nit: rename this variable to match the new filename too?

[ktyliu, 2017/01/29 21:22:14]

Done

   inputs = scripts_for_in_files + [

[Rick Byers, 2017/01/27 22:17:01]

this scripts_for_in_files should change too, right?  Eg. instead of
in_generator.py it should depend on json5_generator.py.  Looks like the
settings.json5 rules are missing this too.  So if someone changes the
json5_generator code, I think these won't be detected as needing rebuild.

[ktyliu, 2017/01/29 21:22:14]

good catch
added json5_generator.py to scripts_for_in_files

thanks

Where is this?  Did you forget to add build/scripts/scripts.gni to your CL?

[ktyliu, 2017/02/07 01:12:18]

Done now.

Sorry I had that added in another CL and then I rebased and therefore had no
change. But that CL was later reverted.
