coreutils in V
This repository contains programs equivalent to GNU coreutils, written in the V language.
Goal
Complete set of coreutils, written as closely as possible to the POSIX spec, with as many GNU extensions as feasible.
We are looking for solid, working implementations of the commands, not 100% 1-to-1 parity, especially not quirks and unintended side-effects.
Layout
Each command has it's own separate subdirectory under src, in case the
implementor wishes to create multiple .v files to implement a command, or add
a README.md specifically for that command.
Developing
Please use the common module for command line/help handling. This will make
the command input/output consistent across the tools.
Building
Running make or v run build.vsh will build all the programs in bin/.
Note: support for access to user account info (via utmp) is limited to POSIX-like platforms. And, so, for Windows, utilities requiring utmp support (uptime, users, who, whoami) are currently skipped during the default build process.
Contributing
Contributions are welcome!
Please only contribute versions of the original utilities written in V. Contributions written in other languages will likely be rejected.
