Changelog
saferDev 3.0.0
- curly_bracket_check(): new function. Verifies that all the bodies of the if, else, for, while, repeat and function are delimited by curly brackets {}. The corrected function is returned, or exported with export = TRUE.
- for_loop_nb_check(): new function. Verifies that the sequence expression of every for loop is written with hard numbers (like 1:3) or with a single seq_len() or seq_along() call. Otherwise (like 1:length(x)), a checking line is added before the loop, issuing a warning at execution if the sequence is empty, contains NA or infinite values, has a single value, or is decreasing. The corrected function is returned, or exported with export = TRUE.
- lambda_check(): new function. Verifies that the lambda functions written with the shorthand (x) are all written with the standard function(x) writing. The \ token of each reported lambda writing is replaced by function. Warning: the (x) writing is only kept in the code of a function carrying its source references (attribute srcref), so that compiled or loaded package functions cannot be checked. The corrected function is returned, or exported with export = TRUE.
- all_args_here(): a pre-check by lambda_check() is now performed: if some lambda functions written with the (x) shorthand are detected in the code of the submitted function, an error asking to run saferDev::lambda_check() first is returned.
- colons_check(): a pre-check by lambda_check() is now performed: if some lambda functions written with the (x) shorthand are detected in the code of the submitted function, an error asking to run saferDev::lambda_check() first is returned.
- lambda_check(): the parse data is now kept by the function (option keep.parse.data set to TRUE and restored on exit), so that the function does not crash anymore when it is called from a file loaded by base::sys.source(), which sets the option keep.parse.data to FALSE for the whole loading.
- true_false_check(): new function. Verifies that TRUE and FALSE are always written in full when used as values, and never abbreviated as T or F. The corrected function (T replaced by TRUE and F replaced by FALSE) is returned, or exported with export = TRUE. Warning: the pre-check of the package association of the function calls (which required running saferDev::colons_check() first) is removed: true_false_check() now only checks the T and F symbols used as values, whatever the writing of the function calls.
- colons_check(): the missing package attributions of the basic R functions are now added: the corrected function is returned, or exported with the new export and out_path arguments. These two arguments are placed before safer_check, lib_path and error_text (breaking change for calls using argument positions).
- all_args_here(): the missing arguments are now added: the corrected function is returned, or exported with the new fun_export argument. The former export argument is renamed table_export (breaking change).
- curly_bracket_check(), for_loop_nb_check(), true_false_check(), colons_check() and all_args_here(): the exported file is named
_safer.R and written in out_path (default “.”, the R working directory). It contains _safer <- function(…) …, so that base::source() recreates the corrected function. out_path cannot be NULL nor an empty string. An error is returned if the file already exists, or if the tested function is not designated by its name. A “MODIFIED CODE EXPORTED IN” message gives the file path, and NULL is returned (invisibly). - arg_check(): output component object.name renamed object_name (breaking change).
- arg_check(), env_check(), get_message(), all_args_here() and the other checking functions: dotted internal and local variable names renamed with underscores (backbone v21.0).
- colons_check() and all_args_here(): the “in” symbol is now skipped during code parsing, which prevents spurious parsing problems with for(j in (n - 1L):2L) writings.
- all_args_here(): an incoherent arg_full_names argument no longer causes a raw crash, but a proper internal error.
saferDev 2.0.0
CRAN release: 2026-10-14
- arg_check(): new behavior for the class, typeof and mode arguments. Values are now compared exactly (same values, same order) to class(data), typeof(data) and mode(data). Thus, class = “matrix” alone always returns a problem since R 4.0.0 (use class = c(“matrix”, “array”)), class = “factor” alone always returns a problem for ordered factors (use class = c(“ordered”, “factor”)), and class = “vector” is no longer a shortcut for numeric, integer, character, logical, complex or expression classes. In addition, double_as_integer_allowed = TRUE now also rescues class = “integer” when the tested object is a double with zero as modulo.
- All the safer-r functions now check that the … argument is not used, and that the reserved lib_path, safer_check and error_text arguments are present.
- R (>= 4.5.0) is now required.
