tazblog CLI

My blog stores its content in DNS, spread out over three types of TXT entries:

• TXT _posts.blog.tazj.in.: A sorted list of posts, serialised as a JSON list of strings (e.g. ["1486830338", "1476807384"])

• TXT _chunks.$postID.blog.tazj.in: JSON chunks containing the blog post text

• TXT _meta.$postID.blog.tazj.in: JSON blob with blog post metadata

All JSON blobs are base64-encoded.

This CLI tool helps to update those records.

Each blog post data is a series of JSON-encoded structures which follow one of these formats:

struct metadata {
    chunks: int
    title: string
    date: date
}

Where chunks describes the number of chunks following this format:

struct chunk {
    c: int
    t: string
}

Writing a blog post to DNS means taking its text and metadata, chunking it up and writing the chunks.

Reading a blog post means retrieving all data, reading the metadata and then assembling the chunks in order.
