GCLI aims to make scripting with Groovy easier by providing opinionated utilities related to common concerns like logging or database accesses.
Requirements
Any script that uses gcli must use Java 8 or later and Groovy 2.5 or later.
Use it !
Here is a sample script that makes use of logging and database access capabilities :
#!/usr/bin/env groovy
import fr.marcwrobel.gcli.ScriptCliTexts
import groovy.sql.Sql
import groovy.util.logging.Slf4j
@Grab(group = 'fr.marcwrobel', module = 'gcli', version = '0.0.5')
@Grab(group = 'ch.qos.logback', module = 'logback-classic', version = '1.2.3')
@GrabConfig(systemClassLoader = true)
@Grab(group = 'org.postgresql', module = 'postgresql', version = '42.2.20')
final class CommandConfiguration extends DatabaseConfiguration {
CommandConfiguration(Class<?> scriptClass) {
super(new ScriptCliTexts(scriptClass))
}
}
@Slf4j
class Command {
private final CommandConfiguration config
Command(CommandConfiguration config) {
this.config = config
}
int execute() {
try {
config.withSql { Sql sql ->
// do something
return 0
}
} catch (Exception e) {
log.error('Command failed : {}', e.message, e)
throw e
}
log.info('Command succeeded.')
return 0
}
}
CommandConfiguration config = new CommandConfiguration(this.class)
if (!config.parse(args)) {
System.exit(1)
} else if (config.showHelp) {
config.usage()
System.exit(0)
}
System.exit(new Command(config).execute())
