gleamGleam Erlang Interop: Type Safety at Dynamic Boundaries
Gleam provides a strong, static type system that compiles to Erlang, allowing developers to leverage the BEAM ecosystem. While Gleam ensures exhaustiveness and type safety within its own modules, interacting with existing Erlang libraries introduces dynamic boundaries where static guarantees are not natively maintained. When calling untyped Erlang functions,
Gleam Build Profiles: Transitioning from Dev to Prod for Erlang Targets
Build Profile Configuration Gleam 1.0+ utilizes dev and prod build profiles within the gleam.toml configuration. The dev profile is designed to preserve debug information and disable specific optimizations to facilitate local development and debugging. Production Optimization Constraints When switching to the prod profile, the compiler enables BEAM optimizat
