lsv - Vlang implementation of ls

lsv is a modern alternative to ls in the spirit of exa, eza, lsd, pls, natls, ls-go and others.

Border format with header option

Features

• Single binary with no external dependencies!
• Not written in Rust 😮 (see below)
• Color output based on LS_COLORS
• Table format (long format)
• Column Headers (long format)
• Blocked output (long format)
• Icons
• Checksum (md5, sha1, sha224, sha256, sha512, blake2b)
• Friendly file sizes and dates
• Nearly as fast as GNU ls
• Robust recursion. Try lsv -R /
• Options similar to ls

  -u                        no sorting

  --after <string>          after modified time <string>

  --after-change <string>   after change time <string>
  --before <string>         before modified time <string>
  --before-access <string>  before access time <string>
  --before-change <string>  before change time <string>

                            where time <string> is an ISO 8601 format.
                            See: https://ijmacd.github.io/rfc3339-iso8601

  --ignore <string>         ignore glob patterns (pipe-separated)

The -c option emits color codes when standard output is
connected to a terminal. Colors are defined in the LS_COLORS
environment variable.

Why?

It started with writing a ls implemention for the V Language CoreUtils project. Coreutils is a reimplementation of the POSIX and GNU utility programs written in the V Language. Everything was going fine until I started having too much fun and down the, "Rabbit Hole" I went.

What's this V language? You can read about it here, but the short version is it is a simple, fast, safe, compiled language for developing maintainable software. I mentioned lsv is not written in Rust. I'm not trashing Rust. Rust is obviously a robust and popular language. However, it's a steep climb to get up to speed and requires a fair bit of cognitive load to use it well.

V is the opposite. It has many of the same safty features of Rust, but without the cognitive over head. It's simple, straightfoward syntax makes it a breeze to write. Builds happen in milliseconds, not minutes and hours. You don't need any special build tools like Gradle.

Finally, take a look at the lsv code base. The entire code base is 2K lines 🧐. Furthermore, the implemention is straightforward. No threading, coroutines or fancy memory management. Even if you don't know V, I'm betting you will understand the code.
