The Nim Team has announced version 1.0 of the language. Nim is a compiled statically typed language focusing on efficiency, readability and flexibility, and the developers say Version 1.0 marks the beginning of a stable base and that future versions of Nim won’t break the code you have written with the current version.
Nim is strongly typed and has first class functions. It is object oriented, but with composition preferred over inheritance. Nim compiles to C as its default, but can be used with different compiler back-ends to produce JavaScript, C++, or Objective-C.
Nim's options include a deferred reference counting garbage collector that is fast, incremental and pauseless; or a soft real-time garbage collector that lets you specify its max pause time. There are also other options for garbage collection. At the moment there are more than 1000 packages available for Nim, and the developers hope and expect more packages to be developed now Nim has reached 1.0.
In a blog post about the new release, Andreas Rumpf, the developer who first invented Nim, said that the main aim has been that Nim should be a small language with a macro system, which should be capable of extending Nim with all the features that the small core is missing. The current compiler plus the parts of the standard library it uses has roughly 140,000 lines of code, runs on many operating systems, and can also compile Nim code to C++ and JavaScript. Rumpf said:
"We want to focus on Nim's tooling, including Nimsuggest (Nim's code completion engine for diverse editors), Nimble (Nim's package manager) and Nimpretty (Nim's source code formatting tool). Personally I regard "incremental recompilation" (IC) the next big milestone for the Nim compiler. IC will further speed up Nim's already fast compile-times and cache the results of macro expansions and other constructs."
Google has added inline filtering to its AlloyDB for PostgreSQL database. Another addition is observability and management tooling for vector indexes, including a new recall evaluator and Go [ ... ]
We take a look at a repository containing a wealth of advanced Retrieval-Augmented Generation (RAG) resources that also includes RAG techniques for the latest trend of Agentic systems.
