prefixe

Prepend validated prefixes to shell commands, with support for confirmed mappings and speculative candidate learning.

Designed as the core library for coursers / rx prefix config integration.

What it does

Reads a TOML prefix config (~/.config/rx/prefixes.toml by default)
Rewrites shell command strings by prepending a known prefix to each segment
Supports compound commands split on &&, ||, ;, |
Tracks speculative "candidate" probes for learning new mappings on success
Exposes PrefixStore and ProbeStore traits for easy testing and substitution

Usage

use prefixe::{FilePrefixStore, PrefixStore, rewrite_command};

let store = FilePrefixStore { path: FilePrefixStore::default_path() };
let config = store.load();
let result = rewrite_command("gh issue list && gh pr list", &config);
println!("{}", result.rewritten);
// → "op plugin run -- gh issue list && op plugin run -- gh pr list"

Config format

~/.config/rx/prefixes.toml:

[mappings]
gh = ["op", "plugin", "run", "--"]
"cargo test" = ["dotenvx", "run", "--"]

[[candidate_prefixes]]
candidate_prefixes = [["op", "run", "--"]]

learn_on_successful_fallback = true
