circle VS diesel

Sean Baxter created a front end c++ compiler by himself, using llvm for the back end and the gcc or clang stl. I think it took him a couple of years. https://www.circle-lang.org/. Before this happened I heard a couple of different people claiming that there would never be a totally new compiler as it was too much work.

The real Typescript for C++ is Circle.

https://www.circle-lang.org/

Just like Typescript to JavaScript, the syntax is an evolution of what already exists, not a completely different syntax.

Sean Baxter's Circle [1] is arguably the spiritual successor to MOP.

Context: https://github.com/seanbaxter/circle/blob/master/new-circle/...

Note that Circle is not an F/OSS compiler as someone pointed out before. This however doesn't make Circle less relevant, because it is actually a testament to show that C++ could have been much better without the claimed breakage. If Circle does provide a number of desirable features and its compiler can be built by a single person, then why shouldn't the committee do the same?

From all wannabe C++ replacements candidates, the only language that is really a TypeScript for C++, is Circle.

For whatever reason, Herb Sutter decided to ignore this language on the presentation.

https://www.circle-lang.org/

This is the only one with the syntax based on C++, incrementally changing the features via #pragma settings.

The second someone makes a successor language that seamlessly/directly interops with C++ _AND_ has the level of build/IDE tooling that C++/Rust have, I'm on board.

The closest thing right now is Sean Baxter's "Circle" compiler in "Carbon" mode IMO:

Unfortunately, Circle is closed-source and there's no LSP or other tooling to make the authoring experience nice.

I read through the whole of https://github.com/seanbaxter/circle/blob/master/new-circle/README.md and man, I'm drooling. Awesome work, kudos.

7. Diesel

Both seem nice. However, both of them rely very heavily on prepared statements. Unfortunately, using prepared statements is a no-go when you use connection poolers like pgbouncer, or in my case AWS RDS proxy. A discussion in Diesel indicates that disel is not going to provide any support for disabling prepared stements (https://github.com/diesel-rs/diesel/discussions/3575), and a discussion on sqlx hints that disabling prepared statements is possible, but I haven't found any documentation or examples for it.

In addition we are experimenting with prebuild versions of diesel-cli that can be installed directly. We have a set of prebuilt binaries here. We are interested in feedback about how the provided binaries work on your platform.

First of all thanks for making this great tool. As it happens I currently toy around with using it for diesel-cli releases. See the WIP PR here. I think diesel-cli is a good example of a tool that depends on system libraries as it needs to link native database drivers, so this new release is welcome. Defining the dependencies seems to allow easily building things on x86_64-unknown-linux-gnu and x86_64-apple-darwin. It seems to pick up everything in the right way there.

I did look at mysql initially. Then I started checking other crates. Diesel is an Object Relation Model (ORM), I'm not yet keen on taking on the complication of learning ORM, I give this crate a pass in the meantime.

I would recommend people look at diesel from Rust for how nice it could be. https://diesel.rs/ Look at the complex queries example. So much more readable and easier to understand.

Most wanted missing features in diesel

There are two problems with using Rust for web servers:

1. The only production-ready Rust web servers require writing async request handlers. Async Rust is not fun.

2. The only good Postgres client library is async: https://crates.io/crates/sqlx

I'm trying to remedy the first problem with https://crates.io/crates/servlin .

Solving the second problem will be another project. I hope someone else does it. There is https://crates.io/crates/diesel but it has the same problem as async Rust: incomprehensible compiler errors.
