Moved some definitions away from controller class, and adaped references them through all code.

Hook Beremiz Launcher AppStart to AdvancedSplash OnPaint event in order to ensure image is beeing displayed before loading.

Avoid endline escaping in multiline xpath epressions in xslt. '
' Is apparently ignored but never know...

Fixed earlier XSLT optimizations. Some/most results were missing.

Moved some code from PLCController.py to other modules. Added necessary imports.

GetPouVariables optimized with XSLTModelQuery

Added /plcopen/InstancesPathCollector.py, to move more model xslt querying code away from PLCController.py.

Fixed Exception dialog disapearing after a view second when exception occurs during app startup.
Problem was caused by splashscreen timeout, wx closing averything else if there is no more main frame.
Changes:
- no more timeout for splashscreen
- use wx.App OnInit method to give first operation to mainloop, object are then now created in mainloop
- main loop is then created _before_ showing splash screen
- no more wxyield or wx processevent tricks needed to display splash screen
- exception handler not blocking anymore on dialog (callafter)
- because of mainloop being there before everything, exit must be called explicitely if exception caught during startup -> exit parameter in handle_exception + try/except around startup calls

UNTESTED ON WINDOWS

Moved XSLTModelQuery class to own module in plcopen package.

Added a class to speedup all XSLT queries. WIP, now only for instances_path.xslt / GetInstanceList()

Stripped useless node creation in instances_path stylesheet.

This should really help GetInstanceList to perform better: resolver removed, no more deepcopy, no more useless xml serialization, no more node-set() calls.

YSLT auto indent trick is useless here, added yslt_noindent.yml2, regenerated XSLT files

Prevent compiling XSLT on each call of GetInstanceList. To be continued. More optimization needed here. 100x would be fine...

Changed meaning of -c commandline argument for Beremiz service : only gives DEFAULT wamp config.
If existing project already has a wamp config, it is taken instead.

Factorized duplicated code

Better variable naming, and small optimization.

Unclutter graphics package scope.
Moved some import statements from "graphics" package to "viewer" module.
It also avoid systematic import of everything in graphics when we only need one submodule.

Removed dead code

Fixed pyro timeout for runtime, was set too short and runtime was disconnecting when building PLC

Ask to stop PLC before transfer if it is running

Factorized some repeated refresh code into a method, to allow customisation.

Launcher : add a debug attribute, instead of BMZ_DBG, so that customization can use it.

Stripped old dead code.

More changes in Launcher. Modules to be loaded in the background are given in a list, and assigned as object attributes. Also splitted CreateUI into CloseSplashScreen and CreatueUI.

ClassImporter now accepts string, callable or class, for compatibility with some old extensions.

Launcher: ShowUI call moves from preStart to start. ShowUI() split into CreateUI() and ShowUI(). Start()'s arguments are passed to CreateUI()
This is meant to allow customizations to pass own pre-instanciated controller to UI at startup.

Launcher: allows customizations to specify what globals passed to extensions

Documentation

Another set of meaningless changes to satisfy PEP8 and PyLint.

PEP8 conformity for modbus. Most of it done by autopep8, plus some easy refactoring.

Add some class factory function to ease declaration of simple POU libraries in customizations (i.e. TC6 XML file only, no special C code generation)

Small pep8 conformity enforcement.

Better have globals passed to python extensions (-e) than locals.

launcher : move call to ShowSplashScreen and BackgroundInitialization to PreStart()
It doesn't change behaviour of launcher in beremiz, but may have some impact on some customizations.
Some customizations need to squeeze some bitmap folder init in between app creation and ShowSplashScreen

modbus extension code cleanup, from smarteh's patch

Merged Mario's modbus branch. Fixed line endings.

merge

Ignore bug report files.

Add support for Modbus (TCP and RTU) working as master & slave

merge

fixed erro introduced 2 commits ago (-e) : tuples have no reverse() method

Trying to get better logging/display of exceptions at runtime's startup

Changed way to deal with extensions arguments (-e) so that path and filename are stored independently and accessible for extensions themselves.

Textviewer : moved call to Colourise in a better place, so that ST highlighting gets also updated when typing in some case, not only IL

Main runtime template C code : Added HAVE_RETAIN preprocessor definition for customized build to signal it provides IEC-61131 Retain memory handling function. Removed targets/Xenomai/plc_Xenomai_noretain.c, now useless.

Clarify licensing, and packaging of runtime only files :
- moved and split targets/typemapping.py into runtime/typemapping.py and runtime/loglevels.py
- added runtime_files.list pointing to files necessary for runtime, and referring to runtime license

Enforced check_source.sh pep8 and pylint rules.

runtime/WAMP: Fixed secret loading into configuration. Fixed secret commandline switch handling.

runtime/WAMP : was 'Added time print on session left.' from dporopat. Purpose is to log (dis/re)connection, to help debugging connection problem

runtime/Wamp : adapt to unicode being enforced in latest crossbar API. Updated some documentation, to explain why there is unused definitions like SubscribedEvents or DoOnJoin.

Extend python<->PLC global variable description "GlobalDesc" to support Initial value setting.

Rebased from dporopat change "add initial value to runtime.py file", which means :
- GlobalDesc is used by some customized beremiz python runtime
- Those runtimes need to know what is initial value of these special variables

update tests/wamp README file, based on changes from dporopat.

Fixed WAMP test (crossbar confile upgrade and use same ID on both PLC and IDE side)

Fixed changes from dporopat and agregorcic about WAMP CRA and config.

WAMP runtime : changes from dporopat and agregorcic, adding CRA (-s) and changed way to load WAMP conf (-c)
- added Challenge Response Authentication,
- use -s commandline switch to give the shared secret.
- WAMP configuration now either given as -c commandline switch
or taken as default wampconf.json in project files.

Set WAMP registration option so that reconnecting while earlier session still didn't timeout is possible (in case of connection lost, for example).

More canonical overload of ReconnectingClientFactory (according twisted doc)

non significant print syntax change. ready for py3.

whitespace cosmetic for pep8

Added arbitrary timeout on Pyro, to force it to free memory after disconnect.

Moved code from to Beremiz_service.py Server class Start method to Loop method to allow customisation by hot patching. Also renamed Stop method as _stop and use Restart instead of Stop from everywhere else to make it clear that _stop actually does restart...

run python tests with non-english locale to catch bugs related to localization

make it possible to update XSD schema in project controller after new
target PLC is added or removed.

For example:


...
import targets
targets.targets["PLC"] = {"xsd": os.path.join(self.customBeremizPath, "PLCtarget", xsd),
"class": lambda: PLC_target,
"code": {"plc_PLC_main.c": os.path.join(self.customBeremizPath, "PLCtarget", "plc_PLC_main.c")}
}

fix commit "lazy initialization of highlight pens and brushes
for DebugVariableViewer" (5562f34f)

clean build example project after running test

fix problem if DataTypeEditor was imported before localization is
loaded

That doesn't affect systems with english locales.

add shell script to run all python tests and automatically handle Xvfb

add PLCOpenEditor tests

run application tests in full screen mode

clean sys.argv, because if test is running from pytest
sys.argv contains string "pytest --timeout 0 ./tests/tools"
Beremiz application parses it and throws exception.

rework Beremiz application "testCheckProject" test to allow easier reuse later

add application name for PLCOpenEditor

This is needed to work user configuration load/store, if PLCOpenEditor
is launched from test environment.

rewrite PLCOpenEditor. Add PLCOpenEditorApp class for easier customizations.

lazy locale initialization

wx.Locale() can't be called without wx.App. So don't call it at
import. It makes PLCOpenEditor simpler.

use CustomIntCtrl instead of wx.SpinCtrl because it doesn't support
long integer needed for UDINT, (U)LINT types.

This commit complements commit 74a3f4d "fix LINT and ULINT ranges".

add custom TextCtrl allowed to enter long integer with bounds checking

It's needed because wx.SpinCtrl supports only 'int' type. For UDINT
and (U)LINT long type is necessary.

use pytest for testing

run separate test on every project instead of one big long test all projects

move configuration for test environment into separate file conftest.py

lazy initialization of highlight pens and brushes for DebugVariableViewer

Constructors wx.Pen() and wx.Brush() require wx.App to exist already.
That causes crash during import of the control,
because import is done before calling main application code.

add '_' function to builtin dictionary at import time

This allows to import many Beremiz python modules before calling
util.misc.InstallLocalRessources().

remove builtin BMZ_DBG. It's not used.

update translation strings

updated all existing translations
added new languages: Portuguese (Portugal), Italian, Hungarian,
Spanish and Bengali. See version.py for information about translators.

fix LINT and ULINT ranges

found installed Inkscape on Windows

tested with Inkscape version 0.9 on Windows 7.

make possible to turn off at compile time online debugging, logging
and external sync functionality

Defines TARGET_DEBUG_DISABLE, TARGET_LOGGING_DISABLE, TARGET_EXT_SYNC_DISABLE
allow to use generated PLC code in low-cost microcontrollers,
integrate into external programs and so on.

main.c:
extern void __run(void);
int main(void)
{
for(;;) {
__run();
// sleep common_ticktime__ ns
// add common_ticktime__ ns to __CURRENT_TIME
}
return 0;
}

Compile for example for arm bare-metal:
../build$ arm-none-eabi-gcc \
-DTARGET_DEBUG_DISABLE -DTARGET_LOGGER_DISABLE
-DTARGET_EXT_SYNC_DISABLE \
-flto -ffunction-sections -fdata-sections -I../../../../matiec/lib/C \
*.c \
-nodefaultlibs --specs=nano.specs -Wl,--static -Wl,--gc-section -Wl,--start-group -lc -lm -lnosys -lgcc -Wl,--end-group

fix clearing project name on opening project properties page.

The problem exists only on Windows with wxPython-3.0.

This happens because callback for EVT_KILL_FOCUS for a first text

This fixes the problem that first message from newer PLC program maybe
lost, if it's issued before first PLC log fetching.

Closes #23

add function block to variable panel if fb is added using toolbar

Closes #25

enable to write SFC transition in IL

This commit reverts previous commit 3f3d97be9a9f.
Because the fix for the matiec problem is already upstream
(https://bitbucket.org/mjsousa/matiec/commits/ce026aee03e00c0790948a18bd7b35805457da81)

fix debug button and variable tree generate for actions and transitions in POU instance variable panel
for 'None' type instances(Python POU's, Native, SVGUI, user-defined pou's, etc.) debug button will be disabled. If action or transition instances have opened in instance variable panel,variables from main POU will be loaded. When user press debug button on variable instance in action or transition, instance path to main POU will be used, because all variables of action or transition in instance variable tree belong to main POU.

clear variable location cell in variable panel, if variable class or type changed
if variable class is not local or global, or variable type is not locatable, variable location cell would be empty and read-only

runtime is licensed under LGPLv2.1

make command line help message for Beremiz more verbose

fix typos and small errors in Russian translation

merge Beremiz launcher support

Closes #13

rename BeremizIDELauncher.py to Beremiz.py

rename Beremiz.py to BeremizIDE.py

wrap Beremiz startup code into separate launcher class

this should make it easier to make customized version of Beremiz IDE.
It's easy to add own splash, change version, add/disable extensions
and many other things.

For example:

[----- MyBeremiz.py ------]
#!/usr/bin/env python
from BeremizIDELauncher import BeremizIDELauncher

class MyBeremizIDELauncher(BeremizIDELauncher):
def __init__(self):
BeremizIDELauncher.__init__(self)
self.splashPath = self.Bpath("", "splash.png")

def ShowSplashScreen(self):
# comment next line to disable splash entirely
BeremizIDELauncher.ShowSplashScreen(self)

# change version
import version
version.app_version = "3.141-rc52"

def LoadExtensions(self):
# add/modifine list of extensions
# in self.extensions
BeremizIDELauncher.LoadExtensions(self)

if __name__ == '__main__':
beremiz = MyBeremizIDELauncher()
beremiz.Start()

dynamically increase size of dialog window for editing comment block

add hotkeys to open recent projects

For simplicity only last 9 projects are saved.

fix twice shown error message box, when wrong non-valid IEC identifier entered

It happens when non-valid name for variable name or name of field in
structure entered. This issue is described in details here:
http://trac.wxwidgets.org/ticket/16333

apply constraints to names for tasks and task instances in resource configuration

The same rules as for IEC identifiers are applied.
- no non-lating characters, ...
- no IEC keywords
- check for duplicate names in resource configuration

closes #19

Fix russian translation

Merged skvorl/beremiz into default

Safe

broken code is temporarily blocked
This code used to highlight with green color text in upper-left corner (path to current instance) in debug mode, if current instance active. Only SFC actions are affected. #16

fix exception handling
now only one exception dialog is displayed, if many same type exceptions handled (like in #16), and bug reports files always save after exception, not only after pressing "OK" button in exception dialog, closes #17

change directory for saving Beremiz bug reports from current working directory to TEMP directory.

Correct element size, if block type or variable name is wider than block width.
Previously, if size corrected, element changed position to the right (or down, if height is corrected). Now upper-left corner is fixed.

remove non-existed and not necessary self.logger from detecting options in iec2c

remove Linux target from first_steps example

Then default target on the system will be used.

fix IL jumps highlighting in Text Viewer

change white background for icons in PouInstanceVariablePanel to transparent

in wxPython 2.8 panel has white background and therefore white
background is appropriate, but in wxPython 3.0 panel has grey
background (on GNU/Linux and on Windows).
Transparent background looks good on both wxPython versions and on all platforms.

change white background for project tree element to transparent

because on GNU/Linux project tree has grey background, therefore
white background looks not good.

fix second error message in case of error appearing too early to have a wx frame

fix a side effect of 95ecb26fdc4e

remove old unused .cvsignore

fix issue with printing scheme (FBD, LD or SFC) with comment element on GNU/Linux

If you draw FBD scheme and place comment on it and then try to print
it, then no wires will be printed and comment box is empty (text is
missing). This happens only for wx.PrinterDC and not on wx.MemoryDC
that is used to draw print preview window in Beremiz IDE.
Looks like a bug in wxPython or wxWidgets.

There were found several workaround for this issue.
1) If some dc.DrawLines call is placed before dc.DrawPolygon, then the
problem is gone.

...
dc.DrawLines(polygon)
dc.DrawPolygon(polygon)
...

2) Reseting DC brush solves the problem as well (see this changeset).

detect iec2c options and ieclib path only once during the first build

attach checkedBlockDict variable to the body object

fix file header in AboutDialog.py

update Russian translation

check before program generation whether SFC step, that is referenced
by SFC jump, does exists

use translatable descriptions for stadard and additional IEC function
blocks from xml files instead of hardcoded in python

move code in mki18n.py generated translation strings from custom files into separate function

clean search result panel after open another project

fix highlight of search result in Search Result Panel
Remove previous highlight, after next search result clicked.

fix doubling search results in Search Result Panel

After fix local search in SFC POU in 163d3a8, search results tree assemble with "children" branches: results of search in actions anf transitions. Deleted code doubling this search results into one more separate branch, so it's useless.

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):

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.

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.

start/stop from taskbar icon only if PLC is stopped/started

close Pyro socket after daemon stop


without that socket port is open after daemon shutdown.
As a result if you restart daemon with new settings (service name, for example),
it can't listen on already used port and opens the next free TCP port
regardless of requested settings.

add python-wxgtk3.0 support to Beremiz_service.py

make about dialog on Windows not so big


It was automatically expanded to place description in one line.

update Russian translation

add i18n to PLC status

Extra strings are added to the code to make mki18n.py to find these
strings in source files and put them into i18n/messages.pot.

remove clear and reset execution order buttons in popup menu in SFC and LD viewers.

fix initial(equal to the min) number of sequences in SFC Divergence dialog.

make only correct blocks(by IEC 61131-3 standard) available in wire popup menu in SFC Viewer

move EnhancedStatusBar.py to the right location

add internatialization support to startup messages during checking software updates

fix translation strings with multiple parameters


this fixes a lot of warnings given by msgmerge:

../PLCOpenEditor.py:196: warning: 'msgid' format string with unnamed arguments cannot be properly localized:
The translator cannot reorder the arguments.
Please consider using a format string with named arguments,

change bug report address for PLCOpenEditor to beremiz-devel@lists.sourceforge.net

make error message to be the same as in Beremiz IDE

fix segmentation fault on clicking red point in compilation console if that compilation error coverts several units in plcopen file

closes #11

add localization to time strings in DebugVariablePanel and to dialog shown after variable drag'n'drop

fix issue that if located variable was dropped in location column, then address was changed in wrong row (row - 1).

It's not neccessary to carry about label size. YToRow() does the work.

increase size for time buttons in LogViewer

The buttons are slightly bigger now. This gives more space for label
translations in other languages.
closes #12

don't rebuild the makefile based project if only companyName, projectName or productName are changed

And this fix current encoding issues, because all these information fields can
contain non-latin characters.

add progress bar to status bar

It can be used to display progress during program upload.
To use it call ShowPLCProgress (like ShowPLCProgress("transfered",
10)) in your PLCObject implementation.

fix warning: 'return' with no value in function startPLC

fix inconsistent whitespace

fix license notices in source files and license files under GPLv2+

Previously a lot of files were referenced to GNU Public License 2.1,
which never existed.
All copyright attributions are kept the same.

fix PLC autostart option for Beremiz_service.py

remove old debug code

fix wrong font family in CustromGrid control

closes #10

now only correct chart can be created in SFC Viewer

if user trying to connect incompatible blocks (by IEC 61131-3 standard), wire highlight will become red

add Russian translations for About dialogs

make about dialog boxes use standard wx about dialogs

Any information in dialog can be easily changed without much effort
and the dialog can be easy translated.

Unfortunately on Windows there is no good standard about dialog,
therefore own implementation is used there.
