# Hello, world!

The classic: “Hello, world!” Or: what does a simple document look like? As already described, the input for the Publisher consists of two files: the data file and the layout file. Both must be in XML format and must always be available. The data file is saved under the name `data.xml` and the layout file under `layout.xml`. These two files are best created with an XML editor or with the free text editor Visual Studio Code which has very good XML support.

| If you want to try the “Hello World” example yourself, you can simply call `sp new helloworld`. This creates a directory with the two necessary files. So you can start immediately and create a PDF in this directory with the `sp` command.

The data file for the “Hello World” example is named `data.xml`:

    <data>Hello world!</data>

That is enough for the simple example. The layout file is a bit more extensive (save as `layout.xml`):

    <Layout
      xmlns="urn:speedata.de:2009/publisher/en"
      xmlns:sd="urn:speedata:2009/publisher/functions/en">

      <Record element="data">
        <PlaceObject>
          <Textblock>
            <Paragraph>
              <Value select="."/>
            </Paragraph>
          </Textblock>
        </PlaceObject>
      </Record>
    </Layout>

These two files are stored in an otherwise empty directory. On the command line, change to this directory (with `cd <directory name>`) and call the Publisher with the command

    $ sp

on. The `$` character is intended to represent the prompt and is not entered. If everything goes smoothly, the result is a PDF file named `publisher.pdf` in the same directory.

| For Windows users: if the publisher cannot create the PDF, this is sometimes because the same file is still open in a window. This can be Adobe Reader, but also Windows Explorer.

## The “Hello World!” example explained

Here follows a short explanation of the two files. The data file can be structured as you wish, as long as the content is well-formed XML (see glossary).

    <data>Hello world!</data>

The layout file is a bit more complicated, at least at first sight.

    <Layout  ①
      xmlns="urn:speedata.de:2009/publisher/en"
      xmlns:sd="urn:speedata:2009/publisher/functions/en">

      <Record element="data">  ②
        <PlaceObject>  ③
          <Textblock>
            <Paragraph>
              <Value select="."/> ④
            </Paragraph>
          </Textblock>
        </PlaceObject>
      </Record>
    </Layout>

① The root element is called `Layout` and has the namespace `urn:speedata.de:2009/publisher/en`. The second namespace is necessary for the built-in functions, but is not used in the example. (Tip: nevertheless always specify it in the layout, so that there are no surprises later).

② Here the data processing starts. The root element of the data file is specified in the attribute `element`.

③ `<PlaceObject>` is the command to output things (texts, images, boxes, …​) into the PDF.

④ The dot at the select attribute means “the current element”, in this case the root element. The text value of the element is output here, i.e. the string `Hello world!`

We will not discuss more at this point. Rather, there is a reference to the corresponding chapters in this manual: Under File organization is described how the data file and the layout file are to be structured, and under Outputting objects the command `<PlaceObject>` is described.
