LanguageClient-neovim VS GtkSharp

i know the language client neovim has such a function (:help languageclient_textdocument_codelens after compiling its helptags). AFAIK you can get that running in Vim 8, but not sure.

On NeoVim, the built-in LSP client works without modification. On Vim, you will need LanguageClient-neovim.

I'm using LanguageClient-neovim. Here's the relevant portions of my init.vim:

I just saw a nice post in /u/medwatt about using vim for VHDL/Verilog and thought I'd contribute a little! * Syntax and error highlight: https://github.com/autozimu/LanguageClient-neovim * Column align: https://github.com/junegunn/vim-easy-align * Remove annoying whitespaces: https://github.com/ntpeters/vim-better-whitespace * Partial (fuzzy) filename search: https://github.com/junegunn/fzf.vim * Outline all declarations inside a file: ⠀https://github.com/preservim/tagbar * Treat indentations as vim-objects (useful for languages that don't use { }): https://github.com/michaeljsmith/vim-indent-object There is also mouse support in vim for those who want it. Try typing :set mouse=a. Very useful for resizing windows. I also highly recommend you get good at using folds (https://vim.fandom.com/wiki/Folding). It makes it a LOT easier to navigate files. You can save your fold config per-file with :mkview and load it later with :loadview. If I come up with more hints - I'll mention them in the comments!

I've been using LanguageClient and solargraph gem with plain Vim 8 for a long time already. Still, having a bit better experience at Ruby coding with Emacs and its lsp-mode & company & inf-ruby combo.

Might migrate to Neovim's native LSP support at some point, however I find vim-lsp more feature complete out of the box. I used to use LanguageClient-neovim, however, I missed proper support for signature help.

YCM is a client. The client is a plugin for Vim or Neovim, even the "built-in" client in Neovim is just a Lua plugin that is included with the editor, it's not really built-in. Examples of other clients:LanguageClient-neovim, vim-lsp, ale.

LanguageClient-neovim just merged some support for semantic tokens and the plan, as I read the PR/issues, is to next implement some default mappings from the semantic tokens to highlight groups.

The best LSP client is the one that works for you. When it comes to neovim, there is a generous variety of LSP clients to choose from. The notables ones being vim-lsc and vim-lsp written in vimscript, LanguageClient-neovim written in rust, YouCompleteMe is written in python and in my experience is the hardest to install, coc.nvim written in typescript and, of course, the neovim's built-in one. I would recommend going with coc.nvim, as it is the best LSP client right now, though it provides much more features than a standard lsp client does and for some people it is a disadvantage and for the others it's not. Also you have to install node.js on your system for coc.nvim to work. I myself use neovim built-in one for a few reasons: it's not in stable yet, but when the neovim 0.5 version comes out, it is gonna be the standard client. Another reason is it's extremely lightweight and customizable. There were already several discussions on the subreddit about the clients you can check out.

Thanks, but I still have a question. Is that "rubber band selection" on GtkTreeView a new feature that was added to GTK4? Because, I use GTK# (the C# library for GTK) which uses GTK 3.22. I created a simple GtkTreeView, but I cannot do rubber band selection, on the same Linux PC where I recorded that rubber band selection in the OP. I wonder if this is because it is GTK3, or because I had not added the code to enable rubber band selection.

I noticed GtkSharp is on version 3.24, quite mature. I hope MS takes this seriously brings much needed Linux support, as all the dependency components are in place.

There's also the more direct route by using say Gtk directly[1].

Looks like a "blocker" is getting GtkSharp working with .Net6. Unclear from this GitHub issue when such support will be merged into the project's main branch.

For .NET GUI development on Linux, my go-to choice would be GTK#. This is a managed wrapper on GTK+2 or 3. If you have experience on developing GUI application using C and GTK+, you can reuse most of the concepts (and even some of the Glade files) in GTK#.

Your only real choice for GUI development with F#/.NET on Linux is GTK#. (I've gotten feedback on Twitter that this statement may be a bit harsh, will update when I dive a bit deeper into other options).

https://github.com/GtkSharp/GtkSharp is used rather than the mono gtk-sharp-3

mono/gtk-sharp is still stuck on 2.0 I think, but GtkSharp/GtkSharp uses 3.22 and up.
