How can I install all LSPs with one command?

I've seen there is a :LspUninstallAll, but no :LspInstallAll, so, how can I install all of them with one command?

Hello! As of writing there are ~115 servers available for installation. It doesn't make much sense to install all of these because

• It would carry an epic overhead, in terms of 1) the resources required to install them, and 2) the footprint it would leave on the file system
• Many languages have multiple different server implementations, for example python has 3+ servers. Using more than one per language is an extremely rare use case.

There exists an option to automatically install the servers that you actually set up, which might solve your use case:

require("nvim-lsp-installer").setup {
  automatic_installation = true
}

I know about the overhead, storage is not a problem for me and I can bear with the installation time. Plus, it's done only once

The reason I want to install them all is to have a more "set it and forget it" experience, and not need to remember to install a new LSP every time I edit a file with a different filetype

You could make use of the Lua APIs documented in :h nvim-lsp-installer and code a small snippet to install all available servers automatically. I won't write out an example here because I don't want people copy pasting it in their own configs for the reasons mentioned above!
