Dear experts,
I have an ini-file and want to read the value of a distinct entry. Within the script the item is found and its value also. Outside the script the value is undefined.
What happens? Any ideas are welcome.
var value;
GetIniValue ("FM-biblio.ini", "04_DoingBook", value);
alert ("value read is " + value);
function GetIniValue (sIniFile, sValueName, sValue) {
// ----------------------------------------------- Read an ini item into a variable
// iniFile must end with a line containing some blanks.
// sValueName is that used in the ini-file (with the prepending #_ (e.g. "04_DoingBook")
var thisLine, match, notFound = true; var regex = { section: /^\s*\[\s*([^\]]*)\s*\]\s*$/, param: /^\s*([\w\.\-\_]+)\s*=\s*(.*?)\s*$/, comment: /^\s*;.*$/ } ; settingsFile = new File($.fileName.replace (/[^\\\/]+$/i , sIniFile)); // method Ric Quatro settingsFile.open("r"); while(true) { thisLine = settingsFile.readln(); if (settingsFile.eof) { // at end of the file we are done break; } if (thisLine === null || thisLine === "") { // skip blank lines continue; } if (regex.comment.test(thisLine)) { // skip comment lines continue; } if (regex.section.test(thisLine)) { // ignore section lines continue; } match = thisLine.match(regex.param); // ignore undefined contents if (match[1] == sValueName) { sValue = match[2];
alert ("GetIniValue: sValueName " + sValueName + ", sValue read = " + sValue); notFound = false; break; // no need to continue while loop } } if (notFound) { alert ("GetIniValue program error - sValueName " + sValueName + " not found in sIniFile " + sIniFile); stop; } settingsFile.close();
} // --- end GetIniValue
The alert on line 34 reports "GetIniValue: sValueName 04_DoingBook, sValue read = no", but outside the value is undefined.
The ini file contains these lines:
... 03_ListItems = yes 04_DoingBook = no 05_Template = FM-biblio-tpl.fm ...
