## Free Learning Packt Publishing script

`packt-cli` is a Python script that allows to automatically grab and download a daily Free
Learning Packt ebook from https://www.packtpub.com/packt/offers/free-learning.
You can also use it to download already claimed ebooks from your Packt
account.

The script uses [anti-captcha.com](https://anti-captcha.com/) service to bypass
the Recaptcha captcha to function fully automatically. Anti Captcha employs
people to solve captcha tests. The service costs about $2 per thousand captcha
test, allowing you to operate for a few dollars over the years.

### Scheduled script execution setup

#### Debian

On Debian (and any Debian-based Linux distribution) you may use [cron](https://help.ubuntu.com/community/CronHowto) job to schedule script execution. To do this run `crontab -e` and add the following line to crontab file.

```
0 12 * * * path/to/virtualenv/bin/packt-cli -gd > path/to/log/file 2>&1
```

Adjust execution time and paths according to your setup. To verify if cron executes the script as expected, run
```
$ sudo grep CRON /var/log/syslog
```

#### Windows

**schtasks.exe** setup (more info: https://technet.microsoft.com/en-us/library/cc725744.aspx) :

To create the task that will be called at 12:00 everyday, run the following command in **cmd** (modify all paths according to your setup):

```
schtasks /create /sc DAILY /tn "grabEbookFromPacktTask" /tr "C:\Users\me\Desktop\GrabPacktFreeBook\grabEbookFromPacktTask.bat" /st 12:00
```

To check if the "grabEbookFromPacktTask" has been added to all scheduled tasks on your computer:

```
schtasks /query
```

To run the task manually:

```
schtasks /run /tn "grabEbookFromPacktTask"
```

To delete the task:

```
schtasks /delete /tn "grabEbookFromPacktTask"
```

If you want to log all downloads add -l switch to grabEbookFromPacktTask i.e.
```
schtasks /create /sc DAILY /tn "grabEbookFromPacktTask" /tr "C:\Users\me\Desktop\GrabPacktFreeBook\grabEbookFromPacktTask.bat -l" /st 12:00
```

If you want to additionaly make command line windows stay open after download add -p switch i.e.
```
schtasks /create /sc DAILY /tn "grabEbookFromPacktTask" /tr "C:\Users\me\Desktop\GrabPacktFreeBook\grabEbookFromPacktTask.bat -l -p" /st 12:00
```

### Google Drive API Setup

Full info about the Google Drive Python API can be found [here](https://developers.google.com/drive/v3/web/quickstart/python).

1. Turn on the Google Drive API
  - Use [this wizard](https://console.developers.google.com/flows/enableapi?apiid=drive) to create or select a project in the Google Developers Console and automatically turn on the API. Click `Continue`, then `Go to credentials`.
  - On the `Add credentials to your project page`, click the `Cancel` button.
  - At the top of the page, select the `OAuth consent screen` tab. Select an email address, enter a product name if not already set, and click the Save button.
  - Select the `Credentials` tab, click the `Create credentials` button and select `OAuth client ID`.
  - Select the application type `Other`, enter the name `GoogleDriveManager`, and click the `Create` button.
  - Click `OK` to dismiss the resulting dialog.
  - Click the file_download (`Download JSON`) button to the right of the client ID.
  - Move this file next to the config file and rename it to `client_secret.json`.

2. Create credentials folder:
  - Simply, just fire up the script with `-sgd` argument; During first launch you will see a prompt in your browser asking for permissions, click then *allow*
  ```
  packt-cli -sgd
  ```
  - Or if you're unable to launch browser locally (e.g. you're connecting through SSH without X11 forwarding) use this command once, follow instructions and give permission and later you can use normal command (without `--noauth_local_webserver`).
  ```
  packt-cli -c /path/to/config/file.cfg -sgd --noauth_local_webserver
  ```
  The command parameters number and their order is important!

3. Already done!
  - Run the same command as above to claim and upload the eBook to Google Drive.


In case of any questions feel free to ask, happy grabbing!
