We've covered the object a little in the previous articles, so you should already be quite familiar with it.
Anyway, Contracts is the starting point of a declarative query, the highest level, and the smallest number of instances since it includes all the other objects. You can filter contracts by the following parameters:
- Names (exact, negative, prefix, suffix, regexp)
- Compiler versions (by range, e.g., 0.6.0 - 0.8.25)
- Error and event names and signatures
- Function names
- Struct names and nested types
- Interfaces or main (high-level) contracts
from glider import *
def query():
contracts = (
Contracts()
.mains()
.with_compiler_range("0.8.0", "0.8.26")
.with_struct_name("Config")
.exec(1, 1)
)
result = []
for contract in contracts:
# arbitrary logic
print(contract.source_code())
result.append(contract)
return resultCheck the first contract from the result: https://gist.github.com/ustas-eth/ff309a6a07b56fee0fda4e68caf1bb47
The pragma version is 0.8.1, and it has a struct with the name Config, too, just as requested:
struct Config {
uint256 lockupPeriod;
uint256 minAmount;
IERC20 depositedIn;
}The contract's name is DebtVault, so I assume it's supposed to keep money. It also inherits from Administrable, which seems similar to the usual Ownable, and ERC721Lite, obviously a variation of the ERC721 standard, which I never heard of. You can try to get their source codes with Contract.parent_contracts() (docs) like this:
from glider import *
def query():
contracts = (
Contracts()
.mains()
.with_compiler_range("0.8.0", "0.8.26")
.with_struct_name("Config")
.exec(1, 1)
)
result = []
for contract in contracts:
parents = contract.parent_contracts().exec()
for parent in parents:
print(parent.source_code())
result.append(contract)
return result
