aee.1

aee是一种易使用的文本编辑器。你可以不用说明书来使用它。它提供终端接口和本地的X-windows接口。它的特性包括即弹的菜单

inserting.
.IP "\fBnoover\fRstrike*\(dd" 22
Causes characters to be inserted into line at current cursor position without
replacing existing characters (default).
.IP \fBprint\fR 22
Sends the contents of the current buffer to the printer.  The command that is 
used can be specified in the \fIinit.ae\fR file, see section \fBInitializing 
aee From A File\fR.
.IP "\fBprintcommand\fR \(dg"
Allows the setting of the print command (default: "lp").
.IP \fBpwd\fR 22
Display the current directory.
.IP "\fBquit\fR[!]\(dd" 22
Quit the current edit session without writing a file.  The optional exclamation
mark has the same meaning as for the \fBexit\fR command.
.IP "\fBread\fR \fIfile\fR" 22
Read a file into the current buffer after 
the cursor.
.IP \fBreseq\fRuence 22
Renumber the lines.
.IP \fBsave\fR 22
Save the contents of the main buffer to the file being edited.
.IP "\fBsho\fRw [gold] \fIkey\fR" 22
Displays the function(s) assigned to the specified key.
.IP "\fBstatus\fR*\(dd" 22
A status line is displayed on the bottom line of the screen.
.IP \fBnostat\fRus*\(dd" 22
Turns off the status line (default).
.IP "\fBstops\fR \fInumber\fR *" 22
Tabs will be spaced every \fInumber\fR spaces, unless other tabs are set 
using the \fBtabs\fR command.
.IP "\fBtabs\fR [\fIstops ...\fR] *" 22
Sets tabs to \fIstops\fR.  After the last user defined tab stop, tabs 
are the normal sequence of every eight columns, or as set using 
the \fBstops\fR command.  The first column is 0.
.IP "\fBunta\fRbs \fIstops ...\fR *" 22
Removes the specified tab stops.
.IP \fBte\fRxt* 22
Turns text mode (default) .  Files read in while in text mode are checked 
whether they are UNIX files or Windows files.  If carriage return 
characters are found immediately prededing a new-line character, the 
editor treats the file as a DOS file and discards the carriage-returns 
on read, and carriage-returns are inserted on file write.  The menu may 
be used to toggle between DOS file mode and UNIX file mode.  See also 
\fBbinary\fR.
.IP "\fBwind\fRows*\(dd" 22
This command specifies whether or not buffers 
are displayed on the screen simultaneously.  If \fBwindows\fR (default) is 
specified, then buffers exist on the screen together.
.IP "\fBnowind\fRows*\(dd" 22
This command specifies that there is only one buffer on the 
screen at a time.
.IP "\fBwrite\fR \fIfile\fR" 22
Write the current buffer out to the specified file.
.IP 0123456789 22
Enter a number to go to the line corresponding to that number.
.IP "\fB+\fR or \fB-\fR \fInumber\fR \(dd" 22
Moves forward or back the number of lines specified.
.IP "[<\fIinbuff\fR] [>\fIoutbuff\fR ] \fB!\fRcommand" 22
Execute the command following the exclamation mark in the UNIX shell.  The 
shell used is the one specified in the shell variable \fBSHELL\fR in 
the user's environment, or \fB/bin/sh\fR if \fBSHELL\fR is not defined.  You 
may send data from the buffer \fIoutbuff\fR (or the current buffer if 
\fIoutbuff\fR is not specified) out to the shell by using the right angle 
bracket (>).  You may read into \fIinbuff\fR (or the current buffer if 
\fIinbuff\fR is not specified) by using the left angle bracket (<) as shown.  
The data read in from the
command will be placed after the current cursor location in the buffer

.SS Search and Replace
.PP
\fIaee\fR's search facility provides several abilities.  The user may 
choose for the search to be case sensitive, or ignore the case (upper or 
lower) of a character (\fBnocase\fR is the default).  The user may also 
choose \fBliteral\fR, or \fBnoliteral\fR (the default) modes for the 
search facility.  The \fBliteral\fR mode interprets the search string 
literally, \fBnoliteral\fR means that some characters (called 
\fRmetacharacters\fR) have special meaning, as described below:
.sp
.KS
.TS
center;
l l.
symbol	meaning

^	beginning of line
$	end of line
\\\\x	interpret 'x' literally
[abc]	T{
match a single character in the text 
to one in brackets
T}
[a-z]	T{
match a single character in the text 
to one in range a-z
T}
[^abc]	T{
match a single character in the text 
that is not within the brackets 
after '^' ('^' means 'not')
T}
*	T{
match any sequence of characters, 
useful in middle of string with 
known beginning and end, but 
variable middle
T}
\.	match any single character
.TE
.KE
.sp
.PP
The carat (^) within the square brackets ([]) means that the search will match
any characters \fInot\fR within the brackets.  The carat \fImust\fR be the 
first character after the opening bracket.
.PP
The asterisk (*) may be useful when searching for a string to which you know
the beginning and end, but not what characters (if any) or how many may be
in the middle.  The first character after the asterisk should not be a
metacharacter (a character with special meaning).
.PP
The replace facility uses the same modes as the search facility.  The 
prompt for the replace operation shows the syntax for the input:
.sp 2
.RS 4
/string1/string2/
.RE
.sp 2
where the slash ('/') may be replaced by any character that is not in the 
search or replacement string, and "string1" is to be replaced by 
"string2".  When in \fBnoliteral\fR mode, the search string may be placed 
in the replacement string by using the ampersand ('&'), like so:
.sp 2
.RS 4
/old/abc&123/
.RE
.sp 2
Where "old" will be inserted between "abc" and "123".

.SS Recovery
.PP
If for some reason an edit session is interrupted, it is possible to 
recover the work done in the session.  This is accomplished via the 
information stored in the journal file, which is a record of the 
changes made to the text in the buffer 
while in the editor.  To recover a session in which a 
file named \fIfoo\fR was being edited, use the command:
.sp
.nf
.na
.RS
aee -r \fIfoo\fR
.RE
.ad b
.fi
.PP
This is only possible if the \fB-j\fR option was not used, since the 
\fB-j\fR option turns journaling off.
.PP
It is also possible to start \fIaee\fR with no arguments, and then to browse 
the journal files.  This is accomplished through the menus.  To perform this 
task, bring up the menu by pressing the \fBEsc\fR key, select \fIfile 
operations\fR, then select \fIrecover from journal\fR.  You should then be 
presented with a list of files to recover.

.SS Key Definitions
.PP 
The function keys and control sequences (alphabetic keys pressed with 
the control key) may be defined by the user to perform any of the functions
described below.  
.PP
The user may assign more than one function to each key, as 
long as each one is separated by one or more spaces.  The following describes 
the functions of the keys and how the user may redefine the keyboard during 
the edit session on the command line.  The same syntax is used in 
the \fIinitialization file\fR.
.PP
Note that the '^' is typed by the user in the following examples, and 
is \fBnot\fR generated by pressing the control key and letter, and that f2 is 
entered by typing an 'f' and then a '2'.
.sp
Examples:
.br
.na
.nf
.sp
.RS
	\fBdefine ^b dl\fR
.RE
.ad b
.fi
.sp
will define the key control b to have the function delete line.
.sp
.na
.nf
.RS
	\fBdefine gold ^b udl\fR
.RE
.sp
.ad b
.fi
assigns the function undelete line to GOLD control b.
.sp
.nf
.na
.RS
	\fBdefine f2 /this is an inserted string/ cr\fR
.RE
.fi
.ad b
.sp
will cause the string between the delimiters (/) to be 
inserted followed by a carriage-return whenever the 
function key f2 is pressed.
.PP
If you wish to have a key that deletes to the end of line without appending
the next line to the end, you may make the following key definition:
.sp
.nf
.na
.RS
	\fBdefine f3 dl cr left\fR
.RE
.sp
.fi
.ad b
This set of functions will delete to the end of line and append the next to the
end of the line, then insert a line at the cursor, and then move the cursor 
back to the end of the previous line, the position where you started.  This may
of course be assigned to any valid key.

.SS Initializing aee From A File
.PP 
\fIaee\fR checks for a file named \fIinit.ae\fR in \fI/usr/local/lib\fR, 
.I .init.ae 
in the user's home directory, then for \fI.init.ae\fR in the 
current directory.  (This file may be created manually or by using the 
menu entry '\fIsave editor config\fR' in the 'settings' menu.)  
If the file exists, it is read 
and initializes \fIaee\fR to the parameters as defined in the file.  By having 
initialization files in multiple places, the user may specify settings for 
global use, and then supplement these with customization for the local 
directory.  The 
parameters allowed in the \fIinit.ae\fR file are key definitions, turning off 
windowing, case sensitivity, literal searching, eight bit characters, as 
well as the ability to echo strings to the terminal (see the \fBCommands\fR 
section for the commands allowed in the initialization file).  An example 
follows:
.nf
.na
.sp
.RS
