diff_str: Compare two character strings, character by character

In cli: Helpers for Developing Command Line Interfaces

Compare two character strings, character by character

Description

Characters are defined by UTF-8 graphemes.

Usage

diff_str(old, new, max_dist = Inf)

Arguments

old	First string, must not be NA.
new	Second string, must not be NA.
max_dist	Maximum distance to consider, or Inf for no limit. If the LCS edit distance is larger than this, then the function throws an error with class "cli_diff_max_dist". (If you specify Inf the real limit is .Machine$integer.max but to reach this the function would have to run a very long time.)

Value

A list that is a cli_diff_str object and also a cli_diff_chr object, see diff_str for the details about its structure.

str2 <- "PREabcdefgMIDDLEnopqrstuvwxyzPOST"
diff_str(str1, str2)
