recutils 1.1 released

Item posted by Jose E. Marchesi <jemarch> on Thu 23 Dec 2010 11:41:10 PM UTC.

I am happy to announce a new release of the GNU recutils, version 1.1.

The user visible changes in this release are:

- New utility recfmt, to format records based on templates.

- Improvements in selection expressions:

  + Support ranges in field subscripts.
  + New date operators: before (<<), after (>>) and sametime (==).
  + New ternary conditional operator (?:).
  + New string concatenation operator (&).

- libcsv is now embedded in the source distribution, so it is no longer required to have it installed to build csv2rec.

- Portability problems fixed.  The programs have been tested in the following systems:

  + GNU/Linux
  + FreeBSD 6.4
  + MacOS X
  + mingw32
  + Solaris 8
  + AIX 5.1
  + HP-UX 11.00
  + IRIX 6.5
  + Tru64 (OSF/1 5.1)
  + Cygwin 1.7

- Lots of bug fixes.

The release can be found in the GNU ftp:

Alternatively, will automatically redirect to a nearby mirror.

                     About GNU recutils

GNU recutils is a set of tools and libraries to access human-editable, text-based databases called recfiles.  The data is stored as a sequence of records, each record containing an arbitrary number of named fields.  Advanced capabilities usually found in other data storage systems are supported by GNU recutils: data types, data integrity (keys, mandatory fields, etc) as well as the ability of records to refer to other records (sort of foreign keys).  Despite its simplicity, recfiles can be used to store medium-sized databases.

Please see the GNU recutils homepage for more information:

The GNU recutils suite comprises:

- A texinfo manual, describing the Rec format and the accompaying software.

- A C library (librec) that provides a rich set of functions to manipulate rec data.

- A set of C utilities that can be used in shell scripts and in the command line to operate on rec files:

  + `recinf' prints information about the contents of recfiles.
  + `recsel' prints records and field values.
  + `recins' adds new records to a recfile.
  + `recdel' deletes records.
  + `recset' manipulates fields.
  + `recfix' checks and fixes recfiles.
  + `recfmt' formats records based on templates.
  + `csv2rec' converts comma-separated-values files to recfiles.
  + `mdb2rec' converts mdb files (used by MS-Access) to recfiles.

- rec-mode.el - An emacs mode to edit and navigate recfiles. Still experimental.
