* Remove the .txt suffix from tutorBlaž Hrastnik2022-09-11
| | | | | | | | | | | | The tutor file is loaded as .txt which can potentially spawn a language server. Then the path is unset, but the LS remains active. This can cause panics since updates are now submitted for a doc with no path. As a quick workaround we remove the extension which should avoid detection. Fixes #3730

* fix: Recalculate completion when going through prompt history (#3193)Frojdholm2022-08-31
| | | | | | | | | | | | | | | | | | | | | | | | * fix: Recalculate completion when going through prompt history * Update completion when the prompt line is changed It should not be possible to update the line without also updating the completion since the completion holds an index into the line. * Fix Prompt::with_line recalculate completion with_line was the last function where recalculate completion had to be done manually. This function now also recalculates the completion so that it's impossible to forget. * Exit selection when recalculating completion Keeping the selection index when the completion has been recalculated doesn't make sense. This clears the selection automatically, removing most needs to manually clear it. * Remove &mut on save_filter Co-authored-by: Blaž Hrastnik <blaz@mxxn.io>
* Derive Document language name from languages.toml name key (#3338)Michael Davis2022-08-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | * Derive Document language name from `languages.toml` `name` key This changes switches from deriving the language name from the `languages.toml` `scope` key to `name` (`language_id` in the `LanguageConfiguration` type). For the most part it works to derive the language name from scope by chopping off `source.` or `rsplit_once` on `.` but for some languages we have now like html (`text.html.basic`), it doesn't. This also should be a more accurate fallback for the `language_id` method which is used in LSP and currently uses the `rsplit_once` strategy. Here we expose the language's name as `language_name` on `Document` and replace ad-hoc calculations of the language name with the new method. This is most impactful for the `file-type` statusline element which is using `language_id`. * Use `Document::language_name` for the `file-type` statusline element The `file-type` indicator element in the statusline was using `Document::language_id` which is meant to be used to for telling Language Servers what language we're using. That works for languages with `language-server` configurations in `languages.toml` but shows text otherwise. The new `Document::language_name` method from the parent commit is a more accurate way to determine the language.
* Detect indent-style in `:set-language` (#3330)Michael Davis2022-08-05
| | | | | | | Indent style may change when choosing a language with `:set-language`. Line-endings most likely will not change, but `:set-language` should have a similar effect as reloading a file (`:reload`), plus the two are currently grouped in the implementation and line-ending detection is not particularly expensive.

* Fix byte index error in signature help highlightingGokul Soumya2022-07-29
| | | | | | | | | | | | | | | The language server sends a char offset range within the signature help label text to highlight as the current parameter, but helix uses byte offset ranges for rendering highlights. This was brought up in the [review of the original signature help PR][1], but the ranges were being highlighted correctly, and there were no out of bound or indexing panics. Turns out rust-analyzer was [incorrectly sending byte offsets] instead of char offsets and this made it seem like all was well and good with offsets in helix during initial testing.

* Reuse menu::Item trait in picker (#2814)Gokul Soumya2022-07-02
| | | | | | | | | | | | | | | | | | | | | | | | | | * Refactor menu::Item to accomodate external state Will be useful for storing editor state when reused by pickers. * Add some type aliases for readability * Reuse menu::Item trait in picker This opens the way for merging the menu and picker code in the future, since a picker is essentially a menu + prompt. More excitingly, this change will also allow aligning items in the picker, which would be useful (for example) in the command palette for aligning the descriptions to the left and the keybinds to the right in two separate columns. The item formatting of each picker has been kept as is, even though there is room for improvement now that we can format the data into columns, since that is better tackled in a separate PR. * Rename menu::Item::EditorData to Data * Call and inline filter_text() in sort_text() completion * Rename diagnostic picker's Item::Data

| * fix(command): write-quit: do not quit if write failsSkyler Hawthorne2022-06-19
| | | | | | | | | | | | | | | | | | During write-quit, if the file fails to be written for any reason, helix will still quit without saving the changes. This fixes this behavior by introducing fallibility to the asynchronous job queues. This will also benefit all contexts which may depend on these job queues. Fixes #1575

* add reflow command (#2128)Vince Mutolo2022-05-02
| | | | | | | | | | | | | | | | | | | | | | | * add reflow command Users need to be able to hard-wrap text for many applications, including comments in code, git commit messages, plaintext documentation, etc. It often falls to the user to manually insert line breaks where appropriate in order to hard-wrap text. This commit introduces the "reflow" command (both in the TUI and core library) to automatically hard-wrap selected text to a given number of characters (defined by Unicode "extended grapheme clusters"). It handles lines with a repeated prefix, such as comments ("//") and indentation. * reflow: consider newlines to be word separators * replace custom reflow impl with textwrap crate * Sync reflow command docs with book * reflow: add default max_line_len language setting Co-authored-by: Vince Mutolo <vince@mutolo.org>

* Send active diagnostics to LSP when requesting code actions. (#2005)Robin Jadoul2022-04-17
| | | | | | | | | | | * Send active diagnostics to LSP when requesting code actions. This allows for e.g. clangd to properly send the quickfix code actions corresponding to those diagnostics as options. The LSP spec v3.16.0 introduced an opaque `data` member that would allow the server to persist arbitrary data between the diagnostic and the code actions request, but this is not supported yet by this commit. * Reuse existing range_to_lsp_range functionality
