关于 shell：Emacs 外部进程调用期间的临时修改环境


Temporary Modified Environment during External Process Call from Emacs

server-with-environment 看起来很有前途。

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'.
