# install-cadius-action
A Github Action for installing Cadius and allowing you to manipulate ProDOS disk images in your workflows.
# Example usage
```
# This will install Cadius on your Github Runner machine
- name: Install Cadius
uses: digarok/install-cadius-action@master
with:
include_prodos: true
# Now you can use it to create a new bootable ProDOS disk
- name: Create Boot Volume
- run: |
cadius createvolume exampledsk.po exampledsk 140KB
cadius addfile exampledsk.po /exampledsk/ ./PRODOS.2.4.2/PRODOS
```
# Arguments/Inputs
This action has one input: `include_prodos`. It defaults to true, it will download the latest release of ProDOS (2.4.2) and extract all of the files to a directory called `PRODOS.2.4.2`. This allows you to use those files, if needed, in subsequent steps. So you can create a bootable disk or even add `BASIC.SYSTEM` to launch into AppleSoft BASIC. If you don't need any of the ProDOS files, you can skip this by setting it to false and save a second or two.
# Usage Recommendations
1. While you can call Cadius directly from [`run`](https://help.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idstepsrun) commands as shown above, it makes sense to put your packaging command(s) in a script which can be run locally with the same results.
2. Cadius uses a specific file, `_FileInformation.txt` for inferring ProDOS filetype and access information. That is not covered here, see the [Cadius Documentation](http://brutaldeluxe.fr/products/crossdevtools/cadius/).
3. This action is intended to pair really well with my [`install-merlin32-action`](https://github.com/digarok/install-merlin32-action) which let's you assembled the 65xx source code to build your object/system files that can then packaged inside a ProDOS image file using this action for immediate use in your emulator or flash drive. I use this workflow to handle build and release all via Github Actions.
# About CADIUS
Cadius is a disk image program originally by the amazing French team, Brutal Deluxe. They are not involved with this Open Source version, but I do recommend you view [their site](http://brutaldeluxe.fr/products/crossdevtools/cadius/) for more information on Cadius and their other incredible tools and releases.
