### Clean ###

clean:
	@cargo clean
	@rm -rf dist
	@rm -f romfs/barista.lst
	@cd library/plgldr && make clean --no-print-directory

re: clean all

# Like make re, but only forces rebuild of the binary
force:
	@rm -rf target/armv6k-nintendo-3ds/debug/build/barista-*
	@make all

### C libraries ###

plgldr:
	@make --no-print-directory -C library/plgldr


### Useful Cargo stuff ###

doc:
	@$(CARGO) doc --open $(CARGOFLAGS)

fmt:
	@cargo fmt --all

test: dist
	@$(CITRA) $(DIST)/$(CRATE_NAME).3dsx

check:
	@$(CARGO) clippy $(CARGOFLAGS)

update:
	@cargo update
