       impp v0.2
------------------------------------------------------------------------


-------------------------------- About ---------------------------------

impp is an interactive command line mp3 player application. Every 
action the player can execute, is triggered by a specific command. 
Several commands are supported to enable the user to add and delete 
songs from the playlist, change the current working directory, list the
mp3 files included in it, and much more.

impp supports both filename and command autocompletion, the same way
shell interpreters do. By pressing the TAB key, depending on the 
command which is in the command line, the available filenames or 
arguments available for such command will be printed out. 

impp is licensed under the GNU General Public License version 2, as 
documented in the "COPYING" file.

------------------------------ Compiling -------------------------------

When running configure, you might want to compile impp using different
setups. impp can use both libmad and libmpg123 as decoders, as well as
portaudio and libasound to handle audio output. The default configure
script uses libmpg123 and portaudio. 

To use libmad as the mp3 decoder, add "decoder=mad" as a parameter of
this script. Moreover, to use libasound, add "output=alsa". e.g:

./configure decoder=mad output=alsa

Then just run "make" to compile impp using the libraries you chose.

------------------------------ Commands --------------------------------

This is a list of impp's currently supported commands:

- add SONG [SONG[...]]: Adds one/multiple songs to the playlist. Path's
  given can be either absolute or relative to the current working 
  directory. Note that the asterisk(*) character serves as a wilcard, so
  the user could execute "add Track*", which will add every song which 
  starts with "Track" to the playlist. Keep in mind that only .mp3 files
  will be added to the playlist, so there's no need to make this 
  explicit by using the wildcard this way: "add *.mp3". In such case,
  just use an asterisk, and every mp3 file will be added. Each time
  this command is executed, the last song added's path is stored on the
  "_" path variable.
  
- alias <[ALIAS COMMAND | del ALIAS]>: Since there are some commands 
  that will be used more than others, the user can create its own alias,
  in order to reduce the amount of characters to type for each command.
  Therefore, if the user wants to create an alias for "add", he could
  execute "alias a add". After this, songs could be added to the 
  playlist just by typing "a". Multi-word alias can be created by using 
  double quotes, e.g. 'alias shuffle "plist shuffle"'. If an alias was 
  to be removed, the "del" parameter could be used, e.g. "alias del a".
  
- audio [DEVICE]: Displays/modifies the audio device being used. This is
  useful when using ALSA output module, where one might one to use 
  another device in certain situations. e.g. "audio hw:0,0".
  
- cd <DIRECTORY_NAME>: Changes the current working directory to the
  one given as DIRECTORY_NAME. Note that if any paths have been defined,
  a '$' character must be prepended to the pathname so that impp nows
  you're refering to a defined path. e.g: "cd $music".
  
- config <save | load | poll | add >: Saves/loads the configuration file. This file
  is stored in $HOME/.impp/impp.conf, and contains a list of commands
  which will be executed when the application starts.
  The "add" and "poll" arguments modify impp's configuration paremeters.
  One can set "shuffle" and "filter" on or off using "config add shuffle on",
  for example. This way, if the configuration is saved afterwards, 
  next time impp is launched, it will startup using shuffle mode.
  
- exit: Gracefully exits the application. This same behaviour occurs 
  when impp reads EOF.

- help: Displays the supported commands and a simple description for 
  each of them.
  
- ls [PARAMS]: List files in the current/a given directory. This 
  actually forks and execs "ls", so any parameter accepted by that 
  application, can be used as an argument for this command.
  
- next: Plays the next song in the playlist, stops playing if there are
  no songs left.

- path: Lists/creates/delete a path variable. Path variables serve as
  shortcuts for long directory names. The path command alone, lists
  every already defined path variable. If the user wanted to create a
  new shortcut, then it should follow this format: "path SHCUT PATH", 
  which would create a shortcut named SHCUT, to PATH. To delete a 
  variable, the "del" parameter should be used, the same way as the
  "alias" command. e.g. "path music /home/john/Music/".
  
- pause: Pauses the player.

- play: Plays the current song in the playlist.

- plist: List/manage the playlist. This command alone lists the playlist
  and only shows within a range of 5 songs from the current. 
  
  * The "prev" parameter is used, then every song which is before the 
    current one is displayed.
    
  * The "next" parameter displays the songs which are after the current 
    one in the playlist.
    
  * The "clear" parameter erases the current playlist.
  
  * The "export" parameter stores the current playlist in a file, which 
    can be loaded with the "import" command. This file will be stored in
    the $HOME/.impp/playlist/.
    
  * The "import" parameter loads a playlist stored with the "export" 
    command. Playlists are text files containing a non-quoted list of
    mp3 files, one per line.
    
  * The "shuffle" parameter displays wether the playlist is shuffled. 
    In order to set the shuffle mode on and off, an additional "on" or
    "off" parameter should be added. e.g. "plist shuffle on".

  * The "filter" parameter displays wether the playlist allows repeated
    songs. In order to set the filter mode on and off, the mechanism 
    used is the same as the "shuffle" parameter.
    
  * The "del" parameter takes one or more integers and erases the 
    song(s) which occupies the given index(es). 

- prev: Plays the previous song in the playlist.

- prompt [NEW_PROMPT]: Displays/modifies the current prompt.

- pwd: Displays the current working directory.

- replay: Plays the current song from the beggining.

- usage <COMMAND>: Shortly displays the usage for the given command.
