ordering is useful to avoid an explosion of options.

SPEAK UP.

We could, indeed, have an ordering option parser. But I suspect ordered options are less easy to grok than a string that is explicitly a query the ordering of whose elements are significant.

I've just added slow and fast options - so you can run the tests slowest to fastest or fastest to slowest. That's useful in conjunction with -j because it ensures parallel runs kick off with the slowest test avoiding the situation where you slow test happens to run last and you lose some of the benefit of parallel testing.

So would you really have me add two more switches to prove's top level interface?

The state engine has a fairly general mechanism for building queries from lists of terms - it seems wrong to couple that tightly to prove's UI by exposing each element of its syntax as a top level switch.

Sorry for the yelling, this one just happens to tickle my yelly-bone.


Well quite. But I see it as pretty much orthogonal to the question at hand. If we decided to go with top level switches to control the state engine we'd cross the option ordering bridge. But I simply don't think it's a good idea. As I write there are nine different options that can be passed to --state. Already that would be a lot of pollution in prove's already fairly crowded UI. How is it not better to keep all of those options in the --state namespace? It makes the documentation clearer, the UI easier to remember, the code easier to maintain.

Have you tried it?
