The built-in <code>CONCATENATE</code> function accepts only single cells as arguments but not a range of cells. This has always bugged me. To concatenate a range of cells you must create a macro, which does the work for you. Afterwards you can use the function across your document. <a href="http://www.pitonyak.org/">Andrew Pitonyak</a> has written a nice and profound <a href="http://www.pitonyak.org/oo.php">macro documentation</a> for OpenOffice, which is available as <a href="http://www.hentzenwerke.com/catalog/oome.htm">book</a> too. These docs will also work for LibreOffice. Likewise, the <a href="http://www.libreoffice.org/get-help/documentation/">official documentation</a> is a good starting point.</p> <p>To create custom macros you need to open a document and execute <code>Tool &gt; Macros &gt; Organize Macros &gt; LibreOffice Basic</code> from the application menu. Select your document, create a new module and paste the snippet. Save the document and close the window. Now you can use <code>=MyConcat($A1:$A99, "; ")</code> or <code>=MyConcat($A1:$F1)</code> to concatenate a range of cells.</p> <!-- highlight: lang-basic --> <div class="codehilite"><pre><span></span><span class="n">REM</span> <span class="o">*****</span> <span class="n">BASIC</span> <span class="o">*****</span> <span class="n">Sub</span> <span class="n">Main</span> <span class="k">End</span> <span class="n">Sub</span> <span class="k">Function</span> <span class="n">MyConcat</span><span class="p">(</span><span class="n">arr</span><span class="p">(),</span> <span class="n">Optional</span> <span class="n">sep</span> <span class="k">as</span> <span class="n">String</span><span class="p">)</span> <span class="k">as</span> <span class="n">String</span> <span class="n">Dim</span> <span class="n">i</span> <span class="k">as</span> <span class="n">String</span> <span class="n">Dim</span> <span class="n">r</span> <span class="k">as</span> <span class="n">String</span> <span class="n">Dim</span> <span class="n">s</span> <span class="k">as</span> <span class="n">String</span> <span class="k">If</span> <span class="k">Not</span> <span class="n">IsMissing</span> <span class="p">(</span><span class="n">sep</span><span class="p">)</span> <span class="k">Then</span> <span class="n">s</span> <span class="o">=</span> <span class="n">sep</span> <span class="k">Else</span> <span class="n">s</span> <span class="o">=</span> <span class="ss">&quot;, &quot;</span> <span class="n">EndIf</span> <span class="n">r</span> <span class="o">=</span> <span class="ss">&quot;&quot;</span> <span class="k">For</span> <span class="k">Each</span> <span class="n">i</span> <span class="k">In</span> <span class="n">arr</span><span class="p">()</span> <span class="k">If</span> <span class="n">i</span> <span class="o">&lt;&gt;</span> <span class="ss">&quot;&quot;</span> <span class="k">Then</span> <span class="n">r</span> <span class="o">=</span> <span class="n">r</span> <span class="o">&amp;</span> <span class="n">i</span> <span class="o">&amp;</span> <span class="n">s</span> <span class="n">EndIf</span> <span class="k">Next</span> <span class="n">i</span> <span class="k">If</span> <span class="n">Len</span><span class="p">(</span><span class="n">r</span><span class="p">)</span> <span class="o">&gt;</span> <span class="n">Len</span><span class="p">(</span><span class="n">s</span><span class="p">)</span> <span class="k">Then</span> <span class="n">r</span> <span class="o">=</span> <span class="k">Left</span><span class="p">(</span><span class="n">r</span><span class="p">,</span> <span class="n">Len</span><span class="p">(</span><span class="n">r</span><span class="p">)</span><span class="o">-</span><span class="n">Len</span><span class="p">(</span><span class="n">s</span><span class="p">))</span> <span class="n">EndIf</span> <span class="n">MyConcat</span> <span class="o">=</span> <span class="n">r</span> <span class="k">End</span> <span class="k">Function</span> </pre></div> WRTNode Ausgepackt tag:christoph-polcin.com,2014-09-18:/2014/09/18/wrtnode-unboxing 2014-09-18T18:01:00Z Christoph https://christoph-polcin.com/ first-name@family-name.de <p>Endlich etwas Zeit gefunden, um den kleinen <a href="http://wrtnode.com/">WRTnode</a> zumindest einmal auszupacken.

März) kurz <a href="http://chemnitzer.linux-tage.de/2014/" title="Chemnitzer Linux-Tage">CLT</a>, feierten dieses Jahr ihren 16. Geburtstag und luden unter dem Motto <em>Vertrauen ist …?</em> herzlich ein.<br /> Neben einem beachtlichen <a href="http://chemnitzer.linux-tage.de/2014/de/vortraege/plan">Vortrags</a>- und <a href="http://chemnitzer.linux-tage.de/2014/de/vortraege/workshops">Workshop</a>-Programm gab es die Möglichkeit nette Leute aus der Linux &amp; Unix Gemeinschaft persönlich näher kennenzulernen. Allein letzteres ist bereits einen Besuch wert.</p> <p><a href="http://posativ.org/" title="Martin Zimmermann">Martin</a> und ich nutzten die <a href="http://chemnitzer.linux-tage.de/2014/" title="Chemnitzer Linux-Tage">CLT</a>, um unsere lieblings Linux Distribution <a href="http://gentoo.org/" title="gentoo linux">gentoo linux</a> zu präsentieren. Unsere Parole: <strong>Vertrauen ist gut, Kompilieren besser!</strong> Mit selbst gebackenen Keksen, Gummitieren, T-Shirts und Flyern standen wir Frage &amp; Antwort bereit.<br /> Unerwartet war die Nachfrage beachtlich groß. Vom <em>Erstkontakt mit gentoo</em> bis hin zu <em>konkreten Problemen</em> (bereits vor der offiziellen Eröffnung) war alles vertreten. Für den Großteil der Interessenten war <a href="http://gentoo.org/" title="gentoo linux">gentoo linux</a> ein Begriff. Nahezu alle hatten bereits mit <em>mehr oder weniger Erfolg</em> eine Installation absolviert. Anhand einer kleinen Umfrage stellte sich herraus, dass <a href="http://gentoo.org/" title="gentoo linux">gentoo linux</a> auf mehreren Geräten gleichzeitig und mehr als zufriedenstellend zum Einsatz kommt.</p> <p>Zu Demozwecken hatte ich mein <a href="http://cubieboard.org/tag/cubieboard2/">cubieboard2</a> mit dabei. Aufgrund mangelnder Zeit war es mit einem <a href="http://cubian.org/">cubian</a> bespielt und sollte zum <a href="http://chemnitzer.linux-tage.de/2014/" title="Chemnitzer Linux-Tage">CLT</a> ein frisches <a href="http://gentoo.org/" title="gentoo linux">gentoo linux</a> mit <a href="http://www.uclibc.org/" title="micro C-Standard-Bibliothek">uclibc</a> und <a href="http://de.wikipedia.org/wiki/Btrfs" title="B-tree FS">btrfs</a> Funktionalität erhalten.<br /> Der große Ansturm allerdings hielt mich von der notwendigen Konfiguration ab, sodass der <em>erste</em> Bootvorgang zum Sonntag Nachmittag erfolgte, aufgrund zweier Patzer jedoch auf Anhieb mißglückte: 1. fehlender btrfs Support im Kernel und 2. ein vom 3.4er Kernel nicht unterstütztes btrfs Feature (meinem Minimalismuswahn geschuldet).
