##@ Compilation
build: ## Cross compile for Darwin and Linux
	@GOOS=darwin GOARCH=arm64 go build -o ./bin/darwin/$(BINARY_NAME)-arm64 main.go
	@GOOS=linux GOARCH=amd64 go build -o ./bin/linux/$(BINARY_NAME)-amd64 main.go

clean: ## Remove binary files
	@go clean
	@rm -f ./bin/darwin/$(BINARY_NAME)
	@rm -f ./bin/linux/$(BINARY_NAME)

##@ Rendering
# Example: make render/env-brace.json
render-brace/%: export PGPASSWORD=pass1234
render-brace/%: build ## Render file (e.g., make render/env-brace.json)
	@./bin/$(UNAME_S)/$(BINARY_NAME) $(notdir $@)

# Example: make render/env-brace.json
render-square/%: export PGPASSWORD=pass1234
render-square/%: build ## Render file (e.g., make render/env-square.json)
	@./bin/$(UNAME_S)/$(BINARY_NAME) -s $(notdir $@)
