# humfmt
**Ergonomic human-readable formatting toolkit for Rust**
[](https://github.com/MuXolotl/humfmt/actions/workflows/ci.yml)


</div>
---
`humfmt` is a lightweight Rust library for turning raw machine values into human-friendly text.
Designed to provide:
- compact number rendering (`15320 -> 15.3K`)
- fluent builder-style customization
- locale-ready suffix formatting
- ergonomic extension trait API
- `no_std`-friendly usage with `alloc`
- zero-macro, zero-nonsense usage
The crate aims to be tiny, intuitive, and pleasant enough that formatting stops feeling like work.
---
## β¨ Quick Example
```rust
use humfmt::Humanize;
fn main() {
println!("{}", humfmt::number(15320)); // 15.3K
println!("{}", 1_500_000.human_number()); // 1.5M
}
```
---
## βοΈ Customized Formatting
```rust
use humfmt::{Humanize, NumberOptions};
fn main() {
let out = 15_320.human_number_with(
NumberOptions::new()
.precision(2)
.long_units()
);
println!("{out}"); // 15.32 thousand
}
```

## β
Current Features
* [x] Compact number formatter
* [x] Builder-style `NumberOptions`
* [x] `Humanize` extension trait
* [x] Long and short suffix units
* [x] Locale abstraction foundation
* [x] Doctests and integration tests
---
## πΊοΈ Planned Roadmap
Upcoming humanizers planned for future releases:
* [ ] `bytes()` β human-readable byte sizes
* [ ] `duration()` β compact duration formatting
* [ ] `ago()` β relative time rendering
* [ ] `ordinal()` β 1st / 2nd / 3rd style helpers
* [ ] additional locale packs
* [ ] zero-allocation optimization pass
---
## π¦ Installation
Add dependency:
```toml
[dependencies]
humfmt = "0.1"
```
For `no_std` targets with `alloc` available:
```toml
[dependencies]
humfmt = { version = "0.1", default-features = false }
```
---
## Feature Flags
- `std` (default): enables the standard-library build.
- `default-features = false`: builds the current formatter on `no_std` + `alloc`.
- `english` stays in the default set for forward-compatible locale gating in `0.1.x`.
- `alloc`, `russian`, and `polish` are reserved compatibility flags in `0.1.x`; they do not change runtime behavior yet.
- `chrono` and `time` keep their optional dependencies wired and CI-checked, but no public integration API is exposed yet.
---
## π§ͺ Development Status
`humfmt` is under active early-stage development.
The current public surface is intentionally small and focused on compact number formatting first.
Expect rapid iteration, formatter additions, and locale improvements.

## β Philosophy
This crate follows one simple rule:
> Human formatting should feel stupidly easy.
No giant config structs.
No formatting gymnastics.
No "why is this so annoying?" moments.
Just:
```rust
println!("{}", 1500000.human_number());
```
and move on with your life.
