Work around a Zig ReleaseSafe mode performance regression

Yorhel authored 2 years ago

With a little help from IRC:

<ifreund> Ayo: its probaly stupidly copying that array to the stack to do the
          safety check, pretty sure there's an open issue on this still
<ifreund> you may be able to work around the compiler's stupidity by using a
          pointer to the array or slice or something
<Ayo> ifreund: Yup, (&self.rdbuf)[self.rdoff] does the trick, thanks.
<ifreund> no problem! should get fixed eventually

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 0.9.0 or 0.9.1
Some sort of POSIX-like OS
ncurses libraries and header files

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
