esy-bash-test v0.0.101

esy-bash

Installation utilities for a bash environment - primed for Reason/OCaml

This package is intended to smooth over cases where OCaml packages rely on Unix utilities or a Bash environment.

On Linux and OS X, this package is essentially a no-op. On Windows, we install an isolated cygwin environment, ready to use for OCaml/OPAM, that we use to run a bash shell.

Installation

 npm install

Installation on Windows does the following:

• Downloads cygwin into a .cygwin folder
• Installs various utilities required on cygwin for OCaml & Reason - rsync, patch, mingw, etc.
• Sets up OPAM to point to the Windows repository: https://github.com/fdopen/opam-repository-mingw/

Usage

Command Line

The esy-bash command runs a script in a bash shell. On Linux and OS X, this just uses the default bash shell. On Windows, this delegates to the installed cygwin environment:

esy-bash echo 'HI'

API

An API is also bundled:

const { bashExec } = require("esy-bash")

await bashExec("ls -a")
