We are pleased to introduce you the new version of <m:name/>. |
| 250 | 12 |
This release brings Guile support and some minor changes: |
| 241 | 13 |
</p> |
14 |
||
15 |
<ul> |
|
16 |
<li> |
|
| 250 | 17 |
<strong>Guile transformations</strong>: |
18 |
the new tool <code>relpipe-tr-guile</code> integrates GNU Guile |
|
19 |
and allows writing filters (WHERE-like conditions) and transformations (SELECT-like projections) |
|
20 |
in the Scheme language. |
|
21 |
Filter could look like e.g. <code>--where '(or (= $size 666) (= $size 1984) )'</code>. |
|
22 |
See the <m:a href="examples">examples</m:a> page for details. |
|
| 241 | 23 |
</li> |
24 |
||
25 |
<li> |
|
| 250 | 26 |
<strong>ODS output</strong>: |
27 |
Integer attributes are now generated with proper data type, |
|
28 |
so e.g. in LibreOffice they are recognized as numbers instead of strings. |
|
29 |
</li> |
|
30 |
||
31 |
<li> |
|
32 |
<strong>CSV output</strong>: |
|
33 |
Now generates CRLF line-ends (as defined in RFC 4180). |
|
| 241 | 34 |
</li> |
35 |
||
36 |
<li> |
|
| 250 | 37 |
<strong>Filesystem input</strong>: |
38 |
Now allows custom relation names (option: <code>--relation</code>). |
|
39 |
And default xattr namespace is now <code>user</code> so the attribute names do not have to be prefixed with <code>user.</code>. |
|
| 241 | 40 |
</li> |
41 |
</ul> |
|
| 250 | 42 |

Instalation was tested on Debian GNU/Linux 9.6. |
83 |
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). |
|
90 |
Tools <code>out-gui.qt</code> and <code>tr-python</code> require additional libraries and are not built by default. |
|
91 |
</p> |
|
| 151 | 92 |
|
| 241 | 93 |
<p> |
94 |
The module <code>relpipe-in-filesystem</code> uses C++ filesystem API which is supported since GCC 8. |
|
95 |
This module can be compiled and seems usable even with GCC 6, but requires some patching (switch to the experimental API): |
|
96 |
</p> |

The module <code>relpipe-tr-guile</code> uses GNU Guile 2.2 but can also work with 2.0. |
|
104 |
In such case, it requires this patch: |
