Lua script to remove ANSI color codes

[sylr]

Hi,

Any idea how a lua script which would remove ANSI color codes from logs would look like ?

Regards.

Something like this will do:

function strip_ansi(tag, timestamp, record)
  if type(record["log"]) == "string" then
    -- strip ansi https://stackoverflow.com/a/49209650/368691
    record["log"] = record["log"]:gsub('[\27\155][][()#;?%d]*[A-PRZcf-ntqry=><~]', '')

    return 2, 0, record
  end

  return 0, 0, 0
end
