I am wotking on adding "a Scope class to make it easier to plugin custom scopes" (as per the TODO list).
I have tought that taking the variable-handling stuff out of JellyCopntext could be a Good Thing, since that class seems to already have a whole bunch of responsibilities, so I started to code a replacement for that part of JellyContext instead of a simple "holder" scope with copyToContext(JellyContext) and copyFromContext(JellyScope) methods. While doing so I bumped into JellyContext.isExport()... :) Right now the behaviour of a jelly context with export=true is to live as a parasitic of its parent and to define its own variables into the parent scope (context). The behaviour is now such as: 1) //parent scope // no 'foo' defined here { // child scope String foo = "bar"; } // use a in parent scope System.out.println(foo); 2) //parent scope String foo = "asdf"; { // child scope String foo = "bar"; } // use a in parent scope System.out.println(foo); would both output "bar" Is this intended behaviour, or was the exporting stuff intended only to allow for stuff like //parent scope String foo = "bar"; { foo = "asdf"; } System.out.println(foo); to output "asdf"? (or to prevent it from doing so if export=false) ======== BTW: a) Would features such as: - knowing whether a certain variable (variable name) is visible from a given scope - knowing if a certain variable has been initialized - checking for variable names to be "valid" (eg: w/o whitespace, non-empty, non-null...) be welcome in a scope implementation? b) Would introducing a variable (meaning "reference") class be welcome? IMO it could be nicer to have persistent variables instead of (or in addition to) persistent scopes.
