Hello, I don't have a problem running this function. We didn't see all your code, what did you type before and how did you call the function? I don't have a problem when I am in the ltk-user package: (in-package :ltk-user) (defun hello() (with-ltk () (let* ((tx (make-instance 'text ))) (pack tx)))) (hello) => opens a text widget However, to stay in the cl-user package, I prefixed the ltk functions: (defun hello() (ltk:with-ltk () (let* ((tx (make-instance 'ltk:text ))) (ltk:pack tx)))) (hello) => ok So you probably want to "use" ltk, with (use-package :ltk) or in your package definition. Looking at the first steps tutorial (http://www.peter-herth.de/ltk/ltkdoc/node5.html), there is no mentions of packages, but here there is: https://lispcookbook.github.io/cl-cookbook/gui.html#tk Best, Vincent On 28/10/2020 13:00, ltk-user-request(a)common-lisp.net wrote: > Send ltk-user mailing list submissions to > ltk-user(a)common-lisp.net > > To subscribe or unsubscribe via the World Wide Web, visit > https://mailman.common-lisp.net/listinfo/ltk-user > or, via email, send a message with subject or body 'help' to > ltk-user-request(a)common-lisp.net > > You can reach the person managing the list at > ltk-user-owner(a)common-lisp.net > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of ltk-user digest..." > > > Today's Topics: > > 1. error on first steps with LTK (Ulrich Vollert) > > > ---------------------------------------------------------------------- > > Message: 1 > Date: Mon, 26 Oct 2020 19:11:02 +0100 > From: Ulrich Vollert <ulrivo(a)gmx.de> > To: ltk-user(a)common-lisp.net > Subject: error on first steps with LTK > Message-ID: <1722B608-9760-415B-B1D5-87B9B0F14A4C(a)gmx.de> > Content-Type: text/plain; charset=us-ascii > > Hello, > > I am trying to make a text widget: > > (defun hello() > (with-ltk () > (let* ((tx (make-instance 'text ))) > (pack tx)))) > > > But I get an error (here the messages by slime): > > too many colons in "07" > > Stream: #<TWO-WAY-STREAM > :INPUT-STREAM #<SB-SYS:FD-STREAM for "descriptor 16" {1005CE4193}> > :OUTPUT-STREAM #<SB-SYS:FD-STREAM for "descriptor 9" {1005CE45B3}>> > [Condition of type SB-INT:SIMPLE-READER-ERROR] > > Restarts: > 0: [SEND-TO-DEBUGGER] Send condition to the debugger > 1: [ABORT] Abort handling Tk event > 2: [EXIT] Exit Ltk main loop > 3: [RETRY] Retry SLIME REPL evaluation request. > 4: [*ABORT] Return to SLIME's top level. > 5: [ABORT] abort thread (#<THREAD "repl-thread" RUNNING {10026087A3}>) > > Backtrace: > 0: (SB-IMPL::READ-TOKEN #<TWO-WAY-STREAM :INPUT-STREAM #<SB-SYS:FD-STREAM for "descriptor 16" {1005CE4193}> :OUTPUT-STREAM #<SB-SYS:FD-STREAM for "descriptor 9" {1005CE45B3}>> #\1) > 1: (SB-IMPL::READ-MAYBE-NOTHING #<TWO-WAY-STREAM :INPUT-STREAM #<SB-SYS:FD-STREAM for "descriptor 16" {1005CE4193}> :OUTPUT-STREAM #<SB-SYS:FD-STREAM for "descriptor 9" {1005CE45B3}>> #\1) > 2: (SB-IMPL::%READ-PRESERVING-WHITESPACE #<TWO-WAY-STREAM :INPUT-STREAM #<SB-SYS:FD-STREAM for "descriptor 16" {1005CE4193}> :OUTPUT-STREAM #<SB-SYS:FD-STREAM for "descriptor 9" {1005CE45B3}>> NIL NIL T) > 3: (SB-IMPL::%READ-PRESERVING-WHITESPACE #<TWO-WAY-STREAM :INPUT-STREAM #<SB-SYS:FD-STREAM for "descriptor 16" {1005CE4193}> :OUTPUT-STREAM #<SB-SYS:FD-STREAM for "descriptor 9" {1005CE45B3}>> NIL NIL NI.. > 4: (READ-EVENT :BLOCKING T :NO-EVENT-VALUE (NIL)) > 5: ((LABELS LTK::PROC-EVENT :IN LTK::MAIN-ITERATION)) > 6: (MAINLOOP :SERVE-EVENT NIL) > 7: ((LAMBDA (CONDITION) :IN LTK::MAKE-CONDITION-HANDLER-FUNCTION) #<SIMPLE-ERROR "When reading from tcl, expected a list but instead got ~S" {1005CFB063}>) > 8: (SB-KERNEL::%SIGNAL #<SIMPLE-ERROR "When reading from tcl, expected a list but instead got ~S" {1005CFB063}>) > 9: (ERROR "When reading from tcl, expected a list but instead got ~S" |2020-10-26|) > 10: (LTK::VERIFY-EVENT |2020-10-26|) > 11: ((LABELS LTK::PROC-EVENT :IN LTK::MAIN-ITERATION)) > 12: (LTK::MAIN-ITERATION :BLOCKING T :REENTRANT?

The error is caused by a message from wish in reply to the creation of a text widget. The message is described here http://74.208.161.176/tk/tktview/855049e799 <http://74.208.161.176/tk/tktview/855049e799> I reinstalled TCL/TK to Tcl 9.0a2 & Tk 9.0a2 (on macOS Catalina 10.15.6), and the message is gone, so is my error ;-) Regards, Ulrich
