> Turn runes into commands.

runex is a cross-shell abbreviation engine that expands short tokens into full commands in real-time.

## Features


- Cross-shell support (bash / pwsh / cmd / nu)
- Real-time expansion (space-triggered)
- Single config file
- Conditional rules (OS / shell / command existence)
- Fast and lightweight (Rust core)

## Concept


runex treats short inputs as **runes**, and expands them into full **casts**.

```
gcm␣ → git commit -m
ls␣  → lsd
```

## Installation


```bash
cargo install runex
```

## Setup

### PowerShell

Temporary:

```powershell
Invoke-Expression (& runex export pwsh)
```

Persistent (`$PROFILE`):

```powershell
if (!(Test-Path $PROFILE)) { New-Item -Type File -Path $PROFILE -Force }
Add-Content $PROFILE 'Invoke-Expression (& runex export pwsh)'
```

### bash

Temporary:

```bash
eval "$(runex export bash)"
```

Persistent (`~/.bashrc`):

```bash
echo 'eval "$(runex export bash)"' >> ~/.bashrc
```

### Nushell

Temporary:

```nu
runex export nu | save ~/.config/nu/runex.nu
```

Persistent (`config.nu`):

```nu
mkdir ~/.config/nu
runex export nu | save -f ~/.config/nu/runex.nu
open ~/.config/nu/config.nu
```

Then add this line to `config.nu`:

```nu
source ~/.config/nu/runex.nu
```

### cmd (Clink)

Temporary / install script:

```cmd
runex export clink > %LOCALAPPDATA%\clink\runex.lua
```

Persistent:
If Clink is installed and loads `%LOCALAPPDATA%\clink\*.lua`, the file above is enough.

## Config

`~/.config/runex/config.toml`

```toml
version = 1

[[abbr]]
key = "ls"
expand = "lsd"

[[abbr]]
key = "gcm"
expand = "git commit -m"
```

## Commands


```bash
runex expand --token ls   # expand a single token
runex list                # list all runes
runex doctor              # check config and environment
runex export <shell>      # generate shell integration script
```

## Example


```
Input:  gcm␣
Output: git commit -m ␣
```

## Why not alias?


| Feature           | alias | runex |
| ----------------- | ----- | ----- |
| Cross-shell       | No    | Yes   |
| Real-time expand  | No    | Yes   |
| Conditional rules | No    | Yes   |

## Philosophy


- One config, all shells
- Minimal typing, maximal power
- Runes over repetition

## Future


- Fuzzy suggestions
- Interactive picker
- Editor integrations

## Name


- **run** (execute)
- **ex** (expand / execute)
- **rune** (compressed command)
