wciia - Whose Code Is It Anyway
|
|
Determines code owner of the file/folder relative to the llvm source root.
|
Code owner is determined from the content of the CODE_OWNERS.TXT
|
by parsing the D: field
|
|
usage:
|
|
utils/wciia.py path
|
|
limitations:
|
- must be run from llvm source root
|
- very simplistic algorithm
|
- only handles * as a wildcard
|
- not very user friendly
|
- does not handle the proposed F: field
