# Overview
Adding conditional rendering logic to co-locate js and python documentation.
* `:::` conditional syntax can be used to switch between python only or js only content.
* Contains simple unit tests for `:::`
* PR adds set up for a way to implement a context switch between languages, but it will not be enabled until JS content is merged in.
* Contains a script that can add javascript documentation
Implementation of: https://github.com/langchain-ai/langgraph/pull/5118
## Example
Example of conditional rendering / compilation.
```markdown
### Config (static context)
Config is for immutable data like user metadata or API keys. Use
when you have values that don't change mid-run.
Specify configuration using a key called **"configurable"** which is reserved
for this purpose:
:::python
This content will only be rendered for the python site.
:::
:::js
this content will only be rendered for the js / ts site.
:::
```
This PR removes the following changes:
* notebooks that were converted to markdown
* mkdocs.yml file to reference the ipython notebooks rather than the
markdown files
* Makefile install vercel reverted
* hooks for markdown-exec
* notebook conversion jinja2 templates (for converting notebooks to
markdown exec format)
* Add ast parsing to determine whether we should include result="ansi".
It's not meant to be perfect, but will hopefully catch the most common
cases. Still requires manual review.
* Ideally we could suppress output in markdown-exec in the future.
* Add testing step to to docs build pipeline
* Requires updating import structure in some place
* Add simple unit test to cover some logic with highlights
