name: add-config-option description: Add a new configuration option to tedge_config. Use when adding a new setting to the thin-edge.io configuration in tedge.toml.

Add Configuration Option

Steps

1. Add field to define_tedge_config! macro in crates/common/tedge_config/src/tedge_toml/tedge_config.rs
2. Choose appropriate type:
   • String — free-form text
   • AbsolutePath — filesystem path
   • ConnectUrl — URL with scheme
   • SecondsOrHumanTime — duration (e.g., 30s, 5m)
   • Custom types in crates/common/tedge_config/src/tedge_toml/models/
3. Add #[tedge_config()] attributes:
   • default(value = "...") — default value
   • example = "..." — example for documentation
   • reader(...) — custom reader function
   • Other modifiers as needed
4. Add doc comment above the field — this becomes user-facing help text in tedge config
5. For custom types, add to crates/common/tedge_config/src/tedge_toml/models/
6. Verify: Run cargo test -p tedge_config
