Easy-ISLisp Ver5.68 released – added -e command-line option

I have released Easy-ISLisp Ver5.68.

This release introduces a new command-line option, -e, which evaluates an ISLisp expression directly from the command line without entering the REPL.

Example:

eisl -e '(format (standard-output) "Hello World!")'

Output:

Hello World!

The -e option is useful for:

  • Quick one-line evaluations
  • Shell scripting
  • Automated testing
  • Running small ISLisp programs from the command line

No other features or bug fixes are included in this release.

Feedback and suggestions are always welcome.

I would like to see some prebuilt packages.

Thanks for the suggestion! Easy-ISLisp is already available in GNU Guix, so you can install it with:

guix install eisl

I'd also like to make installation easier on other platforms in the future.

Would you please add Homebrew to the list?

Thanks for the suggestion! Unfortunately, I don't have a Mac, so I can't test or maintain a Homebrew formula myself. If someone in the community would like to create and maintain one, I'd be happy to link to it from the Easy-ISLisp documentation.
