lemonbar

Gather some system information and show it in this program, not tied to any Window Manager, terminal multiplexer, etc.

Please note that the program won't detect fans connected via Molex connectors or external fan controllers. Also I have not tested it with fan splitters either.

The program is smart enough to detect whether some of your fan blades are spinning, or the particular fan have been removed. Hold down some of your fan blades and you'll see that the program won't include this fan and its RPM, release the blades and you'll see the fan and its RPM in the statusbar. Try simulating real fan hardware failure by holding down all system fan blades and watch what the program will show you, just try not to slice your cheesy fingers open in the process.

You can extend pinky-bar with Perl/Python/Ruby/Lua/R/Assembly/Lisp/OCaml/Rust/Go/C++/Slang/Tcl scripts.

If you compile your kernel from source code make sure to include your CPU and motherboard sensors as modules and not inlined.

Just an example if you use BSD - acpi/aibs, coretemp/amdtemp.


Installation for dwm

perl set.pl "distro"
autoreconf --install --force

./configure --prefix=$HOME/.cache --with-dwm --with-colors
make
make install

Installation for py3status

perl set.pl "distro"
autoreconf --install --force

./configure --prefix=$HOME/.cache --with-py3status --with-colors
make
make install

Installation for tmux

perl set.pl "distro"
autoreconf --install --force

./configure --prefix=$HOME/.cache --with-tmux --with-colors
make
make install
# ~/.tmux.conf
set -g status-style 'bg=black'
set -g status-right '#(~/.cache/bin/pinkybar)'

Installation for xmonad (or other WM)

# copy the xbm icons
mkdir -p --mode=700 $HOME/.xmonad/icons
cp -r extra/xbm_icons/*.xbm $HOME/.xmonad/icons

perl set.pl "distro"
autoreconf --install --force

# here you can specify --with-awesomewm or --with-xmobar
./configure --prefix=$HOME/.cache --with-colors icons=$HOME/.xmonad/icons

# compile 'n install
make
make install

Copy the code from extra/scripts/xmonad.sh or exec it from xinitrc or the script used to start xmonad.


Installation for lemonbar

perl set.pl "distro"
autoreconf --install --force

./configure --prefix=$HOME/.cache --with-lemonbar --with-colors
make
make install
#!/usr/bin/env bash
while true; do
    echo -n "%{r}"
    ~/.cache/bin/pinkybar
    sleep 2
done
~/script.sh | lemonbar -p

One-liner.

while true; do echo -n "%{r}" ; ~/.cache/bin/pinkybar ; sleep 2; done | lemonbar -p

Installation in FreeBSD

FreeBSD has no other way than using the module specific convention to query sysctl and obtain data from the sensors. Maintaining a list with all the possible module names and performing expensive sysctl calls in a loop to determine that X module is loaded into your system is no-go. Be prepared to spend a minute or two to find out some system information.

Determine the motherboard sensor module name.

sysctl -a|grep 'aibs'

dev.aibs.0.volt.0: 1356 850 1600
dev.aibs.0.volt.1: 3344 2970 3630
dev.aibs.0.volt.2: 5040 4500 5500
dev.aibs.0.volt.3: 12278 10200 13800
dev.aibs.0.temp.0: 39.0C 60.0C 95.0C
dev.aibs.0.temp.1: 38.0C 45.0C 75.0C
dev.aibs.0.fan.0: 1053 600 7200
dev.aibs.0.fan.1: 1053 600 7200

Copy only 'dev.MODULE.NUMBER' (if there is any number at all) and paste it into the mobo_sensor option below.

Do the same for your CPU temperature, copy and paste the variable as is. dev.cpu.0.temperature below is provided as example.

perl set.pl "freebsd"
autoreconf --install --force

./configure --prefix=$HOME/.cache --without-alsa --with-oss mobo_sensor='dev.aibs.0' cpu_sensor='dev.cpu.0.temperature'
make
make install

Send a request to the FreeBSD mailing list and request the OpenBSD sensors API to be ported.


Installation in OpenBSD

Before proceeding, you'll have to:

# detect the newer compiler that you are about to install
sed -i 's/#AC_PROG_CC(/AC_PROG_CC(/g' configure.ac

ls /usr/local/bin/automake-*
ls /usr/local/bin/autoconf-*

# then replace the numbers below
export AUTOCONF_VERSION=2.69
export AUTOMAKE_VERSION=1.15

pkg_add gcc

# after that:
perl set.pl "openbsd"
autoreconf --install --force

./configure --prefix=$HOME/.cache --without-alsa --with-oss
make
make install

Installation for anything else

pinky-bar is no longer tied to Window Managers only. With the addition of "without colors", the output can be shown in any program, just bear in mind that the more options you've supplied the more system information will be shown.

The tmux status bar in action:

The installation steps:

perl set.pl "distro"
autoreconf --install --force

./configure --prefix=$HOME/.cache --without-colors
make
make install

By choosing this 3rd installation method it is up to you where, how to start and use the system information that's produced by pinky-bar.


GNU Build System (configure) options

Before the source code is passed to the compiler, you can enable/disable the following configure options that will increase/reduce the number of dependencies required to compile the program.

It's up to you to decide which features suit you best.

mobo_sensor=
'dev.aibs.0'
FreeBSD motherboard sensor module name to use in the sysctl calls. Read the FreeBSD installation below
cpu_sensor=
'dev.cpu.0.temperature'
FreeBSD CPU temperature module name to use in the sysctl calls. Read the FreeBSD installation below

If no options are passed, the program will be compiled with:

# --with-pci is discarded in *BSD
--with-net --with-pci --with-alsa

Affects --with-gmail. If you get error 403 unauthorized, then allow less secure apps to access your account.

Affects only FreeBSD users with laptops, --without-apm will compile the program with ACPI support to obtain the current battery life.

--without-mpd will compile the program with cmus support, the options syntax stays as is.

The PCI and sensors configure options will be discarded in *BSD.

Affects only linux users with WiFi/wireless chipsets, run lsmod|grep 802 and see whether your chipset uses cfg80211/mac80211. If that's so you can rely on libnl and enable --with-libnl configure options, otherwise your chipset probably still uses we/wext, so type --without-libnl.

Affects only linux users, --with-drivetemp pretty much locks you down to hddtemp. You can adjust extra/scripts/drive-temperature.sh and compile the program --with-smartemp, so you can switch between hddtemp and smartmontools at any time without the need recompile pinkybar with different options. --with-smartemp only cares for the existence of /tmp/pinkytemp file.

--with-weather is using this URL, register yourself there, create a new API key.

Don't just rush to register yourself, read carefully what the "Free" account limits are and take in account how often the program should call their API service. I'm not responsible if you exceeded the limits, you've been warned.

# Make sure it's working first
# curl 'http://api.openweathermap.org/data/2.5/weather?q=London,uk&units=metric&APPID=28459ae16e4b3a7e5628ff21f4907b6f'

# what to pass to configure
--with-weather api_key='28459ae16e4b3a7e5628ff21f4907b6f'

Supported Linux Distributions

Replace distro with the following bases:

  • archlinux based distros: parabola, chakra, manjaro
  • debian based distros: ubuntu, linux mint, trisquel, back track, kali linux, peppermint linux, solus, crunchbang, deepin, elementary os, and the rest *buntu based distros
  • gentoo based distros: funtoo, sabayon, calculate linux
  • slackware
  • rhel based distros: opensuse (uses rpm), fedora, fuduntu, mandriva, mandrake, viperr, mageia
  • frugalware
  • angstrom
  • voidlinux
  • crux
  • alpinelinux
  • slitaz
  • tinycorelinux
  • nixos
  • paldo
  • dragora
  • guixsd

Cannot list the *BSD flavours as "distros", so they deserve their own options:

  • freebsd
  • openbsd

Configuration File

~/.pinky is the location of the configuration file. You can specify different config location via the --conf option.

If any option depends on argument, don't put any space between the option and the argument. Only true if you are not using the --shell option.

Use one option per line. Contrary to your shell, the "parser" won't expand ~/my_script.pl to /home/User/my_script.pl.

Execute the program without supplying any command line options and it will parse the configuration file. Optionally you can use different location for the configuration file, thus if you have tmux and lemonbar configs they won't clash. Here's how to use different config pinkybar --conf ~/.config/pinky-tmux.conf

/*

* Example configuration file
* comments can start with:
*   // comment, /* comment */

Linux Mandatory Requirements

  • gcc/clang/pcc
  • g/libc
  • autoconf
  • automake
  • m4
  • gawk
  • perl
  • pkg-config
  • as from binutils

*BSD Mandatory Requirements

  • gcc/clang/pcc
  • autoconf
  • automake
  • autoconf-wrapper
  • automake-wrapper
  • autoconf-archive
  • argp-standalone
  • libtool
  • m4
  • gawk
  • perl
  • pkg-config
  • as from binutils

Some llvm and gcc versions will not check for headers and libraries in /usr/local, and you might get something like ld cannot find -largp, if that's the case for you, you should export the following environment variables:

export LDFLAGS='-L/usr/local/lib'
export CFLAGS='-I/usr/local/include'

It seems that OpenBSD 6.3 clang compiler fails to find -largp even with the above environment variables. You are advised to install gcc.

After editing the wrong prototype I managed to stumble upon a bug in OpenBSD's own libc.

Warning !!! OpenBSD users !!!

The majority of SCN* macros differs from their PRI* cousins. And I cannot guarantee the accuracy of fixed width integers when OpenBSD own libc managed to use different format specifiers. Read extra/misc/openbsd_bugs.md for more details.

Opt-in Requirements

Start linux camp:

The Internet related options rely on headers provided by iproute2. By default, the program will try to compile with those headers included. If you want to use this program without Internet related options, configure --without-net.

  • iproute2

WiFi/wireless chipsets supporting mac80211/cfg80211:

  • libnl (>= 3.0)
  • pkg-config

In Gentoo, there are two versions of pkg-config. The first one is dev-util/pkgconfig and the second one is dev-ruby/pkg-config. In order to use the first one, you'll have to export pkg-config path to the following environment variable:

export PKG_CONFIG_PATH=/usr/bin/pkg-config

You also have to edit m4/extend.m4 and edit the line PKG_CHECK_MODULES([RUBY], [ruby-2.2 >= 2.2] to point to the correct ruby version that you have installed. Finally, configure with --with-libnl.

To read drive temperature from S.M.A.R.T.:

  • The --with-drivetemp requires curl.
  • The --with-drivetemp-light does not rely on curl, and will not force -O0 CFLAGS.

    # --with-drivetemp
    0.01s user 0.00s system 72% cpu 0.008
    
    # --with-drivetemp-light
    0.00s user 0.00s system 15% cpu 0.006
    
  • The --with-smartemp requires smartmontools (not mandatory in OpenBSD, atactl does the same job.)

    Execute the following command visudo as root and append:

    # 'frost' is my computer username
    frost ALL=NOPASSWD:/usr/sbin/smartctl
    

    Copy the code from extra/scripts/drive-temperature.sh or exec it from xinitrc or the script used to start your DE/WM.

Try running hddtemp to see if it detects your drive, depending if it has temperature sensor in first place:

sudo hddtemp /dev/sda

WARNING: Drive /dev/sda doesn't appear in the database of supported drives
WARNING: But using a common value, it reports something.
WARNING: Note that the temperature shown could be wrong.
WARNING: See --help, --debug and --drivebase options.
WARNING: And don't forget you can add your drive to hddtemp.db
/dev/sda: Corsair Force GT:  23°C or °F

The message is pretty clear "don't forget to add your drive to hddtemp.db", first run the debug command to see which field is responsible to report your drive temperature, it should be in the range of 190 - 200:

sudo hddtemp --debug /dev/sda

================= hddtemp 0.3-beta15 ==================
Model: Corsair Force GT    # COPY THIS LINE

field(1)         = 0
field(5)         = 0
field(9)         = 253
field(12)        = 237
field(171)       = 0
field(172)       = 0
field(174)       = 147
field(177)       = 1
field(181)       = 0
field(182)       = 0
field(187)       = 0
field(194)       = 22    # THIS FIELD SEEMS CORRECT
field(195)       = 0
field(196)       = 0
field(201)       = 0
field(204)       = 0
field(230)       = 100
field(231)       = 0
field(233)       = 130
field(234)       = 216
field(241)       = 216
field(242)       = 151

Open up /usr/share/hddtemp/hddtemp.db and append the Model: line that you copied earlier with the correct field that reports your drive temperature.

"Corsair Force GT" 194 C "Corsair Force GT 120GB SSD"

Next run hddtemp in daemon mode so we can request the temperature back:

sudo hddtemp -d /dev/sda

Open up your browser and navigate to 127.0.0.1:7634 and you'll get instant temperature report back to you.

The "init" lock-in for those of you that cannot choose between udev or eudev puts me in position not rely on libatasmart, regardless how neat the library is. There is stripped example program in extra/misc/skdump.c if you are curious to check and test libatasmart.

End of linux camp.

To get the sound volume level:

  • alsa-utils
  • alsa-lib

Then pass --with-alsa to configure.

*BSD users can use the baked OSS instead, pass --without-alsa --with-oss to configure instead.

Output data to the terminal using the ncurses library:

  • ncurses

To get the vendor and model name of your CD-ROM/DVD-ROM/Blu-ray:

  • libcdio
  • libcddb

In linux --without-dvd will still compile the program with DVD support. Except it will be limited only to DVD support, it will try to parse the sr0 vendor and model name detected by the kernel.

The weather related options, please go back and read Don't just rush to register yourself:

  • curl
  • gzip

Warning, I'm not responsible for any lawsuit towards you, neither encourage you to pirate content that is not licensed as free and/or for fair use.

To see the currently played song name --with-mpd:

Server side:

  • mpd (can be built with soundcloud support)

Client side:

To see the currently played song name --without-mpd:

  • cmus

The "soundcloud" alternative that is supported in cmus and your mpd client will be to download .m3u/.pls files according to the radio stream station that you are interested to listen.

The FreeBSD users will notice that "mpd" is named "musicpd".

If you've never used mpd before, copy the example configuration from extra/mpd according to your OS.

Keep an eye on the log file size if you are using raspberry pi (or equivalent device) that streams the music, make sure that it's deleted automatically if it exceeds some pre-defined size.


Execute Scripts

You can execute scripts of the following languages: Perl/Python/Ruby/Lua/R/Assembly/Lisp/OCaml/Rust/Go/C++/Slang/Tcl and you can also simultaneously execute all of them at same time too.

--with-python2 (==2.7) / --with-python3 (>=3.3)

Example script getloadavg.py

#!/usr/bin/env python
from os import getloadavg

                ↶ # VIF: VERY IMPORTANT FUNCTION
def uzer_func():
    return ', '.join([format(x) for x in getloadavg()])

Please do not export or set PYTHONPATH on its own line.

WM Specific Requirements

If you would like the output to be shown in your Window Manager, those are the following requirements:

For non-dwm WM:

  • dzen2
  • py3status
  • awesomewm
  • xmobar
  • lemonbar

For dwm:

  • libx11
  • xorg-server

Use --without-colors to skip the following step:

  • dwm compiled with statuscolor patch. The colors are specified in your dwm config.h

OCaml Language

Before invoking any of the installation commands you'll have to edit src/Makefail.skel:

pinkybar_SOURCES = pinky.ml \

Rust Language

The source code that you should edit is in extra/scripts/pinky.rs, but you'll have to edit src/Makefail.skel and add the following at the end:

pinkybar_LDADD = pinky.a

Go Language

The source code that you should edit is in extra/scripts/pinky.go, but you'll have to edit src/Makefail.skel and add the following at the end:

pinkybar_LDADD = pinky2.a

Assembly Language

The source code that you should edit is in extra/scripts/pinky.s, but you'll have to edit src/Makefail.skel add the following at the end:

pinkybar_SOURCES = ../extra/scripts/pinky.s \

Void Linux

# install the dependencies
xbps-install -S pkg-config libtool automake autoconf m4 make  # and gcc/llvm/clang

Packages alsa-utils, alsa-lib does not ship with asoundlib.h.
If you want to use --with-alsa, you'll have to compile the library manually:

wget ftp://ftp.alsa-project.org/pub/plugins/alsa-plugins-1.1.5.tar.bz2
bzip2 --decompress alsa-plugins-1.1.5.tar.bz2
tar -xvf alsa-plugins-1.1.5.tar
cd alsa-plugins-1.1.5
./configure --prefix=/usr
make
sudo make install

Tiny Core Linux

# install the dependencies
tce-load -wi sed.tcz pkg-config.tcz libtool.tcz grep.tcz glibc_base-dev.tcz \
gcc.tcz m4.tcz perl5.tcz gawk.tcz make.tcz autoconf.tcz automake.tcz

# run this next
libtoolize --force
aclocal
autoheader
automake --force-missing --add-missing

Wish List

It would be great if we can add NetBSD support.

History

The project began (on February 22, 2015) as simple Conky replacement written in 3 days when I switched from Openbox to dwm, here's some history:

I had 8 wonderful months with Openbox and the time to try and learn something new has come.

I was wondering these days what to do, either write some lengthy tutorial or do some new changes to my Openbox configuration files. And then a link to someone's laptop made me to change my mind.

The guy was running dwm, which in turn is dynamic window manager (hence the name). I was impressed by his desktop screenshot and decided to delay my plans and give 'dwm' a try.

The picture below represents my 3rd day with dwm.

Since it is written and configured in C, I had no trouble getting it running, patched and configured they way I want to in the very first day.

*My first day was all around to get dwm working, and deprecate Conky with my own version written in C that depends entirely on the standard library and doesn't call any 3rd party program. And that is how dwm-bar.c was born.*

*Later on saw that in the dwm website there was dwmstatus examples and borrowed the code that sets the root window name (the colored ram, drive, kernel, volume and time), so edited my program to output the data to the root window, instead using xsetroot in addition with my first dwm-bar.c version. I have cloned and pushed my program to their git, so by the time you read this post it will be merged.*

On the second day I wanted to add some colorization and icons to the status bar without using dzen2 or any other 3rd party program. There was enormous number of patches in the dwm website, and to be honest the colorization patch posted there was broken and incomplete. Thankfully to GitHub's searching functions I managed to find different colorization patches, I have tried the ones with pango and cairo, but my system gpu is too weak to handle all the different effects.

I don't have to mention that almost every patch I came across in Internet was broken or incomplete, and it was up to me to fix it.

On third day (today) my primary task was to add only colorization and I did it. Here is a link to my dwm fork and patches dwm-fork
