   subsystem (e.g. "net: add localAddress and localPort to Socket").
2. Keep the second line blank.
3. Wrap all other lines at 72 columns.

A good commit log looks like this:

```
subsystem: explaining the commit in one line

Body of commit message is a few lines of text, explaining things
in more detail, possibly giving some background about the issue
being fixed, etc etc.

The body of the commit message can be several paragraphs, and
please do proper word-wrap and keep columns shorter than about
72 characters or so. That way `git log` will show things
nicely even when it is indented.
```

The header line should be meaningful; it is what other people see when they
run `git shortlog` or `git log --oneline`.

          where it doesn't:

          - Paths in ramdisk volumes created by tools which sidestep the Volume Manager (such as ImDisk)
            cannot be resolved.
          - Inconsistent casing when using drive letters.
          - Resolved path bypasses subst'd drives.

        While this function can still be used, it's not recommended if scenarios such as the
        above need to be supported.

        The background story and some more details on these issues can be checked
        `here <https://github.com/nodejs/node/issues/7726>`_.

    .. note::
      This function is not implemented on Windows XP and Windows Server 2003.
      On these systems, UV_ENOSYS is returned.

some number crunching before to use the processor to the maximum) and grab the
data. It is **asynchronous** because the application expressed interest at one
point, then used the data at another point (in time and space). It is
**non-blocking** because the application process was free to do other tasks.
This fits in well with libuv's event-loop approach, since the operating system
events can be treated as just another libuv event. The non-blocking ensures
that other events can continue to be handled as fast as they come in [#]_.

.. NOTE::

    How the I/O is run in the background is not of our concern, but due to the
    way our computer hardware works, with the thread as the basic unit of the
    processor, libuv and OSes will usually run background/worker threads and/or
    polling to perform tasks in a non-blocking manner.

Bert Belder, one of the libuv core developers has a small video explaining the
architecture of libuv and its background. If you have no prior experience with
either libuv or libev, it is a quick, useful watch.

libuv's event loop is explained in more detail in the `documentation
<http://docs.libuv.org/en/v1.x/design.html#the-i-o-loop>`_.

Remember to call ``uv_tty_reset_mode`` when your program exits to restore the
state of the terminal. Just good manners. Another set of good manners is to be
aware of redirection. If the user redirects the output of your command to
a file, control sequences should not be written as they impede readability and
``grep``. To check if the file descriptor is indeed a TTY, call
``uv_guess_handle`` with the file descriptor and compare the return value with
``UV_TTY``.

Here is a simple example which prints white text on a red background:

.. rubric:: tty/main.c
.. literalinclude:: ../../code/tty/main.c
    :linenos:
    :emphasize-lines: 11-12,14,17,27

The final TTY helper is ``uv_tty_get_winsize()`` which is used to get the
width and height of the terminal and returns ``0`` on success. Here is a small
program which does some animation using the function and character position
escape codes.

The escape codes are:

======  =======================
Code    Meaning
======  =======================
*2* J    Clear part of the screen, 2 is entire screen
H        Moves cursor to certain position, default top-left
*n* B    Moves cursor down by n lines
*n* C    Moves cursor right by n columns
m        Obeys string of display settings, in this case green background (40+2), white text (30+7)
======  =======================

As you can see this is very useful to produce nicely formatted output, or even
console based arcade games if that tickles your fancy. For fancier control you
can try `ncurses`_.

.. _ncurses: http://www.gnu.org/software/ncurses/ncurses.html

.. versionchanged:: 1.23.1: the `readable` parameter is now unused and ignored.
                    The appropriate value will now be auto-detected from the kernel.
