coc-ccls VS nerdtree

I just did a fresh reinstall of CoC, on a newer version of Neovim. I'm now seeing something I hadn't seen before, which CoC calls "inlay hints". They look like this:

As recommended by michaelsbradley below, I installed https://github.com/nim-lang/langserver. I'm using coc.nvim (https://github.com/neoclide/coc.nvim) so I followed the instructions here from nim langserver https://github.com/nim-lang/langserver#vimneovim and seems to be working well!

Actually, I'm maintaining coc-perl (https://github.com/bmeneg/coc-perl), which enables the use of Perl LSP extension for vcode on vim/neovim using the CoC (https://github.com/neoclide/coc.nvim) backend. But it's completely on top of Perl::LanguageServer.

For vim specifically, I've been using coc.nvim, which works pretty well for my needs, and I know its quite popular. Another fairly popular one is YouCompleteMe, which I had taken a look at for some other languages; but ended up just using coc as I can't justify using YCM once a year (if that) -- too much "headache" for not a lot of use, you know?

I do think VSCode is a great tool and I recommend it frequently to people, but I still want to set the record straight here. Yes, vim is obviously limited in the sense that as a CLI app it doesn't draw it's own PDF or HTML windows, that's fair. But it can remote control your favorite PDF viewer or browser for roughly the same functionality. I'm currently writing my thesis using vimtex and it's quite smooth. And all the other stuff you mention is implemented quite competently by various plugins like vim-fugitive, coc.nvim, vimspector and copilot.vim.

Sounds like you want vim-which-key and coc.nvim.

Another option is to just download https://github.com/neoclide/coc.nvim Which is basically a one stop shop for completion, and it's pretty fast, it just uses nodejs instead of built in nvim lua functions.

coc.nvim

dont over copy and paste example .vimrc, keep it simple and grow tooling as you use. for linting and code completion : https://github.com/neoclide/coc.nvim (easy to add languages)

I personally use nerdtree. Add nerdtree-git-plugin too, that's nice when looking at your project (for files, use vim-gitgutter).

nerdtree is another very popular option

Using my toy js refactoring plugin and NERDTree.

2) Syntax check https://github.com/vim-syntastic/syntastic 3) File navigation https://github.com/preservim/nerdtree 4) Autocomplete There are many autocomplete extensions. I haven't found one that I feel comfortable to recommend. Another way is to create a txt file with all the key words and lines in the languages you use, make an autocommand that adds the txt file to the buffer, and then use ctrl-n or ctrl-p to autocomplete. You can also use ctrl-x-ctrl-l to autocmplete entire lines. 5) Running code Add commands in your .vmrc to run the current file as a a whatever file. I use :J to run java files, :P to run python files, :C to run c files and so on. For example, this is my command to run a java file: command J execute "!java %:t"

My basic vim workflow is that I open vim, which opens NerdTree for me by default. I can find the file I want in NerdTree, or I can hit Ctrl+p to open a file with fuzzy searching.

What's also useful is to have a tree plugin (such as nvim-tree or nerdtree), so you can just open any file in the workspace (or outside it) if needed. That way, even if you delete a buffer, you can just come back to a file whose buffer you deleted.

Worth noting Nerdtree’s repo is now at https://github.com/preservim/nerdtree and not at https://github.com/scrooloose/nerdtree
