I strongly recommend not doing this. In particular, it will break in many situations. A few examples: - any file that isn't written in #lang racket such as typed/racket or scribble/manual or ... - any file that doesn't work the same as a sequence of repl interactions. For example, any use of mutual recursion or any shadowing of imported ids - any file that uses forms only allowed in modules, such as `module+` or `provide`.
I'm not sure why `-e` doesn't evaluate in the same namespace as the REPL, but if you put `(enter! "my-file.rkt")` in `enter.rktl` then: $ racket -i -f enter.rktl will do what you want. You can generalize this to: (dynamic-enter! (vector-ref (current-command-line-arguments) 0)) and then: $ racket -i -f enter.rktl my-file.rkt will do what you wanted.
