* feat(commands): shrink_selection (#1340)Matouš Dzivjak2022-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * feat(commands): shrink_selection Add `shrink_selection` command that can be used to shrink previously expanded selection. To make `shrink_selection` work it was necessary to add selection history to the Document since we want to shrink the selection towards the syntax tree node that was initially selected. Selection history is cleared any time the user changes selection other way than by `expand_selection`. This ensures that we don't get some funky edge cases when user calls `shrink_selection`. Related: https://github.com/helix-editor/helix/discussions/1328 * Refactor shrink_selection, move history to view * Remove useless comment * Add default key mapping for extend&shrink selection * Rework contains_selection method * Shrink selection without expand selects first child

* helix-term/commands: implement buffer-close (bc, bclose) (#1035)Cole Helbling2021-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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
