|
11 We are pleased to introduce you the new version of <m:name/>. |
|
12 This release brings Guile support and some minor changes: |
|
13 </p> |
|
14 |
|
15 <ul> |
|
16 <li> |
|
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. |
|
23 </li> |
|
24 |
|
25 <li> |
|
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). |
|
34 </li> |
|
35 |
|
36 <li> |
|
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>. |
|
40 </li> |
|
41 </ul> |
|

81 <p> |
|
82 Instalation was tested on Debian GNU/Linux 9.6. |
|
83 The process should be similar on other distributions. |

|
88 <p> |
|
89 <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> |
|
92 |
|
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): |
|

|
102 <p> |
|
103 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: |
