Improve templates for the Swift standard library

[vinivendra]

The templates file currently covers a few parts of the Swift standard library, mainly Strings and Arrays. This issue will be used to keep track of expanding the standard library support to other types and methods.

Do you have a list of types you'd like to be covered? Otherwise, there could be multiple PRs, each covering one to a few classes at a time.

[vinivendra]

Yeah, multiple PRs would definitely be best.

I don't have a list yet. I thought about maybe using something like the documentation to create a list, at least so we can be sure we considered everything (even though we won't be able to translate everything).

[sgade]

Alright, when I find the time I'll go over it and look at possible classes and methods that need translating.
Might be only in a couple of weeks, though.

[sgade]

So I dug through the documentation link you provided and came up with a list of types and functions that should be looked at in how they are translated. Most are covered already.

I will dump this list here as you are currently working on the SourceKit AST version of gryphon if I am not mistaken.
Once that is done, we could look at how the following types are translated and if any need special templates.

What do you think?

Int
Double
Float

ClosedRange

Looks great!

Yeah, I'm working on SourceKit right now, but this could be done in parallel if you want to.

Based on your list, I created a new Status.md file we can use to track development. I'm not sure I like how it turned out though, so suggestions for improving it are welcome.

If you want to begin implementing the new templates, I'd probably start with the easier "concrete" types (Bools, Ints, basically anything that isn't a protocol) and do something like this:

• Create the template in a test file so you can tinker and make sure it works OK.
• Add your template to the gryphonTemplatesLibraryFileContents string (around here)
• Add some tests in Test cases/standardLibrary.swift (also Test cases/standardLibrary.kt and Test cases/standardLibrary.output).

In any case, let me know if you need help!
