## π¦ Installation
### Install on Arch Linux (via AUR)
If you're on Arch Linux or an Arch-based distribution (like Manjaro), you can install LeenFetch from the AUR using an AUR helper like [`yay`](https://github.com/Jguer/yay):
```bash
yay -S leenfetch
```
or
```bash
git clone https://aur.archlinux.org/leenfetch.git
cd leenfetch
makepkg -si
```
### Install on Debian / Ubuntu (via .deb)
If you're on Debian, Ubuntu, or a Debian-based distribution, you can download and install the `.deb` package from the [GitHub Releases](https://github.com/drunkleen/leenfetch/releases):
- AMD64 (x86_64)
```bash
wget https://github.com/drunkleen/leenfetch/releases/download/v0.2.1/leenfetch-v0.2.1-debian-x86_64.deb

sudo dpkg -i leenfetch-*.deb
```
---
### Install on Fedora / RHEL (via .rpm)
If you're using Fedora, RHEL, or another RPM-based distro, you can install LeenFetch using the `.rpm` file from [GitHub Releases](https://github.com/drunkleen/leenfetch/releases):
- AMD64 (x86_64)
```bash
wget https://github.com/drunkleen/leenfetch/releases/download/v0.2.1/leenfetch-v0.2.1-REHL-x86_64.rpm
sudo rpm -i leenfetch-*.rpm
```
---
### Install on Windows (via .zip)
If you're on Windows, download the latest `.zip` from the [GitHub Releases](https://github.com/drunkleen/leenfetch/releases):
powershell:
- AMD64 (x86_64)
```powershell
Invoke-WebRequest -Uri "https://github.com/drunkleen/leenfetch/releases/download/v0.2.1/leenfetch-v0.2.1-windows-x86_64.zip" -OutFile "leenfetch-win.zip"
Expand-Archive .\leenfetch-win.zip -DestinationPath .
.\leenfetch-v0.2.1-windows-x86_64.exe
```
> Make sure you're in the same directory as `leenfetch.exe` when running the command.
---
### Install from crates.io
Make sure you have [Rust & Cargo](https://rustup.rs/) installed:
```bash
cargo install leenfetch
````
After that, just run:
```bash
leenfetch
```
If you hit issues with `PATH`, try adding `~/.cargo/bin` to your shell:
```bash
export PATH="$HOME/.cargo/bin:$PATH"
```
---
### π οΈ Manual Installation (Build from Source)
```bash
git clone https://github.com/drunkleen/leenfetch.git
cd leenfetch
cargo build --release
```
Add to PATH:
```bash
cp target/release/leenfetch ~/.local/bin/
```
Then run:
```bash
leenfetch
```
---
## π₯ Using Piped Input
LeenFetch can accept piped input to use as the ASCII logo.
This allows you to create dynamic, fun logos on the fly using other command-line tools.
**Examples:**
```bash
```bash
LeenFetch will detect piped input via `stdin` and render the ASCII art above your system information.
If no piped input is provided, it will fall back to your configured or auto-detected ASCII art.
---
## βοΈ Configuration
On first run, LeenFetch writes a single `config.jsonc` file to your configuration directory:
```bash
# Linux
~/.config/leenfetch/config.jsonc
# Windows
C:\Users\<username>\AppData\Roaming\leenfetch\config.jsonc
```
The file uses JSON with comments (JSONC), so you can keep inline explanations next to your settings. It combines the previous trio of files into a single document with clear sections:
- `flags` β Display and formatting toggles.
- `modules` *(alias `layout`)* β Output order, headings, and custom rows.
- *(optional)* `logo` β Override ASCII art source or padding. Omitted keys fall back to defaults.
### flags section
The `flags` object fine-tunes how each block is rendered. Values shown below match the generated defaults; unset keys fall back to the same defaults internally.
| `ascii_distro` | `"auto"` or distro name | `"auto"` | ASCII art selection. Piped input always overrides this. |
| `ascii_colors` | `"distro"` or comma list of color indices | `"distro"` | Palette for ASCII art and color swatches. |
| `custom_ascii_path` | `""` or path | `""` | Custom ASCII art file. Leave empty for bundled art. |
| `battery_display` | `"off"`, `"bar"`, `"infobar"`, `"barinfo"` | `"off"` | Battery meter style (or disable entirely). |
| `color_blocks` | string glyph | `"β"` | Character(s) used for the 16-color preview. |
| `cpu_brand` | `true` / `false` | `true` | Prefix CPU model with the vendor name. |
| `cpu_cores` | `true` / `false` | `true` | Show total core/thread counts. |
| `cpu_frequency` | `true` / `false` | `true` | Include advertised CPU frequency. |
| `cpu_speed` | `true` / `false` | `true` | Include current CPU speed reading. |
| `cpu_temp` | `"C"` / `"F"` | `"C"` | Temperature unit. Any other value skips conversion. |
| `cpu_show_temp` | `true` / `false` | `false` | Toggle CPU temperature output entirely. |
| `de_version` | `true` / `false` | `true` | Append desktop-environment version. |
| `distro_display` | `name`, `name_version`, `name_arch`, `name_model`, `name_model_version`, `name_model_arch`, `name_model_version_arch` | `"name"` | Level of OS detail shown in the distro line. |
| `disk_display` | `info`, `percentage`, `infobar`, `barinfo`, `bar` | `"info"` | Disk usage presentation for each mount. |
| `disk_subtitle` | `name`, `dir`, `none`, `mount` | `"dir"` | Label used alongside disk usage. |
| `memory_percent` | `true` / `false` | `true` | Add percentage to the memory line. |
| `memory_unit` | `kib`, `mib`, `gib` | `"mib"` | Preferred memory units. |
| `package_managers` | `off`, `on`, `tiny` | `"tiny"` | Package counter verbosity. |
| `refresh_rate` | `true` / `false` | `true` | Append monitor refresh rate where available. |
| `shell_path` | `true` / `false` | `false` | Print full shell path instead of name only. |
| `shell_version` | `true` / `false` | `true` | Append shell version. |
| `uptime_shorthand` | `full`, `tiny`, `seconds` | `"tiny"` | Uptime formatting style. |
| `os_age_shorthand` | `full`, `tiny`, `seconds` | `"tiny"` | OS install age formatting style. |
> βΉοΈ Piped input (for example `fortune | cowsay | leenfetch`) replaces the ASCII logo regardless of `ascii_distro` or `custom_ascii_path`.
Here is a compact example that shortens durations and hides temperature and refresh-rate extras:
```jsonc
{
"flags": {
"uptime_shorthand": "tiny",
"cpu_show_temp": false,
"refresh_rate": false,
"package_managers": "on"
}
}
```
### logo section (optional)
Use the `logo` object to point to custom ASCII art or adjust how the bundled ASCII art is padded. When `type` is `"file"` the `source` path behaves just like `custom_ascii_path`.
```jsonc
{
"logo": {
"type": "file",
"source": "~/.config/leenfetch/branding/about.txt",
"padding": { "top": 2, "right": 6, "left": 0 }
}
}
```
### modules array
The `modules` array (also accepted as `layout`) controls rendering order. Entries can be a literal string (`"break"` inserts an empty spacer) or an object describing a module. Objects accept a `type` (collector name such as `titles`, `distro`, `os_age`, `uptime`, etc.) and optional properties like `key` for the label or `format` for custom text.
```jsonc
{
"modules": [
"break",
{ "type": "custom", "format": "== System ==" },
{ "type": "titles", "key": "User" },
{ "type": "distro", "key": "Distro" },
{ "type": "cpu", "key": "CPU" },
{ "type": "memory", "key": "Memory" },
{ "type": "colors", "key": "" }
]
}
```
Rearrange, duplicate, or remove entries to customize your output. Insert `"break"` wherever you want an empty spacer line.

### How to Edit
- Open `config.jsonc` in your favorite text editor.
- Read the inline comments for a full explanation of every option.
- Change values as you like, save, and re-run `leenfetch` to see your changes.
For advanced details, see the comments in `config.jsonc` or check the [wiki](https://github.com/drunkleen/leenfetch/wiki) (if available).
### CLI overrides
Need a temporary tweak for screenshots or testing? LeenFetch now mirrors most `flags` settings on the CLI so you can adjust the output without touching `config.jsonc`.
- `--config <path>` loads an alternate JSONC file. `--no-config` ignores files altogether and runs with the built-in defaults.
- ASCII controls: `--ascii_distro <name>`, `--ascii_colors <list>`, `--custom_ascii_path <file>`, and `--color-blocks <glyph>`.
- Formatting knobs: `--battery-display`, `--disk-display`, `--disk-subtitle`, `--memory-unit`, `--packages`, `--uptime`, `--os-age`, `--distro-display`, `--cpu-temp-unit`.
- Layout helpers: `--only cpu,memory,shell` renders just the listed modules; `--hide gpu` removes modules from the current layout.
- Boolean toggles come in pairsβuse `--cpu-speed` / `--no-cpu-speed`, `--shell-path` / `--no-shell-path`, `--memory-percent` / `--no-memory-percent`, etc., for quick on/off control of individual fields.
Run `leenfetch --help` to see the complete list of overrides.
