These libraries are parts of Will.
All libraries are of standard C++ 11 and of cross platforms.
INIReader.h
Read and write ini file. Modified from https://github.com/benhoyt/inih.
example.ini:
; last modified 1 April 2001 by John Doe
[owner]
name=John Doe
organization=Acme Widgets Inc.
[database]
; use IP address in case network name resolution is not working
server=192.0.2.62
port=143
file="payroll.dat"C++ code:
int main()
{
INIReader<CaseInsensitivityCompare, NoUnderlineCompare> ini;
ini.loadFile("example.ini");
int port = ini.getInt("database", "port", 0); //port = 143
int port_ = ini.getInt("database", "port_", 0); //port_ = 143
std::string name = ini.getString("owner", "name", ""); //name = Joha Doe
std::string file = ini.getString("database", "file"); //file = "payroll.dat" (the quotation mark will be kept)
return 0;
}Use setKey and eraseKey after loading the file, then use saveFile to write results to a file.
An example:
int main()
{
INIReaderNormal ini;
ini.loadFile("example.ini");
ini.setKey("", "head", "nothing");
ini.setKey("owner", "age", "30");
ini.eraseKey("database", "port");
ini.setKey("account", "password", "***");
ini.saveFile("example1.ini");
return 0;
}The content of example1.ini after running is:
head = nothing

This library does not support operating the comments.
If a key has been multi-defined, the last value should be taken. Please note all the multi-defined lines EXCLUDE the last one will be ERASED when save!
You have to declare a new class which describes how to deal the key string at the beginning. For an example:
struct CaseInsensitivityCompare
{
bool operator()(const std::string& l, const std::string& r) const
{
auto l1 = l;
auto r1 = r;
std::transform(l1.begin(), l1.end(), l1.begin(), ::tolower);
std::transform(r1.begin(), r1.end(), r1.begin(), ::tolower);
return l1 < r1;
}
};Then declare the ini object:
INIReader<CaseInsensitivityCompare, CaseInsensitivityCompare> ini;Sometimes, if you want to ignore the underlines in the key string, you should declare a new class like this first:
struct NoUnderlineCompare
{
bool operator()(const std::string& l, const std::string& r) const
{
auto l1 = l;
auto r1 = r;
auto replaceAllString = [](std::string& s, const std::string& oldstring, const std::string& newstring)
{
int pos = s.find(oldstring);
while (pos >= 0)
{
s.erase(pos, oldstring.length());
s.insert(pos, newstring);
pos = s.find(oldstring, pos + newstring.length());
}
};
replaceAllString(l1, "_", "");
replaceAllString(r1, "_", "");
std::transform(l1.begin(), l1.end(), l1.begin(), ::tolower);
std::transform(r1.begin(), r1.end(), r1.begin(), ::tolower);
return l1 < r1;
}
};Then declare the ini object like this:
INIReader<CaseInsensitivityCompare, NoUnderlineCompare> ini;A case insensitivity type "INIReaderNormal" has been defined in the head file, you can use it directly for convenience:
typedef INIReader<CaseInsensitivityCompare, CaseInsensitivityCompare> INIReaderNormal;libconvert.h, libconvert.cpp
example.txt:
abc_def_;dddd.
Some examples:
std::string str = readStringFromFile("example.txt"); //str = "abc_def_;dddd."
replaceAllString(str, "_", "."); //str = "abc.def.;dddd."
str = "123,467,222;44";
std::vector<int> numbers = findNumbers<int>(str); //numbers = {123, 467, 222, 44}, scientific notation is supported
std::vector<std::string> strs = splitString(str, ",;"); //strs = {"123", "467", "222", "44"}"splitString" also supports treating continuous spaces as one pattern.
Timer.h
A timer.
Timer t;
// do something...
double elapsed_second = t.getElapsedTime(); //you can check how long the program spentRandom.h
An Mersenne twister random number generator.
Random<double> rand;
rand.set_type(RANDOM_NORMAL);
double d = rand.rand(); //Gaussian(0, 1)
rand.set_type(RANDOM_UNIFORM);
int i = rand.rand_int(100); //[0, 100)DynamicLibrary.h, DynamicLibrary.cpp
This library is a static class and is of single instance.
Get the C-style function pointer like this:
void* func = DynamicLibrary::getFunction("xxx.dll", "xxx");The loaded libraries will be unload automatically when the program exits.
Note: relies on File.
ConsoleControl.h, ConsoleControl.cpp
This library can change the color of the output characters on the console, or change the position of the cursor to format the output.
ConsoleControl::setColor(CONSOLE_COLOR_LIGHT_RED); //change the color of printf, fprintf...
ConsoleControl::moveUp(2); //move up the cursor for 2 linesFile.h, File.cpp
This class can read and write file as a vector of any class.
Some functions are very similar to those of libconvert.
This class can also extract path, main name or extension from a filename string, examples:
std::string filename = R"(C:\Windows\system32\xxx.exe.1)";
std::string result;
result = File::getFilePath(filename); // C:\Windows\system32
result = File::getFileMainname(filename); // C:\Windows\system32\xxx.exe
result = File::getFilenameWithoutPath(filename); // xxx.exe.1
result = File::changeFileExt(filename, "dll"); // C:\Windows\system32\xxx.exe.dllOn Windows, "\" and "/" are both supported. A mixed style string (such as "C:\Windows\system32/xxx.exe.1") can also be treated correctly. It can treat ANSI string correctly, but for UTF8 string the result may be not right. In fact Windows cannot open a file with a UTF8 string file name directly, so this problem is not serious.
On Linux and other Unix-like systems, "\" is not a path pattern, only "/" is effective and it is a single byte character in UTF8 coding, so the result should always be correct.
