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 with the sync-stdio feature 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.

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

For now, the viro crate has no actual support for converting environment variables into byte sequences, and the viro binary simply assumes that the conversion is trivial, as it is on POSIX-compliant systems. However, on systems like Windows, a more complicated conversion will be necessary to convert between genuine environment variables and byte slices using a format like WTF-8.

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.
