SVGHMI: Add a simple i18n test

SVGHMI: Prevent Dropdown widget to mak exception whe value out of range

SVGHMI: removed dead code

SVGHMI: Add "lang" permament persistent HMI_LOCAL variable to reflect selected language, apply stored language choice at startup and make it always subscribed to a pseudo widget (as for hearbeat) that apply language choice when it changes.

SVGHMI: Added HMI:VarInitPersistent to initialize persistent HMI_LOCAL and PAGE_LOCAL variables, stored as cookies in browser.

SVGHMI: Enforce formating HMI_LOCAL and PAGE_LOCAL variables until the end of variable name

SVGHMI: generate JS translation literals so that it is possible to also translate uses of texts, and added JS code that apply translations to tspans

SVGHMI: widget activable elements : moved code to wher it belongs, rewrote cleaner

SVGHMI: update generated XSLT

Merged

SVGHMI: make a copy of tests/svghmi as test/svghmi_widget because too crowded since having pages for widget documentation. Strip those pages from tests/svghmi, so that it
is more light for regular testing.

SVGHMI: Prevent excluded widget to appear in generated pages' widget list.

SVGHMI: Remove recursive walk in parsed widget to find unique type and use xsl:key instead.

SVGHMI: Fix browser side exception when some widget are not used, and are then discarded and not present in final SVG. In that case JS code was still making reference to discarded widget elements and was raising exception at init.

SVGHMI : removed support for changing keyboard position and showing at user defined location. Feature was problematic in many respect.

SVGHMI: Make an error when pages are nested

SVGHMI: i18n: finished passing back translated messaged to xslt proc, finished template to generate corresponding javascript literals.

SVGHMI: i18n: various fixes about unicode encoding and converting translation result back to XML to feed xslt processor

SVGHMI: i18n: better warning messages, more explicit.

SVGHMI: i18n: now loads PO filesand match translation against catalog. Refactored a bit to move i18n related code in i18n.py

SVGHMI: still WIP, now POT file is properly generated with utf-8 encoding and POEdit is launched when pressing button.

Docutil : reworked Inkscape launching and path resolution in docsvg.py

merge

Removed harmful assert in ProcessLogger.

ProcessLogger was having an assert in constructor when missing logger, leading to systematic exception when testing options accepted by compiler. This exception was silenced in ProjectController, and then MatIEC was always called without options.

SVGHMI: Intermediate commit while implementing i18n. WIP.

SVGHMI: Jump widget: switch to class based declaraion, and add some TODO comments to prepare for jump to relative page being selected through a DropDown widget.

SVGHMI: intermediate state of test/svghmi's SVG for backup... WIP

SVGHMI: CircularBar: use animate() + cormetic changes

SVGHMI: Meter widget: use animate() + cosmetic changes

SVGHMI: Update generated xslt

SVGHMI: Fix bug in keypad leading to error messages in browser console when keypas has no Shift or CapsLock keys

SVGHMI: cosmetic changes

SVGHMI: Input widget overrides undershot() and overshot() methods to display "min: xxx" or "max: xxx" when user input goes out of given range.

SVGHMI: Added clipping to min and max value for all widget using @path,min,max syntax. Added overshot() and undershot() methods to widget base class, called when value is limited to max or min respectively.

SVGHMI: decoupled operation string evaluation from HMI variable uptdate in change_hmi_variable(), paving the way for min/max boundaries enforcement

SVGHMI: Added parsing of min and max value that can be given as @path,min,max in widget description

Merged default in svghmi branch

WebInterface: better wording for wiping PLC content: "Repair"

SVGHMI: almost rewrote Input widget to make it new class based style.

runtime: added restart/reset button in web settings. Accidentaly fixed web settings logging feature.

SVGHMI: added dropdown selection highlighting and fixed scrolling so that it doesn't miss any entry while jumping from one page to the other.

SVGHMI: change scroll buttons into single unicode triangle and center them. Use highlight rectangle duplicated and hidden to catch selection clicks so that the whole row is clickable.

SVGHMI: DropDown widget now using new class based style

Add a little test to see OnChange's .count .first .last in action

Fixed "Onchange" object added in previous commit

Python Safe Globals now have more reliable triggering of OnChange call. Added "Onchange" object to accessible runtime variables that let user python code see count of changes and first and last values.

SVGHMI: cosmetic fixes in button widget

SVGHMI: Rewrote button widget.

SVGHMI: update generated XSLT

SVGHMI: stuff test so that it moves all the time, to have better chance to spot memory leaks...

SVGHMI: prevent unwnted context menu and pinch zoom

SVGHMI: more attempts to prevent losing memory in JS closure

SVGHMI: WIP trying to reduce memory usage : use .onclick onstead of SetAttribute, avoid useless closure and object creation when possible, etc.

SVGHMI: update generated xslt file

SVGHMI: use const when applicable

SVGHMI: prevents text and svg elements selection on the whole page when dragging.

SVGHMI: Update default test to check that Input widget is indeed updated when variable changes.

SVGHMI: Fix: on screen keyboard wasn't showing up when editing local variables through Input widget.

Project tree: avoid flickering and glitches in notebook when selecting some still not opened ConfigTreeNode

merge

py_ext: better handling of coma separated OnChange attribute for python safe global variables.

Project tree: Clicking on ConfigTreeNode should have same behaviour as for POUS and other IEC types : simple click to select and double click to open.

Allow customization of generated py_ext OnChange calls, by adding a static method to PythonFileCTNMixin that can the be later hot patched.

Arbitrary variables added to JsonTable subscription are now passed as 'extra' field in json query. As an example added JsonTable filtering in tests/svghmi
