Support more complex String.format rewrites #6
Description
https://docs.oracle.com/en/java/javase/21/docs/api/java.base/java/util/Formatter.html#syntax
%[argument_index$][flags][width][.precision]conversion
This will be a multi-part issue, will address them on an as needed basis. The baseline %<conversion> is already supported (just as the default tostring for each type), leaving <argumentIndex>$, <flags>, <width>, and .<precision>, and any extra handling for types.
- argumentIndex support, so arg order is correct
- width for integers - using the example
String.format(Locale.US, ".%09d", nanos)from grpc-java - this requires the int/long value be written with a minimum of 9 characters - flag
0, using the same.%09d- the result will be zero padded - conversion
B/b- null should be false. - conversion
%- write the literal%
...
Items above should be converted into tickets as they are going to be addressed, new items added (make a comment below if you want something added here).
At this time, Locale will continue to not be supported, and will be removed from the expression.
