# 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__ (specified with `-i`)
* 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
* titlebar transparency (and possibly border transparency) is on the way
* menu transparency (thanks to Dana)
## 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)
## License
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
* Myself
Not counting the tens of people who forked it in between.
Keith Packard's original license remains in the source.
## Building
The same dependencies and build as xcompmgr.
### Dependencies:
* libx11
* libxcomposite
* libxdamage
* libxfixes
* libxrender
* autoconf
To build, make sure you have the above dependencies:
``` bash
$ ./autogen.sh
$ make
```
The above will produce a single binary.
## Usage
``` bash
$ xcompmgr -cC -t -5 -l -5 -r 5 -o 0.5 -fF -I 0.065 -O 0.065 -D 6 -m 0.8 -i &
$ xcompmgr -cC -t -5 -l -5 -r 5 -o 0.5 -i &
```
