I ran across this error:
Code Select
> (setq 01Text "Some Text")
ERR: missing argument in function setf
So is this not allowed to use a symbolname starting with a number?
Using: 10.7.4 32Bit Exe
Also showing in DLL-Flavour.

newLISP in the real world / csv to assoc-list
January 24, 2019, 11:06:17 PMInspired by this thread:
Using the artful-newlisp-master/csv.lsp I get a proper list.
The first sublist contains the column header names.
Now I want to transform the list to a assoc-list where the column header names get inserted in each other line as a assoc-key:
So ("Colname1" "Colname2" ....)
and
Lines (Val1 Val2 ....)
gets
(("Colname1" Val1)("Colname2" Val2) ...)
What is the shortest/best approach?

newLISP in the real world / newlisp as Log-parser
December 13, 2018, 03:51:16 AMAfter Long time using newlisp I am still impressed about it's speed.
Yesterday I had a Log-File from our Unix-Host with 588000 lines and 35 MB size.
The newlisp code takes about 40 sec to read each line and parse a complex structure out.
The result file was 10000 lines in 46KB.
No highend-PC.
I like it. One of the best Tools in my Toolbox.

newLISP in the real world / Cmdline-option to keep newlisp instance running
December 02, 2018, 12:32:04 AMI could thing about a cmdline option for newlisp to keep it running.
This means I can call the newlisp.exe simply a second time and instead of starting a second instance it passes the cmdline-args to the running instance and call there a predefined function with it.
Sample:
Code Select newlisp.exe -k funcname-k stands for keep running and listen to the cmdline.
The funcname is called on the second call of the exe and gets the cmdline-aruments of the second call passed.
Second or further call:
Code Select newlisp.exe param1 param2 ....would call:
Code Select (funcname param1 param2 ....)The function is either loaded per cmdline on the first call or is placed in init.lsp
The running instance can be terminated as always by executing the (exit) funktion.
What do you think of such native support?
Of cource it would be possible to build such option with a custom exe with newlisp.dll
Benefit would be to hold huge data in memory with one loading and do processing on it with small individual calls. Kind of newlisp-state-mashine.
Or the other way round.
Start a normal instance and use this for the second call:
Code Select newlisp.exe -r funcname param1 param2 -r stands for use running instance and call function with params.

newLISP in the real world / doc for read with hint to seek
October 27, 2018, 10:53:05 PMI would find it usefull if the doc of the 'read' command could give a advice to command 'seek' (and link) about setting the file-pointer to a different position in the file.

newLISP in the real world / newlisp.dll UTF8 used with purebasic 5.62
October 07, 2018, 05:41:28 AMToday I find a bit time to test a new combination: newlisp.dll UTF8 with purebasic 5.62
Since latest purebasic versions are unicode compiler, it was interesting to use newlisp.dll UTF8 there.
Importing the dll is simple:
Code Select
OpenLibrary(0,"newlisp_utf8.dll")
The call function can look like this:
Code Select
sourcestr.s = GetGadgetText(#Gadget_Form1_String3)
*newlispstr = AllocateMemory(StringByteLength(sourcestr) + SizeOf(Character))
PokeS(*newlispstr, sourcestr, Len(sourcestr),#PB_UTF8)
retstr.s = PeekS(CallFunction(0,"newlispEvalStr",*newlispstr),-1,#PB_UTF8)
FreeMemory(*newlispstr)
SetGadgetText(#Gadget_Form1_Editor5, retstr)
At the end you can (not needed, but cleaner)
Code Select
CloseLibrary(0)

newLISP in the real world / newlisp-js in javascript frameworks
August 25, 2018, 03:29:04 PMBased on the current newlisp-js version I am making progresses in using it from javaScript-GUI frameworks.
One solution is based on NeoAppBuilder/VisualNeo. Currently still in beta.
Test-app:
The GUI tool uses Bootstrap,Angular and Jquery internaly.
Another solution is based on spiderbasic,
Test-app:
The language embeds various js-libs like jquery,dojo,paperjs and others
I expect to be able to use newlisp-js in modern web-apps.
Test-reports from other platforms than Windows wellcomed.
Tested on Win with IE11, Chrome 68, Firefox 61
And on Samsung Handy S3 with Chrome

newLISP in the real world / wish: option for pretty-print
April 01, 2018, 12:41:23 AMI had a wish for improving pretty-print.
Idea: I had problems in reading complex, nested lists which were saved with default pretty-print.
The problem is that on the first line are several list-items and on the following line one list per line.
For simple list it is pretty enough to be readable.
When symbols gets longer and more complex lists, I would like to see an option to use open-paranthese as line-seperators. The option could be activated by using a "(" instead of an integer.
Each open-paranthese would increase indent and the corrosponding close paranthese would decrease.
Sample-Call:
Code Select
(pretty-print "(" " " "%1.16g")
Sample Output:
Code Select
(set 'Symbolname
'("MainItem"
("Item1" "Value1")
("Item2" "Value2")
("Item3" "Value3")
("Item4" "Value4")
("Sublst"
("SubItem1" "SubValue1")
("SubItem1" "SubValue1")
("SubItem1" "SubValue1")
("SubList"
(
("SubListItem1" "SubListValue1")
("SubListItem1" "SubListValue1")
("SubListItem1" "SubListValue1")
)
)
)
)
)
What do think?

newLISP in the real world / Best way to slice a long list in sublists
October 24, 2017, 12:47:37 PMI have a long flat list of params parsed from a csv file.
For example it has for eample 49 items and I know that they are a mulitple of 7 elements.
What is the most elegant way to slice the list into a list with 7 sublists with each 7 items?
In a loop with (slice 0 7) and so on?

newLISP in the real world / newlisp.dll in windows 10 load error
November 23, 2015, 11:08:02 AMI noticed that some of my apps using newlisp.dll throw an error running under win 10.
After getting access to win 10 on my sons laptop I dig into the problem and find the reason:
Doing this pascal-code in my delphi host app does give trouble under win 10:
Code Select
DllHandle := LoadLibrary( Pchar( 'newlisp.dll' ));
Giving only the dll-name let the system search in the search-hierachy of windows.
This works on all windows before windows 10.
Because of security concerns MS seems to block now this loading.
The workaround/solution here is to give a full path and filename to LoadLibrary.
So I load the dll now from the same directory as the host-exe.

newLISP in the real world / newLISP for win universal apps ?
October 12, 2015, 10:39:24 PMMaybe a thing for the future: Would it be possible to use newLISP for win universal apps ?
Since universal apps are based on HTML and javascript, it let me think about using newLISP-js.

newLISP and the O.S. / java 8 no more on WIN XP
January 25, 2015, 05:13:02 AMToday on my older WIN XP box a java update run and a message pops up that java 8 should run only on a newer OS.
And you could use java 8 only on your own risk on XP.
Note: First feature is Lambda Expressions!!
Hopefully newLISP will continue to run on the latest java 7.

newLISP in the real world / newlisp-js IDE
January 05, 2014, 02:54:22 AMPossible improvment for your newlisp-js IDE here:
When nothing is selected in the Input area, the Manual button should link to:
When text is selected (for example println) then call:
Then we have context-help.
(Not sure if this is supported by textarea)
Some discussion here:
