bonk - X11 toolkit

Overview

bonk - Box's windOw maNager toolKit. Bonk is a command-line tool that provides subcommands to modify windows, adjust window properties, change window decorations, and more.

Bonk is designed with X11 in mind.

Requirements

A C compiler, CMake, and libxcb to build Bonk. Running the testing suite requires Python 3, Xephyr, xtrace, and lcov. The following will build Bonk:

cmake .
make
sudo make install

Examples

Bonk executes commands based on what is read from the command line. Here's a starter example:

bonk get-focus lower

The first command, get-focus, places the current window into the window stack. The second command, lower, moves a window to the very back of the desktop. Commands that operate on a window always default to the first window in the stack.

How about making this more interactive?

bonk pick lower get-title

The pick command prompts the user to select a window by left-clicking on it. Selection can be cancelled by using any other mouse press. Like get-focus, pick loads a window into the window stack for lower and get-title to operate on.

What about using a specific window instead?

bonk raise --window 0xdeadbeef get-title

In this case, a window id is specified by the --window argument to raise. The --window argument is accepted by all commands that operate on windows. It is important to note that specifying a window replaces all other windows in the window stack.

What about finding windows that match a certain criteria?

bonk select --class firefox

This will return all visible windows that were created by firefox. To return minimized windows, add --all to the criteria.

It's possible to narrow the search further:

bonk select --all --class firefox --title Example

This returns windows created by firefox that have 'Example' in their title. The --all option means to include windows that are currently minimized.

The above search may return windows that are of no use to the user. How about limiting the search to windows that are only in the taskbar?

bonk select --clients

Most window managers provide a list of windows that they're managing. Adding --clients to search criteria provides a way to only search within that list, to prevent turning up windows that are of no interest to the user.

Window stack

The window-arg property on a command allows the following:

• %N: N-th window (first window is %0)
• %-N: Select from the end of the stack (last window is %-1)
• %@: Select all windows.

%-1: Last argument
%@: All windows

Testing

Execute ./run-tests.sh to run all tests.
