feat(config): honor DISPATCH_CONFIG to override config file path#300
Merged
Conversation
Set DISPATCH_CONFIG to an absolute file path to point dispatch at a different config file, which makes it easy to keep separate profiles without editing JSON by hand. The override flows through configPath(), so config path/get/set/edit and doctor all follow it. A relative or UNC value is ignored and the default OS config location is used, matching the guard already applied to the log file path.

Closes #295
Summary
Adds a
DISPATCH_CONFIGenvironment variable that overrides the config file path. Point it at an absolute file path to keep separate profiles (for example work and personal) without editing JSON by hand.The override is resolved in one place,
configPath(), so every consumer follows it:dispatch config path/get/set/editdispatch doctorA relative or UNC value is ignored and the default OS config location is used instead. This mirrors the guard already applied to the log file path, so the override cannot point at a network share or a path relative to the current directory.
