ClassModifier | Modify your Java class files easy with an interactive GUI

Looks like PATH problem.

Use which openapi-generator in terminal or Git Bash, whichever works for you, to find openapi-generator path first.

Antlr4 parser ends prematurely

This could happen when the rule you invoke, parse in your case, is not "anchored" by the built-in EOF token:

Like the text says:

Not all modifiers are allowed on all classes

But, e.g., inner classes can be private/protected.

You can use with to add your own PatternCondition to your element patterns.

Assuming you have an isTopLevel function defined something like this:

When you get an error like "Unexpected input 'foo', expected BAR" and you think "But 'foo' is a BAR", the first thing you should do is to print the token stream for your input (you can do this by running grun Symbols tokens -tokens inputfile). If you do this, you'll see that the a in your input is recognized as a HexDigit, not as an ID.

Why does this happen? Because both HexDigit and ID match the input a and ANTLR (like most lexer generators) resolves ambiguities according to the maximal munch rule: When multiple rules can match the current input, it chooses the one that produces the longest match (which is why variables with more than one letter work) and then resolves ties by picking the one that is defined first, which is HexDigit in this case.

Note that the lexer does not care which lexer rules are used by the parser and when. The lexer decides which tokens to produce solely based on the contents of the lexer grammar, so the lexer does not know or care that the parser wants an ID right now. It looks at all rules that match and then picks one according to the maximal munch rule and that's it.

In your case you never actually use HexDigit in your parser grammar, so there is no reason why you'd ever want a HexDigit token to be created. Therefore HexDigit should not be a lexer rule - it should be a fragment:

After a touch of research, it looks as though your use of the click event is triggering an asynchronous event loop essentially saying "Hey set this thing to be clicked and then fire all the handlers"

Your current code can't see that and has no real way of waiting for it. I do believe you should be able to build and dispatch a mouse click event using the info here. https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/dispatchEvent

I think that should allow you to build a click event and dispatch it onto your element. The difference is that dispatchEvent is synchronous - it should block your test until the click handlers have completed. That should allow you to do your assertion without failures or race conditions.

1. Create an array containing your numbers in string format
2. Create another array that will hold your Step1, Step2, ... variables
3. Map those items into Components based on the current string and its index in the previously described array

You'll have something that looks like this

This syntax will be treated as a pure string: "module module--{this.props.classModifier}". If you want to append string using JSX, try this syntax instead className={"module module--" + this.props.classModifier}.

Is this a problem or how WPF works?

The latter. Please refer to the following answer by Microsoft at Connect:

The framework (or anyone else) is entitled to call the property-getter as often as it likes, for any reason. There's no guarantee it will be called only once.

So this behaviour is expected.
