Michael Davis	5f043dde56	Derive Document language name from languages.toml name key (#3338) ... * 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.	2 years ago

Mr. E	b05fcaadad	Indent with tabs by default (#3095)	2 years ago
Skyler Hawthorne	0f3c10a021	Fix initial selection of Document in new view ... When a new View of a Document is created, a default cursor of 0, 0 is created, and it does not get normalized to a single width cursor until at least one movement of the cursor happens. This appears to have no practical negative effect that I could find, but it makes tests difficult to work with, since the initial selection is not what you expect it to be. This changes the initial selection of a new View to be the width of the first grapheme in the text.	2 years ago

Skyler Hawthorne	a494f47a5d	Configurable auto pairs (#1624) ... * impl auto pairs config Implements configuration for which pairs of tokens get auto completed. In order to help with this, the logic for when *not* to auto complete has been generalized from a specific hardcoded list of characters to simply testing if the next/prev char is alphanumeric. It is possible to configure a global list of pairs as well as at the language level. The language config will take precedence over the global config. * rename AutoPair -> Pair * clean up insert_char command * remove Rc * remove some explicit cloning with another impl * fix lint * review comments * global auto-pairs = false takes precedence over language settings * make clippy happy * print out editor config on startup * move auto pairs accessor into Document * rearrange auto pair doc comment * use pattern in Froms	3 years ago

Current time is now by default, or the commit time if :before has just been used. * Add :earlier an :later commands that can move through the edit history and retrieve changes hidded by undoing and commiting new changes. The commands accept a number of steps or a time period relative to the currrent change. * Fix clippy lint error. * Remove the dependency on parse_duration, add a custom parser instead. * Fix clippy errors. * Make helix_core::history a public module. * Use the helper for getting the current document and view. * Handled some PR comments. * Fix the logic in :later n.
