Go-based sound change applier for diachronic linguistics and conlanging

scago ⛵️

scago (or sound change applier go) is a go library that can apply a sound change ruleset to a word. It's a useful tool in conlanging communities for artificially creating diachronic change in a constructed language.

The library is inspired by KathTheDragon's SCE, a similar tool implemented in Python.

Usage

Standalone

Make sure that you have the binary folder of your gopath in your shell path (usually $HOME/go/bin; or $GOPATH/bin if your gopath differs from default)

go install go.m5ka.dev/scago/cmd/scago@latest
scago -r "a > e / #_" abacus

Library

package main

import (
	"fmt"
	"go.m5ka.dev/scago"
)

func main() {
    s := scago.New()
    err := s.AddCategory("P", []string{"p", "b", "t", "d", "k", "g"})
    if err != nil {
        fmt.Println("Couldn't add category!", err)
        return
    }
    err = s.AddRule("a > e / _P")
    if err != nil {
        fmt.Println("Couldn't add rule!", err)
        return
    }
    output, err := s.Apply("aba")
    if err != nil {
        fmt.Println("Couldn't apply ruleset!", err)
        return
    }
    fmt.Println(output) // Outputs: eba
}
