Refold

refold is a commandline tool for performing text-wrapping, similar to unix fold. Unlike fold, refold will recombine lines before performing line-wrapping, and it will automatically detect line prefixes.

Comparison to fold

	refold	unix fold
Rewrapping	Yes	No
Line prefix support	Yes	No
Line endings	LF and can auto detect CRLF	LF only
Default wrapping	Soft via Unicode splittable property	Hard
Hard wrapping	Yes	Yes
Soft wrapping	Yes	Yes*

*: fold leaves trailing spaces and can only split ASCII space-separated words.

Example:

refold --spaces --width=100:

/// I'd just like to interject for a moment. What you're refering to as Linux, is in fact, GNU/Linux,
/// or as I've recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the
/// GNU corelibs, shell utilities
/// and vital system components comprising a full OS as defined by POSIX.

Installing

Cargo (most platforms)

1. Install Cargo.
2. Run cargo install refold.

Binaries

Binaries for arm64 and x86_64 can be found in the releases section of the github.

These are statically linked, so they should run on pretty much any linux distribution including NixOS and Alpine.

Additionally, these binaries are packaged in the following formats:

• APK
• DEB
• RPM

Nix

Alternatively, a Nix package can be found in the releases section. Unfortunately, refold will not be updated automatically when using this method.

1. Download refold.nix from the Releases page.
2. Add (pkgs.callPackage /PATH/TO/REFOLD.NIX {}) to your configuration.nix file under environment.systemPackages, users.users.YOUR_USERNAME.packages, or in any other place that you can list packages.
