Why is < Escaping to < in My Template?

Unexpected HTML Escaping in Templates

In certain template scenarios, developers may encounter an issue where < characters are being unnecessarily escaped to <, while > characters remain untouched. This behavior can be puzzling, especially when trying to insert values like into a template.

Explanation

The reason for this escaping lies in the underlying library used for template processing. html/template is designed to generate HTML output and provides automatic escaping for potential code injection vulnerabilities. It interprets < and > as HTML entities to prevent malicious code from being executed.

Unfortunately, this escaping is context-specific and only applies to HTML contexts. Since the provided template is not intended to generate HTML, the escape process should not occur.

Resolution

To resolve this issue, consider using text/template instead of html/template for generating files like readmes and licenses. text/template does not perform the HTML-specific escaping, allowing characters like < to remain in their original form. By switching to this library, the expected output of should be achieved.
