示例1: printTailAndWatchFile
async function printTailAndWatchFile(file:any, tailSize:number) {
if (await qfs.exists(file)) {
const content = await qfs.read(file)
const lines = content.split('\n')
const from = Math.max(0, lines.length - tailSize)
const lastLines = lines.slice(from).join('\n')
console.log(lastLines)
}
watchFile(file)
}示例2: async
getHomeParams: async (isMemory:boolean, theHome:string) => {
const params:any = await dir.getHomeFS(isMemory, theHome)
const home = params.home;
if (isMemory) {
params.dbf = () => new SQLiteDriver(':memory:');
params.wotb = WoTBObject.memoryInstance();
} else {
const sqlitePath = path.join(home, dir.DUNITER_DB_NAME + '.db');
params.dbf = () => new SQLiteDriver(sqlitePath);
const wotbFilePath = path.join(home, dir.WOTB_FILE);
let existsFile = await qfs.exists(wotbFilePath)
if (!existsFile) {
