The command builder generates a list of backend operations needed to render a layout. The goal is two fold: 1. Help with backend interface transition. The command builder generates calls of the new interface, with it we will be able to remove the compat layer. 2. Reduce code duplication. Several places in the code need to know how windows are rendered. We need that info to compare past and current layouts to figure out the overall damage region; we need that info to figure out which part of each render command is visible in the final result, and clip out unnecessary regions; and finally we need that info to actually render. I don't want to repeat the same code three times. So instead we generate all the render steps at once as commands, then operate on those commands. Right now this function is called and the results logged, otherwise it's not used. Signed-off-by: Yuxuan Shui <yshuiv7@gmail.com> |

Build
Dependencies
Assuming you already have all the usual building tools installed (e.g. gcc, python, meson, ninja, etc.), you still need:
- libx11
- libx11-xcb
- libXext
- xproto
- xcb
- xcb-util
- xcb-damage
- xcb-dpms
- xcb-xfixes
- xcb-shape
- xcb-renderutil
- xcb-render
- xcb-randr
- xcb-composite
- xcb-image
- xcb-present
- xcb-glx
- pixman
- libdbus (optional, disable with the
-Ddbus=falsemeson configure flag) - libconfig (optional, disable with the
-Dconfig_file=falsemeson configure flag) - libGL, libEGL, libepoxy (optional, disable with the
-Dopengl=falsemeson configure flag) - libpcre2 (optional, disable with the
-Dregex=falsemeson configure flag) - libev
- uthash
On Debian based distributions (e.g. Ubuntu), the needed packages are
libconfig-dev libdbus-1-dev libegl-dev libev-dev libgl-dev libepoxy-dev libpcre2-dev libpixman-1-dev libx11-xcb-dev libxcb1-dev libxcb-composite0-dev libxcb-damage0-dev libxcb-dpms0-dev libxcb-glx0-dev libxcb-image0-dev libxcb-present-dev libxcb-randr0-dev libxcb-render0-dev libxcb-render-util0-dev libxcb-shape0-dev libxcb-util-dev libxcb-xfixes0-dev libxext-dev meson ninja-build uthash-dev
On Fedora, the needed packages are
dbus-devel gcc git libconfig-devel libdrm-devel libev-devel libX11-devel libX11-xcb libXext-devel libxcb-devel libGL-devel libEGL-devel libepoxy-devel meson pcre2-devel pixman-devel uthash-devel xcb-util-image-devel xcb-util-renderutil-devel xorg-x11-proto-devel xcb-util-devel
To build the documents, you need asciidoc
To build
$ meson setup --buildtype=release build
$ ninja -C build
Built binary can be found in build/src
If you have libraries and/or headers installed at non-default location (e.g. under /usr/local/), you might need to tell meson about them, since meson doesn't look for dependencies there by default.
You can do that by setting the CPPFLAGS and LDFLAGS environment variables when running meson. Like this:
$ LDFLAGS="-L/path/to/libraries" CPPFLAGS="-I/path/to/headers" meson setup --buildtype=release build
As an example, on FreeBSD, you might have to run meson with:
$ LDFLAGS="-L/usr/local/lib" CPPFLAGS="-I/usr/local/include" meson setup --buildtype=release build
$ ninja -C build
To install
$ ninja -C build install
Default install prefix is /usr/local, you can change it with meson configure -Dprefix=<path> build
How to Contribute
All contributions are welcome!
New features you think should be included in picom, a fix for a bug you found - please open a PR!
You can take a look at the Issues.
Contributions to the documents and wiki are also appreciated.
Even if you don't want to add anything to picom, you are still helping by compiling and running this branch, and report any issue you can find.
Become a Collaborator
Becoming a collaborator of picom requires significant time commitment. You are expected to reply to issue reports, reviewing PRs, and sometimes fix bugs or implement new feature. You won't be able to push to the main branch directly, and all you code still has to go through code review.
If this sounds good to you, feel free to contact me.
