rbgo

Overview ¶

Command rbgo is the CLI front-end for the embedded-ruby interpreter.

A closed-world binary (produced by `rbgo build --closed`) instead uses the generated main in closed_main.go, which runs a single embedded program with no front-end linked — so this CLI is excluded from that build.

rbgo [options] [--] <file.rb> [arguments...]   interpret, ARGV = the arguments
rbgo [options] -e "<code>" [arguments...]      run a one-liner
rbgo run ...                                   the same, spelled explicitly
rbgo build [-o out] <file.rb>                  AOT-compile the program's
                                               lowerable methods to native Go
                                               and link a specialised binary
                                               (see internal/aot and
                                               docs/aot-compiler.md)

The options and the script/ARGV boundary follow ruby.c; options.go holds the rule and the citations.

`repl` arrives in a later phase (plan-rbgo.md §17).
