# minipp
|
||||
|
||||
A lightweight, header-only C++14 parser and writer for the mini config format.
|
||||
|
||||
## Description
|
||||
minipp provides a convenient way to parse and write configuration files in the "mini" format. This format is characterized by its human-readable structure and nested sections, making it ideal for application configurations.
|
||||
|
||||
## Features
|
||||
|
||||
- **Parsing**: Extract values from existing mini configuration files.
|
||||
- Supports strings, integers, floats, booleans, arrays, and nested sections.
|
||||
|
||||
- **Writing**: Generate new mini configuration files.
|
||||
- Create complex structures with nested sections and various data types.
|
||||
|
||||
- **Single Header**: minipp is a single-header library, meaning you only need to include one file.
|
||||
|
||||
## Usage
|
||||
|
||||
To use minipp in your project:
|
||||
|
||||
```cpp
|
||||
#define MINIPP_IMPLEMENTATION
|
||||
#include "minipp.hpp"
|
||||
```
|
||||
|
||||
Then, you can use `minipp::MiniPPFile` to parse and write mini files throughout your code.
|
||||
|
||||
### Example Usage
|
||||
|
||||
```cpp
|
||||
#define MINIPP_IMPLEMENTATION
|
||||
#include "minipp.hpp"
|
||||
|
||||
using namespace minipp;
|
||||
|
||||
int main()
|
||||
{
|
||||
// Make room for a result variable.
|
||||
EResult result;
|
||||
|
||||
MiniPPFile file;
|
||||
result = file.Parse("test.mini");
|
||||
auto& root = file.GetRoot();
|
||||
|
||||
MiniPPFile::Section* gameSection = nullptr;
|
||||
result = root.GetSubSection("game", &gameSection);
|
||||
MiniPPFile::Values::StringValue* nameValue = nullptr;
|
||||
result = gameSection->GetValue("name", &nameValue);
|
||||
MiniPPFile::Values::IntValue* yearValue = nullptr;
|
||||
result = gameSection->GetValue("year", &yearValue);
|
||||
|
||||
// Get a sub-section (section of a section (stated in the MINI file with "[game.window]")
|
||||
MiniPPFile::Section* windowSection = nullptr;
|
||||
result = gameSection->GetSubSection("window", &windowSection);
|
||||
|
||||
MiniPPFile::Section* windowPlatformSection = nullptr;
|
||||
// Get a sub-section by using the dot operator
|
||||
result = gameSection->GetSubSection("window.platform", &windowPlatformSection);
|
||||
|
||||
MiniPPFile::Values::ArrayValue* pointsValue = nullptr;
|
||||
// Retrieve an array by using the relative value path (the game section is a child of the root section)
|
||||
result = root.GetValue("game.window.platform.targets", &pointsValue);
|
||||
|
||||
// Modify the "targets" array by adding a new value
|
||||
pointsValue->GetValues().push_back(std::make_unique<MiniPPFile::Values::StringValue>("haiku"));
|
||||
|
||||
// Serialize the config
|
||||
result = file.Write("test_out.mini");
|
||||
|
||||
return 0;
|
||||
}
|
||||
```
|
||||
|
||||
## Getting Started
|
||||
|
||||
1. **Include minipp**: Add the following line to your file:
|
||||
|
||||
```cpp
|
||||
#define MINIPP_IMPLEMENTATION
|
||||
#include "minipp.hpp"
|
||||
```
|
||||
Note, that you must define MINIPP_IMPLEMENTATION exactly once in your project!
|
||||
|
||||
2. **Create a `MiniPPFile` object**:
|
||||
|
||||
```cpp
|
||||
MiniPPFile file;
|
||||
EResult result = file.Parse("your-file.mini");
|
||||
```
|
||||
|
||||
3. **Parse and access values**:
|
||||
|
||||
```cpp
|
||||
// Access sections
|
||||
MiniPPFile::Section* gameSection = nullptr;
|
||||
EResult result = root.GetSubSection("game", &gameSection);
|
||||
|
||||
// Access values
|
||||
MiniPPFile::Values::StringValue* nameValue = nullptr;
|
||||
result = gameSection->GetValue("name", &nameValue);
|
||||
|
||||
// Navigate nested sections
|
||||
|
||||
MiniPPFile::Section* windowSection = nullptr;
|
||||
result = gameSection->GetSubSection("window", &windowSection);
|
||||
|
||||
// .. OR ..
|
||||
|
||||
MiniPPFile::Section* windowSection = nullptr;
|
||||
result = root->GetSubSection("game.window", &windowSection);
|
||||
|
||||
```
|
||||
Note, that the root node cannot have values!
|
||||
|
||||
Also, arrays are contained in an ArrayValue (container of multiple different Values (may also include other arrays))
|
||||
|
||||
```cpp
|
||||
// Handle arrays
|
||||
MiniPPFile::Values::ArrayValue* pointsValue = nullptr;
|
||||
result = root.GetValue("game.window.platform.points", &pointsValue);
|
||||
|
||||
// Modify the array values (or read them)
|
||||
pointsValue->GetValues().push_back(std::make_unique<MiniPPFile::Values::StringValue>("haiku"));
|
||||
|
||||
```
|
||||
5. **Write new files**:
|
||||
|
||||
```cpp
|
||||
result = file.Write("new-file.mini");
|
||||
```
|
||||
|
||||
## Example
|
||||
|
||||
An example mini file is contained in this [repository](test.mini). The full mini file format specilization can be found [here](https://github.com/ToyB-Chan/mini-file-format).
|
||||
|
||||
## Installation
|
||||
|
||||
1. Copy the contents of "minipp.hpp" to a new file in your project.
|
||||
2. #Include "minipp.hpp" after defining MINIPP_IMPLEMENTATION in one single cpp file.
|
||||
3. #Include "minipp.hpp" in any other desired files without the IMPLEMENTATION define!
