You can run ranger without installing by simply starting the executable
file ranger.py in the top directory of this package.


To install ranger, follow this instructions:

0. Make sure you have a recent version of python, including the
   curses module, which is the case if this shell command prints no errors:
   python -c 'import curses'


1. Copy the file "ranger.py" into any of the directories in the PATH
   environment variable, for example to "/usr/bin/ranger"


2. Copy the directory "ranger" into one of the python module search
   paths, for example to "/usr/lib/python2.6/site-packages/ranger".

   Ensure that the path is listed by the command:
   python -c 'import sys; print("\n".join(sys.path))'


3. Optionally, you can activate an extra feature: When you exit ranger,
   the directory of the current shell can be changed to the last visited
   directory in ranger.  To do so, add this alias to your shell rc file:

   alias rng="source ranger ranger"

   (Unfortunately this feature is shell dependent.  It has been
   successfully tested with BASH only.)
Ranger v.1.0.4
==============

Ranger

   A keeper, guardian, or soldier who ranges over a region
   to protect the area or enforce the law.

This is the filemanager Chuck Norris the Texas Ranger would use
if he had a computer with a unix-like operating system.  (He doesn't
trust computers though and prefers to do the calculations himself.)

After all, as a professional ranger, he needs a broad overview of his
territory, and the multi-column display of ranger provides just that,
rather than restricting you to the current directory only.
You can preview the content of the selected file or directory, copy or move
files around with the VIM-like commands dd and yy, execute predefined
applications when opening a file, etc...

Everything is fully customizable and written in Python (2.6 and 3.1
compatible) using curses for the text-based user interface.

Bugs and Feature Requests

Alternatively you can send an email to romanz@lavabit.com.

Please include as much relevant information as possible.
Using ranger with the --debug option will abort the program and
print tracebacks rather than a red message in the statusbar.
If this applies to you, please include such a traceback in your report.


Getting Started
---------------

If you just want to check out ranger without installing it, type

    ./ranger.py --clean

in the top directory of ranger.  By using the --clean switch, it will
leave no trace on your system whatsoever.

To properly install it, follow the instructions in the INSTALL file,
then type:

    ranger

You should see 4 columns.  The third is the directory where you are at
the moment.  To the left, there are the directories above the current
working directory, and the column on the right is a preview of the selected
file/directory.

Now use the arrow keys to navigate, press enter to open a file.

A list of commands with short descriptions can be viewed by
pressing "?" inside the program and following the instructions.
The file ranger/defaults/keys.py contains all key combinations, so that's
another place you may want to check out.


Opening Files with Ranger
-------------------------

If you use the same applications like me, you'll be able to open
files by pressing the right arrow key.  If not, you will have to
specify them in ranger/defaults/apps.py.  It's explained
in the docstrings how exactly to do that.

Once you've set up your applications, you can also use ranger to
open files from the shell:
    ranger blabla.pdf


Customizing Ranger
------------------

The file ranger/defaults/options.py contains most of the options.
apps.py defines how files are run, keys.py defines keybindings.

The files in ranger/defaults/ can be copied into ~/.ranger/ for per-user
modifications.  Colorschemes can be placed in ~/.ranger/colorschemes.

The configuration files should be self-explanatory.  If you need more
information, check out the source code.

Also, see the file HACKING for more detailed instructions on
modifying the program.


Tips
----

Change the directory of your parent shell when you exit ranger:

ranger() {
    $(which ranger) $@ &&
    cd "$(grep \^\' ~/.ranger/bookmarks | cut -b3-)"
}

This can be put into your ~/.bashrc or something similar.
