SVGHMI: Add premature implementation of XY chart.

SVGHMI: fix widget's update frequency forcing : syntax checking was enforcing unit and js code was using undefined variables

SVGHMI: fix syntax error in sprintf.js and force makefile to regen xslt files when sprintf.js changes

SVGHMI: fix test/projects/svghmi "unspecified" frequency that was actualy specified...

merge default

Tests: No need to archive test results before uploading them as action artifacts.

Tests: ...

Tests: re-enable running test in github action, now that docker image should be cached.

Tests: temporary disable problematic part, to force action to succeed so caching can happen.

Tests: give test directory when creating container, not when running test.

Tests: fix docker image export for GitHub Action caching.

Tests: More fixes amd enhancments to run tests on Github Actions

Tests: use script rather than alias so that bash doesn't need to be interactive shell with a TTY

Tests: remove -it from docker invocation

Workaround "The input device is not a TTY" error on Github Action.

Create run_tests_in_docker.yml

SVGHMI: Add support for forcing widget update frequency with period longer than a second. As an example, "HMI:Display|10s@/myvar" updates variable every 10 seconds.

SVGHMI: cosmetic fixes + removed dead code

SVGHMI: allow widgets to disable clipping on variables given with min and max. Setting this.clip = false disables clipping.

SVGHMI: allow designating widget's sub-elements as main element child rather than descendant. Names staring with "/" in yslt call to labels() only match direct widget childs.

SVGHMI: add localized Date and Time support to sprintf.js. Use with "%D" or "%2.1D" format style.

Minor changes to README.md

wxPython4 sequels: usual naming problem in grid cell change events, non kw-args to menu.Append and event not being skipped.

Tests: Fix missing <br/> in generated html report.

Tests: add HTML report generation and a workaround to bad exception handling in sikuli.

In case of exception in python code, and since a thread is running
to observe stdout, sikuli was never terminated after an exception.
Unfortunately sys.exepthook doesn't work in that version of jython/sikuli.
Test are now written inside functions witch are passed to run_test to deal
with exception.

Tests: refactored sikuli based test

IDE: Postpone execution of keyboard shortcut commands when given while previous command is still being executed, to prevent CTR/builder jamming.

IDE: in case of unhandled exception, write bug report to given log file, so that test report can have it.

Merged default's changes in wxPython4 branch

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

merged

OPC-UA: fix types in model not being preserved after reload of CSV file, leading to exception when changing selection lists content.

OPC-UA: Removed more "LocalizedText()", this time in selected variable list

IDE: prevent invoking matiec when IEC code did not change since last build.

SVGHMI: prevent systematic rebuild when there are multiple instances of SVGHMI CTN.

SVGHMI: optimize HMI tree handling C code to lower CPU usage when traversing large trees

merged

SVGHMI: prevents watchdog being triggered when SVGHMI is empty.

Backed out changeset c646a1f0fb0b - was on wrong branch

Make OPC-UA client compatible with wxPython3, util wxPython4 branch deserve to be merged

Make OPC-UA client compatible with wxPython3, util wxPython4 branch deserve to be merged

IDE: Enforce wxPython3 menu appending syntax in default branch... (Fixes exception at startup)

OPCUA: fix display names appearing with a "LocalizedText(" prefix when browsing localized server.

OPCUA: Add browsing of variables exposed by client when selecting location from variable panel.

OPCUA client: fix handling of string type Node Identifier

Add OPC-UA simple synchronous client extension.

This extension uses python-opcua to growse server nodes, and generates runtime C code that use open62541.
- python-opcua must be available in python path (i.e. "import opcua" must succeed). Can be installed from pypi with "python2 -m pip install opcua --user" .
- at build time, open62541 is expected to be build in "open62541" directory, aside "beremiz" directory.

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.

SVGHMI: Move sprintf.js out of widget_display.ysl2 since it is used in other widgets as well

Dropped SVGUI, deprecated and replaced by SVGHMI. Transformed traffic_lights exemple so that it uses SVGHMI instead.

SVGHMI: Update generated XSLT (PathSlider widget)

SVGHMI: simplication in ScrollBar widget JS code

SVGHMI: Added PathSlider widget

SVGHMI: update generated xslt (List related changes)

SVGHMI: add files missing in ee9e98c856a : Add TextList widget, add support for TextList in DropDown widget, move List, TextStyleList and TextList widget code in dedicated file with documentation.

SVGHMI: add test for Dropdown using TextList

SVGHMI: Add TextList widget, add support for TextList in DropDown widget, move List, TextStyleList and TextList widget code in dedicated file with documentation.

IDE: Add a "Tutorials and Examples" sub menu to "File" menu to directly open projects in /exemples directory. Move 'python' and 'first_steps' projecvts from /tests to /exemple
