Let's collect relatively new research programming languages in this thread

• koka

  31 3,036 9.8 Haskell

  Koka language compiler and interpreter

  

Koka, already cited in this thread, early 2010s. Koka's first claim to fame was a usable effect system (at the type were, basically, effect systems were not usable in practice; in fact few languages have managed to do as well as Koka since). Now its author is working on cool implementation strategies for functional languages as well.

• HVM

  107 7,052 6.7 Rust

  A massively parallel, optimal functional runtime in Rust

  

Sure. Sorry I should have linked this before, but I was on mobile. Here you go: https://github.com/Kindelia/HVM/issues/44

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• hylo

  54 1,101 9.9 Swift

  The Hylo programming language

  

I’m a big fan of Val. The value semantics model of Swift is really amazing when you use it, and Val just focuses only on this model. It’s like a cross between functional and imperative programming, and feels great.

• koika

  2 126 0.0 Coq

  A core language for rule-based hardware design 🦑

  

https://github.com/koka-lang/koka Algebraic effects and reference counting. https://github.com/mit-plv/koika hardware description DSL for coq

• Vale

  64 1,660 6.8 Scala

  Compiler for the Vale programming language - http://vale.dev/ (by ValeLang)

  

We're working on adding a more user-friendly borrow checker in Vale (https://vale.dev), ehich I'm pretty excited about. Here's a draft/preview about it I aim to post later today or tomorrow: https://verdagon.dev/blog/zero-cost-memory-safety-regions-overview

• jasmin

  1 221 9.4 Coq

  Language for high-assurance and high-speed cryptography (by jasmin-lang)

  

Jasmin, late 2010s, a language designed to be lower-level than C and provide good low-level control for cryptographic code. Basically a new take on "C as a high-level assembly language", with formal semantics etc. I suspect that this design space is rather close to "a good language to use as a compiler backend", but I think this would require changes to Jasmin and no one is working on that as far as I know.

• cogent

  4 157 0.0 Isabelle

  Cogent Project

  

Cogent, late 2010s, a language with linear types for verification. The idea is that you write functional-looking code that is easy to verify using the functional semantics, but with an efficient compilation strategy enabled by linear types to get realistic system programs.

• InfluxDB

  www.influxdata.com sponsored

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

• futhark

  52 2,283 9.8 Haskell

  :boom::computer::boom: A data-parallel functional programming language

  

https://futhark-lang.org/ High-performance purely functional data-parallel array programming

• effekt

  13 281 9.6 Scala

  A research language with effect handlers and lightweight effect polymorphism

• karamel

  1 380 9.4 OCaml

  KaRaMeL is a tool for extracting low-level F* programs to readable C code

  

Jasmin and F* don't have similar goals, Jasmin is a language designed to precisely express low-level code, while F* is a generalist language for verified programming. There is a subsystem of F* that performs extraction to "readable C code", Karamel (used to be called Kremlin), but you get the usual limitations of C code as a high-level assembler, and also an embedded assembly layer built on Vale. Project Everest therefore generates artifacts that are a mix of C and assembly, rather than a new low-level language design as Jasmin.

• hacl-star

  8 1,578 9.6 F*

  HACL*, a formally verified cryptographic library written in F*

• usuba

  1 54 0.0 C

  A programming language to write bitsliced ciphers

  

Usuba, a domain-specific language for writing efficient "bit-sliced" cryptographic code. (Jasmin is a low-level language for fine-grained performance control, which was motivated by the needs of cryptographic routines, but its design is not crypto-specific. Usuba is a domain-specific language for cryptography.)

• datafun

  3 375 10.0 TeX

  Research on integrating datalog & lambda calculus via monotonicity types

Datafun, a take on a "higher-order" (functional) extension of Datalog.

• ponyc

  61 5,594 9.3 C

  Pony is an open-source, actor-model, capabilities-secure, high performance programming language

  

Surprised you didn't mention Pony :)

• cubicaltt

  3 556 2.3 Haskell

  Experimental implementation of Cubical Type Theory

- cubicialtt a programming language based on cubical type theory in which univalence from homotopy type theory isn't an axiom but a theorem
