Console

Create class based commands with Yargs using decorators.

index.ts

import yargs from 'yargs';
import {enableYargsClassCommands, addCommandDirs} from '@radic/console'

addCommandDirs(
    ['path/*/to/*/somewhere', 'another/**/path'], // glob patterns to command directories
    ['.js','.ts','!.d.ts'] // allow .js and .ts. Ignore .d.ts files
);

enableYargsClassCommands(yargs);

yargs.help('h')
     .alias('h', 'help')
     .showHelpOnFail(true);

const args = yargs.parse();

if ( args[ 'help' ] ) {
    yargs.showHelp();
}
