2010-12-30Less code.David Robillard1-5/+2
git-svn-id: http://svn.drobilla.net/resp/resp@382 ad02d1e2-f140-0410-9f75-f8b11f17cedd

2010-12-28Use fst ("first") instead of head and rst ("rest") instead of tail.David Robillard1-9/+9
git-svn-id: http://svn.drobilla.net/resp/resp@366 ad02d1e2-f140-0410-9f75-f8b11f17cedd
2010-12-28Add quote form, to allow expressions literal symbols and lists (lists not ↵David Robillard1-0/+2
yet implemented). Quoting is a thin lexical concept - a quote of a symbol/list compiles to a symbol/list, rather than interpreted as code (i.e. a variable/call, respectively). A quote of anything else is equivalent to its quotee, e.g. a quote of a String is simply that string (the quote is removed at an early stage by the compiler). There is no Quote data type, or explicit unquoting, or anything like that. git-svn-id: http://svn.drobilla.net/resp/resp@365 ad02d1e2-f140-0410-9f75-f8b11f17cedd

git-svn-id: http://svn.drobilla.net/resp/resp@352 ad02d1e2-f140-0410-9f75-f8b11f17cedd
2010-12-25Simplify let to fn, rather than deal with it through to compilation.David Robillard1-32/+2
The previous implementation of let was a premature optimization intended to make let cheap/free, but screws up closure creation and variable indexing because a new scope is created by something other than fn. Only compile top level expressions to globals (with associated store/retrieve overhead) in a REPL when it is necessary. Add `do' form (ala scheme `begin') to backend (used by `match' simplify). git-svn-id: http://svn.drobilla.net/resp/resp@348 ad02d1e2-f140-0410-9f75-f8b11f17cedd

2010-08-19Generalise `cons': a call to any symbol beginning with an uppercase characterDavid Robillard1-5/+6
(i.e. a type symbol), e.g. (Thing 2), is a call to a type constructor which creates a Tup containing the arguments, with the symbol as the first element in the type expression, e.g. (Thing 2) has type (Thing Int) and compiles to a tuple containing a single Int. The type constructor `Tup' can be used as a `cons' replacement to construct generic tuples. git-svn-id: http://svn.drobilla.net/resp/resp@264 ad02d1e2-f140-0410-9f75-f8b11f17cedd
