        What is this?
        =============
        
        Shell history is useful.  But it can be more useful if it logs more
        data points.  For example, if you forget which `make` target to run
        for certain project, you'd want to search shell commands that are
        run in particular directory.  Wouldn't it be nice if you can do this?::
        
           rash search --cwd . "make*"
        
        RASH records many data points and they are stored in SQLite database.
        Here is a list of recorded information [#]_.
        
        #. Current directory (``$PWD``).
        #. Exit code (``$?``)
        #. Exit code of pipes (``$PIPESTATUS`` / ``$pipestatus``)
        #. The time command is started and terminated.
        #. Environment variable (``$PATH``, ``$SHELL``, ``$TERM``, ``$HOST``, etc.)
        #. Real terminal.  ``$TERM`` is used to fake programs.
           RASH can detect if you are in tmux, byobu, screen, gnome-terminal, etc.
        #. Session information.  If you go back and forth in some terminals,
           RASH does not loose in which sequence you ran the commands in which
           terminal.
        
        .. [#] If you are curious, checkout ``rash record --help``.
        
        
        RASH also has interactive search interface.  You can see the search
        result as you type.  If you are using zsh, you can execute the result
        instantaneously.

        Install
        =======
        
        RASH is written in Python.  The easiest way to install is to use `pip`
        (or `easy_install`, if you wish).  You may need `sudo` for installing
        it in a system directory.::
        
           pip install rash
           pip install percol  # if you want interactive search feature
        
        If you use virtualenv to install RASH, you may have trouble when
        switching environment.  In that case, it is safe to make an alias
        to full path of the rash executable.::
        
          alias rash="PATH/TO/VIRTUALENV/bin/rash"
        
        If you want to use developmental version, just clone the git repository
        and add the following in your RC file.::
        
          alias rash="PATH/TO/RASH/rash_cli.py"
        
        
        Setup
        =====
        Add this to your `.zshrc` or `.bashrc`.  That's all.::
        
           eval "$(rash init)"
        
        For more information, see ``rash init --help``.
        
        
        Usage
        =====
        
        Searching history -- ``rash search``
        ------------------------------------
        
        After your shell history is accumulated by RASH, it's the time to
        make use of the history!  See ``rash search --help`` for detailed
        information.  Here is some examples.
        
        Forget how to run automated test for the current project?::
        
           rash search --cwd . --include-pattern "*test*" --include-pattern "tox*"
        
        All git commands you ran in one week.::
        
           rash search --time-after "1 week ago" "git*"
        
        Some intensive task you ran in the current project that succeeded and
        took longer than 30 minutes.::
        
           rash search --cwd-under . --include-exit-code 0 --duration-longer-than 30m
        
        **NOT IMPLEMENTED**
        What did I do after `cd`-ing to some directory?::
        
           rash search --after-context 5 "cd SOME-DIRECTORY"
        
        All failed commands you ran at this directory.::
        
           rash search --cwd . --exclude-exit-code 0
        
        Count number of commands you ran in one day::
        
           rash search --limit -1 --no-unique --time-after "1 day ago" | wc -l
        
        
        Showing detailed information -- ``rash show``
        ---------------------------------------------
        
        If you give ``--with-command-id`` to ``rash search`` command, it prints out
        ID number for each command history.::
        
           % rash search --with-command-id --limit 5 "*git*"
            359  git log
           1253  git help clone
           1677  git help diff
           1678  git diff --word-diff
           1780  git merge
        
        You can see all information associated with a command with
        ``rash show`` command::
        
           rash show 1677
        
        
        Interactive search -- ``rash isearch``
        --------------------------------------
        
        Searching history using command line is not fast.
        You can use ``rash isearch`` command to interactively search
        history and see the result immediately as you type.
        
        You need percol_ to use this feature.
        
        Zsh user can setup a keybind like this::
        
          # Type `Ctrl-x r` to start isearch
          bindkey "^Xr" rash-zle-isearch
        
        Defining this function in your rc file can be handy and it is
        usable for bash users.::
        
          rash-isearch(){
            eval "$(rash isearch)"
          }

        Dependency
        ==========
        
        RASH tested against Python 2.6, 2.7 and 3.2.  However, as some
        dependencies are not Python 3 compatible, some functionality is
        missing when used with Python 3.
        
        Python modules:
        
        * watchdog_ [#nopy3k]_
        * parsedatetime_ [#nopy3k]_
        
        .. _watchdog: http://pypi.python.org/pypi/watchdog/
        .. _parsedatetime: http://pypi.python.org/pypi/parsedatetime/
        
        .. [#nopy3k] These modules do not support Python 3.
                     They are not installed in if you use Python 3
                     and related functionality is disabled.
        
        Platforms
        ---------
        
        UNIX-like systems
          RASH is tested in Linux and I am using in Linux.
          It should work in other UNIX-like systems like BSD.
        
        Mac OS
          I guess it works.  Not tested.
        
        MS Windows
          Probably no one wants to use a shell tool in windows, but I
          try to avoid stuff that is platform specific.  Only the
          daemon launcher will not work on Windows but there is several
          ways to avoid using it.  See ``rash init --help``.
        
        Shells
        ------
        
        RASH currently supports zsh and bash.
        
        
        Design principle
        ================
        
        RASH's design is focused on sparseness.  There are several stages
        of data transformation until you see the search result, and they
        are done by separated processes.
        
        First, ``rash record`` command dumps shell history in raw JSON record.
        This part of program does not touches to DB to make process very fast.
        As there is no complex transformation in this command, probably in the
        future version it is better to rewrite it entirely in shell function.
        
        Second, ``rash daemon`` runs in background and watches the directory to
        store JSON record.  When JSON record arrives, it insert the data into
        database.
        
        ``rash record`` and ``rash daemon`` are setup by simple shell snippet
        ``eval $(rash init)``.
        
        Finally, you can search through command history using search interface
        such as `rash search`.  This search is very fast as you don't read
        all JSON records in separated files.
        
        ::
        
           +-------+         +--------+         +--------+         +--------+
           | Shell |         | Raw    |         | SQLite |         | Search |
           | hooks |-------->| JSON   |-------->|   DB   |-------->| result |
           +-------+         | record |         +--------+         +--------+
                             +--------+
        
                   `rash record`      `rash daemon`      `rash search`
                                                          `rash show`
        
                   \------------------------------/      \------------/
                      `rash init` setups them           search interface
