GNU recutils

GNU Recutils is a set of tools and libraries to access human-editable text-based databases called recfiles. A recfile contains data structured as a sequence of records. The rec format supports data integrity with the usage of record descriptors (keys, mandatory fields, field types, etc.) as well as the ability of record fields to refer to other records. Despite its simplicity, recfiles can be used to store medium-sized databases. The GNU recutils suite comprises a texinfo manual describing the Rec format, a C library (librec) providing a rich set of functions to access rec files, a set of C utilities that can be used in shell scripts and in the command line to operate on rec files, and an Emacs mode (rec-mode).

            Release Notes: A quite bad bug introduced in version 1.2 has been fixed. The bug was causing recins, recdel, and recset to report random integrity failures, due to an uninitialized variable. The %size special field was added, which allows you to define constraints in the size of the record sets. Translations updates were made. Many bugs were fixed.
