interpol

interpol is a Go package for doing format-string like string interpolation using named parameters.

Currently, a template only accepts variable placeholders delimited by brace characters (eg. "Hello {foo} {bar}").

Install

First, you need to install the package:

go get -u github.com/imkira/go-interpol

Documentation

For advanced usage, make sure to check the available documentation here.

Example

The following code should use interpol.WithMap function, which simply replaces every key with the corresponding value of the specified map. When run, it should output Hello World!!!.

package main

import (
    "fmt"

    "github.com/imkira/go-interpol"
)

func main() {
    m := map[string]string{
        "foo": "Hello",
        "bar": "World",
    }
    str, err := interpol.WithMap("{foo} {bar}!!!", m)
    if err != nil {
        fmt.Printf("Error: %v\n", err)
        return
    }
    fmt.Println(str)
}
