Is there a hook for project changed?

What I try todo is to call some functions when I select a project via telescope.
I saw that there are hooks for session management, but I guess it's not what I search for.

Many thanks in advance.

There is no such hook.

You can hook into switcher yourself.

local switcher = require("projections.switcher")
local original_switch_function = switcher.switch

switcher.switch = function(...)
    -- pre hooks here
    local result = original_switch_function(...)
    -- unconditional post hooks here
    if result then
        --- post hook that only runs if project switching was successful
    end
    return result
end

Additionally, if you only care about the telescope UI. You can pass in action optional argument into the picker, to perform any action you want.

More information about this is in Telescope docs.

-- The telescope UI will print details about the selection
require('telescope').load_extension('projections')
vim.keymap.set("n", "<leader>fp", function()
    local find_projects = require("telescope").extensions.projections.projections
    find_projects({ action = function(selected)
        print(vim.inspect(selected))
    end})
end)

The default action function used by projections is:

projections.nvim/lua/telescope/_extensions/projections.lua

Lines 66 to 70 in 8899141

	opts.action = function(selected)
	if selected ~= nil and selected.value ~= vim.loop.cwd() then
	switcher.switch(selected.value)
	end
	end
