Is this project still maintained?

[0xdevalias]

Since the last update appears to be in 2017, and it only claims support for gsl 2.1 in the README (with the latest version seeming to be v2.6), i'm wondering if this project is still active/maintained?

The version of narray that is referenced is outdated and no longer maintained, having since been replaced by Numo::NArray

I also notice that there is a Numo::GSL project as well, which seems more active, and based on the maintained version of Numo::NArray

There appears to be some relatively recent discussion in #65

Just wanted to update this thread in 2023.

It seems the above PR got merged:

• Ruby 3 compatibility #66

But at least according to this issue, hasn't been released to rubygems yet:

• Publish a new release to rubygems #67

The 'no ruby 3' note in the commit referenced above (gentoo/gentoo@6671ec0) linked to the following issues as reference:

• Is this project still maintained? #63 (this issue)
• seems to require re-writing in places #65

These may also be of interest:

• Build failure with Clang 16 (-Wincompatible-function-pointer-types) #68
• Build fails: rb_gsl_common.h: error: unknown type name 'EXTERN' #69
• Please remove wrapping of functions deprecated in GSL 2.2.1 #41

If you're coming to rb-gsl for faster --lsi support in Jekyll, you might want to check the following for a better supported modern alternative:

• Can classifier-reborn work with Numo::NArray / Numo::GSL ? Is that a better choice than nmatrix? jekyll/classifier-reborn#192
  • Support Numo Gem for performing SVD jekyll/classifier-reborn#198

      • Support Numo Gem for performing SVD

      • https://jekyll.github.io/classifier-reborn/#dependencies

        • It is recommended to install either Numo or GSL to speed up LSI classification by at least 10x.

        • Numo is a set of Numerical Module gems for Ruby that provide a Ruby interface to LAPACK. If classifier detects that the required Numo gems are installed, it will make use of them to perform LSI faster.

          • Install LAPACKE
            • Ubuntu: apt-get install liblapacke-dev
            • macOS: brew install lapack
          • Install OpenBLAS
            • Ubuntu: apt-get install libopenblas-dev
            • macOS: brew install openblas
          • Install the Numo::NArray and Numo::Linalg gems. If you're using Bundler, add numo-narray and numo-linalg to your Gemfile. (If using Bundler on macOS, you should set the build config like bundle config set --global build.numo-linalg --with-openblas-dir=$(brew --prefix openblas) --with-lapack-lib="$(brew --prefix lapack)/lib".)
            • Ubuntu: gem install numo-narray numo-linalg
            • macOS: gem install numo-narray, gem install numo-linalg -- --with-openblas-dir=$(brew --prefix openblas) --with-lapack-lib="$(brew --prefix lapack)/lib"
