XOSD-XFT - OSD for X11

Inspired by libxosd.

xosd-xft supports:

• Use Xft/TTF fonts
• Xrandr and Xinerama extensions
• Allows you to choose a monitor in multihead setups - including active monitor
• Use osd-echo to display a Nerd Font glyph
• Use osd-cat to display a file

Installation

./configure
make
sudo make install

Quick Look

Using osd-echo

To display volume off glyph and execute amixer command:

    osd-echo -e 'amixer set Master off' :fa-volume_off:")

To list available glyph names that contain volume in them:

    osd-echo -lvolume

Using osd-showfile

To override the font used to display a file:

    osd-cat -f "SourceCodePro:size=14" /etc/passwd

The following command shows the output of uptime on the screen and updates every 5 seconds:

while true; do uptime; sleep 5; done | osd-cat --number-of-lines 1 -g 0x1l+0-0

Using the library

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>

#include <xosd-xft.h>

xosd_xft *osd;

int main(int argc, char *argv[])
{
  osd_geometry g;

  xosd_xft *osd = osd_create();
  if(osd_parse_geometry("300x300+0+0*middle/center", "center/middle", &g) == NULL) {
    fprintf(stderr, "%s\n", osd_error);
    return EXIT_FAILURE;
  }
  osd_set_geometry(osd, &g);
  osd_set_font(osd, "mono:size=16");
  osd_set_color(osd, "lightblue");
  osd_set_bgcolor(osd, "black", 100);

  char* message = "HELLO XOSD-XFT" ;
  osd_display(osd, message, strlen(message));

  usleep(1000000);
  osd_destroy(osd);
  return EXIT_SUCCESS;
