Previously Alacritty was using two different ways to reference lines in the terminal. Either a `usize`, or a `Line(usize)`. These indexing systems both served different purposes, but made it difficult to reason about logic involving these systems because of its inconsistency. To resolve this issue, a single new `Line(i32)` type has been introduced. All existing references to lines and points now rely on this definition of a line. The indexing starts at the top of the terminal region with the line 0, which matches the line 1 used by escape sequences. Each line in the history becomes increasingly negative and the bottommost line is equal to the number of visible lines minus one. Having a system which goes into the negatives allows following the escape sequence's indexing system closely, while at the same time making it trivial to implement `Ord` for points. The Alacritty UI crate is the only place which has a different indexing system, since rendering and input puts the zero line at the top of the viewport, rather than the top of the terminal region. All instances which refer to a number of lines/columns instead of just a single Line/Column have also been changed to use a `usize` instead. This way a Line/Column will always refer to a specific place in the grid and no confusion is created by having a count of lines as a possible index into the grid storage. |
