* Improve error message handling for theme loading failures (#5073)Michael Davis2022-12-15
| | | | | | | | | | | | | | | | | The error messages for a theme that failed to be deserialized (or otherwise failed to load) were covered up by the context/with_context calls: * The log message for a bad theme configured in config.toml would only say "Failed to deserilaize theme" * Selecting a bad theme via :theme would show "Theme does not exist" With these changes, we let the TOML deserializer errors bubble up, so the error messages can now say the line number of a duplicated key - and that key's name - when a theme fails to load because of a duplicated key. Providing a theme which does not exist to :theme still gives a helpful error message: "No such file or directory."
* Reset mode when changing buffers (#5072)Michael Davis2022-12-11
| | | | | | | | | | | | | | * Reset mode when changing buffers This is similar to the change in e4c9d4082a139aac3aea4506918171b96e81f5b9: reset the editor to normal mode when changing buffers. Usually the editor is already in normal mode but it's possible to setup insert-mode keybindings that change buffers. * Move normal mode entering code to Editor This should be called internally in the Editor when changing documents (Editor::switch) or changing focuses (Editor::focus).

* fix: align view after jumplist_picker (#3743)Narazaki Shuji2022-12-06
| | | | | | | | | * Add `View::ensure_cursor_in_view_center` to adjust view after searching and jumping Also `offset_coodrs_to_in_view` was refactored to reduce duplicated position calculations. * Fix a wrong offset calculation in `offset_coords_to_in_view_center` It ignored `scrolloff` if `centering` is false.

* Handle disambiguated keycodes (#4887)Michael Davis2022-11-29
| | | | | Media keys are sent despite `DISAMBIGUATE_ESCAPE_CODES` being unset. Previously we panicked on these. This change translates the disambiguated keys from crossterm so that they do not cause a panic.

* Revert "Don't apply transactions to Views in undo/redo"Michael Davis2022-11-29
| | | | This reverts commit fd00f3a70eb626242bb2fcc9bddf2c4d94580a9a.
* Remove selections for closed views on all documents (#4888)Michael Davis2022-11-26
| | | | | Previously we removed selections for a closed view on only the currently focused document. A view might have selections in other documents though, so the view needs to be removed from all documents.
* Don't apply transactions to Views in undo/redoMichael Davis2022-11-24
| | | | | | View::apply should only be called by EditorView after 42e37a571e75aaf4feb1717dfebe8cf215e535dd. This change removes the duplicate calls within undo/redo which could cause a panic.
* Apply transactions to all views (#4733)Michael Davis2022-11-23
| | | | | | | | | | | | | | | | | * Add a test case for updating jumplists across windows * Apply transactions to all views on history changes This ensures that jumplist selections follow changes in documents, even when there are multiple views (for example a split where both windows edit the same document). * Leave TODOs for cleaning up View::apply * Use Iterator::reduce to compose history transactions Co-authored-by: Blaž Hrastnik <blaz@mxxn.io> Co-authored-by: Blaž Hrastnik <blaz@mxxn.io>
* Limit the number of items in the jumplist (#4750)Michael Davis2022-11-22
| | | | | | | | | | | | | | | | | | | | | Previously, jumplists could grow unchecked. Every transaction is applied to jumplist selections to ensure that they are up to date and within document bounds, so this would cause every edit to become more expensive as jumplist lengths increased throughout a session. Setting a maximum number of entries limits the cost. Vim and Neovim limit their jumplists: * https://github.com/vim/vim/blob/b298fe6cbae3b240b10dbd55d9c38d0cc8e033d3/src/structs.h#L141 * https://github.com/neovim/neovim/blob/e8cc489accc435076afb4fdf89778b64f0a48473/src/nvim/mark_defs.h#L57 Notably, Kakoune does not. In Kakoune, changes are applied to jumplist entries lazily as you hit `<C-o>`/`<C-i>` though, so Kakoune doesn't have the same growing cost concerns. Kakoune also does not have a concept of a View which limits the cost further. Vim and Neovim limit to 100. This seems unreasonably high to me so I've set this to 30 to start. We can increase if this is problematically low.

* Factor out common code for focusing the next view (#4607)Michael Davis2022-11-17
| | | | | There is some common code between Editor::focus_next and Editor::focus that can be eliminated by refactoring Tree::focus_next into a function that only returns the next ViewId.

* Fix panic from two windows editing the same document (#4570)Michael Davis2022-11-03
| | | | | | | | | | | | | | | | | | | | * Clamp highlighting range to be within document This fixes a panic possible when two vsplits of the same document exist and enough lines are deleted from the document so that one of the windows focuses past the end of the document. * Ensure cursor is in view on window change If two windows are editing the same document, one may delete enough of the document so that the other window is pointing at a blank page (past the document end). In this change we ensure that the cursor is within view whenever we switch to a new window (for example with `<C-w>w`). * Update helix-term/src/ui/editor.rs Co-authored-by: Blaž Hrastnik <blaz@mxxn.io> Co-authored-by: Blaž Hrastnik <blaz@mxxn.io>
* Use OSC 52 as a fallback for setting the system clipboard (#3220)Charlie Groves2022-11-02
| | | | | This adds a simple base64 implementation to keep us from adding a crate for one function. It's mostly based on https://github.com/marshallpierce/rust-base64/blob/a675443d327e175f735a37f574de803d6a332591/src/engine/naive.rs#L42
* Allow the area to be bigger than u16 (width and height remain u16) (#4318)A-Walrus2022-10-26
| | | | Now the editor can fill **very** large terminals. Changed/removed tests which check the truncating behaviour.
* commands: Make no arg ':theme' show name (#3740)James O. D. Hunt2022-10-26
| | | | | | | | | | | | | | | | Most commands that accept an argument show their current value if no argument is specified. The `:theme` command previously displayed an error message in the status bar if not provided with an argument: ``` Theme name not provided ``` It now shows the current theme name in the status bar if no argument is specified.

* Fix multi byte auto pairs (#4024)Skyler Hawthorne2022-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Fix test::print for Unicode The print function was not generating correct translations when the input has Unicode (non-ASCII) in it. This is due to its use of String::len, which gives the length in bytes, not chars. * Fix multi-code point auto pairs The current code for auto pairs is counting offsets by summing the length of the open and closing chars with char::len_utf8. Unfortunately, this gives back bytes, and the offset needs to be in chars. Additionally, it was discovered that there was a preexisting bug where the selection was not computed correctly in the case that the cursor was: 1. a single grapheme in width 2. this grapheme was more than one char 3. the direction of the cursor is backwards 4. a secondary range In this case, the offset was not being added into the anchor. This was fixed. * migrate auto pairs tests to integration * review comments
