Pull Request

Problem

  • It is difficult for clients to detect whether options with default values have been specified on the command-line.
  • It is difficult for clients to manage priorities when merging in option values from different sources.

Resolves: #1584 (comment)
Related: #151 #328 #1394 #1541 #1595 #1607

Solution

The work to support .env() had to solve similar problems, and I had config and cli-detection in mind.

Make .setOptionValueWithSource() public. Add matching .getOptionValueSource().

(These routines are quite low-level with long names, but my thinking is they are tools for allowing clients to roll their own custom behaviours and won't be used by the majority of users.)

ChangeLog

  • Added: .getOptionValueSource() and .setOptionValueWithSource(), where source is one of 'default', 'env', 'config', 'cli'
