Syntax error reporting in Lookbook #593
Comments
Hey @Jackson200, so sorry for being so slow to reply and thanks for opening this as an issue. I totally agree that the behaviour you suggest is desirable, however it's actually a little tricky because of the way Lookbook finds and parses preview files. Because (unlike with vanilla ViewComponent previews) Lookbook pre-parses the Preview files to extract info from the comment annotations, any syntax errors actually mean that the parser often cannot correctly extract the data from that preview file. And without that data Lookbook can't display the preview or scenarios in the navigation, so it is never included in the list of 'known' previews, which is why you see the 'preview not found' 404 page instead. This is definitely not ideal! There are a number of ways this could be handled differently - certainly at a minimum parser errors could be surfaced in the UI somewhere, although in many cases it may still not be possible to avoid the preview being removed from the nav (and the associated 404 response). I'm not sure if that explaination makes much sense but this is definitely a feature request I'll keep open as I'm sure this is a pretty common pain point for people using Lookbook.
Thank you - always good to know, really pleased you find it useful 🙂 |
Thanks for the explanation @allmarkedup . That makes total sense. Parser errors in the UI would really be great, and I think even breaking out of Lookbook completely would be acceptable to me, depending on the level of info shown in the parsing error. Thanks for looking! |
Problem
Hello all. When the preview file has a ruby error is it declared as missing instead of reporting the error
To Reproduce
Steps to reproduce the behavior:
Work on a preview file
Change something that breaks the code. The preview now cannot be found:
Go to the rails preview to get a clue of the error
Desired behaviour
It would be great if we could see this error on Lookbook.
Version numbers
Additional context
Thanks for looking! And the continued work :) We love Lookbook! 🚀
