# Extended "nogo" analysis
This package provides a build aspect that perform nogo analysis. This will be
automatically injected to all relevant libraries when using the default
`go_binary` and `go_library` rules.
It exists for several reasons.
* The default `nogo` provided by bazel is insufficient with respect to the
possibility of binary analysis. This package allows us to analyze the
generated binary in addition to using the standard analyzers.
* The configuration provided in this package is much richer than the standard
`nogo` JSON blob. Specifically, it allows us to exclude specific structures
from the composite rules (such as the Ranges that are common with the set
types).
* The bazel version of `nogo` is run directly against the `go_library` and
`go_binary` targets, meaning that any change to the configuration requires a
rebuild from scratch (for some reason included all C++ source files in the
process). Using an aspect is more efficient in this regard.
* The checks supported by this package are exported as tests, which makes it
easier to reason about and plumb into the build system.
* For uninteresting reasons, it is impossible to integrate the default `nogo`
analyzer provided by bazel with internal Google tooling. To provide a
consistent experience, this package allows those systems to be unified.
To use this package, import `nogo_test` from `defs.bzl` and add a single
dependency which is a `go_binary` or `go_library` rule.
