We are pleased to introduce you the new development version of <m:name/>. |
12 |
This release brings Recfile input and output and ASN.1 BER output: |

<strong>Recfile format support</strong>: |
18 |
Recfile is the native format of <a href="https://www.gnu.org/software/recutils/">GNU Recutils</a>. |
|
19 |
Recfiles are text files that contain records of various types. |
|
20 |
They are human-editable and serve as simple databases. |
|
21 |
<m:name/> now contain tools for converting relational data streams to and from the recfile format. |
|
22 |
This format is good for editing by hand or for storing in some version control system. |
|
23 |
GNU Recutils and <m:name/> can be used together for data processing or e.g. for data-driven scripting. |
|
| 250 | 24 |

25 |

26 |

|

<strong>ASN.1 BER output</strong>: |
28 |
Abstract Syntax Notation One (ASN.1) is traditional and well established language for describing interfaces and data structures in particular. |
|
29 |
This format/language is widespread and actively used in telecommunications, cryptography and other industries. |
|
30 |
<abbr title="Basic Encoding Rules">BER</abbr> is one of ASN.1 encodings. |
|
31 |
This release of <m:name/> bring <abbr title="This support will be further improved and extended in further releases.">basic</abbr> support for output in the BER format. |
|
32 |
Now it can serve as a preview (such data can be opened in dumpasn1 or wireshark) or a template (the source code can be modified to generate BER data in some particular format) |
|
33 |
and help with interaction with ASN.1 <em>native speakers</em>. |
|
| 241 | 34 |

Please note that this is still a development relasease and thus the API (libraries, CLI arguments, formats) might and will change. |
|

Instalation was tested on Debian GNU/Linux 9.6. |
84 |
The process should be similar on other distributions. |

<m:name/> are modular thus you can download and install only parts you need (the libraries are needed always). |
|
91 |
Tools <code>out-gui.qt</code> and <code>tr-python</code> require additional libraries and are not built by default. |
|

|
| 151 | 93 |
|
| 241 | 94 |
<p> |
95 |
The module <code>relpipe-in-filesystem</code> uses C++ filesystem API which is supported since GCC 8. |
|
96 |
This module can be compiled and seems usable even with GCC 6, but requires some patching (switch to the experimental API): |
|
97 |

The module <code>relpipe-tr-guile</code> uses GNU Guile 2.2 but can also work with 2.0. |
|
105 |
In such case, it requires this patch: |
|
