 xdg: plug memory leak; saved_action_name is already strdup:ed once 
We always strdup() saved_action_name. strdup():ing it again when
filling out the application entry leads to a memory leak:

Note, saved_action_name _is_ used in multiple places in the
application struct. This patch uses the original copy in the *first*
place, while still strdup():ing it in the rest of the places it's used.

Features

For app launching

  • Fuzzy-find applications from a list and launch them
  • Icon support
  • Remembers frequently launched applications
  • Customize which .desktop files are searched
  • Option to filter apps based on OnlyShowIn and NotShowIn
  • Startup notification support
  • Launch prefix option to customize how apps are launched
  • Display a large icon of current selection if there are only a few matches
  • Option to display executables in $PATH
  • Option to execute the input rather than return an app

  • Support for true fractional scaling
  • Wayland native

For details, see man fuzzel and man fuzzel.ini

Requirements

Runtime

  • pixman
  • wayland (client and cursor libraries)
  • xkbcommon
  • cairo (optional, required by librsvg)
  • libpng (optional)
  • librsvg (optional, for enhanced SVG icon support)
  • fcft 1

Fuzzel uses the builtin nanosvg backend to render SVG icons by default. Since nanosvg is somewhat limited, we also offer a librsvg backend for SVG icons. Note that librsvg also requires cairo.

Building

  • meson
  • ninja
  • wayland protocols
  • scdoc
  • tllist 1

Installation

To build, first, create a build directory, and switch to it:

mkdir -p bld/release && cd bld/release

Second, configure the build (if you intend to install it globally, you might also want --prefix=/usr):

meson --buildtype=release \
 -Denable-cairo=disabled|enabled|auto \
 -Dpng-backend=none|libpng \
 -Dsvg-backend=none|librsvg|nanosvg \
 ../..

-D{png,svg}-backend can be used to force-enable or force-disable a specific png and/or svg backend. Note that nanosvg is builtin (i.e. it needs to external dependencies).

-Denable-cairo can be used to force-enable or force-disable cairo support. When disabled, fuzzel will not support SVGs using the librsvg backend.

Three, build it:

ninja

You can now run it directly from the build directory:

./fuzzel

Use command line arguments to configure the look-and-feel:

./fuzzel --help

Optionally, install it:

ninja install

For more detailed configuration information, see the man pages:

man fuzzel
man fuzzel.ini

Testing

Fuzzel has some automated tests in test/. To run them, Fish shell and wtype are required. The test runner can be installed within Fish shell with:

fisher install jorgebucaran/fishtape

Once installed, the tests can be run with:

fishtape test/*.fish

License

Fuzzel is released under the MIT license.

Fuzzel uses nanosvg, released under the Zlib license.
