irods-mermaid-trees

A script for generating mermaid diagrams from ilsresc output

rawtomermaid.py

Takes as input a file containing the output of ilsresc --ascii and a file to write the mermaid diagram to. The script will construct a mermaid diagram of the resource tree constructed in the output file.

Constructing the input file

rawtomermaid.py assumes each layer of the tree is 4 characters deeper in than the previous layer. This is true with ilsresc --ascii, but not with ilsresc by default. Constructing an input file can be done as

zone=myzone
ilsresc --ascii > ${zone}.raw

Note that since this step uses an icommand, a correct irods environment is required.

Calling rawtomermaid.py

Now that an input file exists, generating a mermaid diagram is as simple as

zone=myzone
./rawtomermaid.py --input "${zone}.raw" --output "${zone}-from-raw.md"

Putting that together to generate a mermaid diagram in a one-liner

zone="$(ienv | grep zone | cut -d' ' -f3)" ./rawtomermaid.py --input <(ilsresc --ascii) --output output-from-one-liner.md
