# xportr (development version)

* Added logging to the `domain` argument in `xportr` functions to notify user if
the domain passed doesn't exist in the metadata. (#260)

* Updated order messaging to clarify some messaging when all data in dataset is
found in the specification. (#269)

* `"hms"` was added to the default value of the `xportr.numeric_types` option.
This ensures that `{xportr}` works smoothly with variables created by
`admiral::derive_vars_dtm_to_tm()`. (#271)

* More details were added to the messages of `xportr_type()`. (#271)

# xportr 0.4.1

## New Feature

* New argument in `xportr_write()` allows users to specify the maximum file size (in GB) of their exported xpt files. (#268)
* `xportr_split()` is deprecated with this new argument above now added to `xportr_write()`

# xportr 0.4.0

## New Features

* All core functions can be run together by using new function `xportr()` (#137)
* `xportr_metadata()` can set `verbose` for a whole pipeline, i.e. setting `verbose` in `xportr_metadata()` will populate to all `xportr` functions.  (#151)
* `xportr_split()` is a new function that allows users to split a dataset into multiple output files based on a variable. (#183)
* `xportr_write()` now accepts `metadata` argument which can be used to set the dataset label to stay consistent with the other `xportr_*` functions. It is noteworthy that the dataset label set using the `xportr_df_label()` function will be retained during the `xportr_write()`. (#179)
* Added a check for character variable lengths up to 200 bytes in `xpt_validate()`(#91, #189).
* File name check is moved to strict_checks condition to allow underscores in the file name. Underscores are allowed in xpt but not per FDA requirements. (#126)
* It is now possible to get and set the xportr options using the helper function `xportr_options()` (#130)
* Added `xportr.character_metadata_types` and `xportr.numeric_metadata_types` to list the metadata types that are character or numeric. Updated `xportr.character_types` and `xportr.numeric_types` to list only the R types that are character and the R types that are numeric. This ensures that all R types, including dates, are now managed by xportr_type. If the R type differs from the metadata type, the variable is coerced (#161).
* New argument in `xportr_length()` allows selection between the length from metadata, as previously done, or from the calculated maximum length per variable when `length_source` is set to “data” (#91)
* Series of basic checks added to the `xportr_format()` function to ensure format lengths, prefixes are accurate for the variable type. Also to ensure that any numeric date/datetime/time variables have a format. (#164)
* `xportr_length()` assigns the maximum length value instead of 200 for a character variable when the length is missing in the metadata (#207)

## Bug Fixes

* Bug fix for domain filtering (#137)
* Make `xportr_type()` drop factor levels when coercing variables (#159)

## Deprecation and Breaking Changes

* The `domain` argument for xportr functions will no longer be dynamically 
determined by the name of the data frame passed as the `.df` argument. This was
done to make the use of xportr functions more explicit. (#182)
* The `metacore` argument, which was renamed to `metadata` in the following six xportr functions: (`xportr_df_label()`, `xportr_format()`, `xportr_label()`, `xportr_length()`, `xportr_order()`, and `xportr_type()`) in version `0.3.0` with a soft deprecation warning, has now been hard deprecated. Please update your code to use the new `metadata` argument in place of `metacore`. (#203)
* `SASlength` and `SAStype` were removed since they did not have an impact on `xpt_validate` or any other functions (#132)
* `adsl` data object is now called `adsl_xportr` (#237)

## Documentation

* Created development version of the website (#187)
* Additional guidance for options added in deep dive vignette (#81)
* Added a vignette about standards in different agencies (#206)
* Removed non-user facing function documentation (#192)
* Added more details about `xportr_length()` and `xportr()` to deep dive vignette (#215, #222)

## Miscellaneous

* Tests use `{withr}` to create temporary files that are automatically deleted (#219)
* Remove unused packages from Suggests (#221, #237)
* Exporting a new dataset `dataset_spec` that contains the Dataset Specification for ADSL. (#179)
* Adds argument assertions to public functions using `{checkmate}` (#175)
* Data objects are no longer lazy loaded, which means that when needed the user must call `data("name_of_object")` first (#237)

# xportr 0.3.2

* Removed unused packages, `{tm}` and `{janitor}` from Imports (#241)

# xportr 0.3.1

* Fixed issues around code coverage (#170) and `lintr` (#176)

# xportr 0.3.0

## New Features and Bug Fixes

* Fixed an issue where `xportr_type()` would overwrite column labels, widths, and "sas.formats"
* Fixed messaging of `xportr_order()`to give better visibility of the number of variables being reordered.
* Add new argument to `xportr_write()` to allow users to specify how xpt validation checks are handled.
* Fixed bug where character_types were case sensitive. They are now case insensitive (#77).
* Updated `xportr_type()` to make type coercion more explicit.
* `xpt_validate` updated to accept iso8601 date formats. (#76)
* Added function `xportr_metadata()` to explicitly set metadata at the start of a pipeline (#44)
* Metadata order columns are now coerced to numeric by default in `xportr_order()` to prevent character sorting (#149)
* Message is shown on `xportr_*` functions when the metadata being used has multiple variables with the same name in the same domain (#128)
* Fixed an issue with `xport_type()` where `DT`, `DTM` variables with a format specified in the metadata (e.g. `date9.`, `datetime20.`) were being converted to numeric, which will cause a 10 year difference when reading it back by `read_xpt()`. SAS's uniform start date is 1960 whereas Linux's uniform start date is 1970 (#142).
* Fixed an issue with R's pipe `|>` that was causing functions to abort (#97)
* Removed `<` and `>` as illegal characters in variable and dataset labels (#98)

## Documentation

* Moved `{pkgdown}` site to bootswatch. Enabled search and linked slack icon (#122).
* Additional Deep Dive vignette showcasing functions and quality of life utilities for processing `xpts` created (#84)
* Get Started vignette spruced up. Messages are now displayed and link to Deep Dive vignette (#150)
* Increase test coverage to 100% (#82)

## Deprecation and Breaking Changes

* The `metacore` argument has been renamed to `metadata` in the following six xportr functions: `xportr_df_label()`, `xportr_format()`, `xportr_label()`, `xportr_length()`, `xportr_order()`, and `xportr_type()`. Please update your code to use the new `metadata` argument in place of `metacore`.
