Simple every day type conversion tooling.

Thanks to modern golang and generics, you can say now:

pointerToOne = tc.P(1)

instead of using tons of typed casters like this.

There are different variants for this function: nil pointer for zero values, defaults... take a look at documentation

There are functions to cat any to any type with or without fallback to default. Like this:

x := tc.DefCast(ctx.Value("key"), "default") // x = "default" if there is no "key" in context

or without default

x := tc.SafeCast[int](ctx.Value("key")) // x = 0 if there is no "key" in context

Package provides sort of ternary operator:

// useful for globals
var messagePrefix = tc.Cmp(os.GetEnv("APP_ENVIRONMENT") == "prod", "", "[FROM STAGING] ")

and extended operator that deals with *bool, considering &true, &false and nil:

user := struct {
    Male *bool
}{}
gender := tc.CmpN(user.Male, "male", "female", "n/a")

You can simply assume defaults for zero values like this:

var tmpDir = tc.DefZero(os.GetEnv("TMP"), "/tmp")
