Converting os_log to Logger via RegEx

os_log\(\s*".*"\s*,\nlog: ((self\.)?log), type: \.((fault|error|debug|info))[^\)]*\)

os_log\(\s*".*"\s*,\s*log: ((self\.)?log),\s*type: \.((fault|error|debug|info))[^\)](?!=\n)*\) // figuring out the look ahead. Need to match all non ) that

os_log\(\s*".*"\s*,\s*log: ((self\.)?log),\s*type: \.((fault|error|debug|info))([^\)]?!\)|(.|\n)*
([^\)]?!\)|(.|\n)* // match everything except close parethesis unless the close paren is not followed by a close paren



// paren not preceded by a paren
(?<!\))\)


// Getting close
os_log\(\s*".*"\s*,\s*log: ((self\.)?log),\s*type: \.(fault|error|debug|info)((\)(?=\)))|[^)])*

doesn't match:
        os_log("Setting live flag to %{public}@ for %{public}d instances",
               log: log,
               type: .info,
               String(describing: value), instances.count)

Explanation, matches all close parens followed by other parens, but not close parens followed by a comma
Needs to match all close parens that aren't followed by another close paren. Negative look ahead should be good for this

// paren 
\)(?!\)) not follwed by a paren


// I think this is it
os_log\(\s*".*"\s*,\s*log: ((self\.)?log),\s*type: \.(fault|error|debug|info)((\)(?=\)))|\)(?=\))|.|\n)*?\)(?!\))

Nope, doesn't match this:
os_log("Looking for live instances with startTime <= %{public}@ and endTime >= %{public}@", log: log, type: .debug, String(describing: startTime), String(describing: endTime))

// This made progress, note that it captures the end white space:
os_log\(\s*".*"\s*,\s*log: ((self\.)?log),\s*type: (\.(fault|error|debug|info))((\)(?=\)))|\)(?=\))|.|\n)*?(\)(?!\))\s)
                           group 1                 group 3

// Wonder if you could capture the argument patterns, really starting to get into needing a dynamic code around the regex if you wanted to automat back filling


Figuring out capture groups:
os_log(\(\s*".*")\s*,\s*log: ((self\.)?log),\s*type: \.(fault|error|debug|info)(((\)(?=\)))|\)(?=\))|.|\n)*?)(\)(?!\))\s)
                             $2                      $4

$2.$4$1

Yields: log.debug("%{public}@"

Need to insert everything after `type: .thing`


os_log(\(\s*".*")\s*,\s*log: ((self\.)?log),\s*type: \.(fault|error|debug|info)(((\)(?=\)))|\)(?=\))|.|\n)*?)(\)(?!\))\s)
$2.$4$1$5$8
