git2rdata 0.5.1

• write_vc() stores metadata stored in the data frame.
• read_vc() returns more metadata.
• read_vc() can handle empty factors.
• recent_commit() now returns handles multiple commits within the same second.

git2rdata 0.5.0

• read_vc() handles empty datasets stored with split_by.
• write_vc() and meta() gain a digits argument. The arguments specifies the number of significant digits to store for numeric values.

git2rdata 0.4.1

• Add update_metadata() to update the description of a git2rdata object. See vignette("metadata") for more details.
• Update the checklist and pkgdown infrastructure.

git2rdata 0.4.0

New features

• write_vc() stores non optimised files as comma separated values rather than tab separated values. The general public seems to better recognised .csv files than .tsv files as being data files.
• Add a new function verify_vc() which reads a git2rdata object and verifies the presence of a set of variables. It return the data upon success.

Internal changes

• Upgrade to Roxygen2 7.1.2
• Add inst/CITATION, CITATION.cff, .zenodo.json

git2rdata 0.3.1

• Use icuSetCollate() to define a standardised sorting.

git2rdata 0.3.0

New features

• write_vc() gains an optional split_by argument. See vignette("split_by") for more details.
• rename_variable() efficiently renames variables in a stored git2rdata object.

Bugfixes

• read_vc(), is_git2rdata() and is_git2rmeta() now yield a better message when both the data and metadata are missing.

git2rdata 0.2.2

• Use the checklist package for CI.

git2rdata 0.2.1

Bugfixes

• Explicitly use the stringsAsFactors of data.frame() in the examples and unit tests if the dataframe contains characters. The upcoming change in default value of stringsAsFactors requires this change. See https://developer.r-project.org/Blog/public/2020/02/16/stringsasfactors/index.html

git2rdata 0.2.0

BREAKING FEATURES

• Calculation of data hash has changed (#53). You must use upgrade_data() to read data stored by an older version.
• is_git2rdata() and upgrade_data() no longer not test equality in data hashes (but read_vc() still does).
• write_vc() and read_vc() fail when file is a location outside of root (#50).
• Reordering factor levels requires strict = TRUE.

Bugfixes

• Linux and Windows machines now generated the same data hash (#49).

NEW FEATURES

• Internal sorting uses the “C” locale, regardless of the current locale.
• read_vc() reads older stored in an older version (#44). When the version is too old, it prompts to upgrade_data().
• Improve warnings() and error() messages.
• Use vector version of logo.

git2rdata 0.1

• Transfer to rOpenSci.
• Use new logo (@peterdesmet, #37).
• Add estimate of upper bound of the number of commits.

git2rdata 0.0.5

• upgrade_data() uses the same order of the metadata as write_vc().

git2rdata 0.0.4

BREAKING FEATURES

• write_vc() stores the git2rdata version number to the metadata. Use upgrade_data() to update existing data.

NEW FEATURES

• read_vc() checks the meta data hash. A mismatch results in an error.
• The meta data gains a data hash. A mismatch throws a warning when reading the object. This tolerates updating the data by other software, while informing the user that such change occurred.
• is_git2rmeta() validates metadata.
• list_data() lists files with valid metadata.
• rm_data() and prune_meta() remove files with valid metadata. They don’t touch tsv file without metadata or yml files not associated with git2rdata.
• Files with invalid metadata yield a warning with list_data(), rm_data() and prune_meta().

Bugfixes

• write_vc() and relabel() handle empty strings ('') in characters and factors (#24).
• read_vc() no longer treats # as a comment character.
• read_vc() handles non ASCII characters on Windows.

Other changes

• Use a faster algorithm to detect duplicates (suggestion by @brodieG).
• Improve documentation.
• Fix typo’s in documentation, vignettes and README.
• Add a rOpenSci review badge to the README.
• The README mentions on upper bound on the size of dataframes.
• Set lifecycle to “maturing” and repo status to “active”.
• The functions handle root containing regex expressions.
• Rework vignette("workflow", package = "git2rdata").
• Update timings in vignette("efficiency", package = "git2rdata")
• Minor tweaks in vignette("plain_text", package = "git2rdata")

git2rdata 0.0.3

• Fix typo’s in documentation, vignettes and README.

git2rdata 0.0.2

BREAKING CHANGES

• meta() appends the metadata as a list to the objects rather than in YAML format.
• yaml::write_yaml() writes the metadata list in YAML format.
• write_vc() now uses the ‘strict’ argument instead of ‘override’.
• rm_data() removes the data files. Use prune_meta() to remove left-over metadata files (#9).

NEW FEATURES

• Vignette on efficiency added (#2).
• Three separate vignettes instead of one large vignette.
  • Focus on the plain text format.
  • Focus on version control.
  • Focus on workflows.
• S3 methods replace the old S4 methods (#8).
• Optimized factors use stable indices. Adding or removing levels result in smaller diffs (#13).
• Use relabel() to alter factor levels without changing their index (#13).
• write.table() stores the raw data instead of readr::write_tsv() (#7). This avoids the readr dependency.
• write_vc() and read_vc() use the current working directory as default root (#6, @florisvdh).
• The user can specify a string to code missing values (default = NA). This allows the storage of the character string "NA".
• write_vc() returns a list of issues which potentially result in large diffs.
• list_data() returns a vector with dataframes in the repository.

Other changes

• write_vc() allows to use a custom NA string.
• Each helpfile contains a working example (#11).
• README updated (#12).
  • Updated the rationale with links to the vignettes.
  • git2rdata has a hexagon sticker logo.
  • Add the .
  • The installation instructions use remotes and build the vignettes.
• We removed auto_commit() because of limited extra functionality over git2r::commit().

git2rdata 0.0.1

NEW FEATURES

• Use readr to write and read plain text files.
• Allow storage of strings with “NA” or special characters.
• Handle ordered factors.
• Stop handling complex numbers.
