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

SVGHMI: Ensure that when a HMI:List is refered, none of its refered elements are discarded.

Backed out changeset b2ba6eeb61ec. Users reported text styling being messed in some cases.

Runtime: Added PostStart methot to PLCObject, called after PLC is started, with all libraries and python object already created, and python extensions "Start" methods being called.
This is called before python thread processing py_eval blocks starts. Example purpose: attach additional ressource to web services

SVGHMI: Add generic action buttons to JSON table, with an example in tests/svghmi: wipe alar list.

SVGHMI: do not do XSLT transform if both SVGHMI and HMI Tree didn't change since last build

Merged

SVGHMI: Make ScrollBar's variables order match JsonTable's variables order to avoid confusion

SVGHMI: Lighter display of HMI Tree, no more icons and use buttons. Auto expand root. Fix loading of HMI tree XML backup (hmiclass attribute wasn't kept).

SVGHMI: Systematically save HMI Tree in build directory as hmitree.xml when building, so that HMI Tree can be displayed when re-opening project, without having to build

SVGHMI: attempt to prevent crazy styling with HMI:TextStyleList when inkscape store style in tspan instead of text element.

IDE: Fix logging of external process execution time so that it is visible on windows as well.

IDE: Process Logging : Add annotation in log so that user can see build is still alive and how long external process takes.

IDE: Iec2CSettings: Log wasn't available in case of exception when launching iec2c.

IDE: Log: Cosmetic changes, refactoring

SVGHMI: Make build log less redundant, and refactor progress information code a bit, to make it also a bit less redundant.

IDE: Make ST code generation more verbose, since it can be really long in case of big programs, and it is better to let the user know build is still in progress.

merged

SVGHMI: Fixed progress time computation

IDE: Fixed log console that was not updating line by line smoothly when building.

SVGHMI: Optimized overlapping geometry (widget ot page belonging) computation. Added human readable messages for progress. Includes updated XSLT.

merged

Merge changes from default into svghmi branch

SVGHMI: More build time optimization : def_by_label now takes far less time.

SVGHMI: Optimize sumarized_elements xslt function, taking most of SVGHMI build time.

Merge

SVGHMI: Add icons

SVGHMI: Fixed/extended error message when failing to launch POEdit.

SVGHMI: Fix launch of POEdit on widows. Parsing oommand in registry based on heuristic was bad, now using regex should be safer. TODO : replicate for Inkscape launch.

SVGHMI: display progress in IDE console while building

SVGHMI: finally found why HMI:Input wasnt't initializing properly: vsprintf takes a list. Also, removed intermediate variable last_val, since edit_value() works on strings anyhow, and in case of formated floats, it is better to workl on already formated value.

SVGHMI: update generated XSLT

Allow printf-like formating in HMI:Input, usefull for example when dealing with floating point numbers.

SVGHMI: Switch from {object} to Map for "updates" global, for performance but also preventing wierd behaviour when iterating

SVGHMI: Fixed HMI:ScrollBar to exclude cursor size from accessible range ( position is now 0->range-size instead of 0->range ). Fixed and extended tests/svghmi to have working ScrollBar on two alarm pages. Includes generated XSLT update.

SVGHMI: JsonTable removed useless promise since fetch() already does one. Updated generated XSLT.

SVGHMI: Optimization for JsonTable : reload JSON only when necessary, and avoid concurrent http requests.

merge

SVGHMI: update generated XSLT

SVGHMI: little fix ihn i18n example.

SVGHMI: Fixed sending HMI_REAL to PLC. Added a svghmi_real test that illustrates using printf style formating in HMI:Display to control precision of Float number display.

SVGHMI: i18n: ensure langs always appea in same order, and add two variables that are updated automatically when selecting a new language : lang_name and lang_code. Also fixed i18n startup, prevent wrong lang numer to crash loading.

SVGHMI: more straightforward implementation of dragging position computation in Scrollbar + some little fix about boundaries.
