GNU Recutils

 [GNU Recutils logo]

GNU Recutils is a set of tools and libraries to access human-editable, plain text databases called recfiles.

The picture below shows a sample database containing information about GNU packages, along with the main features provided by recutils.

  • Mandatory and forbidden fields.
  • Unique fields and primary keys.
  • Auto-counters and time-stamps.
  • Arbitrary constraints.
Rich Type System for Fields

Encryption Support
  • Selective: individual fields can be encrypted.
