# Tools #

# The tools required to build and test the project come from three sources:
# 1. .bingo/Variables.mk: tools that are orthogonal to OLM, e.g.
#   - golangci-lint
#   - helm
#   - kind
#   - setup-envtest
#   - yq
# 2. go.mod/tools.go: imports testing libraries, modules that need to be vendored and/or have a low tolerance for skew with the main module
#                     or because they are already imported by the main module but we want to pull down the whole dependency
#                     to run some cmd or script, or get some resource (e.g. CRD yaml files).
#   - OLM API CRDs
#   - Code generation tools, e.g. k8s.io/code-generator

# bingo manages the type 1 tools. If
#  a) we don't want their dependencies affecting ours, and
#  b) the tool's version doesn't need to track closely with OLM
# the tool goes here
include .bingo/Variables.mk

# go.mod/tools.go manages type 2 tools. If
# a) we use the library for development, e.g testing, assertion, etc.
# b) we need some resource (e.g. yaml file)
# c) need to run a script that is in the library
# c) need to track tools closely with OLM (e.g. have the same k8s library version)
# the tools belongs in go.mod. If your normal imports don't pull down everything you need into vendor
# then add the import to tools.go
# Note: The code generation tools are either being used in go:generate directives or
# they are setup in a different script, e.g. ./scripts/update_codegen.sh
