Introduction

When working with Pandoc and CSL stylesheets, you may encounter situations where you need to customize the appearance of your bibliographies. One common requirement is to adjust the entry-spacing, which is the distance between individual entries in the bibliography. In this article, we will explore how to change the entry-spacing to a specific value, such as 0.5, using the ieee-with-url CSL stylesheet.

Understanding CSL Stylesheets

CSL (Citation Style Language) stylesheets are used to format bibliographic citations and references. They are written in a specific XML-based language and can be customized to suit various citation styles. The ieee-with-url CSL stylesheet is a popular choice for formatting references in the IEEE style, which is commonly used in technical fields.

Modifying the ieee-with-url CSL Stylesheet

To change the entry-spacing in the ieee-with-url CSL stylesheet, you will need to edit the stylesheet file. You can download the ieee-with-url CSL stylesheet from the Zotero website: https://www.zotero.org/styles?q=ieee-with-url. Once you have downloaded the stylesheet, you can open it in a text editor and modify the relevant section.

Locating the Entry-Spacing Section

The entry-spacing section is located in the "bibliography" element of the CSL stylesheet. You can search for the term "entry-spacing" to locate the relevant section. In the ieee-with-url CSL stylesheet, the entry-spacing section is defined as follows:

<bibliography>
  <layout>
    <entry-spacing>0.5em</entry-spacing>
    <!-- other layout elements -->
  </layout>
  <!-- other bibliography elements -->
</bibliography>

Changing the Entry-Spacing Value

To change the entry-spacing value to 0.5, you can simply replace the existing value with the new value. In this case, you would replace 0.5em with 0.5em. However, since you want to change the value to 0.5, you can simply remove the em unit and replace it with the new value:

<bibliography>
  <layout>
    <entry-spacing>0.5</entry-spacing>
    <!-- other layout elements -->
  </layout>
  <!-- other bibliography elements -->
</bibliography>

Saving the Modified CSL Stylesheet

Once you have modified the entry-spacing section, you can save the modified CSL stylesheet file. Make sure to save the file with the same name and extension as the original file.

Using the Modified CSL Stylesheet with Pandoc

To use the modified CSL stylesheet with Pandoc, you will need to specify the new stylesheet file when running the pandoc command. You can do this by using the --csl option followed by the path to the modified CSL stylesheet file:

pandoc --from ... --csl=/path/to/modified/ieee-with-url.csl ... --citeproc

Example Use Case

Here is an example use case that demonstrates how to change the entry-spacing to 0.5 using the ieee-with-url CSL stylesheet:

pandoc --from markdown --csl=/path/to/modified/ieee-with-url.csl --citeproc example.md

In this example, we are using the pandoc command to convert a Markdown file to a PDF file. We are specifying the modified CSL stylesheet file using the --csl option, and we are using the --citeproc option to generate the bibliography.

Conclusion

In this article, we have explored how to change the entry-spacing to a specific value, such as 0.5, using the ieee-with-url CSL stylesheet. We have discussed the importance of understanding CSL stylesheets and how to modify them to suit your needs. We have also provided an example use case that demonstrates how to use the modified CSL stylesheet with Pandoc. By following the steps outlined in this article, you should be able to customize the appearance of your bibliographies and achieve the desired entry-spacing value.
