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.
npm install
Installation on Windows does the following:
- Downloads
cygwininto a.cygwinfolder - Installs various utilities required on
cygwinfor OCaml & Reason -rsync,patch,mingw, etc. - Sets up OPAM to point to the Windows repository: https://github.com/fdopen/opam-repository-mingw/
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'
An API is also bundled:
const { bashExec } = require("esy-bash")
await bashExec("ls -a")
