I've come up with a solution (a bit inspired by a mail by David
about "mulitple loads of init.(c)sh" ;-) .
First add this at the end (this will tell us if we already go through) :
if ( $?FINKINIT) then
else
setenv FINKINIT
endif
Then, I think there are 2 kind of environment variables :
1) those that can not be modified (for example PATH MANPATH,
if you don't (can't) install create some symlinks), and thus require to
go through only once. Add this around :
if ( $?FINKINIT ) then
else
...
endif
2) those that can be modified (for example CLASSPATH), add
this before :
if ( $?FINKINIT ) then
#already pass at least 1
#restore the user environment variable
if ( $?USER_CLASSPATH ) then
setenv CLASSPATH $USER_CLASSPATH
else
unsetenv CLASSPATH
endif
else
#1st time
#record the user environment variable
if ( $?CLASSPATH ) then
setenv USER_CLASSPATH $CLASSPATH
endif
endif
Did I forgot something ?
Yes I know it's a little lengthy ;-)
