Allocating Heap with Cranelift
I'm working on a small stack-based programming language. I'm currently at a stage where I'm trying to compile it using Cranelift. Altrough the Cranelift documentation is extensive, I'm lacking a broader picture on how to approach some things like heap-allocations and stack-management. The only example project I found are cranelift-jit-demo and this wonderful post.

JITting functions in Rust for runtime performance flexibility
First, it's much easier than you think, I swear. I strongly suggest that you start with the cranelift JIT toy language demo, it has everything that you need to get started.

We're working on a new WASM/Rust scripting system. Here I'm playing around with a script that changes the day/night cycle.
Fyi I've checked a few (from here; https://github.com/appcypher/awesome-wasm-langs): - assembly script complier is written is typescript/javascript and in theory could be compiled to wasm, and hence could be embedded, but it is only theory as noone has managed to complete this flow - rust-driver requires the linker and calls it as an external tool to link the rustcore to the user code. without the core lib i could not manage to create anything usable. - zig (somewhat similar to rust): on discord some experr said it cannot be embedded and he see no option/plan for it. - lua: they have lua runtime running in wasm, but no transpiller to wasm I've also checked a few other without any success and closest I coild get was the example language for cranelift (https://github.com/bytecodealliance/cranelift-jit-demo)

Rust libraries to build a compiler for my language?
JITs are somehow more tricky and differ in the a few points including: a) Codegen is much more time critical. b) JITs must know what's allready generated and what isn't. c) JITs often rely on informations only generated at runtime and must respond to that. See here for a JIT example witten with cranelift: https://github.com/bytecodealliance/cranelift-jit-demo.

What is a really cool thing you would want to write in Rust but don't have enough time, energy or bravery for?
You could also try Cranelift. The resulting code isn't as optimized as with LLVM, but it's faster and pleasant to use (and is written in Rust).

How to write a compiler or interpreter in rust
Backend IRs for code generation: - Cranelift (see https://github.com/bytecodealliance/cranelift-jit-demo as well as the messages on the Zulip chat if you get stuck)

So about the right way to write an interpreter
As for LLVM, I'm not sure if there are any tutorials but I would really advise writing a bytecode interpreter first, unless you already have some grasp of assembly. However, this repository: https://github.com/bytecodealliance/cranelift-jit-demo is really great for learning cranelift which is essentially an LLVM alternative.

Cranelift, Part 2: Compiler Efficiency, CFGs, and a Branch Peephole Optimizer
It was mainly built for wasm compilation. So no it is not married to rust. https://github.com/bytecodealliance/cranelift-jit-demo

Show HN: Sqlbind a Python library to compose raw SQL
I came across this yesterday for golang: https://sqlc.dev which is somewhat like what you want, maybe.
Not sure it allows you to parameterize table names but the basic idea is codegen from sql queries so you are working with go code (autocompletion etc).

ORMs are nice but they are the wrong abstraction
Agreed, but tools like https://sqlc.dev, which I mention in the article, are a good trade-off that allows you to have verified, testable, SQL in your code.

Go ORMs Compared
sqlc is not strictly a conventional ORM. It offers a unique approach by generating Go code from SQL queries. This allows developers to write SQL, which sqlc then converts into type-safe Go code, reducing the boilerplate significantly. It ensures that your queries are syntactically correct and type-safe. sqlc is ideal for those who prefer writing SQL and are looking for an efficient way to integrate it into a Go application.

Type-safe Data Access in Go using Prisma and sqlc
I was browsing awesome-go for ideas on how to setup my data access layer when I stumbled on sqlc. It seemed like a great option. Code generation is a strategy often used in the Go ecosystem and making my queries safe at compile time was an idea I really liked. Knex was great, but it required of me that I test thoroughly my queries at runtime and that I sanitize my query results to ensure type safety within my application.

Now, we are going to generate the code. For this purpose, we are going to use sqlc.
