structopt-toml

An default value loader from TOML for structopt. It combinates with structopt.

Usage

Cargo.toml [dependencies] structopt-toml = "0.1.0"

Example

If derive(Deserialize), derive(StructOptToml) and serde(default) are added to the struct with derive(StructOpt), some functions like from_args_with_toml can be used.

```rust

[macro_use]

extern crate serde_derive;

[macro_use]

extern crate structopt;

[macro_use]

extern crate structopt_toml; extern crate toml;

use structopt::StructOpt; use structopt_toml::StructOptToml;

[derive(Debug, Deserialize, StructOpt, StructOptToml)]

[serde(default)]

struct Opt { #[structopt(defaultvalue = "0", short = "a")] a: i32, #[structopt(defaultvalue = "0", short = "b")] b: i32, }

fn main() { let tomlstr = r#" a = 10 "#; let opt = Opt::fromargswithtoml(toml_str); println!("a:{}", opt.a); println!("b:{}", opt.b); } ```

The execution result is below.

```console $ ./example a:10 // value from TOML string b:0 // value from default_value of structopt

$ ./example -a 20 a:20 // value from command line argument b:0 ```
