does echo.Reverse() handle pointer parameters?

[msonawane]

in templates Echo#Reverse(name string, params ...interface{}) will always output memory location of param without dereferencing . any workarounds?

[msonawane]

package main

import (
	"fmt"

	"github.com/labstack/echo/v4"
)

func main() {
	server := echo.New()
	server.Add("GET", "/example/:value", func(c echo.Context) error {
		return c.String(200, c.Echo().Reverse("example_route", c.Param("value")))
	}).Name = "example_route"
	a := "d"
	fmt.Println(server.Reverse("example_route", &a))
}

always prints /example/0xc000017350 ( a memory location)

You are doing it wrong. That second parameter to Reverse should not be pointer. Remove & and you are fine.

This is example from tests

echo/echo_test.go
