Download Langchain Documentation

[Moturu-Sumanth]

I want to download the langchain documentation because of the rate at which it is updating. Some of the functions I used earlier are no longer visible in the documentation and it is very difficult for me to maintain the code for the applications that I develop and integrate some new functionalities to it. Is there any way I can download a pdf version of the documentation and save it for a version of langchain or have the documentation available for the previous versions.

Hi @Moturu-Sumanth, apologies for only getting to this question now and thanks for asking it.

The API reference docs are hosted on ReadTheDocs which should allow PDF downloads once #16550 lands and builds. They also maintain multiple versions, which you can explore in the flyout in the bottom right.

The main docs do not natively support PDF downloads, but there are some open source projects which I believe should let you download a Docusaurus site as a pdf: docs-to-pdf (cc @jean-humann) and docusaurus-prince-pdf (cc @sparanoid) are the two I've seen.

Now that we have long-term support of certain package versions (e.g. langchain 0.1 will continue to be patched even after langchain 0.2 is released) we're planning on explicitly versioning the main docs. This will start with the langchain 0.2 release.

We also want to be better about documentation stability. If there are any specific methods/classes/etc. that are no longer documented but you're still using, we'd love to know about!

@baskaryan it seems that the option (pdf off readthedocs is not working), see #19484

The documentation is on the GitHub repo. We could git checkout the last commit before the specific date whose documentation we want to see
