rio 1.2.1

• Roll back the decision to add parquet in the import tier see #455 #315

rio 1.2.0

• Fix lintr issues #434 (h/t @bisaloo Hugo Gruson)

Bug fixes

• Fix #430 Add back support for .dat

rio 1.1.1

Bug fixes

• Fix #425 for archive formats, the file extension of the input file is determined by the compressed file (like prior rio 1.1.0)

rio 1.1.0

• CRAN release

rio 1.0.3

• Add trust parameter to functions that are used to load various R environment formats (.R, .Rds, .Rdata, etc). This parameter is defaulted to TRUE today to ensure backwards compatibility. A deprecation notice warns this will default to FALSE in rio 2.0. We are informing users that these data types should only be loaded from trusted sources, which should be affirmatively attested to.
• Test and fix the compression mechanism: Gzip, Bzip2 are now working as expected.

Bug fixes

• Fix #412, prevent double usage of which for archive formats
• Fix #415, both import_list() and export_list() support tar archives.
• Fix #421, tar export is only supported by R >= 4.0.3.

rio 1.0.2

• For missing files in import_list it gives more informative warnings fix #389
• Single-item list of data frames can be exported fix #385
• Move stringi to Suggests to reduce compilation time. Add an attribution to the internal data to list out all required packages #378
• Move readr to Imports for fwf. readr is a dependency of haven so it does not increase the number of dependencies. Remove the original read.fwf2 which doesn’t guess widths. Keep the widths and col.names to maintain compatibility. #381
• Add (back) a pkgdown website: https://gesistsa.github.io/rio/
• Update all test cases #380

rio 1.0.1

• POTENTIALLY BREAKING: Due to compiling time concerns, roll back the decision to move arrow to Imports. It is now Suggests. setclass = "arrow" works if arrow is installed. #315 #376

rio 1.0.0

• Stop loading the entire namespace of a suggested package when it is available #296
• Unexport objects: .import, .export, is_file_text; remove documentation for arg_reconcile #321
• Update Examples to make them more realistic #327
• Add support for qs #275 h/t David Schoch
• Use arrow to import / export feather #340
• export_list can write multiple data frames to a single archive file (e.g. zip, tar) or a directory #346 h/t David Schoch
• get_info is added #350
• POTENTIALLY BREAKING: setclass parameter is now authoritative. Therefore: import("starwars.csv", data.table = TRUE, setclass = "tibble") will return a tibble (unlike previous versions where a data.table is returned). The default class is data frame. You can either explicitly use the setclass parameter; or set the option: options(rio.import.class = "data.table"). h/t David Schoch #336
• Parquet and feather are now formats supported out of the box; Possible to setclass to arrow / arrow_table; ArrowTabular class can be exported #315
• Add “extension”, “labelled” vignettes
• Support readODS 2.1.0 features such as reading and writing Flat ODS; export Multiple data frames #358
• POTENTIALLY BREAKING: Use writexl instead of openxlsx. Option to read xlsx with openxlsx (i.e. import("starwars.xlsx", readxl = FALSE)) is always TRUE. The ability to overwrite an existing sheet in an existing xlsx file is also removed. It is against the design principle of rio.
• POTENTIALLY BREAKING: The following options are deprecated: import(fread), import(readr = TRUE), import(haven), import(readxl) and export(fwrite). import will almost use data.table, haven, readxl, and internal function (for fwf) to import and export data. Currently, those options stay for backward compatibility but will be removed in v2.0.0. #343 h/t David Schoch
• POTENTIALLY BREAKING: ... is handled differently. Underlying functions using “Tidy” convention (e.g. readxl::read_xlsx()) can use “Base Convention” (See the new vignette: remap). Unused arguments passed to the underlying function as ... are silently ignored by default. A new option rio.ignoreunusedargs is added to control this behavior. #326
• Bug fixes
  • … is correctly passed for exporting ODS and feather #318
  • POTENTIALLY BREAKING: JSON are exported in UTF-8 by default; solved encoding issues on Windows R < 4.2. This won’t affect any modern R installation where UTF-8 is the default. #318
  • POTENTIALLY BREAKING: YAML are exported using yaml::write_yaml(). But it can’t pass the UTF-8 check on older systems. Disclaimer added. #318
  • More check for the file argument #301
  • import_list works with single Excel/HTML/Zip online #294
  • Correct XML/HTML escaping #303
  • Create directory if it doesn’t exist #347
• Declutter
  • remove the obsolete data.table option #323
  • write all documentation blocks in markdown #311
  • remove all @importFrom #325 h/t David Schoch
  • rearrange “Package Philosophy” as a Vignette #320
  • Create a single source of truth about all import and export functions #313
  • Clarify all concepts: now there is only format #351
• New authors
  • David Schoch @schochastics

• Fix a bug related to an xml2 bug (#168, h/t Jim Hester)
• import_list() gains improved file name handling. (#164, h/t Ruaridh Williamson)
• Removed the overwrite argument from export() method for xlsx files. Instead, existing workbooks are always overwritten unless which is specified, in which case only the specified sheet (if it exists) is overwritten. If the file exists but the which sheet does not, the data are added as a new sheet to the existing workbook. (#156)

rio 0.5.7

• Import of files with the ambiguous .dat extension, which are typically text-delimited files, are now passed to data.table::fread() with a message. Export to the format remains unsupported. (#98, #155)

rio 0.5.4

• New functions characterize() and factorize() provide methods for converting “labelled” variables (e.g., from Stata or SPSS) into character or factor variables using embedded metadata. This can also be useful for exporting a metadata-rich file format into a plain text file. (#153)

rio 0.5.3

• Fixed a bug in writing to .zip and .tar archives related to absolute file paths.
• Fixed some small bugs in import_list() and added tests for behavior.
• Add .bib as known-unsupported format via bib2df::bib2df().

• Import to and export from the clipboard now relies on clipr::read_clip() and clipr::write_clip(), respectively, thus (finally) providing Linux support. (#105, h/t Matthew Lincoln)
• Added an rbind argument to import_list(). (#149)
• Added a setclass argument to import_list(), ala the same in import().
• Switched requireNamespace() calls to quietly = TRUE.

rio 0.4.26

• Further fixes to .csv.gz import/export. (#146, h/t Trevor Davis)

rio 0.4.25

rio 0.4.1

• Fixed behavior of gather_attrs() on a data.frame with no attributes to gather. (#94)
• Removed unrecognized file format error for import from compressed files. (#93)

rio 0.4.0

• CRAN Release.

rio 0.3.19

• Added a gather_attrs() function that moves variable-level attributes to the data.frame level. (#80)
• Added preliminary support for import from HTML tables (#86)

rio 0.3.18

• Added support for export to HTML tables. (#86)

rio 0.3.17

• Fixed a bug in import from remote URLs with incorrect file extensions.

rio 0.3.16

• Added support for import from fixed-width format files via readr::read_fwf() with a specified widths argument. This may enable faster import of these types of files and provides a base-like interface for working with readr. (#48)

rio 0.3.15

• Added support for import from and export to yaml. (#83)
• Fixed a bug when reading from an uncommented CSVY yaml header that contained single-line comments. (#84, h/t Tom Aldenberg)

rio 0.3.14

• Diagnostic messages were cleaned up to facilitate translation. (#57)

rio 0.3.12

• .import() and .export() are now exported S3 generics and documentation has been added to describe how to write rio extensions for new file types. An example of this functionality is shown in the new suggested “rio.db” package.

rio 0.3.11

• import() now uses xml2 to read XML structures and export() uses a custom method for writing to XML, thereby negating dependency on the XML package. (#67)
• Enhancements were made to import and export of CSVY to store attribute metadata as variable-level attributes (like imports from binary file formats).
• import() gains a which argument that is used to select which file to return from within a compressed tar or zip archive.
• Export to tar now tries to correct for bugs in tar() that are being fixed in base R via PR#16716.

rio 0.3.10

• Fixed a bug in import() (introduced in #62, 7a7480e5) that prevented import from clipboard. (h/t Kevin Wright)
• export() returns a character string. (#82)

rio 0.3.9

• The use of import() for SAS, Stata, and SPSS files has been streamlined. Regardless of whether the haven = TRUE argument is used, the data.frame returned by import() should now be (nearly) identical, with all attributes stored at the variable rather than data.frame level. This is a non-backwards compatible change. (#80)

rio 0.3.8

• Fixed error in export to CSVY with a commented yaml header. (#81, h/t Andrew MacDonald)

rio 0.3.7

• export() now allows automatic file compression as tar, gzip, or zip using the file argument (e.g., export(iris, "iris.csv.zip")).

rio 0.3.6

• Expanded verbosity of export() for fixed-width format files and added a commented header containing column class and width information.
• Exporting factors to fixed-width format now saves those values as integer rather than numeric.
• Expanded test suite and separated tests into format-specific files. (#51)

rio 0.3.5

• Export of CSVY files now includes commenting the yaml header by default. Import of CSVY accommodates this automatically. (#74)

rio 0.3.3

• Export of CSVY files and metadata now supported by export(). (#73)
• Import of CSVY files now stores dataset-level metadata in attributes of the output data.frame. (#73, h/t Tom Aldenberg)
• When rio receives an unrecognized file format, it now issues a message. The new internal .import.default() and .export.default() then produce an error. This enables add-on packages to support additional formats through new s3 methods of the form .import.rio_EXTENSION() and .export.rio_EXTENSION().

rio 0.3.2

• Use S3 dispatch internally to call new (unexported) .import() and .export() methods. (#42, h/t Jason Becker)

rio 0.3.0

• Release to CRAN.
• Set a default numerical precision (of 2 decimal places) for export to fixed-width format.

rio 0.2.13

• Import stats package for na.omit().

rio 0.2.11

• Added support for direct import from Google Sheets. (#60, #63, h/t Chung-hong Chan)

rio 0.2.7

• Refactored remote file retrieval into separate (non-exported) function used by import(). (#62)
• Added test sutie to test file conversion.
• Expanded test suite to include test of all export formats.

rio 0.2.6

• Cleaned up NAMESPACE file.

rio 0.2.5

• If file format for a remote file cannot be identified from the supplied URL or the final URL reported by curl::curl_fetch_memory(), the HTTP headers are checked for a filename in the Content-Disposition header. (#36)
• Removed longurl dependency. This is no longer needed because we can identify formats using curl’s url argument.
• Fixed a bug related to importing European-style (“csv2”) format files. (#44)
• Updated CSVY import to embed variable-level metadata. (#52)
• Use urltools::url_parse() to extract file extensions from complex URLs (e.g., those with query arguments). (#56)
• Fixed NAMESPACE notes for base packages. (#58)

rio 0.2.4

• Modified behavior so that files imported using haven now store variable metadata at the data.frame level by default (unlike the default behavior in haven, which can cause problems). (#37, h/t Ista Zahn)
• Added support for importing CSVY (http://csvy.org/) formatted files. (#52)
• Added import dependency on data.table 1.9.5. (#39)

rio 0.2.2

• Uses the longurl package to expand shortened URLs so that their file type can be easily determined.

rio 0.2.1

• Improved support for importing from compressed directories, especially web-based compressed directories. (#38)
• Add import dependency on curl >= 0.6 to facilitate content type parsing and format inference from URL redirects. (#36)
• Add bit64 to Suggests to remove an import warning.

rio 0.2
