cffr 1.2.0.9000

cff_gha_update() action now runs in ubuntu-latest by default to save GitHub Actions quota (#90, thanks to @Pakillo).
Improve comments detection and parsing in as_cff_person() function family.

cffr 1.2.0 (2025-01-25)

New parameter r_citation in cff_write(). When it is set to TRUE a R citation file (inst/CITATION) would be generated/updated with the information of the generated CITATION.cff file. No backup copy would be created, for more control use cff_write_citation() (#79).
repository-code now also recognizes Codeberg as a valid repository (#88).
repository-code recognizes repositories regardless of casing. It is still advised to use lower caps as a good practice for R developers.

cffr 1.1.1 (2024-08-16)

Adapt extraction of orcid to R > 4.4.1.

cffr 1.1.0 (2024-07-23)

Now cffr adds automatically dois to packages on CRAN (e.g. https://doi.org/10.32614/CRAN.package.cffr):
- If the package has a CITATION file providing a doi, the CITATION doi would be used as the main CITATION.cff doi and the CRAN doi would be added as an identifier.
- Otherwise, CRAN doi would be used as doi.
- When extracting dependencies (e.g cff_create(dependencies = TRUE) and the package dependency is on CRAN, the CRAN doi would be used for the dependency in the references key.
Extract commit from RemoteSha.
Update cran_to_spdx dataset.

cffr 1.0.1 (2024-04-09)

Update cff_write() to add a new encoding argument to make it work with different encodings, see iconv().
Fix NOTEs due to empty lines in docs.

cffr 1.0.0 (2024-03-12)

This is a major release with some notable changes. The change mainly affects to non-core functions, hence the natural workflow (cff_create() → cff_write() → cff_validate()) shouldn't be affected.

Major changes

Classes and methods

Now cffr implements a new class system for definitions.reference, definitions.person and definitions.entity objects:

List of definitions.reference (e.g, references) has class cff_ref_lst, cff and individual elements (e.g preferred-citation or each member of references) has class cff_ref, cff.
List of definitions.person or definitions.entity (e.g. authors, contact) has class cff_pers_lst, cff and individual elements (e.g publisher or each member of authors) has class cff_pers, cff.

This change allow to write specific S3 Methods and extend the capabilities of the package.

New as_cff() S3 generic method (replacing as.cff()): This method coerces R objects to cff class format. Current methods provided are:
- as_cff.Bibtex().
- as_cff.bibentry(), replacing cff_parse_citation().
- as_cff.person(), similar to as_cff_person() but only for person objects. We recommend using as_cff_person() since it can coerce also string representing authors in BibTeX markup ("{von Neumen}, James"), that can't be captured properly via methods.
New as_bibentry() method for a variety of classes (character, list, NULL and classes defined by cffr).
New as_cff_person() method.
The following base and utils methods supports now cff class:
- as.data.frame.cff().
- as.person(), although only for definitions.person or definitions.entity (e.g. authors, contacts, editors, publisher, etc.).
- head.cff(), tail.cff().
- toBibtex.cff().

API

The API has been completely reviewed to provide more clarity on functions naming and to facilitate internal maintenance. This change only affects to non-core functions. Now each function does less things but does it better. The old API has been deprecated and it would warn when used, providing advice on the replacement function.

Deprecation

cff_to_bibtex() and cff_extract_to_bibtex(): replaced by as_bibentry() S3 generic.
cff_parse_person() and cff_parse_person_bibtex(): replaced by as_cff_person() S3 generic.
cff_parse_citation(): replaced by as_cff() S3 generic.
cff_from_bibtex(): replaced by cff_read_bib() (for *.bib files) and cff_read_bib_text() (for character strings).
write_bib() and write_citation() : replaced by cff_write_bib() and cff_write_citation() respectively.
Argument path in cff() is also deprecated, use cff_read() instead.

New capabilities

Now reading from external files is performed exclusively by cff_read() (that is designed to fit all supported file types on a single entry point) and the new specific readers (that are used under the hood by cff_read()), namely:
- cff_read_cff_citation(),
- cff_read_description(),
- cff_read_citation()
- cff_read_bib().
New cff_modify() function for updating and modifying cff objects easily.

Other changes

Minimum R version required now is 4.0.0.
Update of BibTeX crosswalk (see vignette("bibtex_cff", package = "cffr")) and consequently changes in the mapping performed by as_bibtex() cff_parse_citation():
- @inbook and @book gains a new value on [CFF]{.underline} when series is provided: [collection-type: book-series.]{.underline}
- Can handle BibLaTeX @inbook, that differs significantly from BibTeX @inbook.

cffr 0.5.0 (2023-05-05)

Lifecycle

Function cff_to_bibtex() and cff_extract_to_bibtex() have been merged, the latter (cff_extract_to_bibtex()) is now soft-deprecated.

New features

New function write_citation() that can generate a inst/CITATION file from a cff object (#51).

Enhancements

Additional authors of a R package can be now included based on the role on the DESCRIPTION file, via the parameter authors_roles (#49).
New message interface based on cli capabilities.
Now the (invisible) result of cff_validate() includes the summary of errors (if any) as an attributes() named "error", as jsonvalidate::json_validate() does when verbose = TRUE:

Be verbose? If TRUE, then an attribute "errors" will list validation failures as a data.frame
Improvements in the extraction of `date-release`.

cffr 0.4.1 (2023-01-30)

cffr 0.2.0 (2022-01-04)

Now cffr extracts also information of the package dependencies and adds the main citation of the dependencies to the references field, using citation(auto = TRUE).
- New dependencies parameter on cff_create() and cff_write().
Other improvements on cff_parse_citation():
- cff_parse_citation() extracts more information of authors, based on the fields provided on the DESCRIPTION file.
- cff_parse_citation() does a better job extracting information from bibentry() /BibTeX and mapping it to preferred-citation/references fields of CFF.
Add new functions for working with git pre-commit hooks :
- cff_git_hook_install()
- cff_git_hook_remove()
New BibTeX functions:
- cff_extract_to_bibtex()
- cff_to_bibtex()
- cff_parse_person_bibtex()
