Temporary Modified Environment during External Process Call from Emacs

Is there a convenient and functional (with-...-like) way of temporary modifying environment variables when using shell-comand or start-process?

Thanks in advance, Per

Solution

  • server-with-environment looks promising.

    server-with-environment is a Lisp macro in `server.el'.

    (server-with-environment ENV VARS &rest BODY)

    Evaluate BODY with environment variables VARS set to those in ENV. The environment variables are then restored to their previous values.

    VARS should be a list of strings. ENV should be in the same format as `process-environment'.
