dcrctl
Dcrctl is a command-line client for interacting with the JSON-RPC servers of dcrd and dcrwallet.
Usage
In its default configuration, dcrctl connects to dcrd's mainnet RPC port on
localhost. The --wallet
and --testnet
flags change these defaults to the
dcrwallet RPC port and/or testnet ports. The --rpcserver/-s
flag can be used
to specify other hostnames or IP addresses of the server, and can also be used
to override the port defaults.
Dcrctl will attempt to read dcrd and dcrwallet config files for the user/password authentication. If these fields cannot be read, dcrctl must be manually configured with the correct authentication. Permanent configuration changes may be written to a config file in a platform-specific location:
- macOS:
~/Library/Application Support/Dcrctl/dcrctl.conf
- Windows:
%LOCALAPPDATA%\Dcrctl\dcrctl.conf
- Linux and other Unix:
~/.dcrctl/dcrctl.conf
Build and installation
-
Install Go 1.21 or higher version
Installation instructions can be found here: https://golang.org/doc/install. Ensure Go was installed properly and is a supported version:
$ go version $ go env GOROOT GOPATH
NOTE: if
GOROOT
andGOPATH
are initialized they must not be on the same path. It is recommended to add$GOPATH/bin
to yourPATH
according to the Golang.org instructions. -
Build or Update dcrctl
The latest release of dcrctl may be built in a single command without cloning this repository:
$ go install decred.org/dcrctl@release-v2.0.4
Using
@master
instead will perform a release build using the latest code from the master branch. This may be useful to execute RPC methods not yet found in the latest Decred release:$ go install decred.org/dcrctl@master
Alternatively, a development build can be performed by running
go install
in a locally checked-out repository.If you want to easily access
dcrctl
from the command-line without having to type the full path to the binary every time, ensure the bin directory rooted at the path reported bygo env GOPATH
is added to your system path:- macOS: how to add binary to your PATH
- Windows: how to add binary to your PATH
- Linux and other Unix: how to add binary to your PATH
Developing
When developing either the dcrd
or dcrwallet
RPC servers and making
modifications to the RPC methods, you may want to build a development version of
dcrctl
supporting these changes. Due to dcrctl
being built around
package-global method registrations and reflection, supporting these changes
only requires building with the updated packages.
This can be easily achieved by making use of a local Go workspace that uses the
development versions of dcrd
and dcrwallet
as follows:
$ go work init .
$ go work use ../dcrd/rpc/jsonrpc/types ../dcrwallet
