the oraclize.it API has a few string related functions; the ether.camp IDE has a snippet called std.sol; I think the standard library should contain: the basic design patterns (owner only, mortal, etc.) interfaces for the Standardized Contract APIs; useful string helpers; support for bitwise operators until EVM and Solidity supports it natively

The oraclize-lib enables the use of the Provable engine capabilities also in a non-blockchain context, by providing an abstraction layer which resolves to Provable HTTP API. The oraclize-lib is currently in an experimental stage. ♦ Ethereum. The following section is dedicated to the Ethereum and Provable integration. Apr 08, 2020 · 💻See It In Action! For working examples of how to integrate the Provable API into your own smart-contracts, head on over to the Provable Ethereum Examples repository. Here you'll find various examples that use Provable to feed smart-contracts with data from a variety of external sources. Pastebin.com is the number one paste tool since 2002.

If you are currently using private chain, you need to use the Ethereum-Bridge API, which is a log listener listens to the oraclize query from private chain and connect to oraclize service. Caution! Please note that in order for the future timestamp to be accepted by Oraclize it must be within 60 days from the current time.
