So I use Is and Has differently on my property and field names, depending on what they do.

Is implies the state of something, whereas Has implies containing something.

I've even had to use both for the same item. On my FSM code I have IsAccepting and HasAccepting, the first indicates whether the state is accepting, the second indicates whether itself or any states it contains is accepting- basically if it has any accepting states. Heavily commented in that case, and is fortunately the only place I've ever had that happen.

But it leads me to weird things like "IsEnded" instead of "HasEnded"

When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

If a State object can be accepting when its IsAccepting property is true, I recommend renaming HasAccepting to HasAcceptingStates.

I considered that too. It conflicted with another method that operates on a collection of otherwise potentially unrelated states, but then I ended up renaming it later to HasAnyAcceptingStates()

The api is kind of confusing because of the self-repeating, fractally nature of state machines like this. There are all kinds of subtly different but highly related operations on them. Even shoring up the API and naming took me going back to it over the years, never 100% satisfied, but it's more or less frozen at this point.

And, given what I've seen of the other similar APIs out there (usually in Java), mine is far cleaner. They're all nasty. Mine at least reins in the crazy somewhat, but then I'm sure everyone thinks that about their own code Roll eyes | :rolleyes:

I'd prefer IsNull or IsEmpty (depending on what it was)

but actually for those things I typically sidestep it altogether with

bool TryGetValue(...,out T value)

Use YodaNaming: "EndedItIs" and "EndedItHas" - that way masked nicely any confusion is.

they would match my yoda conditionals like

States

    GetStates(State state)  => IEnumerable<State>
    
    GetAcceptingStates(State state) => IEnumerable<State>
    
    GetNonAcceptingStates(State state) => IEnumerable<State>
    
    GetStateStatus(State state) => enum // ended active closed ... ?
    
    SetStateStatus(State state) => bool ? or error code ?
    
    HasAcceptingStates(State state) => bool
    
    IsStateAccepting(State state) => bool

Is this simply confusion with IS_A and HAS_A ?

No criticism intended, but I use:

public bool Ended
{
    get
    {
        bool value = false;
        //...
        return value;
    }
}

I've never liked the IsCondition or HasThing naming style, probably because they have a whiff of Hungarian notation about them.

when I'm in .NET land I adhere closely to the .NET naming conventions.

Over the years I've become far less about personal preference, and far more about when in Rome.

At best i tend to build on them rather than change them.

I have to do that a lot more now than I used to. My group has been down-sized from 17 to 5 people over the last 5 years, and so I get to maintain a fair amount of other folks' code. Sometimes it takes a shot of whiskey with a Zofran[^] chaser to stay consistent with how they did things, but as long as it pays the bills...

I've had some good luck with Buddhism in terms of overcoming this.

Not trying to convert anyone - I'm not a buddhist myself, but my first serious boyfriend was and he drilled a lot of it into me when i was still impressionable.

The headshrinkers call it Dialectical Behavioral Therapy, but all it really means is just relax. $Shucks | :-\$

The world will keep turning no matter how people name things.

If I can understand it, then all is good. If I can't, then there is opportunity for growth in the challenge.

Or, more likely I'll just smash something. Laugh | :laugh:
