/* @flow strict */ On all source files

Question

With all=true i can make flow check all files. How do i expand this to strictly checking all files?

My current .flowconfig:

[ignore]
.*/node_modules/.*

[libs]
flow-typed

[options]
all=true
module.use_strict=true

[strict]
nonstrict-import
unclear-type
unsafe-getters-setters
untyped-import
untyped-type-import

The last strict part is not applied unless i type /* @flow strict */ in files. I want to avoid adding a comment to all files if possible :)

Answer 1

My question got answered on github:

As far as I understand strict, it's actually just setting all of the lints in [strict] to error. Try changing the [strict] section to [lints] and add =error to the end of each line. So:

[lints]
nonstrict-import=error
unclear-type=error
unsafe-getters-setters=error
untyped-import=error
untyped-type-import=error

That should set all of these lints as errors when flow type checks. Let me know if this isn't sufficient.

I'll just link the answer here: https://github.com/facebook/flow/issues/6967

Unfortunately I have not had time to test the solution provided, maybe someone else can confirm?
