FEP(1L)             UNIX Programmer's Manual              FEP(1L)

NAME
     fep - general-purpose front end processor

SYNOPSIS
     fep [-emacs|-vi] [-h history-length] [-p prompt] UNIX-
     command

DESCRIPTION
     Fep is a general purpose front end processor applicable to
     most UNIX commands that features vi(1)- or emacs(1)-like
     line editing and a command history mechanism like that of
     csh(1).

     Choice of editing style is made by selecting either the
     emacs mode or the vi mode (named for the editors they emu-
     late), specified either by command line option or by setting
     a variable interactively or in the start-up file.

     The default key bindings are shown below for both edit
     modes.  These can be customized using the bind-to-key Com-
     mand.

     Emacs Bindings

     Here follow the default key bindings for the emacs mode.
     Each function name should be self-explanatory.  The function
     names are defined as similarly to Gosling's emacs as possi-
     ble.

     Vi bindings

     The vi mode has two sub-modes, the command mode and the text
     insert mode.  The commands of vi emulated as correctly as
     possible.  Here is a list of the default key bindings of the
     vi mode that differ from normal vi commands.

          ^A             expand-file-name
          ^L             list-file-name
          ^N             next-history

          ^X-^C          terminate
          ^X-^D          send-eof

     Built-in commands

     Fep has some built-in commands that are not passed to child
     process but understood and processed by fep itself.  These
     commands can be issued from the terminal or start-up file.

        bind-to-key function-name binding-key
             Change key bindings.  For example, to bind the func-
             tion list-file-name to the string "^X-^X", type the
             following:
                  bind-to-key list-file-name "\^X\^X"

        fep-alias
        fep-alias name
        fep-alias name string
             The first form print all aliases.  The second form
             print alias for name.  The last form set string as
             an alias of name.

             As mentioned in BUGS, executing more(1) from fep is
             not allowed.  So next alias is usefull.
                  if $command == sh
                       fep-alias more "fep-command more"
                       fep-alias vi "fep-command vi"
                  endif

        fep-unalias list
             Remove alias name for each word in list.

        fep-set variable = value
             Set a variable of fep to some value.

        fep-unset variable
             Unset a variable.

        fep-cd [ directory ]
        fep-chdir [ directory ]
             Change directory.  It sometimes happens that a child
             process has changed directory, but fep is still in
             old directory.  In such a case, neither list-file-
             name nor expand-file-name will function as expected.
             This command allows you to change fep's current
             working directory (default = home directory).

        fep-pwd
             Print fep's current working directory.

        fep-history [ number of history ]
             Show the history of commands under fep.

        fep-echo arguments
             Only print the arguments.  Variable names can be
             used prefixed by the "$" character.

        fep-source file
             Read the specified file and execute it.  The con-
             tents of the file are not sent to sub-processes.

        fep-save-history [ number of saved history ] file
             Save the current history buffer to a specified file.

        fep-read-history  [ file ]
             Read in the command history from a specified file.

             Default is the value of the history-file variable.
             This file name is understood as a path relative to
             the home directory.  If you want to specify the name
             relative to the current directory instead, prefix
             the path by "./".

        fep-command command
        fep-! command
             Execute command.

        quit-fep
             Kill the sub-process and exit.

        pause-fep
        stop-fep
        suspend-fep
             Suspend fep itself.  In the unlikely possibility
             that fep falls into a dead-lock in which the sub-
             processes have stopped but fep is still running, use
             one of these commands to escape from the situation.

        fep-read-from-file file
        fep-< file
             Read data from specified file and send them to sub-
             process.  Sub-process read the data from the file as
             if they are typed from keyboard.

        fep-read-from-command command
        fep-<! command
             Send output of specified command to sub-process.

        show-bindings
             Print current binding information.

     Control structures

        fep-if expression
        fep-elseif expression
        fep-else
        fep-endif
             Only four control structures are supported but that
             seems enough.  Expression allows only the two opera-
             tors "==" and "!=".
             Variables can be referenced by prefixing with the
             "$" character.

        Note: The "fep-" prefix of the built-in functions and the
        above operators can be abbreviated in commands that fep
        executes from a file.

FEP(1L)             UNIX Programmer's Manual              FEP(1L)

     Lines starting with the character "#" are ignored by fep.
     If fep encounters a comment in interaction, it is sent to
     the sub-process.  In reading from a file, comments will
     merely be ignored.

     Variables

     Fep uses some variables.

        editmode                      default: emacs
             This variable defines the mode for command line
             editing.  Key bindings will be set for the appropri-
             ate defaults when this variable is changed.  Fep
             first looks at the environment variable EDITMODE,
             then looks at any command line arguments, and
             finally reads in the .feprc start-up file.

        expand-tilde                  default: on
             Fep expands "~" to the real home directory name by
             the expand-file-name function when this variable is
             set.

        ignore-empty-line             default: on
             If this variable is set, empty command lines are not
             saved to the history file.

        ignore-same-line              default: on
             If this variable is set, command lines identical to
             the previous command line are not saved to the his-
             tory file.

        alarm-on-eof                  default: on
             If this variable is set AND the function send-eof is
             not bound to the eof character AND the variable
             ignore-eof is not set, an alarm message will be
             displayed once the first time eof is encountered on
             an empty line.

        history                       default: 100
             Fep maintains a history file of the length specified
             by this variable.

        savehist                      default: off
             If savehist is set fep saves the number of history
             entries specified by value of this variable to the
             file named in the variable history-file on terminat-
             ing.

        history-file                  default: .fephistory
             Contains the name of the history file for reading
             from and saving to.  If the file described by this
             variable exists, fep will read the file into the

             session's history when it exits.

        showhist                      default: 20
             This variable specifies the number of history lines
             to be displayed by the show-history function.

        ignore-eof                    default: off
             Fep never worries about the eof character if this
             variable is set.

        command                       default: command-name
             Fep set this variable to the command name of the
             sub-process when it starts up.

        shell                         default: /bin/sh
             Describe the command name to be invoked by invoke-
             shell.

        prompt                        default: NULL
             Fep outputs a prompt after destroying the command
             line to execute built-in functions.  The default
             string is set to the NULL string, but there are some
             default prompt strings for some common commands such
             as sh, dbx, lpc, mail, sendmail -bt and calc. How-
             ever, since fep doesn't care about what program is
             running, the same prompt is still output when you
             are executing bc from sh.
             You can change the value of prompt and other vari-
             ables in the start-up file as follows:
                  if $command == sh
                       set prompt = "$ "
                  endif

     Start-Up File

     Fep executes the file ".feprc" in the home directory of the
     user if it is found there when starting up.  It looks for
     arguments on the command line first, and only then reads the
     ".feprc" file, so the file has higher priority.

     Probably only the function name "toggle-transparency" is
     hard to understand.  This function is provided for entering
     non-line-oriented tools from a line-oriented tool using fep.
     Assume a situation where you are using sh(1) with fep, and
     then invoke vi(1).  Since fep intercepts all input for edit-
     ing, vi cannot work correctly.  You can escape from this
     annoying situation using the "toggle-transparency" function
     which is bound to the Control-^ key by default.  Of course
     it is also necessary to return to the normal mode after
     exiting vi.

BUGS
     Sometimes working on the program the author lost his mind,
     whereupon so did the program.

     Why doesn't this work as a front end for csh?!

     Please don't use more with fep.  Since more reads input from
     stderr, it is impossible to know which process, fep or more,
     will catch the terminal input.
