Harald,
There is this function:
substitute-in-file-name:
Substitute environment variables referred to in STRING.
A $ begins a request to substitute; the env variable name is
the alphanumeric characters after the $, or else is surrounded by braces.
If a ~ appears following a /, everything through that / is discarded.
On VMS, $ substitution is not done; this function does little and only
duplicates what expand-file-name does.
which should solve your problem:
(setq load-path (cons (substitute-in-file-name "$HOME/emacs") load-path))
=> ("/user/lewis/emacs" "/usr/stanford/lib/gnuemacs/lisp")
-Bil

Heuer (ima!haddock!karl or karl@haddock.isc.com), The Walking Lint ---------------------------------------------------------------- ---------------------------------------------------------------- My first question: Why is this a "better solution"? My second question: I am just starting to learn some of this GNU .el stuff -- I'd looked a bit into the UniPress .ml stuff. Since there is not a 'tutorial' on the language, I'd be interested to hear from some experienced .el-programmers. All of the following were proposed as solutions to the original problem. Are any of the following good/bad, correct/incorrect, efficient/inefficient, etc? (setq load-path (cons (format "%s/.emacs" (getenv "HOME")) load-path)) (setq load-path (concat (getenv "HOME") "/elisp-library") load-path) (setq load-path (cons (substitute-in-file-name "$HOME/emacs") load-path)) (setq load-path (cons (expand-file-name "~/lib/emacs") load-path)) Sorry I couldn't give specific credit to the authors of the lines -- you can look them up for yourself in previous net-news articles. My third question: Is it true that there is no 'tutorial' on the elisp language? Thanks in advance for any help -- I'm sure that others will appreciate it also.
