Hello,
Would you like to know how many named function parameters are used in the source files?
How do you think about to try the following semantic query approach out a bit more?
@initialize:python@
@@
import sys
import sqlite3 as SQLite
connection = SQLite.connect(":memory:")
c = connection.cursor()
c.execute("""create table numbers (number integer)""")
delimiter = "|"
def store_number(count):
"""Add an integer to an internal list."""
c.execute("""insert into numbers (number) values (?)""",
(count, )
)
@counting_parameters@
identifier work;
parameter list[number] pl;
type return_type;

return_type work(pl)

result = c.fetchone()
if result[0] > 0:

sys.stdout.write(delimiter.join( ("number", "counter") ))
sys.stdout.write("\r\n")
for result in c:
sys.stdout.write(delimiter.join((str(result[0]),

else:
sys.stderr.write("No result for this analysis!\n")
connection.close()

Do you find such an analysis result from the source files for Linux 3.17.4
interesting for further considerations?
