  be
        inserted  before  the  current  line.   Lines  are continually
        inserted before the original line, which has the  same  effect
        as  append  does.  To signal the end of the inserted text, you
        only need to type  a  "."   on  a  line  by  itself.   Control
        characters  "f",  "v",  "l",  and "k" work differently for "i"
        command than for "v". "i:" works as a one line insert, similar
        to "a:".

        If "string" is present, it is inserted between each pair  of
        lines  joined.  If not, a single blank is used.  "j/" is the

                            List (of line numbers)

        A  line  number list consists of one or more LINE NUMBERs sep-
        arated with commas or semicolons.  The last two  line  numbers
        in  the  list  usually  specify  the  scope of a command.  For
        example, "5,7d" means delete lines 5 through 7.  If  the  list
        consists  of  only one line number, it is equivalant to a list
        with that line number written twice with a  comma  separating.
        The  sense of the semicolon is to set the CURRENT LINE POINTER
        to the value of the line number before  the  semicolon  before
        evaluating  the  line  number after it, whose value may depend
        upon the value of the current line pointer.

        A  LINE  NUMBER  refers  to  a line in the edit buffer.  The
        lines are always numbered sequentially starting with  1.   A
        line  number can be expressed as an integer, as "."  meaning
        the CURRENT LINE, "^" or "-" meaning  the  line  before  the
        current  line,  "$"  meaning  the  last  line,  as a PATTERN
        enclosed in "/" slashes for a forward  scan,  as  a  pattern
        enclosed  in  "?"   question marks for a backward scan, as a
        MARK NAME preceeded by "<" for a backward search or  by  ">"
        for  a forward search, or as any additive combination of the
        above by joining them with operators "+",  "-",  or  nothing
        (meaning "+").

        Type "hlist" for line number list syntax.
