flox print-dev-env command


flox-print-dev-env - print shell code that can be sourced by bash to reproduce the development environment


flox [ <general-options> ] print-dev-env [ <options> ] <package>


Print a shell script that can be sourced by the current shell to both activate a project flox environment (if it exists) and the build environment for the corresponding package. This allows you to enter a development environment in your current shell rather than in a subshell (as with flox develop).


General Options

The following options are used specifically by flox and must be specified before the <command> argument.

-v, --verbose
Verbose mode. Invoke multiple times for increasing detail.

Debug mode. Invoke multiple times for increasing detail.

-V, --version
Print flox version.

Print flox installation prefix / Nix store path. (flox internal use only.)

Force execution in flox-bash (flox internal use only.)

[--stability <stability>]
Selects the set of nixpkgs to be used as a basis
