Even though it has little adoptation, Nim looks like a cool promissing language! Lets try it out.
Getting started is easy, using choosenim
After answering a few questions, you have Nim installed and can call
Hello World
Nim’s package manager is called Nimble. Lets use it:
nimble init helloworld
Select “Binary” as “package type”.
Nimble will now create a new folder called helloworld. The folder contains a file called helloworld.nimble which describes the new projects dependencies.
A simple hello world program is places in src/hello.nim it looks like this:
# This is just an example to get you started. A typical binary package
# uses this file as the main entry point of the application.
when isMainModule:
echo("Hello, World!")
Like Python, Nim use whitespace (spaces, not tabs) indentation to indicate scoope. No {} is used.
To compile the program, write:
nim c src/hello.nim
or, to compile and run:
nim c -r src/hello.nim
or for projects, you ban use Nimble to build the project:
nimble build
To view the c source of your Nim program, try:
mkdir cache
nim c --nimcache=cache src/hello.nim
Now you can find the c source in the cache folder.
A bit more hello world.
