Graph generation fails

[spaceh3ad]

As mentioned in #137 there is an issue generating graphs for contracts that has mappings declared. Using SolidityAuditor extension I was able to generate graph for file without mappings however using cmd not.
surya grap Test.sol | dot -Tpng > Test.png output produces empty Test.png file.

I am using MacOS.
Surya version: 0.4.8
Graphviz: 9.0.0

Can you post the test Solidity file here so I can test locally, please? 🙏

now suddenly I got logs from the surya grap PositionManager.sol | dot -Tpng > Test.png

@GNSPS I tired to write minimal test for this case but it apparently worked with mapping now. I have trouble providing the minimal sample of when code fails, so I can provide link to my repo. From where the surya grap PositionManager.sol | dot -Tpng > Test.png is failing with error above.

[GNSPS]

From the error logs, I suspect the bug might be with the using for declaration and not with mappings. But I'll take a look, thanks! 🙏

[GNSPS]

Ahhh LOL, figured out quickly. I am not allowing using for declarations outside of contracts! 🙈 Back then it was not permitted in the grammar. I'll fix this.

[GNSPS]

Done! 😄 👍 Thank you for reporting it!

[GNSPS]

You can try v0.4.9

[spaceh3ad]

Thank you so much! 🎉

I am still not able to generate graphs on contracts with named mappings. I tried all the solutions on different threads but nothing seems to work. Back to manual graphs i guess

[GNSPS]

Can you post here a Solidity snippet that fails? 🙏
