Reloading slime.el upon starting SLIME.
by Dmitry Igrishin 14 Dec '15

14 Dec '15

Hello, Recently after switching branches in my SLIME Git repo I caught a message about slime/swank versions inconsistence. Presently SLIME urges to recompile slime.el if slime.elc is found and it older the slime.el, but it does not reloads slime.el automatically if it has been changed. The first solution which comes to the mind is the store md5 hashsum of the current slime.el and check it every time of SLIME loading. Thoughts?

macroexpansion (slime-expand-1) results in error
by Mirko Vukovic 13 Dec '15

C-c Ret returns an error on some macros (but not on others): The value NIL is not of the expected type ARRAY. [Condition of type TYPE-ERROR] Restarts: 0: [*ABORT] Return to SLIME's top level. 1: [ABORT-BREAK] Reset this thread 2: [ABORT] Kill this thread Backtrace: 0: (CCL::ARRAY-DATA-AND-OFFSET NIL) 1: (MAKE-STRING-INPUT-STREAM NIL 0 0) 2: (READ-FROM-STRING NIL T NIL :START 0 :END NIL :PRESERVE-WHITESPACE NIL) 3: ((:INTERNAL SWANK::FROM-STRING)) As stated above on other macros it works fine. This is on latest CCL release on 64-bit Windows 7, slime 2015-10-18. I don't know how to generate more debugging information. Any thoughts? Thanks, Mirko

Slime startup sometimes: Undefined function SWANK::SYMBOL-INDENTATION
by Mark H. David 12 Dec '15

I frequently see this (see debugger backtrace below) when starting SLIME. Not all the time. I suspect it's a timing issue. Anyone see this? Anyone looked into fixing? Thanks, --Mark Undefined function SWANK::SYMBOL-INDENTATION called with arguments (:BREAK-OPTIONS-STRING) . [Condition of type CCL::UNDEFINED-FUNCTION-CALL] Restarts: 0: [CONTINUE] Retry applying SWANK::SYMBOL-INDENTATION to (:BREAK-OPTIONS-STRING). 1: [USE-VALUE] Apply specified function to (:BREAK-OPTIONS-STRING) this time. 2: [STORE-VALUE] Specify a function to use as the definition of SWANK::SYMBOL-INDENTATION. 3: [ABORT-BREAK] Reset this thread 4: [ABORT] Kill this thread Backtrace: 0: ((:INTERNAL SWANK::CONSIDER SWANK::UPDATE-INDENTATION/DELTA-FOR-EMACS) :BREAK-OPTIONS-STRING) 1: (#<Anonymous Function #x302000BD1E4F> :BREAK-OPTIONS-STRING) 2: (CCL::APPLY-TO-HTAB-SYMS #<COMPILED-LEXICAL-CLOSURE #x2389553F> #(:NFRAMES #<Unbound> :CODE 0 :PAUSE-PERIOD 0 ...)) 3: (CCL::ITERATE-OVER-PRESENT-SYMBOLS #<Package "KEYWORD"> #<COMPILED-LEXICAL-CLOSURE #x2389553F>) 4: (CCL::ITERATE-OVER-ALL-SYMBOLS #<COMPILED-LEXICAL-CLOSURE #x2389553F>) 5: (SWANK::UPDATE-INDENTATION/DELTA-FOR-EMACS #<HASH-TABLE :TEST EQ size 228/305 #x302000AC574D> (#<Package "X86-DARWIN64"> #<Package "X8664"> #<Package "KEYWORD"> #<Package "CCL"> ..) #<Package "COMMON-.. 6: (SWANK::PERFORM-INDENTATION-UPDATE #<MULTITHREADED-CONNECTION #x302000AC56AD> (#<Package "X86-DARWIN64"> #<Package "X8664"> #<Package "KEYWORD"> #<Package "CCL"> #<Package "COMMON-LISP"> ..) #<Package.. 7: ((:INTERNAL SWANK::INDENTATION-CACHE-LOOP)) 8: (SWANK/BACKEND:CALL-WITH-DEBUGGER-HOOK #<Compiled-function SWANK:SWANK-DEBUGGER-HOOK #x302000A414FF> #<COMPILED-LEXICAL-CLOSURE (:INTERNAL SWANK::INDENTATION-CACHE-LOOP) #x302000ACFD1F>) 9: (SWANK::INDENTATION-CACHE-LOOP #<MULTITHREADED-CONNECTION #x302000AC56AD>) 10: (CCL::RUN-PROCESS-INITIAL-FORM #<PROCESS swank-indentation-cache-thread(6) [Active] #x302000AC982D> (#<COMPILED-LEXICAL-CLOSURE (:INTERNAL CCL::%PROCESS-RUN-FUNCTION) #x302000AC95BF>)) 11: ((:INTERNAL (CCL::%PROCESS-PRESET-INTERNAL (PROCESS))) #<PROCESS swank-indentation-cache-thread(6) [Active] #x302000AC982D> (#<COMPILED-LEXICAL-CLOSURE (:INTERNAL ..))) 12: ((:INTERNAL CCL::THREAD-MAKE-STARTUP-FUNCTION))

help writing a contrib
by Jim Newton 03 Dec '15

03 Dec '15

I hope someone can help me with a few things I'm confused on. I've trying to write a slime contrib (for the first time). I have already written the common-lisp function which works fine. But I want to write the elisp front-end to this function. The elisp function should get the symbol at the point create a temporary file name, then it should call the common lisp function passing those two arguments. After the CL function returns, emacs should open the file named by the tmp file name. There are several issues I'm not sure how to answer. 1. the symbol at the point has an implicit package name, I want the CL function to receive the correct symbol. E.g. suppose the symbol is xyzzy which is CL parses as abc::xyzzy (because if an in-package earlier in the file), I want the CL function called with 'abc::xyzzy not with 'CL::xyzzy. 2. If I try to call the CL function using slime-eval with a string, then CL understand the correct symbol, but slime-eval returns t before the CL function returns, and when I call find-file, the file is not ready to open yet. 3. If I try to call the CL function with slime-eval-async, then the CL function receives the wrong symbol: CL::xyzzy rather than abc::xyzzy. 4. I would like to put the .lisp file also in the contrib directory, but the CL code depends on c2mop. Does this pose a problem? What do I need to assure that if a user loads the file that c2mop has already been loaded? I.e., is there an asd file I need to create or modify? If someone could point me in the right direction, it would be great. BTW here is the elisp function as I currently have it. (defun class-graph (class-name) (interactive "P") (let* ((class-name (or class-name (slime-symbol-at-point))) (tmp-file (make-temp-file (format "%s-" class-name) nil ".png"))) (cond ((slime-eval (format "(class-graph:class-graph-for-slime '%s %S)" class-name tmp-file)) ;; this does not work, becasue tmp-file is not ready as class-graph-for-slime has not yet finished. (find-file tmp-file) (image-mode-fit-frame)) (t (error "failed to create graph in %s" tmp-file)))))
