Doc page width problem

[imkiva]

Try the following case:

var d = Doc.english("You are right, but \"Genshin Impact\" is a brand new open world adventure game by MHY.");
System.out.println(d.renderToString(16, false));

Doc will be rendered as

You are right, but
"Genshin Impact"
is a brand new open
world adventure game
by MHY

There are lines exceeding the width of 16.

I super, original

The doc printer checks whether to insert a line break or a space only in FlatAlt and Union, while Doc.english is a sequence of plain(), line(), plain(), line(), ... (line() is short for FlatAlt(a whitespace, a line break)).

The sentence above is cut into

plain(You), line(), plain(are), line(), plain(right,), line(), plain(but), line()

When the doc printed "You are right," to output, there were 2 printable widths remaining. And now we are printing the line() after plain(right,). (As described, line() = FlatAlt(a whitespace, a line break)).

• Doc printer checks if line remaining >= width of a whitespace, which evaluates to true.
• So whitespace is printed, and now the line remains only 1 character.
• Then we are printing plain(but), but this time we don't check the width.

Not really fixed

What about a plain(but) with page width 1 ?

What about a plain(but) with page width 1 ?

It will be rendered as: (no line break is inserted)

but
