css··on Superlogical
I like the concept. I maintain something similar [0], a daemon-backed supervisor where each task is one command in its own PTY (builds, servers, agent sessions), rather than a persistent shell workspace.

What's wrong with `imessage-exporter`?

css··on Getting syntax highlighting wrong
I love the concept of lexical differential highlighting [0] (discussed here [1]). It makes reading math so much easier, especially in dense code. However I don't know of any editor that implements a feature like this.

If you paste the following code into the example block in [0] you can see how useful this can be:

    while (b - a).abs() > EPSILON {
        let c = a + (a - b) * f_a / (f_b - f_a);
        let f_c = J(c);
        if f_c * f_b == 0.0 {
            a = b;
            f_a = f_b;
        } else {
            f_a /= 2.0;
        }
        b = c;
        f_b = f_c;
    }

css··on Too Many Open Files
I ran into this issue recently [0]. Apparently the integrated VSCode terminal sets its own (very high) cap by default, but other shells don't, so all of my testing in the VSCode shell "hid" the bug that other shells exposed.

css··on Reverse Engineering Apple's typedstream Format
Semi-related, one of the `imessage-exporter` contributors provided a great write-up on reverse engineering the handwritten and digital touch message protobufs [0]. The reconstructed proto files are [1] [2].

css··on Reverse Engineering Apple's typedstream Format
The plist is probably a binary plist (header bytes `bplist00`) generated by NSKeyedArchiver, and then the specific data you need is encoded inside. Edited iMessages are stored in the exact same way. Luckily the plist itself is not that complex–but typedstream is pesky to work with.
css··on Reverse Engineering Apple's typedstream Format
iMessage uses a very strange amalgamation of typedstream (message content), keyed archives (app messages, sticker data), and protobufs (Digital Touch, handwriting) for different features. I wonder what motivated all of those design decisions.
css··on Reverse Engineering Apple's typedstream Format
Apple provides Messages for Business [0], but if you have a machine that can read the iMessages as they come in, you could use the library [1] that powers `imessage-exporter` as a bridge.

css··on Show HN: iMessage-exporter: a comprehensive CLI app and library
The California Poppy release [0] of `imessage-exporter` is the biggest update yet. Most notably, it implements a novel `typedstream` deserializer [1], allowing it to understand the data stored in `NSAttributedString` binary data that is stored in the iMessage database.

I've spent a long time reverse engineering nearly every aspect of Apple's iMessage SQLite tables to build this program. As far as I know, there are no other tools that support the full corpus of iMessage features [2], including edited messages, app messages, reactions, text range formatting, and threads.

Hey, this sounds like an interesting problem. I am always looking for edge cases to test, if you have time would you mind checking if https://github.com/ReagentX/imessage-exporter works for you and if it crashes in that spot?

Maybe cartel is a strong word, but there are many states in the US where, in order to operate a medical facility or provide a service, you must get permission from all of the existing facilities in the locality: https://en.wikipedia.org/wiki/Certificate_of_need

This extends to even purchasing medical equipment.

If you are talking about data missing from the `text` column, for some reason it disappears after you read a message. The content is stored in a binary blob in a different column, which I parse like this: https://github.com/ReagentX/imessage-exporter/blob/c73bc4d66...
