Display the current config
$ forge config --helpUsage: forge config [OPTIONS] [PATHS]...
Options:
--basic
Print only a basic set of the currently set config values
--fix
Attempt to fix any configuration warnings
-h, --help
Print help (see a summary with '-h')
-j, --threads <THREADS>
Number of threads to use. Specifying 0 defaults to the number of
logical cores
[aliases: jobs]
Build options:
--names
Print compiled contract names
--sizes
Print compiled contract sizes. Constructor argument length is not
included in the calculation of initcode size
--ignore-eip-3860
Ignore initcode contract bytecode size limit introduced by EIP-3860
--no-cache
Disable the cache
--eof
Use EOF-enabled solc binary. Enables via-ir and sets EVM version to
Prague. Requires Docker to be installed.
Note that this is a temporary solution until the EOF support is merged
into the main solc release.
--skip <SKIP>...
Skip building files whose names contain the given filter.
`test` and `script` are aliases for `.t.sol` and `.s.sol`.
[PATHS]...
Build source files from specified paths
Cache options:
--force
Clear the cache and artifacts folder and recompile
Linker options:
--libraries <LIBRARIES>
Set pre-linked libraries
[env: DAPP_LIBRARIES=]
Compiler options:
--ignored-error-codes <ERROR_CODES>
Ignore solc warnings by error code
--deny-warnings
Warnings will trigger a compiler error
--no-auto-detect
Do not auto-detect the `solc` version
--use <SOLC_VERSION>
Specify the solc version, or a path to a local solc, to build with.
Valid values are in the format `x.y.z`, `solc:x.y.z` or
`path/to/solc`.
--offline
Do not access the network.
Missing solc versions will not be installed.
--via-ir
Use the Yul intermediate representation compilation pipeline
--no-metadata
Do not append any metadata to the bytecode.
This is equivalent to setting `bytecode_hash` to `none` and
`cbor_metadata` to `false`.
--ast
Includes the AST as JSON in the compiler output
--evm-version <VERSION>
The target EVM version
--optimize [<OPTIMIZE>]
Activate the Solidity optimizer
[possible values: true, false]
--optimizer-runs <RUNS>
The number of runs specifies roughly how often each opcode of the
deployed code will be executed across the life-time of the contract.
This means it is a trade-off parameter between code size (deploy cost)
and code execution cost (cost after deployment). An `optimizer_runs`
parameter of `1` will produce short but expensive code. In contrast, a
larger `optimizer_runs` parameter will produce longer but more gas
efficient code
--extra-output <SELECTOR>...
Extra output to include in the contract's artifact.
Example keys: evm.assembly, ewasm, ir, irOptimized, metadata
For a full description, see
<https://docs.soliditylang.org/en/v0.8.13/using-the-compiler.html#input-description>
--extra-output-files <SELECTOR>...
Extra output to write to separate files.
Valid values: metadata, ir, irOptimized, ewasm, evm.assembly
Project options:
-o, --out <PATH>
The path to the contract artifacts folder
--revert-strings <REVERT>
Revert string configuration.
Possible values are "default", "strip" (remove), "debug"
(Solidity-generated revert strings) and "verboseDebug"
--build-info
Generate build info files
--build-info-path <PATH>
Output path to directory that build info files will be written to
--root <PATH>
The project's root path.
By default root of the Git repository, if in one, or the current
working directory.
-C, --contracts <PATH>
The contracts source directory
-R, --remappings <REMAPPINGS>
The project's remappings
--remappings-env <ENV>
The project's remappings from the environment
--cache-path <PATH>
The path to the compiler cache
--lib-paths <PATH>
The path to the library folder
--hardhat
Use the Hardhat-style project layout.
This is the same as using: `--contracts contracts --lib-paths
node_modules`.
[aliases: hh]
--config-path <FILE>
Path to the config file
Watch options:
-w, --watch [<PATH>...]
Watch the given files or directories for changes.
If no paths are provided, the source and test directories of the
project are watched.
--no-restart
Do not restart the command while it's still running
--run-all
Explicitly re-run all tests when a change is made.
By default, only the tests of the last modified test file are
executed.
--watch-delay <DELAY>
File update debounce delay.
During the delay, incoming change events are accumulated and only once
the delay has passed, is an action taken. Note that this does not mean
a command will be started: if --no-restart is given and a command is
already running, the outcome of the action will be to do nothing.
Defaults to 50ms. Parses as decimal seconds by default, but using an
integer with the `ms` suffix may be more convenient.
When using --poll mode, you'll want a larger duration, or risk
overloading disk I/O.
EVM options:
-f, --fork-url <URL>
Fetch state over a remote endpoint instead of starting from an empty
state.
If you want to fetch state from a specific block number, see
--fork-block-number.
[aliases: rpc-url]
--fork-block-number <BLOCK>
Fetch state from a specific block number over a remote endpoint.
See --fork-url.
--fork-retries <RETRIES>
Number of retries.
See --fork-url.
--fork-retry-backoff <BACKOFF>
Initial retry backoff on encountering errors.
See --fork-url.
--no-storage-caching
Explicitly disables the use of RPC caching.
All storage slots are read entirely from the endpoint.
This flag overrides the project's configuration file.
See --fork-url.
--initial-balance <BALANCE>
The initial balance of deployed test contracts
--sender <ADDRESS>
The address which will be executing tests/scripts
--ffi
Enable the FFI cheatcode
--always-use-create-2-factory
Use the create 2 factory in all cases including tests and
non-broadcasting scripts
--create2-deployer <ADDRESS>
The CREATE2 deployer address to use, this will override the one in the
config
Fork config:
--compute-units-per-second <CUPS>
Sets the number of assumed available compute units per second for this

--no-rpc-rate-limit
Disables rate limiting for this node's provider.
See also --fork-url and

The timestamp of the block
--block-number <BLOCK>
The block number
--block-difficulty <DIFFICULTY>

--block-gas-limit <GAS_LIMIT>

[aliases: gas-limit]
--memory-limit <MEMORY_LIMIT>
The memory limit per EVM execution in bytes. If this limit is
exceeded, a `MemoryLimitOOG` result is thrown.
The default is 128MiB.
--disable-block-gas-limit
Whether to disable the block gas limit checks
[aliases: no-gas-limit]
--isolate
Whether to enable isolation of calls. In isolation mode all top-level
calls are executed as a separate transaction in a separate EVM
context, enabling more precise gas accounting and transaction state
changes
--odyssey
Whether to enable Odyssey features
Display options:
--color <COLOR>
The color of the log messages
Possible values:
- auto: Intelligently guess whether to use color output (default)
- always: Force color output
- never: Force disable color output
--json
Format log messages as JSON
-q, --quiet
Do not print log messages
-v, --verbosity...
Verbosity level of the log messages.
Pass multiple times to increase the verbosity (e.g. -v, -vv, -vvv).
Depending on the context the verbosity levels have different meanings.
For example, the verbosity levels of the EVM are:
- 2 (-vv): Print logs for all tests.
- 3 (-vvv): Print execution traces for failing tests.
- 4 (-vvvv): Print execution traces for all tests, and setup traces
for failing tests.
- 5 (-vvvvv): Print execution and setup traces for all tests,
including storage changes.
