       le - full screen text editor

SYNOPSIS

       le [options] filename

DESCRIPTION

       le  is  a text editor which offers wide range of capabilities with a simple interface. It has a pull down
       menu and a simple help system to get started. See KEYS section below to learn about key combinations.

       Among its features there are: various operations with stream and rectangular blocks, search  and  replace
       with  full  regular  expressions, text formatting, undelete/uninsert, hex editing, tunable key sequences,
       tunable colors, tunable syntax highlighting.

       The editor currently supports only one loaded file at a time.

KEYS

       Here are some starting hints:

       F10 or C-n
              menu

       F1     help

       C-x    exit (cancel)

       Arrows navigate

       In the editor the following key description is used:

       Key1-Key2
              simultaneous key1 and key2 press

       Key1+Key2
              sequential keys press

       Key1 | Key2
              press Key1 OR Key2

       ^Key   Ctrl-Key

       ~Key   Shift-Key

       ^~Key  Ctrl-Shift-Key | Alt-Key

       Some of ^Fx, ~Fx, ^~Fx can be typed as ESC+Fx.

       The rest of key combinations can be seen in help, in menu and in the keyboard map  (default  one  can  be
       seen with le --dump-keymap).

       There  is  support  for  block filtering through an external program, a command output read-in, writing a
       block through a command. To read or write block from/to a command, use F4+R or F4+W and file name of  the
       following format: ``|command args''. Filtering is achieved by F4+| followed by command name.

STATUS LINE

       On the status line you can see current line, column, the size of loaded file, the code of character under
       cursor, several one letter flags, file name, offset in bytes from the file beginning and percent position
       in the file.

       One  letters flags are: * - modified; R - Russian keyboard (works only on certain terminals); I - insert,
       O - overstrike; A - autoindent; D - dos style line terminators (CR  NL);  U  -  undelete  possible,  u  -
       uninsert possible; B - column block mode.

TEXT PROTECTION

       To   prevent   changes   loss   on   crash,   le  regularly  dumps  the  editing  text,  if  changed,  to
       ~/.le/tmp/FILENAME.PID , where FILENAME is the file name with slashes converted to underlines; PID is the
       process id of the editor process.

       When  the  editor gets a fatal signal, it also dumps the text, to ~/.le/tmp/DUMP-SIG-FILENAME.PID , where
       SIG is the signal number.

OPTIONS

       -r, --read-only
              Work as viewer, don't allow changes. If your system supports mmap(2), it will be used to get  file
              contents to memory.

       -h, --hex-mode
              Start in hex mode

       --mmap Use  mmap(2)  to  load  file read-only. Can be used to view very large files or even devices. This
              implies -h.

       --mmap-rw
              Use mmap(2) to load file read-write in MAP_SHARED  mode.  Use  with  caution  --  the  changes  go
              directly to file or disk, no undo. In this mode only replace can be used, but it allows editing of
              very large files or even devices.  This implies -h.

       --multibyte
              Force multibyte mode on. Multibyte mode is usually enabled automatically as needed.

       --no-multibyte
              Force multibyte mode off, even if it was automatically determined that it should be on.

       -b, --black-white
              Start in black & white mode

       -c, --color
              Start in color mode

       --dump-keymap
              Dump default keymap to stdout and exit

       --dump-colors
              Dump default color map to stdout and exit

       --version
              Print the version of LE and exit

       --help Print short description of options and exit

ENVIRONMENT VARIABLES

       The following environment variables are processed by le:

       HOME   Used for tilde (`~') expansion.

       LE_DEFAULT_EOL
              The default EOL marker. It can be set to NL (\n), CRNL (\r\n) or CR (\r).  Also it can be  set  to
              any other 1-2 character string interpreted literally.

       TERM, LINES, COLUMNS
              These variables are used by curses library for full-screen output.

FILES

       DATADIR/colors
       ~/.le/colors
       DATADIR/colors-$TERM
       ~/.le/colors-$TERM
              Color  palette description. Those files are sequentially read and color definitions in later files
              have higher precision.

       ~/.le/keymap-$TERM
       DATADIR/keymap-$TERM
       ~/.le/keymap
       DATADIR/keymap
              Key map descriptions. Only the first existing file is read.

       ~/.le/term-$TERM
       DATADIR/term-$TERM
              Terminal specific options. Only the first existing file is read.  Use  Options->Terminal  menu  to
              tune the options.

       ./.le.ini
       ~/.le/le.ini
       DATADIR/le.ini
              Options. Only the first existing file is read. Use menu Options to tune these.

       .le.syntax
       ~/.le/syntax
       DATADIR/syntax
              Syntax  highlighting rules.  Only the first existing file is read. There is no default built-in in
              the editor, so if those files are not present you won't see any syntax highlighting.

       ~/.le/mainmenu
       DATADIR/mainmenu
              Main editor menu. It has simple text format. Only the first existing file is read.

       ~/.le/history
              Various histories are saved here. Do not edit by hand.

       DATADIR is determined at compile time by configure script (pkgdatadir variable). By default it has  value
       /usr/local/share/le.
