Mastodon markdown archive

Fetch a Mastodon account's posts and save them as markdown files. Post content is converted to markdown, images are downloaded and inlined, and replies are threaded. A post whose visibility is not public is skipped, and the post's id is used as the filename.

Implements most of the parameters in Mastodon's public API to get an account's statuses.

If a post has images, the post is created as a Hugo page bundle and images are downloaded in the corresponding post directory.

I use this tool to create an archive of my Mastodon posts, which I then syndicate to my own site following PESOS.

Example

Here is how I use this to archive posts from my Mastodon account. I exclude replies to others, and reblogs.

I use this tool programatically, and I certainly do not want to recreate the archive from scratch each time.

I first use this to generate an archive up to a certain point in time. Then, I use it to archive posts made since the last archived post.

Mastodo imposts an upper limit of 40 posts in their API. With --persist-first and --persist-last I can save cursors of the upper and lower bound of posts that were fetched. I can then use Mastodon's max-id, min-id, and since-id parameters to get the posts that I need, depending on each cae.

Generating an entire archive

mastodon-markdown-archive \
--user=https://social.coop/@ggpsv \
--dist=./posts \
--exclude-replies \
--exclude-reblogs \
--persist-last=./last \
--max-id=$(test -f ./last && cat ./last || echo "")

Calling this for the first time will fetch the most recent 40 posts. With --persist-last, the 40th post's id will be saved at ./last.

Calling this command iteratively will fetch the account's posts in reverse chronological time, 40 posts at a time. If my account had 160 posts, I'd need to call this command 4 times to create the archive.

Getting the latest posts

Calling this for the first time will fetch the most recent 40 posts. With --persist-first, the most recent post's id will be saved at ./first.

Calling this command iteratively will only fetch posts that have been made since the last retrieved post.

mastodon-markdown-archive \
--user=https://social.coop/@ggpsv \
--dist=./posts \
--exclude-replies \
--exclude-reblogs \
--persist-first=./first \
--since-id=$(test -f ./first && cat ./first || echo "")

Template

By default, this tool uses the post.tmp template to create the markdown file. A different template can be used by passing its path to --template.
