* Add runtime language configuration (#1794) (#1866)Roland Kovacs2022-04-05
| | | | | | | | | | | | | | | | | | | | | * Add runtime language configuration (#1794) * Add set-language typable command to change the language of current buffer. * Add completer for available language options. * Update set-language to refresh language server as well * Add language id based config lookup on `syntax::Loader`. * Add `Document::set_language3` to set programming language based on language id. * Update `Editor::refresh_language_server` to try language detection only if language is not already set. * Remove language detection from Editor::refresh_language_server * Move document language detection to where the scratch buffer is saved. * Rename Document::set_language3 to Document::set_language_by_language_id. * Remove unnecessary clone in completers::language
* Resolve conflicts between prompt/picker bindings (#1792)Rohan Jain2022-03-31
| | | | | | | | | | | | | | Currently, the picker's re-using a few bindings which are also present in the prompt. This causes some editing behaviours to not function on the picker. **Ctrl + k** and **Ctrl + j** This should kill till the end of the line on prompt, but is overridden by the picker for scrolling. Since there are redundancies (`Ctrl + p`, `Ctrl + n`), we can remove it from picker. **Ctrl + f** and **Ctrl + b** This are used by the prompt for back/forward movement. We could modify it to be Ctrl + d and Ctrl + u, to match the `vim` behaviour.

* Optimize rendering by using Ropey::byte_sliceBlaž Hrastnik2022-03-17
| | | | | | | This avoids costly conversions via byte_to_char (which are then reversed back into bytes internally in Ropey). Reduces time spent in slice/byte_to_char from ~24% to ~5%.
* Handle panic on move within empty picker (#1786)Rohan Jain2022-03-14
| | | | | | | | | When the picker results output is empty, movement actions result in a panic: ``` thread 'main' panicked at 'attempt to calculate the remainder with a divisor of zero', helix-term/src/ui/picker.rs:420:31 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace ``` This could be a no-op instead when the matches length is zero.

* migrate grammar fetching/building code into helix-loader crateMichael Davis2022-03-10
| | | | | | | | | This is a rather large refactor that moves most of the code for loading, fetching, and building grammars into a new helix-loader module. This works well with the [[grammars]] syntax for languages.toml defined earlier: we only have to depend on the types for GrammarConfiguration in helix-loader and can leave all the [[language]] entries for helix-core.

* Show infobox to hint textobjects with `mi` and `ma` (#1686)Daniel S Poulin2022-03-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Show infobox to hint textobjects with `mi` and `ma` * Add note to infobox than any pair of characters will work too The wording could probably be a little more clear, but I wanted to keep it short but still accurate. * Don't allocate a vec for the static help text * Fix bug where `mi<esc>` would swallow next input and persist infobox * Better help text for arbitrary pair matching in textobject selection * Add way to add fake pending key data below status, use with `mi`/`ma` This is a bit hacky as it makes use of global state which will end up managed in multiple places, but has precedent in the way autoinfo works. There should probably be a bigger refactor to handle this kind of state better. * Return early on anything other than `mi` and `ma` for autoinfo * Remove "ascii" from help text with `mi` and `ma` * Update helix-term/src/ui/editor.rs Co-authored-by: Blaž Hrastnik <blaz@mxxn.io>
* Minor cleanup of file picker file gathering logic (#1683)Daniel S Poulin2022-03-01
| | | | | | | | | | | | | * Refactor file picker filetype filter logic to remove panic, make clearer An unwrap was unneccesarily present due to a prior contribution of mine which was before I had any understanding of error handling in Rust. I've also swapped a match for an if let, as was originally suggested in the original pull request adding filetype filtering, but was merged before I could address. * Add some comments to the file picker code for clarity * Switch to expect instead of ignoring type def error
* ignore Enter keypress when menu has no selection (#1704)Michael Davis2022-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * ignore Enter keypress when menu has no selection supersedes #1622 Builds on the work in #1285. I want to allow Enter to create a newline when there is no selection in the autocomplete menu. This occurs somewhat often when using LSP autocomplete in Elixir which uses `do/end` blocks (and I set the autocomplete menu delay to 0 which exacerbates the problem): ```elixir defmodule MyModule do def do_foo(x) do x end def other_function(y) do| end ``` Here the cursor is `|` in insert mode. The LSP suggests `do_foo` but I want to create a newline. Hitting Enter currently closes the menu, so I end up having to hit Enter twice when the module contains any local with a `do` prefix, which can be inconsistent. With this change, we ignore the Enter keypress to end up creating the newline in this case. * pop compositor layer when ignoring Enter keypress * move closing function out of consumed event result closure * explicitly label close_fn as an 'Option<Callback>'

| | | | | Some users (including myself) want to turn off filtering of files prefixed with `.`, as they are often useful to edit. For example, `.env` files, configuration for linters `.eslint.json` and the like.
