Simple Components v4.20 released

Changes to the previous version:
  • Modbus TCP client bug fixed. The bug prevented receiving large responses, more than 60 words, e.g. to FC3 (read holding registers).

Deepend v3.9 Released

Deepend is a set of storage pools for Ada 95, Ada 2005, and Ada 2012 that includes subpool capabilities. Groups of memory allocations from a storage pool can be assigned to specific subpools where groups of objects can be deallocated as a group by deallocating the subpool, rather than by individual deallocations of objects.

Each subpool is "owned" by a specific task in Ada, allowing allocations and deallocations to be efficient, as well as being safer and less error prone.

Since version 3.4, the most notable changes are:
  • Ada 2012 subpools were not working in version 3.4, but now work properly with the Ada 2012 subpool syntax.
  • It is now possible to set task ownership of the storage pool itself, as well as subpools.
  • Portability changes made to integrate with PTC's ObjectAda 64bit compiler for Ada 2005 and Ada 95
  • Portability changes made to integrate with RR Software's Janus Ada compiler for Ada 95
  • Memory allocations returned by the generic allocators were not initializing memory. This is important for types that have discriminants or tags. Now memory is initialised which is consistent with behaviour when one uses Ada's "new" keyword syntax to provide the allocations.
  • The generic allocator routines now support allocating unconstrained types, such as strings.

There are 4 different storage pools to choose from;
  • Unbounded storage pool with subpool support
  • Bounded storage pool with subpool support
  • Unbounded storage pool without subpool support
  • Bounded storage pool without subpool support

ZanyBlue - 1.3.0b released

The changes since the last release are:
  • Added a new utility zbinfo to query built-in data. This was released as an example previously (the dumplocale example which has been dropped).
  • Added encoding support to convert Wide_String values to String based on an encoding schema, e.g., UTF-8, ISO8859-2, CP932, SHIFT_JIS, etc. To fully use this functionality, narrow accessors should be used which, when printing, use Stream_IO to avoid interaction between the Text_IO and encoded values. The list of supported encodings is available via zbinfo --list-encodings.
  • The default locale is now en_US.UTF-8 if no other locale can be determined from the environment.
  • Updated the documentation (and website) to use the Sphinx documentation system.
  • Updated and expanded the documentation. Additional documentation is, however, needed. Switch to gnatdoc from gnathtml to generate the source code based documentation.
  • Restricted the usage of the -gnatW8 compilation option to just the source files containing UTF-8 encoded strings: the message pool file generated by the zbmcompile utility.
  • Added option to the zbmcompile utility to generate ASCII only source files (-A option).
  • Added option to the zbmcompile utility to define handling of non-Ada message keys when generating accessors (the -X option).
  • Updated the build to use gprbuild instead of gnatmake.
  • Updated the build to use -gnat2012 in all gpr files.
  • Switched from AUnit to Ahven for unit testing.
  • Minor source code changes based on stricter checks with GNAT 2016.

Thick bindings for Zstd v0.8 released

I created a set of thick bindings against the recent v0.8.0 version. Those cover the stable API (basic compression / decompression and use of dictionaries). The API for streaming compression / decompression is not yet stable, and as such it is only available in the static library. Once streaming de/compression is provided in the shared library,

Ada/SPARK ASN.1 implementation version 0.0.01

I'm making public my ASN.1 project which aims to be a verified implementation of ASN.1, which is used in security-certificates, which is hopefully the first step in a verified-TLS/-TLS -- the project also aims to be [directly] usable in DSA projects.

As of 0.0.01 the only portion implemented is a pure big-number package, and another currently shared-passive unit for usability.
I would certainly appropriate comments, criticism, and most especially contributions.

Thick bindings for libsodium

These bindings are thick and I've committed the testcases I was using to serve as examples. They cover the most of the functionality of libsodium, but some are missing the thick counterparts (e.g. most of the detached versions have no thick counterpart as I stuck with the recommended "combined" variants).

Adequate, MQTT broker and client programs based on Kasakov's Components

The Adequate project provides command line clients for the MQTT protocol. All the hard work is provided by Dmitry Kazakov's Components.
Among them is an implementation of the MQTT protocol.

The Adequate project consists of three programs
  1. aq_broker, a MQTT broker or MQTT server.
  2. aq_pub, a MQTT client for publishing single messages with a command line interface.
  3. aq_sub, a MQTT client for subscribing to a topic (including wildcards). It also only has a command line interface.

Dequesterity v1.5 released

(Buffers of many shapes and sizes)

Dequesterity is a set of Ada 2005 generics that provide various forms of general purpose buffer containers.

ZanyBlue v1.2.1 Beta Available

This is an Ada library currently targeting localization support for Ada (along the lines of Java properties) with supporting message formatting and built-in localization for about 20 locales.

The properties files are compiled into Ada sources built with your application and use to access application messages at run-time.

The run-time locale is used to select localized messages, if they are available.
