powscript

library1.1.2jsnpmunverified

Powscript is a bash dialect transpiler written in bash that provides a CoffeeScript-inspired, indentation-based syntax for shell scripting. It compiles to bash (version 4+) or experimental POSIX sh, reducing semantic noise from traditional shell syntax. Features include automatic quoting, safety checks (halt on error, require_cmd/require_env), functional programming constructs, JSON support, module system, and easy async. The current stable version is 0.9 (based on old compiler), with a new compiler in development (beta available). It is self-installing with no external dependencies (bash-only) and targets embedded systems or any environment where bash is available. Key differentiator: no need for gcc or node – pure bash, but not actively maintained.

powscript

✓ ./powscript myscript.pow

✗ npm install powscript

Powscript is a shell script, not a JavaScript package. Download and execute directly.

compile

✓ ./powscript -c myscript.pow > myscript.bash

✗ ./powscript -o output bash myscript.pow

Use -c for compile to bash, --sh for POSIX sh output.

run

✓ ./powscript myscript.pow

✗ bash myscript.pow

Run .pow files directly with powscript interpreter.

Install powscript, create a simple script with argument handling, run it directly, and compile to bash.

wget "https://raw.githubusercontent.com/coderofsalvation/powscript/master/powscript" -O /usr/local/bin/powscript && chmod 755 /usr/local/bin/powscript # Create a test.pow file: cat > test.pow << 'EOF' #!/usr/bin/env powscript require_cmd 'echo' require_env 'HOME' run(@args -- foo) if empty? foo echo "error: please pass --foo <string>" exit 1 echo $args[@] "$foo universe!!" echo "HOME=$HOME" run $@ EOF # Run it: powscript test.pow hello --foo powful # Or compile to bash: powscript -c test.pow > test.bash

Debug

Known issues

gotchaPowscript requires bash >= 4.x. Running on older bash versions will cause errors.

fix

Upgrade bash to version 4 or later, or use a different shell.

affects: <0.0

breakingThe new compiler (beta) is not backward compatible; scripts written for the old compiler may not work.

fix

Check the beta compiler repository for migration notes.

affects: >=0.9

deprecatedProject is in maintenance mode with no active development. The README points to a beta version by another author.

fix

Consider alternatives like shellcheck, bashate, or writing bash directly if future support is needed.

affects: >=1.1.2

gotchaPOSIX sh output (--sh flag) is experimental and may contain bashisms if the powscript uses bash-specific features.

fix

Manually verify output with checkbashisms or stick to bash output.

affects: >=0.9

Errors

Common errors & fixes

bash: powscript: command not found

Powscript not installed in PATH or not executable.

fix

Download and make executable: wget -O /usr/local/bin/powscript https://raw.githubusercontent.com/coderofsalvation/powscript/master/powscript && chmod +x /usr/local/bin/powscript

./powscript: line 1: syntax error near unexpected token `newline'

The powscript file was not downloaded correctly (e.g., missing shebang).

fix

Re-download the raw script from GitHub using wget or curl.

require_cmd: echo: command not found

The required command is not installed on the system.
