There's a new release of Nim, the systems programming language that focuses on performance, portability and expressiveness. Nim, which was formerly called Nimrod, is statically typed and compiled.
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 optoins for garbage collection.
The work on the new release of Nim has mainly been aimed at cleaning up the standard library in preparation for v1.0, but there are some improvements aside from that. The work on the library does mean there are breaking changes in this release, including the
Away from the breaking changes, the developers say that the best improvement is a
One nice touch is the documentation generator, which can now test your examples for you. You save a code sample, generate it documentation, and the code will compile and will be embedded in the procedure’s documentation. If your examples have an error in them then you will see it, together with a stack trace if your error occurs at runtime.
There's also a new mapLiterals macro that allows you to create array and sequence literals, and a new memory manager algorithm designed to reduce memory fragmentation.
The async improvements in the I/O modules of the standard library mean there is no longer an “upcoming” and standard asyncdispatch split, the former was merged and is now the default asyncdispatch implementation. A new
The final main improvements are to the Nim package manager, Nimble. Its major new feature is the support for multiple Nimble packages in a single Git/Hg repository.
