Nim: How to write a file

Writing a file is as straight-forward as reading one:

let text = "Hello World!"
writeFile("hello.txt", text)

Writing each line incrementally is also similar:

proc writeHello() =
  let lines = ["Hello", "World", "!!"]
  let f = open("hello.txt", fmWrite) # fmWrite is the file mode constant
  defer: f.close()

  for line in lines:
    f.writeLine(line)

writeHello()

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.
