dot-has_regex_pattern: Detect a regex pattern in a character vector

In stbl: Stabilize Function Arguments

Detect a regex pattern in a character vector

Description

A wrapper around stringi::stri_detect_regex() and base::grepl() that prefers the stringi implementation if the package is available.

Usage

.has_regex_pattern(x, regex)

Arguments

x

The argument to stabilize.

regex

⁠(character, list, or stringr_pattern)⁠ One or more optional regular expressions to test against the values of x. This can be a character vector, a list of character vectors, or a pattern object from the {stringr} package (e.g., stringr::fixed("a.b")). The default error message for non-matching values will include the pattern itself (see regex_must_match()). To provide a custom message, supply a named character vector where the value is the regex pattern and the name is the message that should be displayed. To check that a pattern is not matched, attach a negate attribute set to TRUE. If a complex regex pattern throws an error, try installing the stringi package.

Value

A logical vector of matches in x to regex.
