Proposal: Add variables to msg namespace #138

Closed pyAndr3w closed 1 year ago

pyAndr3w commented 1 year ago

Adding these two variables will allow:

Find out how many coins were spent on forward (gas management)
Implement custom logic with message cell. (flexibility)

msg.forwardFee

msg.forwardFee (varUint16)

Returns:

forward fee of the message for internal message.
import fee of the message for external message.

msg.cell

msg.cell (TvmCell)

Returns:

Message X cell

this will be really useful for gas/value calculation in dapps. please prioritise this issue.

@pyAndr3w This is definitely a valuable suggestion, thank you! I think we should implement separate msg.forwardFee and msg.importFee or/and provide access to Message X cell to allow parse these values independently. If msg.forwardFee returns the import fee in external messages, it would be unexpected behavior.

Implemented in 0.71.0 (2023-07-20) #141
