A mobile app used to show ICP slides on mobile devices.
The /dist folder contains a zip file with 2 APKs:
- The icp_app itself
- Codeboard, an alternative lightweight keyboard with easier access to useful symbols for programming and a fully working backspace button. The latter is needed when reproducing the slides in Firefox, which has compatibility problems with some keyboards
The app works as a media player. In order to be used, it needs:
- The HTML slides
- The languages used in the slides
Slides can be created using the ICP editor and exporting for self-hosting.
These slides use full-offline as language by default, but it can be manually edited in the HTML file replacing it with the desired language.
Languages need to be manually built from the ICP bundle.
Once the desired languages have been built, a zip file can be found in dist/base/export_languages.zip.
When these 2 files are ready, they can be distributed to mobile devices and imported through the app.
A small example on how to experience the ICP slides on mobile is available in dist/DEMO.
In the following case, the slides request all languages in order to work.
<script src="full-offline.iife.js"></script>If we only use Javascript and C++, we can replace this with:
<script src="javascript.iife.js"></script>
<script src="cpp-offline.iife.js"></script>This allows to make the package with languages smaller.
In order to use the editors with C++, Java and Python the browser must support SharedWorkers. At the moment, no mobile browser supports them except for Firefox. It is still possible to use ICP with other browsers, but these languages won't be functional.
Additionally, C++ is quite heavy. Mobile devices with less than 2GB of RAM won't be able to run it. Other devices might need up to 1 minute to initialize the environment (initialization time before being able to compile the code).
