352Oh, did you know that we automatically fetch a matching remote compiler when you change the solidity pragma? It is as easy as typing pragma solidity 0.5.0 and solidity-shell will do the rest 🙌.
Hints
pragma solidity <version>attempts to dynamically load the selected compiler version (remote compiler, may take a couple of seconds).- use
{ <statement>; }to ignore a calls return value. - Sessions can be saved and restored using the
.sessioncommand. Your previous session is always stored and can be loaded via.session load previous(not safe when running concurrent shells). .resetcompletely removes all statements..undoremoves the last statement.- See what's been generated under the hood? call
.dump. - Settings are saved on exit (not safe when running concurrent shells). call
config set <key> <value>to change settings like ganache port, ganache autostart, etc. $_is a placeholder for the last known result. Feel free to use that placeholder in your scripts :)- Special commands are dot-prefixed. Everything else is evaluated as Solidity code.
import "<path>"assumes thatpathis relative to the current working-dir (CWD) or{CWD}/node_modules/. There's experimental support for HTTPs URL's. You can disable https resolving by setting» .config set resolveHttpImports false.

Cmdline Passthru
Any arguments provided after an empty -- are directly passed to ganacheCmd (default: ganache-cli). This way, for example, you can start a solidity shell on a ganache fork of mainnet via infura. Check ganache-cli --help for a list of available options.
⇒ solidity-shell -- --fork https://mainnet.infura.io/v3/yourApiToken

📚 Help:
-----
$_ is a placeholder holding the most recent evaluation result.
pragma solidity <version> to change the compiler version.
General:
.help ... this help :)
.exit ... exit the shell
Source:
.fetch
interface <address> <name> [chain=mainnet] ... fetch and load an interface declaration from an ABI spec on etherscan.io
.inspect
bytecode ... show bytecode of underlying contract
opcodes ... show disassembled opcodes of underlying contract
storageLayout ... show variable to storage slot mapping for underlying contract
storage <slot> <num> [<address>] ... show raw storage at slot of underlying deployed contract
deployed ... debug: show internal contract object
Blockchain:
.chain
restart ... restart the blockchain service
set-provider <fork-url> ... "internal" | <shell-command: e.g. ganache-cli> | <https://localhost:8545>
- fork url e.g. https://mainnet.infura.io/v3/yourApiKey
accounts ... return eth_getAccounts
eth_<X> [...args] ... initiate an arbitrary eth JSONrpc method call to blockchain provider.
Settings:
.config ... show settings
set <key> <value> ... set setting
unset <key> ... unset setting
Session:
.session ... list sessions
load <id> ... load session
save <id> ... save session
.undo ... undo last command
.reset ... reset cmd history. start from scratch.
Debug:
.proc ... show processes managed by solidity-shell (ganache)
.dump ... show template contract
.echo ... every shell needs an echo command
cheers 🙌
