Hi Juanjo,Chinese words work in windows console now！

Hi Juanjo，I update to new version Ecl. The Chinese words work in windows console now. Thank for your help.
But if I write the code into a lisp file and use load command in repl. it report error:

> (load "code/hello.lisp")
;;; Loading "D:/ecl/code/hello.lisp"

Condition of type: STREAM-DECODING-ERROR
decoding error on stream #<input stream #P"D:/ecl/code/hello.lisp"> (:EXTERNAL-F
ORMAT (:UTF-8 :LF)): the octet sequence (255) cannot be decoded.
Available restarts:

1. (CONTINUE) Read next character
2. (USE-VALUE) Replace the bogus sequence with a character
3. (RESTART-TOPLEVEL) Go back to Top-Level REPL.

Broken at SI:BYTECODES. [Evaluation of: (LOAD "code/hello.lisp")] In: #<process
TOP-LEVEL>.

I export the file as utf-8 or utf-16, it's all failed.

C.M.

how to get the line number of code from error message!

I write a hello.lisp file like this:
(print "hi")
(length '(a . b 1))

and I load it in to ecl:
> (load "code/hello.lisp")

;;; Loading "D:/ECL/code/hello.lisp"

"hi"
Condition of type: SIMPLE-READER-ERROR
Reader error in file #<input stream #P"D:/ECL/code/hello.lisp">, position 30:
Too many objects after a list dot

Available restarts:

1. (RESTART-TOPLEVEL) Go back to Top-Level REPL.

Broken at SI:BYTECODES. [Evaluation of: (LOAD "code/hello.lisp")] In: #<process

It has not line number in error message but postion 30.
I found it is the position of characters. how to get the line number of code from error message?

Thank for your help!

Codepage problems in Windows' console

Hi everybody,

after spending two days reading stuff about documented and undocumented functionality in Microsoft's API and CRT, I have come to the following conclusions:

* In Windows, it is impossible to reasonably use POSIX functions to read/write text from the console without letting the console do some translation for you.

* Moreover, POSIX's functions do not work, because read() and write() may actually read or write more bytes from the buffer thant you would want, precisely due to this "clever" translation.

* This all renders the CRT unusable, and as stated in a MSDN blog from Windows, one should stick to the Console read and write operations and forget about C entirely.

Well, I have coded a prototype of a Lisp stream for the console. ECL now has code that will detect whether the input/output/error channels are consoles and wrap them around with these streams. Moreover, it will also detect the current codepage and use it as external format for the stream.

All this is pretty much experimental and I need your help testing it. Please report problems.

BTW, as usual, all this is only available in git/CVS

Need help testing this...

ECL now implements asynchronous signal handlers through a secondary thread and these handlers can now be customized. The interface is given by the functions

(EXT:GET-SIGNAL-HANDLER signal-code)

(EXT:SET-SIGNAL-HANDLER signal-code closure-or-symbol)

where the signal handler function should have the signature (LAMBDA (&KEY PROCESS)).

On a multithreaded ECL, instead of having a thread that relies on sigwait(), we have a thread that gets messages from other threads, which are the ones that received the signals. In principle we could optionally add a feature such that these threads get suspended until the signal is processed. This does not seem critical to me, but it might help cope with the problem of synchronous signals (SIGSEGV, SIGFPE, etc) which are not allowed to execute arbitrary code.

In any case, these are refinements for the future. I would like to ask you to help debugging and perfect the changes I just introduced, and which for me are the final milestone for a release (apart from testing and integrating the ASDF extensions).

Decent HTTPd uptime since recent threading/locking changes

I had to reboot the system for another reason, but before I did, I
checked the uptime of my HTTPd and it was up online during 30 days.
Most of the connections were from google and vulnerability probing
spiders, although interspersed with my Apache ab(8) test floods.  This
was still using a non-shrinking threads pool for now.  Awesome :)

Slime lambda-list auto-help

Hello again,

Although it's a minor issue, I noticed lately that when entering Lisp
the following form using latest ECL (head) and latest Slime, I'm
getting the following error in the command buffer:

(with-open-file 

    error in process filter: Wrong number of arguments: nil, 137

I'm not sure if the problem is in Slime or in ECL.

Also, is it expected that this help only is available for
implementation functions and bytecode compiled custom fonctions?  I
built my code with the debug level 3, but I cannot get that automatic
interactive help for the functions of those files.

Example:

(defun foo (a b c)
  (list a b c))

(foo<space>[I get the lambda-list help here]

(compile 'foo)

(foo<space>[I no longer get it]

Thanks,
--

Re: [Ecls-cvs] compiling to a standalone exe win7 visual studio 2010 (SOLVED)

Thank you! Once I did this one other thing came up so I'll just document the short process here for future travelers:

> (require :cmp)

> (setf C::*COMPILE-IN-CONSTANTS* t)

> (compile-file "hello.lisp" :system-p t)

> (c:build-program "myecl" :lisp-files '("hello.obj"))

The resulting exe was 7.16 kB, very nice!

You are using the bytecodes compiler -- it is active by default in Windows because there are normally no compilers around. Use (require :cmp) before the process.

I noticed at the point where I compile, I see #P"hello.fasc" while the webpage says #P"hello.o".

Also I don't see any mention of 'invoking the compiler'.

I looked through the makefile and didn't see any switches.

Is there something easy I'm missing? Thank you!
