neovide's Introduction

Neovide

This is a simple graphical user interface for Neovim (an aggressively refactored and updated Vim editor). Where possible there are some graphical improvements, but functionally it should act like the terminal UI.

To checkout all the cool features, installation instructions, configuration settings and much more, head on over to neovide.dev.

Author Notes

I've been using this as my daily driver since November 2019. It should be relatively stable, but I'm still working out some kinks and ironing out some cross platform issues. In general it should be usable at this point, and if it isn't I consider that a bug and appreciate a report in the issues! Any help and ideas are also greatly appreciated.

I'm also very interested in suggestions code quality/style wise when it comes to Rust. I'm pretty new to the language and appreciate any critiques that you might have to offer. I won't take all of them, but I promise to consider anything you might have to offer.

neovide's Issues

Postscript error on linux

When I try to run neovide on Ubuntu 19.10 I get the following error: Failed to load by postscript name: NotFound. Then it exits without opening any GUI window.

Running with a stack trance gives this:

Bridge created.

Make Messagebox Errors Optional

Add a feature which disables the msgbox dependency which requires libgtk on linux.

show proper error message when nvim.exe can't be found

Currently it silently exits and you don't know what is going on. Had to enable the rust backtrace in debug mode.

OS: Windows

Weird positioning of special glyphs

Switch to pathfinder

Investigate blurred floating windows/popups

provide instructions for mac to build

Currently I'm using brew cask install apenngrace/vulkan/vulkan-sdk and it runs properly.

doesn't start on Win10 with nvim-nightly

Hi, I wanted to check neovide but it doesn't start for me.

I use neovim-nightly, installed via scoop (it works ok as a standalone and embedded as a firenvim in firefox)

Updates Missed

Sometimes when I press a key, nothing happens. I suspect there is some kind of race condition that I haven't fully thought of yet, because most of the time responses to key presses are rendered correctly. Not sure what is going wrong here...

Add neovide to external projects page

Handle Gui Options

Just record them for now and store them in the editor

Emoji positioning

Emojis are slightly offset to the right. Would be nice to center them better.

Setup Github Actions to Build and Publish Assets

Weirdly bold text

Strange Clear Errors

Ever since the rewrite to use nvim_rs I've gotten weird redraw errors. Not sure if its a race condition problem or if nvim_rs messes with the event orders...

Externalize Messages

This should get rid of the bottom line (and maybe solve the giant message line bug)

Reduce Cpu Const in build_draw_commands

Currently we rebuild commands every time. Instead it would be better to record the draw command from neovim and just send them instead of rebuilding.

Backtracking will be necessary to make sure ligatures are handled properly
Scrolling must emit the entire scroll region as neovim doesn't handle these for us

This isn't a huge issue anymore given that progressive rendering is now working, but its a nice to have

Investigate Exposing UI Extensions to Vimscript

It would be interesting to support the message and command line extensions by rerouting them back to vimscript via events.

It would be awesome to let the user implement messages/commandline using libraries such as https://www.reddit.com/r/neovim/comments/dd8o0w/use_floating_windows_to_show_notifications_in/
or similar.
If I combine this with the ability to set text size on a per window basis it could be very powerful.

Handle horizontal scrolling

Window Clearing

Sometimes remnants of popup windows are kept around. I'm not sure what causes this, but this shouldn't happen.

This will be fixed with the multigrid support in the future, but it is indicative of an algorithm problem.

Weird over zealous underline

Error compiling for linux

When I compile on Linux (Ubuntu 19.10 Gnome) it successfully compiles a long list of dependencies but eventually gets stuck with:

error: failed to run custom build command for `atk-sys v0.6.0`

Caused by:
  process didn't exit successfully: `/home/quinn/neovide/target/release/build/atk-sys-268e6b6307e121eb/build-script-build` (exit code: 1)
--- stderr
`"pkg-config" "--libs" "--cflags" "atk" "atk >= 2.4"` did not exit successfully: exit code: 1

Package atk was not found in the pkg-config search path.
Perhaps you should add the directory containing `atk.pc'
to the PKG_CONFIG_PATH environment variable
No package 'atk' found
Package atk was not found in the pkg-config search path.
Perhaps you should add the directory containing `atk.pc'
to the PKG_CONFIG_PATH environment variable
No package 'atk' found

Is there an extra step I need to do to make sure atk is installed? I don't have the PKG_CONFIG_PATH variable set. It seems like I could just set it to point to this 'atk.pkg' file, but I don't know where it is and/or how to download it.

Resizing then Scrolling does weird things

Embed Default Font

Currently if the default font isn't found installed on the system, the font system will default to Delugia Nerd Font with size 14. This isn't great because it assumes that the nerd font is installed on all systems.

Instead I should embed the nerd font file into the executable using one of the Rust binary embedder projects and use that for the default so that the base experience looks good, and supports powerline options.

Alternative to neovim-lib

Hey, hope you don't mind this issue, feel free to delete/close it if you feel this is an intrusion.

I'm working on a fork of neovim-lib that I'd like to advertise a bit. It started with the idea to leverage async/await to allow for arbitrarily nested requests, but has grown into more of a rewrite, since I saw the chance to follow some ideas of my own :) It's definitely not API compatible, of course, but has already gotten some features I deem improvements.

If you're interested, I'd dearly like some feedback on it, and I'd certainly be open to requests/ideas, so if you want some influence on the lib you're using, it's a good time to get into touch.

Thanks for reading, and thanks for sharing your project :)

Runtime error [linux/wayland]

Running on wlroots/wayfire nightly

UI thread spawned thread 'main' panicked at 'Failed to create renderer: CreateInstanceError(InstanceError(VkError(ERROR_EXTENSION_NOT_PRESENT)))', src/libcore/result.rs:1165:5

Build better default font support

Failing to set the font early enough in the init file causes neovide to crash because it can't find the default delugia font.

Either I need to swap the default to a system default, or I need to embed delugia.

In any case checking if the font is available first is a good call.

Rendering stutters when inputing keys/dragging mouse

I think the editor mutex gets locked which blocks the window thread. Some better strategy for communication between the editor and the renderer/window seems wise.

Add app icon to executable on linux and mac

It is a GUI app after all :)

Not in hurry but nice to have. Might be for now can just use the default neovim assets?

Fix Bold and Italic

The font discovery fix killed bold and italic. They need revived.

Add Gui Options

Currently the only special thing we do that someone would like to disable is the animated cursor. I can probably get away with not allowing disabling of the animated cursor, but it would be very nice to make it configurable before release.

Handle Cursor Options

Blink and Width percent

Error in nvim-rs dependency

When running cargo build --release from a fresh clone, there's an error on fetching the nvim-rs dependency. Looking at Cargo.toml, it appears that this dependency is from https://github.com/KillTheMule/nvim-rs and specifies the branch "futures". However, it looks like this branch was merged a few days ago: KillTheMule/nvim-rs#11

Fixing this dependency fixes the build, though!

Failed to run release on macos.

I recently followed the instructions for macOS and even downloaded the vulcan-sdk package using brew. Unfortunately, it didn't work. The error output I got is :

Bridge created.
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', src/libcore/option.rs:378:21
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace.

I hope this may help you debug this issue for macOS users. Thanks!

Might be upstream, but should look at the issue here to be sure
