Release v2.1.2

• flatten now merges files with dependencies first so the file will compile.
• fixed the to slot number of strings and bytes that are > 32 bytes

Release v2.1.1

• Fixed incorrect sizing of fixed-sized arrays that contained dynamic arrays. eg bool[][3][2] 2 * 3 = 6 slots, not 1
• storage diagrams now include arrays
• set a default filename for class and storage diagrams.
• Added SCAN_API_KEY env variable for the apiKey option
• slot hex values now upper case and in Courier New font so the hex data are aligned.
• don't display slot values for mappings or fixed-sized arrays
• flatten sub-command now comments out import statements and renames SPDX-License-Identifier to SPDX--License-Identifier so the merged file will compile

Release v2.1.0

• Option to add storage slot values that are fetched from the chain to storage diagrams
• Unallocated bytes now shown in storage diagrams
• fix storage diagrams when the first variable uses multiple slots
• fix: imports of @ packages when using Etherscan to get source files
• Simplified default filenames

Breaking changes from 2.0.x

• renamed the --contractName <value> option to just --contract <name>

Release v2.0.5

• Storage diagrams now support fixed-sized arrays that are declared with a constant

Release v2.0.4

Improved the default output file name when not specified. It now uses the contract name in the current working directory with the appropriate file extension.

Release v2.0.3

• Added sepolia to the network option

Release v2.0.2

• Added lib/utils files to npm package

Release v2.0.1

• Fixed finding inherited contracts for storage diagrams
• Bumped version to v2.0.1

Release 2.0.0

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.

Release v1.1.26

• Added support for file-level structs and enums which Solidity introduced in 0.6.x
• Updated dependencies
