[Able-devel] new: debugger, and re-open on restart
by Daniel Herring 16 Nov '11

16 Nov '11

Hi all, The git master branch now has support for invoking the native CL debugger. It will also re-open files if you restart ABLE within a CL session. https://github.com/dherring/able https://github.com/dherring/able/zipball/master By default the debugger is bound to <Control-D>. (open to recommendations for a better binding) Pressing this key will suspend ABLE's event loop and return control to the normal CL prompt (e.g. the SBCL terminal or Slime's debugger). Selecting the RETURN-TO-ABLE restart (or "Abort handling Tk event") will return control to the ABLE window. Most other restarts will result in ABLE exiting. Tested on SBCL/linux, under a plain shell and under Slime. Please let me know how this works for you. Later, Daniel

[Able-devel] updates in git master

Hi all, I just pushed a few improvements to git master (github.com:dherring/able.git). - fix printing of floating-point numbers under SBCL - list key bindings in the menus and there were a few more last week. Later, Daniel

[Able-devel] Question about the [ key binding
by dherring＠tentpost.com 07 Nov '11

07 Nov '11

Hi all, The current default in ABLE is for the left bracket key, [, to insert a pair of matching parentheses, #\( #\). This is unexpected behavior for most users, as is the need to press C-[ to insert a #\[. Would any users mind if the default was switched so the [ key inserts a #\[ ? Thanks, Daniel

[Able-devel] ABLE does not compile out of the box
by Eduardo Costa 03 Nov '11

03 Nov '11

Windows, ltk-0.96. BTW, I teaching Common LISP for engineers, and using ABLE/SBCL. However, since ABLE does not compile out of the box, I am distributing binaries to the my students. It would be nice if you people could fix the compilation problems that I describe below. 1 -- able-0.21, SBCL 1.0.52, ltk-0.96, cl-fad-0.6.4, trivial-gray-streams-2008-11-02 2 -- I tried to compile and load the programs: * (require 'asdf) ("ASDF") * (asdf:oos 'asdf:load-op :able) ... debugger invoked on a ASDF:COMPILE-ERROR: Error while invoking #<COMPILE-OP NIL {24D9CEB9}> on #<CL-SOURCE-FILE "able" "utils"> 3 -- I substituted sb-introspect:function-lambda-list for all instances of sb-introspect:function-lambda-list I also corrected the obvious error (format nil "1.0" temp) 4 -- I repeated step 2. * (require 'asdf) ("ASDF") * (asdf:oos 'asdf:load-op :able) Compilation was uneventful, but I got a runtime error ---- Invalid intialization arguments: :PADY, :PADX, :CONTAINER In main.lisp, I replaced (setf *editor-frame* (make-instance 'ltk:frame)) for (setf *editor-frame* (make-instance 'ltk:frame :container nil :padx 1 :pady 1)) I compiled the editor once more: * (require 'asdf) ("ASDF") * (asdf:oos 'asdf:load-op :able) Again, the compilation was uneventful, but... Invalid initialization arguments :PADY, :PADX I substituted (setf *listener* (make-instance 'listener )) for (setf *listener* (make-instance 'listener :padx 1 :pady 1)) This time the error was Tcl/Tk error: unknown option "-background" I commented one line at the end of the controls.lisp file: (defmethod initialize-instance :after ((sb statusbar) &key) (setf (label sb) (make-instance 'ltk:label :master sb :font *buffer-font*)) ; (ltk:configure sb :background *highlight-background*) (ltk:configure (label sb) :background *highlight-background* :foreground *highlight-text*) (ltk:pack (label sb) :side :left :pady 1 :padx 5 :fill :both)) Now, ABLE works perfectly well. My suggestion is that you modify the sources, so that the user get an uneventful compilation. In the mean time, I would like to know whether I can post my modified sources in my son's website, so my students will have a working copy of ABLE. Of course, I will remove it from my site as soon as the official distribution is fixed.

[Able-devel] Pro tempore fix
by Eduardo Costa 30 Oct '11

30 Oct '11

As I told before, ABLE crashes whenever there is a space between an open parenthesis and a token. For instance (defvar xxx '( abc d e f)) causes a TK crash.A quick fix is to add a condition that deals with an empty token into the get-indent-level macro (see macro.lisp). Thus (defmacro get-indent-level (token) "Deduce how much to indent based on the token supplied. The user can supply their own indentation rules in the configuration file." `(cond ((< (length ,token) 1) 1) ((equal (char ,token 0) +lparen+) 1) ((equal (length ,token) 1) 3) ,@(mapcar #'(lambda (rule) `((equalp ,token ,(car rule)) ,(cdr rule))) *indentation-rules*) (t 2)))

[Able-devel] A bug in ABLE
by Eduardo Costa 29 Oct '11

29 Oct '11

Whenever there is a spac after an open parenthesis, one gets a TK error. For instance, try and type the following definition: (defvar xxx '( abc x y z )) Leave a space between the open parenthesis and abc. The Tk message is: Index 0 out of bounds for (SIMPLE-ARRAY CHARACTER(0)), should be nonnegative and <0. I guess the problem has to do with the token coloring algorithm.

Re: [Able-devel] No :padding Initarg In LTK's Quicklisp
by Matt Niemeir 27 Feb '11

>Thanks for sharing this information. Could you ask quicklisp to apply >this as a local patch or to upgrade their packages to be compatible? > >How does one find the exact versions used by quicklisp? i.e. tarball url >or repository and version number, local patches, etc. > >- Daniel I was mistaken; I didn't get able from quicklisp. I had the git master branch from common-lisp.net. Able isn't in quicklisp. The able 0.21 release is actually using the :padx 1 :pady 1 version, so it works for me without the edit. Quicklisp is serving ltk-0.91, which matches the version at http://www.peter-herth.de/ltk/. The most detailed list of quicklisp packages seems to be /www.quicklisp.org/beta/releases.html, or you can use (ql:system-apropos "project") if you use quicklisp. For completeness, here is the error I get in ccl on linux when create-widgets uses :padding internally. An error of type SIMPLE-PROGRAM-ERROR has occured: :PADDING is an invalid initarg to INITIALIZE-INSTANCE for #<STANDARD-CLASS LTK:FRAME>. Valid initargs: (:GRID :PLACE :PACK :WIDTH :VISUAL :TAKEFOCUS :RELIEF :PADY :PADX :HIGHLIGHTTHICKNESS :HIGHLIGHTCOLOR :HIGHLIGHTBACKGROUND :HEIGHT :CURSOR :CONTAINER :COLORMAP :CLASS :BORDERWIDTH :BACKGROUND :NAME :MASTER :PATH :INIT-COMMAND).

[Able-devel] No :padding Initarg In LTK's Quicklisp Distribution
by Matt Niemeir 25 Feb '11

25 Feb '11

Hello, After loading able with quicklisp, able:start gives an error about a :padding initarg. The version of LTK that quicklisp distributes appears to be using :pady and :padx rather than :padding. Replacing ':padding "\"1 1\""' with ':padx 1 :pady 1' in able::create-widgets allows able to run. Matt

[Able-devel] Feature request - go back in jump history
by Grz 09 Feb '10

Hi, it's very helpful that you can jump to definition, but it would be even better if you could also go back in jump history. It would make browsing through code so much easier, any chance of implementing that? Rgds, G
