These TUI apps are available in my open kiosk ssh service, connect like this:

ssh kiosk@apps.noulin.net
yes

About the SSH app service

My TUIs run in linux terminals and are built with:

Sheepy (and libsheepy) - my build system
Modified version of termbox
A widget library (twid)
Written in C

There are no dependencies besides sheepy and gcc.

The terminal font has to support unicode 15 for the TUIs using the 2x3 pixel characters and the terminal is configured for RGB 24 bit colors, when using terminal multiplexers (screen, tmux) you might not get 24bit colors.

The TUIs built on twid have these common key shortcuts:

F1     - Help (blue box on screen top)
q      - Quit
esc    - Quit/Close help
`      - Disable/Enable mouse
ctrl+/ - Change colors (c+7, c+-, c+_)
ctrl+p - Take a screenshot (as text)

I use i3 and I have shortcuts to start my TUIs on terminal windows, I start my calendar in the st terminal with Win/Cmd Key + d:

bindsym $mod+d exec st -e calendar

After sheepy is installed, the TUIs below are installed like this:

sudo spm -g install PACKAGE_NAME

On my laptop, it takes less than 16ms to start these TUIs.

Sheepy

Sheepy is a build system for using C as a scripting language like python. It takes less than 5 minutes to install sheepy on a machine:

apt-get install gcc git
git clone https://spartatek.se/git/sheepy.git
cd sheepy
sudo -H ./install.sh

I noticed some people have issues with `git clone`.

I cant clone sheepy

An alternative is too download this tar file:

Sheepy and Libsheepy repositories (45MB)

And then run:

tar xf sheepyAndLibsheepy.tar.gz
cd sheepyAndLibsheepy/sheepy/
sudo -H ./install.sh

The readme has more details.

I reimplemented `paku paku` in C for the terminal (a font with unicode 15 is required to display correctly).
