Keep wrapper signatures and the underlying `*_hourly()`, `*_daily()`, and `*_monthly()` functions in sync. Examples: + - `meteo_imgw()` -> `meteo_imgw_hourly()`, `meteo_imgw_daily()`, `meteo_imgw_monthly()` + - `hydro_imgw()` -> `hydro_imgw_daily()`, `hydro_imgw_monthly()` + - `meteo_ogimet()` -> `ogimet_hourly()`, `ogimet_daily()` + +- The package has separate ingestion paths for each upstream source family: + - **IMGW archive downloads**: archive ZIP files are downloaded from `danepubliczne.imgw.pl`, unpacked, read through `imgw_read()`, then normalized and optionally joined with built-in station metadata. + - **IMGW datastore / telemetry downloads**: `meteo_imgw_datastore()` and `hydro_imgw_datastore()` fetch large monthly telemetry archives from the datastore endpoint. These are raw, high-volume datasets and are handled separately from the archive-style IMGW functions. + - **OGIMET**: HTML is scraped with `XML::readHTMLTable`; station identity is based on WMO IDs. Hourly precipitation post-processing is handled by `precip_split()`. + - **NOAA / Wyoming**: direct file or page downloads for ISH hourly data, Mauna Loa CO2, and Wyoming soundings. + +- IMGW column renaming is a distinct normalization layer. Most IMGW functions accept `col_names = "short" | "full" | "polish"` and pass results through `meteo_shortening_imgw()` or `hydro_shortening_imgw()`. The mapping tables live in built-in datasets backed by `data-raw/`. + +- Package data and docs follow standard R package patterns: + - exported code in `R/` + - tests in `tests/testthat/` + - built-in datasets in `data/`, generated from `data-raw/` + - roxygen-generated docs in `man/` + +## Key conventions + +- Do not hand-edit `man/` or `NAMESPACE`; update roxygen comments and run `devtools::document()`. + +- Do not hand-edit `data/*.rda`; regenerate datasets from the relevant scripts in `data-raw/` and then use `usethis::use_data(...)`. + +- Preserve graceful network-failure behavior. User-facing download functions commonly keep `allow_failure = TRUE` and wrap the real worker in a `tryCatch`, while the underlying implementation lives in a `*_bp` helper. Reuse `test_url()` for download gating instead of introducing hard failures for transient network issues. + +- Tests that touch the network are written to be offline-safe. Follow the existing pattern at the top of network tests: `if (!curl::has_internet()) return(invisible(NULL))`. + +- IMGW station handling is source-specific. Meteorological IMGW archive functions expect station names in uppercase, not numeric IDs; renamed stations may need multiple names such as `c("POZNAŃ", "POZNAŃ-ŁAWICA")`. + +- Preserve the encoding fallback logic in `imgw_read()`. IMGW files vary in delimiter and encoding, so the CP1250 / UTF-8 / transliteration branches are intentional. + +- If you add a new IMGW column, update both the abbreviation source data in `data-raw/` and the runtime shortening layer in `R/meteo_shortening_imgw.R` or `R/hydro_shortening_imgw.R`. + +- If you introduce new data.table non-standard evaluation symbols, add them to `R/globals.R` to avoid `R CMD check` NOTES. + +- `R/parser.R` is the exported parser implementation.

Standard R-package layout: code in `R/`, roxygen-generated docs in `man/`, tests in `tests/testthat/`, built-in datasets in `data/` (RDAs generated from `data-raw/`), example data in `inst/extdata/`, vignettes in `vignettes/`. Minimum R is 4.1.0; documentation is generated with roxygen2 markdown mode (do not hand-edit `man/` or `NAMESPACE`). + +## Common commands + +Run from the package root in R: + +- `devtools::load_all()` — interactive load for development. +- `devtools::document()` — regenerate `man/` and `NAMESPACE` after touching roxygen blocks. +- `devtools::test()` — run the full test suite (testthat). +- `testthat::test_file("tests/testthat/test-meteo_imgw.R")` — run a single test file. +- `devtools::check()` (or `R CMD check`) — full package check; CI runs this on macOS/Windows/Ubuntu (R devel, release, 4.1). +- `lintr::lint_package()` — uses the custom `.lintr` (line length 120, cyclocomp limit 33, several default linters disabled). Respect those limits when adding code. +- `covr::package_coverage()` — coverage. Project target is 60%; `R/sounding_wyoming.R`, `R/imgw_read.R`, and `R/onAttach.R` are excluded via `.covrignore`. +- Built-in datasets are regenerated by sourcing the relevant scripts in `data-raw/` and re-running `usethis::use_data(...)`; do not edit `data/*.rda` by hand. + +## Architecture + +**Wrapper-then-implementation pattern.** Public entry points dispatch on `interval` to per-resolution implementations: `meteo_imgw()` → `meteo_imgw_hourly/daily/monthly()`, `hydro_imgw()` → `hydro_imgw_daily/monthly()`, `meteo_ogimet()` → `ogimet_hourly/daily()`. When adding a parameter to a wrapper, plumb it through every implementation it dispatches to. + +**Three independent data-source families**, each with its own download/parse path: + +- **IMGW-PIB** (Polish): downloads ZIPs from `danepubliczne.imgw.pl`, unzips, then reads CSVs through `imgw_read.R`. The reader has multi-step encoding fallbacks (CP1250, UTF-8, optional `iconv ISO-8859-2 → ASCII//TRANSLIT`); preserve those branches when editing — Polish station names contain diacritics and station files vary in delimiter/encoding. Stations are selected by NAME in capital letters (e.g. `"POZNAŃ"`), not by numeric ID. Some renamed stations require multiple names, e.g. `c("POZNAŃ", "POZNAŃ-ŁAWICA")`. Metadata lives in the built-in `imgw_meteo_stations` / `imgw_hydro_stations` datasets and in `R/clean_metadata_*.R`. +- **OGIMET**: HTML scraping via `XML::readHTMLTable` from `ogimet.com`. Stations are identified by WMO ID. `precip_split` / `R/precip_split.R` handles 6/12/24h precipitation disaggregation for hourly data. +- **NOAA / Wyoming**: direct file downloads (ISH gzipped fixed-width, CO2 text, sounding HTML). + +**Column-name shortening layer.** Most IMGW download functions accept `col_names = "short" | "full" | "polish"` and pass the raw frame through `meteo_shortening_imgw()` / `hydro_shortening_imgw()` (in `R/*_shortening_imgw.R`). Full and short names are looked up against `imgw_meteo_abbrev` / `imgw_hydro_abbrev` (built-in data). When you add a new IMGW column, update both the abbrev table (`data-raw/`) and the shortener. + +**Graceful network failure** is required for CRAN. Use `test_url()` (`R/test_url.R`) to gate downloads, and follow the existing `allow_failure = TRUE` pattern: wrap the real worker (`*_bp` "best practice" inner function) in `tryCatch` so user-facing functions return `NULL`/`invisible()` with a `message()` instead of erroring. Tests follow the same convention — every network test starts with `if (!curl::has_internet()) return(invisible(NULL))`. Don't add tests that fail when offline. + +**Other notes.** +- `R/globals.R` holds `utils::globalVariables(...)` declarations needed because of data.table's NSE; add new NSE symbols there to keep `R CMD check` clean. +- `R/onAttach.R` prints a startup message; it's covr-ignored and behind `interactive() && runif < 0.25`. +- `inst/parser.R` and `R/parser.R` exist separately — `R/parser.R` is the exported package function; `inst/parser.R` is a sandbox script (currently untracked per `git status`).
