We already have getEnv function.
I think we can postpone design and implementation of a general mechanism
for passing command-line arguments. Now there is a pressing need, for
starting FriCAS from TeXmacs, to do something like that:
* TeXmacs calls
fricas -pre texmacs.input
* fricas script does
export FRICAS_PRE=texmacs.input
* i-toplev.boot calls getEnv("FRICAS_PRE") and, if this variable is set,
reads the file after .fricas.input but before starting the interactive
session
This mechanism is quite useful in itself, without TeXmacs. Any user can
have several files with initial settings for different kinds of sessions,
and using just one init file .fricas.input for temporary needs is
inconvenient because it's too permanent.
What do you think about this specific proposal? Of course, the names (-pre
and FRICAS_PRE) can be replaced by something better.
