[fset-devel] Patch to the .asd file
by Faré 04 Jan '13

04 Jan '13

I sent this patch to Scott and the asdf-devel mailing-list earlier, with no reply. Hopefully, it's just Scott taking deserved vacations from coding. Anyway, just for the record, I'm sending it here, too. It removes some obvious bogosity with the .asd file that was never supposed to work and that definitely breaks the latest ASDF. The thing that DOES work is the :depends-on statement, which is correct. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org Politicians are like rats.

[fset-devel] Fix for SBCL 1.0.53
by Nikodemus Siivola 10 Nov '11

10 Nov '11

As of recently SBCL's fixnums are 63 bits long on 64-bit platforms -- which breaks FSET. Sticking the following definitions into port.lisp in place of the current ones should make things better. ...but I didn't actually verify that the rest of FSET works sanely with these values. (I'm not on fset-devel, so CCing Scott directly and Xach for Quicklisp's convenience.) (defconstant Tuple-Key-Number-Size (ecase (integer-length most-positive-fixnum) (62 41) ; SBCL, 64-bit (61 40) ; ECL, 64-bit (60 40) ; SBCL, OpenMCL, Scieneer CL, 64-bit (48 32) ; CLISP, 64-bit (31 18) ; Symbolics L-machine, I-machine (29 17) ; Allegro, CMUCL, SBCL, LispWorks (most), ECL, 32-bit (24 15) ; CLISP, 32-bit (23 14)) ; LispWorks 4 on Linux "This limits the number of tuple-keys that can exist in a session.") (defconstant Tuple-Value-Index-Size (ecase (integer-length most-positive-fixnum) (62 21) (61 21) (60 20) (48 16) (31 13) (29 12) (24 9) (23 9)) "This limits the number of key/value pairs in any tuple.") Cheers, -- Nikodemus

[fset-devel] FSet on ABCL
by Alessio Stalla 09 Nov '11

09 Nov '11

Greetings, as part of my nth plan to conquer the world (which of course I won't unveil right now), I tried FSet on ABCL. I managed to make it run, but I had to patch it; you can find the patch attached (it's taken against the version in Quicklisp, but I believe it's the latest version). Besides some minor #+abcl porting stuff, the one thing that stuck out was the DEFLEX macro for defining global lexical variables, which conflicts with ABCL's implementation of symbol macros. (deflex var) expands basically into (define-symbol-macro var (symbol-value 'var)). The problem: ABCL stores symbol macros in the value cell of symbols, so you can't have a symbol which is both a variable and a symbol macro. Now, I believe deflex as written is non portable CL. This is because accessing the symbol-value of an unbound variable is, to my interpretation, unspecified [*]; and if you use defvar/defparameter with var, then you cannot use it as a symbol macro. Thus, I patched it (taking inspiration from Rob Warnock's version of deflex/defglobal). However, I do think ABCL's implementation is very brittle (and probably conflicting with ANSI as well), because if you setf the symbol-value of a symbol with a global symbol macro attached, you remove the symbol macro! So, I think we should fix it for 1.0.1. Perhaps I can do the fix myself, but we better discuss it before because I fear this might be a deep change. [*] symbol-value ... Accesses the symbol's value cell. [1] value cell n. Trad. (of a symbol) The place which holds the value, if any, of the dynamic variable named by that symbol, and which is accessed by symbol-value. [2] dynamic variable n. a variable the binding for which is in the dynamic environment. [3] I don't think a symbol for which there is no special declaration in scope can be considered to name a dynamic variable, and thus to have a value cell at all.

[fset-devel] Patch to facilitate circular/shared printing.
by Samium Gromoff 04 Jul '11

04 Jul '11

Scott, The tip of my fset repository[1] ports the four PRINT-WB-{SET,BAG,MAP,SEQ} functions to use PPRINT-LOGICAL-BLOCK, replacing depth/length stops handling and adding circular/shared structure printing. -- 1. git://git.feelingofgreen.ru/fset -- regards, Samium Gromoff -- "Actually I made up the term 'object-oriented', and I can tell you I did not have C++ in mind." - Alan Kay (OOPSLA 1997 Keynote)

[fset-devel] Rereading reader bug for collections with non-NIL defaults.
by Samium Gromoff 01 Jul '11

01 Jul '11

Scott, Evaluation of this form fails with an error: (with-standard-io-syntax (let ((*readtable* (copy-readtable *readtable*)) (v (with-default (map) (set)))) (fset::fset-setup-rereading-readtable *readtable*) (with-input-from-string (s (with-output-to-string (s) (write (list v) :stream s))) (read s)))) ..whereas this succeeds: (with-standard-io-syntax (let ((*readtable* (copy-readtable *readtable*)) (v (map))) (fset::fset-setup-rereading-readtable *readtable*) (with-input-from-string (s (with-output-to-string (s) (write (list v) :stream s))) (read s)))) ...which probably suggests that the reader hasn't been conditioned to take care of the trailing "/foo" syntax. -- regards, Samium Gromoff -- "Actually I made up the term 'object-oriented', and I can tell you I did not have C++ in mind." - Alan Kay (OOPSLA 1997 Keynote)

[fset-devel] documentation clipped?
by Joshua TAYLOR 02 Mar '09

02 Mar '09

Hello, I was reading through the FSet Tutorial and came across the following: "2.0 Some comments on functional collections and Lisp Although CL arrays and hash tables are useful only as mutable structures, and lists certainly can be treated as mutable also, I'd like to point out that the functional use of lists is quite common in CL code. For instance, constructing a list by consing things onto it treats the list functionally: each cons remains unmodified after its creation. And there " The paragraph ends abruptly. I take it something is missing? (If it's meant to be a segue into Nested Collections, maybe a trailing ellipsis would be appropriate?)

[fset-devel] Map functions
by Leslie P. Polzer 29 Apr '08

29 Apr '08

Hello, first, let me sketch my problem: I need to manage an ordered inventory of things with a fixed number of slots (in the general sense of the word). Adding new things is mostly done by assigning them to a slot, but it would be nice to be able to just say "add this item" whereupon it will be stuffed into an arbitrary free slot. For removal the same rules are in effect. Slots can be empty, accessing them should return NIL. I have found the MAP type to be most appropriate for this, but I'm running into problems. For example, there's no SETF expander for WITH2, thus rendering ADJOINF non-functional for MAPs. Also, I haven't found any way to find/remove elements in the image of the map, all operations seem to work on the domain only. Can you help me? Should I subclass MAP or another collection type?

[fset-devel] Home Page Alive?
by James Bielman 01 Aug '07

Hi, I'm looking at using FSet in a project, and it looks like it's going to fit my needs quite nicely. I've notice that the web site seems to be down, however. Is there another place to find the documentation? Thanks, James

[fset-devel] Auto-nag: fset please update your webpage
by root＠common-lisp.net 14 May '07

14 May '07

You are being nagged on because you have not created a sensible default webpage for your project. Please do so or you will be nagged again next week. All we ask is that you type in something about the project and perhaps some links to mailinglists etc. See common-lisp.net/project/clo/sp/index.html for a reasonable template. Some projects host their webpages somewhere else (eg. http://common-lisp.net/project/cl-ppcre) and if you're in the same situation you may put the following in your index.shtml: <HTML> <HEAD> <META HTTP-EQUIV="refresh" CONTENT="0;URL=YOURURLGOESHERE"> </HEAD> <BODY> </BODY> </HTML> Any questions? You can reach the author of this cronjob at clo-devel(a)common-lisp.net Thanks!
