Nim: Concatenating strings

Mar 21, 2022

Concatenating strings is one of those topics where for any given language there's a nearly infinite way to achieve the end result. Though typically there will be one or two approaches that are deemed more idiomatic. Here's a couple of the more common approaches within Nim

var a = "This"
a.add(" is a string")
echo "a is now: ", a
# a is now: This is a string
var
b = "This"
c " is a string"
echo "concat: ", b & c
# concat: This is a string

You can also import strutils to use some functions that will look familiar from other languages:

# calling as a method on an array:
import strutils
echo @["a", "b", "c"].join(" ")
# a b c
# or as a function:
echo join(@["a", "b", "c"], "xx")
# axxbxxc
Hi, I'm Glenn! 👋 I've spent most of my career working with or at startups. I'm currently the Director of Product @ Ockam where I'm helping developers build applications and systems that are secure-by-design. It's time we started securely connecting apps, not networks.

Previously I led the Terraform product team @ HashiCorp, where we launched Terraform Cloud and set the stage for a successful IPO. Prior to that I was part of the Startup Team @ AWS, and earlier still an early employee @ Heroku. I've also invested in a couple of dozen early stage startups.
