Guile starting state.

Guile starting state.

[R. Clayton]

There appears to be a difference between starting guile (1.6.7 on an x86 debian
testing system) with and without -c:

  $ guile
  guile> (match:substring (string-match "[0-9][0-9]" "bla987"))
  "98"
  guile> ^d

  $ guile -c '(display (match:substring (string-match "[0-9][0-9]" "bla987")))'
  ERROR: Unbound variable: match:substring

  $ 

What is the explanation for the difference?

Notes:

  1 the second example can be fixed with

    $ guile -c '(use-modules (ice-9 regex)) (display (match:substring (string-match "[0-9][0-9]" "blah987")))'
    98
    $ 

  2 ~/.guile does not exist for any of these examples.

In function top-repl, at /usr/share/guile/1.6/ice-9/boot-9.scm:3022:

    (if (provided? 'regex)
	(module-use! guile-user-module (resolve-interface '(ice-9 regex))))

This function is set up for a call in script.c if a -c or -s option is
not used.

top-repl makes this and other modifications to the environment (other
module loadings, signal handlers, etc) before, well, starting the REPL.
