bemenu
======
Dynamic menu library and client program inspired by dmenu
![preview](.github/preview.svg)
## Releases
Releases are signed with [29317348D687B86B](http://pgp.mit.edu/pks/lookup?op=vindex&search=0x29317348D687B86B) and published [on GitHub](https://github.com/Cloudef/bemenu/releases).
## Building
```sh
# Build everything
make
# To build only certain features, pass the targets which you are interested into
#
# You can also use the following meta-targets for common features:
# - clients (bemenu, bemenu-run)
# - x11
# - wayland
# - curses
#
# For example this would build the bemenu and bemenu-run binaries and the x11 backend:
make clients x11
# To install the built features, simply run:
make install
# NOTE: You may get errors during install when not building all the features.
# These errors are free to ignore if `Install OK!` is printed.
# By default that will install to /usr/local, but you can change this with PREFIX
make install PREFIX=/usr
# Other usual variables are available for modifying such as DESTDIR, bindir, libdir and mandir
# Note that if you want a custom PREFIX or libdir, you should pass those during build as well,
# since they will be used compile-time to figure out where to load backends from!
# HTML API documentation (requires doxygen installed):
make doxygen
# To test from source, you have to point the LD_LIBRARY_PATH and BEMENU_RENDERERS variables:
LD_LIBRARY_PATH=. BEMENU_RENDERERS=. ./bemenu-run
```
## OSX
### Homebrew
```sh
# Make sure you have GNU Make and pkg-config installed
brew install make pkg-config
# You may need to setup your pkg-config to point to the brew version of the libraries
# For example to build curses backend, you'd do:
PKG_CONFIG_PATH="/usr/local/opt/ncurses/lib/pkgconfig" sh build-osx.sh curses
# Other than that, follow the normal build steps, but use `build-osx.sh` instead of make
```
### Nix
There is darwin.nix provided in this repo, you can install bemenu with it by running
```sh
nix-env -i -f darwin.nix
```
This installs only the curses backend.
## Dependencies
- C compiler
- scdoc to generate manpage
### Backend-specific
All dependencies below are searched with `pkg-config`
| Backend | Dependencies |
|----------|------------------------------------------------------------------------|
| curses | ncursesw |
| x11 | x11, xinerama, cairo, pango, pangocairo |
| Wayland | wayland-client, wayland-protocols, cairo, pango, pangocairo, xkbcommon |
Currently, pasting from clipboard is done at runtime with `wl-paste -t text/plain` and `xclip -t text/plain -out`, attempted in that order.
### Installing the dependencies
#### Ubuntu 20.04
```sh
sudo apt install scdoc wayland-protocols libcairo-dev libpango1.0-dev libxkbcommon-dev libwayland-dev
```
## Environment variables
| Variable | Description | Value |
|------------------|-----------------------------------------|----------------------|
| BEMENU_OPTS | Options for bemenu, bemenu-run from env | Any cli argument |
| BEMENU_BACKEND | Force backend by name | x11, wayland, curses |
| BEMENU_RENDERER | Force backend by loading a .so file | Path to the .so file |
| BEMENU_RENDERERS | Override the backend search path | Path to a directory |
| BEMENU_SCALE | Override the rendering scale factor | Float value |
## About Wayland support
Wayland is only supported by compositors that implement the [wlr-layer-shell](https://github.com/swaywm/wlr-protocols/tree/master/unstable) protocol.
Typically [wlroots](https://github.com/swaywm/wlroots)-based compositors.
