ncdu-zig

Description

Ncdu is a disk usage analyzer with an ncurses interface. It is designed to find space hogs on a remote server where you don’t have an entire graphical setup available, but it is a useful tool even on regular desktop systems. Ncdu aims to be fast, simple and easy to use, and should be able to run in any minimal POSIX-like environment with ncurses installed.

See the ncdu 2 release announcement for information about the differences between this Zig implementation (2.x) and the C version (1.x).

Requirements

  • Zig 0.17
  • Some sort of POSIX-like OS
  • ncurses
  • libzstd

Install

You can use the Zig build system if you’re familiar with that.

There’s also a handy Makefile that supports the typical targets, e.g.:

make
sudo make install PREFIX=/usr
