# Fyaml - A Modern Fortran YAML Parser
A lightweight YAML parser written in modern Fortran that supports nested structures, sequences, and various data types. Designed for scientific computing applications needing configuration file support.
## Features
- Parse YAML files into native Fortran data structures
- Support for strings, integers, floats, booleans, and null values
- Handle nested mappings and sequences
- Comment parsing
- Debug logging with configurable levels
- Dot notation access for nested values
- Memory safe with pointer management
## Requirements
- Fortran 2008 compliant compiler (gfortran 8.0+ or ifort 19.0+)
- CMake 3.12+
## Installation
```bash
git clone https://github.com/yourusername/fyaml.git
cd fyaml
mkdir build && cd build
cmake ..
make
make install
```
## Usage
1) Create a YAML configuration file:
```yaml
database:
host: localhost
port: 5432
credentials:
username: admin
password: secret
```
2) Parse it in your Fortran code:
```fortran
program example
use fyaml
type(fyaml_doc) :: doc
type(yaml_value) :: val
call doc%load("config.yaml")
val = doc%root%get("database.host")
print *, "Host:", val%str_val
end program
```
