feature: LSP workspace diagnostics (native pull)

[disrupted]

Did you check the docs?

• I have read all the trouble.nvim docs

Is your feature request related to a problem? Please describe.

1. Neovim added native support for workspace diagnostics feat(lsp): workspace diagnostic support neovim/neovim#34262
2. but Trouble never calls vim.lsp.buf.workspace_diagnostics()
3. Without that, pull-based servers never deliver workspace results
4. DiagnosticChanged does fire correctly for unloaded buffers once the pull is triggered

Describe the solution you'd like

add support for both push-based (already exists) and pull-based LSP diagnostics (natively supported by Neovim now) in :Trouble workspace_diagnostics

Describe alternatives you've considered

Today it is only possible to use pull-based workspace diagnostics like this in Neovim:

vim.lsp.buf.workspace_diagnostics()
vim.diagnostic.setqflist({ open = true })

as a workaround I added this custom Trouble source to my config

lua/trouble/sources/diagnostics_pull.lua

---@type trouble.Source
local M = {}

local function diagnostics()
    return require 'trouble.sources.diagnostics'
end

M.highlights = {
    Message = 'TroubleText',
    ItemSource = 'Comment',
    Code = 'Comment',
}

function M.setup()
    diagnostics().setup()
end

---@param cb trouble.Source.Callback
---@param ctx trouble.Source.ctx
function M.get(cb, ctx)
    -- Always trigger a pull so results stay fresh.
    -- DiagnosticChanged will fire and trigger auto_refresh when results arrive.
    vim.lsp.buf.workspace_diagnostics()
    diagnostics().get(cb, ctx)
end

return M

Trouble config

opts = {
  modes = {
    workspace_diagnostics = {
      mode = 'diagnostics',
      source = 'diagnostics_pull',
      title = 'Workspace Diagnostics',
      auto_refresh = true,
      auto_close = false,
    }
  }
}
