Nim: How to read a file

Reading the entire file in as a string is a simple one-shot:

let contents = readFile("hello.txt")
echo contents  # prints the entire file

If you want to read it incrementally then:

proc readMyFile() =
  let f = open("hello.txt")
  # Close the file object when you are done
  defer: f.close()

  let line = f.readLine()
  echo line

readMyFile() # will only read the first line

Hi, I'm Glenn! 👋

I've spent most of my career working with or at startups. You'll usually find me working in Product leadership roles, on an advisory board, or maybe as an early investor.

I've been the VP of Product & GTM @ Ockam. I led the Terraform product team @ HashiCorp, where we launched Terraform 1.0, Terraform Cloud, and a whole host of amazing capabilities that 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.
