Refactoring

[obiwan87]

Add refactoring handlers for:

• Introduce variable
• Extract method
• Safe delete
• Remove unused imports
• Rename
• Inline renaming for identifiers with known scope
• Extract parameter (Ctrl+Alt+P)
• Specify type explicitly
• Move packages
• Move symbols
• Create missing branches in switch and enum arrays

How about Specify type explicitly? I don't need it often, but when I need it, it's really useful in other languages as well.

For instance, here in TypeScript when I am not fully sure of the type, and the type could be obfuscated from generics.

Like for this trivial example:

points_arr := make([]f32, 3 * n)

Added it to the list ;-)

@Dima-369 Added support for "Specify type explicitly". I already found a little bug. The intention is not triggered at the end of an identifier, only at the beginning and in the middle of it

identifier := value        

so if the cursor is after the "r" it won't trigger

Added support for "Specify type explicitly"

Cool, I tested with fmt.println() and with a local proc in the same file, and it worked flawlessly! This is really useful, thanks!

But, it fails on os.args, probably because it is defined like this.

// "Argv" arguments converted to Odin strings
args := _alloc_command_line_arguments()

---

It also fails on this: lines := strings.split("foo", "\n")

Yes, procedures with multiple values are not supported yet. Basically I wasn't sure how Odin handles multiple return values, when stored in only one variable. Would it be always safe to just infer the type of the first return argument?

os.args: Yes, the builtin-stuff is not fully supported yet. I'll look into it in another ticket

I think so, yes.

Got ya.

There is so much more to this functionality. I thought about this feature this morning and there is a lot more to it that I haven't yet implemented. With composite types like procedures types maps and instantiated poly structs it should not work either.

Basically you have to analyze all the types a type might contain and import the package they're in, or use the import that is already defined in the current file.
