helix-term/commands: implement buffer-close (bc, bclose) (#1035) * helix-view/view: impl method to remove document from jumps * helix-view/editor: impl close_document * helix-view/editor: remove close_buffer argument from `close` According to archseer, this was never implemented or used properly. Now that we have a proper "buffer close" function, we can get rid of this. * helix-term/commands: implement buffer-close (bc, bclose) This behaves the same as Kakoune's `delete-buffer` / `db` command: * With 3 files opened by the user with `:o ab`, `:o cd`, and `:o ef`: * `buffer-close` once closes `ef` and switches to `cd` * `buffer-close` again closes `cd` and switches to `ab` * `buffer-close` again closes `ab` and switches to a scratch buffer * With 3 files opened from the command line with `hx -- ab cd ef`: * `buffer-close` once closes `ab` and switches to `cd` * `buffer-close` again closes `cd` and switches to `ef` * `buffer-close` again closes `ef` and switches to a scratch buffer * With 1 file opened (`ab`): * `buffer-close` once closes `ab` and switches to a scratch buffer * `buffer-close` again closes the scratch buffer and switches to a new scratch buffer * helix-term/commands: implement buffer-close! (bclose!, bc!) Namely, if you have a document open in multiple splits, all the splits will be closed at the same time, leaving only splits without that document focused (or a scratch buffer if they were all focused on that buffer). * helix-view/tree: reset focus if Tree is empty

rework positioning/rendering and enable softwrap/virtual text (#5420) * rework positioning/rendering, enables softwrap/virtual text This commit is a large rework of the core text positioning and rendering code in helix to remove the assumption that on-screen columns/lines correspond to text columns/lines. A generic `DocFormatter` is introduced that positions graphemes on and is used both for rendering and for movements/scrolling. Both virtual text support (inline, grapheme overlay and multi-line) and a capable softwrap implementation is included. fix picker highlight cleanup doc formatter, use word bondaries for wrapping make visual vertical movement a seperate commnad estimate line gutter width to improve performance cache cursor position cleanup and optimize doc formatter cleanup documentation fix typos Co-authored-by: Daniel Hines <d4hines@gmail.com> update documentation fix panic in last_visual_line funciton improve soft-wrap documentation add extend_visual_line_up/down commands fix non-visual vertical movement streamline virtual text highlighting, add softwrap indicator fix cursor position if softwrap is disabled improve documentation of text_annotations module avoid crashes if view anchor is out of bounds fix: consider horizontal offset when traslation char_idx -> vpos improve default configuration fix: mixed up horizontal and vertical offset reset view position after config reload apply suggestions from review disabled softwrap for very small screens to avoid endless spin fix wrap_indicator setting fix bar cursor disappearring on the EOF character add keybinding for linewise vertical movement fix: inconsistent gutter highlights improve virtual text API make scope idx lookup more ergonomic allow overlapping overlays correctly track char_pos for virtual text adjust configuration deprecate old position fucntions fix infinite loop in highlight lookup fix gutter style fix formatting document max-line-width interaction with softwrap change wrap-indicator example to use empty string fix: rare panic when view is in invalid state (bis) * Apply suggestions from code review Co-authored-by: Michael Davis <mcarsondavis@gmail.com> * improve documentation for positoning functions * simplify tests * fix documentation of Grapheme::width * Apply suggestions from code review Co-authored-by: Michael Davis <mcarsondavis@gmail.com> * add explicit drop invocation * Add explicit MoveFn type alias * add docuntation to Editor::cursor_cache * fix a few typos * explain use of allow(deprecated) * make gj and gk extend in select mode * remove unneded debug and TODO * mark tab_width_at #[inline] * add fast-path to move_vertically_visual in case softwrap is disabled * rename first_line to first_visual_line * simplify duplicate if/else --------- Co-authored-by: Michael Davis <mcarsondavis@gmail.com>
