1672721 - DXR parity: "Switch tree" menu

Status: RESOLVED FIXED

(Webtools :: Searchfox, defect)

Description

[(Away)]

This is one of the few things that I still prefer DXR for. Using DXR's "switch tree" menu to move between ESRs (while keeping the search terms) is a convenient way to coarsely navigate through time and see how code evolved.

This does sound like a nice improvement on the current approach of "manually change the URL". I think we can probably improve on DXR's approach which lists every tree it knows about (naive DOM inspector usage suggests there are 76 trees?!) and instead:

• Group trees by product and have a direct affordance for switching trees within the same product. It could also make sense to be able to switch products via a separate drop-down, which would satisfy use-cases of "I wonder what's going on for this in Thunderbird or KaiOS" without having to show those trees all the time for the normal Firefox development use-case.
• Have the tree-ordering be manually ordered rather than alphabetically ordered. This allows us to impose a more chronological ordering.

Because we shard the various incarnations of mozilla-central over multiple config files, this might imply that we should create something like "global-config.json" which could define the product groups and the order of the trees within their group. For example, we might do:

• Firefox
  • mozilla-central
  • mozilla-beta
  • mozilla-release
  • mozilla-esr78
  • mozilla-esr68
  • mozilla-esr60
  • mozilla-esr45
  • mozilla-esr31
  • mozilla-esr17
• Thunderbird
  • comm-central
  • comm-esr78
  • comm-esr68
  • comm-esr60
• MinGW
  • mingw
  • mingw-moz
• KaiOS
• glean
• nss
• WHATWG HTML spec
• TC39 ECMA262 spec
• version-control-tools
• l10n
• LLVM
