Many thanks, @itistoday, for you effort on newLISP.

I hope Lutz is in great form, today, just... elsewhere. I`m studing his codebase and I`m starting to feel a profound feeling of respect and regard for him and his code, which is great (IMHO).

I hope to publish something about my project (Ike) in order to find help from you Lisp coders.
I'm a f* C/C++ coder. I know lisp from decades (because I tried to use Xemacs/Emacs for at least 15 years), but I`m still not able to think, in Lisp.
I understand I think just in C, C++ or Smalltalk, but not in Lisp...

I apoligize humbly. I have reproduced your result. I must have done something wrong to get the segfault. Many thanks.

(import "libc.so.6" "strtof" "float" "char*")
(println (strtof "2,07"))

result 2,069999933242798
(with comma)

(import "libc.so.6" "strtof" "float" "char*")
(println (strtof "2.07"))

result 2

(import "libc.so.6" "strtod" "double" "char*")
(println (strtod "2,07"))

result 2,07

(import "libc.so.6" "strtod" "double" "char*")
(println (strtod "2.07"))

result 2

Try with value 2.07. It gives segmentation fault here. I was aware that 3.14 is reported as 3.14 (with some fractional error) but thought it fit only to report the segfault. Thanks. Kindly help.

(import "libc.so.6" "strtof" "float" "char*")
(println (strtof "3.07"))
result = 3

With comma:
(import "libc.so.6" "strtof" "float" "char*")
(println (strtof "3,07"))
result = 3,069999933242798

There is a library, called exodriver downloadable from 'labjack' which gives its library version (2.07) as a 32 bit float through it's function LJUSB_GetLibraryVersion().This I have verified by importing this function in another programming language.

But newLisp v10.76 returns a value 0 instead of 2.07 when the following expression is used:

(import "liblabjackusb.so" "LJUSB_GetLibraryVersion" "float") followed by (LJUSB_GetLibrarVersion) returns a value 0 instead of 2.07.

Perhaps that is because "float" is a cut down version of "double"?

I just checked that there is segmentation fault reading a flost from libc on linux 64 bit, as follows:

(import "libc.so.6" "strtof" "float" "char*")
(strtof "2.07")
yields segmentation fault.

I would appreciate if this issue is resolved.

Yes! That works well now. Thank you. What was wrong with the code?

oh!

This code works.

@vashushpanov Thank you for the script! 🙏

I just tried to run your script on a file that I wanted to clean up. Sadly there was zero output.
I'm running newLISP v.10.7.5 64-bit on Linux IPv4/6 UTF-8, so maybe the regex you use in the script need to be updated? I get no error messages - just zero output!

It is a long time ago I was get this script.
