Propagate JetBrains IDE proxy configuration to executed Salesforce CLI processes

[Scott Wells]

Because of the difficulty in setting environment variables on Mac such that they are properly inherited by IDE processes launched via Finder/Dock, it would be nice to have the IDE’s proxy configuration be used to set the Node.js proxy environment variables when such a configuration is present.

This should be a configurable option, and proxy credentials should never be logged.

On Mac, this should also use EnvironmentUtil#getEnvironmentMap to scrape SFDX_* and SF_* environment variables for propagation to the executed sfdx and sf commands respectively.

This is a build that should propagate the environment to executed subprocesses as follows:

On macOS, things are complicated. An app launched by a GUI launcher (Finder, Dock, Spotlight etc.) receives a pretty empty and useless environment, since standard Unix ways of setting variables via e.g. ~/.profile do not work. What's more important, there are no sane alternatives. This causes a lot of user complaints about tools working in a terminal not working when launched from the IDE. To ease their pain, the IDE loads a shell environment (see getShellEnv for gory details) and returns it as the result. And one more thing (c): locale variables on macOS are usually set by a terminal app - meaning they are missing even from a shell environment above. This again causes user complaints about tools being unable to output anything outside ASCII range when launched from the IDE. Resolved by adding LC_CTYPE variable to the map if it doesn't contain explicitly set locale variables (LANG/LC_ALL/LC_CTYPE).

I have verified that environment variables set in .zshrc are propagated properly.

Install the build by downloading (but not extracting) the attached archive, then using Settings / Preferences > Plugins > Install plugin from disk (under the gear drop-down menu) and restarting the IDE.
