How can I generate SQL using sqlfluff?

I have the following example SQL (it gets more complex):

select    *from    (select        a,        b    from        agents)

I want to parse such a string using sqlfluff

from sqlfluff.core import Parserp = Parser(dialect='ansi')parsed = p.parse_string(query)

and split the query into two parts (and ideally into two trees/ParsedString), the outer one and the inner one. The inner query should be inserted into a CTAS statement and the outer query should reference it.

Expected pseudocode:

outer_tree.set_innermost_token('reagents')inner_tree.set_outermost_tokens('create or replace reagents as')print(outer_tree.generate_SQL())# !!! for simplicity I am removing the indentation# select * from reagentsprint(inner_tree.generate_SQL())# !!! for simplicity I am removing the indentation# create or replace reagents as select a, b from agents

Please bear in mind, this is just a simple example, I know a rudimentary regexp could help in this cases, however, I am aiming to modify more complex queries. Additionally, the SQL queries are already written, therefore I cannot go about writing only a generator.

Thanks for the pointers!

I looked at the cli.py and also on the internals of Linter, but I could only generate the same SQL code as was provided (by setting the variable filtered_source_patches to Noneon line 222).
