;;; Commentary:

;; This file can be used to set up environment variables for Guile-XOSD
;; inside Emacs.  Shell "pre-inst-env" script may be useful, but I
;; prefer to work with Guile using Geiser.  So I just evaluate the
;; contents of this file (M-x eval-buffer) and that's it!: when I do
;; "M-x run-guile", I can ",use(xosd)" there and work with it.

;;; Code:

(let ((src-modules   (expand-file-name "modules" "@abs_top_srcdir@"))
      (build-modules (expand-file-name "modules" "@abs_top_builddir@"))
      (guile-path    (getenv "GUILE_LOAD_PATH"))
      (guile-cpath   (getenv "GUILE_LOAD_COMPILED_PATH")))
  (setenv "GUILE_LOAD_PATH"
          (let ((base (if guile-path
                          (concat build-modules ":" guile-path)
                        build-modules)))
            (if (string= src-modules build-modules)
                base
              (concat src-modules ":" base))))
  (setenv "GUILE_LOAD_COMPILED_PATH"
          (if guile-cpath
              (concat build-modules ":" guile-cpath)
            build-modules))
  (setenv "GUILE_XOSD_LIBDIR" (expand-file-name "src/.libs"
                                                "@abs_top_builddir@"))
