<title>Description</title>
<para>Conky is a system monitor for X originally based on torsmo.
Since its inception, Conky has changed significantly from its
predecessor, while maintaining simplicity and configurability. Conky
can display just about anything, either on your root desktop or in its
own window. Not only does Conky have many built-in objects, it can
also display just about any piece of information by using scripts and
other external programs.</para>
<para>Conky has more than 250 built in objects, including support for
a plethora of OS stats (uname, uptime, CPU usage, mem usage, disk
usage, "top" like process stats, and network monitoring, just to name
a few), built in IMAP and POP3 support, built in support for many
popular music players (MPD, XMMS2, Audacious), and much much
more. Conky can display this info either as text, or using simple
progress bars and graph widgets, with different fonts and
colours.</para>
<para>We are always looking for help, whether its reporting bugs,
writing patches, or writing docs. Please use the facilities at
SourceForge to make bug reports, feature requests, and submit patches,
or stop by #conky on irc.freenode.net if you have questions or want to
contribute.</para>
<para>Thanks for your interest in Conky.</para>

<title>Compiling</title>
<para>For users compiling from source on a binary distro, make sure
you have the X development libraries installed (Unless you configure
your build without X11). This should be a package along the lines of
"libx11-dev" or "xorg-x11-dev" for X11 libs, and similar "-dev" format
for the other libs required (depending on your build options). You
should be able to see which extra packages you need to install by
reading errors that you get from running `cmake'. The easiest way to
view the available build options is to run `ccmake' or `cmake-gui'
from the source tree, but be careful when disabling certain features
as you may lose desired functionality. E.g., with BUILD_MATH disabled
you won't get errors but logarithmic graphs will be normal graphs and
gauges will miss their line.</para>
<para>Conky has (for some time) been available in the repositories of
most popular distributions. Here are some installation instructions
for a few:</para>
<para>Gentoo users -- Conky is in Gentoo's Portage... simply use
"emerge app-admin/conky" for installation.</para>
<para>Debian, etc. users -- Conky should be in your repositories, and
can be installed by doing "aptitude install conky".</para>
<para>Example to compile and run Conky with default components (note
that some build options may differ for your system):</para>

<para>Conky has been tested to be compatible with C99 C and C++0x C++,
however it has not been tested with anything other than gcc, and is
not guaranteed to work with other compilers.</para>
<para>TIP: Try configuring Conky with `ccmake' or `cmake-gui' instead
of just `cmake'.</para>

<title>You Should Know</title>
<para>Conky is generally very good on resources. That said, the more
you try to make Conky do, the more resources it is going to
consume.</para>
<para>An easy way to force Conky to reload your
<filename>~/.config/conky/conky.conf</filename>: "killall -SIGUSR1
conky". Saves you the trouble of having to kill and then
restart.</para>
</refsect1>
<refsect1>
<title>Options</title>
<para>Command line options override configurations defined in
configuration file.</para>&command_options;</refsect1>
<refsect1>
<title>Configuration Settings</title>
<para>Default configuration file location is
<filename>~/.config/conky/conky.conf</filename>&#160;or
<filename>${sysconfdir}/conky/conky.conf</filename>. On most systems,
sysconfdir is /etc, and you can find the sample config file there in
<filename>/etc/conky/conky.conf</filename>.</para>
<para>You might want to copy it to
<filename>~/.config/conky/conky.conf</filename>&#160;and then start modifying
it. Other configs can be found at
<filename>
https://github.com/brndnmtthws/conky</filename>.</para>&config_settings;</refsect1>
<refsect1>
<title>Objects/Variables</title>
<para>Colours are parsed using XParsecolor(), there might be a list of
them:
<filename>/usr/share/X11/rgb.txt</filename>. Colour can be also in #rrggbb
format (hex).</para>
<para>Some objects may create threads, and sometimes these threads will
not be destroyed until Conky terminates. There is no way to destroy or
clean up threads while Conky is running. For example, if you use an MPD
variable, the MPD thread will keep running until Conky dies. Some threaded
objects will use one of the parameters as a 'key', so that you only have 1
relevant thread running (for example, the $curl, $rss and $weather objects
launch one thread per URI).</para>&variables;</refsect1>
<refsect1>
<title>Lua API</title>
<para>Conky features a Lua Programming API, and also ships with Lua
bindings for some useful libraries. Note that the bindings require
tolua++, which currently only compiles against Lua 5.1.</para>
<para>To use Lua Conky, you first need to make sure you have a version of
Conky with Lua support enabled (``conky -v'' will report this). Conky
defines certain global functions and variables which can be accessed from
Lua code running in Conky. Scripts must first be loaded using the lua_load
configuration option. You then call functions in Lua via Conky's $lua,
$lua_read, and Lua hooks.</para>
<para>Be careful when creating threaded objects through the Lua API. You
could wind up with a whole bunch of threads running if a thread is created
with each iteration.</para>
<para>At this time, the Lua API should not be considered stable and may
change drastically from one release to another as it matures.</para>
<para>NOTE: In order to accommodate certain features in the cairo
library's API, Conky will export a few additional functions for the
creation of certain structures. These are documented
below.</para>&lua;</refsect1>

<title>Bugs</title>
<para>Drawing to root or some other desktop window directly doesn't
work with all window managers. Especially doesn't work well with Gnome
and it has been reported that it doesn't work with KDE either.
Nautilus can be disabled from drawing to desktop with program
gconf-editor. Uncheck show_desktop in /apps/nautilus/preferences/.
There is -w switch in Conky to set some specific window id. You might
find xwininfo -tree useful to find the window to draw to. You can also
use -o argument which makes Conky to create its own window. If you do
try running Conky in its own window, be sure to read up on the
own_window_type settings and experiment.</para>
