Create a Baseline

[aiKrice]

It would be nice to create a baseline feature when legacy warnings are too numbered.

I was just about to request something like this also, we are integrating periphery into a codebase with thousands of LOC and it's not feasible to fix the warnings without having a baseline ignore. You might be able to make use of a short ruby script to perform an automated insert of baseline ignores.

Does not handle parameters, and doesn't do indentation correctly

# takes as input lines of warnings from periphery formatted for Xcode
# exclude parameter based warnings (cannot be handled)
File.open('warnings.txt').grep_v(/Parameter/).sort.reverse.each do |line|
  # extract location
  file=line[/(.*?):(.*?):(.*?)/, 1]
  line_num=line[/(.*?):(.*?):(.*?)/, 2]
  # insert a baseline ignore on the line above
  `sed -i '' '#{line_num}s/^/    \\/\\/ periphery:ignore - baseline ignores\\n/' "#{file}"`
end

I have been working on a very similar feature for SwiftLint, which is not in a shipping version yet, but has been merged to main - you can see more details here: realm/SwiftLint#5475

I have an implementation of this feature for Periphery as well, that I'm just working out a few kinks on.
