# TODO: works great for moving within wrapped line,
|
|
# not quite when moving from wrapped to normal and vice versa
|
|
# 1. Detect line-wrap status of target line before deciding to do vertical jump or visual column shift
|
|
# 2. Load the target line in addition
|
|
# 3. Use the same wrap_width logic to compare visual row availability
|
|
# on the target line
|
|
|
|
# Basically, look at the target line, and figure out the logical column
|
|
# number that corresponds to the visual column number we see right now.
|
|
|
|
# Also TODO: once this is ironed out, re-write it in Rust for le speed
