### Build packaging scripts

### Application tools

## L is a language identifier or a comma-separated list of them, to
## filter tests by language. T is a test type (run, repl, lsp, format,
## etc.) or a set of them to filter tests that way. If both filters
## are provided, then only tests matching both are run.

test: # [L=<lang>[,...]] [T=<test>[,...]] : Run test(s) for language or test category
	node backend/test-runner.js

## Functions such as 'repl', 'run', 'format', etc. are available in
## the sandbox, and initial setup has already been done (e.g. 'setup'
## command, template code written to main).

sandbox: # L=<lang> : Run isolated shell with per-language setup
	@: $${L}
	L=$(L) node backend/sandbox.js

## L can be either a language ID or a (quoted) custom command to start
## the LSP. This does not run in a sandbox; the server is started
## directly in the current working directory.

lsp: # L=<lang|cmd> : Run LSP REPL for language or custom command line
	@: $${L}
	node backend/lsp-repl.js $(L)

### Fetch artifacts from registries

download: # L=<lang> T=<type> : Download last published .deb from S3
	@: $${L} $${T} $${S3_BUCKET}

	aws s3 cp $(S3_DEB) $(BUILD)/$(DEB)

undeploy: # Pull latest deployment config from S3
	mkdir -p build
	aws s3 cp $(S3_CONFIG) build/config.json

### Publish artifacts to registries

push: # I=<image> : Push Riju image to Docker registry
	@: $${I} $${DOCKER_REPO}
	docker tag riju:$(I) $(DOCKER_REPO):$(I)
	docker push $(DOCKER_REPO):$(I)

deploy-latest: # Upload deployment config to S3 and update ASG instances
	aws s3 cp build/config.json $(S3_CONFIG)

deploy: deploy-config deploy-latest # Shorthand for deploy-config followed by deploy-latest

### Code formatting

fmt-c: # Format C code
	git ls-files | grep -E '\.c$$' | xargs clang-format -i

fmt-go: # Format Go code
	git ls-files | grep -E '\.go$' | xargs gofmt -l -w

fmt: fmt-c fmt-go fmt-python fmt-terraform fmt-web # Format all code

### Infrastructure

packer: supervisor # Build and publish a new webserver AMI
	tools/packer-build.bash

deploy-alerts: # Deploy alerting configuration to Grafana Cloud
	envsubst < grafana/alertmanager.yaml > grafana/alertmanager.yaml.out

### Miscellaneous

## Run this every time you update .gitignore or .dockerignore.in.

## You need to be inside a 'make env' shell whenever you are running
## manual commands (Docker, Terraform, Packer, etc.) directly, as
## opposed to through the Makefile.
