Feature Request - Test Lexer Rules

[nmz787]

Lexer rules can't be tested, but having them work correctly is fundamental to having a parser rule work.

I was able to code Python unit tests for the lexer rules, to aid in my development and debug:

but it was quite unexpected that the visual plugin couldn't do this.

I think #417 is the same request as yours? If there was a new tab in the right part of the preview, showing the list of tokens that were lexed, would that be enough?

@nmz787 is it something like this you're looking for? #417 (comment)

Closing as duplicate of #417

[nmz787]

I don't think #417 is the same thing. #417 wants to see tokens associated with a specific parser rule. This ticket (430) is about wanting lexer tokens, without having written a parser.
