Gleam is a type-safe and scalable language for the Erlang virtual machine and JavaScript runtimes. Today Gleam v1.9.0 has been published. Let's take a look! Echo debug printing There are debuggers you can use with Gleam, however the most popular ways to understand the runtime behaviour of a Gleam program is through writing tests and through print debugging. The standard library function io.debug i

Gleam is a type safe and scalable language for the Erlang virtual machine and JavaScript runtimes. Today Gleam v1.2.0 has been published, a release that focuses on improving the language server and developer experience. It's a big one both in terms of size and impact, so let's take a look as what it includes. Fault tolerant compilation Gleam's compiler has traditionally halted immediately when a c

Today Gleam v1.0.0 has been released! This is the first "stable" release of the language (more on what that means later) and a big milestone for the ecosystem. It has been a long journey and I'm proud of both the technology and the community that we've built here with Gleam. Thank you so much to everyone who has taken part in any way, you've all contributed to the project getting here in meaningfu

Gleam is a type safe and scalable language for the Erlang virtual machine and JavaScript runtimes. Today Gleam's new language tour has been launched, a way to try and to learn Gleam without having to install anything on your computer. Check it out, it looks like this: The language tour guides you through the language, from the basics to the most advanced features, introducing each concept in a way

Gleam is a type safe and scalable language for the Erlang virtual machine and JavaScript runtimes. Today Gleam v0.34.0 has been published. Let's take a look at what's new! Multi-target projects Gleam can compile to one of two targets: Erlang or JavaScript. Some packages may only support one of the two targets, possibly because they make use of Erlang features that are not available in JavaScript,

Gleam is a type safe and scalable language for the Erlang virtual machine and JavaScript runtimes. Today Gleam v0.32.0 has been published, a release that focuses on getting Gleam ready for a v1.0 release by making some breaking changes before the language is declared stable. Resolving import ambiguity Here is what Gleam's import syntax looks like: import gleam/option.{Option, Some, None} pub fn gr

Gleam is a type safe and scalable language for the Erlang virtual machine and JavaScript runtimes. Today Gleam v0.26.0 has been released, let's take a look at what's new. Incremental compilation A Gleam project is made of packages, typically a top level package and several dependency packages fetched by the package manager, and each package contains a collection of modules of Gleam code. In the ve

Gleam is a type safe and scalable language for the Erlang virtual machine and JavaScript runtimes. Today Gleam v0.25.0 has been released, featuring a long-awaited new feature: use expressions. The motivation Two of Gleam's main goals are to be easy to learn and easy to work with. In aid of these goals Gleam the language is designed to be as small and consistent as possible, drawing inspiration fro

Hot on the heels of Gleam v0.13 comes another release, Gleam v0.14! As always, let's take a look at some of the highlights. Dialyzer & Erlang typespecs Many dynamically typed BEAM languages support Erlang's typespecs, type annotations that can be analysed with the Dialyzer tool. While not as powerful or reliable as Gleam's type system it can be a useful tool for finding problems with your Erlang o

Gleam is a friendly language for building type-safe systems that scale! The power of a type system, the expressiveness of functional programming, and the reliability of the highly concurrent, fault tolerant Erlang runtime, with a familiar and modern syntax. Reliable and scalableRunning on the battle-tested Erlang virtual machine that powers planet-scale systems such as WhatsApp and Ericsson, Gleam
