Introduction ↟

This project is mostly a wrapper around the Erlang/OTP mnesia and qlc modules. That being said, it does provide the additional following benefits:

• functions and macros for easily creating tables
• additional convenience functions
• Lisp-friendly wrapper functions for Mnesia functions (i.e., hyphens!)

Documentation ↟

Documentation for Moneta is available in the following forms:

• Moneta Tutorial

Modules ↟

The Erlang namespaces for the modules (ab)used by this project are the following:

• mnesia
• qlc

These are accessible via those same module names in LFE, or using this library, from the following:

• mnta - holds alll the mnesia functions besides the dirty ones
• mnta-drty - split dirty functions into their own module ("dirty" operations are short-cuts that bypass much of the processing and increase the speed of the transaction)
• mnta-qry - qlc alias; longer to type than qlc, but provides some nice visual context when scanning code

Function names in the mnta* modules have the Erlang underscores replaced with LFE hyphens. This work is done via the LFE kla library.

Resources ↟
