Makefile to render all mermaid diagrams in the directory it is placed in.

Makefile-mermaid

src_files := $(wildcard *.mmd)
out_files := $(patsubst %.mmd,output/%.png,$(src_files))

.PHONY: all clean

all: $(out_files)

output/%.png: %.mmd
	mkdir -p $(dir $@)
	mmdc -c ./mermaidconfig.json \
		-i $< \
		-o $@

clean:
	rm output/*.png

mermaidconfig.json

{
  "theme": "default"
}

Hey,
thanks for sharing your work.
I modified it a little bit, so that the build is only run when the origin-diagram changed and clean only deletes the images in output not the whole folder.

src_files := $(wildcard *.mmd)
out_files := $(patsubst %.mmd,output/%.png,$(src_files))

.PHONY: all clean

all: $(out_files)

output/%.png: %.mmd
	mkdir -p $(dir $@)
	mmdc -c ./mermaidconfig.json \
		-i $< \
		-o $@

clean:
	rm output/*.png

mermaidconfig.json:

{
    "theme": "default"
}

@Enough7 You are welcome! Thanks of the modification. I have also updated the gist with your suggestions.
