thanks
Greetings, and thanks for your report! ============================================================================= Dear Maintainer,
I wanted to format a list of integers in base 16, but the default output was returned in mixed case for the letters A-F. When I added case-conversion to the format string, maxima suddenly ends up in an infinite memory-consuming loop. The exact same format string works in lisp within maxima.
Example:
This works as expected and prints the list as a comma-separated list of hexadecimal integers in upper case:
(%i1) :lisp (format t "~{0x~:@(~x~)~^, ~}~%" '(1000 2000 3000 4000) )
0x3E8, 0x7D0, 0xBB8, 0xFA0
NIL
(%i1)
while this hangs indefinitely (notice exact same string and values)
(%i1) printf(true, "~{0x~:@(~x~)~^, ~}~%", [1000,2000,3000,4000] );
This started happening when I added the case conversion. If I remove it, the output is as expected:
(%i4) printf(true, "~{0x~x~^, ~}~%", [1000,2000,3000,4000] );
0x3E8, 0x7D0, 0xBB8, 0xFA0
(%o4) false
=============================================================================
Take care,
