Hey @JarriqTheTechie 👋 Thank you for the PR 😄 For my understanding, this PR aims to enable the user to inject a Python function in a jinja template? |
Yes this is correct. Similar to how in flask there are functions such as url_for() This pr lays the foundation to seamlessly expose functions similar to those above in jinja. I actually put the PR together based on the url_for() enhancement that I saw in issues. |
|
@JarriqTheTechie , that is very smart!
One more question, is |
|
I copied the naming and signature from flask. |
|
Alright perfect @JarriqTheTechie . I will do a complete review tomorrow 😄 |

Hey @JarriqTheTechie 👋
Just two suggestions

- can you add docs for this function in
docs_srcfolder? Here
