NerveWallet based onNULS2.0Chain building toolschain-boxImplementation,nuls.ncfFor the core configuration file of the wallet, all modules can be configured in this file.
The configuration file format adopts a classwindowThe system configuration file structure is divided into groups and parameters.
[network] #group
port=18001 #parameterkeySum value
nuls.ncfThe content inside looks like this
[global]
encoding=UTF-8
language=en
...
[account]
keystoreFolder=/keystore/backup
[network]
port=10081
...
[global]It is a special group, and all modules will inherit the configuration items in this group. Global configuration can be configured under this group. [account]、[network]These two are proprietary configurations for the account module and network module. Name corresponding moduleModule.ncfInsideAPP_NAMEConfiguration items. When[global]When there are the same configuration items under the module group, the priority of the configuration under the module group is higher, coveringglobalThe configuration inside.
Within the module（such asModules/Nuls/account/1.0.0)Under the directory, there is aModule.ncfConfiguration file, externalnuls.ncfThe priority of is higher than that of the internal modulesModule.ncfWhen a configuration item with the same name appears,nuls.ncfThe configuration items in the module will overwrite the configuration items with the same name inside the module.
When downloading or packaging the wallet program for the first time, it does not existnuls.ncfThe first execution of this configuration filestartorstart-devWhen, it will be automatically generatednuls.ncf.
Wallet startup script, used in production environment to start wallet
./start
Wallet stop script, production environment uses this script to stop the wallet
./stop
start-upNervedevelopment environment(compatiblemacOSsystem)
./start-dev
ceaseNervedevelopment environment
./stop-dev
Start the command line to perform wallet operations.
./cmd
Specify the log level, the default log level isERROR,Optional log level:DEBUG、INFO、WARN、ERROR
./cmd -l DEBUG #Set the log level toDEBUG
Specify the configuration file path, the default configuration file is in the same directorynuls.ncf
./cmd -c /home/my.ncf
Check the startup status of the module. This function can quickly check whether each basic module has been successfully started. The script principle is to read the log flag bits in the log file.
./check-status
When I seeNULS WALLET IS RUNNINGWhen, it indicates successful startup.
Generate account address and private key. Not dependent on wallet, can run independently to generate addresses.
./create-address
