Thanks for the report. I've uploaded a new version which should fix this. I've conditionalized the patches on CMUCL because other Lisps don't seem to need it. I also changed your patches a bit. I'd recommend asking on the CMUCL mailing list if this is considered a bug in their Gray streams implementation. The SBCL I have on my server (0.9.7.1) behaves like all the other implementations. Cheers, Edi.

I don't think you can support FILE-POSITION, at least I'm not aware of a way to do that with Gray streams. However, one could invent an accessor like, say, IN-MEMORY-STREAM-POSITION. But one would need to define the exact semantics of this operator. What would you propose? Cheers, Edi.

[flexi-streams-devel] in-memory streams have no way to set external-format?
by Andreas Fuchs 08 Mar '06

08 Mar '06

Hi all, I would like to teach cl-irc about the goodness of external-formats, and because irc doesn't let users specify which external format to use, I need something as flexible as flexi-streams (-: So, once I've read an irc command (as a "line" of latin-1 characters), I'd like to convert it to text that looks the least insane, which is why my code tries several external-formats in a row and returns as soon as it found one that doesn't throw an error: (defun try-decode-line (line external-formats) (loop for external-format in external-formats for decoded = nil for error = nil do (multiple-value-setq (decoded error) (ignore-errors (flexi-streams:with-input-from-sequence (in line) (setf (flexi-streams:flexi-stream-external-format in) external-format) (read-line in)))) do (format t "~&tried ~s: ~S~% error: ~A~%" external-format decoded error) if decoded do (return decoded))) Try it with: (try-decode-line "foo" '((:UTF-8 :EOL-STYLE :LF) (:LATIN-1 :EOL-STYLE :LF))) (alternatively, (map 'vector #'char-code "foo") and with (list (make-external-format...)) calls) And for each of the external formats, I get: There is no applicable method for the generic function #<STANDARD-GENERIC-FUNCTION (SETF FLEXI-STREAMS:FLEXI-STREAM-EXTERNAL-FORMAT) (2)> when called with arguments ((:UTF-8 :EOL-STYLE :LF) #<FLEXI-STREAMS::VECTOR-INPUT-STREAM {ABEFA91}>). Hrmpf! Am I abusing flexi-streams too much or is that a bug? How should one read externally-formatted data from an in-memory stream, anyway? And are string-backed in-memory streams even allowed? How to specify the internal external format for them? (-: Thanks for your time and for developing flexi-streams. In return, I hope to be able to buy you a beverage of your choice in Hamburg (-: Cheers, -- Andreas Fuchs, (http://|im:asf@|mailto:asf@)boinkor.net, antifuchs

[flexi-streams-devel] patch: FLEXI-OUTPUT-STREAM superclasses
by James Bielman 25 Jan '06

25 Jan '06

Hi, I need to replace a horrible mess of character stream vs binary stream code at work and flexi-streams looks like it will help clean all this up nicely. LispWorks (4.3.7 on Linux) was complaining about flexi-output-streams not being output-streams because the superclasses are incorrect---here's a patch: Thanks, James
