[astro-fuse] End Of The Stream Or A Document Separator Is Expecte
Astro-Fuse: End of the Stream or a Document Separator is Expected
Astro-Fuse is a powerful tool for indexing and searching content in Astro projects. However, users have reported issues with indexing Markdown files that contain source code. In this article, we will explore the issue and provide a solution to bypass the problem.
When using Astro-Fuse to index Markdown files that contain source code, users may encounter an error message indicating that the end of the stream or a document separator is expected. This error occurs when the Astro-Fuse parser encounters a source code block in the Markdown file and fails to parse it correctly.
To illustrate the issue, let's consider an example Markdown file (TS17009.md) that contains source code:
## TS17009
> 'super' must be called before accessing 'this' in the constructor of a derived class.
### Broken Code ❌
```ts
abstract class Animal {
abstract name: string;
}
class Dog extends Animal {
public name;
constructor(name: string) {
this.name = name;
super();
}
}
**Configuring Astro-Fuse**
==========================
To index the Markdown file, we need to configure Astro-Fuse to extract the content from the file. In this case, we can use the following configuration:
```ts
fuse(['frontmatter.title', 'frontmatter.description', 'frontmatter.tags'], {
basedOn: 'source',
})
```
However, when we run Astro-Fuse with this configuration, we encounter the error message:
```bash
[astro-fuse] end of the stream or a document separator is expected (2:16)
1 | abstract class Animal {
2 | abstract name: string;
--------------------^
3 | }
4 |
```
**Workaround**
=============
To bypass the issue, we can modify the Astro-Fuse configuration to extract the content from HTML files instead of raw Markdown files. We can do this by changing the `basedOn` option to `output` and setting `extractContentFromHTML` to `main`. Additionally, we can add a filter to exclude certain paths:
```ts
fuse(['frontmatter.title', 'frontmatter.description', 'frontmatter.tags'], {
basedOn: 'output',
extractContentFromHTML: 'main',
filter: (pathName) => {
const isBlog = pathName.startsWith('/blog/');
const isCategory = pathName.startsWith('/category/');
const isTag = pathName.startsWith('/tag/');
return !isBlog && !isCategory && !isTag;
},
})
```
**Conclusion**
=============
In conclusion, the issue with Astro-Fuse indexing Markdown files that contain source code is a known problem. However, by modifying the Astro-Fuse configuration to extract content from HTML files, we can bypass the issue and continue indexing our content. We hope that this workaround will be helpful to users who encounter this problem.
**Future Improvements**
=====================
We hope that the Astro-Fuse team will address this issue in future releases and provide a more robust solution for indexing Markdown files that contain source code. In the meantime, we recommend using the workaround described above to continue indexing your content.

**Astro-Fuse: End of the Stream or a Document Separator is Expected - Q&A**
**Introduction**
===============
In our previous article, we explored the issue with Astro-Fuse indexing Markdown files that contain source code. We also provided a workaround to bypass the problem by modifying the Astro-Fuse configuration to extract content from HTML files. In this article, we will answer some frequently asked questions (FAQs) related to this issue.
**Q: What is the cause of the "end of the stream or a document separator is expected" error?**
=====================================================
A: The error occurs when Astro-Fuse encounters a source code block in the Markdown file and fails to parse it correctly. This is because Astro-Fuse is designed to parse HTML files, not Markdown files with source code.
**Q: Why does the error occur only when indexing Markdown files with source code?**
=====================================================
A: The error occurs only when indexing Markdown files with source code because Astro-Fuse is not designed to handle source code blocks in Markdown files. When it encounters a source code block, it fails to parse it correctly and throws the error.
**Q: Can I use Astro-Fuse to index Markdown files with source code without any issues?**
=====================================================
A: Unfortunately, no. Astro-Fuse is not designed to handle Markdown files with source code, and it will throw the error when it encounters a source code block.
**Q: What are the alternatives to Astro-Fuse for indexing Markdown files with source code?**
=====================================================
A: There are several alternatives to Astro-Fuse that can handle Markdown files with source code, such as:
* **Fuse.js**: A JavaScript library for indexing and searching content. It can handle Markdown files with source code.
* **lunr.js**: A JavaScript library for indexing and searching content. It can handle Markdown files with source code.
* **Algolia**: A search engine that can handle Markdown files with source code.
**Q: Can I use the workaround provided in the previous article to index all my Markdown files?**
=====================================================
A: Yes, you can use the workaround provided in the previous article to index all your Markdown files. However, keep in mind that this workaround will only work if you have modified the Astro-Fuse configuration to extract content from HTML files.
**Q: Will the Astro-Fuse team address this issue in future releases?**
=====================================================
A: We hope that the Astro-Fuse team will address this issue in future releases. However, we cannot guarantee that they will do so.
**Q: Can I contribute to the Astro-Fuse project to help fix this issue?**
