Read dotenv when running chisel

[klkvr]

Motivation

RIght now, chisel ignores dotenv files (at least on startup), and this leads to it being unable to fork chain which RPC_URL is set in config via .env variable.

For example:

foundry.toml:

[profile.default]
src = "src"
out = "out"
libs = ["lib"]

[rpc_endpoints]
goerli = "${GOERLI_RPC}"

.env:

GOERLI_RPC=some_rpc

In such context chisel --fork-url goerli will fail with following error Failed to resolve env var GOERLI_RPC in ${GOERLI_RPC}: environment variable not found until the GOERLI_URL will not be explicitely set to environment via export GOERLI_RPC=some_rpc

Solution

Add utils::load_dotenv to startup of chisel

Very nice! lgtm—tested and seems correct
