PrismJS: Yaml Rendering Indentation Issue
Introduction
PrismJS is a popular JavaScript library used for syntax highlighting and rendering code blocks in web applications. However, like any other software, it is not immune to bugs and issues. In this article, we will discuss a specific issue related to yaml rendering indentation in PrismJS.
Past Issues Searched
Before reporting this issue, we have thoroughly searched through open and closed issues to ensure that the bug has not yet been reported. This is essential to avoid duplicate reports and to ensure that the issue is properly documented.
Issue is a Bug Report
This is a bug report, and not a feature request or a support request. We will provide a detailed description of the issue, along with examples and expected behavior.
Describe the bug
When Prism is enabled, there are indentation issues on the first line of a yaml code block. This results in incorrect rendering of the code block. The issue is not present when there is a comment on the first line of the yaml code block.
Examples
Here are some examples to illustrate the issue:
Working example with a comment
# this is working
test:
a: 1
In this example, the yaml code block is rendered correctly with proper indentation.
Non-working example without a comment
test:
a: 1
In this example, the yaml code block is rendered incorrectly with missing indentation.
Expected behavior
When we write a yaml code block without a comment on the first line, we expect the code block to be rendered with proper indentation. The expected output is:
<div class="prism-codeblock ">
--
| <pre id="a5558bb" class="language-yaml ">
| <code>test:
| a: 1</code>
| </pre>
| </div>
However, the actual output is:
<div class="prism-codeblock ">
--
| <pre id="9d18c54" class="language-yaml ">
| <code>test:
| a: 1</code>
| </pre>
| </div>
As you can see, the indentation is missing in the actual output.

Conclusion
In conclusion, we have reported a bug related to yaml rendering indentation in PrismJS. The issue is not present when there is a comment on the first line of the yaml code block. We have provided examples and expected behavior to illustrate the issue. We hope that this report will help the PrismJS developers to identify and fix the issue.
Workaround
Until the issue is fixed, we can use a workaround to avoid the indentation issue. We can add a comment on the first line of the yaml code, like this:
# this is working
test:
a: 1
This will ensure that the yaml code block is rendered correctly with proper indentation.
Future Development
In the future, we hope that the PrismJS developers will fix this issue and provide a solution to avoid the indentation issue. This will make PrismJS a more reliable and robust library for syntax highlighting and rendering code blocks.
