## 项目历史与用法

lsr is a Zig implementation of `ls(1)` that uses io_uring where possible to reduce syscall overhead. The official README calls it `ls(1)` but with io_uring, and the author's write-up describes it as an exercise in syscall golf.

### 项目历史

The project was publicly introduced by Tim Culverhouse in a 2025-05-06 write-up. The author explains that lsr uses the ourio library and io_uring to batch I/O work such as opening directories, reading local time, user and group data, and performing stat-like calls.

The official repository is hosted on Tangled. Its README documents Zig 0.14.0 build/install instructions, a manpage install target, and common `ls`-style display options including long output, columns, sorting, colors, hyperlinks, icons, and directory grouping.

### 采用历史

lsr is young and specialized, but it already reached Homebrew and Nix in the supplied package facts. Its adoption is primarily among users interested in Linux filesystem performance, Zig tooling, and modern `ls` alternatives.

### 使用方式

Typical usage mirrors `ls`: run `lsr [options] [path]`. The README documents options for one-entry-per-line output, hidden files, columns, color mode, directories-first grouping, OSC 8 hyperlinks, icons, long output, reverse sort, and modification-time sorting.

The author's benchmarks compare lsr against GNU ls, eza, lsd, uutils ls, and BusyBox ls on directories from 10 to 10,000 files. The README notes that lsr works on macOS and BSD too, but the io_uring syscall batching benefits are Linux-specific.

### 为什么软件包爱好者会关心

lsr is package-nerd interesting because it revisits the most ordinary Unix command with a very modern Linux I/O interface. It is not a general replacement for mature `ls` implementations yet, but it is a compact demonstration of where syscall batching can matter in command-line filesystem tools.

### 时间线

- 2025: Author publishes the lsr write-up and benchmarks.
- 2025: Tangled repository documents version 0.1.0 benchmark data.
- 2026: Supplied package facts list Homebrew and Nix packaging.
