fix unnecessary lambda and enable corresponding pylint check

fix wrong-import-order. first standard modules are imported, then others

fix (old-style-class) Old-style class defined error for most parts of
the code

only PyJS code is left, because it does some fancy tricks and can't be
easily fixed. So far PyJS doesn't support Python3 anyway.

remove in-tree version of Zeroconf and use upstream from
python-zeroconf package

remove reimported modules

fix unnecessary parens after keyword

enable pylint checker

so far only print statement is checked

fix usage of python2-only print statement

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")}
}

from ProjectController import ProjectController, GetProjectControllerXSD
ProjectController.XSD = GetProjectControllerXSD()

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

make default caption for PouNameDialog translatable

fix max value for UDINT and ULINT types

update Build icon

add couple Beremiz application tests

These tests trigger around 45% of python code.
Used in tests docker files are avaiable here:
https://bitbucket.org/skvorl/beremiz-dockerfiles

fix problem if _should_write is called by expired timer after
termination of wx application.

Initial Bitbucket Pipelines configuration

fix bug with unfinished debug thread
this bug occurs when user doesn't stop debugging process in current project, and opens another project

unify exception handling of Beremiz and PLCOpenEditor

fix problem running PLCOpenEditor

$ ./PLCOpenEditor.py
../src/common/stdpbase.cpp(62): assert "traits" failed in Get(): create wxApp before calling this

Regression was introduced by '3311eea' (clean-up: fix PEP8 E402 module level import not at top of file)

don't check any particular wx version

Beremiz works with any version of wx.

fix problem when Beremiz is running without matiec installed

set matiec settings only once on first use of ProjectController class and give
user-friendly message on compilation about missing matiec
installation.

skip hidden files and directories on permission check

To fix problems with git, because .git subdirectory contains
read-only repository objects.

change structure of filename for bug reports in Beremiz and
PLCOpenEditor so bug reports could be easily sorted by name

fix target Xenomai missing functions

update messages.pot and messages.po

mki18n.py: generate messages.po (contains English strings in msgstr)

This po file is necessary because Transifex translation platform
automatically can only import PO files. Usually messages.pot is
enough.

add to i18n/README forgotten commands to add some XML schemes as source
for strings and update app.fil

fix problem with hidden FindInPou dialog with wxPython 3.0 on Windows

FindInPou.IsShown() returned True, but dialog was hidden.
At same time On GNU/Linux with wxPython 3.0 there wasn't such problem.
So it's Windows specific.

disable empty coils and contacts in LD/SFC editors

Closes #30

remove debug code

make all dialog have non-fixed size

this fixes the problem, that some controls may be hidden in some cases, because
dialog size is too small. This can happen when system fonts are bigger
than expected, default system them controls are bigger or if localized
strings are bigger than in English.

avoid infinite loop in search

for example following regexp '()' creates infinite list of result

This caused svgui example to crash.

disallow setting IEC location addresses for TIME, DATE, DT and TOD variables

Size of these types is not defined and depends on the implementation
(IEC 61131-3 2.3.1).

if there is no users matiec installation, then use system path to run iec2c

search for matiec libraries in system path as well

Closes #29

remove child node from add child node menu, if max count of the same type nodes reached

fix reducing groups with ordered elements

fix extra brace

add getCompiler and getLinker methods, to abstract from XSD.
add calc_source_md5 as it's more convenient especially for embedded
targets to add -DPLC_MD5="something" option at compile time than
to mess with editing binary.
add some more helper methods

make run Beremiz and PLCOpen Editor, if full path contain non-lating
characters

There was a problem in About dialog and in project properites tab and
probably in my other places, when str is automatically converted to
unicode string using ascii.
This patch converts str to unicode using proper encoding at the very beggining.

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
control (project name) is called just after creating page with project
properties. It happens before initializing text controls from PLCController.

fix problem with debugging external string variables

Debug update stopped if external string variable added to debug
variable panel.

fix problem with clearing non-empty location field after changing type of config variable

introduced by cd9db17 ("clear variable location cell in variable
panel, if variable class or type changed").

Closes #26

fix backtrace on opening program/resource on small screens

Fix regression introduced by f4696d8 ("add stretching to columns Name,
Type, Doc in variable panel").
This problem happens only on wxPython-3.0.

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

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()

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.
