21 1d08c280 2021-03-06 op * Text wrapping
22 1d08c280 2021-03-06 op * =============
24 1d08c280 2021-03-06 op * There's a simple text wrapping algorithm.
26 1d08c280 2021-03-06 op * 1. if it's a line in a pre-formatted block:
27 1d08c280 2021-03-06 op * a. hard wrap.
29 1d08c280 2021-03-06 op * 2. there is enough room for the next word?
30 1d08c280 2021-03-06 op * a. yes: render it
31 1d08c280 2021-03-06 op * b. no: break the current line.
32 1d08c280 2021-03-06 op * i. while there isn't enough space to draw the current
33 1d08c280 2021-03-06 op * word, hard-wrap it
34 1d08c280 2021-03-06 op * ii. draw the remainder of the current word (can be the
35 1d08c280 2021-03-06 op * the entirely)
36 1d08c280 2021-03-06 op * 3. render the spaces after the word
37 1d08c280 2021-03-06 op * a. but if there is not enough room break the line and
42 1d08c280 2021-03-06 op * Text scrolling
43 1d08c280 2021-03-06 op * ==============
45 1d08c280 2021-03-06 op * ncurses allows you to scroll a window, but when a line goes out of
46 1d08c280 2021-03-06 op * the visible area it's forgotten. We keep a list of formatted lines
47 1d08c280 2021-03-06 op * (``visual lines'') that we know fits in the window, and draw them.
48 1d08c280 2021-03-06 op * This way is easy to scroll: just call wscrl and then render the
49 1d08c280 2021-03-06 op * first/last line!
51 1d08c280 2021-03-06 op * This means that on every resize we have to clear our list of lines
52 1d08c280 2021-03-06 op * and re-render everything. A clever approach would be to do this
53 1d08c280 2021-03-06 op * ``on-demand''.
55 1d08c280 2021-03-06 op * TODO: make the text formatting on-demand.
