Mod.sources: Volume 8, Issue 7
Archive-name: se/Part07
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

o -- Option
The "o" (option) command allows any of several variables that
affect the editor's behavior to be set or tested. The
behavior of the "o" command depends upon what is typed after
the "o".
To find out about specific options, type "hoa", "hoc", "hod",
"hof", "hog", "hoh", "hoi", "hok", "hol", "holm", "hom", "hos",
"hot", "hou", "hov", "how", "hox", "hoy", "hoz", or "ho-".
To see how to set options with the command that invokes 'se',
type "hargs".
To return to the command directory, type "hcomdir".

o- -- Option - (dash)
default range syntax
1,$ o-[line number]
The "-" option controls the placement on the screen of a row
of dashes, which normally is off the screen above the top line
or hiding behind the bottom line of the help display. The
"window" through which you look at the edit buffer is the por-
tion of the screen BELOW the row of dashes but above the
command line (when it exists) or status line at the bottom.
"o-" alone puts the row of dashes above the top line; "o-"
followed by a SINGLE TERM line number puts it in place of the
line referred to on the screen, if possible.
For general information about the option command, type "ho".

oa -- Option Absolute
default range syntax
1,$ oa
"oa" toggles the Absolute line numbers flag, which determines
whether the numbers in the left margin shall be absolute line
numbers, or the (usually capital) letters that refer to lines
by the position at which they are being displayed on the
screen. In any case, the current line is always shown as "."
(with the "->" arrow to make it easy to find), the first line
in the buffer is labeled "1", and the last, "$" (when not
"."). Lines can be referred to by letter ONLY when the
letters appear in the left margin.
For general information about the option command, type "ho".
See also "hln" for how lines can be referred to in commands.

oc -- Option Case
default range syntax
1,$ oc
The "c" (case) option toggles the same case mapping flag that
is toggled by the CTRL-Z control character, but also changes
the marginal line letters to lower case (or back to upper), so
that typing a shifted letter will still refer to a line, and
typing an unshifted letter will do for a command letter. This
is useful for handling large amounts of upper case text, such
as Fortran programs.
For general information about the option command, type "ho".

else
cat << \SHAR_EOF > 'od'
od -- Option Delete
default range syntax
1,$ od[<|>]
The "d" option is for Delete direction. Typing "od<" fixes it
so that after you give a "d" command, the line BEFORE the
group of lines deleted becomes the current line (.). Typing
"od>" resets the normal behavior, in which the current line
pointer is always positioned AFTER the group of lines deleted
by the "d" command, if possible (Deleting the last line makes
the new last line the current line). Typing "od" alone
queries the delete direction flag, causing ">" or "<" to be
displayed.
For general information about the option command, type "ho".

of -- Option Fortran
default range syntax
1,$ of
Typing "of" turns on a package of options considered
convenient for editing Fortran. The warning column is set
to 72, and tab spacing is set to 7 +3 so that tabbing once
gets you to column 7. Tab expansion is also turned on
(XTABS). To undo "of" it is necessary to type "ot+3" and
"ox".
For general information about the option command, type "ho".

else
cat << \SHAR_EOF > 'og'
og -- Option Global
default range syntax
1,$ og
The "g" option controls the behavior of the Substitute command
when it is under the control of a Global command. Initially,
if a substitute inside a global command fails, se will not con-
tinue with the rest of the lines which might succeed. If "og"
is given, then the global substitute will continue, and lines
which failed will not be affected. Succesive "og" commands will
toggle this behavior. An explanatory message is placed in the
status line.

else
cat << \SHAR_EOF > 'oh'
oh -- Option Hardware Insert/Delete
default range syntax
1,$ oh
The "h" option controls the use of hardware line
insert/delete on terminals that have that capability. By
default, line insert/delete will be used if available. It
is occasionally useful to turn this option off when using
the editor on a terminal which can't keep up, or if the com-
munications lines may be scrambling the control characters.
Each successive "oh" merely toggles a switch within the
editor. An explanatory message is placed in the status
line.
For general information about the option command, type "ho".

then
echo shar: will not over-write existing file "'oi'"
else
cat << \SHAR_EOF > 'oi'
oi -- Option Indent
default range syntax
1, $ oi[a | <indent>]
"oi" selects the indent value for lines inserted with "a" and
"i" commands (initially 1). "a" selects auto-indent which sets
the indent to the value which equals the indent of the previ-
ous line. If neither "a" nor "<indent>" is specified, the
current value of indent is displayed.

ok -- Option OK
default range syntax
1,$ ok
Typing "ok" simply tests the flag that indicates whether the
edit buffer has been saved since the last change was made to
it. "Saved" or "Not saved" is accordingly displayed in the
remark field at the bottom of the screen.
To return to the option directory, type "ho".

else
cat << \SHAR_EOF > 'ol'
ol -- Option Line
default range syntax
1,$ ol[$ | . | # | BLANK]
The "l" option is the Line number monitoring option. Typing
"l" followed by "$" constantly displays the last line number
in the file (current length of the file). Typing "l" followed
by "." constantly displays the current line number. This
usually make sense only in conjunction with the "oa" option,
that uses letters for line names.
For general information about the option command, type "ho".

olm -- Option Line Margin
default range syntax
1,$ olm[<col>]
Sets the left margin to <col> which must be a positive integer.
This shifts the entire screen to the left; the characters that
were in columns 1 through <col> - 1 will not be visible. You
may continue editing in the normal fashion. To reset your screen
to normal, enter the command "olm 1". If <col> is omitted, the
current left margin column is displayed in the status line.

om -- Option Mail
default range syntax
1,$ om
"om" is an option which allows the user control over whether
or not he will be notified about pending mail. Typing "om"
simply toggles the switch controlling notification.
The default is for the editor to notify the user about his
mail. The mail box which the editor uses is taken from the
environment variable MAIL. If the mail box exists, but is empty
the user will not be notified.
To read your mail, use a shell escape on whichever of the fol-
lowing programs is appropriate:

ot -- Option Tab
range syntax
1,$ ot[[[+]integer [+]integer]]
"ot+3" sets the spacing between tab stops. The default value
when 'se' comes up is 3. Typing "ot" by itself causes the
current value of the parameter to be displayed. As an example
of how tabs are spaced out, if ot+6 is in effect, tab stops are
at 7, 13, 19, etc.
Variable tabs can be set by typing "ot 5 13 24 .. ". if you
do not prefer equally spaced ones.

ou -- Option Unprintable
default range syntax
1,$ ou[character]
The "u" option is for monitoring unprintable characters.
Typing "ou" by itself will return the current character used
to display unprintable characters. If it is ' ' (blank), then
unprintable characters are not checked and may mess up the
display. Typing "oux" where "x" is a printable character will
turn on character checking and display "x" everytime an
unprintable character is encountered. Unprintable characters
are not disturbed in the file, but can be "edited" out.
See also hccmisc for refreshing the display.

default range syntax
1,$ ov[integer]
The "v" option is the overlay column number. Typing "ov"
followed by a space and a number sets the column that the
cursor will be positioned at when issuing the "v" command.
Typing "ov $" will position the cursor at the end of the line.
Typing "ov" by itself will display the current value.

ow -- Option Warning
default range syntax
1,$ ow[integer]
The "w" option is the Warning column number. Typing "ow"
followed by a number sets the warning column threshold; simply
typing "ow" causes its current value to be displayed. When
you are about to type into a column of equal or greater number
than the warning column, the number of the column you are
about to type into is displayed on the bottom line along with
the string "col ".

default range syntax
. ox
"ox" turns compression of tabs on or off. If a file
has tabs in it, they will be expanded if compres-
sion is on. Otherwise they will be left alone, and
will show up as the default unprintable character.
The message "XTABS" will be displayed in the status
line if tab compression is on.

This option allows you to edit encrypted files. oy followed by a key
will cause e, r, and w, commands to encrypt and decrypt files using
crypt(1). oy will toggle the current encryption setting. If there
is no current key, se will ask you for one. If encryption is turned
on, it will be turned off. Encryption in indicated by the message

A PATTERN is a string of characters that specifies a set of
possible strings of characters that are said to MATCH the
pattern. Most characters in patterns stand for themselves,
but there are metacharacters: "." that matches any
character, "*" that along with the previous character, matches
any number of repetitions of it (including none), "^" for
beginning of line, "$" for end of line, and characters in
brackets "[]" to match any of the characters. The special
sense of metacharacters and of the delimiters in which the
pattern is enclosed can always be turned off by preceeding
them with the escape character "\".
See also "hs", "hg", "hx" for uses of patterns.
For the use of patterns in line numbers, type "hscan".
For examples of pattern matches, type "hpatex".

is used, all occurrences of the "change-this" pattern are
changed. If "change-this" is empty, the most recent pattern
from this command (e.g. within the range field) or a previous
command is used. If "to-this" is a '%', the previous replace-
ment pattern is used. The "/" may be any character. The trail-

For details about PATTERNs, type "hpat".
A line number term consisting of a PATTERN between slashes
causes a scan to begin with the line after the current line.
If the last line is encountered, the scan continues with line
1. The current line is the last to be examined. The line
referred to is the first line encountered in the scan that
contains a match for the pattern. If the entire buffer
contains no match, then an error is flagged. If the pattern
is enclosed in question marks, the scan is in the reverse
direction and begins with the line just before the current
line, and wraps around to the last line after line 1 is
examined. ">" and "<" mark name searches proceed in the same
wraparound fashion.

The "=" command displays the last line number in the line
number list (default ".") as a number. For example, "="
prints the line number of the current line, or "$=" prints the
line number of the last line (the number of lines).
The ":" command, with no preceeding line numbers, moves the
window so that the next screenful of text is visible. With a
line number, it makes the window begin at the referenced line.
The top line in the window becomes the current line.

Command Terminating Control Characters
The Carriage Return character terminates a command, but first
erases any characters at and to the right of the cursor.
CTRL-V, on the other hand, skips the cursor to the right end
of the line, then terminates it. The "Funny Return" character
CTRL-F serves different purposes depending on what routine is
soliciting the command.

after changes are made. E.g. if you substituted "pat" for
"hat" in a line, to reverse that operation immediately, simply
type "u" (RETURN).
2. "ud" is used to restore a group of lines that have been
delete E.g. if "n,md" deletes lines n thru m, then if you
position the curser to line n-1 and issue "ud" the deleted
lines will appear. (Or you can set the od toggle to od< so
that the line pointer is automatically set to n-1.

default range syntax
1,$ w[! | + | >] [file name]
"w" writes the buffer to a file. If issued without a file
name the current file name is used. If "f" was used to change
the file name or if a file name was given, a new file will be
created and written unless the file already exits which causes
a warning. The warning may be bypassed using "w!". Options
[+] or [>] mean to append to the file instead of writing over
it. Se expands environment variables occuring in file names.

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

z -- do special extended things
default range syntax
lines must be given line,line z <option> <stuff>
The z command command is used for doing special extended
things. Currently, the only option available is b, to draw
a box into the buffer. It works as follows:
lin,lin zb<left>[,<right>][<char>]
The two <lin>s specify where in the buffer to put the box,
<left> and <right> tell which column to which column, and
the <char> is the character to use to draw the box. As an
example,
.,.+4zb10,50*
draws a box, OVER the text that is there. Try it on some
BLANK lines.
