Commit Message

Change to split namespace by package

Previously, Common Lisp pacage is used only for grouping variables and
functions. Then, when they are output as JavaScript code, the
namespace is not split.

This commit introduces namespace also in JavaScript code by using
closure. But some (dirty) hacks were required.

First, to refer un-exported symbols, each package has a "_internal"
member, then internal symbols can be referred as
"<package>._internal.<symbol>". In addition, to identify un-imported
symbol, ps:symbol-to-js-string is overwritten.

Second, to send type-specifier to other package, quote is removed if
it is attached to a type-specifier symbol. In Common Lisp,
type-specifier can be specified using symbol, but it is converted to
just a string by Parenscript. In other words, the information of
package is lost. So in other package, we can no longer extract the
type. To achieve this, "quote" in Parenscript is overwritten.

Note: Variable, function and type-specfier are in a same namespace in
a package unlike Common Lisp namespace.

Note: Parenscript has a namespace system. It splits namespaces by
adding prefix to all symbols in the package. But I wanted to achieve
more Common Lisp like one that has symbol importing and exporting.
