Julia is a high-level, high-performance dynamic programming language for numerical computing. It provides a sophisticated compiler, distributed parallel execution, numerical accuracy, and an extensive mathematical function library.


Warning: Package julia is compiled against system libraries and is therefore unsupported by the upstream. While it may be suitable for basic usage it is incompatible with external packages (e.g. MKL, LLVM, LLVMExtra, or packages that depend on these, like CUDA or Flux) which rely on Julia's bundled versions of its dependencies. Bugs reported against this binary will be closed.

Install julia-binAUR. The package provides official builds compiled against patched LLVM libs.
