Ubuntu Manpage: lpe - Lightweight programmer's editor

NAME

       lpe - Lightweight programmer's editor

SYNOPSIS

       lpe [ --help | --version ]
       lpe [--mode <mode>] [ -- ] file

DESCRIPTION

       Lpe  is  a  small,  fast,  visual  text  editor  designed to make editing code easier.  It
       provides simultaneously all the features that may be required in a good code editor  while
       preserving a light and intuitive feel that makes it nice to use.

   Options
       --help Prints a brief description of program usage and terminates.  This must be the first
              option to lpe, and all other options are ignored.

       --version
              Prints a message indication the program version and terminates.  This must  be  the
              first option to lpe, and all other options are ignored.

       --mode Sets  the buffer mode to the one specified, instead of scanning for a suitable mode
              from those available.

       --     Treat future arguments as file names, not options.  This allows lpe to be  used  to
              edit files starting with the - character.

NOTES

       What  follows  are  the  control key functions for lpe.  Arrow keys, home, end, backspace,
       delete and the like all do as they would be expected to do.  Some control keys  are  bound
       to  the  same function as some standard movement keys, such as home or page down.  This is
       because the more intuitive keys may not be available on some systems.

       Ctrl-V Ctrl-V
              Pass the entire buffer through a shell command

       Ctrl-V Ctrl-A
              Pass the entire buffer through an awk script

       Ctrl-V Ctrl-S
              Pass the entire buffer through a sed script

       Ctrl-V Ctrl-B
              Pass several lines of the buffer through a shell command

       Ctrl-V Ctrl-D
              Pass several lines of the buffer through an awk script

       Ctrl-V Ctrl-F
              Pass several lines of the buffer through a sed script

       Ctrl-D Perform an internal debug command

       Ctrl-X Write the buffer to disk and exit

       <interrupt>
              Exit without writing to disk

       Ctrl-Z Suspend the editor and escape to a prompt

       Ctrl-L Erase and redraw the entire screen

              <interrupt> refers to your terminal's interrupt key.  This is often Ctrl-C, but can
              vary  between  terminals.   Ctrl-Z,  on the other hand, is fixed, regardless of the
              normal stop key for your terminal.

MODULES

Although lpe is meant to be small, it has the capability of performing more advanced
actions through a feature known as buffer modes. Buffer modes allow lpe to act
differently according to the programming language in the current buffer. They are
implemented through language modules, which are loaded at run-time by lpe to handle
buffers that they apply to.

All language modules should be placed in a module repository directory. These directories
are set by the LPE_MODULE_PATH environment variable, which should be a colon-separated
list of directories (similar to PATH). If this variable is not set, then lpe scans for
modules in the following locations, and in this order:

$HOME/.lpe /usr/local/lib/lpe /usr/lib/lpe /etc/lpe

Note that the /etc/lpe directory is old, obsolete, and non-standard. It should not be
used to hold modules. As modules are binary files and are specific to the architecture
that uses them, they should be properly placed in the lib directories listed above.

These locations are scanned at run-time, and any regular files in them are interpreted as
potential language modules for use by lpe. Subdirectories will not be scanned. A buffer
will be assigned the first mode found that applies to that file, so for example a mode in
a user's home directory will override one in the system-wide lib directory.

BUGS

       Lots of 'em -- see the BUGS file in the  distribution  for  a  partial  list.   I  am  not
       planning  on  updating this man page often enough to keep up with the bug list, so I won't
       even try to list bugs here.
