From 865fc9087186b53cb60bbc516bff570d080b32bc Mon Sep 17 00:00:00 2001 From: Graham McIntire Date: Sun, 27 Jul 2025 11:05:24 -0500 Subject: [PATCH] Remove Gleam and convert encoding module to pure Elixir MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Convert Gleam encoding module to Elixir implementation - Remove all Gleam dependencies from mix.exs - Remove Gleam configuration files (gleam.toml, src directory) - Update Dockerfile to remove mix_gleam installation - Update EncodingUtils to use Elixir module instead of Gleam - Remove Gleam references from documentation - Clean up all Gleam-related build configuration This simplifies the build process and removes the compilation issues that were preventing successful Docker builds. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- CLAUDE.md | 5 +- Dockerfile | 5 +- GLEAM_INTEGRATION.md | 85 ------------- README.md | 6 -
