Changes to the command line interface

• Class diagrams are now under a class subcommand. sol2uml class
• New storage subcommand to draw the storage slots of a contract. sol2uml storage
• New flatten subcommand that downloads the verified source code from Etherscan to a local Solidity file. sol2uml flatten

Renamed command line options

• -d --depthLimit to -sf --subfolders
• -a --hideAttributes to -hv --hideVariables
• -p --hideOperations to -hf --hideFunctions
• -e, --hideEnums to -he, --hideEnums
• -s, --hideStructs to -hs, --hideStructs
• -l, --hideLibraries to -hl, --hideLibraries
• -t, --hideInterfaces to -hi, --hideInterfaces
• -r, --hideInternals to -hp, --hidePrivates

New command line options

• Added -d --depth to limit the depth of contracts connected to the base contracts.
• Added -ha --hideAbstract to hide all abstract contracts.
• Added -hn, --hideFilename to hide the relative filename of a contract.

Dependencies

• Only support node 14 and above as TypeScript target is now ES2020
• Replaced vis.js with the maintained @aduh95/viz.js which supports Graphviz 5.0.0
• Replaced svg-to-png with the maintained convert-svg-to-png.

Fixes

• Improved linkages of classes when there are duplicate contract names, explicit imports and import aliases.
• If a contract or library contains a struct, it is marked as an aggregate association. A separate dependency line is used to link a contract to a struct. This can be a storage (solid line) or memory (dashed line) dependency.
• Structs in libraries are now linked to their dependent contract.
• Fixed the diamond inheritance problem.
• Association from an array of a user-defined type.
