LFortran

LFortran now works in WebAssembly. Here is a very alpha-version demo that runs in your browser and it is *fast*: dev.lfortran.org It still has many bugs, which you can report here if they are not already reported: github.com/lfortran/lcomp… github.com/lfortran/lfort…

LFortran is at the front page of Hacker News right now: news.ycombinator.com/item?id=471880…

We've come a long way. Now we are just compiling as many codes as we can until we can expect LFortran to just work; after that we will work on performance. Then we will announce beta quality.

LFortran can now compile the Fortran Package Manager (fpm): lfortran.org/blog/2026/02/l…. Big milestone for us!

As any respectable Fortran compiler must do, LFortran now compiles LAPACK, probably the most famous Fortran library. All tests pass, single/double precision, real/complex, 32-bit/64-bit integers. lfortran.org/blog/2026/02/l…

@cfdlab Yep, using the LFortran compiler (@lfortranorg) allows some interactivity with Jupyter but it ain't feature-complete obviously. They're making an awesome work though. As for plotting, you can find a list of tools following this link: tinyurl.com/mprs2txr

Just created a guide and test suite for setting up a C & #Fortran dev environment on Windows, covering MSVC, MinGW (MSYS2), and Intel oneAPI. Hope this helps others! Feedback welcome! @fortrantip @lfortranorg @fortranlang github.com/Foadsf/win-mul…

The BerkeleyLab/assert library now supports LFortran! github.com/BerkeleyLab/as…

LFortran compiles POT3D, a solar coronal magnetic field solver. It uses MPI and `do concurrent` and runs in parallel correctly. lfortran.org/blog/2025/03/l…

Congrats to Flang on the big milestone: blog.llvm.org/posts/2025-03-…. Thanks for mentioning LFortran and fortran-lang.org (@fortranlang) as well.

LFortran compiles Prima lfortran.org/blog/2025/03/l…

LFortran has just reached 1,000 stars on GitHub

LFortran is now in the Compiler Explorer (@CompileExplore), big thanks to @sh0ck_thi and @mattgodbolt. Please report all bugs. Here is a sample link: godbolt.org/z/M8j5P39M4

We are steadily moving towards beta quality. I am very happy with the progress. The intrinsics are very fast, no runtime overhead, see the blog post for all details.

Great work guys✨. The amount of effort put in here is fascinating.

LFortran supports all intrinsic functions. Great job by @HarshitaK1107 , Parth, @Pranavchiku and the rest of the team! lfortran.org/blog/2024/11/l…

احب اشارك الشغل اللي كنت بعمله بقالي فتره ف البروجكت الواعد ده. دلوقتي كومبيلر LFortran بقا يقدر يcompile واحده من اتقل الاكواد اللي بتعمل array maniuplation. كان في تحديات كتير واتعلمت كتير من زمايلي ف التيم ومن التيم ليدر. وان شاء الله نكبر رقعه الاكواد المدعومه اكتر.🎉🎉💪

This is a huge milestone both for LFortran as well as for me personally. When I worked at @LosAlamosNatLab, SNAP was one of the codes they asked me if we could compile. And now we can! One Fortran code after another we will eventually compile them all. Join us on this journey!

LFortran now compiles SNAP and runs it correctly, our most complicated code yet. lfortran.org/blog/2024/08/l…

LFortran now parallelizes do concurrent and OpenMP on a CPU. Thanks @Pranavchiku for leading this effort! lfortran.org/blog/2024/07/l…
