I couldn't be bothered to think of a better name.
This is a wrapper over the SML/NJ REPL, designed to mimic a "compiler extension" for the SML/NJ compiler, that implements "C-like syntax". Currently, it can do most of the things through the first 6 weeks of 150, minus datatypes.
It also has options for a few 150-related jokes. This was for my 150 interview. Please consider my candidacy.
I'll bet you've never used Unix pipes in SML before.
To replicate the effect that I had, you need to run sml sources.cm finish.sml <flags> > /dev/null. Obviously, this gives away the trick immediately, so the
actual way to do this is that you should alias (in your shell) the command sml
to instead run sh top/mock.sh, which adds in the extra arguments to where they
need to go.
The reason why you need to pipe into /dev/null is so that the actual output
from compiling sources.cm and finish.sml does not show up. This maintains
the illusion that the only thing happening is booting up the SML/NJ REPL.
sources.cm compiles the lexer and parser that are used to interpret and
translate the modified syntax. finish.sml runs the actual command-line
nonsense, as well as some systems-level stuff that completes the illusion.
You can see the various commands added via running sml -h (where sml is
aliased to the included Bash file). Alternatively, sml --special-help
describes some funny options.
Have fun!
