#!/usr/bin/env python
"""
The flag types that ship with the cli library have many things in common, and
so we can take advantage of the `go generate` command to create much of the
source code from a list of definitions. These definitions attempt to cover
the parts that vary between flag types, and should evolve as needed.
An example of the minimum definition needed is:
{
"name": "SomeType",
"type": "sometype",
"context_default": "nil"
}
In this example, the code generated for the `cli` package will include a type
named `SomeTypeFlag` that is expected to wrap a value of type `sometype`.
Fetching values by name via `*cli.Context` will default to a value of `nil`.
A more complete, albeit somewhat redundant, example showing all available
definition keys is:
{
"name": "VeryMuchType",
"type": "*VeryMuchType",
"value": true,
"dest": false,
"doctail": " which really only wraps a []float64, oh well!",
"context_type": "[]float64",
"context_default": "nil",
"parser": "parseVeryMuchType(f.Value.String())",
"parser_cast": "[]float64(parsed)"
}
The meaning of each field is as follows:
name (string) - The type "name", which will be suffixed with
`Flag` when generating the type definition
for `cli` and the wrapper type for `altsrc`
type (string) - The type that the generated `Flag` type for `cli`
is expected to "contain" as its `.Value` member
value (bool) - Should the generated `cli` type have a `Value`
member?
dest (bool) - Should the generated `cli` type support a
destination pointer?
doctail (string) - Additional docs for the `cli` flag type comment
context_type (string) - The literal type used in the `*cli.Context`
reader func signature
context_default (string) - The literal value used as the default by the
`*cli.Context` reader funcs when no value is
present
parser (string) - Literal code used to parse the flag `f`,
expected to have a return signature of
(value, error)
parser_cast (string) - Literal code used to cast the `parsed` value
returned from the `parser` code
