Reading from dat, or ini

Reading from dat, or ini - 09/22/08 02:28

so far I only know of one way to read from an INI, or DAT, but I would like to know if there is a way to read from one of those files in a standard ini format..

In case you're not familiar with the standard ini format it looks something like this:

Quote:

[topic]
subject=answer
subject2=answer2
[topic2]
subject=answer

So in other words I'd like to know if I could specify the topic, then obviously specify the subject and receive the answer..

Or even if there is a way to do it without the topics would definitely help, so I can just call out the subject and receive the answer

Any help appreciated, thanks

The following is probably not helpful at all:

A6.60
http://testdummy93.tripod.com/3DGS/3DGS_index.html
tDe.zip -> tDe.dll + tDe.wdl

Code:

STRING sAnswer[256];
// set path
ifdef DEVELOP;
inif_wp(work_dir, "questions.ini");
ifelse;
inif_wp(exe_dir, "questions.ini");
endif;

inif_wSect("topic"); 	// set section
inif_rs("subject", "?", sAnswer);	// read string
// ...
inif_rs("subject2", "?", sAnswer);	// read string
// ...
inif_wSect("topic2");	// set section
inif_rs("subject", "?", sAnswer);  // read string
// ...

thanks looks good, but I take it there is currently no way to do it without a plugin?

read:
1. read the ini file in a text object
2. normalize the text object
3. search for your [topic]
4. search for your key=
5. return the value

add/delete:
1. read the ini file in a text object
2. create a temp dest. textobject
3. copy untouched entries to the dest textobject
4. when found your [topic] your key=
change the value(change) or skip copying the line(del)
6. write the dest. textobject

hmmm can't really tie that to an answer

Also mercuryus, do you have any code example, I can only assume from your message that you mean to open the ini file in a

Code:

TEXT whatever = {}

however I can't really find any reference in the manual as to how to search an ini/txt file or how to open the ini file in a text object

but I appreciate both of your help, and am awaiting a reply, thanks a bunch

Code:

// not complete; just an example
// tested quickly; may have errors
TEXT ini_t1 {
	strings = 256;

}
var ini_nLinesC = 0;
var ini_bSect = 0;
STRING ini_sValue[256];
STRING ini_s1[256];
STRING ini_s2[256];
STRING ini_s3[256];
var ini_n1 = 0;
var ini_n2 = 0;

function inif_get(_sSection, _sKey) {
	ini_n1 = 0;
	str_cpy(ini_sValue, "");
	ini_bSect = 0;
	while(ini_n1 < ini_nLinesC) {
		if (str_stri(ini_t1.string[ini_n1], "[") == 1) {
			if (ini_bSect) {
				return(0);
			}
			str_cpy(ini_s1, ini_t1.string[ini_n1]);
			str_clip(ini_s1, 1);
			str_trunc(ini_s1, 1);
			if (str_cmpi(_sSection, ini_s1)) {
				ini_bSect = 1;
			}
		} else {
			if (!ini_bSect) { goto(next1); }
			ini_n2 = str_stri(ini_t1.string[ini_n1], "=");
			if (ini_n2 == 0) { goto(next1); } 
			str_cpy(ini_s2, ini_t1.string[ini_n1]);
			str_cpy(ini_s3, ini_s2);
			str_trunc(ini_s2, (str_len(ini_s2) - ini_n2) + 1);
			if (str_cmpi(_sKey, ini_s2)) {
				str_clip(ini_s3, ini_n2);
				str_cpy(ini_sValue, ini_s3);
				return(1);
			}
		}
		next1:
		ini_n1 += 1;
	}
	return(0);
}

function inif_load(_sFile) {
	ini_nLinesC = txt_load(ini_t1, _sFile);
	return(ini_nLinesC);
}

//...
inif_load("questions.ini");
inif_get("topic2", "subject");
// do something with ini_sValue
