mock up affordances for moving and resizing A node will take up as much vertical space as it needs given its text. But we can resize its width. 2023-04-18 07:22:01 +01:00			`on_resize = function(sx,sy)`
switch Nodes from array to table We need keys to be fixed as we add/delete nodes because we're going to start recording them next inside Nodes to encode edges. Since there isn't a clear name for nodes in this app, I came up with a way to autogenerate keys. 2023-04-18 16:09:27 +01:00			`for _,node in pairs(Nodes) do`

start implementing the mouse handler Until now the hover actions were happening in surface coordinates sx/sy but the mouse press action (done so far) was happening in viewport coordinates vx/vy. Now it's consistent. Surface coordinates make more sense since most data in memory uses them. 2023-04-18 07:28:42 +01:00			`return node`
