glerd_valid
Gleam Record validators using Glerd metadata
gleam add --dev glerd glerd_valid
1. Describe your records with validation metadata
Example:
pub type User {
/// valid:age:'gte=18, lt=150'
/// valid:name:'gte=3, lt=100'
User(age: Int, name: String)
}
2. Generate Records info
Use Glerd
3. Make module for validators generation
my_module.gleam
import glerd_valid
import glerd_gen
pub fn main() {
glerd_gen.record_info
|> glerd_valid.generate("src", _)
}
4. Gen validators
gleam run -m my_module
