Loading McCLIM examples fails with type error on ECL under Linux

When I use Quicklisp to load the McCLIM examples from ECL I get a type error (but loading just McCLIM completes with no issues): paolo@lispmachine:~$ ecl ;;; Loading #P"/home/paolo/quicklisp/setup.lisp" ;;; Loading #P"/home/paolo/apps/ecl/lib/ecl-26.5.5/asdf.fas" ECL (Embeddable Common-Lisp) 26.5.5 (git:UNKNOWN) Copyright (C) 1984 Taiichi Yuasa and Masami Hagiya Copyright (C) 1993 Giuseppe Attardi Copyright (C) 2013 Juan J.

Help with implementing Cocoa backend (1. scroll pane coordinates/size; 2. menu bar implementation)
by 凉凉 23 Mar '26

23 Mar '26

The backend implementation source code could be found at: https://codeberg.org/li-yiyang/McCLIM/src/branch/backend-coca (backend-coca branch, under Backends/coca) The current screenshot could be see at: https://mastodon.social/@lucky_magick/116279407124461376 1. Issue: the scrolling part effective height is not stretched down correctly 2. Need Advice: how to suppress the menu-bar to use native menu-bar? I read on the manual that it's possible. It's sad that currently if triggering menu-bar would pop drop down menu in another window, which would cause current backend crash. Dev Note: The McCLIM-Coca should be able to load like: git clone --branch backend-coca https://codeberg.org/li-yiyang/McCLIM.git ;; due to Cocoa limits, GUI thread (NSApp run) will replace the main thread sbcl --eval "(ql:quickload '(:clim-listener :mcclim-coca))" \ --eval "(bt:make-thread (lambda () (setf clim:*default-server-path* :coca) (clim-listener:run-listener)))" ;; ECL could also load, but breaks down frequently Why not old beagle backend: I wrote a little ObjC bridge to replace CCL's objc bridge. (Backends/coca/objc) The API (lockFocus) is outdated and cannot work on my computer. So I use CGBitmapContext to replace. I don't have much ObjC Cocoa programming experience so not sure if the ObjC code is correct. I have to ask AI to generate ObjC code and rewrite their logic into lisp code. (Hopefully this would be blamed) Thanks for your time reading this. 凉凉, Yiyang Li, thebigbigwordl(a)qq.com

[rfc] manual changes
by Daniel Kochmański 14 Feb '26

14 Feb '26

Dear All, I've recently started working a bit on improving McCLIM manual and wrote initial versions of two sections: Development history old: https://mcclim.common-lisp.dev/static/documents/d35e5b1-mcclim-doc-current.… new: https://mcclim.common-lisp.dev/static/documents/3d6249-mcclim-doc-sketch.ht… Time between 2002 and 2016 is based on git history and very helpful comments from Christophe Rhodes and Gilbert Baumann. It is a draft and I'm writing here to ask old timers to comment on adequacy from the historical perspective (if anyone can recall) and whether people are correctly attributed. I did my best to balance contribution importance based on little info I had. I've also rebalanced a bit years 2000-2002 to focus less on Gsharp (but still preserve all attributions) and more on the codebase merge and presentation system development. As much as I'd like to, it is hard to be objective about recent years 2016-2026 given my constant involvement, so if you have a different perspective then please offer corrections. Please write on the mailing list what do you think of it and suggest further improvements if there are any. Getting Started old: https://mcclim.common-lisp.dev/static/documents/d35e5b1-mcclim-doc-current.… new: https://mcclim.common-lisp.dev/static/documents/3d6249-mcclim-doc-sketch.ht… I've also written an new Getting Started section. Instead of a few disconnected toy applications I've tried to describe one that covers clim-specific basics - frames, presentation types, commands and translators. Gathering feedback on this is also important to me.

I've developed a file selector dialog for McCLIM. It's in Quicklisp as "select-file". (It also works in Franz Allegro CLIM since my application is multi-platform). Unfortunately, it's a little out of date now since (for various boring reasons) I'm still on McCLIM of March 2024. Also, it's not a gadget as such but an implementation of the function select-file in the Franz Inc CLIM 2 User Guide section 19.4 – with a much more attractive and usable interface than the Franz version. Here's a screenshot so you can see what it looks like and get an idea of how to interact with it: https://users.sussex.ac.uk/~johnca/selectfile.png Perhaps some of the code could be repurposed to make a gadget.

rubber band tracking-pointer drawing failing to appear?
by John Morrison 26 Dec '25

26 Dec '25

Hi; Seasons Greetings! In my CLIM app, the tracking-pointer-drawn box in my "rubber band zoom" has ceased to appear (mind you, I did break lots of things during a refactor). I am unsure exactly when (with respect to McCLIM or OS updates) when it stopped working. n my attempt to resurrect it, I tried the example from here <https://www.lispworks.com/documentation/lw81/clim/clim-ch15-5.htm>. I couldn't get it to work either. Please find attached a hopefully self-contained update of that example which demonstrates the failure mode under: - Linux Fedora Core 42 - kwayland-6.5.4-1.fc42.x86_64 - xorg-x11-server-Xwayland-24.1.9-1.fc42.x86_64 Sorry in advance if this turns out to be Pilot Error. If so, I will take my well-deserved lumps in public. -jm --- John Morrison <jm(a)symbolic-simulation.com> Chief Technology Officer Symbolic Simulation, LLC <https://www.symbolic-simulation.com> m: (617) 388-3071 <+1-617-388-3071> <https://www.symbolic-simulation.com> *CONFIDENTIALITY NOTICE: The information transmitted by this email is intended only for the person or entity to which it is addressed.

busy cursor
by John Morrison 11 Oct '25

11 Oct '25

Hi; Sorry if this is either a dumb question or Pilot Error, but I am having trouble showing the user a "busy" cursor when a long-running command is invoked. - Current "master" codeberg McCLIM - Fedora Core 41 - xorg-x11-server-Xwayland-24.1.8-1.fc41.x86_64 - SBCL vintage 2.1.1 (homebuilt) I *THINK* I used to be able to do this years ago running under X11 (vs Wayland). Please find attached a hopefully short program which either shows the problem, or shows my ignorance. Thanks in advance for any help. -jm --- John Morrison <jm(a)symbolic-simulation.com> Chief Technology Officer Symbolic Simulation, LLC <https://www.symbolic-simulation.com> m: (617) 388-3071 <+1-617-388-3071> <https://www.symbolic-simulation.com> *CONFIDENTIALITY NOTICE: The information transmitted by this email is intended only for the person or entity to which it is addressed.

Hello Johan, On Saturday, May 3rd, 2025 at 7:26 PM, Johan Kumlien <johanrgkumlien(a)gmail.com> wrote: > Unfortunately the latest McClim craches when loading on my new Apple M3 Ultra using quicklisp and SBCL. > Is this a known problem? - I haven't seen anything about it on the net. > Is there a way around it? > Is someone working on it? > > Thank you in advance for information/help > Johan Kumlien I'm not aware of this problem. Could you provide more information about the crash? 1. console log 2. backtrace (if it lands in a debugger) 3. sbcl version 4. last version that worked for you on this computer Moreover you may try using McCLIM directly from the repository. The latest Quicklisp lags a few months behind our latest release. I don't think that this will help with the crash though. Also please note that a preferred way to report issues is on the tracker located here: https://codeberg.org/issues Best regards, Daniel
