|3b|: the defparameter would basically perform a setf if it already exists, so affecting the current binding makes sense
0:21:14
|3b|
if it did setf of symbol-value it would affect the global binding, setf of name directly would be local, i guessed global since i think of it in terms of global variables, but spec says name

the biggest problem with trying to read backwards is the stupid CRLF that some files use
0:35:13
White_Flame
if you can guarantee a LF character, then you could scan backwards for X number of those
0:36:20
White_Flame
if you're sorting strings, then it's up to you to do the zero padding or conversion to numbers
0:37:20
White_Flame
but if you're not sorting it yourself, then you cannot rely on the ordering of files being consistent

What's the best library for storing simple lisp objects, no functions or clos, into files?

printers of FP numbers have generated ascii representations that can be read back in bit-for-bit matching for decades now
0:51:07
|3b|
just make sure you include type in the ascii (1f0 or 1d0 instead of 1.0 etc) or READ with same default float format
0:55:01
|3b|
might also look at WITH-STANDARD-IO-SYNTAX when using write/read for data files, so you can try to have a consistent state more easily

beach oh you know, very slowly :-) working on the best way to support multiple values currently

If one applies CL:REVERSE to a vector specialized on a given type (unsigned-byte 32), is a conforming implementation allowed to return an unspecialized result?
6:50:21
easye
From <http://www.lispworks.com/documentation/HyperSpec/Body/f_revers.htm>, a conforming implementation has to have an "actual array element type" so I'm judging the answer to be yes.
6:53:36
phoe
so, "For reverse, if sequence is a vector, the result is a fresh simple array of rank one that has the same actual array element type as sequence."
6:54:10
phoe
"For reverse, if sequence is a vector, the result is a fresh simple array of rank one that has the same type for which the array is actually specialized as the input sequence."
6:54:25
phoe
so I read it as: if you pass a specialized vector of ub32, then the result must also be a specialized vector of ub32
7:05:19
phoe
if your answer is "yes, the implementation is allowed to return an unspecialized result" then I guess I disagree
7:05:54
easye
No, I agree that having CL:REVERSE return an unspecialized type for a specialized argument would be non-conforming.

ok is there a way to maybe swop out two methods and runtime and then swop them back with the mop?
9:03:29
beach
Heh, you need the "Incless" library that is not finished yet, but that would allow you to play tricks like that.
9:12:37
Harag
is incless taking over printing "control" using shadowing and then giving its own implementation?
9:24:25
beach
So the print-object methods trampoline to a generic function print-object-using-client.
9:25:18
beach
So you would put a method on print-object-using-client with a client that alters the printing as you want.
9:25:52
beach
Then when you want the altered behavior, you bind INCLESS:*CLIENT* to the one that behaves like that.
9:27:02
beach
I think we (collectively) are getting the hang of creating implementation-independent libraries. :)
9:31:38
phoe
you don't need to make a fancy name for first-class global environment because "class" already contains the "cl" substring that is required

beach: no. My wife is a nurse, and daughter is becoming one, so I'm hearing stuff like that a lot.

if there is a problem with dynamic bindings please report a bug. unless you mean, that ecl inlines some functions?
10:34:01
phoe
if you are trying to FLET/LABELS/MACROLET any function or macro or special operator from the CL package, it's undefined behavior

random note: today, I have removed the last TODO from my upcoming condition system book
10:55:38
phoe
but it seems like after my editors have a go at the last bits of text I've introduced, it is ready to go into production
10:58:14
phoe
I think that most of the heavy lifting has been done by the Lisp community though; digikar and gendl and heisig and adlai and splittist and SAL9000 and *way* *WAY* too many people to count here have done a #.most-positive-fixnum amount of work with beating my words into proper shape
10:58:53
phoe
to the point where the editor from Apress didn't really have anything to do, save for restructuring the chapters in the way that is acceptable by Apress and noticing like two or three minor issues that weren't caught earlier
10:59:09
SAL9000
(I really should get around to putting a reviewer blurb thing into that issue before it's too late)
11:02:46
heisig
phoe: Congratulations on removing your last TODO! I am very excited about this book.
11:03:27
heisig
I secretly hope that other language designers will read it and adapt their languages accordingly :)
11:03:34
phoe
like, literally, the Hall of Fame section of my book is so fat that I am grinning just looking at it

" is a fine verb though. phoe, do not be concerned if you find it (in the verb position)
