Config Mode
===========
As of 2014.4 `gluon-config-mode` consists of several modules.
gluon-config-mode-core
This modules provides the core functionality for the config mode.
All modules must depend on it.
gluon-config-mode-hostname
Provides a hostname field.
gluon-config-mode-autoupdater
Informs whether the autoupdater is enabled.
gluon-config-mode-mesh-vpn
Allows toggling of mesh-vpn-fastd and setting a bandwidth limit.
gluon-config-mode-geo-location
Enables the user to set the geographical location of the node.
gluon-config-mode-contact-info
Adds a field where the user can provide contact information.
In order to get a config mode close to the one found in 2014.3.x you may add
these modules to your `site.mk`:
gluon-config-mode-hostname,
gluon-config-mode-autoupdater,
gluon-config-mode-mesh-vpn,
gluon-config-mode-geo-location,
gluon-config-mode-contact-info
Writing Config Mode Modules
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Config mode modules are located at `/lib/gluon/config-mode/wizard` and
`/lib/gluon/config-mode/reboot`. Modules are named like `0000-name.lua` and
are executed in lexical order. If you take the standard set of modules, the
order is, for wizard modules:
- 0050-autoupdater-info
- 0100-hostname
- 0300-mesh-vpn
- 0400-geo-location
- 0500-contact-info
While for reboot modules it is:
- 0100-mesh-vpn
- 0900-msg-reboot
Wizards
-------
Wizard modules return a UCI section. A simple module capable of changing the
hostname might look like this::
local cbi = require "luci.cbi"
local uci = luci.model.uci.cursor()
local M = {}
function M.section(form)
local s = form:section(cbi.SimpleSection, nil, nil)
local o = s:option(cbi.Value, "_hostname", "Hostname")
o.value = uci:get_first("system", "system", "hostname")
o.rmempty = false
o.datatype = "hostname"
end
function M.handle(data)
uci:set("system", uci:get_first("system", "system"), "hostname", data._hostname)
uci:save("system")
uci:commit("system")
end
return M
Reboot page
-----------
Reboot modules return a function that will be called when the page is to be
rendered or nil (i.e. the module is skipped)::
if no_hello_world_today then
return nil
else
return function ()
luci.template.render_string("Hello World!")
end
end
