NAME

       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.

       -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

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.
