setting environment variables with a script before using a state module

[gaetanquentin]

Description of Issue/Question

Question or maybe issue:
i want to use states.gem to install a ruby gem, but ruby is part of Software collection package. That means i have to set the environment before calling ruby,. Manually i do it this way:
1: executing the SoftwareCollection (SCL) script to set environment variables: . /opt/rh/rh-ruby23/enable
2. executing the gem command: gem install XXX

I want to do the same with salt. I don't want to use cmd.run since the state controls are not enough. I want to use the state.gem state module but it does not work with SCL even with gem_bin

So how to set environment variables via SCL script to that state.gem can work correctly?

Setup

Salt 2016.11.3

Steps to Reproduce Issue

1. ruby is installed via software collections and id installed in /opt/rh/rh-ruby23/

A script is provided to set environment variables:
/opt/rh/rh-ruby23/enable

2. Using this state:
   cfme-gem-xmlsimple:
   gem.installed:
   • user: root
   • name: xml-simple
   • gem_bin: /opt/rh/rh-ruby23/root/usr/bin/gem

won't work since dynamic libraries are not found.

Ideally using a script to set environment variable (in state.environ module?) would be usefull.

You can use the environ.setenv state, which will set the environment variable for salt, and should allow those variables to be used by anything else later in the highstate run?

@gtmanfred environ.setenv is not usefull in this case:

• it can't set variable with other environ variables as the SCL script does
• it would force us to enumerate every variables set in the SCL script so it create a dependency not well wanted here.

a environ.setenv_byscript would be better here.
