The child filters Node's ExperimentalWarning for vm.USE_MAIN_CONTEXT_DEFAULT_LOADER
and stripTypeScriptTypes, which the runtime itself triggers; an environment
initializer that imports a module under the scoped REPL otherwise prints it into
the first call's output. Warnings that programs emit still print. The host strips
types without printing the stripTypeScriptTypes warning.
run_code now discards completion values for TypeScript runtimes, so the
scoped REPL guidance shares the inspect output sentence with the other
modes. Tests read the output field, cover environment initialization with
copied bindings, and the ptc-scoped-repl snapshot is re-recorded with
inspect output.
A call that declares an earlier name again only with var now gets a var
copy of the earlier value, so a var declaration that does not run, after
a throw or in an untaken branch, keeps that value as a global var does in
Node's REPL. var count = count + 1 consequently adds to the earlier value.
A function of the same name in one call takes precedence over the var.
Update the model guidance, Agent Note, READMEs, and the ptc-scoped-repl
snapshot schema.
With replScoped: true, persistent-in-memory runs each call as a separate
VM Script in one retained context. Each call starts with copies of the
top-level bindings left by earlier calls, so a later call may declare any
earlier name again with any keyword while earlier functions and
still-running code keep their values. Results, top-level await, errors
and asynchronous failures follow the existing REPL evaluator; modules
load only through dynamic import(), resolved from the environment's first
working directory.
The control protocol moves to version 3; the upgrade guide covers
preinstalled bootstraps and the new PtcProgramFormat member. The Agent
Note records the decision and its comparison with node:repl and
vm-script, and the ptc-scoped-repl snapshot pins the model guidance.
