SVGHMI: JsonTable now use intermediate variables again to address JSON data without duplicating code or referencing. Using intermediate variables also alows to check for availability of data and stop evaluating early if data is missing. Finally added complete roundtrip example to illustrate use of JSonTable to display "alarms" collected in python from changes on PLC boolean variables.

SVGHMI: removed debug code forgotten here and there.

SVGHMI: JsonTable now makes meaningfull JSON request : all arguments and variables are passed in.

SVGHMI: Keypad is now keeping Javascript type constency. In other words, if a number was given as initial value, input value will have to convert to number in order to be valid. In case invalid value is entered, initial value is restored.

SVGHMI: Behave when project path include spaces, and make more understandable error in case of problem extracting geometry with inkscape.

SVGHMI: Refactor the way JsonTable generate javascript code to access json data. Now support multiple assignments, used in the case of text to change both content and style on the same element.

SVGHMI: Fix again clone unlinking, and this time add an "original" attribute to track the id of the original object before unlinking.

SVGHMI: Fix svg test file while testing latest JsonTableChanges

SVGHMI: HMI:JsonTable also recognize TextStyleList, but parsing of textContent is still not implemented and style is still not updated.

SVGHMI: Deeper clone unlinking. Was actually not recursive, and clones in clones where not unlinked. Stack successive ids to avoid collisions.

SVGHMI: factorize dispatch calling logic.

SVGHMI: HMI:VarInit:"a string"@a_value : empty widget (i.e. empty svg:group) that initialize content of local variables to value given as first argument.

Merge

SVGHMI: Add more local HMI variable tests in tests/svghmi.

SVGHMI: finished initial implementation of PAGE_LOCAL and HMI_LOCAL variables.

SVGHMI: add a SetPoint to Slider Widget, visible only when operating the slider.

SVGHMI: Update Slider widget so that it doesn't display future value but actual value only.

SVGHMI: provide request_animate() to Widget authors so that they can register redraw code when events lead to redraw. Widget member animate() is called when it is time to update DOM.

Merge

SVGHMI: Intermediate state while implementing local HMI variables. Now write to cache only (no send), still need to implement dispatch on change.

Beremiz test project with newly created widgets.

Rebuilded gen_index_html.xslt after all new widgets were commited

Create new multistate widget which extand class widget

Create new CircularSlider widget which extand class widget

Create new slider widget which extand class widget

Reworked togglebutton widget to extand class widget

Changed keyboard to show on defined position.

* svghmi.js
added size paramter to edit_value
changed show_modal function to offset keyboard if paramter passed

*widget_input.ysl2
in on_edit_click:
function get position if key_pos element is defined in input widget

*widget_keypad.ysl2
Reworked keypad widget to extand class widget,
added support for changing keyboard position to user defined location

Reworked button widget so it uses classes.

SVGHMI: allow multiple variables and formatting in Display widget. Formatting is printf style and given as first argument. If no formating is given as widget argument, space separated.

SVGHMI : have to move some JS declarations from "preamble" to "declarations" and others from "declarations" to "definitions" section to make room for JS libraries that would be used by widget classes.

SVGHMI: JS refactoring continued : "dispatch_value_to_widget" becomes widget class member "new_hmi_value" (was also broken by previous relativeness commit)

SVGHMI: widgets are not anymore binary relative or absolute, but have a "relativeness".

Because of allowing multiple variables per widget, we must distinguish if individual variables is relative to page, not the whole widget.

SVGHMI: More JS code refactoring : change_hmi_value and apply_hmi_value now methods of widget class.

SVGHMI: Better JS code semantic in ForEach widget class. Update lagging generated xslt.

SVGHMI: Add ForEach Widget is svghmi test

SVGHMI: add get_idx(index) to widget objects to factorize a bit code repeated accross widgets. To be continued.

SVGHMI: prefer apply_hmi_value() to change_hmi_value() when possible

SVGHMI: Add RelativePages to tests

SVGHMI: Update Widget Display templates to generate Class based declaration.

SVGHMI: JsonTable now picks items from HMI:List, and update texts, all according to Json data. Still miss scrolling.

SVGHMI: JsonTable now generate working data access code for data/* elements.

SVGHMI: Minimal support for HMI:List : clones pointing to elements of any HMI:List are never unlinked, widgets using HMI:List will rely on this.

SVGHMI: minimal JSON Table Widget communication infra + corresponding python code as py_ext code in svghmi test. To be continued.

Python Runtime: order of execution of extension's init() and cleanup() now reflects order of appearance of extensions in configuration tree.

Python Runtime : stil untested optimization of Python Safe Globals.

Now only one python_poll block per python extension is used to trigger
execution of OnChange calls.

Prevent global python_poll blocks to be created when accidentally adding content to C-File OnChange column.

Merge from default

Modbus: fix strange side effect of re-use of condition variables or mutex with Xenomai : without bzero of the associated types, mutex keeps locked.

Modbus: fix client timer invalid arguments.

Modbus add a timer thread, and switch timer to SIGEV_THREAD_ID to follow xenomai posix skin restrictions.

Runtime: Fix typo in PLCObject leading to exception when reporting failure.

SVGHMI: Fix bug introduced when merging default

SVGHMI: Add use of Python PLC Globals it test

Merge default changes in SVGHMI

Merge default changes in SVGHMI

SVGHMI: add "unsubscribable" property to widgets in order to generalize what already happens for jump buttons.
In most cases jump buttons do not really subscribe to pointed HMI variable, path is given as a relative page jump path. When widget.unsubscribable is set to true, no subscription is made on page switch, but still offset is updated.
This fixes bug happening on relative jump buttons without "disabled" element where offset did not change on relative page switch.

SVGHMI: Added widget toggleButton.

SVGHMI: Changed widget button handler to element attribute.

Runtime: create .md5 file at the end of all transfered files being written to disk, so that it presence indicates completeness of transfer.

IDE: Main toolbar : Show repair button also in stop mode. Move repair button after disconnect button.

Runtime: fsync() files when transfering them, to prebent data loss when poweroff soon after programming. Fixed variable naming as a side effect.

PLCObject : reorganize code in StartPLC(), add a PreStartPLC() empty method, to be overloaded by runtime extensions.

Solve import order problem when POULibrary imports ConfigTreeNode because of UserAddressedException. Now UserAddressedException is declared in POULibrary.py, as a quick and dirty fix, but some independant module should be created for beremiz exceptions in general.

SVGHMI: stop using eval in change_hmi_value, apparently slowly leaking memory.

SVGHMI: Switch widget was picking sub-elements from original SVG, not the result SVG ehwe clones are unlinked, thus making problems with svg:use based widgets.

SVGHMI: When unlinking a clone of a group, do not create additional group, but merge transformation and styles, and replace label. This allows svg:use based widgets to directly access elements of svg:use targeted element.

SVGHMI: Applies clone unlinking to widget themselves, not only to clones inside widgets.

merge

SVGHMI: Makes error when HMI tree is not well formed. Prevents multiple and non-first HMI_NODE, and ensure that all paths in HMI tree are unique.

Added FatalError call to Libraries code gen, so that they can emit messages addressed like config tree nodes do.

SVGHMI: more Widget properties declared ES6 style.

SVGHMI: Switch widget now use class declaration

SVGHMI: Update Button widget to class declaration, and add a button widget in tests/svghmi.

SVGHMI: explicit handling of undefined maximum widget update frequency

SVGHMI: removed dead code

SVGHMI: Back button updated to class style

merge

DEBUG: (IDE side) fixed wrong implementation of anti-rapid-fire leading to systematic delay in subscribing

SVGHMI: Exclude non-widget HMI:* labeled elements from hmi_widget. Namely : HMI:Page HMI:Lang and HMI:List have been excluded.

SVGHMI: clean up dead code, update generated xslt.

SVGHMI: apply per class overloading of sub/unsub to Jump widget

SVGHMI: apply per class overloading of sub/unsub to ForEach widget

SVGHMI: Widget's specific sub/unsub traits are now wxpressed in widget's class.

SVGHMI: Parameters common to all widget constructors now passed as ordered parameters.

SVGHMI: One class per widget type, widget objects are instances of these classes, and members are passed through constructor. This allows to keep compatible with previous widget_defs template used in most widgets.

SVGHMI: Add an exslt function to collect used widget types, in order to only include necessary JS definitions in furure changes.

SVGHMI: Systematically output local name as /* comment */ when emiting content.

Merge

SVGHMI: Fix flawed logic to place nodes in the HMI tree, leading to wrecked tree in some cases.

Added button and circular bar widgets.

SVGHMI: added more meaningful namespaces to emit javascript code from.

SVGHMI: moved JS code of foreach and jump widget in corresponding widget_*.ysl2. To be continued.

SVGHMI: spread JS code from svghmi/scripts.ysl2 in other .ysl2 files, using dedicated preamble and epilogue namespaces
