- Add advanced window matching system, capable of matching against arbitrary window properties as well as a series of internal properties, with 4 additional operators (>, <, >=, <=) useful for integer targets, and support of logical operators. The old matching system is removed, but compatibility with the format is retained. - As the new matching system is pretty complicated, and I have no past experience in writing a parser, it's pretty possible that bugs are present. It also has inferior performance, but I hope it doesn't matter on modern CPUs. - It's possible to disable matching system at compile time with NO_C2=1 now. - Add ps->o.config_file to track which config file we have actually read. Queryable via D-Bus. - Parse -d in first pass in get_cfg() as c2 needs to query X to get atoms during condition parsing. - Fix a bug in wid_get_prop_adv() that 0 == rformat is not handled correctly. - Fix incompatibility with FreeBSD sed in dbus-examples/cdbus-driver.sh . - Add recipe to generate .clang_complete in Makefile, used by Vim clang_complete plugin. - Add DEBUG_C2 for debugging condition string parsing. DEBUG_WINMATCH is still used for match debugging. - Rename win_on_wdata_change() to win_on_factor_change(). - Extra malloc() failure checks. Add const to matching cache members in session_t. Code clean-up. Documentation update. |

Compton
Compton is a compositor for X, and a fork of xcompmgr-dana.
I was frustrated by the low amount of standalone lightweight compositors. Compton was forked from Dana Jansens' fork of xcompmgr and refactored. I fixed whatever bug I found, and added features I wanted. Things seem stable, but don't quote me on it. I will most likely be actively working on this until I get the features I want. This is also a learning experience for me. That is, I'm partially doing this out of a desire to learn Xlib.
Changes from xcompmgr:
- inactive window transparency / dimming
- titlebar/frame transparency (specified with
-e) - menu transparency (thanks to Dana)
- shadows are now enabled for argb windows, e.g. terminals with transparency
- removed serverside shadows (and simple compositing) to clean the code, the only option that remains is clientside shadows
- configuration files (see the man page for more details)
- colored shadows (
--shadow-[red/green/blue]) - a new fade system
- VSync support (not always working)
- Blur of background of transparent windows, window color inversion (bad in performance)
- Some more options...
Fixes from the original xcompmgr:
- fixed a segfault when opening certain window types
- fixed a memory leak caused by not freeing up shadows (from the freedesktop repo)
- fixed the conflict with chromium and similar windows
- many more

How to build
To build, make sure you have the dependencies above:
# Make the main program
$ make
# Make the man pages
$ make docs
# Install
$ make install
(Compton does include a _CMakeLists.txt in the tree, but we haven't decided whether we should switch to CMake yet. The Makefile is fully usable right now.)
Known issues
-
VSync does not work too well. It's widely reported that tearing still happens on the top of the screen. I do not know how to fix the issue.
-
If
--unredir-if-possibleis enabled, when compton redirects/unredirects windows, the screen may flicker. Using--paint-on-overlayminimizes the problem from my observation, yet I do not know if there's a cure. -
compton may not track focus correctly in all situations. The focus tracking code is experimental.
--use-ewmh-active-winmight be helpful. -
Compton may give ugly shadow to windows with ARGB background if
-zis enabled, because compton cannot determine their real shapes. One may have to disable shadows on those windows with window-type-specific settings in configuration file or--shadow-exclude. -
The performance of blurring is terrible, probably because of a problem in the X Render implementation. Its behavior is driver-dependent: With nvidia-drivers it works but there are strange 1px lines remaining when you operate on windows (not sure if it's a bug in compton or in the driver); with nouveau it's utterly broken.
Usage
Please refer to the Asciidoc man pages (man/compton.1.asciidoc & man/compton-trans.1.asciidoc) for more details and examples.
Note a sample configuration file compton.sample.conf is included in the repository.
Support

Bug reports and feature requests should go to the "Issues" section above.
-
Our (semi?) official IRC channel is #compton on FreeNode.
-
Some information is available on the wiki, including (and presently, only includes) a FAQ.
License
Although compton has kind of taken on a life of its own, it was originally an xcompmgr fork. xcompmgr has gotten around. As far as I can tell, the lineage for this particular tree is something like:
- Keith Packard (original author)
- Matthew Hawn
- ...
- Dana Jansens
- chjj and richardgv
Not counting the tens of people who forked it in between.
Compton is distributed under MIT license, as far as I (richardgv) know. See LICENSE for more info.
