array in ini file for ini parser stream to parse about inih

[benhoyt]

Hi @chienhsinlin, there's no special provision for this in inih itself, but you can definitely parse comma-separated values in the handler yourself -- use something like strchr or strtok to find the ',' (comma) separators.

If the values for one key are spread across multiple lines, you'll also want to set INI_ALLOW_MULTILINE to 1. This works like Python's configparser multi-line values -- subsequent values have to be indented with whitespace. For example:

[section]
lut_table = 1, 2, 3, 4, 5, 6, 7, 8,
            9, 10, 11, 12, 13, 14, 15, 16

Then you'll receive two separate calls to your handler function with the same section and key name, and you'll need to save the last lut_table array index in a global or something like that.

Hope that helps!

Thanks a lot, It works now after using strtok in the handler to parse each line and tokenize strings with delimiter.

Something like that. as you said idx is global variable.
idx = 0; // as global variable.

        tok = strtok((char *)value,",");
        pconfig.lut[idx] = atoi(tok);
        while(tok!=NULL) {
            idx++;
            tok =strtok(NULL," ,");
            if(tok!= NULL)
                pconfig.lut[idx] = atoi(tok); 
        }

hi, @benhoyt,
for multiple lines like this, seems it's no longer possible to add comments after the value, and the comments either with # or ; are treated as part of value. I feel it's not right. Is this an issue? Thanks.

[benhoyt]

Hi @silly2020, do you have INI_ALLOW_INLINE_COMMENTS turned off? See ini.h for a complete list of settings.

Hi, @benhoyt , thanks for prompt reply.
I didn't turned off INI_ALLOW_INLINE_COMMENTS, it is 1 and INI_ALLOW_INLINE_COMMENTS is ";".
Comments start with ";" in subsequent lines are treated as part of value, comments in the line with name is OK.
Thanks again.
P.S.
I tested with dump in example as below:
ini file content:

[test]
MyName  = value part 1 ; comments OK
 value part 2 ; expect ignore this as comments

what I got with dump:

[test]
MyName = value part 1
MyName = value part 2 ; expect ignore this as comments

@silly2020 Thanks for the report. This is an oversight (bug!) in inih, and differs from how Python's ConfigParser works. Does the latest master version work for you? If so, I'll release this in r56.

[wang-mb]

@benhoyt Yes. I tested again with master version and it works for me. Thank you so much!
