  • Entirely written in Nim. It can be easily embedded in other Nim programs.
  • Follows the functional and concatenative programming paradigms.
  • Provides a wide range of combinators for advanced stack manipulation and dequoting.
  • Provides a minimal set of data types: integer, floats, strings, booleans, dictionaries, and quotations (lists).
  • Homoiconic, code can be accessed as data.
  • Includes an advanced REPL with auto-completion and history management.
  • Provides a lightweight module system.
  • Provides sigils as syntactic sugar to access environment variables, quoting, defining and binding data, etc.
  • Includes a small but useful standard library for practical tasks.
  • Self-contained, statically compiled into single file.

Don't need all of these features? If you are looking for something even smaller and more bare-bones, check out mn, min's even more minimalist little brother.


The following example shows how to find recursively all files in the current folder that were modified in the last hour:

. ls-r (mtime now 3600 - >) filter

The following example shows how to calculate the factorial of 5 using the linrec combinator:

5 (dup 0 ==) (1 +) (dup 1 -) (*) linrec
