Is there a way to get the kind list of a condition without converting
the whole condition into a list?
This example:
(let* ((fail (lambda () (open-input-file )))
(exn (call/cc (lambda (return)
(with-exception-handler return fail)
(map car (condition-list
The attached patch adds a syslog-str function to the syslog egg. The
function does not use sprintf. It requires an already formated string.
This is useful if one wants to use the fmt egg to format syslog
messages.

I think there seems to be a string protection error in the syslog egg.
The C function openlog requires a const string and relies on the fact
that the string does not change. Normally Scheme strings are moved
around by the garbage collector. This is a problem for openlog. The
result are random
The code of the syslog egg uses
syslog(prio,\%s\,msg);
to send the message. On Linux the above code is about 30% slower than this:
syslog(prio, msg);
Some time ago I did a performance test:

And on Linux
It is possible to avoid the ident parameter:
(program-name people-bridge)
(openlog #f opt/pid facility/local0)
But setting the program name does not have any effect on the generated
syslog message:

It does not have any effect on the

Try this instead:
csi -R sxpath-lolevel -e (print (sxml:sxml-xml '()))
Thanks. This works but not as expected ;-)
I was looking for the srl:sxml-xml function:

Is it also available?

Actually, the main reason is that SSAX is a horrible mess which has
many completely unrelated procedures all mixed together.
There are several egg that provide different sets of procedures
from the SSAX project. Most eggs include all files from the

Other ways were to regularize and improve some of the identifier names, make
things more idiomatic, and in sxml-serializer's case, add some feature
enhancements.
Where is the improvement? Writing sxml-serializer instead of

As a quick fix you can adjust the sendfile.setup to include the features
that are present.
Something like:
(compile -s -O2 -d0 -D sendfile -D mmap -D madvise sendfile.scm -j sendfile)
instead of:

- due to a limitation in abnf/lexgen-derived parsers, #f cannot be a

Can you explain this? I tried my patch with some booleans and it seems to
I am a bit confused by the way the JSON egg maps JSON structures to
Scheme values. The JSON egg maps a structure to a vector:
(use json)
(with-input-from-string {\pi\:3.14,\e\:2.71} json-read)
;; = #((pi . 3.14) (e . 2.71))
This makes it impossible to use the standard Scheme function assoc to

My guess is that it makes it possible to write back to json, since
alists are already used for representing a different datatype.
But json-write does not accept alists as values. This

You may be interested in two alternative JSON eggs, namely json-abnf egg

The json-abnf module creates some strange results for booleans:

(pp (parser {\str\:\a\,\true\:true,\false\:false}))
prints:

true is a list and false is '().
