Specifying external-format on ECL

Question

How can I specify external-format (for example (:crlf :|cp932|)) on ECL?

I want to write string to file with some encoding. So I type in my REPL like this:

(with-open-file (out "test.txt"
                 :direction :output
                 :external-format '(:crlf :|cp932|))
  (write-string "some string" out))

Then invoked debugger and it show this:

The function EXT:MAKE-ENCODING is undefined.
   [Condition of type UNDEFINED-FUNCTION]

This is an wrong way...? When the external-format is :utf-8, successfully written...

ECL version -- 15.3.7
OS -- Ubuntu 14.04

Based on §19.1.3. External formats in the manual, it looks like the appropriate symbol is actually named "CP819" and is in the package named by "EXT", so you'd use ext:cp819, not :|cp819|. You'd be able to use (:crlf ext:cp819), e.g.:

(with-open-file (out "test.txt"
                 :direction :output
                 :external-format '(:crlf ext:cp932))
  (write-string "some string" out))

Thanks for answering. I'm sorry. Frankly, I read the manual and tried to use `(:crlf ext:cp932)`, but ECL returns `SIMPLE-ERROR` with a message `Cannot find the external symbol CP932 in #<"EXT" package>.` The reason why I use `:|cp932|` is, it is included in the return value of a function `ext:all-encodings`... – t-sin Apr 16 '15 at 15:49
@t-sin Hmm, I'm not an ECL user myself, so I didn't have a way to test this. This answer probably has the the same issue, then? Any chance that `ext:|cp932|` (so lowercase, but in the package) is there? Or `ext::cp932`? Etc? At any rate, this seems to be a discrepancy between the manual and the implementation, so you should probably get on the ECL mailing list/bug tracker/etc. – Joshua Taylor Apr 16 '15 at 16:05
@joshua-taylor thanks for advising! Umm, it's means, perhaps, my ECL building way is wrong... I'll ask it in ECL community. – t-sin Apr 20 '15 at 16:06
@t-sin BRPocock said that using `ext::cp932` worked; did it work for you? – Joshua Taylor Apr 20 '15 at 16:39
@joshua-taylor Sorry, I forgot to write... It did not work in my machine. My environment is not enough to build ECL maybe... – t-sin Apr 21 '15 at 05:22

Please fallback to ECL 15.2.21 or use git head - this is a bug introduced in 15.3.7
