go-wrap

Overview

The concept of this package is to use Out[T] for each function within the project or to use Wrap[T](val T, err error) (another function in this package to wrap common tuples like return val, err). Alternatively, you can use OK[T](v T) or Err[T](err error) to convert any value into these forms.

The package includes a list of handlers such as And (also AndXN where N is a number up to 9), Join, Proof, Range, Each, ReadChan, Sliced (with Async versions of these functions). Additionally, Just, DisJoin, and Flat are provided to create a more declarative style.

go generate

You can go install this package and later use it with //go:generate go-wrap, along with the following flags:

• exclude: A list of comma-separated function names to exclude.
• mode: Specifies the visibility and type of functions to generate. Available options are:
  • pub (default)
  • priv
  • all
  • priv-rcv
  • pub-rcv
  • all-rcv
  • priv-fun
  • pub-fun
  • all-fun

These flags are used to generate wrappers for regular functions and methods that can return a variety of signatures:

• ()
• (V)
• (error)
• (V, error)

Where V is a value of any type.
