make FindInPouDialog work on Windows with wxPython 2.8

additional fix for changeset 474de7f

fix local search in actions and transitions

convert FindInPouDialog from wx.Frame to wx.Dialog

In this case FindInPouDialog Windows isn't listed in windows manager
on Alt-Tab. And it's not shown on top of other applications. For
example, previously the dialog was shown even on top of web browser or
word processor.

temporary disable SFC transitions in IL, because matiec can't compile it

matiec freezes in this case.
See https://bitbucket.org/mjsousa/matiec/issues/58/iec2c-freezes-if-sfc-transition-is-in-il

fix issue with creating SFC transitions using ST and IL

Beremiz generates text representation for transitions without names.
Therefore transition name in its IL code is not needed.

replace '-' with '.' in resource tab and transition/action SFC code


This makes tab names consistent with the way the same information is shown in variable panel.

check during program generation whether source signal is defined for single task

fix strange behavior on Backspace press in ST

Before:
if text was selected and cursor was at indention, one indention (two
spaces) was removed.

if cursor was at start position of the line, then nothing happened.

if cursor was in the middle of indention then on backspace more
indention were added


Now:
if text is selected, it will be removed.
if cursor is at start position, then new line will be removed.
if cursor was in the middle of indention one indention is removed.

fix close button in system menu for AboutDialog on Windows


If SetEscapeId receives wx.ID_CLOSE as parameter, then on Windows with
wxPython 2.8 system close button in title bar stops working.
If wx.ID_CANCEL or wx.ID_OK is used in SetEscapeId call, then close
button works correctly.

make renames caseinsensitive

fix problem with SFC action/transition rename

Traceback (most recent call last):
File "/home/developer/WorkData/PLC/beremiz/beremiz/IDEFrame.py", line
1636, in OnProjectTreeItemEndEdit
elif new_name.upper() in [name.upper() for name in
self.Controler.GetProjectPouVariableNames(pou_name) if name !=
old_name]:
NameError: global name 'pou_name' is not defined

fix problem that it was impossible to edit SFC jump, if it references non-existent SFC step

remove all corresponding SFC jumps when SFC step is removed (but only in DRIVENDRAWING_MODE)

rename all corresponding SFC jumps when SFC step is renamed (but only in DRIVENDRAWING_MODE)

add check of new project path in Save As
add dialog window if selected directory is the current directory project, or already contains another project

fix issue that in Debug mode LD instance doesn't show correctly its state after
continuation of FBD_Connector.

Previously state signals doesn't propogate through FBD_Connector.

fix issue with task rename if "Name" column label is translated into
other language

fix issue with compiling SFC POU with non-connected transition (type "connection")

fix bug with recent projects menu, remove path to the project from menu, if project directory doesn't exist

fix bug with empty directories in recent projects menu
remove path to a project from recent projects menu, if project directory is empty

fix list of recent projects in File menu, add path to current project after Save As

by default init input and output in step sfc block, and output for initial step sfc block

update PLC status after initialization

This is necessary especially if existed PLC program is loaded, but PLC
is not started automatically. In this case taskbar icon shows that PLC
isn't empty.

always load existing PLC program from the working directory

stop PLC before unloading


This fixes segmentation fault if service was quit without stopping it.
It has happened if Beremiz service was quit using taskbar icon or by
closing Beremiz IDE (in case of autostarted local service).

In second case to trigger the bug following step has to be done:
1. Open Beremiz IDE
2. Open project, compile and connect to LOCAL:// runtime
3. Transfer and start the PLC program
4. Open other project without disconneting the PLC runtime
5. Close Beremiz IDE

add internatialization support for Beremiz_service.py

fix issue with changing annonced Pyro service name via taskbar icon

don't crash on trying to change IP interface for Beremiz_service using taskbar icon if IP wasn't previously


By default IP is not set (None) and service listen only on localhost interface.
