Triggering preinstallation

[dominicmeyer]

Hi,

I'm using neovim inside docker, because of this it's common, that I start with a "clean" neovim installation (of course I use my config everytime, but there is nothing installed on the system, other than the config).
To reduce the startup phase I've added nvim --headless "+Lazy! sync" +qa to my Docker build steps, so the plugins will be installed once before starting. This works great, but I can't find a way, to preinstall my configured language servers with mason. I assume this is caused by lazy.nvim, but if this should be an issue with mason, I'll move this to their repo.

27     'L3MON4D3/LuaSnip',
28     version = "v2.1.0"
29   }
30 } 

I image the issue is happening, because with the --headless cmd lazy only loads all the configured plugins and not executes all files in init.lua. So is there maybe another way, to fully execute the init.lua? Btw I also tried to use some other nvim command line options, to run it, but they all failed:

nvim -ll /root/.config/nvim/init.lua
nvim -l /root/.config/nvim/init.lua --headless +qa
nvim -S /root/.config/nvim/init.lua --headless +qa

I have similar problem and manage to solve it with the following line

Dockerfile code

RUN nvim "+Lazy! install" +MasonToolsInstallSync +q!

I know this is an old post, but this answer might help someone else encountering the same problem

[the-citto]

thank you both, needed the same and got a great head start

unfortunately for me MasonToolsInstallSync didn't work - perhaps it's available with some additional dependency, but googling for it this thread is the only place that come up

ended up with

RUN nvim --headless "+Lazy! update" +q!

RUN nvim --headless "+MasonInstall eslint_d" +q!
RUN nvim --headless "+LspInstall [email protected]" +q!
RUN nvim --headless "+LspInstall clangd" +q!
RUN nvim --headless "+LspInstall cssls" +q!
RUN nvim --headless "+LspInstall html" +q!
RUN nvim --headless "+LspInstall jsonls" +q!
RUN nvim --headless "+LspInstall lua_ls" +q!
RUN nvim --headless "+LspInstall pyright" +q!
RUN nvim --headless "+LspInstall ruff" +q!
RUN nvim --headless "+LspInstall rust_analyzer" +q!
RUN nvim --headless "+LspInstall sqlls" +q!
RUN nvim --headless "+LspInstall taplo" +q!
RUN nvim --headless "+LspInstall tsserver" +q!
# RUN nvim --headless "+LspInstall r_language_server" +q!

a bit annoying, considering the time I spent to find how to orchestrate Mason, Mason-Lspconfig, and Lspconfig to have the LSPs all declared in one place
still, not too bad

using LspInstall vs MasonInstall since I like writing server names more than package names
looked to do the same for eslint_d with nvim-lint, but there MasonInstall will do - perhaps the same will be true when I'll finally set up DAP

@the-citto @dominicmeyer @krononava can you share your config, because when I try

# Install Tree-sitter parsers during the build
RUN nvim --headless "+TSInstallSync all" +qall

I am getting:

Error detected while processing command line:
E492: Not an editor command: TSInstallSync all
