Diagnosing and Fixing Stack Overflow Errors in OCaml
Learn how to diagnose and resolve OCaml Stack_overflow exceptions by identifying non-tail recursive calls and implementing accumulator-based patterns to enable Tail-Call Optimization (TCO).
Enforcing Reproducible OCaml Builds with Dune Explicit Dependencies
Learn how to use Dune's explicit module and library stanzas to eliminate implicit dependencies and ensure reproducible, sandboxed OCaml builds.
Sealing OCaml Libraries and Sharing Test Code with Dune Without Bloating Your Binary
A practical guide to using Dune's wrapped libraries, .mli sealing, and inline tests to share code between executables and test suites while keeping production binaries lean.
Harnessing OCaml GADTs to Build a Type‑Safe Domain‑Specific Language
Learn how OCaml’s Generalized Algebraic Data Types let you encode type‑level invariants in a DSL, with a concrete example, trade‑offs, and a step‑by‑step guide to getting started.
Architecting Generic Data Structures with OCaml Functors
Learn how OCaml functors enable parametric modules for generic data structures like Sets and Maps. Includes a complete worked example with signatures, functor implementation, instantiation, and comparison with generic functions.
Making OCaml Library Failures Explicit with result and let* Binding Operators
Replace invisible exceptions with ('a, error) result and let* so your OCaml library signatures document failure and the compiler forces callers to handle it.
Why OCaml GADTs Matter: A Practical Guide to Type‑Safe Pattern Matching
OCaml GADTs let you encode type invariants directly in the type system, turning runtime pattern‑matching errors into compile‑time guarantees. This guide walks through the syntax, a typed expression tree example, trade‑offs, and practical adoption tips.
Decoupling Logic with OCaml Functors
Learn how OCaml Functors allow you to build reusable, type-safe components by treating modules as first-class arguments to create specialized implementations at compile-time.
