This hook allows the plugin to create the serial port object (or pass to
the next hook or the builtin serial port handler) which allows for
serial communication filtering or a different communication transport.
Use @foosel's code to use the same loop for hooks as well as the
builtin.
Having to wait for the first serial timeout before sending the first M105 even when not waiting for seeing a "start" caused unnecessary wait times for reaching the "Operational" state.
Add computed property "name" to function objects if not provided by the
browser, to avoid dropping out of main.js before it is finished.
(cherry picked from commit 68215c6)
Tracking the "ok" attached to a resend is necessary in order to make sure that it does not trigger the resend of the next line after the requested one right after, causing resend loops in some cases, e.g. "> 100", "> 101" , "< rs 100", "ok", "> 100", "< expected 100, got 101, rs 100" -- here the last error from the firmware could not be processed as "false negative" correctly (101 was already sent to the printer when it detected the error for 100, so this error just needs to be ignored) since the resend flag was already cleared due to line 100 and 101 having been enqueued, 100 in the resend handler, 101 due to the following ok. This patch fixes the latter, thus solving the problem.
Plugins may be enabled and disabled during runtime. If they are of types which allow hot loading, this will be done. Otherwise they will be marked as pending and updated after a restart. Same for installation and uninstallation.
Plugins may be loaded, unloaded, activated and deactivated. Errors while trying to load a plugin or initializing an implementation will only result in it staying deactive but registered in the system, allowing it to be further processed e.g. by a plugin manager
Can be used to always retrieve the defaults (by providing an empty config dict) or to utilize the get method with other settings than the system settings.
Multiple mixins are allowed of course. Allowing multiple implementations lead to too many problems due to plugin names for referring to the APIs of SimpleApiPlugins or the assets of AssetPlugins.
Hence __plugin_implementations__ has been deprecated in favor of __plugin_implementation__. The plugin subsystem will automatically copy the first implementation from __plugin_implementations__ to __plugin_implementation__ and log a deprecation warning.
Adjusted documentation accordingly. Also added docs for helpers.
Detected plugins are now logged in a better readable way and with additional information.
Also marked folder for bundled plugins as bundled - forgot to do that earlier.
This way user adjustments to those timeouts via the settings
will take immediate effect even while the connection to the
printer is already established.
