envsnap

envsnap is a small command-line utility for generating snapshots of a development or runtime environment to aid in debugging and issue reporting.

It works by having projects define a .envsnap file, which defines various data points that the project finds relevant. This ranges from OS/Arch to package dependencies. envsnap generates a snapshot of the specified data points, making it easy for the user to provide context for their environment when debugging or reporting an issue.

With envsnap, the you no longer has to worry about which data points are relevant when reporting an issue. Let the project define it, and let envsnap collect it.

Installation

From package manager:

# macOS
brew install edaniszewski/homebrew-tap/envsnap

The binary may also be installed from the project's releases page.

You can also use go get:

go get github.com/edaniszewski/envsnap

Usage

envsnap is a simple tool with only two commands:

envsnap init - initializes a new .envsnap config
envsnap render - render your environment based on the .envsnap config

For additional details and usage info, see the help info with envsnap --help.
