Gloss is a set of enhancements to the Unix command line experience. It consists of shell configurations and small utilities. It currently targets modern macOS and Fedora Linux.

• Python from source via github.com/gwk/inish.
• Pithy: github.com/gwk/pithy.

• Run sudo make install-sys or sudo install/gloss-install-sys.py
• Run make install-user or install/gloss-install-user.py
• Run make install-vscode or install/gloss-install-vscode.sh
• Adjust your .zprofile, .zshenv, .zshrc as necessary; see dotfiles/ for the minimal examples of what to source.

Gloss establishes a consistent PATH ordering in zsh/paths.zsh.

macOS /usr/libexec/path_helper reorders PATH and MANPATH to force system paths first. This happens after .zshenv but before .zprofile. It first adds every line listed in /etc/paths, followed by every line listed in each file in /etc/paths.d/*, and then appends any remaining preexisting entries. /etc/zprofile sources ~/.zshenv and ~/.zprofile for login shells, after path_helper has run. Therefore /etc/paths.d cannot express the desired ordering, so gloss does not use it. Instead, paths.zsh is sourced from env.zsh (i.e. ~/.zshenv) for non-login shells, and from profile.zsh (i.e. ~/.zprofile) for login shells, after path_helper has run. Both cases source it exactly once, after any reordering, so all shells end up with the same PATH.

gloss-install-sys.py also writes /etc/sudoers.d/gloss-secure-path, setting the sudoers secure_path to the same ordering restricted to root-owned, non-group/other-writable directories.
