Anything else we might add? / replace slice of list to a element
June 11, 2014, 07:33:25 AM
As manual said:
QuoteSlices or rest parts of lists or arrays as used in implicit resting or slicing cannot be substituted at once using setf, but would have to be substituted element by element.
.



If I want replace a piece of list to a element:


Code Select
(set 'lst '(a b c d e f)
(replace-slice (slice lst 2 3) 'g)
lst --> '(a b g f)

I use:
Code Select
(append (nth '(0 1) lst) 'g (nth 5 lst))

If have any other simple way to get result?

June 09, 2014, 07:30:02 AM
I use Vim to write newLISP code, but I like use newLISP-GS to run code, When I edit and save in Vim, Only way to refresh the content in newLISP-GS is to re-open a tab.



If have any setting option to make it auto-refresh?

So, what can you actually DO with newLISP? / I use newLISP to write a common language parser
May 31, 2014, 10:56:51 AM
I use Perl write a Common Programming language Parser, But it is too complex to maintain and extend.



I try this project with Ruby, Lua, till I study Lisp.



After study Common Lisp, Clojure and Racket, I found only newLISP is suited for this project.



Thanks Latz, newLISP is best suitable language to write a common Programming Language Parser and Transfer.

newLISP in the real world / Re: List or quoted List
May 30, 2014, 05:25:02 PM
I think must have a type of data structure -> 'lazy-list' in newLISP, which would not be evaluted when passed into function as argument. most of list processing function would return a 'lazy-list'.

newLISP in the real world / List or quoted List
May 29, 2014, 04:36:12 PM
function map accept a quoted list as its seconds arguments:



     (map inc '(1 2 3 4 5))



but above expression returned a list? or a quoted list? I think its should be a quoted list, because it could used with second map:



     (map inc (map inc '(1 2 3 4)))



I don't know if it is a macro with map, but the expression with map is evaluted with some delay.



How to know a primitive function is macro or common function?



The evaluted order about primitive function? I know `eval` is first should be evaluate than `println`.

Anything else we might add? / The module search path on Winidows XP
May 15, 2014, 07:17:30 PM
When I use with newlisp-GS:


Code Select
(load "module-xxx.lsp")

on WIndows xp, Only valid path is $HOME.



Could I set many directory to load module without prefix directory name?

Anything else we might add? / int option of regexp
May 14, 2014, 12:01:31 AM
As the manual said:


Code Select
i for PCRE_CASELESS
m for PCRE_MULTILINE
s for PCRE_DOTALL
x for PCRE_EXTENDED

If I want use all this option together, How to write code?


Quote# Perl style

qr/a b .*? d/xms


If it should like:


Code Select
(regex "^a b+ c .*? d$" "abbcnr123d" (+ 2 4 8))

Anything else we might add? / Re: array literal and Tail Call Optimization
May 04, 2014, 06:39:19 PM
Thanks above nice reply.



I understand that Tail Call Optimization and literal of (Array 1 2 3) or (Hash 'a 1 'c 2) could slove by programmer-self use the framework of newLISP(macro or context).

Anything else we might add? / array literal and Tail Call Optimization
May 04, 2014, 06:27:51 AM
Hello everyone,



I found it is same that array literal with list literal, but they are different datatype.



    (list? (array 3)) => nil

    (array 3) => (nil nil nil)

    '(nil nil nil) => (nil nil nil)

    (list? '(nil nil nil) => true



other question, When I run:


   
Code Select
>[cmd](define (fibonacci n)
    (if (< n 2)
    1
    (+ (fibonacci (- n 1))
    (fibonacci (- n 2)))))
[/cmd]
>(fibonacci 100)

My comuter could not print result in ten minutes.



I like recursion, newLISP Hav not Tail Call Optimization?
