Re: How to get the signature of function and method definitions
Hi Thorsten,
I think this error occurs because the binary 'picolisp' cannot be found.
strange, I changed $PATH and emacs exec-path:
As far as the 'picolisp' executable is concerned, the $PATH doesn't
matter at all. All that counts is how it is invoked by the scripts.
About emacs exec-path, however, I can't say anything.
and still get the same error message:

What happens if you execute it in the shell

I assume that this 'pil' file is
#!/bin/sh
exec ${0%/*}/bin/picolisp ${0%/*}/lib.l @ext.l $@
so you see that it will try to execute
/home/tj1/bin/picolisp/bin/picolisp
What does the command
$ file /home/tj1/bin/picolisp/bin/picolisp
say?
and there is an executable 'picolisp' in /home/tj1/bin/picolisp/bin
(and without slime, with inferior picolisp mode, it works)
Ah, ok, I see.
Hmm, then I'm a bit clueless ...

Hi Thorsten, so thats the solution - I have a local installation, I set the 4 links to /usr/bin/ and /usr/share/ as described in INSTALL - but apparently only /usr/share/picolisp is the one that works. I have no idea why. how did you install your local picolisp? Did you cd src; make? Can you find the bin/picolisp executable file after that? after changing all calls to 'pil' to '/usr/share/picolisp/pil' and the call to swank-picolisp to '/usr/share/picolisp/lib/swank-picolisp' things worked - more or less. The connection to slime worked, I get a slime-repl with a pil prompt, and calculations like (+ 3 4 ) work - but everything is extremely slow, and after each keystroke I get 'wrong number of arguments' errors ... OK. Now how exactly did you set up your slime? I think Henrik had a similar problem because he was using some slime contribs that swank-picolisp doesn't support. If you start with those contribs I sent in the previous email, it should work. The problem you are seeing is that when you move your cursor, emacs talks to picolisp to find information about symbols your cursor points at, e.g. if you write pil (+ 1 2) and then place your cursor above +, slime tries to display information about +. I use emacs autodoc and in this case, I see that the symbol plus is a built-in function, its address and arguments. It is slow for you because something about this autodoc stuff doesn't work for you. but anyway - it works, somehow, finally. I should become a software- and usability-tester, I have what it takes ;) Great;-) You could have a look at the inferior-lisp buffer and you'll see some messages sent forth and back between emacs and picolisp. It should give you an idea what the problem is. Cheers, Tomas -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe

Re: How to get the signature of function and method definitions
Hi Henrik, Thorsten, Because with the help of CTags I can jump to any defined function or method in a .l file. I tried it once to set up TAG files, but I didn't really succeed. I think I have to read a bit more in the Emacs manual and then try your tutorial again. TAGS seem to be really usefull, not only for Picolisp, but everywhere in Emacs. I think that the necessary tags are already there, or can be easily generated. At least in the latest version of PicoLisp (this was extended recently a bit). You can - again - take the 'vi' function as example. It generates a temporary file ~/.pil/tmp/pid/tags upon startup, so that all functions defined in the current session are included. The other symbols (all built-in functions and assembly-level labels, equates etc.) already come with the distribution in src64/tags). So, in 'vi', after you edit a function, e.g. : (vi 'doc) you can move the cursor on other symbols, e.g. 'call' in the next line, and hit Ctrl-']'. There, you may click on 'CDR', and so on. I think it should be easy to adopt this mechanism to other editors. Cheers, - Alex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe

Re: How to get the signature of function and method definitions
1.) Lisp level functions are handled anyway by the jump to documentation script. 2.) It's only a problem when jumping as you then jump to the incorrect file but since I don't do much global functions anyway this is not a problem for me, if I jump to http for instance I end up in the right file. 3.) Correct and could become a potential annoyance when jumping, unfortunately my autocompletion only locks on to the predefined lisp functions and all definitions in all open buffers so there it is not a problem (I was wrong before when I wrote in my article that it would lock on tags too).

Re: How to get the signature of function and method definitions
Hi Thorsten, Thats quite impressive, thanks. I thought slime/swank is only for communication with compiled lisps, but well ... slime/swank is a client/server protocol. There are backends e.g. for Common Lisp, Scheme, Clojure, R, Picolisp and probably more. It is not difficult to write a new backend, if your interpreter supports the features you are after. I find it much better that the traditional commint stuff. I use slime daily and can't imagine life without it anymore;-) Definitely the way to go if you don't follow Alex's steps with xterm and vi. I haven't implemented the whole protocol yet, but the subset in swank-picolisp is already usable and very helpful. I can open a picolisp file in slime-mode now, but I can't connect (with slime-connect): ,--- | Connecting to Swank on port 4005.. [2 times] open-network-stream: make | client process failed: verbindungsaufbau abgelehnt, :name, SLIME | Lisp, :buffer, nil, :host, 127.0.0.1, :service, 4005 `--- I have to check my slime installation ... Is that still valid, or should it rather be 'pil ore 'plmod now? ,--- | (setq slime-lisp-implementations | `((picolisp (/usr/bin/picolisp/p) :init slime-init-picolisp))) `--- Yes, I think the way picolisp is launched has changed recently, so you need the use the correct shell script, likely pil. Please let me know it it worked for you. You should get a repl and then type (+ 1 2) and get the result. If you move your cursor around, you should see function arguments in the message buffer and if you do M-. and M-, then you should be jumping around the sources. So, the connection via swank replaces the connection via inferior-picolisp/commint - or uses it? And slime-mode replaces picolisp-mode, or adds new functionality to it? Swank is a client/server protocol that doesn't use commint mode, it talks to the picolisp interpreter via socket. Slime mode extends picolisp mode with the ability to talk to the server interpreter(s) via the swank protocol. Thats new terrain, I only knew about swank from ENSIME, the emacs scala mode, never used slime/swank with a lisp. I didn't know Scala worked with slime too. I recommend reading about slime and watching some videos (look for slime and Marco Baringer), e.g. http://www.youtube.com/watch?v=_B_4vhsmRRI http://bc.tech.coop/blog/050728.html http://common-lisp.net/project/slime/ https://secure.wikimedia.org/wikipedia/en/wiki/SLIME http://www.emacswiki.org/emacs/SlimeMode Cheers, Tomas -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe

How to get the signature of function and method definitions
Hi list, I remember that Alex recently mentioned a method how to get the signature of any function or method definition loaded in the system. Unfortunately, I could not find the related post again. Any hints where I have to look would be appreciated. cheers -- Thorsten -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
Re: How to get the signature of function and method definitions
I don't know if this is exactly what you want but (all) can be used to inspect stuff, an example of getting all loaded classes: (de getClasses () (filter '((S) (and (= `(char +) (char S)) (type S))) (all))) On Thu, Nov 10, 2011 at 7:27 PM, Thorsten quintf...@googlemail.com wrote: Hi list, I remember that Alex recently mentioned a method how to get the signature of any function or method definition loaded in the system.

Re: How to get the signature of function and method definitions
Hi Thorsten, I remember that Alex recently mentioned a method how to get the signature of any function or method definition loaded in the system. I'm not completely sure what you mean with signature in this context. You can inspect a function by pretty-printing, : (pp 'insert) (de insert (N Lst X) (conc (cut (dec N) 'Lst) (cons X) Lst) ) by looking at it with an editor (sorry, only 'vim' at the moment), : (vi 'insert) or access its reference : (doc 'insert) A signature in the sense of C or Java is perhaps : (car insert) - (N Lst X) i.e. the formal parameters of the function.

You can inspect a function by pretty-printing,
: (pp 'insert)
(de insert (N Lst X)
(conc (cut (dec N) 'Lst) (cons X) Lst) )
too much output in this case
by looking at it with an editor (sorry, only 'vim' at the moment),
: (vi 'insert)
that was another question of mine - what would it take to get a

that opens an emacs window?
or access its reference
: (doc 'insert)
gives me this output - is that intended for vim too? (sorry for the long
lines).

A signature in the sense of C or Java is perhaps
: (car insert)
- (N Lst X)
That probably what I was looking for.
i.e. the formal parameters of the function.
Is there is similar method to get the formal parameters of a method?

Re: How to get the signature of function and method definitions
Hi Thorsten, by looking at it with an editor (sorry, only 'vim' at the moment), : (vi 'insert) that was another question of mine - what would it take to get a , | (emacs 'insert) ` function, and a ,--- | (edit 'insert) `--- that opens an emacs window? Yes, this would be nice to have. I don't know enough about emacs, but it should be surely possible. For the first case, the source of 'vi' (lib/debug.l:162) could be taken as a template. The first expression (when (pair X) (setq C (cdr X) X (car X)) ) occurs in a similar form in most debugging functions, and extracts a possible class from the argument(s), i.e. calling (vi 'msg '+Cls) or (vi '(msg . +Cls)) is the same. Then the file and line number is searched in the '*Dbg' property of that symbol or class: (if C (get C '*Dbg -1 X) (get X '*Dbg 1) ) ) and also maintained in a local static variable *Vi for later (repeated) calls and for 'ld'. Then there is some tags file handling, don't know what makes sense for emacs here. The real call of 'vim' is (call 'vim (pack +set tags= (tmp tags) ,./tags) +set isk=33-34,36-38,42-90,92,94-95,97-125 (pack + (car *Vi)) (path (cdr *Vi)) ) Again, some tags fiddling, and the charset for symbols is set in 'isk'. The most important part is the argument +123 (if the line number in the file is 123) and the file's path name in the last two arguments to 'vim'. 'edit' is far more tricky, because it re-opens itself with additional symbols which were clicked on. Perhaps we should think about it once 'vi' is ported to 'emacs'. : (doc 'insert) gives me this output - is that intended for vim too? (sorry for the long lines). : (doc 'insert) 1,02kbloaded-(208730594... Dunno. This is strange. By default, 'doc' simply calls the 'w3m' browser (if neither a browser is in the environment variable BROWSER, nor one was passed as a second argument to 'doc').

The most important part is the argument +123 (if the line number in the file is 123) and the file's path name in the last two arguments to 'vim'. Ok, let me think about this, when I fully understand the 'vi' function I might be able to produce an 'emacs' function, its a nice exercise. 'edit' is far more tricky, because it re-opens itself with additional symbols which were clicked on. Perhaps we should think about it once 'vi' is ported to 'emacs'. agreed. : (doc 'insert) gives me this output - is that intended for vim too?
