Change scope of classes in Expressive.Helpers from internal to public

[graniero]

Is your feature request related to a problem? Please describe.
I'm working on some custom functions including a variant of the In() function that is less restrictive on the structure of the collection (can be spread over more than one parameter, mixes of single objects and IEnumerables, etc). When I tried to use the same Comparison.CompareUsingMostPreciseType() method as the built-in In() function, I get the compiler error 'Comparison' is inaccessfible due to its protection level.

Basically, just the same easy issue as #85 / #89.

Describe the solution you'd like
For Expressive.Helpers.Comparison, Expressive.Helpers.Numbers, and Expressive.Helpers.TypeHelper, change class scope from internal to public.

I am starting to think I should just open up everything 😄

Happy to include this in the Next Release

@bijington once I have my functions finished up, I'll share info about them with you. If there are any you might be interested in adding to the Expressive repertoire in a future release, I'll be happy to set up a pull request for you to review.

For example, another one I've built is a JoinText() function that lets you concatenate a collection of strings and evaluable expressions (same permissive parameter structures as described above for In()) , with a delimiter character/string between each one (can be empty for straight-up concatenation). Really handy for composing text from a parameterized template.

@graniero great thanks. I can see the value in that one much like string.Join. Something that has cropped up where I currently work is the possibility of a Format function that would work in a similar way to string.Format, is that potentially of value as a shared function?

[graniero]

Yep, it's basically the same as string.Join.

A Format function would be really cool in general, but on my current work project it's not a priority need. It's an engineering monitor & control system, so the vast majority of my Expressive usage is for math calculations and logical tests. My life is buried in communication protocols and calculation & rule engine construction. 😬

I am using Expressive in a few places though to set up a crude 'text template' with some simple value substitution, and no real need for formatting the subbed values. I originally built the JoinText() function to make nice comma-separated lists of text elements, then realized it basically covers all my text template needs too. Having multiple IEnumerable parameters lets me mash together sub-templates too.

[bijington]

Sounds great! Thanks for sharing some details about how you use Expressive too 😄

[bijington]

Sorry I do intend on getting this done soon

[graniero]

No worries. I've been totally absorbed building functionality to deadline in another part of the system. I won't be back into that part for about a week - you know I'll be back at it when I finally set up that PR with the functions I promised for you. 😬
