In 1Edtrujillo1/udeploy: Back-end & Front-end functions

Description

Obtain a specific regex to apply in a vector or column

Usage

obtain_regex(
  pattern = NULL,
  return_regex = c("starts_with_pattern", "not_starts_with_pattern",
    "ends_with_pattern", "not_ends_with_pattern", "before_pattern", "after_pattern",
    "between_pattern", "contains_pattern", "not_contains_pattern", "extract_pattern",
    "not_extract_pattern", "or", "special_chrs", "regex_dates")
)

Arguments

pattern	based on this string we obtain the regex.
return_regex	choice of regex you want to obtain.

Details

This function allows you to obtain a regex based on your necesities with the intention that you do not focus on the regex part.

Value

This function return different results based on return_regex argument.

Note

• If return_regex = "or", then pattern could be a vector of length greater or equal to 1.

• If return_regex = "between_pattern", then pattern needs to be a vector of length 2.

• If return_regex = "special_chrs" or return_regex = "regex_dates", then we do not need to specify pattern, since we are going to return a vector of specific regexes.

• Other case the pattern needs to have length greater or equal to 1.

• If you want to get the regex inside another regex you need to apply more than once this function, since the output is only based on pattern
