Shreddit
========

User Login deprecation
----------------------

Reddit intends to disable username-password based authentication to access its
APIs in the near future. You can specify your username and password in the
`shreddit.yml` or the `praw.ini` to make it work **FOR NOW**. But consider
looking at the [OAuth2 instructions](#oauth2-instructions) if you intend to use
this program in the future.

Description
-----------

Shreddit is a Python command line program which will take a user's post history
on the website [Reddit](http://reddit.com), and will systematically go through
the user's history deleting one post/submission at a time until only those
whitelisted remain.

**Note:** When it became known that post edits were *not* saved but post
deletions *were* saved, code was added to edit your post prior to deletion. In
fact you can actually turn off deletion all together and just have lorem ipsum
(or a message about Shreddit) but this will increase how long it takes the
script to run as it will be going over all of your messages every run!

It allows you to maintain your normal reddit account while having your history
scrubbed after a certain amount of time.

Installation ([Click here for Windows instructions](#for-windows-users))
------------------------------------------------------------------------
1. Clone the repository
2. Run `python setup.py install`. Usually this is run in the context of a
   virtualenv or with administrative permissions for system-wide installation.
   virtual environment)
3. Copy `shreddit.yml.example` to `shreddit.yml` and edit it to your liking.
	- Make sure you specify your credentials in the file.
	- See the [OAuth2 instructions](#oauth2-instructions) if you don't want to
      use username-password based authentication.

- It's useful to have it run as an event, you can set this up as you like but I
  suggest `cron` via `crontab -e` and adding a line such as
  `@hourly cd $HOME/Shreddit && source bin/activate && shreddit` See below for
  more.
- Adding your password to the praw.ini and adding the additional output line
  can provide extra debugging help.

Cron examples
-------------

- Run `crontab -e` to edit your cron file. If you have access to something like
  vixie-cron then each user can have their own personal cron job!

- Run every hour on the hour
	`0 * * * * shreddit -c <full path to shreddit.yml>`

- Run at 3am every morning
	`0 3 * * * shreddit -c <full path to shreddit.yml>`

- Run once a month on the 1st of the month
	`0 0 1 * * shreddit -c <full path to shreddit.yml>`

If virtualenv was used, be sure to add
`source /full/path/to/venv/bin/activate &&`
before the command. For example:

`0 * * * * source /full/path/to/venv/bin/activate &&
shreddit -c <full path to shreddit.yml>`

3. Open command prompt to the folder with the zip file (Shreddit-master.zip),
   and type `pip install -U Shreddit-master.zip`
4. Open `shreddit.yml.example` in the zip edit it to your liking, and rename the
   file to `shreddit.yml`.

Caveats
-------

- Certain limitations in the Reddit API and the PRAW library make it difficult
  to delete more than 1,000 comments. While deleting >1000 comments is planned,
  it is necessary right now to rerun the program until they are all deleted.

- We are relying on Reddit admin words that they do not store edits, deleted
  posts are still stored in the database they are merely inaccessible to the
  public.
