improve cdd json parsing

[tclemos]

Motivation

Below is a call to cast cdd to decode this particular transaction:

cast cdd --json 'sequenceBatchesValidium((bytes32,bytes32,uint64,bytes32)[],uint64,uint64,address,bytes)' 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

Ideally, the first argument here, which is a tuple, would be JSON encoded as an array rather than a string:

My workaround for now has been use something like jq -r '.[0]' | tr "()" "[]" | sed -e 's/\(0x[0-9a-f]*\)/"\1"/gi' | jq '.' to parse the first argument.

Solution

Changed ./crates/cast/main.rs print_token(tokens) to parse fields into JSON objects instead of strings

@mattsse @zerosnacks would you mind checking this PR?
does it make sense from your perspective?
anything else I could help with?

Hi @tclemos thanks for your PR!

Whilst I understand the need to parse this as suggested I don't think the proposed solution is the one we are looking for as it effectively reverts the formatting applied in https://github.com/foundry-rs/foundry/blob/5c6b9ae8143bce995e52e927297429257d354ffd/crates/common/fmt/src/dynamic.rs. If we wanted to make a change to the formatting that would be place to make the change.

Personally I think the current formatting for tuples using ( .. ) is correct and consistent.
