Module config

Expand description

Mdbook’s configuration system.

The main entrypoint of the config module is the Config struct. This acts essentially as a bag of configuration information, with a couple pre-determined tables (BookConfig and BuildConfig) as well as support for arbitrary data which is exposed to plugins and alternative backends.

§Examples

use std::path::PathBuf;
use std::str::FromStr;
use mdbook::Config;
use toml::Value;

let src = r#"
[book]
title = "My Book"
authors = ["Michael-F-Bryan"]

[build]
src = "out"

[other-table.foo]
bar = 123
"#;

// load the `Config` from a toml string
let mut cfg = Config::from_str(src)?;

// retrieve a nested value
let bar = cfg.get("other-table.foo.bar").cloned();
assert_eq!(bar, Some(Value::Integer(123)));

// Set the `output.html.theme` directory
assert!(cfg.get("output.html").is_none());
cfg.set("output.html.theme", "./themes");

// then load it again, automatically deserializing to a `PathBuf`.
let got: Option<PathBuf> = cfg.get_deserialized_opt("output.html.theme")?;
assert_eq!(got, Some(PathBuf::from("./themes")));
