Exports all accessible reddit comments for an account using pushshift

Project description

Exports all accessible reddit comments for an account using pushshift.

PyPi version Python 3.6|3.7|3.8 PRs Welcome

Install

Requires python3.6+

To install with pip, run:

pip install pushshift_comment_export

Is accessible as the script ps_comments, or by using python3 -m pushshift_comment_export.


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 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 context see the comments here. From what I've read on random reddit threads, doesn't seem reddit's GDPR process is worked out yet either, so not sure if that sending their legal team a request would work out well.

Complies to the rate limit described here

$ ps_comments <reddit_username> --to-file ./data.json

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=

(Personal HPI Usage)

I merge this with the output of the rexport NamedTuple in my.reddit. The raw property on the pushshift/rexport values have different values, but I've standardized the @property values across both the Comment Values:

<function my.reddit.comments() -> Iterator[Union[rexport.dal.Comment, pushshift_comment_export.dal.PComment]]>

In case it wasn't already clear, pushshift provides me with comment data going further back than 1000 entires, which reddits API can't do. I only run ps_comments once, but I run rexport every couple weeks to save any new comments/saves.
