* feat(debug): highlight current line (#5957)Filip Dutescu2023-03-29
| | | | | | | | | | | | | | | | | | Add new theme highlight keys, for setting the colour of the breakpoint character and the current line at which execution has been paused at. The two new keys are `ui.highlight.frameline` and `ui.debug.breakpoint`. Highlight according to those keys, both the line at which debugging is paused at and the breakpoint indicator. Add an indicator for the current line at which execution is paused at, themed by the `ui.debug.active` theme scope. Update various themes to showcase how the new functionality works. Better icons are dependent on #2869, and as such will be handled in the future, once it lands. Closes: #5952 Signed-off-by: Filip Dutescu <filip.dutescu@gmail.com>

* make scrolloff calculation consistentPascal Kuthe2023-03-27
| | | | | | While scrolling (with the `scroll`) command scrolloff was calculated slightly differently than in `ensure_cursor_in_view` which could cause the cursor to get stuck while scrolling
* allow scrolling past virtual text linePascal Kuthe2023-03-27
| | | | | | | | | | | | | Virtual text lines (either caused by softwrapped inlay hints that take multiple or line annotations) currently block scrolling downwards. if the visual offset passed to char_idx_at_visual_offset or visual_offset_from_block is within a virtual text line then the char position before the virtual text and a visual offset are returned. We previously ignored that visual offset and as a result the cursor would be stuck at the start of the virtual text. This commit fixes that by simply moving the cursor to the next char (so past the virtual text) if this visual offset is non-zero

* helix-term: send the STOP signal to all processes in the process group (#3546)Cole Helbling2023-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * helix-term: send the STOP signal to all processes in the process group From kill(3p): If pid is 0, sig shall be sent to all processes (excluding an unspecified set of system processes) whose process group ID is equal to the process group ID of the sender, and for which the process has permission to send a signal. This fixes the issue of running `git commit`, attempting to suspend helix with ^Z, and then not regaining control over the terminal and having to press ^Z again. * helix-term: use libc directly to send STOP signal * helix-term: document safety of libc::kill * helix-term: properly handle libc::kill's failure I misread the manpage for POSIX `kill` -- it returns `-1` in the failure case, and sets `errno`, which is retrieved via `std::io::Error::last_os_error()`, has its string representation printed out, and then exits with the matching status code (or 1 if, for whatever reason, there is no matching status code). * helix-term: expand upon why we need to SIGSTOP the entire process group Also add a link back to one of the upstream issues.

* treat replace/insertmode consistently, default to insertPascal Kuthe2023-03-10

* fix snippet bugs and multicursor completion edgecasesPascal Kuthe2023-03-10
| | | | | | | | | | | | | | | | Multicursor completions may overlap and therefore overlapping completions must be dropped to avoid crashes. Furthermore, multicursor edits might simply be out of range if the word before/after the cursor is shorter. This currently leads to crashes, instead these selections are now also removed for completions. This commit also significantly refactors snippet transaction generation so that tabstops behave correctly with the above rules. Furthermore, snippet tabstops need to be carefully mapped to ensure their position is correct and consistent with our selection semantics. Finally, we now keep a partially updated Rope while creating snippet transactions so that we can fill information into snippets that depends on the position in the document.
* allow LSP insert text to replace non-matching prefixes (#5469)Taylor C. Richberger2023-03-10
| | | | | | | Most LSPs will complete case-insensitive matches, particularly from lowercase to uppercase. In some cases, notably Pyright, this is given as a simple insert text instead of TextEdit. When this happens, the prefix text was left unedited.
* Generalised to multiple runtime directories with priorities (#5411)paul-scott2023-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Generalised to multiple runtime directories with priorities This is an implementation for #3346. Previously, one of the following runtime directories were used: 1. `$HELIX_RUNTIME` 2. sibling directory to `$CARGO_MANIFEST_DIR` 3. subdirectory of user config directory 4. subdirectory of path to helix executable The first directory provided / found to exist in this order was used as a root for all runtime file searches (grammars, themes, queries). This change lowers the priority of `$HELIX_RUNTIME` so that the user config runtime has higher priority. More significantly, all of these directories are now searched for runtime files, enabling a user to override default or system-level runtime files. If the same file name appears in multiple runtime directories, the following priority is now used: 1. sibling directory to `$CARGO_MANIFEST_DIR` 2. subdirectory of user config directory 3. `$HELIX_RUNTIME` 4. subdirectory of path to helix executable One exception to this rule is that a user can have a `themes` directory directly in the user config directory that has higher piority to `themes` directories in runtime directories. That behaviour has been preserved. As part of implementing this feature `theme::Loader` was simplified and the cycle detection logic of the theme inheritance was improved to cover more cases and to be more explicit. * Removed AsRef usage to avoid binary growth * Health displaying ;-separated runtime dirs * Changed HELIX_RUNTIME build from src instructions * Updated doc for more detail on runtime directories * Improved health symlink printing and theme cycle errors The health display of runtime symlinks now prints both ends of the link. Separate errors are given when theme file is not found and when the only theme file found would form an inheritence cycle. * Satisfied clippy on passing Path * Clarified highest priority runtime directory purpose * Further clarified multiple runtime details in book Also gave markdown headings to subsections. Fixed a error with table indentation not building table that also appears present on master. --------- Co-authored-by: Paul Scott <paul.scott@anu.edu.au> Co-authored-by: Blaž Hrastnik <blaz@mxxn.io>
* Fix `shrink_selection` with multiple cursors. (#6093)gibbz002023-03-09
| | | | | | | | | | | * Fix #6092 Cause were some incorrect assumptions that missed an edge case in the `Selection.contains()` calculation. Tests were added accordingly. * Fix Selection.contains() edge-case handling. Removing the len check short-circuit was the only thing needed as pointed out by @dead10ck.
* correctly store snapshots when repeating insert-mode actionsPascal Kuthe2023-03-09
| | | | | | | | | | | | Repeating completions currently crates a savepoint when a completion popup was triggered (so after the request completed). Just like for normal completions the savepoint must be created at the request. The occurrence of the completion request was previously not saved in `last_insert`. To that end a new `InsertEvent::RequestCompletion` variant has been added. When replayed this event creates a snapshot that is "actived" by the `TriggerCompletion` event and subsequently used during any `InsertEvent::CompletiuonApply` events.
* discard stale completion requestsPascal Kuthe2023-03-09
| | | | | | | | | | | | | | | | | Completion requests are computed asynchronously to avoid common micro freezes while editing. This means that once a completion request completes, the state of the editor might have changed. Currently, there is a check to ensure we are still in insert mode. However, we also need to ensure that the view and document hasn't changed to avoid accidentally using a savepoint with the wrong view/document. Furthermore, the editor might request a new completion while the previous completion request hasn't complemented yet. This can lead to weird flickering or an outdated completion request replacing a newer completion that has already completed (the LSP server is not required to process completion requests in order). This change also needed to ensure determinism/linear ordering so that completion popup always correspond to the last completion request.
* store multiple snapshots on the document at oncePascal Kuthe2023-03-09
| | | | | | | | | | | | | | | | | | Fixing autocomplete required moving the document savepoint before the asynchronous completion request. However, this in turn causes new bugs: If the completion popup is open, the savepoint is restored when the popup closes (or another entry is selected). However, at that point a new completion request might already have been created which would have replaced the new savepoint (therefore leading to incorrectly applied complies). This commit fixes that bug by allowing in arbitrary number of savepoints to be tracked on the document. The savepoints are reference counted and therefore remain valid as long as any reference to them remains. Weak reference are stored on the document and any reference that can not be upgraded anymore (hence no strong reference remain) are automatically discarded.
* save selection before completion savepointPascal Kuthe2023-03-09
| | | | | | | | | Currently, the selection is not saved/restored when completion checkpoints are applied. This is usually fine because undoing changes usually restores maps selections back in insert mode. But this is not always the case and especially problematic in the presence of multi-cursor completions (since completions are applied relative to the selection/cursor) and snippets (which can change the selection)

* LSP: Support textDocument/prepareRename (#6103)Kyle Smith2023-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * LSP: Support textDocument/prepareRename 'textDocument/prepareRename' can be used by the client to ask the server the range of the symbol under the cursor which would be changed by a subsequent call to 'textDocument/rename' with that position. We can use this information to fill the prompt with an accurate prefill which can improve the UX for renaming symbols when the symbol doesn't align with the "word" textobject. (We currently use the "word" textobject as a default value for the prompt.)

* Softwrapping improvements (#5893)Clément Delafargue2023-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * use max_line_width + 1 during softwrap to account for newline char Helix softwrap implementation always wraps lines so that the newline character doesn't get cut off so he line wraps one chars earlier then in other editors. This is necessary, because newline chars are always selecatble in helix and must never be hidden. However That means that `max_line_width` currently wraps one char earlier than expected. The typical definition of line width does not include the newline character and other helix commands like `:reflow` also don't count the newline character here. This commit makes softwrap use `max_line_width + 1` instead of `max_line_width` to correct the impedance missmatch. * fix typos Co-authored-by: Jonathan Lebon <jonathan@jlebon.com> * Add text-width to config.toml * text-width: update setting documentation * rename leftover config item * remove leftover max-line-length occurrences * Make `text-width` optional in editor config When it was only used for `:reflow` it made sense to have a default value set to `80`, but now that soft-wrapping uses this setting, keeping a default set to `80` would make soft-wrapping behave more aggressively. * Allow softwrapping to ignore `text-width` Softwrapping wraps by default to the viewport width or a configured `text-width` (whichever's smaller). In some cases we only want to set `text-width` to use for hard-wrapping and let longer lines flow if they have enough space. This setting allows that. * Revert "Make `text-width` optional in editor config" This reverts commit b247d526d69adf41434b6fd9c4983369c785aa22. * soft-wrap: allow per-language overrides * Update book/src/configuration.md Co-authored-by: Pascal Kuthe <pascal.kuthe@semimod.de> * Update book/src/languages.md Co-authored-by: Pascal Kuthe <pascal.kuthe@semimod.de> * Update book/src/configuration.md Co-authored-by: Pascal Kuthe <pascal.kuthe@semimod.de> --------- Co-authored-by: Pascal Kuthe <pascal.kuthe@semimod.de> Co-authored-by: Jonathan Lebon <jonathan@jlebon.com> Co-authored-by: Alex Boehm <alexb@ozrunways.com> Co-authored-by: Blaž Hrastnik <blaz@mxxn.io>

* DynamicPicker: Recalculate column widths for new options (#6004)Michael Davis2023-03-08
| | | | | | | | | | | | | | This fixes blank row text in a DynamicPicker which is initially given no options. This can happen for language servers which respond to the workspace symbol request for an empty query with an empty list of symbols, and that behavior is somewhat common since returning all symbols as the spec suggests is very expensive. For empty options, `Picker::new` calculated the widths of each column as 0. We can recalculate the column widths when the new options are set to fix this. This refactor is also a good opportunity to formalize setting new options on a picker: besides setting the new options and calculating column widths we also want to reset the cursor and rescore the options.
* Jump to symbol ranges in LSP goto commands (#5986)Michael Davis2023-03-08
| | | | This follows prior changes like 42ad1a9e: we select the range given by the language server rather than the starting point.
* LSP: Send replies for malformed and unhandled RPC requests (#6058)Michael Davis2023-03-08
| | | | | | | | | | | | | | | | Previously we did not respond to malformed or unhandled LSP requests. The JSONRPC spec says that all non-notification requests must have responses: > When a rpc call is made, the Server MUST reply with a Response, > except for in the case of Notifications (Note that Helix is the "Server" in this case. Also from the spec: "The Server is defined as the origin of Response objects and the handler of Request objects.") So this change sends error replies for requests which can't be parsed or handled. Request IDs are also now added to the log messages for unhandled requests.
* Move terminal claim/restore code to helix-tuiMichael Davis2023-03-08
| | | | | | | | | | | | | | | | | | This moves the `Application::claim_term` and `helix-term::application::restore_term` functions into the helix-tui crate. How the terminal should be claimed and restored is a TUI concern and is implemented differently through different TUI backends. This cleans out a lot of crossterm and TUI code in Application and makes it easier to modify claim/restore based on information we query from the terminal host. The child commit will take advantage of this to cache the check for whether the host terminal supports the keyboard enhancement protocol. Without this change, caching that information takes much more code which is not easily reusable for anything else. The code to restore the terminal is somewhat duplicated by this patch: we want to restore the terminal in cases of panics. Panic handler hooks must live for `'static` and the Application's terminal does not.

* Delete snippet placeholders when accepting completionPascal Kuthe2023-03-08
| | | | | | | When accepting a snippet completion we automatically delete the placeholders for now as doing so manual is quite cumbersome. In the future we should keep these as a mark + virtual text that is automatically removed once the cursor moves there.
