Reddit (supposedly) only indexes the last 1000 items per query, so there are lots of comments that I don't have access to using the official reddit API (I run [`rexport`](https://github.com/karlicoss/rexport/) periodically to pick up any new data.)

This downloads all the comments that pushshift has, which is typically more than the 1000 query limit. This is only really meant to be used once per account, to access old data that I don't have access to.

For more context see the comments [here](https://github.com/karlicoss/rexport/#api-limitations).

Reddit has recently added a [data request](https://www.reddit.com/settings/data-request) which may let you get comments going further back, but pushshifts JSON response contains a bit more info than what the GDPR request does

Complies to the rate limit [described here](https://github.com/dmarx/psaw#features)

pushshift doesn't require authentication, if you want to preview what this looks like, just go to <https://api.pushshift.io/reddit/comment/search?author=>

#### Usage in HPI

This has been merged into [karlicoss/HPI](https://github.com/karlicoss/HPI), which combines the periodic results of `rexport` (to pick up new comments), with any from the past using this, which looks like [this](https://github.com/karlicoss/HPI/tree/master/my/reddit); my config looking like:

```reddit
class reddit:
    class rexport:
        export_path: Paths = "~/data/rexport/*.json"
    class pushshift:
        export_path: Paths = "~/data/pushshift/*.json"
```

Then importing from `my.reddit.all` combines the data from both of them:

```
>>> from my.reddit.rexport import comments as rcomments
>>> from my.reddit.pushshift import comments as pcomments
>>> from my.reddit.all import comments
>>> from more_itertools import ilen
>>> ilen(rcomments())
1020
>>> ilen(pcomments())
4891
>>> ilen(comments())
4914
```
