# Auto_news

A utility to fetch article requests from slack and generate pdfs for them, fully automatically.


## Running - Pure docker
> I recommend running with docker compose instead
### How to run - auto archiving mode
In this mode the program is launched as a docker container, in a headless mode. For persistence purposes a local storage volume is required, but that's it!

`docker run -it -v <your storage>:/app/file_storage/ auto_news`

You can specify additional parameters: 

`docker run -it -v <your storage>:/app/file_storage/ auto_news debug` runs with debug values (does not write to prod db, does not send mails)

`docker run -it -v <your storage>:/app/file_storage/ auto_news upload` catches up on incomplete uploads to archive.

`docker run -it -v <your storage>:/app/file_storage/ auto_news reducedfetch` makes assumption about the status of the slack chat and greatly reduces the number of api calls (faster start up).

These parameters can be combined (mostyl for testing I guess)

Finally for manual file verification:

`docker run -it -v <your storage>:/app/file_storage/ -e DISPLAY=":0" --network host -v \$XAUTHORITY:/root/.Xauthority auto_news check` lets you visually verify the downloaded files. The additional parameters are required in order to open guis on the host.


### How to run - development mode
In this mode, a docker container is launched with an additional volume, the local code. You can test your code without the need to rebuild the image.

`docker run -it -v <your storage>:/app/file_storage/ -v <your code>:/code/ --entry-point /bin/bash auto_news`
You are droppped into a bash shell, in which you can navigate to the `/code` directory and then test live.

### Cheat-sheet Remy:

`docker run -it -v /mnt/Data/COSS/Downloads/auto_news.container/:/app/file_storage/ auto_news`

`docker run -it -v /mnt/Data/COSS/Downloads/auto_news.container/:/app/file_storage/ -v /mnt/Data/COSS/Development/auto_news/app:/code --entrypoint /bin/bash auto_news`


`docker run -it -v /mnt/Data/COSS/Downloads/auto_news.container/:/app/file_storage/ -e DISPLAY=":0" --network host -v XAUTHORITY:/root/.Xauthority auto_news check`


## Running - Docker compose 

I also wrote a rudimentary docker compose file which makes running much more simple. Just run

`docker compose --env-file <desired mode> up`

All relevant passthroughs and mounts are specified through the env-file, for which I configured 4 versions: production, debug (development in general), upload and check. These files will have to be adapted to your individual setup but can be reused more easily.

For the debug env-file, you will likely want interactivity, so you need to run:

`docker compose --env-file env/debug run auto_news`

<!-- > Note:
>
> The `debug` requires additional input. Once `docker compose up` is running, in a new session run `docker compose --env-file env/debug exec bash`. The live-mounted code is then under `/code`. Note that the `DEBUG=true` environment variable is still set. If you want to test things on production, run `export DEBUG=false`.

## Building

> The software (firefox, selenium, python) changes frequently. For non-breaking changes it is useful to regularly clean build the docker image! This is also crucial to update the code itself.

In docker, simply run:

`docker build -t auto_news --no-cache .`

where the `Dockerfile` has to be in the working directory

In docker compose, run the usual command, but append 

`docker compose ... up --build`






## Roadmap:

[ ] automatically upload files to NAS

[ ] handle paywalled sites like faz, spiegel, .. through their dedicated edu-friendly sites
