IronScheme VS F#

Yep, they are a foreign idea in pretty much all languages, but they are super easy once you figure them out.

If anyone actually wants to get their hands dirty to learn about Lisp macros, I recommend picking a Lisp implementation like SBCL, GNU Guile, Emacs, Clojure, or Hylang depending on what kind of environment you're comfortable with. The key about each of the Lisp implementations I mentioned here is that they all support "Common Lisp style macros", which are the bare bones most obvious way to do macros in Lisp.

Then I recommend using your choice of Lisp to implement a language feature you use in another language. It doesn't matter if that language feature already exists in your choice of Lisp, you can still implement it yourself. For example, you can choose to implement C-style for loops or while loops, asynchronous coroutines like Go, pattern matching, lambdas, whatever. I actually implemented asnyc/await in IronScheme and pushed it upstream[0].

If you want to read more about Lisp macros, I have really enjoyed the book Let over Lambda. I have also heard a lot about On Lisp by pg, but I haven't read that myself yet. Also if you really want to dive off the deep end into the beauty of programming, I recommend SICP.

I recently pushed a library to IronScheme to implement anyc / await in a way that I felt was reasonable. Before that, IronScheme had pretty limited support for concurrency, so my goal was to create a library that provided concurrency facilities in a way that would interop nicely with .NET libraries.

Apparently this costs $99/yr for a company called Apex Data Solutions to wire the freely available IronScheme into Office 365 via its extension model. See their marketing and shop pages.

I love this example: https://github.com/IronScheme/IronScheme/commit/2f847793946935bd9143cdfb064f9006f763df68

you mean IronRust, to go with IronRuby and IronPython, IronScheme, and IronJS

F# F*

This year I've been attempting Advent of Code in my favourite programming language, F#. This is a beginner(ish) centered post about making incremental changes from the smallest possible solution to something more robust.

I can recommend polyglot notebooks in vs code, so you can mix different languages.Take a look athttps://fsharp.org/ for some project ideas and frameworks.

I have many less followers on Mastodon than in the Birdsite (40 vs 341), yet my activity has generated many more interactions than there. Not only that, among the users who decided to interact with me I counted: a co-discoverer of the Laniakea supercluster, one of the lead developers behind F#, the author of many important books on Java & JVM, plus many others. I'm literally a nobody, but this time there was no algorithm relying on relevance and engament metrics to decide what to present to each one of us.

FP devs differ based on language here. Elm, like F#, tends to encourage "a bunch of functions and types in a file". While Elm supports modules, we don't really care where it came from; they're all pure, all deterministic, the compiler tells us if it works.

The builtin fsharp collections actually are just "immutable", not persistent as you mention. (Ref: https://github.com/fsharp/fsharp/blob/master/src/fsharp/FSharp.Core/map.fs. This is just an AVL tree that returns a copy on mutations: https://github.com/fsharp/fsharp/blob/577d06b9ec7192a6adafefd09ade0ed10b13897d/src/fsharp/FSharp.Core/map.fs#L118)

You can dive into .NET ecosystem by trying F#. It's functional-first language so this should be familiar.

ReScript code is just like F# or OCAML; it doesn’t have a function parse phase like JavaScript, so we have to define our functions and types first before we can use them. That’s fine, but makes explaining the code backwards (meaning you start at the bottom of the file and work your way up), so we’ll start at our lambda handler and explain each part, regardless of where it’s defined.

F# is a JavaScript and .NET language for web, cloud, data-science, apps and more.

Also a programming joke
