Moved twisted/nevow/athena away from Berermiz_service.py + some minor cleanup

Added Beremiz_service.py command line switch to load python extention for runtime independently from PLC program

py_ext user python code can now know about global variables shared with PLC. updated tests/python accordingly

Fixed python runtime trace thread auto suspend. Now suspends after 3 seconds when no trace is requested

Added runtime side trace buffer, handled in a separate thread, limited to 1MB, and dropped after 3 seconds if not used by IDE. GetTraceVariables is not anymore blocking on next PLC cycle

Moved trace buffer unpacking in the IDE. Latest traced variable samples are now passed as a single string

Optimized plc_debug.c generated code. Should produce smaller code size. Added statically initialized array for PLC tracable variable description.

more minor cleanup

minor cleanup

merged forgotten changes

Simplified use of runtime's global variable __common_ticktime accross extensions.

Use '-p' command line option when running matiec (iec2c)

Add command line option '-l' when calling matiec

Fixed location of directory containing IEC standard library in C format.

Change location of directory containing IEC standard library in C format.

Added highlighting of wrong SINGLE task trigger

Fixed incomplete task grid update on interface change, in Resource editor

Enable overloading of availables languages in POU creation dialog

Enable overloading of task triggerring source cell editor (SINGLE) in resource editor. PLCGenerator now generates MULTI keywork instead of SINGLE when task's activation is surroundes with square brackets

Updated tests/python : added derivated return type function declaration+call and re-enabled refrences to global FB interfaces

Fixed declaration and ST code gen for IEC function that return derivated types

Added a variable name text entry dialog to allow name change on drag'n'drops

'NamedConstant' variable D'n'D is now allowed on variable grid

Allow specification of command line arguments encoding in ProcessLogger

Splitted type selection menu code in VariablePanel, making easier to override behaviour by inheritence

Fixed crash at project load when features.libraries is empty (i.e. no libraries are provided).

Added plcopen.definitions.DefaultType, set to INT.

Fixed POU paste exception

Propagated changes made in matiec/lib/accessor.h _SET_VAR macro (Mario's matiec changes merged at 39086e324665) to py_ext library, and other (not compiled in) XML standard FB definitions.

Added 'NamedConstant' drag'n'drop in text programs as well (was only accepted on graphical languages).

Fixed launch of PLCopenEditor, broken since 611fded24ce4.

Organized controller's _Build sub-methods layout. Many (unwanted) white space changes.

Added 'NamedConstant' drag'n'drop in programs. It does create a simple variable with initial value and is usefull for drag'n'drop constants from extensions while keeping a name associated with constant

xmlclass : Ensured precedence of newly defined class in case of conflicting declaration

Fixed Exception dialog crash when original exception contains unicode

Fixed unused variable in plc_debug.c

On windows, prepend CWD to PATH before invoking Generic target make command

Pair with matiec a51a3bb4d613. Re-enable resource add/remove, updated CFLAGS, disabled broken global FG test in tests/python

Fixed typo in plcopen.py

Changed python_gear ratio type from USINT to UINT, less restrictive regarding range

Fixed support for spaces in matiec libraries path with native beremiz build

Delayed CANopen initialization for better busoff recovery

Fixed non initialized timer causing exception in some rare cases (continued)

Fixed non initialized timer causing exception in some rare cases

Fix matplotlib exception when launching on XP

Fixed import error when loading extensions

More gcc warning avoided

Added <string.h> to plc_main_head.c to avoid warnings.

Tidy PLCopen definitions

Removed depricated matiec stdlib-code-generator-generator

Factorized bitmap and i18n resources loading in between PLCopenEditor and Beremiz. Now in utils/misc.py

Re-introduced toolchain_makefile.py. This time, it comes with a 'Generic' target, and a 'genericmake' example

Removed dead code

Fixed xmlclass bug when enabling/disabling libraries in root CTN

RC5

Added example of SFC simulating traffic lights

Fixed bugs in SFC when loading transition condition and referenced transition or action body

Fixed bug with edge and storage parameters in contact and coil not loaded in file saved with older version

Fixed bug when defining variable type as explicit array in VariablePanel

Fixed bug with function POU when extracting return type
