impromptu

Spawn $EDITOR to update an association list for CLI scripts.

Overview

[procedure] (edit-properties alist)

Formats alist to a temporary file and spawns the user's preferred editor on it. If the editor exits with a zero error level, the file is parsed back into a new association list having keywords for keys and returned.

If the editor exits with a non-zero error, edit-properties returns #f.

The editor is sought in the following order:

Format

 
'((User: . "joeblack")
  (Description: . "Joe Black, an old friend of the family, is\na short, stocky fellow with greased black hair."))

Produces the following file:

 :User: joeblack
 :Description:
 Joe Black, an old friend of the family, is
 a short, stocky fellow with greased black hair.
