§HOI4 Save
HOI4 Save is a library to ergonomically work with Hearts of Iron IV saves (plaintext + binary).
ⓘ
use hoi4save::{Hoi4File, Encoding, EnvTokens, models::Hoi4Save};
let data = std::fs::read("assets/saves/1.10-normal-text.hoi4")?;
let file = Hoi4File::from_slice(&data)?;
let parsed_file = file.parse()?;
let save: Hoi4Save = parsed_file.deserializer().build(&EnvTokens)?;
assert_eq!(file.encoding(), Encoding::Plaintext);
assert_eq!(save.player, String::from("FRA"));
The HOI4 binary format can be converted to plaintext
ⓘ
use hoi4save::{Hoi4File, EnvTokens};
let data = std::fs::read("assets/saves/1.10-ironman.hoi4")?;
let file = Hoi4File::from_slice(&data)?;
let parsed_file = file.parse()?;
let binary = parsed_file.as_binary().unwrap();
let out = binary
.melter()
.on_failed_resolve(hoi4save::FailedResolveStrategy::Stringify)
.melt(&EnvTokens)?;
§Binary Saves
By default, binary saves will not be decoded properly.
To enable support, one must supply an environment variable
(HOI4_IRONMAN_TOKENS
) that points to a newline delimited
text file of token descriptions. For instance:
ⓘ
0xffff my_test_token
0xeeee my_test_token2
In order to comply with legal restrictions, I cannot share the list of tokens. I am also restricted from divulging how the list of tokens can be derived.
