Access to Sphinx AST before transforms/post-transforms

[Matt McKay]

Hi Sphinx Group. 

Is there a way to access the Sphinx abstract syntax tree (AST) before any transforms or post-transforms are applied (i.e. directly after the parser phase)?

I am writing an extension to convert reST to Myst syntax but I am finding restoring some of the information contained in the original rst file difficult to recover. The key example is a `toctree` that uses the `:hidden:` option appears to be dropped from the AST here (https://github.com/sphinx-doc/sphinx/blob/e4a55cb76f7f45e74997017b8fa4ca913d0ac602/sphinx/environment/adapters/toctree.py#L65)

Any tips / hints would be great -- thanks for your time. 

Cheers,

Matt

Hi,

How about using a transform having a very high priority? Then you can
access a doctree (a.k.a. AST) just after the parsed.

Thanks,
Takeshi KOMIYA

Thanks Takeshi -- that is a nice idea. I will give that a shot.
