    Another unpopular opinion about CSS: CSS makes Knuth line breaking hard, but I actually think that’s the *right* call. Greedy line breaking makes it so much easier to support layout features you actually want. Many things are hard in TeX because it does Knuth line breaking.https://twitter.com/littledan/status/1109521891864338438 …

        Why do these conflict? Why does greedy do anything other than run faster?

        Knuth line breaking is basically “try all the possibilities”, so you end up having to either (a) worry about memory consumption from lots of potential layout trees or (b) have the ability to “undo” your changes as you go. Either is nontrivial.

        is there some place where text layout/shaping/etc. is explained in any way nicer than (pseudocode or not) algorithms? but maybe I shouldn't know too much, lest I make yet another text thing which is the opposite of accessible, even if aesthetically pleasing by some miracle

        Here’s a good explanation I found of Knuth line breaking: http://defoe.sourceforge.net/folio/knuth-plass.html …

        Yeah, but can you blame Knuth, I mean, his name is on the algorithm, he didn’t have much choice

        What are the layout features you want that are easier to support with greedy algorithms?

        How does css specify a line breaking algorithm? Or did I misinterpret the tweet?
