This doesn't affect this fork directly, but it's a bad idea to assume
the _app_ is always going to be doing just what a particular subsystem
(here, the text editor in edit.lua+text.lua) is doing.
I think all we need to maintain is the populate_screen_line_starting_pos
array. It's easy to render screen lines one by one from it, and we'll
only ever construct one additional screen line at a time.
I'd hoped to delete other calls to Text.populate_screen_line_starting_pos,
but it turns out we need to update it when editing sometimes. Give up on
that for now; it's a no-op if not needed.
I see a path to at least maintain a single fragment per screen line. But
can we do better? It even seems unnecessary to maintain two copies of
the data, chopped up into lines and screen lines.
I've been misunderstanding what Text objects are. They can render a lot
of text with a given line height, word wrap, colors in various places.
And I've been creating one for every word 🤦
Unwinding this will take some time. This is just a first baby step for
ad hoc text objects. Turns out I don't need to convert to Text to get
something's rendered width, just the Font can do that.

This works better on mobile platforms while seeming about as useful
anywhere else.
I've verified that anyone who already edited a file will continue to use
its path from settings.
It's just uneconomic to maintain given how little I've used it. I have a
bug right now and no time to port the bugfix to all the complexities of
the B side.
I briefly considered tossing out the entire source editor. But I _have_
been using it to browse logs across sessions. The live editor doesn't
quite cover all my use cases just yet.
We now have duplication in the source editor only for:
* syntax highlighting
* hyperlinking [[WikiWords]]
* ability to hide cursor (when showing file browser or Focus is in log browser)
scenario:
press ctrl+f, type in a string
hit down arrow if needed until the screen scrolls
press enter
click with the mouse somewhere
Before this commit the app would crash because cursor was above screen
top.
Currently only used in pong.love, but let's keep the bad merge that had
it broken since September from occurring again. To do that we'll be
consistent across forks on where globals are initialized.
I haven't appreciated the implications of main.lua for load order.
log.lua comes first just because it's shared by both the main app and
its 'source' editing environment. And it just so happens that source.lua
was loading after log.lua resulting in the pong.love breakage. Now let's
lean into that and enshrine that one should initialize log_render in
log.lua.
I've been noticing in pensieve.love in particular that once a month or
so I lose data if I quit immediately after typing in something. Nothing
major, just the odd link between notes which leaves things in an
inconsistent state. Let's see if this helps.
