@p I've wanted to do this for a while, I've kept putting it off but I've thought through a lot of it, so most of what I've been doing is just disambiguating the few places where backwards-compat with POSIX sh requires me to make choices, or just where adding one thing makes the whole parser go a little bit stupid and I have to rearrange things.

You know, fun.

So technically there is a bit of syntactical whitespace. I treat `VAR=value` exactly how POSIX handles assignment, but I treat `pattern = expr` (note the spaces around = ) for elixir-style matching and binding. I have both | and |>. I have the literals #{ and %{ which were so much fun to solve for. Technically, -- is a token because --build was breaking in the shell for a while. I support both `if cond; then ... fi` and `if expr do ... end`. I support atoms, but the POSIX : builtin must be followed by a space.

There's a chance I'm not going to be able to run, say, gentoo scripts through it. I haven't tried yet. But I think my coverage is good enough, and now I have my own shell.

Thank you for listening btw, I always get so self-conscious when I want to talk about these things but no one gets me. I start just shitposting threateningly.
