- Some WMs don't respect Keith Packard's proposal of
_NET_WM_WINDOW_OPACITY, and do not copy _NET_WM_OPACITY attribute of a
client window to its frame windows, thus cause opacity set by
non-override-redirect windows to have no effect. This commit adds
support for reading _NET_WM_OPACITY from client windows if running
with --detect-client-opacity. Thanks to pvanek for reporting.
- Change Makefile logic to determine options from 3 variables
(NO_LIBCONFIG, NO_REGEX_PCRE, NO_REGEX_PCRE_JIT) instead of CFG to
ensure compatibility when we add new options. CFG variable is no
longer been respected.
- Optionally detect shaped windows using X Shape extension and disable
shadow on them with --shadow-ignore-shaped.
- Some windows are bounding-shaped just to support rounded corners, like
Chromium windows (when system titlebar is disabled in its settings).
Add --detect-rounded-corners to treat them as non-shaped windows (thus
enable shadow on them). The algorithm I use is not perfect and wrong
detection results are pretty possible to appear.
- Many windows don't use X Shape extensions to add shapes but use ARGB
background instead. These windows could only be blacklisted with
--shadow-blacklist.
- Rename a few functions. Code clean up.
- Fix compilation failure with <libpcre-8.20 and <libconfig-1.4. Tested
with libpcre-8.12 and libconfig-1.3.2, but not extensively tested.
libconfig-1.3* probably has more limitations on configuration file
syntax (enforces comma at the end of a setting?) and does not support
@include.
- Make it possible to turn off PCRE and libconfig support using
environment variable "CFG". Not well tested. CMake might provide a
better solution.
-F hasn't being working for long. This commit adds a switch
--no-fading-openclose (and a configuration file option of the same name)
to simulate the behavior when only -F is enabled, which disables fading
when opening/closing windows, and makes -F an alias for -f.
Attempt to fix the transparency issue of Firefox and Chromium location
bar dropdown window by marking override_redirect windows as active. This
may not work completely and could have other side effects. Experimental.
Enable by using --mark-ovredir-focused.
- Add support of window-type-specific options (fade, shadow, and
opacity) in configuration file parsing. Syntax shown in
compton.sample.conf.
- Replace wintype_name() with an array of window type names. Code
clean-up.
- Add support for parsing configuration files using libconfig.
(Dependency on libconfig could be made optional once we get some
better building system.) Few tests has been done, bugs to be expected.
compton searches for a configuration file mostly according to the XDG
standard. Firstly the configuration file requested by --config, then
$XDG_CONFIG_HOME/compton.conf (~/.config/compton.conf, usually), then
~/.compton.conf, then compton.conf under $XDG_DATA_DIRS (often
/etc/xdg/compton.conf). A sample configuration file is supplied as
compton.sample.conf. Configuration file syntax may change in the
future. Commandline switches has higher priority than configuration
file, except for --shadow-exclude. Use --config /dev/null to
temporarily disable configuration file.
- Fix a bug that causes windows to disappear or be partially rendered on
opacity changes.
- Fix a bug that causes some windows to ignore -i (inactive_opacity) and
--inactive-dim, caused by the default window type change in
a5d9955ca4.
