setting enviromment variable

setting enviromment variable

[henry atting]

Hi,

setting environment variables does not work anymore.
I do it like this:

;; ledger file variable
(setenv "LEDGER_FILE" (concat (getenv "LEDGER_FILE") "~/ledger/ledger.dat"))
;; printer variable
(setenv "PRINTER" (concat (getenv "PRINTER") "HL2030"))

Evaluating produces:

"~/ledger/ledger.dat~/ledger/ledger.dat~/ledger/ledger.dat~/ledger/ledger.dat"
"HL2030HL2030HL2030HL2030"

Hence I cannot print or use ledger from the eshell command line:

While parsing environment variable option
'LEDGER_FILE=~/ledger/ledger.dat~/ledger/ledger.dat': Error: The ledger
file '/home/atting/ledger/ledger.dat~/ledger/ledger.dat' does not exist
or is not readable

(GNU Emacs 23.1.50.1)

What this does is that it adds to what is already stored in the
environment variable. If you just want to set the value, you'd do it
like this:

  (setenv "LEDGER_FILE" "~/ledger/ledger.dat")
  (setenv "PRINTER" "HL2030")

Adding to an environment variable only makes sense for PATH and
friends.

Looks like the code ran four times. 8-)

HTH,

Or existed as a triple before and did not get cleared as a single by  
the code...

Yes, thank, `setenv' works fine. 
Unfortunately it is not as simple. Adding an environment variable
with `concat' worked for a rather long time because emacs seems to ignore
these settings outside emacs in ~/.zshrc (which is not surprising).
But, as far as I can see, out of the blue emacs makes use of them now,
so they are doubled or quadruplicated or what ever.

Since today AucTeX ignores the PATH to latex/pdflatex. I never had to
set the PATH manually in ~/.emacs. I wonder if 

(setenv "TEXINPUTS" ":$HOME/texlive/2008/bin/i386-linux//")

would be the appropriate way. Seems so for me but it does not work
anyway.
