<B>Digital的Unix操作系统VAX 4.2源码</B>

If this command is invoked on the outside or there are any leaks
to the outside, the entire outside will be filled in.
(Undo is useful in this case.)
Filling in cannot jump diagonals,
but can rather only spread in the four orthogonal directions.
.PP
.IR "g <x>" :
Get a glyph.
X can be any character.
The glyph corresponding to x is put in a window, and this
window is made the current window.
The glyph is centered horizontally in the window.
The baseline is located at row 70 from the top of the window.
The pen and cursor are placed at the base,
and the cursor is turned off.
The glyph must exist.
.PP
.IR h ,
.IR j ,
.IR k ,
and
.I l
are accepted to mean
left, down, up, and right, respectively.
They are synonymous with the alphanumeric arrow keys.
They have the same meanings as in
.IR vi(1) .
.PP
.IR "m" :
Move the mark to the current location of the cursor.
The cursor is turned on.
.PP
.IR "n <x>" :
New glyph.
This is similar to
.IR g ,
except that the glyph must
.I not
exist.
It is used to create a new glyph.
A blank window is created, centered at (50, 70) as in g.
.PP
.IR p :
Print the contents of the screen.
An HP 2631 printer must be connected to the terminal.
The screen is copied to the printer.
If in inverse video mode,
the screen is changed to normal video mode before the print,
and then changed back after the print.
.PP
.IR r :
If the rubber band line is on, turn it off.
Otherwise, turn it on.
.PP
.IR "s <what> [<where>]" :
Set <what> to <where>.
What and where are single characters.
The possibilities are:
.RS
.PP
.IR spf :
Set pen fine.
(`l' for light is also accepted.)
.PP
.IR spb :
set pen bold.
(`h' for heavy is also accepted.)
.PP
.IR sd :
Set draw.
The pen is used instead of the eraser.
.PP
.IR se :
Set erase.
The eraser is used instead of the pen.
.PP
.IR ss<n> :
Set size of bold pen.
<n> is a digit from 1 to 9.
The size of the bold pen is set accordingly.
This also affects the bold eraser.
.RE
.PP
.IR u :
Undo.  The previous change to the current window is undone.
Note that undo is on a window by window basis, so that
commands that affect characters or more than one window cannot be undone.
.PP
.IR "z <n>" :
Zoom to level n.
The screen is blown up by a factor of n.
This only affects the appearance of the screen
to make it easy to see the individual dots,
and does not affect the size of the glyph or
the result of a print command.
Zooming to 1 shows the entire screen, a level of 3 or 4
is probably good for editing glyphs.
When a message is printed on the screen, fed automatically
zooms out to level 1 so you can read the message.
Hitting space will zoom back.
z followed by <return> zooms out without changing the previous zoom.
.PP
.IR space :
Zoom back to the level most recently requested by the z command.
.PP
.IR "A <i/e/r> <first> <last> [<oldps> <newps>]" :
.br
Artificially italicize/embolden/resize a range of glyphs in the current font.
Enter i for italicize, e for embolden, or r for resize,
and the first and last character in the range desired.
If you are resizing you will also have to enter the old and new point
size, each terminated by a return.
Each glyph is gotten and changed on the screen visibly.
Glyphs are italicized by slanting them to the right at a slope of 1/5.
They are emboldened by smearing them to the right a number if pixels
equal to the current heavy pen size.
They are resized with an algorithm which translates all on bits
to the new position.
These operations will be considerably faster if the
.B \-q
option is in effect,
since much overhead is involved in the graphic display.
.PP
.IR B :
Move the base to the cursor.
The cursor is turned on.
.PP
.IR "C <from> <to>" :
Copy the glyph in character <from> to character <to>.
If <from> has a window on the screen, that window is
given to <to>.
.PP
.IR "D <from> <through>" :
Delete a range of characters in the font, from <from> through <through>
inclusive.  To delete a single character type it twice.
.PP
.IR "E <file>" :
Edit the named file.
If changes have been made to the current file,
confirmation will be requested.
(Either 'y' or 'E' is accepted.)
The file name is terminated with return.
.PP
.IR "F <first> <last>" :
Show the font on the screen.
The characters in the specified range are shown.
The width values are used to get natural spacing.
The display will remain until another command is typed,
at which time the previous display will be redrawn and
the new command will be executed.
As a special case, a ``p'' command will print the results
of the ``F'' command instead of the previous display.
.PP
.IR "I <h/v>" :
Invert the current glyph about a horizontal or vertical axis,
as indicated by
.I h
or
.IR v .
The axis runs up the center of the window.
The base can be subsequently positioned with the
.I B
command.
.PP
.IR K :
Kill the current glyph.
All dots are set to blank.
The glyph is not removed from the font.
This is used for redrawing a glyph from scratch or
replacing it with another glyph.
.PP
.IR "M <from> <to>" :
Move a glyph from <from> to <to>.
This is just like the copy command but the original is deleted.
.PP
.IR "N <file>" :
Write out the current file, if necessary, and edit the new file specified.
The file name is terminated with return.
.PP
.IR "P <first> <last> <file>" :
Partial read from a file.
A file and the first and last characters in the range are prompted for.
Characters not in the range are left unmodified,
characters in the range are handled as in the R command.
.PP
.IR Q :
Quit the editor, without saving any work.
If changes have been made confirmation will be required
(either `Q' or 'y' is taken as `yes'.)
.PP
.IR "R <file>" :
Read in the named file on top of the current file.
Glyphs are merged wherever possible.
If there is a conflict, you will be asked whether fed should
take the glyph from the file (f) or buffer (b).
Responding with F or B will lock in that mode for the remainder of the read.
The file name is terminated with a return.
.PP
.IR "T <text>" :
Typeset the line of text on the terminal.
This is similar to the F command except that
the given text is arranged on the screen, so
you can see how some particular combination of characters would look.
.PP
.IR V :
Toggle whether editing is being done in inverse video mode.
.PP
.IR "W <file>" :
Write the buffer out onto the named file,
which is terminated by return.
A null file name means the current file name.
.PP
.IR "ZZ" :
Exit fed.
A write is done, if necessary,
followed by a quit.
This is the normal way to leave fed.
The Z must be doubled for compatibility with
.IR vi .
.PP
.IR "." :
Turn on the dot under the cursor.
The cursor is turned off.
.PP
.IR ">" :
Turn off the dot under the cursor.
The cursor is turned off.
.PP
.IR "# <char> <field> <value>" :
Edit a numerical field.
This only makes sense if the glyph has not been gotten
.RI ( g
or
.IR n )
yet,
since otherwise the values are taken from window specific things
such as the base.
Fed does not do any sanity checking, but just substitutes the value input.
Fields are the first letter of any field from the dispatch structure
(see vfont(5)), specifically, these fields are
.IR addr ,
.IR nbytes ,
.IR left ,
.IR right ,
.IR up ,
.IR down ,
and
.IR width .
The number, which may be signed, is terminated by a newline.
