Changelog • stbl

stbl (development version)

New features

to_df() now handles atomic vectors provided as named objects (e.g. to_df(letters)) and provides informative error messages in additional cases, such as jagged lists (#203).
New stabilize_df() and specify_df() to validate data frame structure and contents (#142). to_df() coerces compatible inputs such as named lists to data frames.
New function to_df() (and synonym to_data_frame()) to coerce an object to a data frame (#201).
New stabilize_lst() and specify_lst() to validate list structure and contents and create pre-configured list validators for nested validation (#110).
New stabilize_present() validates that a value is non-NULL without imposing any type constraints (#110).
New expect_pkg_error_snapshot() function to snapshot-test the full error output of pkg_abort()-style errors in one step, combining expect_snapshot() with expect_pkg_error_classes() (#188).
New condition functions: pkg_abort() throws errors with a standardized, opinionated collection of classes, and expect_pkg_error_classes() checks that an error with the expected set of classes is thrown (#136).
New specification functions: specify_*() creates a “stbl-specified function” (class "stbl_specified_fn"), a call to the corresponding stabilize_*() function with arguments pre-filled. For example, stabilize_email <- specify_chr(regex = "^[^@]+@[^@]+\\.[^@]+$") creates a stabilize_email() function that calls stabilize_chr() with regex = "^[^@]+@[^@]+\\.[^@]+$", which could then be used to stabilize email addresses (#147, #148, #149, #150, #151).
New function to_lst() (and synonym to_list()) to coerce an object to a list, with conditional checks for NULL and functions (#157, #166).
New synonym functions for all class functions. For example to_character() is now a synonym for to_chr(), and specify_logical() is a synonym for specify_lgl() (#164). In addition, stabilise_*() synonyms have been added for all stabilize_*() functions (#167).

Breaking changes

to_chr_scalar(), to_dbl_scalar(), to_fct_scalar(), to_int_scalar(), to_lgl_scalar(), stabilize_chr_scalar(), stabilize_dbl_scalar(), stabilize_fct_scalar(), stabilize_int_scalar(), stabilize_lgl_scalar(), specify_chr_scalar(), specify_dbl_scalar(), specify_fct_scalar(), specify_int_scalar(), and specify_lgl_scalar() (and their synonyms) now default to allow_null = FALSE and allow_zero_length = FALSE. Pass allow_null = TRUE or allow_zero_length = TRUE to restore the previous behavior (#189, #197).

Potential breaking changes

Several conditions that formerly included a subclass of “stbl-error-must” no longer include that subclass. This only occurs when “stbl-error-must” was not the most specific subclass (i.e., when a more specific subclass was already included), and therefore should not impact most if any code (#136).

Other changes

Revised the “Getting started with stbl” vignette to clarify what happens at each step (#139, #143, #144).
Clarified error messages (#176, #177).

stbl 0.2.0

CRAN release: 2025-09-16

New features

New predicate functions check if an object can be safely coerced to a specific type. The is_*_ish() family (is_chr_ish(), is_dbl_ish(), is_fct_ish(), is_int_ish(), and is_lgl_ish()) checks the entire object at once. The are_*_ish() family (are_chr_ish(), are_dbl_ish(), are_fct_ish(), are_int_ish(), and are_lgl_ish()) checks each element of a vector individually (#23, #93).
New functions for working with doubles are available: to_dbl(), to_dbl_scalar(), stabilize_dbl(), and stabilize_dbl_scalar() (#23).
stabilize_chr() now accepts patterns from stringr::regex(), stringr::fixed(), and stringr::coll() (#87), and can generate more informative error messages for regex failures via the new regex_must_match() and regex_must_not_match() helper functions (#52, #85, #86, #89).

Minor improvements and fixes

Error messages are now clearer and more standardized throughout the package (#95).
to_*() functions now consistently flatten list-like inputs when no information would be lost in the process (#128).
to_fct() now lists the allowed values in its error message when a value is not in the expected set, making it easier to debug (#67).
to_lgl() now coerces character representations of numbers (e.g., “0” and “1”) to FALSE and TRUE respectively (#30).

Documentation

The purpose of and vision for this package are now more clearly described in documentation (#56, #77).
New vignette("stbl") provides an overview of the package and its functions (#42).
