Prettier is a JavaScript-based formatter that I use for this very site’s codebase, since it is quite extensible and can handle a wide variety of formats. I recently noticed a specific quirk with it where you need to specifically pre-format JSX in a certain way to get a specific output from it. With this source document and no formatting configured: <Figure src={lego_dino_onesie} alt="A large red LEGO character wearing a dino onesie holding a small dinosaur egg" /> <Gallery> <Figure src={lego_dino_onesie} alt="A large red LEGO character wearing a dino onesie holding a small dinosaur egg" /> <Figure src={lego_spiderman} alt="A LEGO Spider-Man figure displayed among other models" /> </Gallery> You will get this output (Prettier playground): <Figure src={lego_dino_onesie} alt="A large red LEGO character wearing a dino onesie holding a small dinosaur egg" /> <Gallery> <Figure src={lego_dino_onesie} alt="A large red LEGO character wearing a dino onesie holding a small dinosaur egg" /> <Figure src={lego_spiderman} alt="A LEGO Spider-Man figure displayed among other models" /> </Gallery> Notice how the outer Figure is now 2 space indented but the inner ones didn’t change? Here’s how you need to manually lay out the inner text for Prettier to format it like the other one: <Figure src={lego_dino_onesie} alt="A large red LEGO character wearing a dino onesie holding a small dinosaur egg" /> <Gallery> <Figure src={lego_dino_onesie} alt="A large red LEGO character wearing a dino onesie holding a small dinosaur egg" /> <Figure src={lego_spiderman} alt="A LEGO Spider-Man figure displayed among other models" /> </Gallery> Formatting this version with Prettier will give you the expected variant (Prettier playground): <Figure src={lego_dino_onesie} alt="A large red LEGO character wearing a dino onesie holding a small dinosaur egg" /> <Gallery> <Figure src={lego_dino_onesie} alt="A large red LEGO character wearing a dino onesie holding a small dinosaur egg" /> <Figure src={lego_spiderman} alt="A LEGO Spider-Man figure displayed among other models" /> </Gallery> I think it will be fixed by this PR, but it has been in-progress for nearly 10 months now without any indication of an imminent merge.
