`mumu-string` is a powerful string utilities plugin for the Lava language. It provides a rich set of string manipulation functions—ranging from basic case conversion to concatenation, slicing, replacement, partial application, and more.

---

## 🚀 Features

- **Unary helpers**: `lower`, `upper`, `trim`, `length`, `to_string`.
- **Multi-argument utilities**: `concat`, `split`, `join`, `replace`, `contains`, `starts_with`, `ends_with`, `slice`, `repeat`, `index_of`, `last_index_of`.
- **Placeholder & partial application support**: Supports `_` for currying functions.

Example usage in the REPL:
```lava
string:concat("Hello", "World")          ; "HelloWorld"
string:replace("foo bar foo", "foo", "baz") ; "baz bar baz"
string:trim("  spaces  ")               ; "spaces"
string:slice("abcdef", 2, 5)            ; "cde"
```

## 🛠️ Installation

Add `mumustring` to your `Cargo.toml`:

```toml
[dependencies]
mumustring = "0.1.0"
```

### As a Lava plugin

Compile and install the shared library:

```bash
git clone https://gitlab.com/your-org/mum-ustring.git
cd mumustring
make
make install
```

This places `libmumustring.so` (and symlink `libstring.so`) into `/usr/local/lib/`. Then in the Lava REPL:
```lava
extend("string")
string:upper("hello")  ; "HELLO"
```
