External resources access from init() function may have negative side-effects like cross components initialization dependency and other initialization order issues.
For example, there is a components tree like this:
- pkg1
- pkg2
+ pkg3
lintinit will report pkg1 usages (global variables or function calls) from pk2 init() function but allow to use everything from pkg3.
Installing
go get -u github.com/astavonin/lintinit
How to run
