ghul.cli 0.1.0

ghūl CLI

Run a ghūl script directly, without a project file — on Linux, including via a #! shebang line.

#!/usr/bin/env ghul

entry(args: string[]) is
    IO.Std.write_line("hello, {if args.count > 0 then args[0] else "world" fi}");
si

chmod +x greet.ghul
./greet.ghul world
# hello, world

Or run it directly without the shebang:

ghul greet.ghul world

Installing

dotnet tool install -g ghul.cli

On first use, ghul installs its own private copy of ghul.compiler (into ~/.local/share/ghul-cli/tools) if one isn't already there — nothing else to set up first.

How it works

Each script is compiled once per script-content-and-compiler-version pair and the result cached under ~/.cache/ghul-cli/scripts; a later run of an unchanged script skips straight to running the cached build. Everything after the script path is passed through unchanged as the running program's own command-line arguments, and its exit code becomes ghul's own.

There are no reference-assembly options: ghul relies entirely on what ghul.compiler resolves on its own, and doesn't try to add anything it wouldn't already find.
