I built a console app to find all the *.ts files in my project and then compile them using tsc.exe.
Everything was working fine, but as I converted my JavaScript files to TypeScript, I eventually ran into the following error:
ytsc.js(21053, 17) Microsoft JScipt runtime error: 'window' is undefined
Each time this happened when I was trying to extend window:
window['prop'] = "something";
I tested the code until I found the answer, which had little to do with my code...
The fault was my build tool.
I had declared the -e (execute) command line option when calling tsc.exe:
I did this because I thought I might add some automated testing code in the modules.
The cause for the error:
Most of my code is in functions.
However, there were a few places that I wanted to extend 'window' (for example if a built in function is missing from an old browser, I was shimming those calls). The code to shim the window object was running as the file loaded:
if (window.fun == null) {
window.fun = function(){...};
}
Anyway, because of the -e option, the tsc.exe was attempting to run the code (outside of a browser environment). This caused the above error.

I am trying to use documentation using docstrings- my code is written in cython and compiles fine normally
When I try to run
pdoc --http localhost:8080 main.pyx
I get a bunch of errors such as
module 'mongo' has no attribute 'retrieve_all_fundamental_events_from_db
while in fact my mongo.pyx module does have the function 'retrieve_all_fundamental_events_from_db' and it works perfectly fine otherwise
How to fix this? Does pdoc work with cython?
UPDATE:
The JS version of closure-compiler is no longer supported or maintained.

Im trying to find if there is a way to remove the "debugger" keyword during compilation process, im using the javascript version google-closure-compiler with gulp.
Looking through the documentation it is clear we can set the flag to stop/show error messages during compilation by doing the following.
https://github.com/google/closure-compiler/wiki/Flags-and-Options
--jscomp_off
translating this to gulp, it is:
const googleClosureOptions = {
...
jscomp_error:"checkDebuggerStatement"
}
however this works on stopping the compilation by throwing error or to show a warning.
zyxcdafg.js:1444: ERROR - [JSC_DEBUGGER_STATEMENT_PRESENT] Using the debugger statement can halt your application if the user has a JavaScript debugger running.
debugger;
^^^^^^^^^
but what I am trying to achieve is to remove the debugger keyword. Is this possible to achieve using googleclosure. I can not find any flags or options relating to this.

No I don't think so. I'd suggest you use something else to do it. Like sed:
find dist -name "*.js" -exec sed -i 's/\sdebugger;//' {} +
Something like that will find files in your dist folder that end with .js and then exec-ute sed to replace all instances of debugger; with nothing.
You could add that to a script that calls your Closure Compiler build.
The compiler doesn't have a command-line api for defining custom code removal passes, but the compiler's architecture does allow for registering custom passes and a pass to remove a debugger statement should be trivial:
if (n.isDebugger()) {
compiler.reportChangeToEnclosingScope(n);
n.detach();
}
The general structure would follow:

I'm trying to use Graphics32 package. Graphics32 was compiled and installed without any issue.
When I try to execute (debug) following code under C++ Builder XE3
TBitmap32* bmp = new TBitmap32();
bmp->LoadFromFile("d:\\sample.bmp");//This calls SaveToStream instead of LoadFromFile
...
it calls another member function SaveToStream which I can trace into and step while debugging until AV rises.
I have never encountered such behavior before.
Is there any compiler directive I'm missing or some workaround to make proper function call?
Update: I use the Graphics32 source from SVN. Everything works good if I use code prior to revision 2122.
I'm currently develop an Objective-C library that links to the MariaDB C connector. I believe there is a problem with the library, though.
Every time I execute my code I get very strange errors on the console. The -(id)init method of my library calls mysql_init(NULL) to initialise the library but as soon as I return from -(id)init I get the following errors in the console:
Object 0x10643df70 of class XXX autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug
Thing is, there is no multithreaded code being executed and if I run the same - (id)init without the call to mysql_init(NULL) the errors disappear. I believe the libmariadb library is causing these errors to appear. I don't get why though.
Do I need to build it with any special command line switches? Am I calling the right methods? I obviously used the MySQL online documentation as a guide.
Make sure you add this anytime you have a new thread:
#autoreleasepool {
//enter code here
}
Have you tried latest revision from launchpad?
Also try to build libmariadb with -DUNDEF_THREADS_HACK and
CMAKE_USE_PTHREADS:BOOL=OFF)
I was busy with other stuff for a while. I've since updated MariaDB to the latest version and, as far as I can tell, it works fine.
I want to let my app to run sound while the playbook in standby mode, I put this statement in the start up
QNXSystem.system.inactivePowerMode = QNXSystemPowerMode.THROTTLED;
Now when I debug the app on the simulator (not desktop debugger) I got this error
VerifyError: Error #1079: Native methods are not allowed in loaded code.
And this error I got also when using AlertDialog.
Note: I am using Flash builder, and I have put the qnx SWC in the libraries path.
.... so to solve these problems?
To allow code compiled w/native extensions to run on the simulator, we had to put code that used native extensions in methods that would never get executed (when on the simulator).
It wasn't enough to just wrap the offending code in an if/else block. The if/else needs to call another method that either has the native version or the simulator version of the code.
For example:
private function showNativeOrFlexAlert(message:String):void
{
// we used the Capabilities class to determine this, might be a better way
if (isMobile)
showNativeAlert(message);
else
showFlexAlert(message);
}
// have to be careful here, this method signature CANNOT include
// any classes from native extension -- no errors on device, but fails on simulator
private function showNativeAlert(message:String):void
{
// use native API to show alert
}
private function showFlexAlert(message:String):void
{
// use the Flex Alert class
}
Set the qnx-air.swc linkage to "external".
