Advanced tools
Commandline console for Ethereum nodes.
ethconsole
connects to a running Ethereum node via IPC/WS/HTTP
and provides an interactive javascript console containing the web3
(1.x) object with admin extensions.
Note that the admin/debug additions are not yet official and may change over time.
Run $ ethconsole --help
for help.
$ npm install -g ethereum-console

$ ethconsole
ETHEREUM CONSOLE
Connecting to node at /Users/xyz/Library/Ethereum/geth.ipc
... Connection successful!
Use the "web3" object to interact.

ethconsole
provides access to the cpp-ethereum test interface, which can
be used to test smart contracts that depend on timing and blocks being
mined.
# Install the development version of cpp-ethereum on Ubuntu:
# sudo add-apt-repository -y ppa:ethereum/ethereum-qt
# sudo add-apt-repository -y ppa:ethereum/ethereum
# sudo add-apt-repository -y ppa:ethereum/ethereum-dev
# sudo apt-get -y update
# sudo apt-get -y install eth
#
# Start eth in test-mode using data directory /tmp/test
$ eth --test -d /tmp/test &
# Wait for it to start up...
# Run the example:
$ ethconsole /tmp/test/geth.ipc cppTestExample.js
These testing interfaces exist in cpp-ethereum:
web3.test.setChainParams({}, cb(err, bool))
set chain parameters using the json chain description
you can use the function chainParams() from the cppTestExample.js to create such a description
web3.test.mineBlocks(x, cb(err, bool))
start mining and stop again after exactly x blocks
web3.test.modifyTimestamp(x, cb(err, bool))
set the timestamp of the current block to x
web3.test.rewindToBlock(x, cb(err, bool))
rewind the blockchain to block number x
web3.test.addBlock(x, cb(err, bool)
inject an RLP-encoded block
