This requires loading the entire file into memory, but computers are so fast today that optimizing that away is pointless IMO (as the video shows, a 12MB file with 400k lines can be loaded/edited/saved reasonably).
The tree structure is implemented as a generic container here: https://github.com/alefore/edge/blob/master/src/language/con.... The tree is actually deeply immutable; each modification operation returns a new tree (where most contents are shared with the original tree). The leafs contain std::vectors that hold between 128 and 256 lines (save for a few cases). The actual specialization that holds a sequence of lines is LineSequence::Lines here: https://github.com/alefore/edge/blob/master/src/language/tex...
That works well enough for me: https://asciinema.org/a/314752
