Its printed output is similar to calling diff -u at the command
line.
diff_chr(old, new, max_dist = Inf)First character vector.
Second character vector.
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.)
A list that is a cli_diff_chr object, with a format() and a
print() method. You can also access its members:
old and new are the original inputs,
lcs is a data frame of LCS edit that transform old into new.
The lcs data frame has the following columns:
operation: one of "match", "delete" or "insert".
offset: offset in old for matches and deletions, offset in new
for insertions.
length: length of the operation, i.e. number of matching, deleted
or inserted elements.
old_offset: offset in old after the operation.
new_offset: offset in new after the operation.

diff-like tools.
