Subject: bug#19251: 24.4; LANG not applied in shell command
Date: Tue, 02 Dec 2014 10:57:21 +0100 [thread overview]
Message-ID: <867fyatlvi.fsf@example.com> (raw)
Hello,
I'm trying to automate the update of some Git project with:
--8<---------------cut here---------------start------------->8---
(defun config-update ()
"Update config."
(interactive)
(message "Updating config...")
(cd config--directory)
(let ((ret (shell-command-to-string "LANG=en_US git pull --rebase")))
(if (string-match "Already up-to-date." ret)
(message "Configuration already up-to-date.")
(princ ret)
(message "Configuration updated."))))
--8<---------------cut here---------------end--------------->8---
On my machine (Windows 8 with Cygwin), that works as expected.
On one friend's machine (some Linux variant), whatever the answer of
`git pull' (something new or nothing new), he will always have the
impression that the project has just been updated:
┌────
│ Updating config...
│ La branche courante master est à jour.
│
│ Configuration updated.
└────
This is because my function looks for the string "Already up-to-date" in
Git's output, and his output is in French -- while I forced LANG to
en_US.
So, why is LANG not respected in `shell-command-to-string'?
Best regards,
Seb
