concat two element, invoid array became list in silent (define (concat) (apply _concat (args))) (define (_concat @x @y) (cond ((atom? @x) (cond ((atom? @y) (cons @x @y)) ((array? @y) (cons @x @y)) ((list? @y) (push @y (list @x) -1)) (true (error "error concat data")))) ((array? @x) (cond ((atom? @y)...

I think array should have empty array, Just like other language.

I think "Not empty array" is a design error.

When I add a array to list, then index it, it would became list in silent. newLISP v.10.7.0 32-bit on Windows IPv4/6 libffi, options: newlisp -h > (array? ((list 1 (array 3 '(1 2 3)) 3) 1)) nil > (list? ((list 1 (array 3 '(1 2 3)) 3) 1)) true I think array as value, when transfer to expression, it s...

ssqq

Code: Select all

> (empty? (array 2 '(1 2)))
ERR: list or string expected : (1 2)

I think any check function could accept any type of data.

ssqq

thanks, I think macro may be ok!

ssqq

some newLISP builtin function is destructive, If user want design destructive function, how to make it?

for every argument passed into user function is value, not reference only if value is stored in a functor.

ssqq

I found '() is not nil or true? value:

Code: Select all

> (nil? '())
nil
> (true? '())
nil
> (empty? '())
true
> (list? '())
true
> (= '() '())
true

for nil and true is only bool value in newLISP, so everything should be judged with nil? or true?

thanks, I get it use 10.6.0, I would try it use 10.7.0.

when I use 10.7.0 it is ok.

ssqq

I think this is a bug.

symbol table should permit "fn" or "lambda" as name.

YAML is suit for view, C and C++ YAML LIB have been upgrade to 1.1.

http://pyyaml.org/wiki/LibYAML

Anyone could test it in newlisp.

ssqq

Website is so quickly, If give some compare data with other website framework. I think maybe Google would interest with it.

I think first lambda expression should is 'lambda: > (first (lambda (x y) (+ x y))) lambda > (first (fn (x y) (+ x y))) fn > 'lambda lambda > 'fn fn > (cons 'fn '((x y) (+ x y))) (fn (x y) (+ x y)) Why newLISP use args as first elements of lambda expression? Why could not quote *lambda* and *fn*?

ssqq

I think newlisp should add function *defined?*, for all not defined variable is *nil*.

Code: Select all


> (defined? 'var) ; --> nil
> (set 'var nil)
> (defined? 'var) ; --> true
> (delete 'var)
> (defined? 'var) ; --> nil

I like newLISP. If put the source code to github. maybe more people could participate in this Project. If Add some function used 'Test` in newLISP core like this: ( is (expression args) result, messsage)) ( ok expression-is-true message) Then could add some test-case in core. So many people could se...

I write a tool for checking un-declare symbol of newLISP code, it need improve more. https://github.com/songzan/Spp/blob/master/strict.lsp If you want test it, pls link it first (or change default *main-args* number): On Winxp: > newlisp -x strict.lsp strict.exe > strict your-script.lsp On Linux: > ...

When I use the key of *up* *down* *right* *left* in REPL with Ubuntu 14.04 shell:

Code: Select all


ssqq@X61:~$ newlisp
newLISP v.10.6.0 32-bit on Linux IPv4/6 UTF-8, options: newlisp -h

> ^[[D^[[C^[[B^[[A^[[A^[[C

I try other shell or ssh tool, same problem. If I missed some compiler file when built newLISP?

ssqq

I found if *eval* a symbol, then *eval* the context symbol with this symbol prefix would throw a error.

Code: Select all

> (eval 'c)
nil
> (eval 'c:var)
ERR: context expected in function eval : c
> (context 'c)
c
> (eval 'c:var)
nil

ssqq

yes, When we import some module, imported symbols list is useful, when it is not useable, delete it from symbols table also is a good habbit.

Hi, I write a newLISP syntax check tool with perl6.

https://github.com/songzan/Spp/blob/master/Newlisp.p6

Could pass with all lsp file with contribute package.

found following error:

module/unix.lsp line: 59

Code: Select all

    (import library "getuid")`

end char is *`*.

ssqq

thanks, it is a good idea.

When delete the lexical symbol, the lambda could not work, even re-set it with nil or other value: > (define (sub-name lexical-args) (add lexical-args)) (lambda (lexical-args) (add lexical-args)) > (sub-name 2) 2 > (delete 'lexical-args) true > (sub-name 2) ERR: symbol is protected : nil called from...

Thanks, I use *lambda?* to check if expression starts with *fn* or *lambda*. (lambda? '(fn (x) (add x))) ;--> true to get the symbol of *fn* or *lambda*, could use following code: (sym "fn") ; --> fn (sym "lambda") ; --> lambda then, could check it. > > (list 1 (sym "lambda") (sym "fn")) (1 lambda f...

ssqq

yes, Perl have too much difference from newLISP.

All of us want write stable, clear, easy to maintain code, also want use for reference from other language have learned.
