Tests: fix project edit test sikuli IDE test.

Background click based on bitmap matching doesn't work.
Grid dots are not good match candidates.
Rendering probably affected by virtual display's bpp or rasterizer approximations.

runtime, retain: remove forgotten debug code.

Runtime: removing dead code

IDE: removed one (last ?) wx.NewId() that was called on each opening of project tree popup menu

Tests: Re-introduced pytest based tests. Fixed them a bit, commented-out otherwise. Application tests only runs with logging test, and PLCOpenEditor tests seem broken.

Tests: Enhance robustness of stdout driven waiting state in Sikuli based tests.

Some tests were randomly passing, because from time to time waiting for idle was skiped. It was combination of multiple problems :
- buffering on stdout (now use readline + flush for each write to log)
- it is sometime required to wait for activity before waiting for timeout added "WaitForChangeAndIdle" to "stdoutIdleObserver"

Tests: add an IDE test that relies on image matching.

Tests: re-introduce xvfb+x11vnc target in Makefile : xvfb_sikuli

Fix sequel of wxPython 4 port : double click on tab wasn't maximizing and was showing exception.

Tests: Makefile's PIPESTATUS turned into small letters (wrong vim shortcut ?) leading to always passing tests.

Tests: Various enhancements in Makefile and sikuli common python code.

Tests: Added BEREMIZPYTHONPATH to point to Python interpreter to use for tests.

Documentation/comment fix.

IDE: Fix one more sequel of wxPython4 port : typo in editors/TextViewer.py

Tests: Add a Makefile variable to allow changing standalone headless X server command (Xvfb by default)

Merge default head that was only merged in wxPython4

merged default

Add Docker image definition as reference platform to run IDE tests.

Tests: added tests/Makefile and a first test in tests/ide_tests. Test requires sikuli and Xvfb or Xnest.

IDE: Add -l or --log command line parameter to give a file where all content witten to console window will be appended. File can be /dev/stdout.

Merge default

IDE: follow-up on change in 83ed4ea362db - added workaround when matiec generated files contain unexpected characters.

Runtime : force using monotonic time in Timer (threading). Prevent watchdog to trigger when changing system time.

SVGHMI: remove debug code

SVGHMI: update generated XSLT

SVGHMI: fix again appication of frequency value when given in label. Use it on PushButton instance in svghmi test.

TESTS: moved non-automated tests Beremiz projects stored as directories in /tests to new directory /tests/projects

Create README.md in tests

SVGHMI: update generated xslt, and svghmi test project files

SVGHMI: Add pushbutton widget, that can take reflect short press in variable, but has no garantee on consistency.

SVGHMI: Fixed support for frequency parsing in widget label

Merge

SVGHMI: update generated xslt

SVGHMI test: add special commandline to launch chromium as new intependent window, without GPU acceleration.

SVGHMI: add syntax for widget update frequency in widget label: HMI:WidgetType|freq:arg0:arg1@path

OPC-UA client: "static" class was forgotten for open62541 client structure preventing multiple client.

OPC-UA: cosmetic fix and armless typo

Merged default in wxPython4, include runtimeLists

Merge

SVGHMI: added ListSwitch widget

Merged RuntimeLists branch

Close RuntimeLists branch

Fix bug introduced in previous commit : dual link list wasn't append and remove wasn't implemented correctly. Removed debug code, enhanced variable names and comments.

SVGHMI: optimization of C part : stop traversing the whole HMI tree, use dual linked list for subscriptions and single linked list for changes from HMI. Intermediate commit, still crashing in some cases.

Xenomai runtime: ensure that __DEBUG global variable is set when resuming debug.

SVGHMI: Adapt svghmi.c to changes in UnpackVar

Runtime: Now retain uses a list based on data available in VARIABLES.csv instead of traversing the whole instance tree looking for RETAIN flag.

RUNTIME: Variable forcing now uses limited list and buffer instead of systematical instance tree traversal and in-tree "fvalue" to keep track of forced value for pointed variables (external, located). Pointer swapping is performed when forcing externals and located, with backup being restored when forcing is reset. Retain still uses tree traversal.

RUNTIME: Variable trace now uses limited list and buffer instead of flags in instance tree that was requiring systematical instance tree traversal, and worst size buffer. Forcing and retain still use tree traversal.

SVGHMI: more accurate filtering of elements to unlink or not

OPC-UA client: generated code now take UA_Variants on the stack directly, avoid useless allocation on write, and unalloc implicitely allocated data on read

OPC-UA client: generated code now take UA_Variants on the stack directly, avoid useless allocation on write, and unalloc implicitely allocated data on read

IDE: Tutorial/Example menu was broken : path of project being open was the same for all menu entries.

IDE: Tutorial/Example menu was broken, probably after a merge. Menu (and corresponding code) was duplicated. Also, path of project beeing open was the same for all menu entries.

Fix bug when updating data in variable panel.

Grid event naming CHANGE->CHANGING was wrong. CHANGE->CHANGED is the way to go.

SVGHMI: update tests/evghmi to reflect/test latest changes. update generated XSLT.

SVGHMI: multiple non significant changes: doc fixes, modern style access to attributes, enforce double quotes around member name in object literals.

SVGHMI: Changes /CURRENT_PAGE_* behaviour to prevent problem whith multiclient : all clients were switching page when one was jumping.
- now PLC have to prefix page name with "!" to order page switch.
- HMI do not prefix with "!" when jumping, this avoiding looping incidently
- In case of multiple client:
CURRENT_PAGE reflects current page of last client hwo did jump
Setting CURRENT_PAGE with "!" affects all clients simultaneously

SVGHMI: changes that should fix some corner cases about unlinking and discardable element that still didn't show until now.
- list that would have been declared in some groups could have been discarded.
- elements to be unlinked were comuted based on filtering $hmi_elements, whereas $hmi_widget already filtered list

SVGHMI: update generated XSLT

merged

SVGHMI: add CURRENT_PAGE_{location} global variable to reflect currently visible page. If PLC wites some valid page reference in that variable, it triggers page switch. Additionally, fixed /HEARTBEAT being subscribed systematically by JS code even when wtchdog is not enabled.

Follow-up on 83ed4ea362db 'IDE: prevent invoking matiec when IEC code did not change since last build' : build unconditionally after clean

SVGHMI: update test/svghmi to reflect latest changes

SVGHMI: Update generated xslt

SVGHMI: remove "value" element in meter and circularbar widget. Adding support for printf like formating make widget label too heavy. It is better to use Display widget instead.

Workaround RubberBand drawing problem on GTK3

Depricated PyGridCellEditor becomes GridCellEditor

Fix exception when canvas becomes null because of window resize, and avoid useless parameter+condition in GetLogicalDC

Preliminary support for WxPython 4.1.0. Needs more testing. Grid selection/focus seems broken, and probably many other bugs hidden in dialogs and editors.

Merge SVGHMI in default

Close SVGHMI branch

Copy description when DnD variables from Globals in resources and configuration variable panels to POUs. Also prevent making exception in case some other DropSource wouldn't provide description.

IDE: Add a "undo" button for each field in CTN config panel to reset to default value.

SVGHMI: detect watchdog abuse (more than one HMI instance with watchdog) at build time

SVGHMI: code refactoring allowing more in depth customization for substitution on start/stop/restart commands, and default SVG choice.

Runtime: more robust loading of Wamp config, specially in case config file was corrupted.

SVGHMI: add arguments to pass to ressource factory when attaching rerssource to svghmi root

SVGHMI: fix typo in slider widget

Runtime: Handle errors in user's python code more gracefully : make exceptions and allow repair.

SVGHMI: Fixed halting problem when there is no session opened.

SVGHMI: Widget lib: small doc fix.

SVGHMI: DnD UI: Use widget's short description, initially forgoten.

SVGHMI: Fixed typo on session manager unregister, leading to wrong count of sessions and then exceptions when creating more session than allowed in protocol options. Also added more safety check in protocol in case session would be missing.

SVGHMI: set some boundaries for watchdog timings and max connection count.

SVGHMI: update generated xslt

SVGHMI: fixed bug introduced in 7bdb766c2a4d, typo breaking meter widget

SVGHMI: default library path, default page when starting a SVGHMI project, error page when no SVG present

SVGHMI: finished multiclient support. Still needs more testing.

SVGHMI: Fixing last commit's multiclient implementation, in case of watchdog. To be continued, since multiclient still fail...

SVGHMI: Implemented multiserver+multiclient, but only tested with single client and single server for now. To be continued...

SVGHMI: More configuration parameters : network interface, TCP port, URL path and watchdog enabling.

SVGHMI: Added a way to distinguish watchdog-enabled HMI from multi-client HMI in URL.

SVGHMI: Prepare accepting multiple clients on multiple HMI: Use POULibrary new capability to add variables to PLC Configuration. Now heartbeat and HMI tree root are added by the library part of SVGHMI, and not by each instance.

IDE: Allow POU Libraries to inject PLC Configurations globals during build.

SVGHMI: DnD UI: Add hint instructing user to Drag HMI tree items to text field.

SVGHMI: update generated XSLT files

removed useless import

SVGHMI: DnD UI: SVG for DnD now generated again based on paths and args entries filled by user.

merge

SVGHMI: UI: added prefill of arguments according to values in widget instance in library. Also added library's widget instance description to description field.

IDE: Fixed variable traces graphs RingBuffers. Removed an apparently useless wxCallAfter in trend graph that was leading to pydeadobject exception on wxGTK when double-clicking.

IDE: Cleaned up some useless tests in variable trace data handling code, changed from bare numpy arrays to RingBuffers inorder to avoid RAM outage and crash after long tracing session.

IDE: Log: Prevent crash when display progress on empty log.

merge

Copy description when DnD variables from CodeFile CTN to POUs

SVGHMI: Fixed typo in last commit

merged

Runtime: Fix exception "Worker is disabled" when connecting while PLC runtime is starting.

Pyro/wamp/UI delegate jobs to Worker, causing race condition if worker isn't already started.
Added a function to ensure that Worker is already created when pyro or UI starts

SVGHMI: UI now have multiple HMI tree variables DnD to widget paths. Still no type checking, WIP.

Finished fixing Wx IDs abuse. There was still some wasted IDs because of wx.NewId calls in many places where it wasn't needed, and those IDs were not re-used. As a consequence Beremiz was making exception crashing after a few hours of intensive use.

SVGHMI: DnD UI : changed layout again, moved description in a vertical splitter, added scrollbar for preview and signature, fixed flickering description

SVGHMI: UI: Swap widget selection tree and preview panel

SVGHMI: WIP: Widget Library UI: Reworking widget selection and binding.

Merged SVGHMI branches

SVGHMI: WIP on Widget DnD UI : Added documentation to widgets, that is injected in widget parse tree during widget analysis

SVGHMI: Fix behaviour of Jump widget, that wasn't displaying "disabled" state in some cases.

merged default in svghmi

SVGHMI: updating generated XSLT

SVGHMI: Intermediate state while updating UI, preparing for displaying widget description and multiple variables selections

SVGHMI: Extend widget labels parsing to allow expressing widget's accepted types in labels

SVGHMI: Add analyse_widget stylesheet and python code to execute it, in order to obtain widget signature independently of DnD SVG file generation.

SVGHMI: drop useless code from gen_dnd_widget.yslt2, renamed python callback to pass messages

SVGHMI: Added widget_desc to declare widget signature and description

SVGHMI: In order to allow widget signature and description to coexist in same ysl2 file, introduced widget_class, widget_defs to declare widget codegen templates and gen_index_xhtml to mark templates that are only usefull in gen_index_xhtml.xslt.

SVGHMI: keep track of order of selection in HMI tree, so that variable can be passed in same order to DnD widget

SVGHMI: fixed typo

SVGHMI: still quite naive path substitution whn prepearing widget for DnD, but now uses label generation.

Multiple widget DnD and mutiple variable still make no sense because all path are replaced with same path, but atleast min/max value are preserved...

SVGHMI: Added text box for tranformation feedback aside widget mignature

Merged default in SVGHMI

SVGHMI: prototype of widget interface description using SVG's desc field, added to SVGHMI's internal svg widget library.

SVGHMI: Naive implementation of widget path substitution in widget DnD: considers widget always have only one variable, and no type checking.

SVGHMI: Widget transform before DnD now have HMI path as a parameter

SVGHMI: Widget transform before DnD now should have HMI path as a parameter, but this path isn't computed for some reason... WIP.

SVGHMI: Widget DnD to Inkscape : Added source SVG widget label parsing and pass selecte HMI subtree to XSLT tranform, so that SVG containing multiple widgets can later be matched against hmi tree fragments, in order to DnD complex groups of widgets.

SVGHMI: Widget Library Picker now transforms SVG widget before allowing DnD. Transform is just identity forn now, but label parsing have already been included. To be continued.

SVGHMI: Ensure that when widgets are nested in HMI:Switch widget, their sub-elements are taken as switch's choice in case their label match the syntax.

SVGHMI: Code cleanup for ToggleButton.

SVGHMI: Fixed last i18n changes meant to allow checking changes in PO files. Was making build exception when no PO files available.

IDE: Add a shortcut to project "Clean" action : F9

merge

SVGHMI: fixed embedded fonts family name not matching when using windows version of inkscape

SVGHMI: force svghmi build if any change in fonts or translation (.PO) files

SVGHMI: Add file type drag'n'drop to widget picker, for now drops widget's original SVG.

SVGHMI: silence debug output in generated xhtml.

SVGHMI: Implemented "Add Font" and "Remove Font", add font embedding in CSS at build time, tested ok with some OTF for now.

SVGHMI: Add font management buttons and icons, doing nothing for now

Fixed misuse of GridCellEditor in DurationCellEditor, potentially leading to crash on windows.

SVGHMI: Fix update of HMI tree in UI when loading from XML at start. Removed some dead code left after split of svghmi.py into svghmi.py+ui.py.

merge

SVGHMI: added "page_node" variable that reflects the HMI tree path of current relative page

SVGHMI: Add list of HMI tree path in a JS array, so that we can use it for multiple purpose :
- display name of edited variable in keypads (currently wrong in relative pages)
- have some variable that hold basename of current relative page HMI_NODE's path
- propose some list of names in DropDown when selecting a relative page to jump to, without having to instancite many jump widgets.

SVGHMI: Fixed wierd CDATA mess in output xhtml, because of backticks copy pasted in some yml ||text block||

SVGHMI: Added fonts.py with functions to convert ttf, otf and woff fonts into data_uri based CSS font-face

merge

SVGHMI: split svghmi.py into svghmi.py (Config Tree Node + code gen) and ui.py (UI for HMI tree and Widget picking)

SVGHMI: stop serving HMI open wide on all interfaces. That was a security hole. It is user/developer responsibity to forward connection with for exemple stunnel and make it securely accessible from LAN.

SVGHMI: Filter unseen geometry from inkscape CSV output.

When inkscape exports geometry form all objects, then it also includes objects from svg:defs. This makes problems when deciding if an object is part of a page, since coordinate of objects in svg:defs can eventualy be contained in a page. In the end, those objects where getting detached when leaving pages where they where found, leading for exemple to non working text on clipping when the clipped text was cloned in multiple page.

SVGHMI: Fix typo in error message formating in i18n.

SVGHMI: split svghmi.py into hmi_tree.py + svghmi.py

Merged

SVGHMI: JsonTable: Fixed options not being passed in JSON post when jumping to a page where additional variables are pre-defined by a HMI:VarInit.
Was JS Fetch Promise not executed late enough, and gathering JsonTable variables before the sequence of calls to dispatch() was finished.

SVGHMI: Added small widget library for library browser testing.

SVGHMI: Added SVG widget library browser. Supports browsing and previewing widgets. Widget validation and drag'n'drop are still to be implemented.

Allow using spin() from ProcessLogger even with no logger given.

merged

SVGHMI: cosmetic change, missing semicolon

SVGHMI: JsonTable should refresh when re-subscibing, because data might have changed while not on the page we are switching to.

SVGHMI: Fixed problems happening when value is higher than maximum or lower than minimum in Input widget. "max" and "min" string was getting into keypad text field, was not diplayed systematically, and was staying forever sometime.

SVGHMI: change default values for JsonTable, leading to scrollbar initialized at annoying non-zero position
