Darkshell example scripts

Small .dsh scripts that demonstrate language features. Run from the crate root (Rust/darkshell/) unless noted.

# Windows (PowerShell) — forward args if `dsh` is a function
cargo run --release -- .\examples\hello.dsh
.\target\release\dsh.exe .\examples\hello.dsh

# Unix
cargo run --release -- ./examples/hello.dsh
./target/release/dsh ./examples/hello.dsh
Script Topics
hello.dsh echo, pwd, export, quoting
control-flow.dsh if / elif / else, && / `
functions.dsh name() { … }, $1, return, $?
environment.dsh export, unset, prefix VAR=val cmd, child env
redirects.dsh Builtin redirects >, >>, 2>
script-args.dsh $0, $1…, $# (pass extra args on the command line)
builtins.dsh type, help, true / false
source/run.dsh source / . — run another file in the current shell

Tips

  • Use ; between top-level commands in scripts (especially after } closing a function body, and before another name() line).
  • Builtins (echo, etc.) cannot appear inside | pipelines; use external commands (e.g. cmd /c echo on Windows, /bin/echo on Unix).
  • $(command) is not supported in v0 — the shell reports a parse error.
  • redirects.dsh writes examples/redirects-out.txt and examples/redirects-err.txt (safe to delete).
