Printing a custom representation of hash table at the repl
by Diogo Franco 08 Jul '16

08 Jul '16

Hello, ecl does not specialize the print-object method on hash-tables: > (find-method #'print-object '() '(hash-table t)) > Debugger received error of type: SIMPLE-ERROR > There is no method on the generic function PRINT-OBJECT that agrees on > qualifiers NIL and specializers (HASH-TABLE T) After reading the hyperspec carefully, I think this is ok, it only requires it on standard-object and structure-object. However, i still thought that specializing on hash-table would work, but it doesn't: >> (defmethod print-object ((obj hash-table) stream) (princ "its working" > stream)) > #<standard-method PRINT-OBJECT (#<The BUILT-IN-CLASS HASH-TABLE> #<The > BUILT-IN-CLASS T>)> > >> (make-hash-table) > #<hash-table 000000000493ee40> Shouldn't we still dispatch the call to this method? And if not, what's the best way in ecl to customize the printable representation of a hash-table? I've tried: > > (set-pprint-dispatch 'hash-table (lambda (s obj) (princ "its working" > s))) > NIL > > (make-hash-table) > its working But this sometimes gives an error: > Debugger received error of type: SIMPLE-ERROR > Tried to modified a read-only pprint dispatch table: > #<pprint-dispatch-table 0000000003375210> > Error flushed. Thanks!

I did it right before loading the .fasb file. In my case, i'm building a monolithic fasl with all the dependencies in it, is this your use case as well?

Hello Alexander, Take a look at this issue: https://gitlab.com/embeddable-common-lisp/ecl/issues/216 Daniel's suggestion of requiring :sb-bsd-sockets worked for me. I think this an ecl specific version of sb-bsd-sockets that works.

Using Hunchentoot from a binary, compiled with ECL
by Alexander Artemenko 05 Jul '16

05 Jul '16

Hello, everybody! I continue to test ECL and wanted to create a small webservice, compiled into a binary. But I discovered, that my binary fails with this error: Condition of type: SIMPLE-ERROR Package ((SB-BSD-SOCKETS . #<SB-BSD-SOCKETS package>)) referenced in compiled file NIL but has not been created Available restarts: 1. (IGNORE) Ignore the error, and try the operation again This error is similar to cffi and uiop problem, I wrote recently ( https://mailman.common-lisp.net/pipermail/ecl-devel/2016-June/011119.html). But a trick with making package immutable, like this (asdf:register-immutable-system "SB-BSD-SOCKETS") does not work now. Tested on Ubuntu ECL 16.1.4 and OSX 16.1.2. Full example is available in https://github.com/svetlyak40wt/test-ecl in branch try-web-app. To build a binary, you need to issue ./bootstrap && ./build commands, and after them, run ./test-ecl. Why do I have this problem and how to fix it? -- Alexander Artemenko (a.k.a. Svetlyak 40wt) Blog: http://dev.svetlyak.ru Photos: http://svetlyak.ru Jabber: svetlyak.40wt(a)gmail.com
