LFortran compiles 85% Fortran stdlib We are happy to announce that LFortran can compile all numerical modules in stdlib. The stdlib library has 32 modules, here are the details of the current status:
all 32 modules compile to ASR 27 modules (85%) compile to LLVM; there are 4 hash modules (hash_32bit, hash_64bit, hashmaps, hashmap_wrappers, stringlist_type) and one stringlist_type module that does not compile to LLVM yet 24 modules pass all their tests; 3 modules (sorting, bitsets, stats) do not pass all tests yet, but simple examples that use the modules work This is sixth third-party production-grade code that LFortran can compile after SciPy.

LFortran Compiles 60% of SciPy With successful compilation of dftatom in October 2023, embarking to the new year with a remarkable stride, we are delighted to announce that LFortran can now successfully compile 9 out of the 15 Fortran packages within the SciPy library without requiring any modifications.
This is the fifth third-party production-grade code that LFortran can compile. The progress bar towards beta has thus reached 5/10.
LFortran can now compile and pass tests written for scipy.

After compiling fastGPT in September 2023, today we are happy to announce that LFortran can compile and run dftatom without any modifications, and dftatom’s continuous integration (CI) now tests every commit with LFortran, along side GFortran.
This is the fourth full third-party production-grade code that LFortran can compile. The progress bar towards beta has thus reached 4/10.
It can compile the main application in Debug mode twice faster than GFortran. In Release mode the runtime performance is within a factor of 2x slower than GFortran’s Release mode (all optimizations on).

In our last blog post from May 2023, we announced that LFortran can compile legacy and modern Minpack. Today, we are happy to announce that LFortran can compile and run fastGPT.
This is the third code that LFortran can compile. The progress bar toward beta has progressed to 3/10.
LFortran is still alpha, meaning that users expect frequent bugs and breaking changes. Alpha users are enthusiastic partners in the effort to reach beta and they dilligently report issues.

Two days ago on April 30, 2023 was the 4th anniversary of LFortran’s initial release. Our initial prototype in 2019 was in Python. Since then we have rewritten to C++ for speed and robustness. In 2021 we announced an MVP.
In this update, we are happy to announce that LFortran can compile and run both legacy and modern Minpack. We’ll start off by taking a look at the current compilation status and benchmarks of minpack.

We recently open sourced LFortran, an interactive Fortran compiler built on top of LLVM that we have been developing for the last 1.5 years. It is a work in progress and at the link you can find what works already, what is planned and a roadmap.
Here is our motivation.
Why are almost no new scientific or engineering software projects started in Fortran? Usually (in our neck of the woods) C++ is chosen instead.
