It is said that good things come to those who wait. Jacques-Henri Jourdan demonstrated Statistically profiling memory in OCaml at the 2016 OCaml Workshop and experimental branches of it existed for OCaml 4.03–4.07 in opam. Parts of the work were merged in OCaml 4.10 and the final sections landed with 4.11. The compiler provides support in the form of a series of hooks in various parts of the runtime’s allocation and garbage collection routines. A few weeks ago, Jane Street released memtrace and Memtrace viewer and earlier this week blogged about its use. I thought I’d quickly share the experience of using it on native Windows.

Memory issues can be hard to track down. A function that onlyallocates a few small objects can cause a space leak if it’s calledoften enough and those object...

This blog post and the previous one about functor packs covers two RFCs currently developed by OCamlPro and Jane Street. We previously introduced functor packs, a new feature adding the possiblity to compile packs as functors, allowing the user to implement functors as multiple source files or even ...

OCamlPro has a long history of dedicated efforts to support the development of the OCaml compiler, through sponsorship or direct contributions from Flambda Team. An important one is the Flambda intermediate representation designed for optimizations, and in the future its next iteration Flambda 2. Th...

At Tarides, we build many tools and writing UI is usually a tedious task. In this post we will see how to write functional UIs in OCaml…
