Yet, another ls-like util that is **not** trying to replace `ls`.
Cerium gets inspiration from similar tools such as lsd and eza, but with a small difference: It aims to stay small by avoiding features that introduce heavy dependencies while doing what a tool of its kind is supposed to do... list files and directories.

## Installation
### Quick Install (with Cargo)
```shell
# Standard installation with all features
cargo install cerium --all-features
# Minimal installation
cargo install cerium
# Specific features
cargo install cerium --features magic
cargo install cerium --features checksum
```
### Build from Source
```bash
# Clone the repo
git clone https://codeberg.org/rly0nheart/cerium.git
# Move to cerium directory
cd cerium
# Build and install: This will build cerium with all its features
make install
```
## Features (optional)
### Magic
Content-based file type identification using libmagic. Shows actual file types regardless of extension.
**Requirements:** libmagic library (`scripts/install-libmagic.sh`)
```bash
ce --magic
```
### Checksum
Calculate file checksums with multiple algorithms.
**Supported:** `crc32`, `md5`, `sha224`, `sha256`, `sha384`, `sha512`
```bash
ce --checksum sha256
```
## Usage
```
ce [OPTIONS] [PATH]
```
### Display Options
```bash
-1, --oneline One entry per line
-l, --long Long format (permissions, user, group, size, modified)
-t, --tree Tree view
-H, --column-headers Show column headers
```
### Filtering
```bash
-a, --all Include hidden entries
-d, --dirs Directories only
-f, --files Files only
--find <QUERY> Search for entries that match a query
--hide <ENTRIES> Exclude specific entries (comma-separated)
--prune Omit empty directories
```
### Metadata Display
```bash
-p, --permission File permissions
-u, --user Owner
-g, --group Group
-s, --size File size
-m, --modified Modification time
-c, --created Creation time
--accessed Access time
-i, --inode Inode number
-b, --blocks Block count
--hard-links Hard link count
--acl ACL indicator
-x, --xattr Extended attributes
--mountpoint Mount point
```
### Sorting & Traversal
```bash
--sort <BY> name, size, created, accessed, modified, extension, inode
-r, --reverse Reverse order
-R, --recursive Recurse into subdirectories
-S, --true-size Calculate actual directory sizes
```
### Formatting
```bash
--date-format <FMT> locale, human, timestamp
--number-format <FMT> human, natural
--ownership-format <FMT> name, id
--permission-format <FMT> symbolic, octal, hex
--size-format <FMT> bytes, binary, decimal
```
### Appearance
```bash
-C, --colo[u]rs <WHEN> always, auto, never
-I, --icons <WHEN> always, auto, never
-Q, --quote-name auto, double, single, never
```
## Examples
### Basic Operations
```bash
ce -la # Long format, all files
ce -t # Tree view
ce -lt --icons=always # Tree with metadata and icons
ce --find=*.rs --sort=size -r # Find Rust files, sort by size
```
### Metadata Inspection
```bash
ce -pugm --date-format=humanly # Permissions, ownership, modified date, human dates
ce -i --hard-links --sort=inode # Inodes and hard links
ce --acl -x # ACLs and extended attributes
ce -lb --block-size # Block usage
```
### Advanced Usage
```bash
ce --magic --checksum sha256 # Type detection + checksums
ce -RS --true-size # Recursive with actual directory sizes
ce --hide=target,node_modules -t # Tree excluding build artifacts
ce --permission-format=octal -p # Octal permissions
ce --ownership-format=id -ug # Numeric UIDs/GIDs
```
### Combined Operations
```bash
ce -laH --date-format=humanly --size-format=binary
ce --find=.pdf --checksum md5 --sort=modified -r
ce -t --prune --hide=.git,target --icons=always
```
## Themes
Cerium supports customisable themes via a TOML configuration file. By default, it uses the Gruvbox colour palette.
### Quick Start
```bash
# Apply a pre-made theme
cp themes/dracula.toml ~/.config/cerium.toml
```
### Available Themes
See [`themes/README.md`](themes/README.md) for the full list of pre-made themes, installation instructions, and customisation guide.
