Hi is there any kind of quality-checking before a library is implemented into the arduino-IDE?
I tried the SPIFFSINIFile-library. The example-code on GitHub - yurilopes/SPIFFSIniFile: ESP8226 and ESP32 library to parse ini files
does not compile
best regards
Stefan
No, Arduino doesn't do any quality checking of 3rd party libraries. The closest they come is rejecting any libraries that contain symlinks or executables, since these might be used for malicious purposes.
There are thousands of 3rd party libraries in the Arduino Library Manager index and it would be very difficult to do any completely automated testing of these libraries, since many only work on a specific board.
The responsibility is on the 3rd party library developer. They should have automated testing to help ensure quality of their development work and contributions, then thoroughly test the library before making a release.
If you post the error you are having, people here on the forum may be able to provide assistance.
Hello pert,
thank you for moving the question to the right forum.
I was unsecure where to post it.
OK I'm using Arduino IDE 1.8.12
I have installed the IniFile-file library (which supports SD-cart inside)
And I have installed the SPIFFSIniFile-library
If I do a plain copy&paste of the sourcecode given in the example
/*
Remeber to upload the data directory to your board!
Serial baud rate in this example is 9600
*/
#include "FS.h"
#include <SPIFFSIniFile.h>

break;
case SPIFFSIniFile::errorFileNotFound:

case SPIFFSIniFile::errorFileNotOpen:

I get these error-messages:

guys what the hell did the author tweak and screw up his Arduino-IDE to make such a code compiling?
OK any help would be much appreciciated.

OK as nobody is answering I developed another solution:
Found the StackString-library and installed this library through the library-manager of the Arduino-IDE.
strings in StackString do not eat up all RAM over time like standard strings do.
You have to write a bit more of code to use it but IMHO the security of not violating the values of other variables like standard strings CAN do ist worth it.
The StackString-library offers functions like .find and .substring which make parsing a string a breeze.
Then I wrote my own little KISS ini-parser. I don't need ini-Files with sections thouw it would be pretty easy to add ini-filesections to the code (you could use .find("[Mysectionname]") or .startsWith("[Mysectionname]") for this.
Here is a demo-Code that shows the use of the StackString-Library
#include <StackString.hpp>
using namespace Stack; // it is very important to have this line of code. Otherwise the code won't compile
StackString<50> myString = StackString<50>("Hello, World!");
void setup()
{
Serial.begin(115200);
Serial.println();
Serial.println();
Serial.println(myString.c_str());
myString.prepend("Everybody say: ");
Serial.println(myString.c_str());
myString.append(" How are you doing?");
Serial.println(myString.c_str());
Serial.println();
StackString<100> myString1 = StackString<100>("http://arjenstens.com");
Serial.println( "012345678901234567890");
Serial.println( "| | | ");
Serial.println( myString1.c_str() );
Serial.print("first occurence of letter 's' is position ");
Serial.println( myString1.find("s") );
Serial.print("second occurence of letter 's' is position ");
Serial.println( myString1.find("s", 2) );
Serial.println();
//0123456789012345
StackString<64> MyIniStr = StackString<64>("123456789=abcde");
StackString<64> MyIniIdentifier = StackString<64>("");
StackString<64> MyIniValueStr = StackString<64>("");
Serial.println("0123456789012345");
Serial.println("| | |");
Serial.println("123456789=abcde");
int PosOfEqualSign = MyIniStr.find("=");
Serial.print("PosOfEqualSign:");
Serial.println(PosOfEqualSign);
int Len = MyIniStr.length();
Serial.print("Len:");
Serial.println(Len);
MyIniIdentifier = MyIniStr.substring(0,PosOfEqualSign);
//MyIniIdentifier = MyIniStr.substring(0,9);
Serial.print("MyIniIdentifier =#");
Serial.print(MyIniIdentifier.c_str());
Serial.println("#");
MyIniValueStr = MyIniStr.substring(PosOfEqualSign + 1, (Len - PosOfEqualSign - 1));
Serial.print("MyIniValueStr =#");
Serial.print(MyIniValueStr.c_str());
Serial.println("#");
Serial.println();
StackString<10> myNumberAsString = StackString<10>("1133");
int MyNumberAsInteger = myNumberAsString.toInt() * 2;
Serial.print("myNumberAsString =#");
Serial.print(myNumberAsString.c_str());
Serial.println("#");
Serial.print("MyNumberAsInteger = myNumberAsString.toInt() * 2=");
Serial.println(MyNumberAsInteger);
Serial.println();
Serial.println( myString1.c_str() );
Serial.print("does the string above start with 'https'? ");
if (!myString1.startsWith ("https"))
{
Serial.println("no !");
Serial.println();
}
Serial.print("does the string above start with 'http'? ");
if (myString1.startsWith ("http"))
{
Serial.println("YES !");
Serial.println();
}
}
void loop()
{ // put your main code here, to run repeatedly:
}
