system-environment

• Introduction

Introduction

This package helps making environment variables defined outside of Emacs available inside. Quite often some system component - like a shell, or systemd user session - is configured with correct environment variables, but the launcher does not have a complete set, resulting in Emacs inheriting a bad copy.

Example for Linux with systemd user session, exporting everything but the variables listed here:

(system-environment-import-from-command "systemctl --user show-environment"
                                        '("DISPLAY" "HOME" "LOGNAME" "USER") t)))

Example for Windows, importing only the variables listed here:

(system-environment-import-from-async-command
 "powershell -Command Get-ChildItem Env:|Foreach-Object {'{0}={1}' -f $_.Key,$_.Value }"
 '("GIT_SSH" "HOMEDRIVE" "HOMEPATH" "GOPATH" "PATH" "SSH_AUTH_SOCK"))

Example for MacOS (or any other system with zsh), importing only the two variables listed:

(system-environment-import-from-command "zsh -i -c env" '("PATH" "SSH_AUTH_SOCK") nil nil t)
