Spleen

Spleen is a monospaced bitmap font available in 6 sizes:

• 5x8
• 6x12
• 8x16
• 12x24
• 16x32
• 32x64

Each size is provided in the Glyph Bitmap Distribution Format (BDF), and release tarballs contain the fonts in the following formats: PCF, PSF (for the Linux console), OTB, OTF, .dfont for macOS users, and FON for Windows users.

All font sizes contain all ISO/IEC 8859-1 characters (Basic Latin and Latin-1 Supplement Unicode block), Latin Extended-A characters, as well as Box Drawing, Block Elements, and Braille Patterns Unicode blocks, except for the 5x8 and the 6x12 versions.

Due to character size constraints, the 5x8 version only contains printable ASCII characters, the Braille Patterns Unicode block, and light Box Drawing characters. Please also note that there is no OpenType version for this size.

As of Spleen 1.8.0, there is now a 6x12 version containing the same Unicode blocks as the 5x8 version and the Latin-1 Supplement Unicode block.

As of Spleen 2.0.0, the 8x16, 16x32 and 32x64 versions have full support for Code page 437 (IBM PC).

Spleen also has support for Powerline symbols out of the box.

The font name is a reference to Baudelaire.

Clone the repository, convert the files to the Portable Compiled Format (PCF) using bdftopcf and run mkfontdir in the directory.

Alternatively, release tarballs provide PCF files for each size.

macOS

This has been tested in DOSBox and FreeDOS on real hardware.

Windows

Windows users should use the .fon or .otf files provided in the release tarballs.

Usage

*BSD and Linux

Update the font path to include Spleen:

xset +fp /usr/local/share/fonts/spleen/

Update .Xdefaults and add one of the following directives:

xterm*faceName: spleen:pixelsize=8:antialias=false
xterm*faceName: spleen:pixelsize=12:antialias=false
xterm*faceName: spleen:pixelsize=16:antialias=false
xterm*faceName: spleen:pixelsize=24:antialias=false
xterm*faceName: spleen:pixelsize=32:antialias=false
xterm*faceName: spleen:pixelsize=64:antialias=false

Launch xterm.

Ubuntu has bitmap fonts support disabled by default, instructions to enable it are available here.

Linux console

Release tarballs provide PSF files for each size, setfont can be used to load and set the desired font.

NetBSD console

NetBSD has .fnt files for each size which can be loaded using wsfontload(8).

For example, to load Spleen 16x32:

wsfontload -N spleen-16x32 -w 16 -h 32 /usr/share/wscons/fonts/spleen-16x32.fnt
wsconsctl -dw font=spleen-16x32

FreeBSD console

The FreeBSD package contains .fnt files which can be loaded using vidcontrol(1).

For example, to load Spleen 16x32:

vidcontrol -f /usr/local/share/fonts/spleen/spleen-16x32.fnt
