newLISP in the real world / How to make load chain properly?
November 18, 2012, 11:05:47 AMTried to find the info in documentation and other forum topics but couldn't.
The question is about load function.
Say I have three files: main.lsp, lib/a.lsp, lib/b.lsp
How do I load file b.lsp into a.lsp if i load a.lsp into main.lsp?
This doesn't work:
Code Select
; main.lsp:
(load "lib/a.lsp")
; a.lsp:
(load "b.lsp")
because current directory is defined by the directory where main.lsp resides, not the file being loaded.
I don't want to write absolute path as all files il lib directory can constitute a single library, and the lib directory can take arbitrary location in the local filesystem.
Is there some way to load b to a, however?

newLISP in the real world / (float) with elements of the list
November 07, 2012, 07:25:41 AMCode Select
(set 'lst '("23" "hello" "3.14"))
(float (lst 1))
; -> "3.14" instead of nil
Why so?

newLISP in the real world / Colored output in REPL mode and (help) function
March 26, 2012, 12:37:47 AMCould anyone advice me how to make colored output in REPL (in Linux)?
Also I thought it would be good to have something like:
Code Select
> (help curry)
Syntax: (curry func exp)
Transforms func from a function f(x, y) that takes two arguments into a function fx(y) that takes a single argument. curry can be used on all functions taking two arguments.
Examples:
(set 'f (curry + 10)) → (lambda () (+ 10 (args 0)))
(map (curry list 'x) (sequence 1 5)) → ((x 1) (x 2) (x 3) (x 4) (x 5))
for more comfortable learning of the language in the interactive mode. Plus it could be not only built-in functions, but also user-defined functions with help information somewhere around:
(define (my-func)
"...help information..."
....
or
# formatted help information
(define (my-func)
...

newLISP in the real world / "double symbol"
March 13, 2012, 04:32:36 AMCode Select
(symbol? ''a) ; -> nil
; but
(symbol? (eval ''a)) ; -> true
What type of object is ''a (or e.g. '''''''''''''''''''''a) then?

Dragonfly / newLispization of server/client code
June 14, 2011, 10:44:07 AMSeems, I succeeded to rewrite my Java-made site using newlisp and Dragonfly framework.
It's here:
It's in Russian, so short description: this is a site (clone, official website here:
It's a front-end. In jsp I implemented back-end as well, and newlisp implementation is to come. But nowadays I would prefer new approach, using ajax and edit windows over shadowed page, not separate interface. Here with my laziness I meet one small barrier - that I have to write code using html, css, javascript in addition to newlisp (which I like more and more). I all the time forget the syntax of javascript and names of tags and their attributes! :-) So I have idea if to substitute all this extra syntax to the plain Lisp? That is everything - html, css styling, javascript and its frameworks (I choose dojo) can be facaded by lisp code? On the server side at request, newlisp will generate css files, js files, ajax (I would call them "listeners"), attach them to generated html file (I would call it a "loader" as it loads client code to the browser) and send them in response back to user.
If some persistent API to appear, it will be convenient to turn on different javascript frameworks, provide flexible css styling (like handling paddings and backgrounds for many blocks at once), something like input fileds-relational db mapping etc.
Maybe this idea already been implemented somewhere by someone?

Dragonfly / JSON transformation
June 03, 2011, 08:17:26 AMWhile using plugin artfulcode/json.lsp version 2.0 I tried to build a string in json format (lisp->json function). It turned out that I can not pass variables in the expression (or I don't know how to do it).
Example:
Code Select
(setq var1 "some value")
(Json:lisp->json '(("var1" var1) ("a" 2) ("var2" '(("b" 3) ("c" (+ 2 2))))))
;; will result in -> { "var1": "var1", "a": 2, "var2": { "b": 3, "c": ["+", 2, 2] } }
So I had to change a bit the file json.lsp (wrapping eval around second element of the pair), for it were able to output correct result:
Code Select
;; -> { "var1": "some value", "a": 2, "var2": { "b": 3, "c": 4 } }
Is it ok, or I again, as newbie to newlisp, missed something trivial?

newLISP in the real world / utf8 output from mysql
May 20, 2011, 02:43:36 PMI am trying to port my website and cms from tomcat/java to dragonfly/newlisp. The site is in Russian (cyrillic), so the problem: when I retrieve data from mysql database and print it through dragonfly's view I get this: "208148208183195166209131208180208182209139209133209138195166209131" instead of "Дзæуджыхъæу" (as an example).
I use mysql.lsp module of newlisp. The default encoding of mysql database is utf8, encoding of page in browser is also utf8. The same result (two-byte code in numbers, but not symbols themeselves) I have got when I used postgresql database with postgres.lsp.
My question is: did I miss something very trivial, or I will have to change mysql.lsp in some way?
If you can give me some hint? Thank you in advance!
Denis
