It is common to write go text/templates that range over a slice of objects to write out a list or array of items that are separated by some delimiter defined in the template.

In the case of a JSON array of objects, the cleanest output would be a , separating each object without a leading or trailing comma.

Because go template if statements are falsey in that a 0 value will evaluate to false you can write a template as → Continue reading “Go template that properly renders delimiters for a slice of structs”

There are times, mostly for logging and debugging, when you have a slice of a given type that you would like to print to a log file or just convert to a CSV of values.

A quick and easy way to convert a slice to a CSV in Golang is to use the json module to Marshal it a JSON encoded array.

For example

package main

import (
	"encoding/json"
	"fmt"
)

func main() {
	ints := []int64{1, 2, 3,

Sometimes you are making changes to a dependency in another of your go projects and instead of adding a replace command in the go.mod file you want to update that entry in go.mod to point to a specific commit in the repo.

To do so, all that you need to do is:

1. Get the git commit that you want included in your build
2. Change directories to the same directory that your project’s go.mod file resides in which you want to
