Thank you. I ended up contacting the author who gave me permission quite quickly :)

I consider "no response" to be a negative answer by default :)

I sent a mail an hour ago to the author of the article. There is no "answer I don't like", if I'm not allowed to do it, then so be it. Please don't assume things when you don't know the person.

The problem is that the code generation tools does not let you learn the different parts. On top of that, all the documentation around just tell you to use the codegen tools and unless you go look at the API reference (or the source code di

The thing I don't like with Elixir/Phoenix is the code generators. I hate code generators with a passion. They obfuscate the inner workings of the library. Have you tried to find a tutorial which do not use the Mix task "phx.

The "let it crash" philosophy has a misleading name. It's not "don't handle errors", but it's "delegate the error handling to a component dedicated to this". With OTP, you have what we call a &qu

by linkdd 3y ago
It's missing the Erlang/Elixir pattern of returning a tuple `{:ok, T}` or `{:error, E}`, where we can then use pattern matching, or `with` expressions, etc... To be fair, it is very similar to a `Result<T, E>` type, which is

The problem with .map().collect()? is that it does not short-circuit. Consider: for item in iterable.iter() { item.foo()?; } You will exit the loop as soon as there is an error. But with .map().collect(), you iterate over the w

It's kinda the same for me, our product solved a problem that was not enough annoying to people for them to consider buying it, so we never had the product market fit, and never managed to sell a single license. The company still exist

After the translation of the source code to AST, I have walk through the AST to validate the code as much as possible. The generated Rust code should be valid Rust code that compiles with no error. I only have 2 exceptions to that rule: ---

This makes implementing the runtime (I use tokio for the concurrency model) faaaaaaar easier. I also get the borrow checker, move semantics, etc... that I would have to implement myself if I were to target LLVM IR. That question has been as

Well, the article is called "a simple Lisp", not "a fully featured Lisp". It's a demo, not a compliant implementation. You may be interested by https://github.com/brundonsmith/rust_lisp though

Author here, the article is more about how Rust and its ecosystem are nice tools for language designers rather than the beauty of Lisp. The crates listed in that article are the ones I use for my compiler: https://letlang.dev Li

"Faster than C", I saw people write C code slower than a Python equivalent. So I have to admit, I don't know what it means for a language to be fast, because it depends on the algorithm being implemented and the developer who

In the real world, there are no "good guys vs bad guys", no "white/black", it's all shades of grey, recognizing this is not "victim blaming". But let's avoid flamewars irrelevant to the discussio
