Subject: | [help-gengetopt] Gengetopt V 2.20 String Parser/Multiple Parsers problems with blank spaces around numerics and order of the arguments. |

Greetings, Would be much obliged if anybody could help me with the
following problems I see with gengetopt 2.20 (latest) as well as previous versions (tried down
to 2.17) using string parser. OS: Linux (tested Open SUSE Linux 10.2 and Mandriva 2006 and
2007 (0x86 and 0x86_64) ) Gengetopt V 2.20 (latest) compiled with GCC 4.1.x. I wrote a client that must take arguments from both CLI as
well as from a file. When parameters are passed on CLI everything works fine
(using cmdline_parser() function). For example: ./client –v –c 0x1234 –print When using cmdline_parser_string() to read flags from a file
line by line I start seeing strange behavior:
I traced the first
problem down to the generated cmdline_parser_internal()
function that has the following code for each and every numeric
option/argument passed to the command: if (!(stop_char && *stop_char == '\0')) {
fprintf(stderr, "%s: invalid numeric value: %s\n", argv[0], optarg);
goto failure; } If for every numeric command argument I comment out this
generated code in the cmdline.c file generated by gengetopt from my .ggo file I
circumvent at least the first
problem. However, this is a rather
crude hack and I’d like to understand the root cause of this
problem is. Is this a bug? I am still trying to find a behavior pattern for the second
problem. That is, - why some order of parameters work and the other don’t
and why the order should matter at all. For one thing it appears that it does not like the long
options to be the first. I am attaching a test case illustrating
the problem. The client can take commands from both command
line as well as a file or just from a file. Example ./client –c 0x1234 –f testfile.txt Or ./client –f testfile.txt Any help will be greatly appreciated. Respectfully, Nikolay V.
