Remove Gleam and convert encoding module to pure Elixir
- 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 <noreply@anthropic.com>

# Gleam Integration Guide
|
||||
|
||||
This document describes how Gleam has been integrated into the APRS.me Elixir project.
|
||||
|
||||
## Setup
|
||||
|
||||
1. **Mix Gleam Archive**: Installed via `mix archive.install hex mix_gleam`
|
||||
2. **Dependencies**: Added to mix.exs:
|
||||
```elixir
|
||||
{:gleam_stdlib, ">= 0.60.0 and < 1.0.0", app: false, override: true},
|
||||
{:gleeunit, "~> 1.0", only: [:dev, :test], runtime: false, app: false}
|
||||
```
|
||||
3. **Project Configuration**: Added to mix.exs project config:
|
||||
```elixir
|
||||
archives: [mix_gleam: "~> 0.6"],
|
||||
erlc_paths: ["build/dev/erlang/aprsme/_gleam_artefacts", "src"],
|
||||
erlc_include_path: "build/dev/erlang/aprsme/include",
|
||||
```
|
||||
|
||||
## File Structure
|
||||
|
||||
- `/src/` - Gleam source files
|
||||
- `/src/aprs/` - APRS-specific Gleam modules
|
||||
- `/gleam.toml` - Gleam project configuration
|
||||
|
||||
## Compilation
|
||||
|
||||
The project is configured to automatically compile Gleam code when running tests or compiling:
|
||||
|
||||
```bash
|
||||
# For development
|
||||
mix compile.gleam && mix compile
|
||||
|
||||
# For tests (automatically compiles Gleam)
|
||||
mix test
|
||||
|
||||
# Manual compilation if needed
|
||||
mix gleam_compile
|
||||
```
|
||||
|
||||
The custom `gleam_compile` task handles:
|
||||
- Running the mix_gleam compiler when available
|
||||
- Falling back to the `gleam` binary if mix_gleam isn't installed
|
||||
- Copying compiled beam files to the appropriate build directory
|
||||
|
||||
## Module Naming
|
||||
|
||||
Gleam modules are compiled with `@` as the separator in BEAM files:
|
||||
- Gleam: `aprs/encoding`
|
||||
- BEAM: `aprs@encoding`
|
||||
- Elixir: `:aprs@encoding`
|
||||
|
||||
## Current Modules
|
||||
|
||||
### encoding.gleam
|
||||
|
||||
A type-safe implementation of encoding utilities:
|
||||
- `sanitize_string/1` - Ensures strings are valid UTF-8, handles Latin-1 conversion
|
||||
- `to_float_safe/1` - Safe string to float conversion with Option type
|
||||
- `to_hex/1` - Convert binary to hex string representation
|
||||
- `has_weather_data/4` - Check if packet contains weather data
|
||||
- `encoding_info/1` - Get encoding information about a binary
|
||||
|
||||
## Elixir Integration
|
||||
|
||||
The `Aprsme.EncodingUtils` module now wraps the Gleam implementation, replacing the original pure Elixir version. The Gleam implementation provides:
|
||||
- Type-safe string sanitization with Latin-1 to UTF-8 conversion
|
||||
- Proper handling of control characters
|
||||
- Safe float conversion with bounds checking
|
||||
- Consistent encoding validation
|
||||
|
||||
The migration was completed with all tests passing and no breaking changes to the API.
|
||||
|
||||
## Testing
|
||||
|
||||
The original test suite at `/test/aprsme/encoding_utils_test.exs` continues to work with the Gleam implementation:
|
||||
```bash
|
||||
mix test test/aprsme/encoding_utils_test.exs
|
||||
```
|
||||
|
||||
## Future Considerations
|
||||
|
||||
1. Add Gleam compiler to Mix.compilers() once the integration is more stable
|
||||
2. Consider migrating more type-critical modules to Gleam
|
||||
3. Explore using Gleam's type system for packet validation

- **Gleam** - Required for Gleam modules. Install from https://gleam.run/getting-started/installing/

## Setup
|

To start your Phoenix server:
|
||||
|
||||
* First install the mix_gleam archive:
|
||||
```bash
|
||||
mix archive.install hex mix_gleam --force
|
||||
```
|
