Finally got around to some more json formatting activity!
- error messaging proof of concept via codespan diagnostics
- handle unexpected control characters
- handles whitespace as per the spec

You can also pattern match it!

Now my JSON formatter has prettification and generally configurable options!
I handled
- arbitrary nesting
- better error messaging for unterminated values
- extracted object parsing from top level state machine
I am scared to handle proper string escaping 😅

I made a quick JSON formatter tonight!
Whenever I hear about syntax trees, I feel the need to build something related
I handled primitives and objects with primitive values and shall handle some nesting soon!

The tracing crate is so beautiful. With just an instrument annotation, I can attach the video id if it exists to all the events for DB calls and HTTP requests throughout the life of my endpoint
![#[instrument(skip(pool), fields(url, video_id = ?YTUrl::try_from(url.as_str())?.id()))]
async fn summarize(
Query(SummaryParams { url }): Query<SummaryParams>,
State(pool): State<PgPool>,
) -> Result<(StatusCode, Json<Value>)> {](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:awmy6tnchsgeyg3g7gtsj5lq/bafkreiajpt3mwsyov6tg7v3c4rvr2t2p5div7fxvxupy6zckyzgp7nu3ry@jpeg)

I spent 30 minutes wondering why my records weren't being saved in the database 🙃
Hint: the syntax is all correct and the query runs fine

I missed "on" from Haskell in TypeScript and it was pretty straightforward to implement! Unfortunately both "fn" and "fn2" need passed at the same time for good inference, but I'm satisfied either way 😀
![const len = ({length}: {length: number}) => length;
const compare = <T extends number | string>(a: T, z: T) =>
a === z
? 0
: a > z
? 1
: -1;
const on = <T, U, V>(fn: (x: T, y: T) => U, fn2: (x: V) => T) => (x: V, y: V) => fn(fn2(x), fn2(y));
["hi", "slkdfjsldkfljsk", [10, 11]].sort(on(compare, len))](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:awmy6tnchsgeyg3g7gtsj5lq/bafkreihufp4fa4zhuofcz3tk2tlqxjm3jwhru3zae3a7f3kgf3xubuvmwy@jpeg)

Did a codewars in COBOL to see what all the fuss was about. I'm sure I could simplify this if I dug more into it
My review after writing an extremely simple program is that it's odd by modern standards. It's interesting to have so much control over datatypes via pictures

How do y'all feel about the chatbot integrations in firefox? On a first glance it was a little odd, but it's been very nice. Sometimes it gets confused about what page I'm on, but that's to be expected with experimental features right?

Wrote some terrible code to get multiple grammar errors working together! Now you can be notified of sticky lines. Sticky words hold sentences together but can make them tough to get through
Some examples are "so", "the", "that", "a"
I'm thinking about user configurable thresholds eventually!

Wrote an SVG by hand since I couldn't find any tools that worked well. Now I have a very nice squiggly boy under my errors!

There are real errors coming from a real server now! I started with checking if the first word on a line was capitalized
You may notice that the underline doesn't show up under the g, and that's because underlines on Firefox just do that for some reason, so text decorations aren't viable here

Decided an API to mark spans as errors and added a custom context menu! Next I'll be onto making an API to send some errors over. I'm gonna go with Haskell because why not!

Making a (hopefully) accessible text editor! I've been frustrated by text editors that refuse to let screen readers read anything or hide the errors themselves
