generator-express | express generator for Yeoman | Runtime Evironment library

Generator expressions are usable only for some properties and some variables, so they could be evaluated at the end of configuration stage to a values, which depends from the build type. Such behavior cannot be achieved with plain if because multi-configuration CMake generators (like Visual Studio) read a CMakeLists.txt once but create several configurations.

Generator expressions are usable also for the commands which sets these properties and variables.

Every possible usage of generator expressions is explicitly stated in the documentation for a command/property/variable which supports them.

Documentation for the command set_target_properties doesn't describe usage of generator expressions, so this command simply doesn't support them.

Actually, one can pass to that command a generator expression as a property's value. In that case the command will just assign that value to the corresponded property. It is dependent from the property whether the generator expression will be resolved when evaluate the property after the configuration.

But neither the name of the target not the name of the property cannot be a generator expression.

For conditionally set properties for a target, use plain if:

Handling multiple configs in the $ generator expression has been introduced only recently with CMake 3.19. Versions before only accepted a single configuration argument to the generator expression.

I figured it out!! cmake was building my application as a console app, instead of a Windows app. Replacing add_executable(${TARGET_NAME} ${MY_SOURCES}) with add_executable(${TARGET_NAME} WIN32 ${MY_SOURCES}) in my cmake build makes the performance match. I learned something new today, thanks all.

Combining the suggestions in the comments you can achieve the exact behavior you're looking for. I will not go into details as to how generators work, as you have much more concise answers from experienced people. I will though sum-up that the point with generators is that they yield for you the next element only when you ask for it. And generators are objects just as anything else in Python, so as long as you are sharing the same generator object you will always have a bookmark of the last element yielded. Now to better understand with code:

First we will generalize the looper function:

Is this the correct approach?

Approach, yes. But don't expand IOS, if handles that. Just:

There is this sample in the official repo: https://github.com/spring-projects/spring-integration-samples/tree/master/basic/sftp

You really should be sure that you place there in the remote /tmp/charge/ the file with a .txt extension.

You probably also need to turn on DEBUG logging level for the org.springframework.integration to be really sure what is going on in your application.

Your example doesn't really specify a use case for this, and I think there are other ways of going about it (as well as -lblas being a linker flag not a compile option.) Just off of the information you provide, it looks like what you might want is:

unless you're prepared to put in a fix to MxNet yourself and submit a pull request, your best solution is to switch versions of python. 3.7 is still very recent and shouldn't give you any trouble with any other libraries you may use. I recommend you install 3.7, but keep 3.8 on your computer and use virtualenv to create custom library install environments for each... for example, I just found this link to take you through the steps... https://www.freecodecamp.org/news/installing-multiple-python-versions-on-windows-using-virtualenv/

I personally use anaconda and environments through that, which actually has similar steps (using anaconda prompt) no matter which OS you are on. But this can all be done without anaconda and with virtualenv as above.

You've made me curious, so you've made me look this up. First, when you look at the resulting byte code, it already uses STORE_NAME with the "mangled" name.

Who does it and when then? https://github.com/python/cpython/blob/master/Python/compile.c Holds the answer:

This file compiles an abstract syntax tree (AST) into Python bytecode.

And the corresponding function would be _Py_Mangle ("Name mangling: __private becomes _classname__private.")
