dwlb

A fast, feature-complete bar for dwl.

Dependencies

• libwayland-client
• libwayland-cursor
• pixman
• fcft

Installation

git clone https://github.com/kolunmi/dwlb
cd dwlb
make
make install

Usage

Pass dwlb as an argument to dwl's -s flag. This will populate each connected output with a bar. For example:

dwl -s 'dwlb -font "monospace:size=16"'

Ipc

If dwl is patched appropriately, dwlb is capable of communicating directly with dwl. When ipc is enabled with -ipc, dwlb does not read from stdin, and clicking tags functions as you would expect. Ipc can be disabled with -no-ipc.

Commands

Command options send instructions to existing instances of dwlb. All commands take at least one argument to specify a bar on which to operate. This may be zxdg_output_v1 name, "all" to affect all outputs, or "selected" for the current output.

Status Text

The -status and -title commands are used to write status text. The text may contain in-line commands in the following format: ^cmd(argument).

In-Line Command	Description
^fg(HEXCOLOR)	Sets foreground color to HEXCOLOR.
^bg(HEXCOLOR)	Sets background color to HEXCOLOR.
^lm(SHELLCOMMAND)	Begins or terminates left mouse button region with action SHELLCOMMAND.
^mm(SHELLCOMMAND)	Begins or terminates middle mouse button region with action SHELLCOMMAND.
^rm(SHELLCOMMAND)	Begins or terminates right mouse button region with action SHELLCOMMAND.

In this example, clicking the text highlighted in red will spawn the foot terminal.

dwlb -status all 'text ^bg(ff0000)^lm(foot)text^bg()^lm() text'

A color command with no argument reverts to the default value. ^^ represents a single ^ character. Status commands can be disabled with -no-status-commands.

Scaling

If you use scaling in Wayland, you can specify buffer_scale through config file or by passing it as an option (only integer values):

dwlb -scale 2

This will render both surface and a cursor with 2x detail. If your monitor is set to 1.25 or 1.5 scaling, setting scale to 2 will also work as compositor will downscale the buffer properly.

Other Options

Run dwlb -h for a full list of options.

Someblocks

To use someblocks, or any program that outputs to stdout, with dwlb, use this one-liner:

someblocks -p | while read -r line; do dwlb -status all "$line"; done
