`Identifier already declared` error

[x676f64]

I receive this error in solidity-shell.

It seems to occur after setting 512-bits worth of data or somewhere near there. Just doing a little quick testing, here is it happening on the 4th uint128 declaration:

Though it took three uint256's to trigger the first time.

Hmm, that's weird 🤔 This should throw a declaration error the first time you re-declare a variable.

I don't seem to be able to reproduce this. Could it be that the error is delayed from the first instance of the re-declaration? (maybe delayed by ganache; error location matches mine in the screenshot). Can you check the output of .dump after you re-declare b (this is what's being evaluated)?

Also, note that delete <var> will reset its value to default (zero for unit) and not undeclare it. You'll still get a declaration error if you attempt to declare the variable again.

Sure, here you go. It appears you're right. It's just not triggering an error the first time.

🚀 Entering interactive Solidity shell. '.help' and '.exit' are your friends.

Hey 🙌 ,

just published a new version that may fix an issue where an error wasn't returned even though it should. Can you give it a try?

Else, would be great if you could just run ganache-cli in another shell window, keep the console open. then start solidity-shell which should connect to your running ganache instance. Now try to reproduce the issue and check if there is a delay between solidity-shell and the ganache rpc calls. It does not reproduce on my local machine (macos) but if we can track it down I might be able to check what's going wrong :)

cheers

I'm closing this for now. feel free to reopen if you have more information on how to reproduce. thanks!
