Nim experiments

Install nim

Follow the steps at https://nim-lang.org/install_unix.html instead of brew install nim as the brew approach doesn't install testament.

Create file ~/.config/nim/config.nims and enter the following:

switch("out", "/tmp/nim/") # compiles to this folder

inim - interactive nim

nimble install inim

Add the following to ~/.zshrc:

export PATH=$HOME/.nimble/bin:$PATH

Assumes libpq.dylib is reachable.

brew install libpq

# obtain the location of the library
brew info libpq

ln -s /usr/local/opt/libpq/lib/libpq.dylib /usr/local/lib/

• https://marketplace.visualstudio.com/items?itemName=nimsaem.nimvscode
• https://marketplace.visualstudio.com/items?itemName=formulahendry.code-runner (alternatively, press F6 and nimsaem.nimvscode will run the selected file)

To have Code Runner run in the terminal (to accept user input for example), search for "runinterm" in settings for the Run in Terminal setting, and set that to True.
