Is there a way to reconfigure a server's config after entering vim?

[kedodrill]

Hi there, thank you for this plugin!

I'm trying to set the environment.phpVersion config for the intelephense (PHP) server dynamically. Unfortunately intelephense does not do this automatically.

In neovim, I did this using the on_init function provided by nvim-lspconfig. Is there something similar I can use here, or can I use some kind of vimscript to do this?

Conditionally adding the server if vim is opened in a directory where there is a composer.json file does work, but it would be nice to be able to set the version so I can move around to different projects within vim.

Here is what I have right now. (github doesn't support vim9script yet I don't think? this is all in vim9script).

def GetPHPVersion():string
" ...
enddef

var lspServers = []

if (filereadable('composer.json'))
    lspServers->add({
        " intelephense...
        workspaceConfig: { intelephense: { environment: { phpVersion: GetPHPVersion() } } }
    })
endif

What I would like to see is something like this (I think this is valid vim9script...but not sure. you get the idea though):

" ...
var lspServers = []
var intelephense = {
    " intelephense...
}
" onInit (optional): each time the server is started, execute an inline function that has the settings as a param and changes the settings
intelephense.onInit = (intelephense) => {
    intelephense.workspaceConfig = {
        intelephense: { environment: { phpVersion: GetPHPVersion() } }
    }
}
lspServers->add(intelephense)
