# Weatherreporter Configuration Configuration is YAML. By default, `weatherreporter` reads: ```text /usr/local/etc/weatherreporter/config.yml ``` Use `--config PATH` to load a different file. If the default file is absent, built-in defaults are used. If `--config PATH` points to a missing file, loading fails. Precedence is: 1. CLI flags 2. configuration file 3. built-in defaults The CLI configuration overrides are `--units` and `--tz`. Output flags control report copies for the current command but do not change configuration files. Environment variables do not override configuration fields. ## Minimal Config See [examples/minimal-config.yml](../examples/minimal-config.yml). ```yaml weather_api: base_url: https://weather.api.example.com/ ``` `weather_api.base_url` is required for commands that fetch weather data. Other fields fall back to defaults. ## Production-Oriented Config See [examples/config.yml](../examples/config.yml). The example is loaded by the config test suite. ## Field Reference ### `weather_api` - `base_url`: absolute base URL for the Weather API. Required for generation and fetch workflows. - `timeout`: HTTP timeout duration. Default: `10s`. - `precision`: numeric precision query value. Default: `1`. - `units`: Weather API units query value. Default: `us`. - `timezone`: report timezone and Weather API timezone query value where supported. Default: `America/Chicago`. - `format`: Weather API response format. Must be `json`. Default: `json`. Timezone values may be IANA names, configured aliases such as `Chicago` and `Stl`, US timezone abbreviations, or UTC offsets such as `-5` and `+09:30`. ### `location` `location` is descriptive prompt context included in module metadata and Scriptorium data packages. It does not select a Weather API endpoint or enable multiple configured forecast locations. - `id`: short local identifier. Default: `home`. - `name`: human-readable location name. Default: `Brentwood`. - `region`: broader forecast area context. Default: `St. Louis Metro`. The prompt-facing location object also includes `timezone`, derived from the effective `weather_api.timezone` after CLI overrides such as `--tz`. ### `secrets` - `directory`: optional directory of file-backed environment secrets. Default: empty, which disables secret loading. When configured, each regular file directly under `secrets.directory` is loaded after config file parsing and CLI overrides. The file basename must be a valid environment variable name matching `[A-Za-z_][A-Za-z0-9_]*`; the file contents become the environment variable value and overwrite any existing value. One trailing LF or CRLF is stripped. Subdirectories, symlinks, invalid filenames, missing directories, and unreadable files fail config loading. ### `notify` `notify.distributor` controls distributor notification after successful report generation. It is disabled by default and does not add CLI flags. When enabled, weatherreporter uploads one distributor bundle per generated report after report rendering succeeds and final metadata is saved. - `enabled`: whether distributor notification config is active. Default: `false`. - `endpoint`: absolute distributor endpoint URL. Required when enabled. Default: `https://distributor.example.com`. - `token_env`: environment variable name that will contain the distributor upload token. Required when enabled. Default: `DISTRIBUTOR_UPLOAD_TOKEN`. - `timeout`: distributor operation timeout. Must be greater than zero when enabled. Default: `30s`. - `failure_policy`: must be `error` when enabled. Default: `error`. - `pipeline_id_template`: template for the distributor pipeline ID. Required when enabled. Default: empty. - `bundle_id_template`: template for distributor bundle IDs. Default: `weatherreporter.{location_id}.{report_id}`. - `idempotency_key_template`: template for distributor idempotency keys. Default: `{bundle_id}.{run_id}`. - `report_path_templates`: ordered list of templates for Markdown report paths inside the distributor bundle. Each rendered path maps to the same managed Markdown report source. Default: ```yaml - "{valid_start_date}/{artifact_group}/{valid_start_date}-{artifact_group}-{run_id}.md" ``` Supported template variables are `location_id`, `report_id`, `run_id`, `artifact_group`, `batch_output_name`, `valid_start_date`, `valid_end_date`, `valid_start_time`, `valid_end_time`, `valid_start_stamp`, and `valid_end_stamp`. Date values use `YYYY-MM-DD`, time values use `HHMM`, and stamp values use `YYYY-MM-DDTHHMM` in the effective report timezone. `pipeline_id_template` and `idempotency_key_template` may also use `bundle_id`. The rendered pipeline ID selects the configured distributor `http_upload` workflow. The rendered bundle ID is the stable logical source identity for the report stream. The rendered idempotency key is the per-run retry identity. Rendered report paths must be unique relative paths with `/` separators. They must not contain backslashes, empty path segments, `.`, `..`, `manifest.json`, or `.distributor.json`. The upload token is read from the environment variable named by `token_env` after config loading and `secrets.directory` processing. Config files should name the variable only; they should not contain the token value. ### `missing_source` - `default`: missing-source behavior for optional sources. One of `error`, `warn`, or `none`. Default: `warn`. - `sources`: optional map of source-specific overrides, using the same policy values. Hourly forecast data is required for generated reports. Optional sources use the missing-source policy. Source override keys include `observations`, `current`, `narrative`, `alerts`, `discussion`, `weather_story`, and `spc_convective_outlooks`. ### `scriptorium` - `binary`: `scriptorium` executable name or path. Default: `scriptorium`. - `config_path`: optional Scriptorium config path passed to the adapter. - `profile`: optional Scriptorium profile passed to the adapter. - `timeout`: subprocess timeout. Default: `2m`. - `extra_args`: optional additional arguments passed to Scriptorium commands. ### `workspace` - `root`: workspace root for managed artifacts. Default: `workspace`. - `snapshots_dir`: module snapshot and metadata directory under `workspace.root`. Default: `snapshots`. - `reports_dir`: managed Markdown report directory under `workspace.root`. Default: `reports`. - `data_packages_dir`: prompt input package directory under `workspace.root`. Default: `data-packages`. - `preflight_dir`: Scriptorium render output directory under `workspace.root`. Default: `preflight`. - `notifications_dir`: distributor notification debug artifact directory under `workspace.root`. Default: `notifications`. Workspace subdirectories must be relative paths that stay inside `workspace.root`. ### `dayparts` `dayparts` is a list of named local-time windows used by forecast derivation. Each entry has: - `name` - `start` - `end` `start` and `end` use `HH:MM`. The default entries are overnight, morning, midday, afternoon, and evening. ### `recent_change` - `temperature_degrees`: temperature change threshold. Default: `5`. - `precip_probability_points`: precipitation probability threshold. Default: `20`. - `wind_gust_miles_per_hour`: wind gust change threshold. Default: `10`. - `precip_timing_shift_minutes`: precipitation timing shift threshold. Default: `120`. Recent Changes are added to prompt input when a prior comparable module snapshot exists and a threshold is crossed. ### `reports` `reports` optionally overrides the ordered deterministic modules declared by report definitions. Omit a report entry to use its default module order. Supported report keys are `daily`, `today`, `tomorrow`, `hourly`, `three_day`, `weekend`, and `storm`. Canonical report IDs and accepted aliases are also valid, including `three_day_outlook`, `weekend_outlook`, and `storm_report`. Hyphens and underscores are treated equivalently in report keys. Retired report keys are not supported. `reports.today` applies only to the Today Report. `reports.daily` applies only to the dated Daily Report. Each report entry supports: - `deterministic_modules`: ordered module list. Entries may be string module IDs or objects with `id` and optional `options`. Example: ```yaml reports: daily: deterministic_modules: - metadata - current_conditions - narrative_forecast - alert_digest - spc_convective_outlooks - id: area_forecast_discussion options: sections: - short_term - spc_convective_discussion - daily_planning - hourly_forecast today: deterministic_modules: - metadata - current_conditions - narrative_forecast - derived_daily_summary - derived_daypart_summaries - precip_timing - alert_digest - spc_convective_outlooks - area_forecast_discussion - spc_convective_discussion - weather_story - outdoor_windows - hourly_forecast - today_planning hourly: deterministic_modules: - metadata - current_conditions - hourly_forecast - precip_timing - alert_digest - spc_convective_outlooks - id: area_forecast_discussion options: sections: - key_messages - short_term - spc_convective_discussion - weather_story ``` Unknown reports, unknown modules, duplicate modules, incompatible report/module combinations, duplicate stanza names, and invalid options fail config loading. `area_forecast_discussion.options.sections` may contain `product`, `key_messages`, `short_term`, and `long_term`. Empty or omitted `sections` includes all available AFD sections. The module registry accepts all module IDs documented in [Module Contract Internals](internal/module.md). Unknown or unimplemented module IDs fail validation instead of being skipped. ## Secrets Configuration files should not contain raw secrets. Use `secrets.directory` to load secret values from files into environment variables for integrations that read credentials from the environment. Secret file names become environment variable names, and secret file contents become values. For distributor notification, this allows a file such as `/DISTRIBUTOR_UPLOAD_TOKEN` to supply the token referenced by `notify.distributor.token_env`. ## Maintained Examples - [examples/minimal-config.yml](../examples/minimal-config.yml): smallest useful config for generation and fetching. - [examples/config.yml](../examples/config.yml): production-oriented config covering maintained fields. Both example files are loaded by the config test suite.
