did anyone else play a ton of blobby volley as a kid? So it turns out the source is GPL 😁 been adding a ton of fun stuff to it (after porting to rust, ofc)

New post! "Automate typescript refactors with dosido" I made a tool to move files and definitions around, and for extracting folders into new monorepo packages. jaredforsyth.com/posts/dosido...

Automate typescript refactors with dosido
July 13, 2026

I don’t know about you, but my personal projects often metastasize. I start going in one direction, and after a while I’ve learned a lot about what I really want so I start a fresh implementation in a new subfolder, and along the way I’m building tools and libraries as I discover I need them. After a while it’s a tangled mess, where the production app uses maybe 30% of the code, and there are at least three reusable libraries waiting to be born, if only I could get my act together to do the cleanup.

So now I’ve finally gathered the will to do some refactoring, but why do the work by hand when I can automate the process?

I came across plim (github.com/darylcecile/...) and couldn't resist integrating it with my new block-rich-text CRDT 😄 very helpful in fleshing out my own API surface

Jared Forsyth @jaredforsyth.com · 09/06/2026

ok I think I've really got this working. - rich text CRDT (peritext-based) - movable blocks with split & join, retaining provenance and collaborative editing - strong cycle prevention both for split/join and block nesting annnd just for fun I've also implemented multicursor in the demo (cmd+click)

Here's another flex 💪 we can have a function of two arguments where *at least one* of the arguments needs to have a given attribute defined.

010

Jared Forsyth @jaredforsyth.com · 25/04/2025

ok this is just really cool. the constraints system I set up gives you "optional record arguments" for free! it would be simple to add syntax affordances for it as well, e.g. ({one, two, three = true}) => ...

020

Jared Forsyth @jaredforsyth.com · 24/04/2025

Ok so it's possible I'm overlooking something crucial, but I think I might have gotten polymorphic records to work?? without needing a distinction between (extend) and (override), as well as allowing for multiple-extend, e.g. {...a, ...b, c: 2} I haven't seen papers that can pull this off 😳

Are there any languages that allow you to "re-enter" the switch control flow, if you determine that the branch you're on isn't right? I sometimes find myself having e.g. nested switches, and I want to be able to "jump out" to the parent switch and keep going, often in a default case. same with "if"s

a code snippet illustrating two cases; a nested if block where the inner if "continues" out to the parent else, and an if nested in a switch that "continues" back out to the switch.

imagine, conway's game of life, but, hexagons (the rules are the same, cells still have 9 neighbors, every other row is just shifted over a bit. it's a display-only change)

was feeling a little braindead the 3rd day of POPL so I made a colorific game of life inspired by @todepond.com's huegene (www.todepond.com/lab/cells/dr...)

finally implemented decimal-point handling, so 2.3 doesn't get parsed as attribute access 😅

considering switching from in-place "placeholders" to tooltips that only show when your cursor is over the blank node. Thoughts?

hey I heard you like xml in your codes

Jared Forsyth @jaredforsyth.com · 07/12/2024

tables! these are a critical feature of my CST; they account for any syntax form that has children that need to be "paired"; such as records, switch statements, and more! Because you can have more than 2 columns, it unlocks features you couldn't reasonably have in a text-based syntax.

Jared Forsyth @jaredforsyth.com · 06/12/2024

placeholders! (generated for free from the parser definition) the syntax becomes somewhat self-documenting, which seems quite nice!
