your iniparser are not able to parse line with ':' instead of '='
; example
[section]
arg1 : argument one

so I modify your code at line 481 in iniparser.c as following :

    } else if (sscanf (line, "%[^=] = \"%[^\"]\"", key, value) == 2
           || sscanf (line, "%[^=] = '%[^\']'", key, value) == 2
           || sscanf (line, "%[^=] = %[^;#]", key, value) == 2
           || sscanf (line, "%[^:] : \"%[^\"]\"", key, value) == 2
           || sscanf (line, "%[^:] : '%[^\']'", key, value) == 2
           || sscanf (line, "%[^:] : %[^;#]", key, value) == 2) {
        /* Usual key=value, with or without comments */
        /* Usual key:value, with or without comments */
        strcpy(key, strstrip(key));
        strcpy(key, strlwc(key));
        strcpy(value, strstrip(value));
        /*
         * sscanf cannot handle '' or "" as empty values
         * this is done here
         */
        if (!strcmp(value, "\"\"") || (!strcmp(value, "''"))) {
            value[0]=0 ;
        }
        sta = LINE_VALUE ;
    } else if (sscanf(line, "%[^=] = %[;#]", key, value)==2
           || sscanf(line, "%[^=] %[=]", key, value) == 2
           || sscanf(line, "%[^:] : %[;#]", key, value)==2
           || sscanf(line, "%[^:] %[:]", key, value) == 2) {
        /*
         * Special cases:
         * key=
         * key=;
         * key=#
         * key:
         * key:;
         * key:#
         */

I just said it is.

Load data from ini with comments, change some parameters,
then save -- comments will be gone. Is it possible to fix this somehow?

I'm having a LINKER problem.

I'm using MacOS 10.5.6 Build 9G55 and running into the followong linker problem:


ld: unknown option: -Bsymbolic
collect2: ld returned 1 exit status
make: *** [libiniparser.so] Error 1


Has anyone come across this or has an idea how to solve it???

Any help or hints are highly appreciated !

Thanks

I dealt with preserving comments in similar formats before. Basically, -settable by an option-, you can preserve comments by keeping 2 strings for each entry: one with any comment at the end of the line, and one containing all the comments (incl. new lines) _above_ that entry. This preserves the format and is pretty easy to implement in an existing parser.

stenyak:
iniparser is meant to offer an easy way to parse ini files, it is not really a round-trip tool with a 1-to-1 correspondence between file and in-memory data. This being said:
Use iniparser_set() to change setting values
Use iniparser_dump_ini() to create a new ini file containing these values
You will loose the initial file comments by doing so.

How can i..?
a) set values of some settings
b) rewrite the .ini file, so that it contains those changes in the settings.

thanks in advance!

Okay, cool! Thanks!

You can iterate through the keys by using dictionary structure like in iniparser_dump (see iniparser.c).
Here is an example for your case:

int main(int argc,char *argv[]) {
  dictionary *dict;

  dict=iniparser_load("test.ini");
  if(!dict) return EXIT_FAILURE;

  int i;
  unsigned int hh=dictionary_hash("hosts");
  for(i=0;(i<dict->n)&&(hh!=dict->hash[i]);i++);
  if(i==dict->n) return EXIT_FAILURE; // There is no section "hosts" in ini-file.

  for(i++;(i<dict->n)&&strncmp(dict->key[i],"hosts:",6)==0;i++)
    printf("%s = %s\n",dict->key[i]+6,dict->val[i]);

  iniparser_freedict(dict);
  return EXIT_SUCCESS;
}

I just found this library and am interested in using it. One thing I don't see how to do: it is clear how things work if you have a specific key (say, myhostname) and define a value for it (say, foo.bar.com). What doesn't seem possible is some way of iterating through the entries in a section, processing them as you go. For example:

[hosts]

foo = 192.168.1.1
bar = 192.168.1.2
blah = 192.168.1.3

etc...

Am I missing something? This seems like a useful capability, no?
