The gitbook importer had some issues while trying to ingest a particular
site, these commits allowed it to work as expected. The last commit
(06017ff) is to open the door to extending this class for other
documentation formats (which will come in a future PR).
First of all, big kudos on what you guys are doing, langchain is
enabling some really amazing usecases and I'm having lot's of fun
playing around with it. It's really cool how many data sources it
supports out of the box.
However, I noticed some limitations of the current `GitbookLoader` which
this PR adresses:
The main change is that I added an optional `base_url` arg to
`GitbookLoader`. This enables use cases where one wants to crawl docs
from a start page other than the index page, e.g., the following call
would scrape all pages that are reachable via nav bar links from
"https://docs.zenml.io/v/0.35.0":
```python
GitbookLoader(
web_page="https://docs.zenml.io/v/0.35.0",
load_all_paths=True,
base_url="https://docs.zenml.io",
)
```
Previously, this would fail because relative links would be of the form
`/v/0.35.0/...` and the full link URLs would become
`docs.zenml.io/v/0.35.0/v/0.35.0/...`.
I also fixed another issue of the `GitbookLoader` where the link URLs
were constructed incorrectly as `website//relative_url` if the provided
`web_page` had a trailing slash.
Added a GitBook document loader. It lets you both, (1) fetch text from
any single GitBook page, or (2) fetch all relative paths and return
their respective content in Documents.
I've modified the `scrape` method in the `WebBaseLoader` to accept
custom web paths if given, but happy to remove it and move that logic
into the `GitbookLoader` itself.
