Getting started instructions not working

[libbooze]

Description of the bug:

First issue is that I guess due to holidays there were no recent releases so
VERSION="$(date -d yesterday +0.0.0-0.nightly.%Y.%m.%d)"
does not work.

Second issue is that when I manually change date running the steps fails with:

forty_two.carbon:1:12: error: member name Printnot found inCorefn Run() { Core.Print(42); }

I presume language changed since documentation was written.

Link to documentation:

https://github.com/carbon-language/carbon-lang?tab=readme-ov-file#getting-started

What should it say instead?

would be nice if there was easy way to point to last release.
would be nice if program we are echoing compiles.

Any other information, logs, or outputs that you want to share?

I reduced the script so maybe bug is on my side, although I doubt it. This is my exact script:

# A variable with the nightly version from yesterday:
#VERSION="$(date -d yesterday +0.0.0-0.nightly.%Y.%m.%d)"
VERSION="$(date -d '3 days ago' +0.0.0-0.nightly.%Y.%m.%d)"

# Get the release
wget https://github.com/carbon-language/carbon-lang/releases/download/v${VERSION}/carbon_toolchain-${VERSION}.tar.gz

# Unpack the toolchain:
tar -xvf carbon_toolchain-${VERSION}.tar.gz

# Create a simple Carbon source file:
echo "fn Run() { Core.Print(42); }" > forty_two.carbon

# Compile to an object file:
./carbon_toolchain-${VERSION}/bin/carbon compile \
  --output=forty_two.o forty_two.carbon

# Link to an executable:
./carbon_toolchain-${VERSION}/bin/carbon link \
  --output=forty_two forty_two.o

# Run it:
./forty_two

yes the Core.Print function has moved into the "io" library in Core. You can have a look at the examples/ directory for code that is more likely to be working, but I will send a fix for the docs, thanks for pointing it out.

The missing nightly is because the actions started failing, not because of the holidays per se: https://github.com/carbon-language/carbon-lang/actions/runs/12450480722/job/34757345786
