gleam-knowledge-patch

What problem does it solve?

Many language models are trained on data that stops at a fixed cutoff, leaving developers unaware of breaking changes, new syntax, or updated FFI and build tool behaviors in newer Gleam releases. This knowledge patch consolidates verified diffs and guidance for Gleam versions 1.7 through 1.15 so you can avoid outdated patterns and produce correct, modern code.

Core Features & Use Cases

• Provides concise, versioned notes on new keywords and syntax (echo, assert, let assert messages, string guards).
• Documents bit array improvements and JavaScript parity, including float shorthand, UTF encodings, and size expressions.
• Explains JavaScript FFI changes and generated APIs, @external on types, CommonJS support, and BitArray helpers.
• Covers build tool and project changes such as dev/ directory behavior, git dependencies, formatter rules, and dependency checks.
• Use case: review a Gleam codebase or an AI-generated snippet to update echo/assert usage, migrate JS externals to the new API, and fix record/const update patterns.

Quick Start

Load the gleam-knowledge-patch and ask the assistant to scan your Gleam files and suggest fixes for syntax, FFI, bit array, and build-tool changes between versions 1.7 and 1.15.
