CLI: Add negation flags like clang or gcc

[furesoft]

Passing a false value use a negation like --no-execution instead of --execution false

[FrankRay78]

Hello @furesoft , can you please provide links to the appropriate clang/gcc manual entries/help illustrating this behaviour?

[furesoft]

hmm. I cannot find a description but the man page show some example flags

[FrankRay78]

@furesoft Do you imagine that when a command setting has a flag defined as a boolean, then automatic parsing and acceptance of the --no- prefix is also supported OOTB? Have you done this on any of your own apps, out of interest?

[furesoft]

What's OOTB?

I did not implemented yet because I had no usecase for it and didn't know the option exists. I am working on a compiler and the current option to negate flags would be combersome.

[FrankRay78]

OOTB is 'out of the box'

I'm trying to understand why you wouldn't just add the required negative flags to the settings, and use these accordingly in the command.

Is there a reason why this isn't the best way forward? I ask from a place of ignorance not having seen this request before.

[furesoft]

It is possible but I plan to allow kind of 15 flags that can be used to enable specific optimization passes. adding the negative option would result in 30 flags to implement. It's not mandatory but would be nice to have some kind of negation

Understood. Thanks for raising, it's an interesting use case.
