I don't know how much this satisfies your requirements, but I do
something on the
following lines (And given your exposure to mylyn, you can think of
expanding this
further - my requirements, and hence the solution, are simple):
I create various "contexts" and set my env-variables to specific
values for a given
context. Let's say, I have contexts A and B to work in, and I have corresponding
directories A and B in my $HOME. Then I define functions in my shell
which set up
some variables based on the context I am requesting ($HOME, $PATH, $CVSROOT,
$HISTFILE, $PS1 etc.) - and have a 'revert' function (I call 'b2n' -
back-2-normal) which
resets all variables to the original ones).
Nothing sophisticated, but works for me!
(The following goes into your shell's config file)
<script-snippet>
if [ -z "$OLDHOME" ]; then
export OLDHOME=$HOME
fi
if [ -z "$OLDPATH" ]; then
export OLDPATH=$PATH
fi
if [ -z "$OLDLD_LIBRARY_PATH" ]; then
export OLDLD_LIBRARY_PATH=$LD_LIBRARY_PATH
fi
if [ -z "$OLDCVSROOT" ]; then
export OLDCVSROOT=$CVSROOT
fi
if [ -z "$OLDPS1" ]; then
export OLDPS1=$PS1
fi
if [ -z "$OLDPKG_CONFIG_PATH" ]; then
export OLDPKG_CONFIG_PATH=$PKG_CONFIG_PATH
fi
if [ -z "$OLDCLASSPATH" ]; then
export OLDCLASSPATH=$CLASSPATH
fi
b2n ()
{
export HOME=$OLDHOME
export PATH=$OLDPATH
export LD_LIBRARY_PATH=$OLDLD_LIBRARY_PATH
export CVSROOT=$OLDCVSROOT
export PS1=$OLDPS1
export PKG_CONFIG_PATH=$OLDPKG_CONFIG_PATH
export CLASSPATH=$OLDCLASSPATH
cd
}
contextA()
{
export HOME=$OLDHOME/A
....
cd
}
</script-snippet>
HTH.
