HIGH PRIORITY: * When deferring imports (require) the 'run' actions shouldn't be deferred. FIXME * Optimize and/or in the case of ConditionalTarget or <boolean> target. * properties of symbols * Compilation: not implemented mustConvert restarg * XQuery distinguish qexo: kawa: fn: default function namespaces. * XQuery: Implement/document external functions. * Name mangling, document library modules. * Output formatting of empty arrays? (make-array (shape 0 0 0 3)) Remove pretty-print implementation in slib. Optimize NumberCompare further. document eval methods BRL/KRL: * sitedefs.scm should be loaded * brl function should write to output, not be identity. The default output-pourt shold be re-directed. It should be the same as the ctx.consumer. BEFORE KAWA 1.8? * Resolve whether #!/FILENAME can be followed by embedded options (meta-arg). * CL reader interface * More define-class functionality? * Finish modules: define-module? constructor arguments? * Handle defmacro definition and use in same source file. * load.loadSource if (true) should be if (false). * Implement Scheme API for serialization. * Tail-calls in top-level functions should loop. * Document in internals.html how ModuleMethod/ModuleBody works. Optimize to avoid creating frame classes: If a local variable is captured, and all functions intermediate between the capture site and the definition are call-only functions, and the local variable is never written (except before all calls to these intermediate functions), then add the variable as an extra implicit parameter to thse intermediate functions, instead of storing the variable in a frame. Optimize (call/cc (lambda (exit) ... (exit ...))) when exit is only called, never read, to use BlockExp/ExitExp. Assumes the latter are extended to handle non-local exists - perhaps using the call/cc machinery: Advantage - in many cases call/cc is used to exit a loop, so it can be inlined. Perhaps CallFrame should extend ModuleBody. Should inline when accessing a final static field (using static-field), for int (or shorter) types - but only for "compile-time constants". (Needs checking .class file that field is given ConstantValue.) Starting (emacs) has wrong keybindings unless --elisp is specified. Move kawa.lang.Lambda to gnu.kawa.lispexpr.Lambda. Merge with Elisp version. Remove Scheme.getTypeValue. (define plus +) ... (plus ...) should not inline call to +. Implement IntRange class. Use it to replace Char's hashtable. Replace Char by Character. Modules: * Infer parameter and return types when defaulted and otherwise match method in explicit module-extends or module-interface. compile-file should generate .jar, not .zip. Should perhaps take multiple file names. Update manual to removing .zip references. Binding for imported unknown names (idN$NAME) should not be static! (this) needs to be more general/robust. Start by forcing it to make the generated method non-static. What about 'super' ? Re-store code to check argument count when applyN is involved. (in Compilation and maybe ApplyExp). BindingInitializer.emit: global Environment should be cached TO BE DONE FOR 2.0: Move more of kawa.lang.* to gnu.kawa.reflect and gnu.kawa.*. Calls to setter (as in (set! (...)) should be inlined. 'object': being able to pass constructor arguments. eg., to simulate: new javax.swing.JDialog(myFrame) { public void foo() {} }; Perhaps: (object ((<javax.swing.JDialog> myFrame)) ...) Fix scheme-window in misc.scm. Generate better code for `(and test1 test2 test3)'. [See maybe-report-section in testing.scm] Module compilation: * Allocated selector indexes "densely" within each applyX method of a ModuleBody, so tableswitch gets used, rather than lookupswitch. define-syntax and friends are not properly hygienic when checking literals: symbols listed among the literals lists are matched as raw symbols, rather that checking that the symbol has the same binding, if any, as at the defining site. Complain if syntax or macro is used in other than function-call position. Let LineBufferedReader pos, limit, buffer be private, but provide methods to get/set them. exact->inexact only implemented for RealNums, not other Complex. Fix scheme-window so #!eof closes window. Implement source-filename source-line source-column macros. All function calls in kawa.lib that call standard or library functions should be resolved statically (inlined or direct methods calls). Combine primitive field with record facility and define-class. Provide getopt-long (Guile, check scsh). Implement SwitchExp; use it for Scheme case. Implement full call-cc by re-writing. This would be slower, so should be optional, probably not the default. Implement a pretty-printing AWT container. Complete R4RS procedures. trig functions for complex numbers Complete R5RS number syntax. Implement system open-input-pipe open-output-pipe close-pipe. Add a way to specify a load-path (or maybe just use CLASSPATH?). First seach for loaded files in directory where current file was found. OTHER: Provide a way to compile a Scheme program into an Applet class (with init/start/stor/pain/etc methods). Also provide a stripped down "kawa-run.zip", without eval, load, or compiler. Update to match kawa-tour: Vector -> FVector SyntaxRule.match should use Pattern. Should SyntaxRule inherit from Pattern? Move readSchemeObject readSchemeNumber etc from InPort to new class(es) Parser: class Parser; class SchemeReader extends Parser; // Provides read class SchemeParser extends SchemeReader; // Provides read+rewrite Move Interpreter.syntaxError to Parser. Treat ReadError as SyntaxError. Support warning, error, fatal. Parser accumulates list of syntax errors. When done, if errors or warnings, throw SyntaxErrors. Printing SyntaxError prints error log. Should print warnings in interactive mode, before evaluation. Awkward, because ModuleExp.evalModule is used. Make closure representation consistent with inner classes wrt use of Attributes (for possible improved debugging). Optionally issue a warning if a symbol is rebound. Make kawa.repl -f FILE (or something) work for compiled FILEs. Inline calls to simple methods, especially builtins. Ties in with module specifications (to determine which bindings are builtin). Load should take an optional environment argument. Quantities: Arithmetic involving Units should return Units. Printing a Unit should return something readable, maybe: (quantity->unit 1cm) -> "1cm". while 1cm -> "1.0cm". EVENT CALLBACKS - Proposed design Syntax: (listener (EXTRA-INTERFACE ...) ((METHOD-NAME+ [EVENT-TYPE])+ ARG ACTIONS ...) ...) Example: (invoke component 'addMouseListener (listener ((mousePressed mouseReleases) evt (display (list "mouse pressed or released:" evt)))) This creates a new "listener" instance. The instance has one method for each METHOD-NAME; the method takes a single argument of the specified EVENT-TYPE. The EVENT-TYPE can be left out in the case of standard java METHOD-NAMES; for example if the METHOD-NAME is mousePressed, the implied EVENT-TYPE is <java.awt.event.MouseEvent>. When the method is executed, the actual Event is bound to ARG, and the ACTIONS executed. (The type is ARG is the least common super-type of all the explicit or implicit EVENT-TYPES for corresponding METHOD-NAMES.) The allocated listener instance implements all the interfaces listed in the EXTRA-INTERFACE list; if addition, if an EVENT-TYPE was implied, the corresponding Listener interface is also implied. (For example a METHOD-NAME of mousePressed implies an EVENT-TYPE of <java.awt.event.MouseEvent>, and hence an interface of <java.awt.event.MouseListener>.) New syntax: (listener [(EXTRA-INTERFACE ...)] ((METHOD-NAME ... EVENT-ARG-NAME [:: EVENT-TYPE]) ...)) SYMBOLS If we have pre-process environments, (define exit ...) should only re-define exit in the current environment, not all. JDK1.2 TASKS - THINGS TO DO ONCE WE REQUIRE JAVA2 Rewrite (make-temporary-file) to use File.createTempFile. Possibly replace GuiConsole to use JTextPane (or gnu.jemacs.buffer.Window). JEMACS clean up function-binding hacks vertical-motion Make it so that JEmacs does not require Swing. There is a start in that gnu.jemacs.buffer mostly contains toolkit-independentcode, and gnu.jemacs.swing contains Swing-specific implementations. This separation shoudl be finished, and we should add one or more implementation on other toolskits: - using Gnome2 (http://developer.gnome.org/doc/API/2.0/gtk/textwidget.html) text widgets with Pango (http://developer.gnome.org/doc/API/2.0/pango/); - one that uses the SWT toolkit (http://www.eclipse.org/articles/) that is part of the Eclipse project (http://www.eclipse.org); - one that uses plain AWT; - and one that works on plain terminals, perhaps using charva (http://www.pitman.co.za/projects/charva/). It is important that JEmacs be able to run well using Free Software only, and it cannot do hat as long it depends on Swing, until there is a free re-implementation of a suitable Swing subset. Note that the Buffer class should be a pure "model" which is toolkit independent: we want to be able to display the same buffer in both a Swing Window and a telnet window at the same time. The JEmacs widgets should be integrated into the gnu/kawa/slib/gui.scm design. Should implement Common Lisp-style "type specifiers" and declarations. This would make it practical to write-lower level code that calls Java methods directly in ELisp (and Common Lisp), without having to use Scheme.
