This is about the speedata Publisher. Room language is English (and perhaps German)
als LaTeX-Fan habe ich speedata entdeckt, und ich bin nach einigen kurzen Versuchen begeistert. Aber leider ist sogleich eine erste Frage aufgetreten, die ich im Handbuch nicht erklärt fand.
Es gibt die Funktion sd:format-string, die mit den printf-Formatierungen kompatibel ist. Ich möchte damit nun Euro-Beträge formatieren.
<Value select="sd:format-string(Betrag,'%.2f' €)"/>Leider erhalte ich als Dezimaltrenner immer den Punkt. Wenn ich die deutsche Schreibweise mit Komma wollte, müsste ich z. B. an LuaTeX
setlocale("de_DE") übergeben. Wie mache ich das in speedata?
sd:format-number(), mit der Zahlen formatiert werden können. Hilft das? (https://doc.speedata.de/publisher/de/xpathfunktionen/)
Naja, damit kann ich gerade noch so leben.
Auch eine Locale-Abhängigkeit haben die Datumsfunktionen aus Lua (os.date). Ist daran gedacht, diese (zumindest in der engl. Variante) mit den entsprechenden Formatierungsparametern zu unterstützen?
Noch eine andere Frage: Im Beispiel „runningsum“ ist die Ausgabe einer Summe in der Fußzeile einer Tabelle beschrieben. Die fertigen Summen werden aber alle direkt aus der Datei data.xml geholt. Gibt es eine einfache Möglichkeit, die Summe direkt im zu erstellenden Dokument zu berechnen?
@jorg.l_gitlab Ich habe derzeit keine Pläne, os.date etc. zu unterstützten. Eher das, was es bei XPath in dieser Richtung gibt, wobei ich gerade da keinen Überblick habe.
Zu runningsum: klar, kann man die Daten auch dynamisch berechnen. Du musst nur die Variable _last_tr_data zu jeder Zeile neu setzen.
<SavePages> to create virtual pages. You can count them with sd:count-saved-pages and write Page X of Y on the virtual pages before putting them in your final pdf with <InsertPages>.
Thanks, that works, sorry I missed it.
On another topic, is there any way to deal with situations like the below one?
I've been searching around but can't find any starting point at least.
<para>
Please refer to the <link address="page12">Chapter 1</link> for a brief history of the <tool>hammer</tool> and more details about its usage.
</para>
As you can see <para> element has also text and XML child elements alternating.
For the <link> I would like to create a link using <A>
For the <tool> I would like to create a marker.
Is there any way to achieve this in speedata?
<data>
<para>
<val>Please refer to the </val>
<link address="page12">Chapter 1</link>
<val>for a brief history of the </val>
<tool>hammer</tool>
<val>and more details about its usage. </val>
</para>
</data>@pgundlach That sounds quite complex, these were just some examples, but there are many many more situations, this would mean we should create a pre-processing program to adjust the XML to these requirements.
Something else I noticed, regarding the internal links to a PDF page, the attribute "link" of the <A> element can only be text.
It would be better if this attribute would allow X-path expressions. Because at the moment the link destination has to be hardcoded in the layout. In many cases you can generate the link and the destination with variables.
@MihailCosmin For the first issue: I usually use a preprocessing stage when I get input from some source that I can't control. The publisher comes with Saxon 9 and you can call it with the lua script.
The second issue is quite easy to solve: include your xpath into curly braces, such as link="{ xpath expression }"

@MihailCosmin Good question. Depending on how you output paragraphs / text it could be possible now...
If you output a paragraph one by one with PlaceObject or Output, you can ask for the current frame and line number and draw the rules yourself. If you place multiple objects in one go, you are out of luck in the current version.
This worked well for text paragraphs, but for table rows it won't work, right? For each row I get the row the whole table was output.
I think this is what you meant with "If you place multiple objects in one go, you are out of luck in the current version."
Will there be a solution in the next version?
Found a workaround for the moment. Works quite well.
For each table row I add first an extra <td> with no borders that has and empty paragraph.
I check if the row (from the data) should have a change bar, then output the extra <td> with a border on the left side.
The change bar is a bit more inside the page than the text ones, but it's satisfactory for now.
I think there is an issue with the hyphenate attribute of the DefineTextFormat.
I have it set to hyphenate ="no", yet wherever I have text like "20-12-2019" it can happen that I have 20- on one line and the rest -12-2019 on the next line.
I have also tried to set hyphenate ="yes" and hyphenchar ="ß" yet it keeps splitting anywhere I have dashes.
Is there anyway I can set it up so it won't split where I have dashes in different rows?
@EmmanuelOga The data XML is processed while executing the layout.xml file. You could preprocess the data file if you want (that is why saxon is part of the distribution)
The logic in the layout file is a mixture of XSLT and HTML, so not directly comparable. I assume you have found the hello world example in the manual? https://doc.speedata.de/publisher/en/helloworld/#ch-helloworld
