bash variable whose value changes dynamically?

I'm a bash newb; just curious if this is possible...

assume i have ~/.bash_profile (mac terminal) w/ following declarations:

export src=~/Developer/src
export myapp=$src/myapp

alias buildapp='build $myapp' # just an example...

this gets loaded when i start up the terminal, and everything's fine.

what i want to do is, later when i switch to a different branch/depot/whatever, i want to type,

export src=~/Developer/temp_src

in the shell, and make $myapp automatically reference the new $src variable...

is this actually possible?

Don't create myapp variable and just use this alias:

alias buildapp='build "$src/myapp"'

Having said that, it is usually better to use a function instead of alias:

buildapp() { build "$src/myapp"; }
