From a pants plugin, I want to inject additional paths in

PEX_EXTRA_SYS_PATH

(the pex equivalent to

PYTHONPATH

) when pants runs

pytest

or

pylint

, and maybe when using goals like

run

or

repl

. For pytest, there is a

PytestPluginSetupRequest -> PytestPluginSetup

that I can extend to allow plugins to add paths to

PEX_EXTRA_SYS_PATH

. But what about other tools. Any ideas for what a generic interface could be for plugins to inject

PYTHONPATH

(or actually

PEX_EXTRA_SYS_PATH

in most cases) entries? Should each of these gain their own plugin hook, following the pattern established for pytest, like: •

PylintPluginSetupRequest -> PylintPluginSetup

•

RunGoalPluginSetupRequest -> RunGoalPluginSetup

•

ReplGoalPluginSetupRequest -> ReplGoalPluginSetup

Or should it be something more generic like:

PluginExtraSysPathsRequest -> PluginExtraSysPaths
