NAME

       rifle - ranger's file opener

SYNOPSIS

       rifle [--help] [-f FLAGS] [-l] [-p KEYWORD] [-w PROGRAM] files

DESCRIPTION

       rifle is a powerful file executor that allows for complex file type checking, written to
       meet the needs of the file manager ranger.  rifle's strength lies in automatically
       determining file types, depending on which programs are installed on the system, even
       without any user interaction.

OPTIONS

       -f FLAGS      Specify flags for opening the files.  Flags are letters that changes how the
                     program is executed.  Any combination of flags will work.  Writing uppercase
                     flags will negate the effect of all previously used lowercase flags of the
                     same letter.

                     Table of all flags:
                      f   fork program to background
                      r   run program as root, using sudo
                      t   run program in a separate terminal, as specified by $TERMCMD

       -l            List all possible ways to open the specified files.  Each line will contain
                     information in the format of id:label:flags:command. id is the
                     identification number. label is an arbitrary string that was specified for
                     this command, flags are the flags that are used by default, and command is
                     the command that is going to be executed.

       -p KEYWORD    Pick a method to open the files.

                     KEYWORD is either the ID number listed by "rifle -l" or a string that
                     matches a label in the configuration file.

       -w PROGRAM    Open the files with the program PROGRAM

       -h, --help    Print a list of options and exit.

FILES

       rifle shares configuration files with ranger, though ranger is not required in order to
       use rifle.  The configuration file rifle.conf is expected to be at
       ~/.config/ranger/rifle.conf.

       This file specifies patterns for determining the commands to open files with.  The syntax
       is described in the comments of the default rifle.conf that ships with ranger.  To obtain
       it, you need to run: "ranger --copy-config=rifle"

ENVIRONMENT

       EDITOR  Determines which editor to use for editing files (in the default rifle.conf).

       PAGER   Determines which pager to use for displaying files (in the default rifle.conf).

       TERMCMD Determines the terminal emulator command for use with the t flag.  It is required
               that the value is the path to an executable file which accepts the "-e COMMAND"
               argument.

       XDG_CONFIG_HOME
               Specifies the directory for configuration files. Defaults to $HOME/.config.

EXAMPLES

       List all the different methods:

        $ rifle -l helloworld.py
        0:editor::"$EDITOR" -- "$@"
        1:pager::"$PAGER" -- "$@"
        2:::python -- "$1"

       Display its content by opening it with "cat":

        $ rifle -w cat helloworld.py
        print("Hello World!")

       Run it by picking the method 2, which calls 'python -- "$1"':

        $ rifle -p 2 helloworld.py
        Hello World!

       Display the file in a pager inside a new terminal, run as root:

        $ rifle -p 1 -f tr helloworld.py
