From 96898e05a628b865dc4c457e7345d404cfe2ae77 Mon Sep 17 00:00:00 2001 From: Matthew Wild Date: Fri, 23 Feb 2024 21:13:10 +0000 Subject: mod_server_info: New module to manage the serverinfo disco extension form This allows multiple modules to populate the form dynamically. Currently the form is "owned" by mod_server_contact_info, which prevents other modules from contributing to it. A further commit will port mod_server_contact_info to use this module. --- plugins/mod_server_info.lua | 55 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 55 insertions(+) create mode 100644 plugins/mod_server_info.lua (limited to 'plugins') diff --git a/plugins/mod_server_info.lua b/plugins/mod_server_info.lua new file mode 100644 index 00000000..5469bf02 --- /dev/null +++ b/plugins/mod_server_info.lua @@ -0,0 +1,55 @@ +local dataforms = require "prosody.util.dataforms"; + +local server_info_config = module:get_option("server_info", {}); +local server_info_custom_fields = module:get_option_array("server_info_extensions"); + +-- Source: http://xmpp.org/registrar/formtypes.html#http:--jabber.org-network-serverinfo +local form_layout = dataforms.new({ + { var = "FORM_TYPE"; type = "hidden"; value = "http://jabber.org/network/serverinfo" }; +}); + +if server_info_custom_fields then + for _, field in ipairs(server_info_custom_fields) do + table.insert(form_layout, field); + end +end + +local generated_form; + +function update_form() + local new_form = form_layout:form(server_info_config, "result"); + if generated_form then + module:remove_item("extension", generated_form); + end + generated_form = new_form; + module:add_item("extension", generated_form); +end + +function add_fields(event) + local fields = event.item; + for _, field in ipairs(fields) do + table.insert(form_layout, field); + end + update_form(); +end + +function remove_fields(event) + local removed_fields = event.item; + for _, removed_field in ipairs(removed_fields) do + local removed_var = removed_field.var or removed_field.name; + for i, field in ipairs(form_layout) do + local var = field.var or field.name + if var == removed_var then + table.remove(form_layout, i); + break; + end + end + end + update_form(); +end + +module:handle_items("server-info-fields", add_fields, remove_fields); + +function module.load() + update_form(); +end -- cgit v1.2.3
