| 5072 | * direction given in the @after parameter. |
| 5073 | * |
| 5074 | * All four selection modes require different strategies. |
| 5075 | * |
| 5076 | * In char mode, what matters is which vertical character boundary is closer, taking multi-cell characters |
| 5077 | * (CJKs, TABs) into account. Given the string "abcdef", if the user clicks on the boundary between "a" |
| 5078 | * and "b" (perhaps on the right half of "a", perhaps on the left half of "b"), and moves the mouse to the |
| 5079 | * boundary between "e" and "f" (perhaps a bit over "e", perhaps a bit over "f"), the selection should be |
| 5080 | * "bcde". By dragging the mouse back to approximately the click location, it is possible to select the |
| 5081 | * empty string. This is the common sense behavior impemented by basically every graphical toolkit |
| 5082 | * (unfortunately not by many terminal emulators), and also the one we go for. |
| 5083 | * |
| 5084 | * Word mode is the trickiest one. Many implementations have weird corner case bugs (e.g. don't highlight |
| 5085 | * a word if you double click on the second half of its last letter, or even highlight it if you click on |
| 5086 | * the first half of the following space). I think it is expected that double-clicking anywhere over a |
| 5087 | * word (including the first half of its first letter, or the last half of its last letter), but over no |
| 5088 | * other character, selects this entire word. By dragging the mouse it's not possible to select nothing, |
| 5089 | * the word (or non-word character) initially clicked on is always part of the selection. (An exception |
| 5090 | * is when clicking occurred over the margin, or an unused cell in a soft-wrapped row (due to CJK |
| 5091 | * wrapping).) Also, for symmetry reasons, the word (or non-word character) under the current mouse |
| 5092 | * location is also always selected. |
| 5093 | * |
| 5094 | * Line (paragraph) mode is conceptually quite similar to word mode (the cell, thus the entire row under |
| 5095 | * the click's location is always included), but is much easier to implement. |
| 5096 | * |
| 5097 | * In block mode, similarly to char mode, we care about vertical character boundary. (This is somewhat |
| 5098 | * debatable, as results in asymmetrical behavior along the two axes: a rectangle can disappear by |
| 5099 | * becoming zero wide, but not zero high.) We cannot take care of CJKs at the endpoints now because CJKs |
| 5100 | * can cross the boundary in any included row. Taking care of them needs to go to cell_is_selected_*(). |
| 5101 | * We don't care about used vs. unused cells either. The event coordinate is simply rounded to the |
