picube

Silly piece of software for info screens, digital photo frames, etc. Current capabilities:

• Showing the current time
• Showing random images from Gelbooru

Usage

Quickstart:

To set up your build environment, make sure that you have GHC and Haste installed, then install haste-standalone twice; once using cabal (for GHC) and once using haste-cabal (for Haste). Finally, install haste-deck for Haste, again using haste-cabal.

To build, run the following:

$ make release
$ mkdir img
$ ./app -w img -d img

This will build both the binary and JS parts of the application, create a cache directory for downloaded images, and start serving your application on port 8080. Visit http://localhost:8080/app.html to access the info screen, and http://localhost:8080 to access the configuration screen.

To show images from Gelbooru, you need to create an account and provide the info screen with that account and its password. By default, the Gelbooru module will only show images tagged rating:safe. Note, however, that this does not constitute a guarantee that any images will actually be work safe by your standards.

When running this program on an actual info screen as opposed to your own computer, you may want to use different network settings. See ./app --help for more information on network configuration.

Building for ARM

Since Haste is currently not officially supported on ARM devices, if you want to run your program on such a device (for instance, a Raspberry Pi) you will need to compile the JavaScript part on another device, transfer it to the ARM device, and building the binary there.

On your non-ARM device:

$ make release-js
$ scp app.js your-arm-device:/path/to/picube/app.js

On your ARM device:

$ make finish-arm

This should give you an ARM binary which you can then run as described above.
