(Need help) AST parser fails due to missing "ast" field

[TilakMaddy]

Step 1. Nuke the ~/.svm folder (where foundry installs solc)
Step 2. foundryup
Step 3. forge build

Then AST parser fails

Sample of the output of cli/reportgen.sh

Any help is greatly appreciated : )

I am concerned that for nyth projects, in the testing section we pass the path to json file. Can this be something we can avoid ?

[TilakMaddy]

@alexroan It appears to me that the new format of json files output by solc doesn't contain ast node

example :

Error reading Foundry output file: /XXX/tests/contract-playground/out/Counter.sol/Counter.json: missing field `ast` at line 1 column 7588
Error reading Foundry output file: /XXX/tests/contract-playground/out/2/Nested.sol/Nested.json: missing field `ast` at line 1 column 4285

I am finding it difficult to reproduce json output

Do you mind taking a look at it ?

[alexroan]

Ah this could have been caused by this: #183

Some AST Nodes don't actually have an ID field @TilakMaddy . This error may be occurring during the parent->child link construction where IDs are crucial.

You're right, output files don't actually produce an AST object in the json after running foundryup

foundry-rs/foundry#7197 <- Here's the culprit

I've added this PR to fix this issue: #192

[TilakMaddy]

Thanks Alex, for showing me where it originated!

[gakonst]

Sorry about that folks - we should have notified users!

[TilakMaddy]

Helloi @gakonst ! It's okay ... It's been fixed now : )

I have a small question for you. Would greatly appreciate any thoughts.

So right now, we're shelling out forge build --ast to generate the out folder with all the contracts' jsons.

I was wondering if it's possible that we can use forge codebase as a rust dependency somehow in the Cargo.toml file and make this operation happen ...

What do you think ? Good idea / bad idea / doesn't matter....haha which one is it.:P ??

[alexroan]

I like where your head is at. Perhaps open an issue/PR in the foundry codebase @TilakMaddy ?
