NAME

       ledit - line editor, version 2.04

SYNOPSIS

       ledit [-h file] [-x] [-t] [-l length] [-a | -u] [command options]

DESCRIPTION

       The command ledit allows one to edit lines one by one when running an interactive command.
       When typing a line, some keys with control or meta are  interpreted:  it  is  possible  to
       insert  characters  in the middle of the line, go to the beginning or the end of the line,
       get a previous line, search for a line with a pattern, etc.

OPTIONS

       The options are:

       -h file
              Save the lines typed (history) in file. The default is to have them only in  memory
              (so, they are lost at the end of the program).

       -x     Extend the history file (given in option "-h") if it already exists. The default is
              to truncate the history file.

       -t     Display the sequences generated by the keys (for debugging).

       -v     Print ledit version and exit.

       -l length
              Tells that length is the maximum line length  displayed.  If  the  line  edited  is
              longer  than this length, the line scrolls horizontally, while editing. The default
              value is 70.

       -a     Ascii encoding: characters whose code is greater than  128  are  displayed  with  a
              backslash followed by their code.

       -u     Unicode  encoding:  the  terminal  must have been set in unicode mode. See commands
              unicode_start and unicode_stop.

       command options
              Runs the command command and its possible options. This must be the last option  of
              ledit. The default value is "cat".

KEYS BINDINGS

       When  ledit  starts,  some  default  key bindings are defined. The can be completed with a
       "leditrc" file. See the section LEDITRC.

       In the following lines, the caret sign "^" means "control" and  the  sequence  "M-"  means
       "meta" (either with the "meta" prefix, or by pressing the "escape" key before). Examples:

       ^a        press  the  "control"  key,  then  press  "a",  then  release  "a", then release
                 "control".

       M-a       press the "meta" key, then press "a", then release "a", then release "meta", or:
                 press and release the "escape" key, then press and release "a" (the manipulation
                 with "meta" may not work in some systems: in this  case,  use  the  manipulation
                 with "escape").

       The default editing commands are:

             ^a   : beginning of line
             ^e   : end of line
             ^f   : forward char
             ^b   : backward char
             M-f  : forward word
             M-b  : backward word
             TAB  : complete file name
             ^p   : previous line in history
             ^n   : next line in history
             M-<  : first line in history
             M->  : last line in history
             ^r   : reverse search in history (see below)
             ^d   : delete char (or EOF if the line is empty)
             ^h   : (or backspace) backward delete char
             ^t   : transpose chars
             M-c  : capitalize word
             M-u  : upcase word
             M-l  : downcase word
             M-d  : kill word
             M-^h : (or M-del or M-backspace) backward kill word
             ^q   : insert next char
             M-/  : expand abbreviation
             ^k   : cut until end of line
             ^y   : paste
             ^u   : line discard
             ^l   : redraw current line
             ^g   : abort prefix
             ^c   : interrupt
             ^z   : suspend
             ^\   : quit
             return : send line
             ^x     : send line and show next history line
             other  : insert char

       The arrow keys can be used, providing your keyword returns standard key sequences:

             up arrow    : previous line in history
             down arrow  : next line in history
             right arrow : forward char
             left arrow  : backward char

       Other keys:

             home        : beginning of line
             end         : end of line
             delete      : delete char
             page up     : previous line in history
             page down   : next line in history
             shift home  : beginning of history
             shift end   : end of history

REVERSE SEARCH

       The  reverse  search  in  incremental,  i.e. ledit backward searches in the history a line
       holding the characters typed. If you type "a",  its  search  the  first  line  before  the
       current  line  holding  an  "a" and displays it. If you then type a "b", its search a line
       holding "ab", and so on. If you type ^h (or backspace), it returns to  the  previous  line
       found. To cancel the search, type ^g. To find another line before holding the same string,
       type ^r.  To stop the editing and display the current line  found,  type  "escape"  (other
       commands of the normal editing, different from ^h, ^g, and ^r stop the editing too).

       Summary of reverse search commands:

             ^g  : abort search
             ^r  : search previous same pattern
             ^h  : (or backspace) search without the last char
             del : search without the last char
             any other command : stop search and show the line found

LEDITRC

       If  the  environment  variable  LEDITRC  is set, it contains the name of the leditrc file.
       Otherwise it is the file named ".leditrc" in user's home directory. When  starting,  ledit
       reads this file, if it exists, to modify or complete the default bindings. If this file is
       changed while reading lines, it is read again to take the new file into account.

       Bindings lines are the ones which start with a string defining the key sequence and follow
       with a colon and a binding. A binding is either a string or a command. The other lines are
       ignored For example,the line:

           "\C-a": beginning-of-line

       binds the sequence "control-a" to the command "beginning-of-line".

       The key sequence may contain the specific meta-sequences:

           \C-   followed by a key: "control" of this key
           \M-   followed by a key: "meta" of this key
           \e    the "escape" key
           \nnn  where nnn is one, two, or three octal digits, or:
           \xnn  where nn is one or two hexadecimal digits:
                   the binary representation of a byte
           \a    bell = \C-g
           \b    backspace = \C-h
           \d    delete = \277
           \f    form feed = \C-l
           \n    newline = \C-j
           \r    carriage return = \C-m
           \t    tabulation = \C-i
           \v    vertical tabulation = \C-k

       The commands are:

         abort: do nothing
         accept-line: send the current line
         backward-char: move the cursor to the previous character
         backward-delete-char: delete the previous character

         capitalize-word: uppercase the first char and lowercase the rest
         delete-char: delete the character under the cursor
         delete-char-or-end-of-file: same but eof if no character in the line
         downcase-word: lowercase whole word
         end-of-history: display the last line of the history
         end-of-line: move the cursor to the end of the line
         expand-abbrev: try to complete the word by looking at the history
         expand-to-file-name: try to complete the word from a file name
         forward-char: move the cursor after the next word
         forward-word: move the cursor to the next character
         interrupt: interrupt command (send control-C)
         kill-line: delete from the cursor to the end and save in buffer
         kill-word: delete the next word
         next-history: display the next line of the history
         operate-and-get-next: send line and display the next history line
         previous-history: display the previous line of the history
         quit: quit ledit
         quoted-insert: insert the next character as it is
         redraw-current-line: redisplay the current line
         reverse-search-history: backward search in the history
         suspend: suspend ledit (send control-Z)
         transpose-chars: exchange the last two characters

KNOWN BUGS

       If ledit has been launched in a shell  script,  the  suspend  command  kills  it  and  its
       command... Use "exec ledit comm" instead of "ledit comm".
       The  suspend  command stops ledit but not the called program. Do not do this if the called
       program is not waiting on standard input.
       In some systems (e.g. alpha), pasting two many characters works  bad  and  may  block  the
       terminal. Probably a kernel problem. No solution.
