for more desc see here

• requireFromParentUp(id: string, startModule?: NodeModule){:.language-ts} => parent-require
• requireFromTopParent(id: string, startModule?: NodeModule){.ts} => top-require
• getModuleByExports(exports) => which-module

diff

• support NodeJS.ErrnoException, Error object will has code='MODULE_NOT_FOUND' .
  so we can know when error happen is can't found module or it has other error
• split function, so u can custom it
