Changelog

Source: NEWS.md

vroom 1.6.5

  • Internal changes requested by CRAN around format specification (#524).

vroom 1.6.4

CRAN release: 2023-10-02

  • It is now possible (again?) to read from a list of connections (@bairdj, #514).

  • Internal change for compatibility with cpp11 >= 0.4.6 (@DavisVaughan, #512).

vroom 1.6.3

CRAN release: 2023-04-28

  • No user-facing changes.

vroom 1.6.2

  • There was no CRAN release with this version number.

vroom 1.6.1

CRAN release: 2023-01-22

  • str() now works in a colorized context in the presence of a column of class integer64, i.e. parsed with col_big_integer() (@bart1, #477).

  • The embedded implementation of the Grisu algorithm for printing floating point numbers now uses snprintf() instead of sprintf() and likewise for vroom’s own code (@jeroen, #480).

vroom 1.6.0

CRAN release: 2022-09-30

  • vroom(col_select=) now handles column selection by numeric position when id column is provided (#455).

  • vroom(id = "path", col_select = a:c) is treated like vroom(id = "path", col_select = c(path, a:c)). If an id column is provided, it is automatically included in the output (#416).

  • vroom_write(append = TRUE) does not modify an existing file when appending an empty data frame. In particular, it does not overwrite (delete) the existing contents of that file (https://github.com/tidyverse/readr/issues/1408, #451).

  • vroom::problems() now defaults to .Last.value for its primary input, similar to how readr::problems() works (#443).

  • The warning that indicates the existence of parsing problems has been improved, which should make it easier for the user to follow-up (https://github.com/tidyverse/readr/issues/1322).

  • vroom() reads more reliably from filepaths containing non-ascii characters, in a non-UTF-8 locale (#394, #438).

  • vroom_format() and vroom_write() only quote values that contain a delimiter, quote, or newline. Specifically values that are equal to the na string (or that start with it) are no longer quoted (#426).

  • Fixed segfault when reading in multiple files and the first file has only a header row of column names, but subsequent files have at least one row (#430).

  • Fixed segfault when vroom_format() is given an empty data frame (#425)

  • Fixed a segfault that could occur when the final field of the final line is missing and the file also does not end in a newline (#429).

  • Fixed recursive garbage collection error that could occur during vroom_write() when output_column() generates an ALTREP vector (#389).

  • vroom_progress() uses rlang::is_interactive() instead of base::interactive().

  • col_factor(levels = NULL) honors the na strings of vroom() and its own include_na argument, as described in the docs, and now reproduces the behaviour of readr’s first edition parser (#396).

vroom 1.5.7

CRAN release: 2021-11-30

vroom 1.5.6

CRAN release: 2021-11-10

vroom 1.5.5

CRAN release: 2021-09-14

vroom 1.5.4

CRAN release: 2021-08-05

vroom 1.5.3

CRAN release: 2021-07-14

  • vroom(col_types=) now truncates the column types if the user passes too many types. (#355)

  • vroom() now always includes the last row when guessing (#352)

  • vroom(trim_ws = TRUE) now trims field content within quotes as well as without (#354). Previously vroom explicitly retained field content inside quotes regardless of the value of trim_ws.

vroom 1.5.2

CRAN release: 2021-07-08

  • vroom() now supports inputs with unnamed column types that are less than the number of columns (#296)

  • vroom() now outputs the correct column names even in the presence of skipped columns (#293, tidyverse/readr#1215)

  • vroom_fwf(n_max=) now works as intended when the input is a connection.

  • vroom() and vroom_write() now automatically detect the compression format regardless of the file extension for bzip2, xzip, gzip and zip files (#348)

  • vroom() and vroom_write() now automatically support many more archive formats thanks to the archive package. These include new support for writing zip files, reading and writing 7zip, tar and ISO files.

  • vroom(num_threads = 1) will now not spawn any threads. This can be used on as a workaround on systems without full thread support.

  • Threads are now automatically disabled on non-macOS systems compiling against clang’s libc++. Most systems non-macOS systems use the more common gcc libstdc++, so this should not effect most users.

vroom 1.5.1

CRAN release: 2021-06-22

  • Parsers now treat NA values as NA even if they are valid values for the types (#342)

  • Element-wise indexing into lazy (ALTREP) vectors now has much less overhead (#344)

vroom 1.5.0

CRAN release: 2021-06-14

Major improvements

  • New vroom(show_col_types=) argument to more simply control when column types are shown.

  • vroom(), vroom_fwf() and vroom_lines() now support multi-byte encodings such as UTF-16 and UTF-32 by converting these files to UTF-8 under the hood (#138)

  • vroom() now supports skipping comments and blank lines within data, not just at the start of the file (#294, #302)

  • vroom() now uses the tzdb package when parsing date-times (@DavisVaughan, #273)

  • vroom() now emits a warning of class vroom_parse_issue if there are non-fatal parsing issues.

  • vroom() now emits a warning of class vroom_mismatched_column_name if the user supplies a column type that does not match the name of a read column (#317).

  • The vroom package now uses the MIT license, as part of systematic relicensing throughout the r-lib and tidyverse packages (#323)

Minor improvements and fixes

vroom 1.4.0

CRAN release: 2021-02-01

  • vroom() no longer truncates the last value in a file if the file contains windows newlines but no final newline (#219).

  • vroom_fwf() now verifies that the positions are valid, namely that the begin value is always less than the previous end (#217).

  • vroom_lines() gains a locale argument so you can control the encoding of the file (#218)

  • vroom_write() now supports the append argument with R connections (#232)

vroom 1.2.0
