Hmm, how is this different from my existing exec-path-from-shell package? As far as I can tell, they both provide the same functionality.

[purcell]

(Specifically, exec-path-from-shell-copy-env seems just like shellenv: https://github.com/purcell/exec-path-from-shell/blob/master/exec-path-from-shell.el#L142)

[zonuexe]

I thought that there should be the person of the thought same as me, but wrote shellenv because I was not able to discover it. Its original was a small cord snippet. https://gist.github.com/zonuexe/3792841

shellenv execute a shell of path which a user ordered if I give a difference with exec-path-from-shell daringly and is to be able to acquire every environment variable. (shellenv/setenv "�PAGER")

I cannot judge which script shows good performance.

[purcell]

Yes, exec-path-from-shell does the same thing:

(exec-path-from-shell-copy-env "PAGER")

but it also allows multiple values to be set using just a single "sh" process:

(exec-path-from-shell-copy-envs '("PATH" "MANPATH" "SSH_AUTH_SOCK" "PAGER")) ;; => Only calls "sh" once

Additionally, shellenv fails in the following case:

export FOO1="FOO\nBAR"

then

(shellenv/.getenv "FOO1") ; => "FOO\\nBAR"

so the newline wasn't preserved.

If it's possible for you to use exec-path-from-shell, I think it would be less confusing for users than to introduce a second similar library.

Hey @syohex and @tom-tan, you've presumably seen both shellenv and exec-path-from-shell: any comments on this discussion?

[tom-tan]

Hi @purcell and @zonuexe,

I find that exec-path-from-shell does not customize the shell to get PATH.
Is it possible to customize it?
Some people uses different shells inside/outside GNU screen.

[purcell]

Yes, that customisation would be easy to provide.

But in fact, if you use a different shell from within Emacs, you should probably just (setenv "SHELL" "/bin/someshell"), in which case exec-path-from-shell will do the right thing.

@purcell I think exec-path-from-shell is better than shellenv.
exec-path-from-shell provides all feature of shellenv and exec-path-from-shell has
good documentation.

Going to close this. Re-open if anyone is pissed.
