viro

Loads your environment so you don't have to.

Offers a data structure for serializing and deserializing environment variables, to allow for easy loading of /etc/profile scripts in non-POSIX shells like fish. The viro binary is only available for unix-based systems at the moment; see the "Roadmap" section of this README for details.

License

Available via the Anti-Capitalist Software License for individuals, non-profit organisations, and worker-owned businesses.

Installation

First, build viro for your system and install it in /usr/bin, alongside the viro-profile script.

Depending on whether you want to use systemd or no d, merge the /usr provided in either systemd/usr or nod/usr with your own. If you use Arch Linux, a version of the systemd files is offered as a PKGBUILD in the pkg directory.

Usage

Because bash does not have a standardized config directory, you will need to source the scripts in /usr/share/bash/bashrc.d in order to make this work. If you chose to use systemd, you must also enable the profile.service for your user.

Roadmap

The viro crate has been fully ported to using OsStrings instead of byte sequences, meaning that it in theory should be portable to Windows. However, after doing this, I decided that I'm not going to simp for Microsoft, and did not actually implement a Windows version.

The main issue is that it should be outputting "wide character" strings in all cases on Windows, but Rust specifically takes steps to ensure that stdio transforms UTF-8 output into what Windows expects, and doesn't actually convert all WTF-8 OsStrings into wide characters. So, special code would have to be written using the Windows API to properly account for this.

Additionally, there are currently no attempts to escape \x3D (equals sign) and \x00 (NUL) bytes when outputting variables, and this simply alters the output. A future version of this crate will want to offer these, but I have no plans to implement this at the moment.
