"""
|
||||
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
