# Vconf

Vconf is a small V library for loading in configuration from a TOML config file
and/or environment variables.

## Usage

Vconf works by reading configuration variables from both a TOML file and/or
environment variables.

```v
struct Config {
pub:
	port                 int    = 8000
	log_level            string = 'WARN'
	pkg_dir              string
	data_dir             string
	api_key              string
	default_arch         string
	global_schedule      string = '0 3'
	base_image           string = 'archlinux:base-devel'
	max_log_age          int    = -1
	log_removal_schedule string = '0 0'
	collect_metrics      bool   [empty_default]
}
```

This is an example of a configuration struct. The configuration can then be
processed as follows:

```v
conf := vconf.load<Config>(prefix: 'VIETER_', default_path: config_file)!
```

Configuration is defined completely as a V struct.

##  Progress

My goal is to eventually support most types that the TOML library supports.
Currently supported:

- [ ] `Date`
- [ ] `DateTime`
- [ ] `Time`
- [x] `bool`
- [ ] `f32`
- [ ] `f64`
- [ ] `i64`
- [x] `int`
- [x] string
- [ ] `u64`
- [ ] `[]Any`
- [ ] `map[string]Any`

With the last one, my plan is to have this be another struct inside the
top-level one. Configuration could then be defined recursively.
