dotfiles VS vim-ccls

Waybar natively supports this. Literally define two bars with different positions in the waybar config in a json array. You can use my dotfile as example: https://github.com/ldelossa/dotfiles/blob/e23c50698633ef0af767e37df1929d3caccbc7f1/config/waybar/config

Waybar supports multiple bars in a single config. Check out my config https://github.com/ldelossa/dotfiles/blob/master/config/waybar/config

I was relatively easy. Check out the scripts here: https://github.com/ldelossa/dotfiles/tree/master/config/sway/scripts

see: https://github.com/ldelossa/dotfiles/blob/master/config/dunst/spotify-event.sh

I've tried ccls.nvim and vim-ccls - any other recommendations?

There is Litee's Calltree but I couldn't make it work. For C/C++, there is the Vim-Ccls plugin that adds those functionalities (although I don't like the UI). But in order to use it I had to switch from Clangd to Ccls and it broke the symbol tree of 2 plugins I had : Sidebar.nvim (which I actively used) and symbols-outline.nvim (an old plugin I tried to use again, but is broken by the change as well).

First I strip down ccls like this lua local cinit = function(client) require("mappings").nvim_lsp() local rc = client.resolved_capabilities rc.document_formatting = false rc.document_range_formatting = false rc.document_highlight = false rc.document_symbol = false rc.workspace_symbol = false rc.rename = false rc.hover = false rc.completion = false rc.code_action = false end require('lspconfig').ccls.setup{ on_init = cinit, handlers = { ["textDocument/publishDiagnostics"] = function(...) return nil end, ["textDocument/signatureHelp"] = function(...) return nil end, }, single_file_support = true, root_dir = Lsp.util.root_pattern("compile_commands.json", "compile_flags.txt", ".git"), } and then use vim-ccls for the AST extensions, config it with mappings.

I use https://github.com/m-pilia/vim-ccls, and was hoping to find something more general. Thank you for making this.

you could go the route of writing your on handlers. I was incredibly lazy. there exists Martin Pilla' amazing plugin that does just that. All the hierarchy based jumps provided by ccls are inside that plugin.
