Node.js npm version

This module allows you to query the arguments of other processes on macOS.

Module Installation

  • Install libgetargv to your system (see below).

  • Install the module and add to the application's package.json by executing:

    $ npm install --save-optional @camjn/getargv

Saving this module as optional is important because it can only build on macOS, so npm needs to be able to exclude it on other OSs.

Library Installation

  • To get access to libgetargv, sign up for an appropriate sponsorship tier.
  • Clone the libgetargv repo: git clone https://github.com/getargv/getargv.git.
  • Running make install_dylib, installs the library to the /usr/local/ prefix by default; you can change the install location with the PREFIX make variable: make PREFIX=/opt install_dylib.

Building libgetargv

I've built libgetargv on macOS 10.7-13, using only the CLT package, not the full Xcode install. If you need to override variables, do so inside the make command, eg: make EXTRA_CPPFLAGS=-DMACRO EXTRA_CFLAGS=-std=c17 dylib.


import { get_argv_of_pid as get_argv_of_pid_as_string, get_argv_and_argc_of_pid as get_argv_of_pid_as_array } from "@camjn/getargv";
get_argv_of_pid_as_string(some_process_id) //=> "arg0\x00arg1"
get_argv_of_pid_as_array(some_process_id) //=> ["arg0","arg1"]


After checking out the repo, run npm i to install dependencies. Then, run npm run test to run the tests. You can also run npm run console for an interactive prompt that will allow you to experiment.

TS code goes in the lib dir, C code goes in the src dir.

To install this module onto your local machine, run npm install. To release a new version, run npm version patch to update the version number in package.json and create a git tag for the version, and push git commits and the created tag to the git origin; and then run npm publish, which will push the module to npm.
