is-callable | Is this JS value callable | Script Programming library

I'm currently using ESLint in my project, and have configured it to run inside VSCode, and enforce a custom ruleset. So far it is working as expected, and flagging lines in my code where violations occur. I now need to specify that the environment is browser (as suggested in the solution to this issue). How exactly do I do that, yet keep everything else about ESLint working as-is?

• That GitHub issue indicates I need to edit my .eslintrc file. But I don't see any such file in the root of my project. I do see .eslint files in several different dependencies, e.g.

C:\Users\snarl\development-snarl\development-wordpress\linting-wordpress\node_modules\is-callable

I could be wrong, but those don't seem related.

• I tried creating a new file--.eslintrc.json--in the root of my project, and adding to that file:

{ "env": { "browser": true } }

But when I did this, and re-checked ESLint inside VSCode, it stopped flagging the rules in my custom ruleset (examples), and actually flagged a new rule (screenshot). This seems to completely supersede some of my existing ESLint settings, rather than supplement them.

Thanks.

I'm a bit confused about calling Calling UWP APIs from a desktop app. The last sentence of the first paragraph of this link states:

I always use to develop my projects natively for Android and iOS, but after many people talking to me about react-native, I decided to give it a try.

However, I got very frustrated at the very first initial step: create my first project.

This is my environment:

• macOS Mojave 10.14
• Xcode 10.0
• node v10.12.0
• watchman 4.9.0
• react-native-cli: 2.0.1

When I run the command react-native init AwesomeProject, I see many warnings like this:

Problem description:

C++17 introduces std::invocable, which is nice to detect if a type... is invocable with the given arguments. However, would there be a way to do it for any arguments for functors (because combinations of the existing traits of the standard library already allow to detect functions, function pointers, function references, member functions...)?

In other words, how to implement the following type trait?

I have returned to c++ after long years of Java/Node.js programming so, I am out of touch with the templates (I am working on that).

While revising concurrency, I accidentally stumbled upon the following case

I don't find any way online or scratching through the PHP docs to do this.

Is there a friendly or light way check if a variable is a Magic Constant like __FILE__ or __DIR__? Similar to is_callable()?

I want to check against the $var passed and run some if/else conditions on it.

Small example.

I'm attempting to use SFINAE to detect if a type passed as a template argument T has an T::operator()(P const&) where P is also a template argument. I modeled my solution after this example of the Member Detector Idiom Unfortunately, I could not get this working for an operator(), even though I could get it to function for a normal method.

Here's some sample code that demonstrates the problem I'm facing:
