Peek — A Quick Look Extension 4+

Credit where it's due...

TO THE DEVELOPER:
Speaking as A. a full-time professional software engineer, B. one who used to work for Apple, and C. one who's written QuickLook extensions in the past personally... even I gotta admit: this is pretty pimp, gentlemen. There's an almost surprising level of attention to detail in surprising places.

I don't simply mean syntax highlighting on umpteen languages (I can install Prism or a port of it too).

I mean this little stuff, like the table of contents in Markdown files, the respecting of darkmode, retention of scroll position in longer documents, or - and I LOVE this - the tabulation of YAML files. Anf you're not so pretentious as to decide I need a permanent fixture in my menu bar just for the once-a-year access I need to your preferences window. Even the background processes clean up after themselves (primary app AND helper!)! I wish ADOBE would take a lesson from y'all.

Albeit: I've not tried it on every file type yet, but if the quality level so far holds, I'm EXTREMELY optimistic.

Finally, consider, at least, accepting submissions for additional file types? I'm pretty I could get you over the hump on .docx/.xlsx... they're not that hard to parse. I assume you have this thing moduleized... wouldn't even need repo access if you posted your specs for the module. Or maybe consider an extensible API?

Regardless, totally worth the 8 bucks. There's EASILY $8 worth of love poured into this. Well done, guys!

Copy Paste from QuickLook again!

Like others, I was so desparate for this functionality (since its removal in Sierra) that I purchased this app just for that.

Then I discovered it worked by granting permissions to a helper utility to monitor inputs. No way. I deleted the entire app. Not sure how I discovered they'd come up with a different method, but I sure am glad.

As a bonus, I use Markdown a lot and for some reason one of my Macs wouldn't render it in Quicklook (despite having the same markdown quicklook plugin as all my other machines). Intalling this fixed that. Not completely stylable, but still better than plain text.

Does the job right

Update: Kudos to the developer for implementing theme choices on such short feedback.

When it comes to non-native apps for M1, there still aren't many equivalent native alternatives, specially for niche developer tools like Quick Look enhancers. This app makes for a great replacement for similar tools out there, and the preview features other than syntax highlighting, like the Markdown preview works without issues. Definitely worth the few bucks.

Developer Response ,

Syntax highlighting themes are now available.

In the update (2.4.1), Peek uses PrismJS for Python, which handles f-strings better. Be sure to change the default Prism theme from 'custom'/'custom-dark' to a different one for richer highlighting.
